My daughter was driving on the highway in the 2nd to left lane about 65 mph, check engine light was on and all of the sudden she lost complete control of the accelerator pedal. She say's she pushed it all the way down to the floor several times, no pressure, no control and obviously slowed down. She moved over to get to the right shoulder to stop and see what is the issue, luckily the brakes worked (hard pedal), but many cars were dodging her trying not to hit her. She didn't get in an accident, but sure close to being in one and high speeds. Frightening to say the least. I has about 87,000 miles on the car. I am still concerned if I put another engine should I worry about this happening again? it could happen again unless it's recalled and the problem fixed! I am just glad she didn't get seriously injured or killed. I am very concerned knowing that this could happen to anyone with the 2011-2015 2. 4l engine. I tried to be proactive therefore I'm posting this complaint for others. I guess it takes collateral damage of people losing life for car companies and the wonderful federal government to take notice. Beware most 2011-2015 hyundae Sonata cars have this problem from what I am told.

Vehicle starting shifting hard, then while driving approximately 45 mph, the car fell out of gear into "neutral". Pulled over. Vehicle ran fine for about a week. Vehicle then continued to shift hard and the check engine light came on. Took to dealer. I am the original owner. Was told it was two selenodes and wiring harness. This repair lasted 48 hours. Was repaired under warranty although they said it could be my driving habits.

I had a minor fender bender ( a person hit me and took off) 1 block later the engine died. It was taken to the shop where I was first told it needed a new battery and a starter. Battery was only 12 months old and starter was not a problem. I had it towed to Hyundai and they told me the engine seized from sludge and water. I I dont even have a sprinkler system for water damage and we are in a drought and the oil was changed a few months ago. I had read about the seized engine issues on this model but Hyundai says that is not true. I pointed out to them that no oil light came on and no check engine light came on. I have had no problems with this car until this happened. They refuse to do any thing about it but are willing to charge me $6700. 00 to replace the engine.

While driving the check engine light and esc light go on simultaneously. When this occurs, the car goes into reduced power mode ("limp mode") and you are not able to drive above 15 or 20 mph. This is a very dangerous situation, especially when driving on the highway. This is a known issue with Hyundai in which they issued TSB #'s 09-FL-003-2 and 10-FL-010. The TSB's address a faulty throttle position sensor which is to be replaced with a new one with different settings than the original. One the part is changed, an update to the electronic control module is required. There are numerous accounts of this incident happening. How can a flaw of this magnitude not warrant a recall?.

I was driving home from work when all of a sudden my check engine light came on and I started hear noises coming from my engine. I pulled over somewhere safe and eventually had to get it towed to a Hyundai dealer. I'm not the original owner of the call so the dealer tells me I cant used the 100,000 mile warranty. I have another warranty company who wants the dealer ship to come to a final decision as to why my engine stopped working. There was no sludge in my oil pan but there us metal which obliviously means something messed up on the inside. Hyundai is telling me under no circumstance will they further investigate what happened to my vehicle and wynn is telling them they will not pay for my vehicle unless they have the specific reason as to why a engine that only had 86,000 miles stopped working. My husband has a 2007 Honda civic that has 210,000 miles on it and yet my newer car dies out at only 86,000 miles to me this doesn't make any sense and I'm getting the run around on all ends. I don't have 6000 dollars to pay out of pocket expenses that is why I got the warranty in the first place. My engine shouldn't have gone out and with no warning!!!!!! so now I'm stuck without a car, paying a car payment for a car I cant drive, and no way to get back and fourth to work this will cause me to lose my job and not be able to care for my family something has to give.

This is the second 2015 Hyundai Sonata which had computer problems. The first one purchased in July 2014, Hyundai took it back in Dec 2014 because of the computer problems. The second picked up in Dec 2014 currently has approximately 2900miles with the same basic computer issues. Both vehicles when travelling from about 40 to 65mph the engine's computer system would cut the speed down and lose compression to approximately 20mph to protect the vehicle from some kind of engine damage. You would be forced to get off the road and shut the vehicle off. Once the engine was off 5 minutes the engine would start up, the check engine/anti skid lights would stay on so that the dealership could see what codes were causing the problem. The first vehicle was assigned a case# by Hyundai -case# 6788232 and was finally taken back by Hyundai in Dec 2014 after being out of service for well over 35 days due to the continued computer problems. The replacement vehicle recently had 3 incidents while travelling at approx. 65mph the engine would go to 20mph without warning. The only exception was that when I restarted the vehicle the check engine light would remain on until I turned off the vehicle. When I restarted the vehicle the check engine light went off leaving me in a difficult position when bringing the vehicle in for service, the computer didn't store the event to verify the problem. The dealer said if it occurs again to let them know and they would contact their technical hotline. The service dept knows there is a problem since they went through this with me on the first vehicle, that's why they took the vehicle back. I established a new case file 7799545 on 4/16/2015 with Hyundai consumer affairs.

