While driving my 2012 Sonata (purchased at freeman Hyundai in irving, tx) it started to have loose steering then started to hesitate frequently. While driving it started to hesitate and a cyclic knocking noise from the engine ensued while attempting to accelerate. Drove to dealership and was told the steering would be taken care of. Was also told the oil had metal shavings which was effecting the motor. The car is under warranty, this is a known issue. The service department is trying to get out of the repairs because the oil changes were not done by them. Any subsequent engine failure could result in my car stalling, increasing the risk of a crash.

Hyundai break switch, Hyundai break lights, sunroof, air conditioning break switch gone out four times. Took to savannah Hyundai to be fixed. No fix as car continually does not accelerate in the middle of nowhere - on the highway or when getting ready to pull out in front of traffic - very unsafe. I have contacted Hyundai Corp concerning this issue since 2015. Savannah Hyundai service manager mike told us that we were not allowed to return for repairs because they got frustrated trying to figure out. Break light never works. Had this repaired 3 times. Savannah Hyundai put new sunroof on. Four months later it wont open or close. We have paid for everything over and over and over using our extended warranty and copays. Even if Hyundai or savannah Hyundai previously fixed something and it was even within 90 to 120 days that the repair was bad, they never offered to fix without charge. Always made us repay full deductible and costs.. car does not turn on air conditioning system intermittently. Trips get awfully hot. Sometimes starting up car and restarting fixes. Savannah Hyundai never able to fix. Savannah Hyundai has reported on two occasions that our car has serious electrical issues. They believe this is related to sunroof and brake light. This car has been having issues before 60,000 miles and stil lhas under 90,000 and same issues repeatedly. This car is not safe!!!!!!!!!!!!!!!!!!!!!!!!!! car is unsafe. Currently emailed david zukowski of Hyundai, other Hyundai outlets, message hyunda on fb. Unresolved.

Car could not start without pressing acceleration pedal this morning (03/30/2016). After pressing acc pedal and turning the key engine started. It repeated the same way when car was started going to home. Although, it took much longer to start the engine. Drove home and then took kid to soccer practice. On traffic light, when green light was on, I was turning right but car suddenly accelerated without control. I moved gear to neutral and RPM piked to at 2500. I have a video of it after I stopped on red light. Car has 71086 miles and is in "prefect" condition. Check engine light was on for couple of days but there was no mil code present. After I turned the engine off and then on, check engine light went off and no codes were present, not even pending ones.
Car was not driven for 7 days. First day, on a way to work, check engine light went on. On a way home, at green traffic light, I was making left turn, acceleration pedal was pressed and car accelerated as intended but after half a second acceleration pedal stopped working and car slowly moved forward only by inertia. Acceleration pedal was non functional, and engine was running at idle. I was able to safely stop the vehicle on a stop lane, past intersection, with engine still running and non-functional acceleration pedal. Then, I shut off the engine and started it again. Acceleration pedal was working without problem. Mil codes were: P2135 P0221, P2106, P0121 and P2110. Took it to the Hyundai dealership in new hudson, mi where some incompetent mechanic could not even diagnose what was the cause blaming the car battery. Car battery is holding charge, currently at 12.4V and alterantor is charging battery with 14.2-14.4V. Car starts without any problem and hesitation. There were no cars coming from opposite direction at intersection so we were not in imminent danger when acceleration pedal lost control.
My car is slowing down while I'm driving and in order to pick up speed I have to take my foot off of the gas and put it back on to accelerate. I am also having electrical issues which includes changing my brake lights several times every couple of months. The electrical issue also includes my check engine light, seat belt light, check tire light and truck light on when it is not open. The electrical problem is also affecting my doors and alarm system I.e. my car is currently only manual when it should be automatic.

