Engine stopped without warning at a red light stop. Was not able to start it up for several times.

- Mountain View, CA, USA

Vehicle has bad hesitation since 20,000 miles stalls, loss of power at times step on the gas pedal and car doesn't move, afraid to drive a new car that I pay for is crazy but afraid to get in an accident so I do not drive it. Hyundai keeps giving me the run around that the computer updates will fix this transmission problem but I have had 3 updates and it keeps getting worse and no one will do anything about it except take my money. These 7 speed dual clutch transmission have real issues serious issues that an cause a death if they lose power and get in an accident someone is going to get killed!!! the 7 speed dual clutch is not engaging in the 1st and 2nd gear and it causes the hesitation and stalling that all these cars are having and Hyundai knows it is a hugh issue so they did'nt put this transmission in the new cars they went back to the 6 speed shiftronic which was better...but leaves the people who bought these horrible models left in the dirt these cars need a recall asap I will not drive mine nor will I put my child in it thats said I pay for a car to sit in my driveway and no one wants to help any of us!!!!! I see thousands with the same issue as mine its not fair.

1/2 mile after starting my vehicle and driving approx 30 mph, my car shuttered and shook. Pulled over and it seemed to fix itself so I continued 23 miles to work. Was approx 39 degrees according to car dashboard. Leaving work 9 hours later, I drove approx 1.5 miles in stop and go traffic, speed no higher than 25-30 mph, crossed over rr tracks and the car shuttered and then shut off completely rolling to a stop. Threw on my hazards and the screen indicated I should put it in park and restart. The battery light and master indicator light came on. Car restarted and the lights disappeared. Went straight to Hyundai dealer. They attempted a 17 mile road test the next day after the car sat overnight and it did not repeat the issue. Nothing was stored in the computer system from when the lights came on. They have no explanation. Oil was changed and took car back at 5pm the day after the issue took place. Drove 24 miles to work today and it did not repeat yet.

- Warren, MI, USA

36,000 miles and the engine died without warning after proceeding through a stop light. Well maintained too. Was told they need to replace the whole engine with a refurbed engine. Don't like the idea of a refurbed engine that I don't know the history.

- Beverly, MA, USA

Blown engine, bought 2015 Sonata with 36,000 miles, certified used, leased car. Driving home about 35 mph, the engine made a loud clunking sound, thankfully I was in the right lane, I pulled off the street into a parking lot when all of a sudden the car engine blew. Had to tow back to the dealership where they are to replace the engine. Hyundai usa needs send out recall for the gti engine that is causing a lot of issues.

While merging onto a freeway the vehicle stopped accelerating and simply revved as if in neutral. I released gas and attempted to accelerate again with to result. I drove onto shoulder to avoid a rear end collision, shut the vehicle off, and attempted to drive again with a positive result. Shortly thereafter while driving on the freeway attempting to change lanes there was yet another failure to accelerate and the same issue occurred, a full RPM rev with no acceleration. The check engine light finally came on. I contacted the dealer with the error code that a code reader revealed and was requested my VIN. They then claimed that there is a recall and was told to come see a specific service agent. Nhysa website reveals no recalls for my vehicle. The issue is the variable charge motion actuator. I am fearing that Hyundai is remedying the issue in case by case basis and calling it a recall to avoid penalty.

The vehicle began making a knocking noise while driving up the mountain to big bear. No warning lights illuminated on the dash. Two days later while descending the mountain, the vehicle continued making the noise. No lights were illuminated on the dash. Then, while still on the mountain, there was a loud "pop", smoke could be seen in the rear view mirror, and the engine died; I coasted to the side of the road. The car behind me pulled over and the driver yelled that my car was on fire. Flames could be seen under the car. The fire spread and ultimately the car exploded, setting the hillside on fire. The fire department extinguished the fire and the car was towed away.

1/14/18 upon entering a 4 lane major road from a store parking lot, my 2015 Sonata would not accelerate. I let off and pushed the accelerator pedal, no response though the RPM's were revving. The check engine light came on. I pulled over, shut the car off, and restarted the car. The car seemed to accelerate ok after some initial hesitation. However, the engine light is still on and the car is accelerating up to 11 mph, in drive and reverse, on its own when the brake is released (no use of accelerator pedal). In addition, when in drive, the car lurches forward reaching a speed of about 5 mph as soon as the break is released. I see recalls for these engine issues on 2011-2012 models. Appears issue not resolved with engine recalls showing for mode years 2013-2014, it seems the engine issues are still not resolved for 2015. My car has less than 45,000 miles and has been serviced at the Hyundai dealership I purchased the car new every 3000 miles until my oil change time before last. The next service sticker was for a 5000 mile interval and when I questioned this, I was told the dealership was using a higher performance oil that didn't require changing prior to 5000 miles. I had the next oil change done at about 4000 miles. I am concerned I will be told there is nothing wrong with my car, my engine is going to seize, and I will be stuck with this repair expense.

I bought the car with 15 miles on it. Ever since I got it the car been starling. Engine lights comes on. I took it to the dealership and they said its a false code. The 2nd time they said its air filter.the 3rd time they said its body throttle. Today the car shut down while driving it, im at the dealership and they want me to pay for the same problem that jas never Geo fix. They blaming me for not taking it everytime it stalls. There is diferrent problem with the car that I don't stated. I'm really frustrated after for trip here at tje dealership and cant even found the problem. Hynday os ripping poor people off because they also come with an excuse.

