told the Hyundai dealer 2 years(March 2021) ago that I was concerned about my oil light flashing periodically between scheduled oil changes. No action other than oil changes and one time they added a couple of quarts "no charge" as it again was low. Continued to change oil more often than necessary and the frequency increased. Multiple other car repairs have been happening and the oil now has to be added weekly to maintain proper amounts. Had to change spark plugs 2 times with in 5 months and now another engine light came on today 11/15, and when I check the code at a parts store I was told is was a P03001 and P03002 which was something to do again with the cylinders misfiring. Everyone I have spoke to says this is an engine issue and it is under recall. I did place a claim with Hyundai Care USA after being told by the dealer that it would be better if I did this instead of them. The assistant manager also confirmed that the engine is covered 100%. I did this in September after the second repairs. The Regional Manager finally called me back and indicated he agreed about the problem needing to be resolved and would call me after he spoke to the dealer in a day or two. It has been over a week and no one has called. I keep leaving messages. I now have the same error codes, it is November 15 and the spark plugs were all changed less than 2 months ago for the exact same reason. I have been stranded and at times when I accelerate onto traffic the car will not respond. I do not use the interstate anymore as I cannot predict when the car will slow down and not get enough speed and cause an accident. I only drive to work and back right now. I was given this website by the employee at the parts store along with some information concerning P1326 codes and they are engine related. I will upload the most recent repair receipt.
2015 Hyundai Sonata acceleration complaints
Page 2 of 3: complaints 11 to 40 of 61, newest first, as owners wrote them.
The contact owns a 2015 Hyundai Sonata. The contact stated while driving approximately 3 mph and entering a driveway, the vehicle accelerated independently and crashed into a metal gate. The contact stated no warning light was illuminated. The contact stated no air bags were deployed. The contact stated no one was injured nor sought medical attention. The contact did not contact the police department nor filed a police report. The vehicle was not drivable and was left at the locations of the incident. The vehicle was not diagnosed or repaired. A dealer was not contacted. The manufacturer had not been informed of the failure. The failure mileage was approximately 63.000.
My daughter was driving on the interstate when the car went into limp mode and the engine light was flashing. We had it towed to hyundia dealership where they did an engine update. Had it for 3 months when it did the same thing to her again. Had it towed again to same dealership where they are telling me it needs a new engine.
The engine stalls out randomly. This is the third time it's done it. The first time was while I was exiting the freeway on March of 2021, which I thought was a fluke. The second time was July 19th and the third time was July 30th. There were NO warning lights or messages. Took it to the dealer and they said that everything came back fine with the engine. They confirmed that the RPMs were too high when it was in a parked position and the engine was on when they first took it in. They suggested I replace the starter. I'm going to a different mechanic for a second opinion. The car was in motion with my foot on the gas pedal when it started to stall. There is no way that it is from a starter.
Driving at 55 and the engine blew. No warning, no check engine light, no sign of anything wrong. Power steering loss, limo mode activation. Almost rear ended during catastrophic failure. 111,000 miles
Major oil consumption going on for years. Took in to dealer two years ago, they know there is a problem. They told me I could spend thousands of dollars to tear it apart to find out what is going on, and also told me to call corporate. I got no where with either, even though they recalled the engine in other Sonata cars, just not our ECO model. Slowly started having throttle issues at 4 to 5 year mark. Informed dealer service center that it wasn't moving like it should when gas was pressed. Now, the car is having major problems with acceleration. Barely would go in reverse, drove 1.5 blocks, speed not matching to throttle, press on gas, barely moving from a stop, going really slow, had to turn around and take back home. Our problem with the car is the same that others are complaining about. The car is not safe for a 7 year old car that started having problems at the 4 to 5 year mark.
The contact owns a 2015 Hyundai Sonata. The contact stated that while driving 40 MPH, the vehicle failed to accelerate while the check engine warning light was illuminated. The vehicle was towed to an independent mechanic where it was diagnosed that the throttle control module needed to be replaced. The vehicle was repaired however, two weeks later the check engine warning light illuminated. The vehicle was taken to the dealer where it was diagnosed that the Voice Coil Motor (VCM) needed to be replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 127,828.