The approximate failure mileage was 53,000. Updated 04/29/16

2012 Hyundai Sonata limited 2.0T car looses boost when started after being left unused overnight or cold weather. 8500 miles. Apparently, the wastegate is staying open. I give it gas and the acceleration stays flat like its all engine. This usually happens when being in a ramp to enter the highway. The car acceleration goes flat and revolutions go up to 5000 to 6000. Car stays at 50-6-mph. Car went to the dealer for 5 days and gave it back because they didn't find anything. Told them about the wastegate actuator sensor but no response. When looking in the internet about this issue, there is a page www.cargurus.com/cars/discussion-T41526_ds522751 where many people are complaining about the same issue and, the problem is, that the car doesn't lit the "check engine" light so the dealer cannot scan the problem. This is a very dangerous safety issue because you might get run over by a truck when going in the highway.
Email letter from consumer to the administrator re Hyundai's flouting of their agreement with NHTSA by refusing to honor the Sonata recall for sudden unintended acceleration. The consumer had placed the vehicle into park, with her foot firmly on the brake, when suddenly the vehicle violently lurched forward at significant speed and hit and broke a split-rail fence and post.
Cruise control will not set, accel, or cancel intermittently with daily use of the car. It works usually when you first start driving the car but not always. The cancel button rarely works at all and there have been instances when the only way I could cancel cruise control was by hitting the brake pedal. Several near collisions because of the failure of the switches on the steering wheel working. I've taken it to the dealer repeatedly to have it repaired and they say they can't duplicate the problem. I bought the car new and just recently had it at the dealership again and now they say they won't cover it under warranty and that it would be customer pay. Hyundai has a database showing when I've had it in to be looked at. Today's visit was at roseville Hyundai in roseville, ca (916) 677-3636 service advisor 7713 calden, christopher.

When attempting to accelerate the vehicle to get onto the freeway the engine lost all power. This incident has happened multiple times on multiple occasions, each time Hyundai and the dealership have failed to identify and fix the problem. Each power failure event has been a near accident. I am concerned for the my passengers and my own safety. The vehicle has received all regular maintenance, oil changes and recalls. A case has been opened with Hyundai customer support.
On Jan 26 my husband was driving home and the road conditions were slippery. When he went to apply the brakes, he heard a loud pop and the brake went all the way down to the floor and would not come back up. Luckily this happened around the corner, but by the time the car made it into the driveway the brakes were smoking. I had to have the car towed to the mechanic. We had to replace the front brake pads, calipers and rotors. Also the brake switch oem had to replaced. When all said and done the total cost came to $729.64. Can I tell you how disappointed I am in this vehicle?? this vehicle is only a 2012 my high beams don't work nor does the cruise control. I am starting to think this car is a real lemon!!! at this point I would like to know if the brake system has any recalls because my bill was extreme and should not have happened on a 2012. I do not have the VIN number on me at this time. Very very disappointed and have nothing good to say about this car!
Bought a brand new 2012 Sonata a couple of years ago, and the engine service light was illuminated last Saturday morning after I tried three times to start the car. On highway I had trouble reaching 45 mph, the lowest speed limit. It's caused by low fuel pressure. I did some online searching and found that Sonata 2006 had the recall of fuel pump failed prematurely. I can not believe the same issue is happening to their 2012 ones. Am I the only one who have this problem with 2012 Sonata? this particular issue is not covered under warranty. I called the dealer and made an appointment a week away. Obviously they have lots of cars to service. Ironically, I just received their recall letter on 2012 Sonata for their "inability to place the transaxle into the park position". have to rent a car because mine might get stranded anywhere at any time. Worst-case scenario: Rear-ended by cars that are driving at a perfectly normal speed.
Car accelerated suddenly and could not be stopped. I was in a parking lot and backed up to leave, accidentally hitting a storage container with my rear bumper. I put car in drive to move forward and the car accelerated out of control by itself traveling fast about 30 feet. I tried to brake but could not stop the car. We hit a fence, moving the fence about 5 feet and hit the car parked on the opposite side of the fence, smashing in the passenger side of the car. We had our seat belts on and were not injured but without seat belts we would have been thrown through the windshield. I do not feel safe driving this car anymore.
