Accent MC (2006-11) :: Quick Hiss Just Before Shifting Under Load
Jul 4, 2016
Daughter's 09 Accent 86k miles making a very quick hiss when accelerating rapidly and/or uphill about a half second before first shift. Hiss stops noticeably before the shift happens. She reports a slight 'kickback' in the pedal, but I noticed no power loss when the passenger seat. No check engine light. Car has an aftermarket cruise. Sound seems to be coming from the right-ish side of the vehicle and outside the cabin. Doesn't occur under 'grandpa' driving conditions. Pretty much only when using the accelerator as a binary switch.

I have a 2004 f150 lariat crew cab 4x4 with the 5.4 3 valve. It now has 113 000 miles. Since i got it at 85 000 miles its had a hiss when the engine was under load. So like light acceleration or driving into wind. The guy i bought it from said that it had a manifold leak so that's what i figured it was. I got the manifold fixed and it still hisses. There are no check engine lights. It almost feels like my engine lags when it starts hissing. It sounds like its coming from right on the other side of the fire wall. What it could be?

Since they replaced my transmission at 40,000 miles, I've noticed that occasionally, but not always, there is an unusual quick half second jerk or jump feeling when I first crank the car on a cold start. It doesn't happen all the time, just some times, but it has to be a cold start when I do feel it. What this could be? I'm thinking maybe some bolts weren't put tight enough when they installed the new transmission?

2008 Hyunda Accent, 5 speed, with high mileage. She claims it slips out of 5th gear when she's driving. They're on vacation, the car is in the shop, the shop is saying that it can't find the problem...
Apparently it slips out under load (in constant motion).
It seems that it only occurs when the transmission is hot, meaning the oil has less viscosity. The dealership apparently is saying they can't find anything wrong and she isn't making it up since she said she drove from Michigan last week with her hand on the shifter the entire time to keep it in gear. Dealer is saying they aren't going to just drive it around and around until it happens.
How modern cars are built these days. I know older cars had some synchro things that would wear and allow the shifter to pop out of gear, but I read that some Hyundais have cable driven shifters....at a loss.
It happens in 4th sometimes, too, and will also pop out even when leaning on the shifter.
I did see this thread, but was wondering if there was any additional information: [URL] .....

My wife has an 09 accent equipped with the 1.6 and 5spd manual. When it gets cold (close to freezing and under) fourth gear starts to make a whining/growling noise that gets louder with more load. Once it is warm it completely goes away. What is going on here?

Had this happen to me a few times now. Driving down the highway (120kph) in 5th, revving around 3,000 or so and whenever I hit a hill and come onto the gas pedal, I hear a ticking sound coming from up front. The harder I press on the gas - the louder it gets and vice versa.
Only happens in 5th and only under load. Scanned for codes - nothing, looked under the hood - looks normal. Timing belt was done around 56,000km, car has about 67,000km now and is in fantastic shape otherwise.
Spark plugs are still original and I have a new set waiting to go in, drive belts were replaced back in the spring but the tension is correct and all pulleys were checked okay at the time.

My '07 seems to stumble when it's shifting from 1st to 2nd and 2nd to 3rd. At first I thought it was me as I spent the last six - seven years babying the tranny in my old Ford by 'lift shifting' but I've found it still does it somewhat when I'm accelerating and not letting off to let the car shift. Is this typical for the automatic in the Accent? I had the tranny serviced not 1,200 miles ago in June or July at Firestone and they assured me and showed me their fluid was compatible with SP III.
This happens especially when the car's cold or just warmed up. Seems to mostly but not completely go away after driving for a good half hour or so.
I've only got about a week or two left on the warranty but I also don't want to dump money into diagnostic fees if this is how these modern transmissions behave.

I just picked up my R32 2 days ago and I notice that when it shifts up semi-aggressive (around 4.5 rpm) there is a quick swish sound as the gear engages. It sounds like it is coming from the muffler system, in the rear. What it is?

My friend has a 2007 accent with a manual transmission they said that they were driving and the transmission stopped shifting gears. The clutch pedal still has pressure so I don't think it is a master or slave cylinder issue. They freaked out and turned off the car and now the car will not start up again. Have any of you experienced anything like this before or know on this car where to start looking? I think the issue with not being able to switch gears could be a pressure plate issue but this would not cause the car not to start.

My friend told me the other day her car was in overdrive (hwy driving) and suddenly, it shifted to a lower gear. It seems no one knows why. She does have an extended warranty, but the garage might charge her $300 to open it up to see what is wrong. Another friend suggested a clogged filter. Another one, a sensor.

My 2009 Accent has some very rough shifts from 1st to 2nd when I'm in the low RPMs.
Hyundai performed a transmission fluid flush and the other gears shift completely effortlessly. Is my tranny dying or what?

I recently installed an AEM intake on my 08 Accent GLS with an automatic trans. After I installed it I noticed the trans shifting funny into 4th gear. Before shifting into 4th the RPM's will drop accelerate a little more then it will shift into 4th. I've thought about switching to Royal Purple trans fluid to see if it will fix the problem.

