This vehicle is consuming large amounts of oil. Up to 3 quarts and 1,000 miles causing the oil light to come on. Hyundai did an oil consumption test with failing results. Due to this they did a deep combustion chamber cleaning. The car still continues to burn excessive amounts of oil. I am told that this does not qualify for the class action lawsuit because it is piston related and not rod bearing related. There is a burning smell coming from the vehicle that does not smell like burning oil. I am highly concerned that the vehicle is going to catch on fire yet Hyundai refuses to do anything about it.

While sitting at a stop light the vehicle suddenly would not accelerate and would not rev the engine above approximately 2000 rpm. Then the check engine light began to flash. I was nearly rear ended because the vehicle just would not accelerate.

This is a follow-up to former Complaint #11450586 (05-Feb-2022) and confirms that both my local Hyundai Dealer -and- Hyundai Corporation (USA) are aware of this diagnosable- and fixable problem-?"but they fail to issue a recall. In fact, a Service Advisor at my dealer expressly vocalized that 1) he himself [excluding his colleagues] has seen at least -2- of the same incident recently; and that 2) Hyundai Corporation (USA) issued a -??(service) bulletin-?? about the problem. PROBLEM: The vehicle: 1) has a high idle; 2) shows a solid-illuminated CEL/emissions light; 3) severely resists braking-?"my vehicle would even slide through stop signs; 4) fails to -??pick up-?? normally; and 5) drives unsteadily. This is at minimum and is my experience from both last week and from the original report on 05-Feb-2022. As explained to me today (28-Mar-2022) by my Service Advisor, there is a known fault with a component within the engine (Powertrain). Specifically, there is a tube that is-?"as I understand-?"meant to be FREE of fluids. However, and per the Bulletin, the tube becomes full or over-filled with oil from the engine (Powertrain). Further, the Advisor suspects that changes in temperatures (e.g., such as the teens back in Feb 2022) causes that oil/fluid to expand and contract, causing (further) damage. This issue must be remedied by Hyundai Corporation (USA) immediately because it is a *SAFETY RISK.* My Dealership emphasized severely how unsafe it would be to drive the vehicle off their premises without a repair. I-??m fortunate because I-??m the original owner and thus am covered by the 10 yr/100,000 mi Powertrain warranty. PLEASE SAVE LIVES FROM THESE -??FLYING-??, UNCONTROLLABLE CARS BY MANDATING A RECALL. * will provide Dealer-??s documentation once vehicle is repaired. I was advised to wait 2-8 wks for parts and repair.**

My car has been stalling, hesitating and sometimes I feel the engine shake when using the gas. I brought my car to the dealer to have the most recent recall fixed and asked them to diagnosed what else was going on with my car. They told me the stalling was just due to the recall. However, the very next day my car was acting up again. Additionally, the car at times will accelerate when I am not pressing on the gas. I don't think I need to go into detail about how my safety and the safety of others is compromised when you have a car that accelerates on its own. Lastly, there is no check engine light on. This has been ongoing for several weeks.

- Owings Mills, MD, USA

Car has been consuming an excessive amount of oil (1-2 quarts per week). While driving down the highway the oil pressure light came on and the engine started clicking and knocking. The engine died and all the dash lights came on. The car was coasted to the side of the road and towed into a local mechanic. The engine had seized and presumably dumped all the oil at the time of the engine failure since the engine had no oil when diagnostic was run. Car was taken to Hyundai dealership and is awaiting diagnostic and repair.

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.

I was driving with my 2year old grandson and my car stalled. My neighbors waving trying to alert me that my car was on fire.By the time I realized that the smoke began to come in through the vents. I had to use the key fobe to open the doors to hurry and remove my grandson from the car. The door's wouldn't open by pulling the handles. There were no warning lights or lamps messages or problems prior to the engine failure. The safety of my grandsons and my life were put to risk because of me not getting any notifications about recalls and defects.
