I believe that this car is a lemon. Ever since we bought it we have problems with the engine not performing right. I have got the engine system cleaned multiple times one at the dealership and one at Valvoline Oil Change facility. The engine still didn't run smooth. I would always get the oil changed on time and the vehicle has never been in a accident. Now just yesterday the vehicle while driving on the highway just stalled and wouldn't accelerate past 60mph. Now the check engine light is blinking and all of the lights on the dash are on. Also lately sometimes the forward collision lights will come on and other warning lights and sometimes they wont. Another light that intermittently comes on are the auto hold and epb light and this has been happening since we bought the vehicle. I have taken into Hyundai and they basically were like yea sometimes that happens. I have not gotten the new check engine light checked but I am sure that it is something serious because the car won't accelerate past 60mph. I have read on other discussions that there are many problems with Hyundai engines and believe that I am victim to very poor quality manufacturing in this engine. I also have a 2013 Toyota Camry with 180,000 miles and haven't had one problem with it. This car is a lemon and would like to have some help with this please. I have also made a complaint with Hyundai under their drive train warranty.

On March 13, 2023 while I was driving at about 70 mph on PA route 66, the engine suddenly stalled and fortunately, I was able to move to the emergence lane. I turned off the power and restarted the engine, and it worked. This is the third time that I have experienced the same issue, with other two on I-376. I also couldn't start the engine after refilling gas, so I had to wait for about 15 minutes. I took the car to a dealership but the diagnosis did not show any problem. There was not error code at all. On the internet, several possibilities were mentioned, but I do not have any idea about the root cause.

I have a Hyundai Tuscon 2019, which was pre-certified by Hyundai. This particular car was part of a lawsuit because of a knock sensor issue. The lawsuit information is here: [XXX] The knock sensor failing is not really what causes the safety issue. The engine symptoms when the sensor fails is the issue. The engine goes into "safety mode" which limits the car to a significant slower speed. The problem is that Hyundai has now tried to fix this issue twice on my vehicle, and the knock sensor continues to fail. To be clear, they've replaced the sensor twice. Based on the lawsuit, the court mandated them to fix the knock sensor. They have done that free of charge, but the sensor continues to fail. To me this sounds like a manufacture issue. It is incredibly dangerous when you're on a highway and the sensor fails. It happened to me, and it was almost catastrophic. The car slowed down and there is nothing you can do about it. I noticed there was something wrong very quickly and put my hazards on. If I didn't, I may not be writing you here. You could easily get into a significant accident, and from that could lead to injury or loss of life. I am asking for a review of this. I have my service records as well as recorded conversations with Hyundai corporate regarding this issue. Service records are attached. I live very close to NHTSA HQ and willing to come in if necessary. To me, this is concerning enough for that..

While driving, the engine completely lost power and was unable to go more than a couple MPH. We had it towed to the dealer and they told us it was a common issue on Hyundai engines and the fix was to replace the entire engine. It is available for inspection. Safety was compromised because we were in traffic when the power failed. Yes, we had the dealer confirm it. The only prior warning was that oil consumption was very high, which the dealer also confirmed is common.

The 2019 Hyundai Tucson was being driven home when all of a sudden acceleration was reduced to 25-30 mph. The Engine light went on while this happened. Got the car home, thankfully was off the highway and had it towed to the Dealership. Dealership informed me that it was an engine problem- a cylinder was blown and new engine would be needed on a car that had just reached the 40,000 mile mark. 40 other cars were brought into the dealership the same week and all needed new engines. If this car stopped working on the highway the consequences would have been dire! It is almost 2 weeks without a car- Dealership had no loaners left and we still don't have an answer from Hyundai if they plan to cover the engine still under warranty. We were told Hyundai had been denying allot of engines under warranty. And we were told it takes a long time to get an engine even if approved by Hyundai. If I must rent a car for a month or more, it will be very expensive. If 40 owners showed up at the same dealership in one community in the same week what is happening nationally and why hasn't Hyundai issued a recall? Do we have to wait until people's cars stop operating at full speed on a busy highway causing multi care pile ups before Hyundai speeds up response to repair but more importantly notifies owners of their vehicles this is a problem- a BIG problem!