While going home on highway 95 at approximately 70 mph. The vehicle stalled almost causing many accidents. Thank goodness I steered it on the shoulder and it will not restart I had to call for a Tow. This was the 3rd time this happened. The first time was approximately a month in 2015 after my purchase it stalled on the highway. Again, in 2017 it once again stalled on the highway while I was driving. The dealership has told me on all 2 previous occasions that they had fixed the problem and it wasn't going to happen again. Here we are in 2022 and it stalled again. Why can't they just replace the engine? This is the second week and my car is still in the dealership which they are saying they don't know what the problem is smh.
Sonata started having problems with less than 50,000 total miles. The accelerator is flawed and the vehicle cannot keep speed when traveling uphill or get to speed efficiently. The vehicle jerks for a few seconds when pressing the gas and the engine revs but the vehicle does not accelerate like it should. This has almost caused me to have accidents multiple times when pulling out into traffic. The check engine light came on when this started occurring and has been on ever since. I'm having the hyundai dealership take a look at the vehicle and see if there is anything that can be done.
My engine light has been on for over one year. I took it to the dealership to see what was going on and to get an oil change. The dealership stated that there could be a variety of issues and that they would turn the light off and when it came back on to bring it back to them. The staff was not the most professional so I opted to not take it back unless there was a significant issue. My car constantly accelerates when I am on the brakes at a light and then when I let off the brakes, the car accelerates before I put my foot on the gas. I recently backed out of my parking space and without my foot on the gas, I bumped into a neighbor's car. There was no damage to their car but my car has a dent in it. Everyone is safe and fine but this could have been way worse if I was in a parking lot or on the road. The car does not accelerate when I put my foot on the gas on the highway either. I have had some close calls getting onto the highway because I can press the pedal to the floor and not get the speed needed to go fast enough. I am making plans to take it back to the dealership and report my dent because this acceleration issue is very annoying when driving and I know that it is dangerous in situations where I should be able to shift the gear and not be moving fast enough to get a dent. I hope Hyundai really looks at this issue and helps us out. Thank you.
The contact owns a 2015 Hyundai Sonata. The contact stated that while operating the vehicle, it would not immediately accelerate when pressing the accelerator pedal. The check engine light would remain illuminated. Also, the vehicle had experienced unintended acceleration. The vehicle was taken to an independent mechanic who reprogrammed the engine software but the failure continued to occur. The local dealer was notified of the failures. The manufacturer was not yet contacted. The failure mileage was 50,000.
I'm really at wit's end with what is going on with my car. My car is currently at 104K, its a 2015 Hyundai Sonata Sport. A beautiful car with an abundance of serious issues. I've had trouble with my car accelerating for over a month and I've taken it to at least 5 mechanics who have troubled shooted with no success to fixing the issue. The problem: my car hesitates significantly when accelerating and sometimes when it's can't shift gears and I'm easing my foot on and off the gas pedal, it begins to shake while attempting to accelerate. I try not to put the car in sport mode but sometimes this mode is what helps the car shift gears but I don't think this good for the car. So far I've tried changing all of my spark plugs and coils replaced, fuel injectors cleaned (dealership), transmission fluid changed and ECM updated (dealership). Also, the Hyundai dealership diagnosed the issues as an engine problem (intake exhaust and timing chain + tensioner) --- cost of all these things almost $4000!! I just don't understand why the check engine light is not coming on -- which is hinting at the local mechanics that it might be a transmission based issue. No the check engine light has not come on but the car drives really poorly. I'm taking it to a transmission shop and hopefully going to get some answers as to what is going on. This issue is absolutely frustrating and now I'm just looking for real direction by waiting to see if the engine light will come one and throw a code
I was driving to work as I normally would from the University I attend. About half way to my destination the check engine light illuminated and right when I was about to find a safe place to stop the car abruptly stopped in the middle of the Highway and stalled on one of the most dangerous highways in the U.S. being US I-20. I almost immediately got hit from behind however a few vehicles behind me did get involved into an accident due to the my car stopping abruptly with little warning. I called hyundai immediately and asked for a tow driver however the wait time was excessive and I had to go to work. I was able to start the car after 20 minutes, but it was in limp mode and I pulled off to the side of the road and had to uber to work. The next day I had got a tow truck to pick up my car and take it to the dealership where they said the car had accidentally triggered the knock sensor by mistake and replaced it free of charge. However the very next day it happened again after driving about 30 miles. And I took it back to the dealer they offered the same thing a replacement sensor. When I did some research and the car actually needed a new Engine after a recall had been placed. Hyundai refused to replace the engine after the knock sensor deployed. This is Hyundai's issue and it needs to be addressed. I was forced to put the car on the side of my house for the time being and get a rental until I could afford another vehicle. This is very disappointing from a consumers point of view. I filed with the extended warranty campaign TXXC and got denied due to the amount of miles on the vehicle. However there was no warning before the engine failed. The car was very well maintained and had regular Oil changes with full synthetic oil every 5k miles. No precursors to the engine failing occurred, like a knocking or jerking or anything. This is an issue that hyundai need to address. I am very disappointed. Campaign reference number for my case 17507525.
