So I have a little weird issue. My car has been sputtering a little when sitting idle at lights and such. But once I fill it up with gas the sputtering is even more noticeable. What this is?
View 3 RepliesSo I fill up my 2007 Sonata for the very first time. I'm squeezing the trigger on the pump, it clicks off automatically when it senses it's full, then about a pint of gas backs up out of the tank and onto the floor. Is there some sort of design flaw on the Sonata that causes this to happen? It could have been a problem with the pump, but I don't usually have that happen with my other cars.
View 12 RepliesI have a 09 sonata NF. The gas pump continually clicks off while filling the tank. I saw this issue discussed here before but I cannot find it. Has to do with a vapor canister and valve?
View 1 RepliesA couple of days ago, I was about to take a long road trip. Stopped to top off gas tank (yes, I squeezed the handle a few more times than I probably should have). Restarted and drove about 300 feet. Master Warning light, check engine light, brake light and pretty car with ! in the display all came on. Drove home - car ran fine but the hybrid battery seemed to stay full, switched cars, got home the next afternoon, started car again -- all lights still on. Checked gas cap (just in case), brake fluid is between full and low, coolant is probably a little low.

The car has been sitting for around 8 hours. Wh en I start it, the idle moves up and down about 100rmps. When I drive off there is a slight hesitation until I have driven for about 10-15 minutes. The idle is nice and steady after the too.
If I use a fuel system cleaner, it appears the car is fine for awhile and then the issue comes back.
My 4 cylinder Sonata was so smooth at idle when I first got it that I couldn't tell the engine was running. Now there is some vibration noticable while sitting at stop lights (82,000 miles) .... Its gotten gradually worse but still isn't a big problem.
Is there anything typical that might cause this that I could fix? Its not extreme but there is a definite vibration that wasn't there when the car was new. My first thought was that one of the spark plugs is slightly fouled.
I usually change plugs at 75K miles so I need to do the plugs anyway. My thoughts are if its an engine mount the vibration would be much worse. Maybe its a vacuum leak somewhere ... don't know.
I have a 2008 Hyundai Sonata that overflows at most gas stations when filling. To fill the tank, I set the pump on autofill and walk away. The pump clicks off and then the car "burps" and gas comes out the filler neck and runs down the outside of the car and out the bottom. It does not do this at one gas station by my house but seems to at all others almost every time. The car is still under warranty (42,000 miles but the issue started at 29,000) and I have brought it to the dealer 3 times. Each time they claim to have found something new wrong and fix. The first time they replaced the fuel filler neck, 2nd time fuel filler neck assembly (and tested at a gas station and it worked), 3rd time the vent valve. Each time I try it and it overflows for me (except at that one gas station). I have never had this issue before with any other car including my wife's current car. I'm truly stumped, but feel that a car should be able to fill up at a gas pump without overflowing.
View 3 RepliesI was filling up my tank, as I was running in fumes a few days ago (just 14 miles before death as per trip computer) and to my surprise, when I filled my tank, it only went roughly up to 16 gallons (15.9xx to be precise) before the nozzle kept shutting off. Was the nozzle defective (or was I in a rush for not waiting until the vapors leave the tank?) or the 18.5 gallon tank has a ~2.5 gallon reserve that even the instrument gauge doesn't account for, as it was all the way in the E with the yellow gas pump icon on?
View 12 RepliesThis just gets stranger by the month. I could have sworn when I first got this 2011 Sonata that the console read 341 after filling it up for the first time. I thought it had said that after I filled it the second time (just after Hurricane Sandy - yes, before the long lines - I was lucky) and it read 329. On those occasions the console had read approx 67 & 69 miles to empty. I know I filled it with 87 the second time around. The first time may have been with 89. And when it stopped at 14.x I thought to myself, hmm, didn't it fill to 15.x the first time? Weird. So I went on with my life.
This past weekend it read 50 miles to empty and so I filled it again with 87 (same gas station I should point out). And just like the last time, before this time, it filled with 14.1xx and read 288 miles to empty. It just seems to me that "Miles to Empty" has slowly gone down. On the third filling I believe it may have read 303 to empty.
Is it me? I am imagining things here. Could have that much sludge/dirt/whatever it my tank because of the gas station I visited or the 87 and not 89 that I have been putting in? Oil and filter were changed in mid October and then again in mid March. Thats about to happen again on the 28th but also to have the required NYS Inspection done. What should I say to them if anything? Could I have picked that crappy of a local area gas station?
I fill my gas tank to 100% but I don't pump it again and overfill it like most people do after the pump stops. I then proceed to start the car. Initially it revs up and starts fine but when it revs back down to idle it does a rough idling (and sometimes it stalls). To get around the stall, I would restart and rev the engine to 3000 rpm for about 2 mins and it would be fine enough that I can drive away without it stalling but after a mile the rough idling stops and everything is back to normal. I replaced the PCV valve and it worked for about a year but it all came back again. I am stumped and every mechanic gives me a different reason and none of the reasons are even definite. It's one of those "lets try this and see what happens". One more thing, the car runs fine. It only happens when I pump more than 75% of the tank.

View 8 RepliesMy new 2015 Sonata 2.0Twith 8000 miles started running oddly about 2 weeks ago. Rough idle with engine "sputtering". Erratic acceleration -- merging into traffic on highway and car not going over 40mph, even with gas pedal all the way to the floor. On deceleration, clunky down-shifting. Very hard to drive. Dealership first came back with diagnosis of "buildup on throttle plate" (Note - I use only high-quality gas AND only have 8000 miles on car, 3500 or that being one long highway road trip). Then, after 3 days of diagnosis, they say I need 2 new fuel injectors I am baffled how a new car can have either buildup or failed fuel injectors...