On March [XXX], at [XXX]., on my way to a meeting, my Hyundai Tucson 2019 suddenly lost acceleration at 35mph. Immediately, the engine light came on and flashed very constantly. The acceleration pedal was not able to give more speed. There was a lot of traffic, and it was a very scary moment. I was very close to the Hyundai dealership at 750 N York St, Elmhurst, IL 60126. I spoke with one of their representatives, and I was informed that they would evaluate the problem, but it would be up to two days before they could give a full diagnostic; this step will be $185.00, but they will call me before they do anything with the car. The dealership paid for my Uber ride back to work, as they said that no loaner cars were available. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On [XXX] as I was driving down the highway, the check engine light came on the dashboard and the car lost acceleration. I could not go any faster than approximately 30 miles per hour. Very dangerous situation when you’re traveling in a lane of traffic that’s is doing 65/70 mph. I was able to get the car to Premier Hyundai, a dealer in Seaside, CA. At that time there was a recall for the Knock sensor. They replaced the knock sensor at that time and did some other services including an oil change and sent me on my way. They told me at the time that the code that had come up was P1326. Entering this incident now, because I realized I had missed reporting this specific incident. This VIN# has had the issues 5 times since the [XXX] incident and I feel very strongly that this is a HUGE SAFETY ISSUE. when this happens when you are driving down the freeway at 65-70 MPH and it suddenly goes into LIMP MODE. You are at the mercy of the cars that are approaching you from behind doing 70 when you're only able to do 30 mph. This is an ACCIDENT WAITING TO HAPPEN. PLEASE Do SOMETHING. I see where you closed an investigation into these issues. - PLEASE REOPEN the investigation and hold the manufacturer accountable. These settlements they come up with are not worth the paper they're written on. The consumer is getting fed up and we need someone to help us.

DP22003 · Loss Of Motive Power
Opened Sep 12, 2022 · Closed Dec 12, 2023
Status: closed (inferred from source dates) · Engine
The National Highway Traffic Safety Administration (NHTSA) received a letter dated July 13, 2022, petitioning the Agency to initiate a safety defect investigation into loss of motive power allegations attributed to oil drain pan assembly failures on certain Hyundai Motor America, Inc. and Kia America, Inc. vehicles spanning Model Years (MY) 2005-2021. The Petitioners cited examples of complaints indicating that the subject vehicles were experiencing rapid loss of engine oil due to oil drain plug back outs, resulting in loss of motive power and/or catastrophic engine damage. Additional complaints were provided which alleged that the oil drain pans lack sufficient structural integrity and are susceptible to cracking. The petition itself can be reviewed at NHTSA.gov under ODI number 11481745. On September 12, 2022, the Office of Defects Investigation (ODI) opened Defect Petition (DP22-003) to evaluate the Petitioners’ request. The Petitioners have provided additional complaints within four supplemental letters dated January 31, 2023, March 21, 2023, May 23, 2023, and August 4, 2023. ODI’s evaluation included the review and analysis of the complaints and supporting information submitted by the Petitioners, as well as additional complaints submitted directly to NHTSA which referenced either the oil drain plug or a crack in the oil pan. After reviewing the available data, ODI has not identified evidence that would support opening a defect investigation into the oil drain pan assemblies of the subject vehicles. Based on a review of the available information, a loss of motive power resulting from an oil drain plug back out has not occurred between the initial sale of a vehicle and the completion of its first oil change. If during an oil change service, a technician fails to remove the existing drain plug gasket before installing a new gasket, it is likely that a proper seal between the drain plug and the oil pan will not be made. An improper seal between the drain plug and oil pan could lead to the backing out on the drain plug, resulting in the sudden loss of oil while driving. Additionally, the provided examples of oil pan cracks were localized to the immediate vicinity of the oil drain plug and/or appeared to be the result of direct-contact with a tool during servicing. There is no information to support that a vehicle-based defect exists relating to the oil pan assembly, and instead the documented incidents are related to the failure to follow the proper maintenance procedures during oil change service. In October 2023, Hyundai published a Technical Service Bulletin (TSB) that provided detailed instructions for oil change service on its gasoline powered vehicles, specifically highlighting the need to remove and replace the existing drain plug gasket prior to reinstalling the drain plug. After a thorough review of the material submitted by the petitioner, the information already in NHTSA's possession, and the potential risks to motor vehicle safety implicated by the petitioners' allegations, NHTSA does not believe that a formal investigation is warranted. Therefore, the petition is denied. A Federal Register Notice (FRN) further detailing NHTSA’s reasons for denial of the petition will be published. The reference numbers for the complaints to NHTSA cited by the petitioner can be found in the petition submission documents in the public file for DP22-003. To review those complaints and the additional complaints ODI added to its evaluation which are cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
