I have a Sonata, bought Sept '09/stick same problem, wife and I stalled a lot. I am 42 and have driven...hmm 12 cars of my own and many rentals (UK) ALL standard. This is the most difficult car I have driven to make smooth. At 17000km (one month ago) and 5th visit, under threat of going to Hyundai for next step in the complaints process,... "problem found with clutch/biting too low.." Clutch replaced under warranty!!!
Hope this helps. Write EVERYTHING down, note all stalling, don't give up, keep going back. Also I had the accelerator module replaced at 7000, didn't change anything.

vince17 hi i bought a 2010 sonata April 2010 and I am having the same problem brought it back to hyundai to get checked out they said nothing is wrong with it. everytime i stop on brakes it act like it dont want to stop and start shaking. i am also having a problem with my odometer. i have not gone out of town but 1 time and total miles were about 1000 including return trip miles. my car was in the shop for two months prior to the trip it went in the shop with 1260 miles came out with same mileage but get this within a week time my odometer said 2592 miles and that was before i made a trip out of town it jumped from over 3000 miles to over 7500 miles within a months time now its saying 11686 miles. I had my car 6 going on 7 months and 2 of the months it was in the shop. I was told something about the calibration might be defected. So have you had that problem or anyone reading this reply had this problem I would appreciate all the help

Greetings Zara,Clearly something is wrong with your braking system,there should be no shaking or lack of stopping power,go to another dealer at once.My problem is smooth acceleration,very very touchy gas pedal(folks tell me I will get used to it). The other thing I noticed all my other vehicles would promptly start to slow down upon taking my foot off the gas pedal(this I believe is known as "back pressure" from the engines comppression,)well Hyundai I think has figured a way to disengage the engine from deacceleration drag,keeping the car in a "coast" mode ,thus harvesting all fowarding motion to use less fuel(though brake pads must take on the dask of slowing more often)Again bring your car to another dealer(sounds like you have a warped rotor or your anti lock braking system is kicking in prematurely)Shalome, Vince 17

Our 2010 Sonota 4cyl Automatic is just over one year old a has been great but for two issues. The minor issue was oncoming drivers flashing their high beams at me when I was at low. I solved this by lowering the driver's side light just a fraction with no noticable loss of vision. The larger issue is the aformentioned "jackrabbit" starts. I believe this to be a combination of quick "tip-in" of the throttle, a soft return spring on the pedal and a low first gear. Since this is a "drive by wire" aka an electronic throttle I imagine this can only be fixed by a computer reflash. In the warmer months this issue is an annoyance. On ice and snow it's just plain dangerous. Dealer says no knowledge of a fix. I'm emailing Hyundai directly.

Greetings old guy,My dealer was going to clear the program so the computer can relearn my "driving habits"The dealer also said if someone else drives the car they can have an effect.I still can't pull away smoothly and perhaps I will be trading this car in .Normally I keep a vehicle way past 10 years but am no longer going to put up with this ,if there is a fix for smooth exceleration please tell me vince17

Hi Vince. Emailed Hyundai Canada on the 1st. Waiting for response. Will post. Didn't think about a learning mode on the computer. When pulling away from a stop in poor weather I put the auto into manual mode and move out in 2nd, then put it into drive. Works fine, but a nuisance.

Received response from Hyundai Canada today re 2010 Sonata . Referred me back to the dealer who had previously told me hadn't heard of a throttle issue and there was no fix. With Hyundai being such a progressive company I'd hoped for better.