View 13 RepliesMy vehicle works absolutely beautifully except between 75 and 105 km/hr where I experience sputtering. This does not happen under load but just when I am maintaining a constant speed. It feels like misfires but I don't get a check engine light when it occurs. Misfires would definitely trigger the check engine light. I've tried the obvious solutions:
Used fuel system cleaner in case I got a bad tank of gas
Used fuel additive to eliminate any water in the tank
Changed the oil and filter (it was due anyway)
Replaced the air filter (it was also due)
Cleaned the MAF Sensor
Replaced the spark plugs
None of this has made any appreciable difference in the performance of the vehicle. The sputtering persists.
The car does not have traditional spark plug wires. Instead it has ignition coils which run about $140 each from the dealership. I may eventually have to change one or more coils but I'll try cheaper solutions first.
My next step is to replace the crankshaft position sensor. You may have noticed that I am problem solving starting with the least expensive solution and progressing to more expensive repairs.
I just bought a 2010 Accent for my daughter and this was the 2nd time I filled it up. I realize now I should not have topped it off all the way but I did. The tank was probably bone dry when I filled it up as well. Within 5 miles after I filled it up, it started running rough and the check engine light came on. I stopped it and checked around under the hood. Checked to make sure the gas cap was tight. I drove it again and it appeared to run fine. I stopped by an Autozone and had the code checked. It was a misfire code for cylinder 3.
Drove it home (10 miles) and parked it. I took the battery terminal off and cleared the CEL. When my wife drove it a few minutes later, the CEL came on again and it started running rough. Had the code checked again and the cylinder 3 code came back. The guy at Autozone said over-filling the tank when it was empty probably caused too much pressure on the fuel going into cylinder 3 and that it should correct itself in the next few days. I drove it 20 miles to work today without any problems. It seemed like it had to be related to filling up the tank since it happened a few minutes later.
Today I went and test drove a used 2006 Dodge Stratus SXT from a private party. Everything about the car was great except it had a bit of a rough idle; there was a slight sputtering noise when not in motion, and the car itself vibrated very slightly. It didn't bother me too much while I was driving because it accelerated and shifted fine and the engine sounded very strong, otherwise.
When the test drive was over I pointed out the noise to the owner, and he admitted that he had mis-timed the timing belt slightly which was causing the sputtering (he is a mechanic and replaced it himself). I was worried about this, but I did some research when I got home and learned that this model of Stratus has a non-interference engine.
My question is this: should that timing belt be a deal breaker for me? Will this cause major mechanical issues down the road? I know it will reduce power but I only really need the car to commute, so I don't mind if I'm not toe-to-toe with a Challenger. I'm just worried it will eventually cause a costly problem.
I am getting a terrible creaking noise when the car is cold after sitting all night . I've tried to isolate the area where the noise is coming from, but it varies from side to side. I have shot all movable parts with PB Blaster and it appears to work somewhat . I never noticed it until the cold weather. Where to look maybe engine cradle mount areas? 2010 Sonata 2.4 GLS
View 6 RepliesI hear a squeaking noise when I start my car. It is mostly in the mornings. Sometimes other parts of the day also. I believe it is on cold start because I usually hear it when the car has been sitting for a few hours.
My first thought was that it may be the belt so I popped the hood and looked at it. The belt seemed nice and tight and there were no cracks or extensive wear on it.
Second thought was brakes. My front brake pads are good but rear brake pads are close to needing replacement. Sometimes when I brake I hear the squeaking noise but it is hard to tell because at time it feels like it is coming from other cars.
Could the brakes be the cause of this sound? Even though it is at start up and not constant.
Car is 2007 Sonata with 100k+ miles on it.
A few months ago I bought a used 2007 Mercedes C280. Overall, I've been very happy with the car. The first month or so was heavy on longer highway driving, and it seemed to be getting decent gas mileage. The last couple of months have been mostly short range city driving, and the mileage seems significantly less. I wonder about the idle speed, on the assumption that it may be wasting a lot of gas sitting at stop lights and in traffic. The tachometer reading isn't always consistent at idle, but fairly often it's up close to 9,000 rpm. What should I be seeing, and does this need attention?
View 6 RepliesMy CEL came on today, gas level was a little under a quarter tank.
Took it to Advanced on the way home to have them scan it quick, and it threw a fuel pressure regulator code. I stopped in the gas station on the way home and filled it up, and the CEL was gone and hasn't been on since. I'm thinking HPFP, but maybe not? Could it be injectors?
My partner drove the Prius with 54,000 miles to work this morning as he always does. So he is on lunch and sent me a text saying some warning lights appeared on the dash while he was sitting at a red light. I asked if he had any loss of power, if the battery fan was running, he said it drove normally. We bought it last summer with 44,000 miles from a Toyota dealer. They said it had a new inverter pump. It has the original 12v battery however. Though it doesn't act weak at all. No issues this winter at all.
Note, the battery in the photo is at 1 bar. I asked him about it and he said he was driving aggressively to work today, which includes a 2 mile 6% climb he said he made at a high rate of speed... Though after the exit, he has another mile to work.. So the battery should have built itself up before him parking it.
Having a problem with the 2008 Sonata GLS. When filling gas tank, pump nozzle clicks off, but gas flow continues, creating a significant spillage.
