The owner of the car claims that there was sudden unintended acceleration, and it was 09' Sonata.
Video .....
I thought this should be very concerned to us, since we all drive 11' sonata & up. I heard Hyundai installs some kinds of system to prevent this incident to all cars manufactured after May of 2012.
I have a 2010 santa fe with 19k miles.....twice this week i was driving and suddenly the gas pedal stopped working and engine light came on. brakes worked. Have "Sudden Unintended Deceleration"??
After the first event, i had it towed to the dealer (following protocol in the manual). they reported a new recall (it had been serviced a few months ago), executed a computer update and all was fixed (or so i thought).
4 days later, with less than 100 miles driven since the repair, it happened again. this time i was in 35mph traffic so when the accelerator pedal no longer worked, i almost was rear-ended. i was able to coast out of traffic (brakes and steering fine)to a side street. i was able to coast home (.5 mile or so). car would accelerate after stop signs, although the gas pedal doesn't respond at all. very scary that it even shifted to a higher gear and would go 30mph and keep accelerating if i didn't brake!
I've read quite a few instances in this forum of unintended acceleration in the Toyota Sienna. Well it happened to me this morning. I was pulling into my parking spot at work with my foot lightly on the brake, going about 5 or 10 mph when the vehicle suddenly accelerated as if someone had floored the accelerator. The vehicle went up over the curb and into the side of the building. When I told the policeman what had happened, he said that isn't possible. I told him it was possible because it just happened to me. I had it towed to the dealership, called my insurance company and Toyota to make a report of the incident. They will be sending someone out to check out the car, but I'm sure they won't say there is anything wrong with it. I'm sure it won't be impartial since they don't want to be held liable. I also made a complaint with the NHTSA. I am afraid to drive the car and will never buy a Toyota again.

That's when the engine rev'd to 7k RPM's. Initially it quieted in neutral and I drifted to the shoulder with one shift back into D and 7k RPMs for a bit of power. After that, any start and it revs immediately to 7K upon start.
Flat bedded to Santa Monica VW and await Ivan, their Phaeton mechanic to return tomorrow. Service writer Jeff wondered about front suspension but connection to acceleration is a mystery.
My 2013 goes 7mph with the foot off the gas. Why is it doing this and is there any way to correct this?
Is this normal? I have to keep my foot jammed on the brake to stop the car from lurching forward.
I have a scary problem with my 2005 Civic Coupe HX CVT that the dealer can't resolve - my car drives forward and even accelerates when my foot's not on the gas! This is a recipe for disaster, especially since I live in a cold climate and there's so much ice and snow in winter.
I thought at first I must be crazy. So I've tested it by taking my foot off the gas going up a small incline, and Voila! It drives up the hill! It also can drive around the block by itself! It's like the energizer bunny, and I'm scared to drive it anymore.
The dealer has no clue why this is happening and can't seem to replicate the problem. I've brought it in more than once, too.
It happens most often when my car's been parked for awhile, say 6 hours or more, and if it's really cold outside, say less than 32 degrees outside. Also the heater's usually on when it happens, but that may be incidental since it's usually cold when the problem occurs...
Also, There's a whine that sounds like a belt that gets loud when the air conditioner runs and also if it's really rainy. I've taken it in to the dealer a couple different times and they fix it, but then the sound comes back again. Could this be related?
I've got a noise in the front end of my GLS (52K miles). It's kind of hard to make it happen, but I hear it 2-3 times a day. It doesn't usually happen hitting a bump, but is usually heard when the weight of the vehicle shifts, when there's a sudden incline or drop, like when pulling into a driveway or gas station.
I had a car with a motor mount issue once, which sounded similar. However, I actually had my motor swapped 5K ago, and my noise existed before that.
I have to get to the dealer (I believe 60K is the end of coverage for this kind of thing). I would like to have a little more info or suggestion of what to check, otherwise it will be "we don't hear anything."
My husband and I bought a 1995 Ford Crown Victoria not too long ago. We have already had to replace the brake lines 2 times (well, first the front and then a few weeks later the back). It has had nothing but problems. One thing is the air conditioner, but that probably just needs charged.
Now on to the bigger problems. All of a sudden we started having unintended acceleration. It is strong enough that if you don't have the brake pressed hard it will move your car forward every 5 seconds. The engine revs up on its own. This happens every time we stop anywhere. Including when I was pulling into a parking spot last night. I went very slow and as I was turning pressing on the brake it revved up and I thought for sure the way it jerked, it was going to go over the curb into the road. This scares the crap out of me.
Also, we have a problem with the slow (very slow) start. I know they had a recall on the cruise control, but I have not heard of any recalls on this. However, I did read somewhere about accidents happening due to this and something about it had to do with the way Ford build the car.
I took my 2011 Lariat in for first service and reported that it sometimes tries to accelerate on its own during slowdown from high speed, eg when coming off a freeway ramp, rpms go up and vehicle wants to speed up rather than slow down. (sounds like something a Toyota would do!)
Dealer says its a known problem with 5.0L and performed a supposed fix per "TSB 11-8-9, 5.0L ENGINE BRAKING PERFORMANCE DURING LOW SPEED COAST DOWN," essentially a PCM reflash.