I have been receiving a 'safety stop. Check hybrid system' warning multiple times. I have taken it to hyundai multiple times telling them of the issue. They kept telling me no issue could be found. The last instance they updated the software in the car in what appears to be a hail mary to say they did something. Last night I was traveling I was traveling on the highway at about 60 MPH. The car started dinging and gave me the warning error attached. The car completely lost power and only allowed me to coast. I was lucky enough to barely able to get myself into a location of relative safety. I parked the car and restarted it and was able to drive once again. This continues to be an issue, extremely unsafe, and hyundai cannot give me an explanation or fix the problem. This is unacceptable and almost lead to a massive accident.
Vehicle started slowly cranking for a week or so and then while driving in a 55mph zone, speed suddenly dropped to 20 MPH with choking to the point of pulling to a safe area and having car towed 11-4-2020
When trying to set my cruise control a message pops up on my dash saying scc conditions not met.
While driving on a busy four lane I entered a turn lane to cross traffic. Immediately after I engaged the accelerator the vehicle lost all power and steering, with a alarm stating 'hybrid system warning-do not drive'. One vehicle narrowly missed hitting my car, (as it completely lost all power and steering and left me stuck in the middle of on coming traffic). Researching today I see this is common between 2012-2016 especially. This is a very dangerous situation that was narrowly avoided.
Cruise control does no always engage
While driving down highway car began to smoke from tailpipe and began to lose acceleration while driving on highway. Vehicles check engine light illuminated. Took vehicle to nearest auto part retail store for diagnostic testing. Error code p0014 came up along with 2 other codes. Took vehicle to auto repair shop. Advised the exhaust solonoid had to be replaced along with spark plugs and gaskets due to burning from theta 2.0l turbo oil feed line. Car not drivable back to houston where I reside. We had to find additional time to stay at hotel and well as pay for transportation back home. My car is still in san antonio. Recall was repaired less than 6 months ago and car now has the same issue.
Driving home and all of a sudden this alert goes off. Brake system warning, pull over now. Check brakes. Car slolws shuts off and I'm stuck on the road. Had to get a tow and now car won't start. Shows same warning when I try to start it.
I was driving to work friday 12-6 at approx. 7:24am and the check engine light comes on and flashing. I then pulled over to see what was wrong and I turned the car off and back on the car will then only accelerate to 10 MPH then slowly accelerate but will not go past 63. I was able to drive it back to a mechanic who then diagnosed it and stated it was a p3126 obd-ii diagnostic powertrain (p) trouble code description p3126 engine trouble code is about exhaust gas recirculation sensor b circuit high. Reason for p3126 code the reason of p3126 obd-ii engine trouble code is engine oil temperature sensor malfunction. P3126 code on vehicles with electronically controlled automatic transmissions, the 3-4 shift solenoid is responsible for actuating the hydraulic circuits to activate clutches or bands that change gears inside the automatic transmission.contacted hyundai and justin asked me was the check engine flashing I advised him yes. He said it was more than likely a recall. He made me an appt for tuesday 12-10 @ 7:15am. I proceeded to drive my vehicle to hyundai and I was told it's not a recall and they are going to charge me $175 just to diagnose the problem. I drove it back to my job in flowery branch ga and contacted geico to tow it back to my house.