I own an automatic 2009 Accent. I'm at 95,000KM.
Anyway, the problem does not occur all the time and appears to be entirely random.
When I start my car, on occasion, the car will make a CLUNK sound when shifting from park to reverse or drive. When it does CLUNK, you can feel the car lurch as if something fell out of place. The sound is quite audible, even with the radio on. The sound and lurch is not as pronounced when shifting to reverse. It doesn't seem to happen when going to neutral but is very obvious when going to drive.
Turning off the engine and restarting it seems to resolve the issue. Once I had to restart the engine twice before the clunk stopped.
Attempting to drive when the car does this sound results in increased RPMS. Usually when driving the RPMS sit between 2000 and 3000 but would jump to between 3000 and 4000 when the clunk occurs. Usually, the car will want to crawl forward if I'm not on the brakes but with the clunk, the car need quite some gas to start going forward.
Here's where it gets scary:
On two occasions, while driving on the highway at 100km (65 miles), I'd feel something slip and then suddenly my RPMS jump up by 1000. On both occasions I had to pull over, turn off engine and restart the car and the issue stopped.
Clearly, whatever it is that changes gears is slipping but the fact that it slips while driving just freaks me out.

So went today and bought a 1993 ranger 4x4 ext cab 4.0! Runs good some bad handy work that i need to fix but truck has plenty of power and good handling...
issue 1- 4x4 not engaging. the light by the push buttons does not come on and you dont hear the "clicking" of the relay trying to engage. so whats the problem and how do i fix it?
issue 2- when clutch is fully depressed and you go to shift (this is only sometimes) you can feel and hear it grind just for a quick sec. and forget about down shifting you cant do that without slowing down. so maybe new clutch?
issue 3- at 65 the vehicle does shake a little otherwise but pretty smooth. any tips on how to smooth it out? maybe new ball joints? tighten some stuff up maybe?

At some point in time I noticed that when I turn on the rear defroster a hiss develops in my (factory-installed) radio, operating on the FM band. Most of the time this hiss is strong enough to mask the audio entirely. I noticed, too, that one or possibly two "printed wires" in the rear window may no longer be operating; however, I don't know whether this is connected to the hiss problem.

Lately my transmission has delayed shifting into first when I shift my car into drive on cold starts. It delays for usually about 2-3 seconds then kicks hard into first. The rest of the shifts are smooth and on time. I've tried replacing my transmission fluid, but that doesn't seem to fix it. Is there an actual problem with my transmission? I had the TCM replaced when it would get stuck and not shift. I have a 2009 GLS with around 53k on it.

I have a 2008 Accent (base model for the most part, no C/C), and my transmission seems to be slipping a bit. The symptoms are: slow acceleration, a delay in gear shifting, and after the 30MPH mark, it takes forever to get up to anything near 60. I just wanted to know if it's a simple solution such as topping off the transmission fluid, or if it's a bigger issue.

While driving, I occasionally hear a hiss, which seems to be a/c related. but just recently, I've heard an extremely high-pitched squeal/whistle. So high-pitched I had to slow down, turn off the music, and tell my wife to stop talking :P to hear it. Brakes are not being pressed. Definitely not a brake problem. How do I know? I parked the car, with engine running, opened the hood, and looked for the sound. nothing. I turned off the car and was walking inside when i heard it whistling behind me, mockingly. it stopped shortly after.
I'm thinking it might be a/c related, or some kind of pressure hose. (a/c is working fine otherwise, as far as i know). It's not air leaking from the tire. I've heard it on and off for about a week and the tire pressure is fine.
I'm more mechanical with computers than cars, but i have a basic understanding. it seems to be coming from the driver side, under the dash/under the hood.

I have an '05 accent with an auto trans. The car only has 25k on it with the original trans fluid. Every once in a while the trans will thud when coming to a quick stop. It actually doesn't even make a noise, but you can feel it going into presumably 1st gear. It only happens when I need to semi-quickly stop for a yellow light etc. right as I'm coming to a complete stop. Trans seems completely fine otherwise. Is this a normal thing? Just an older style/technology auto?

My year-old Camry hybrid stalled out last night. It was the second time this has happened. The first time, about a month ago, I made a quick start from a light, followed by a quick stop, both actions to avoid an accident. (I was about to get rear-ended and scooted into the intersection to give the guy closing in my mirror more room.) After the stop, the car had no power but it started up, no problem. Last night, I was about a minute into my trip, stopped at a light, and the power just died. Again, it started no problem.
This time I noticed that the radio went out. Not sure about the headlights. The emergency blinkers came on at the touch of the button before I restarted. In both cases, I stepped on the accelerator and got no power. Took it to the dealer and they couldn't replicate the problem, of course, and whatever interrogation they did of the systems found no faults. They had to be convinced that I knew the difference between an actual stall and just going from gas to electric. It's kind of disconcerting to just stall out in the middle of the street. And I'm concerned that this is a problem that could get worse -- probably just after the warranty lapses.

We have a 2010 Santa Fe AWD LTD with about 140, 000km on it. It recently came back from front suspension work. The suspension is fine now, but we notice harder shifts in the transmission. Also, there seems to be a vibration just before shifting gears and when under load (like going up hill) seems to slip (like on ice) about once every second until the shift is made. Once the shift is made it drive smoothly until put under pressure again. Even stepping down a bit on the accelerator will cause this slipping feeling (or maybe its loss of power). Just had new plugs put in and a tuneup so it's not that. Could something from the suspension work cause these symptoms?