Happened once in a parking lot...thought the floormat was stuck on the accelerator but the pedal was clear.
So I noticed, driving to work today, that there was this loud squeak happening while accelerating. It almost sounds like an old belt, or how old brakes sound when they are to worn. I have no idea where this sound is coming from.
The only thing is it happens ONLY when the RPM's are 2k-2.5k. And ONLY while accelerating. Other than that it doesn't make that noise.
I've tried revving to see if the noise is there. I also tried while moving, to hold the clutch and rev match to that zone and still no noise. It only happens while in gear it seems.
Driving to lunch today I pulled out on the highway and accelerated hard. The Sonata didnt want to shift higher than about 4th gear (auto trans w/ the "slap stick" that comes standard. I laid off the gas and the car seemed to be running fine at that point. 1/2 mile down the road the car just died. I pulled over the car restarted fine. At this point it didnt want to shift well and died a couple times. I stopped for lunch. Afterwards I took it easy, car acted fine. Outside of work I accelerated hard again and the same thing started again.
View 10 RepliesI've had my car almost two weeks, but today is the first time I've driven it with the radio off. I noticed some ticking coming from the engine during acceleration, and maybe it's my imagination, but it seemed more pronounced with the ECO mode turned on. I know these GDI engines are supposed to tick at idle, but is it normal to hear it during light acceleration too? My oil level looks fine.
View 19 RepliesMy 2011 Sonata 2.4L GDI has already 76k miles. Spark plugs were replaced around 75K miles, Air filter was replaced. Fuel treatment was done several time since ownership, Intake CRC for GDI was used once about 2K miles ago. The car is doing good until recently. When I accelerate the car acceleration goes uneven. It is not like hesitating but you feel like the car is taking it in steps. Sometimes the first run in the morning, the car idle feels a little bit rough but that's only in the morning. It has been like that for a month now. What do you think it can be? No Check engine light, no pending codes and nothing major except that. I really suspect a bad upstream oxygen sensor (Air fuel ratio sensor). What do you think?
A look through the intake shows a very clean intake. No signs for any carbon deposit. A Hyundai dealer checked the car and told me there is nothing to worry about. Just told me to buy more Hyundai fuel treatment (AKA Chevron Techron) which was done and still I feel uneven acceleration.
I have a 2011 GLS with about 47K.
There seems to be an issue with acceleration around 50-65MPH as the RPMs will jump as if to hesitate between gears (just my assumption). Maybe driving style/conditions as I live in West-Central Florida?
I'm the original owner and we have two of the same vehicles.
I noticed twice yesterday when I was accelerating from an intersection, going into 2nd gear (or 3rd depending on how short 1st is) it feels like it slips into neutral and I lose acceleration. If I take my foot off the gas and coast for a moment then re-apply acceleration, it goes on as normal without any problems.
66k miles... Owned it for 2 years and have had no other issues and have only taken it in for oil changes.
Am I correct in assuming the ATF is supposed to be good for the life of the vehicle?
I recently purchase a 2011 Sonata. It sounds like there is a rattle in acceleration coming from the exhaust (passenger rear)
I had the just alignment professionally checked, and it's spot on, but it seems to pull to the left still.
I have a 2014 Sonata with 22k miles. I love this car but lately I've noticed valve rattle under acceleration. Brought this up with service tech and he said I'm not driving the car on long enough trips to keep it cleaned off. When I researched the GDI very little info comes up for Hyundai mainly vw and BMW. I guess what I'm asking is is the only fix for the carbon build up removing the intake and cleaning the valves manually or is there another way.
View 56 RepliesI have a Sonata 2012 limited version. Lately its been loosing power while driving. It will going around 60 for instance and as I am pressing the gas all of the sudden the rmp begins to drop and the car doesn't respond to the acceleration of me stepping in the gas. It is not until I completely get my foot of the gas and re-engange again that it will recognize it and continue accelerating. It will doing whether I am going 60, 40, 20 mph.
View 2 Replies11' Non-Turbo 2.4 with 145k Full Synthetic every 5k (Done me or provided to the quicky lube) Around 80K about 2 weeks after taking it in for an oil change my wife heard a ticking sound coming from under the hood. Pulled over and there wasn't a drop of oil on the stick. It started with about a qt every 1000 miles or so, now it's to the point that I have to put a qt in about every 3 days (1-200 miles)
We cannot see oil anywhere, last I checked the plugs had carbon build up but were not wet. (Recently) We also hear a ticking sound during hard acceleration and a good bit of black smoke coming from the exhaust.
We still owe 5k on it, it's our first new car and I'm terrified the thing is going to blow up before I pay it off. Tonight as I was about to get in the car with her I heard the clicking sound again but this time it was full (just added some yesterday). I have compression and leak down testers, know a little bit but I am nowhere near a "mechanic".
People are complaining about sudden acceleration with the DSG transmission. They had to up the warranty to ten years and fix cars too. After I read that I realized my TDI DSG has this issue but I just chalked it up to my driving. Sometimes when you hit the gas the car jumps B/C it drops a gear when it's not called for. I can't picture VWoA even entertaining this. Does the phrase "operating as designed" sound familiar?
