I have a 2007 Elantra. Sometimes it starts, sometimes not. We've had it to the dealership and a local mechanic. No luck. No one seems to know what the problem is.
The fuel pump has been replaced, a new battery, the relay (?).
When you turn the key it either starts or.... Tries to start and it doesn't' seem electrical because if you pump the gas petal (and you get lucky) it might start after a few times of doing this.
Over the last half of the summer my A/C stopped working on three separate occasions. Surprisingly none during the day (~100 at the time) all happened at night. I would drive somewhere with the A/C on with no issue, however when I would get back in my car 5-30 minutes later nothing would come on. The A/C and recirculate light would come on as usual, but no air at all from the vents. I tried restarting the car, checked the fuses, nothing. Then maybe an hour or two later it would come back on. So far this has happened 4 times, with the most recent being a week ago. I took it to a dealer when it first started happening and they could not find anything out of the ordinary. The last time it happened, I drove straight to the dealer, only to have my A/C come on 50 ft from the dealer. Another odd symptom I have seen is when I switch the A/C to the off position occasionally it will come back on for two seconds and shut off. (electrical maybe?) At fan speed two it makes a quiet ticking noise that it didn't make when I first bought the car (though my '01 Accent made the same noise).
View 7 RepliesI have a 2010 Elantra and use the aux jack all the time for my iPod. About 3 months ago it would intermittently go mono and then I would jiggle the cable going to the aux jack and it would resume stereo. Now it is full time mono through the left speakers only and I have tried to switch cables with no success.
When I was in for service, I mentioned this to the dealer and he told me it is because I was not using a "Hyundai" cable to connect. Now I know this is B.S. as it is an industry standard headphone jack. Another client at the counter said hers was doing the same thing too.
I was thinking I had to pull the aux connector out of the radio and look for a loose wire or something.
My car has been running great. It has 125,000 miles on it. A couple weeks ago I did a bunch of work. I changed the plugs, air filter, timing belt, ac belt, alt, belt, cooling flush, tranny flush and brakes. Everything was great until yesterday. I wanted to test the power so I was on the highway going up this long incline going relatively fast. As I get almost to the top of the hill, my car starts hesitating losing power and check engine light comes on. I make it off the exit and sputter to a commuter parking lot. I shut the car off, check under the car for leaks and check the fluids. Everything is ok. I start the car back up and its running fine again. I drive home then I drive to the parts store to have them check the codes. No codes found. He told me that the engine light needs to be on for them to find codes.

I have had no issues with the car until about 2 weeks ago. Suddenly the EPS light came on and I lost power steering. Upon pulling over and restarting the car the problem went away. I went about a week, and suddenly it did it again. Restarted car, went away, still does this intermittently.
I took it to the dealer, they found the following codes:
EPS - Electronic Power - C1259 - Steering Angle Sensor Electrical
EPS - Electronic Power - C1290 - Torque Sensor Main Signal Fault
EPS - Electronic Power - C1604ECU(Brake System) Hardware error
EPS - Electronic Power - C2400 - Motor
ABSESC - ABS/ESC - C1202 - Wheel Speed Sensor Front - LH Invalid/No Signal
ABSESC - ABS/ESC - C1208 - Wheel Speed Sensor Front - LH Invalid/No Signal
ABSESC - ABS/ESC - C1211 - Wheel Speed Sensor Front - LH Invalid/No Signal
They reset the codes, and EPS Reflash. Recalibrated EPS. They told me if the problem comes back I would need a new steering column ($1500+). This seems a bit strange to me for an intermittent issue. It would almost seem to me that if multiple sensors are effected that they are receiving bad data from somewhere. Could the ABS sensors be causing this problem with bad data? I've also heard a failing battery could cause this type of issue.
I have a 2007 Elantra and I have been having problems with the clock light flickering intermittently. I took it to Hyundai and they replaced the clock unit and that hasn't fixed the problem. They said they have checked all the fuses and there isn't a problem with the fuses. What the problem might be? It is very annoying when driving, especially at night.
View 2 RepliesI have a 2009 Hyundai Elantra. I've been having an issue where my radio turns off and on intermittently. To clarify, it will not turn itself on if the button was off. However, if I'm listening to the radio it can turn itself off and back on again multiple times. This happens on AM/FM/AM and Auxiliary. I'm assuming it happens with CD, but haven't listened to that lately.
Sometimes it happens in rapid succession, other times it's off for five minutes or more and comes back on. Other times it stays off. Sometimes it behaves as it should. It doesn't seem to matter if the car is warmed up or not. Is this merely a wonky fuse or something more sinister?
