Had motor replaced from a previous recall, 4days after this fix I noticed a rough idle. Went to numerous shops incld dealership was told by dealership that recall was done and any other repairs would be out of pocket. Problem has progressed from rough idle and engine noise to poor acceleration and mistimed boosts. As in when entering highway car doesnt accelerate very fast very long delay before boost intiates. Once at desired speed when slowing down car boosts without pressure to accelertator!!! now that winter has arrived, sporadically on cold start car idles even rougher and sounds as if it with shut off. When driving in traffic car idles rough then shuts off!! no power steering! no lights ! no power! this happened whilst car is in drive and in motion! I try to avoid hwys and night time driving when I can as im scared to death of this car. I purchased it used in dec2017 11 days later intial issues began with car loosing power. Now after issue was "fixed" by replacement motor same intermediate lost of power issues again but with the added boosting issue as well now.

"fire hazard" received an engine replacement under Hyundai engine recall, I picked-up the car on 09-13-18. I've had several problems occur in the last few months. One of the main issues is a fuel/gasoline smell inside the cabin and around the engine compartment. Now there is extremely strong smell of gasoline whenever I just turn on the ignition without starting the car. I also notice that there was a puddle of gasoline on the ground under the engine area. I read that some cars are catching on fire after Hyundai replaced the engines under the engine recall. My concern is for safety of my family. There is potential that my car may/will catch on fire. The car has not been driven in over three weeks. I've filed a complaint on 12-03-2018 with Hyundai motors(case # 13222827) but have not received any updates as of yet.

Turbo charger fails to engage resulting in the vehicle's dangerously minimal speed and inability to keep up with traffic flow. Acceleration is sluggish at best after replacing various turbo components.

Car seized at high speeds, brakes locked and eventually was able to get car to stop on side of the road. Noticed burning under hood around engine and starter. When taken to dealership, was told that the issue was due to engine recall. Called in and expressed concern with Hyundai that car caught fire. I am now seeing that Hyundai is being under federal investigation over the fires. I notified the company back in June of 2018 about this issue, and was told it was just the engine recall. Now that the company is under federal investigation, I feel the company lied to me earlier during my issue.

I currently own a 2012 Hyundai Sonata 2.4 in which I purchased from a dealer and the car is currently using oil. Under further investigation I have read up on the recall for the engines and see that many were replaced under a "recall" I contacted Hyundai recall support and they told me to take it to a local dealer in which I did. My car had the airbag recall performed and I asked about the engine recall in in turn the service manager told me that the engine had been "checked" by previous dealer but not replaced under the recall. The car has all the symptoms of the recall needing to be performed on the engine assembly but they refuse to help me because the dealer states its outside of the recall milage slot. I feel as if there is a recall on the engine as a safety recall that the engine should have been replaced by the previous dealer before it was sold from them. Instead I purchase the vehicle and unknowingly have a potential safety hazard for me and my family. I believe a safety recall is a safety recall. Shouldn't matter the milage. It's almost as if Hyundai is saying "well if it's made it this far then screw it" the vehicle is using oil and has metal shavings in oil

Sonata

  • 80,000 miles
Dec 2016 Sonata stalled out suddenly while being driven at 75 M.P.H. on a rural highway. The dealership took the car for three months returning it in March 2017 having, supposedly, replaced the engine per court order. Now, fall 2018 I made several attempts to determine what was wrong with my car now after if has been using excessive amounts of oil even after a routine oil change and has trouble with holding RPM normal while assening or descending hills. When the oil pressure light appears briefly for one minute it is only at the point when the dip stick shows no oil at all. The dealership diagnostic has revealed the need for yet another new engine, but the dealership refused to pay for the cost saying that they only provide a 12 month or 12,000 mile warranty on the replaced engine. I don't believe that they even gave me a new engine to begin with. They gave me one by engine in exchange for another bad engine and are trying to get away with not a "breach of implied warranty." All problems with my car go undetected by the computer and happen while driving at full speed.

On June 8th, 2018 my husband was driving down interstate 85 in charlotte nc going about 60 mph when the vehicle stalled. He coasted the car to the side of the interstate. He turned the vehicle off then tried to restart it and nothing happen and power was dead in the car. Then he saw smoke coming from under the hood. The doors won't open so he had to climb out though the sunroof to safety. He opened the hood and the engine was inflamed with fire. He called the fire department, they came and put the fire out. The reason I'm filing this compliant is because he could have been seriously hurtor killed if the sunroof was close. Hyundai has no explanation for why this is happening and my vehowas total lost. We also have pictures and a video. I can't upload the video so if someone contacts me I will email it.