While driving the car started to putter and then stalled while on the way to work. The vehicle engine is shot I am told by the mechanic I have used for 10 years now. Called the dealership about the issue and was advised I could have it towed in at my expense and have them look at it at my expense since the car is out of warranty. The dealership I am sure will say it is not due to faulty parts or any error on their part and I will have to have the vehicle towed again so $120 for towing and $79.99 plus tax for their assessment of the vehicle just to be told it is not their problem but I don't have much other choice.

- Suisun City, CA, USA

Bought this car brand new and at 20,000 miles it all started to go down hill. My car shakes & stalls hesitates bad loss of power almost causing accidents on a daily basis. I have brought it to the dealer 5 times for the same complaint even left it there for 9 days still not fixed I have a $398 payment for a car I am afraid to drive. I will not put my children in the car I am that afraid of getting in an accident. Hyundai does nothing no one can fix it & everyone has the same complaint I do all over the internet. These cars need to be taken off the road before someone gets killed!!! I pay for a car that I keep parked thats insane!!! my car is unsafe and a road hazard and no one is doing anything for any of these people that have the same problem as me. I have even brought video footage to Hyundai and they just update my computers which makes is worse half the time.

The contact owns a 2015 Hyundai Sonata. While driving approximately 5 mph approaching a stop light, the vehicle suddenly began to emit a grinding noise from the front end and began to shake. The vehicle stalled. The contact was able to restart the vehicle; however, because it began to hesitate, the contact pulled the vehicle off the road and turned off the engine. The vehicle was towed to Hyundai of chantilly Virginia (14848 stonecroft center ct, chantilly, va 20151; 703-480-9000), but the cause of the failure could not be determined. The vehicle had not been diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 20,000.

I was told I need a need engine because of sludge indicating that I hadn't had regular oil changes. The car is two years old and I've had five oil changes. They won't pay for the engine but I've seen that this is an on going problem for these cars. Not my car is smoking even worst. They did three of the oil changes and another company that's now out of business did the others and I can't prove it because it was independently owned...there is no way to check the records.they completed an oil consumption test because we were losing oil. The car didn't start smoking until June 2017. We had been complaining since we had the car because it always seemed at this it didn't have any get up and go. They said that was because there are three different car modes; economy (which we always drive in), normal and sport. We never believed that. A police stopped my husband yesterday and said we can't drive the car with all that smoke pouring out the back. What am I to do? the car is only two years old! it had a little over 4K miles when we first purchased it. They said an oil change was completed prior to us purchasing the car. We never had any warning light that our oil was low.

I drove 200 miles from my home to charlevoix, Michigan. While driving I noticed that the engine was making a 'whooshing sound' every time I accelerated. This happened at highway speeds and at normal city driving speeds. Rather than drive the car home, I took it to the closest dealership some 60 miles away and reported the problem. Car has a 2.0turbo engine. The inlet duct that brings air into the turbo severed at the point of attachment to the turbo. The technician at the dealer said that he could not tell if the duct melted or was cut. Other than oil changes, the car has never required engine service. He deemed the car unsafe to drive off the lot., he said in his write up that any object could find its way into the turbo because the duct is unattached. This would lead to total engine failure, and hazardous driving condition. The car has been at the dealership since Friday, october13,2017. I received notification from the dealer today that the replacement part is on national back order and that they have been told by Hyundai that there is no promised delivery date since no parts are in stock I suspect that there may be other customers who reported the same problem which would be causing the stock-out situation.

- Bloomfield Hills, MI, USA

Problems started with rattling noise from engine, and engine loosing power/surging. This was 2 years ago with 20,000 miles on car, and took to dealer who applied ECM update. Which if anything made it worse, and car started surging forward in situations like applying brakes when approaching red light. This has caused me to nearly rear end several cars, and pushed me out in traffic when engine surges unexpectedly. I have made several trips to the dealership, like many others always get the same answer 'we were unable to reproduce issue', and even went to another dealership to receive same answer. Car still has same problem, it happens frequently, and also happens when I have had friends with me or drive the car. So I'm not crazy, not doing anything wrong, and believe hyaundai is trying to wait for power train warranty to expire. Since I travel for work and now have 94,000 miles on the 2015 Sonata sport.

- Montrose, MO, USA

Purchased 2015 Sonata for son. Sonata started stalling out at low RPM, idling very rough. When it unexpectedly stalls out, very dangerous to brake, steer. Took it to 2 Hyundai dealers, both said car needs engine replaced, neither could tell me exactly why. Said engine is all gunky. First dealer said it was due to metal shavings in oil. Second dealer tried to blame us for poor maintenance, even though we have service records. Car has 80,000 miles. Paid $19,382 16 months ago, $5800 remains on loan and car is worthless. $8000 to replace engine. I am 2nd owner. Purchase from enterprise car sales, with 60,000 mile warranty. Also purchased extended warranty, but at 80,000 miles, we are over. I have owned 4 Camry and 2 Accord in my life. All have run and been sold at around 200,000 miles. Big mistake to trust Hyundai. Many recalls on Sonata engines 2011-14, but no engine recall on 2015...yet.