I have a 2008 Elantra w/ 108K miles. The current issue is the heat/ac blower intermittently not working. On Christmas Eve I started to drive it and realized the windshield was fogged up because blower was not working. The next day it worked fine...we chalked it up to maybe being related to having plugged a crock pot into the cigarette lighter (with a plug convertor thing)...wishful thinking that maybe something just got "overloaded." It has been working fine since, except last night when I started it, same thing--no air blowing on any of the settings (I read that if setting 4 works, but not 1-3, it makes a difference w/ the diagnosis). And, then again today...it works fine. Other things that I have noticed/that have happened in the past year or so (possibly unrelated, but figured it couldn't hurt to mention them just in case):
June 2013--started intermittently hearing a loud buzzing type sound (at first thought it was my phone vibrating)...sometimes would happen randomly, but mostly when I would adjust the heat/ac...sound coming from the passenger side front of the car floor area (maybe under glove box where I know the blower motor is). The buzzing would last anywhere from 2-20 seconds. Never did anything about it since everything was working fine...
Last winter--while driving home during a heavy snow storm w/ defrost on high and windshield wipers going noticed that the fan/blower seemed to "surge" when I stepped on the gas..like the blower would slow down when I braked and blast out much more air louder when I accelerated. I noticed this again tonight...possibly it has been ongoing and I just have not noticed.
Early Dec 2014-present--unable to adjust the temp setting...despite twisting the knob from red to blue, it remained hot air. Assumed it's the blend door, but figured we'd deal w/ it in the spring when I needed cold air again!
What this could be (or an overall problem that would explain all the problems?).
My 1999 Volvo V70 is having intermittent issues starting/stalling out. Sometimes it will start right up and go, other times, it will start and the rpms will fluctuate then it stalls/shuts off or will go in gear but fluctuate rpms erratically it will do this multiple times after 3 or more restarts it will run fine until it is turned off then the same thing all over again.
View 2 RepliesMy Plymouth Breeze is having issues starting up. It started a while back, my wife was driving the car and she got stranded because her car wouldn't start. I gave her a jump. I had the battery and alternator tested and the battery was bad, but supposedly that alternator is good--so I replaced the battery. We get a week or twos use out of it, and the the rear brakes sprung a leak-- so I replaced the rear brake lines. When I tried take the new brakes lines for a test drive the car wouldn't start. I have a battery charger and used the 50 amp start feature, the car would still not start (it would turn over but not start). So I gave the battery a deep charge from the battery charger and the next day it was fine. My wife used it for a week and all seemed well. That is until the other day where she tells me it has a new problem.
Apparently the defroster randomly turns off and on, and the vent constantly switches which direction it is blowing. She took it out for a drive while it was like this and got stranded again. I went to give her a jump and the car wouldn't start at all. In fact none of the electrical came on, it was as if the battery had been disconnected. So we eventually get the car towed, and as I put the key in the ignition to put the car in neutral I hear the beeping to indicate the car door is open. I tried to start it and all of the electrical shut off again. So the guys tows car back, having to push it into a parking spot. I realized the tow truck driver left the keys in the ignition and it just occurs to me he had rolled the window down. I get in the car and turn the key and it starts up without hesitation, like there were not problems at all. Needless to say I'm a little confused and frustrated with this car. I'd like to get another year or so out of it before I replace it.
So here is what I am thinking...Battery: This should be fine I just replaced it.Alternator: I had it tested coupled with the last scenario leads me to believe this probably isn't the problem, but is suspect.Starter: This seems to work when there is power, so I don't think that is it.Fuses: They either work or they don't, there is no "getting better" so I doubt it is a fuse.Computer: I think this might be the culprit. Before I had to give it another jump (when it wouldn't take) things were turning off and on at random. It is also the only thing I can think of that might act in a fickle way.
Another theory is a loose wire coming off of the battery.
For some time I've thought my starter is going bad because I'll have to hit the ignition multiple times for it to actually start...I've even had to resort to push-starting it a couple of times. How can I tell if this is a bad starter or something else like the main relay?
View 4 RepliesMy 07 tundra starts and then stops running it does this intermittently. I recently put in new battery.
View 2 RepliesI have a 1995 buick roadmaster with 308,000 miles. The car quits intermittently but starts up immediately thereafter. Seems like an electrical issue but it doesn't act like the distributor is malfunctioning or fuel stoppage since it doesn't shudder prior to quitting. I have had the car since new, we love it and would like to keep it.