Tl* the contact owns a 2015 hyundai sonata. While driving various speeds, the brake pedal was applied, but the vehicle failed to respond and continued to move and idle. There were no warning indicators illuminated. The vehicle was towed to an independent mechanic who stated that the brake sensors and throttle body needed to be replaced. The vehicle was repaired. The local dealer was not contacted. The manufacturer was contacted and provided case number: 16052684. The contact requested reimbursement, but was denied. The failure mileage was 35,137.
Scc refuses to come on saying scc conditions not met. When it does come on it turns off by itself saying scc conditions not met or check scc radar. Sometimes does not detect vehicle in front of me. Goes in and out between detecting vehicle in front of me and not detecting it. Randomly says check scc radar. Does not stay engage, turns off by itself, will not turn back on. The car was in motion on a highway.
Engine hesitates to put out power when taking off from a stand still. Transmission upshifts instead of downshifting when pressing pedal pedal 50% of the way. These problems occur in city driving.
Around 25000 miles, after start, strong engine vibration with no power - about to stall. Dealer changed variable charge motor after 5 occurrence of similar situation. After few months at 29000 miles, 2015 sonata se (2.4l 4 cylinder engine) lost power and stalled in the middle of city street, while driving. Could have caused big accident if I was on highway. Car was unable to restart. Towed to dealer and replaced accelerator position sensor. Could be related to issue with 2011-2014 sonata engine recall since my 2015 sonata uses almost same theta-ii engine.
My 2015 hyundai sonata was purchased brand new, and have had multiple power/acceleration issues; however, the most recent happened on march 19, 2019. While driving on a street (evening time) with the speed limit of 45, my car started to sputter/jerk back and forth, abruptly bringing my car to a speed limit of under 15 mphs. I tried to accelerate, but the gas paddle was unresponsive. This a major hazard and extremely dangerous. This is a known issue, and hyundai corporate office is aware (I called after the first incident), and is not doing anything to rectify the issue. The federal safety agency need to make the manufacturer accountable, by reason of the numerous complaints about the same issue. I was close to being rear-ended, and if nothing is rectified, it will cause an owner to be severely injured.
Tl* the contact owns a 2015 hyundai sonata. While the contact was pulling into the driveway with the brake pedal depressed, it independently accelerated without warning into a two-car garage. The contact attempted to stop the vehicle, but was unsuccessful. Prior to the failure, the vehicle surged forward without warning, but the contact was able to maintain control of the vehicle. During the second failure, the vehicle crashed through a double garage door and partially into a wall at the end of the garage. The air bags did not deploy. Police report number: 18-0018173 was filed. There no were injuries sustained. The vehicle was towed by the contact's insurance company to a facility for inspection purposes. The contact stated that the entire front end of the vehicle was damaged. It was undetermined as to whether or not the vehicle was destroyed. A dealer and the manufacturer were not made aware of the failure. The failure mileage was approximately 41,000.
On highway 70mp sonata loses all power towed to hyundai dealership.3 days letter knock was to blame an wiring replaced.15 minutes after picking up sonata an reaching speeds of 70 again on highway sonata loses all power again almost causing pileup in rush hour traffic gain sonata is towed back to dealership. Dealership confirms only parking lot test was done not highway after replacement even knowing the wide spread engine failures / issues sonata is having an catching fire. This is serious an life threating you lose all control no power no warning !!!! At high speeds.1/8 sonata currently at dealership
P0010 code and p0011 can hear a metal grinding noise when accelerating also fluctuating rpms. I keep immaculate maintenance and take excellent care of it. Absolutely no idea how but parked car everything was normal, started car next day and rpms shot high and light came on. They reset light and say nothing wrong but this keeps occuring. Highly upset as I have absolutely loved everything about this car until now.
At around 80,000 miles car started going down hill. It hesitates to take off from a stopping point. It shakes sometimes when about to accelerate and it doesn't accelerate very fast anymore gets up to about 1800-2000 RPM before it actually picks up speed.