At 11:38 am, car suddenly lost power while in middle of intersection, all the symbols on the dashboard lit up, pushing on throttle had absolutely no effect on cars movement. Car would go forward at idle speed only. Received a message on navigation screen and an email saying ?a possible condition with your engine control system has been detected. Hyundai recommends a full system check soon. To schedule an appointment with a Hyundai dealer, say service link when asked to say the name of a service. Pulled to side of road, turned off engine. Restarted engine, only check engine light was on, but acceleration still rough.

I was making a right turn when the vehicle stopped. I could not restart it and had to have it towed. When the vehicle was inspected I was informed that the engine has seized. There was never any oil or check engine light that came on. The oil was changed when it should be. There was oil in the engine. Since the warranty was up I had to come out of pocket for an engine. .

We were driving highway speed when all of a sudden the cars check engine light, esc light came on while in the middle of traffic and the motor completely shut off causing no steering or any control of the vehicle, was able to coast to the side of the road and tried restarting the car with no luck. Called the dealership immediately and they stated it had done that to the previous owner but was not warranted to be fixed, but yet we only purchased this car 6 months ago. Sat on the side of the road trying to figure out what to do, when the tow truck came by and scanned in which I got the following codes: p2106,p1295,p2135. Its a sensor on the accelerator pedal and causes the car to shut off immediately because it cant respond to the throttle body. This is very dangerous as we could have been rearended and seriously injured. Please contact ASAP!!!!!!.

I was pulling up to a stop light and my car made a jerking motion, as it had did one day prior as well. I looked at my dash and the eps light, battery light, check engine light, and one more light came on. I tried to drive the car forward and it began to roll back. I turned the car off to try and restart it, but the break would not push down for me to turn it back on. The car was towed to a dealership where I showed two service technicians the photo of the dashboard that I took, and both said that my engine had cut off. They kept the car overnight and drove on it to try and recreate the problem, along with running multiple tests, and nothing showed up.

I started the car and it shook some and check engine light came on. I checked oil and it was 2. 5 quarts low. Filled the car with oil. Drove it to the shop to have a oil change done on it. The shop changed the oil and I drove the car home. As I was driving it home the car started sputtering and clattering. The car stalled. Towed to shop where mechanic immediately checked oil. It was full of oil. The mechanic changed the sensors. After changing the sensors the check engine light went off but the motor is still knocking. The mechanic confirmed the engine has been seized. The engine needs to be replaced. I have read on the internet that the 2011 engine is known to have major problems.

My 2006 Hyundai Sonata has the check engine and esc lights come on, then the car wont accelerate as well as the rpms will not move. The car coasts like its in neutral. And today was the last straw when it decided to do it while going down the road instead of just when beginning the drive.

Case no. [xxx] I purchased my 2007 Sonata from the denville, NJ dealership in may 2007. With only 38,000 miles on odometer I had the scare of my life¦. Driving on the highway, the engine died, and I lost all power. The ¿¿check engine¿� light came on. Thankfully, I was able to pull to the shoulder of the road and safely stop the car. After 2 minutes I tried to restart the car. It started and I drove it home with the check engine light still on. I checked that all fluids were ok. Next day driving to work, coming down a long grade, car engine died and again I was fortunate that I did not get into an accident. I brought my car to a aaa service station and reported the problem. They checked and informed me that the problem is due to the throttle position sensor,(tps) which they found a tech service bulletin describing the symptoms and condition. They gave me a copy of said bulletin. They noted that even if they installed the part, I would have to have a Hyundai dealer perform ecu software update. Therefore, I brought the car to the dealer and had them make the repair. I expected that this would be a ¿¿recall¿� by Hyundai, as failure of this part could be life threatening, as it was in my case. They said they could not honor any warranty service and I was charged $252. 24. I requested and received the replaced part. . I am rasked Hyundai motors of America to show good faith to a loyal customer, by reimbursing me for the costs associated with this known failing part. . Their response:" TSB are not recalls. Dealers are made aware of these and are asked to perform them on affected vehicles when they come in for other service. I vehicle outside of warranty, then the repair is an out of pocket cost to customer. They apologize for the inconvenience this may have caused. " they refused to reimburse me saying this part was not a recall. How outrageous of them!.