View 6 RepliesMy Jeep does not always start. All the dash lights come on, but when I turn the key to start the engine, they all go off. The lights stay off, and the engine will not start. The ignition won't even click... it's similar to a dead battery. When I turn the key back to its original position (when first inserting), all the gauges spike and the needles jump really high for a split second. When the door is open the gauges keep jumping (spiking). After waiting for 30 minutes, the engine will start fine like nothing was wrong (except the fluctuation in idle). It would rev high at idle sometimes, and sometimes it would idle low... so low in fact the jeep stalls. I have read about the symptoms of crank/camshaft sensors and relay, but I wanted to make sure from people that know more than I or have faced this particular problem.
View 5 RepliesI have a 98 Chrysler Concord Lxi with a 3.2 L V6. In the summer time when its hot The car will get warmer than normal (I have figured out that one of the cooling fans is out and needs to be replaced). That said. after running for a few hours on the highway and if sat idle with the temperature raised, if I shut the car off 9 times out of 10 when I go to restart the car it will crank and crank but will not fire. My guess is the computer shuts the fuel off.
I have to wait about 30 minutes and it will start. Sometimes it will start very rough with a carbon smell and the need to idle it high until it smooths out. Other times It will start with out having to wait but the idle is again rough and can smell carbon. I have looked online and found some have a solution of releasing the pressure of the fuel line as it could be a symptom of vapor lock. I have tried this and no pressure is released ( I have disconnected A/C Lines on previous cars only to find a large BOOM a mess in the garage and in my shorts!) so I know I am releasing the right Scraeder valve.
I have a 2001 Dodge Grand Caravan that has some intermittent starting issues.
Symptoms: put key in, dash lights up. turn key, 1 "click", and then nothing, won't start, no extended clicking or anything. Sometimes it will start after a few tries, sometimes come back later and it works. Battery also seems to drain relatively quickly sitting, and so sometimes needs to be jumped if sitting for a few days.
Also, had a really strange experience where after it had to be jumped while driving, the dash and blinker totally went out, but car kept running. This happened a couple of times. I suspected something with the battery, so I had it tested and it checked out OK. Also, cleaned the terminals/battery cables w/ cleaner, wire brush, steel wool and sprayed some corrosion prevention stuff on there. It did need to be cleaned, but, alas, the problem continues.
The car is a 2002 VW Jetta, automatic 1.8t GLS. 146k miles on it. Has an external amp/sub wired up by my brother who is an MECP certified tech and has been doing car audio and overall Audi/VW for years.
I was driving, nothing out of the usual, this car is my daily. Stopped because of traffic and my car died in the middle of traffic, the gauges (tach, speedo, gas, etc) spiked immediately, which I assumed meant loss of electricity, but my radio, headlights and everything else stayed on. The oil and Battery lights came on as well. Tried to start it, it was trying to start, and was cranking quickly, but wouldn't turn over. I got it out of traffic. I pulled my amp power and the car turned over and started driving like normal, so i figured there had been a short in the wire and that was what caused my issue. Drove about a half mile down the road, car shut off again, car said it needed oil this time. checked the oil, there was plenty, but i put more in to be safe, and it turned right over and i managed to drive it about 30 minutes and got it back to my house.
So, my brother and i look the car over, couldn't find anything really wrong with it, so we took it out for a drive, no problem at all for the first few minutes of driving. Car shuts off again, doing the same thing, but just the battery light came on. My brother jumped my car, it turned over, but as i started to drive it, it was a lot more rough with shifting (possibly tied to electrical problems because i know there is a solenoid cluster for automatic transmissions), i mean you could actually hear the gears shifting and the car was kicking through each gear, as well as my driver side headlight not turning on (just installed brand new xantec 6k 55w HIDs, but i dont think those are the problem because the problem started before i installed the HIDs) and died 3 more times before i got it home, having to jump the car every single time with symptoms the same as the first time it died without the oil light. Another thing i noticed is that the car seemed to only die when i hit the brakes and the car went to low RPMs, which lead me to believe a major vacuum leak. At idle the car also seemed like it was misfiring even though the CEL was not flashing, it just had the jerking feeling and sound of misfiring.
My brother and i take a better look into the bay area, and noticed that the top of my engine was covered in oil, from the intake manifold back. I know my car has been leaking oil, but not spraying it. We pulled everything apart, totally cleaned the engine bay area out including MAF, spark plugs, coil packs etc. The engine bay area looked practically brand new. Now i do know that my car has had a vacuum leak (no boost gauge to tell how bad, but the brakes were a little bit less responsive and the car was acting as though it was misfiring despite the fact that the coil packs and spark plugs are brand new) and we couldn't find where it was, and we thought that maybe that was the problem. A lot of the vacuum line was dry rotted and falling apart and some parts weren't even connected anymore from that, which we replaced all of the line we could find to eliminate the idea of a vacuum leak causing the car to die when i hit the brakes. We also tested the battery with a multi-meter which read variably between 13.8-14 V, which if i understand correctly is within normal range, but oddly enough we put the battery through a stress test including turning on defrosted, turning sound system back on, headlights on etc, and the voltage didn't read much different, still bouncing between 13.8-14.