Under normal driving, vehicle suddenly sputtered a bit and then the check engine light and electronic stability control light came on. The car then would barely move over 15-20 mph. We found out that these are the classic symptoms of a tps issue, for which Hyundai issued TSB 10-FL-010. We have had the vehicle at the dealership for all of the recommended repairs from that TSB twice with no resolution to the problem. My concern is that this problem occurs randomly and without warning. At least twice it has occurred on the interstate, and I felt we were lucky to get off to the side without another car running into us. I am extremely worried that the next time this happens we won't be as fortunate, and someone can be seriously hurt. This is also a very common issue with Hyundais. Frankly, I would not be surprised if someone has already been hurt because of this. I am also surprised Hyundai has not issued a recall or found a better solution to this problem. I believe this is a very serious problem and urgent safety issue. In fact, we would like to get rid of the car, but we cannot afford to buy another car, nor am I too keen on inflicting this problem on some other unsuspecting person thinking they are buying a good, reliable car. Please try to pressure Hyundai to come up with a better solution.

My car started getting erratic idling and then the engine light started to turn on. I got the spark plugs and spark plug wires replaced and then it mild down after around 1wk after, then the erratic idling while on drive or on reverse started again. Left it like that thinking it was maybe the fuel pump or something like that. Had my brother that is a mechanic check it and said he found the spark plug wires out of sequence, but after he made sure all were the correct order the same problem started again, same erratic idling and this time it really did feel like sometimes loosing power. It has gotten worse since then that I was driving, don't recall the mph, but it must of been around 50 - 60 mph cause I was on the freeway. The whole engine sporadically, in less than a split second, turns off then on. All the electric panel and the front dashboard and the whole car's electrical system turns off/on in a "blink of an eye". It made the car make an erratic and sudden stop, like if I had put the brakes completely or the engine just stopped that split second. Then it went back on and still driving. After that it did it about 2 more times like around those mins I was driving, about mins apart. After this happened, it's been getting worse and now the power shuts off completely and I have to drive to the side with no power on car. Then suddenly gets power again and I just start it again. I've checked the cables of batteries and they keep telling me I can't get the car checked for codes cause the engine light keeps getting reset since it looses power completely and they can't get any codes unless the engine light is lit up. Sometimes turning signal or putting the brakes or lights on make it stop or loose power completely.

I drive the Hyundai Sonata hybrid. The first time the problem occurred at approx 9800 miles, I was driving 60 mph on a highway when the vehicle lost battery power and an alarm sounded, and then a signal indicating to "check charging system. " I immediately took the vehicle to my Hyundai dealership where they were aware of the issue, but did not know how to fix it and suggested I just simply turn off and then restart my car. It happened two additional times, one while approaching a stop light, and another time while I was stopped at a stop light. The last time it happened, I could not get my vehicle to reset by restarting once. I had to shut the vehicle off, then attempted several times to restart. The 4th time I tried to start it, I was able to do so sucessfully. I did notice the last time it happened, the engine light remained on even after battery power was restored. I am taking it back to the dealership tomorrow and demanding a solution. This is just too dangerous to lose power in high-speed traffic, and the problem seems to be occuring at all speeds.

Engine can easily become hydro-locked in heavy rain and road splash back from other vehicles due to the design of the direct air intake of the Sonata hybrid. With its design, it does not have any water baffles to prevent water from entering the air filter and once it enters the air filter box, there are no drain holes for it to drain out. This forces the water through the engine as that is the only way for it to get out of the filter box. When the engine stalled, no electronic control warning lights were illuminated and the car remained in the “ready� state. This could lead to damage of the hev system and battery pack. Per the technician servicing the car, they stated that the hev warning light only illuminated when the hev battery reaches 15% charge (the point at which they have to replace it), this contradicts with the owner’s manual as well as counteracts the purpose of a warning lamp. Due to the nature of the design where the computer controls when the engine start/stops, the engine can damage itself before preventative action can be taken. For example, when the engine stalls due to water ingestion through the air filter and the oxygen sensor determines it cannot compensate, the engine will stall, but before the situation can be rectified, the computer attempted to restart the engine causing it to become hydro-locked. With my experience, I am convinced that the design of the car is flawed and is unreliable to drive in a heavy rain scenario which leaves it unusable several times a year. I have owned several hybrids in the past (2001 and 2005 Toyota prius) that I operated through the same conditions as your vehicle and I did not experience any problems with them. Additionally, with the Toyota, when the engine stalls against the computer’s control (e. G. : running out of fuel), the hev and engine warning light both illuminated and the “ready� light was DE-illuminated.