When tearing things apart, we also found that the starter solenoid was unbelievably loose due to a bad transmission mount, and one bolt was missing, so we were thinking that could be arcing causing the problems, but when the solenoid was tightened down, the problems still persisted.
Started the car, let it warm up, and it seemed perfectly fine. I drove it into town without problems, but forgot my wallet at home, so i had to turn around and go back. Almost made it home, the car died while stopping at a stop sign. Tried turning it back over, nothing the first 3 times, let it sit for about 5 minutes and the car turned right over as if nothing was wrong. Died again when i made it into my driveway about 0.5 miles away and the symptoms repeated until the car finally just turns on like normal now, but the idle is at 1100 RPMS (not sure if related or not) even though the car is at the optimal temperature. I tried driving it again after the car starts normally like it does now, but it just repeats the symptoms that it has been, cutting off but leaving the stereo, headlights etc on. I managed to get it back in my driveway.
Let me tell you a story ‘bout my daughter’s 2008 Chrysler Sebring 2.4L…
We have owned the car since 2009. Recently the car has begun to start intermittently. Generally it starts normally. Other times it won’t. It can be driven for a month with no problem and then BAM! It won’t start. No dead battery sound, no clicking, no starter trying to engage NUTT’N!
AND… the brake pedal is firm! The brake pedal is firm and cannot be pushed down!
The car has been to the Dodge dealer several times. They have replaced the starter because a couple of teeth were missing, flashed the computer and replaced the alternator. The car started fine for a few days and then wouldn’t start again.
The Dodge boys kept the car for a week and of course, it started fine while they had it. One of the service managers told me to pull out a certain fuse to reset the computer. They also told me that they usually see these types of problems if the car was jump started wrong (the jumper cables were hooked up backwards I guess).
I have a 2001 F350 V10 Crew Cab that has 51000 miles on it so it doesn't get driven all that much, but I do start it at least once a week and it has always started on the first crank.
A couple weeks ago I drove over a friends, I backed up her driveway, turned the truck off and went inside. After returning I went to start the truck and it wouldn't start, just cranked. Probably had between 1/4 and 1/2 full.
I let it coast down to the level and it still wouldn't start. Finally had it towed home. When I got home I tried it and it started right up. Next day it just cranked and wouldn't start. The day after it started right up, I ran it for 20 minutes, turned it off, tried to start it and it just cranked....
Then I started looking at forum's for a possible answer.
I already had an IAC that I bought a few months ago since it was idling a little rough that I installed. Still started intermittently.
When I listen closely when I hear the fuel pump run when I turn the key it starts right up, when I can't hear the pump it won't start.
I have tried moving the relays around that are in the fuse panel on the drivers side hood, moving the fuel pump one to the blower motor and vice versa. Still starts intermittently and only when I hear the pump run.
I looked for the FPDM that in some trucks is up by the spare tire but apparently my truck doesn't have one, or at least in that location..
My next thought is that it must be a bad pump...Can a bad fuel pump act like this, sometimes work and sometimes not?
Dad's 2000 F150 5.4 ltr will start intermittently, when it does fire it runs fine, but right after start up all the dash gauges "spike" to the max levels for a sec and then go back down to normal....
Put the Cen-Tec 98614 code reader on and it continues to say "Link error" and I can't communicate to the interface. P.S., I confirmed the Code reader is good by pulling a 420 O2 sensor code from my Toyota in just a few seconds....
I can hear the fuel pump kick in so I doubt that is the culprit. Because of the gauge spike at start up (every time) this problem screams grounding problem, but I don't know where to start. Could it be a faulty relay?
I have a 2001 Hyundai Elantra. For a few weeks my car would not start if it had been driven a lot in one day but than it would start the next morning. Now over the weekend even after sitting it will not start at all. I have changed the positive terminal and the relay switch. There is a little under a quarter tank of gas and I have never let it get so low but did for further testing. What it might be? I just replaced the starter a few months ago and it has gave no recent indication of it going bad. There is a valve gasket leak that I need to get replaced but I don't think that would cause it not start...but than again who knows
