Hyundai Tucson electrical problems

I am writing to report a serious issue with our 2017 Hyundai Tucson. As the first and only owners of this vehicle, we have diligently maintained it through authorized dealerships. However, in May 2023, while driving on the highway, the car suddenly lost power and would not accelerate beyond 30 mph. There were no warning lights or indications prior to this incident. My wife managed to pull the car to the side of the road and slowly drove it to the dealership. Despite having only 30,000 miles on the odometer from personal use, we were shocked to learn that the engine had suffered significant damage due to low engine oil. Notably, we had recently serviced the vehicle at the same dealership just a few months earlier. The dealership informed us that the engine needed replacement, but the process took nearly a year. During this time, we were left without our vehicle, causing considerable inconvenience and financial hardship due to renting replacement vechile . We find it concerning that an engine failure occurred despite our regular maintenance and adherence to authorized service centers. We kindly request an investigation into this matter and hope that steps can be taken to prevent similar incidents for other Hyundai Tucson owners. Additionally, we urge Hyundai to address this issue promptly and transparently.

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.

I was driving home from work and heard knocking sound come from engine. No sensors came on to alert me of any problem. I pulled over and checked oil. There was no oil and it was not due for oil change for another 1,000 miles. Oil is always changed between 3-5K miles. Took it to Gettel Hyundai dealership where it was purchased. They are unable to explain what or why this happened. Took claim out with Hyundai as there is only 60K miles. Hyundai and dealership offered no help because warranty had ended. Just told me it needed a new engine for $8K. Hyundai corporate denied claim also citing lack of service. That is not a valid reason and makes no sense. We provided every paper receipt showing diligent oil changes and required mile maintenance. They never bothered to do an engine oil burning test. After researching this online there is a well-known problem with these engines burning oil. There was no oil leaking. Why did NO sensor alert me there was no oil? This seems like a major safety concern. Hyundai is refusing to take responsibility for this problem and needs to address this properly. This car engine should be recalled.

I am writing to express my serious concern regarding a safety issue with my Hyundai vehicle, and the apparent lack of resolution from Hyundai despite repeated attempts to seek assistance. Last year, I received a notification from Hyundai about a critical safety issue concerning the EMERGENCY FIRE ANTI-LOCK BRAKE SYSTEM ("ABS") MODULES, which could potentially leak brake fluid internally and lead to an electrical short over time. This electrical short poses a significant risk of engine compartment fires, both while the vehicle is parked and during operation. Naturally, upon receiving this alarming notice, I expected Hyundai to promptly address and rectify this potentially life-threatening issue. Unfortunately, my concerns have only heightened as my local mechanic recently discovered a leakage in my vehicle, which aligns with the exact problem outlined in the aforementioned notification. This discovery has left me deeply troubled and anxious about the safety of my vehicle and the potential risks it poses to my well-being and that of others on the road. Despite my numerous attempts to seek assistance and resolution from Hyundai, I have encountered nothing but frustration and disappointment. Every time I reach out to Hyundai's customer service, I am met with vague responses and reassurances that they are unable to provide a solution to the problem. This lack of urgency and accountability on Hyundai's part is unacceptable, especially considering the gravity of the safety issue at hand.

The contact owns a 2016 Hyundai Tucson. The contact stated that after the vehicle came to a complete stop, the accelerator pedal was depressed, and the vehicle lurched forward but hesitated to accelerate immediately. An unknown warning light illuminated, and the check engine warning light was later illuminated. The vehicle was taken to an independent mechanic, who retrieved DTC Code: P073F (Unable to Engage Gear 1), but no repair was recommended. The vehicle was not repaired. The manufacturer was not made aware of the failure. The contact related the failure to NHTSA Campaign Number: 16V628000 (Power Train, Electrical System) however, the VIN was not included in the recall. The failure mileage was approximately 93,000.

When both driving and idling, the car will either stall or feel like it is about to stall, when all of a sudden the vehicle “pauses” for a second and then all of the dashboard lights come on. This has now happened at least 4 times in the past month. It will reset after turning the car off, but on more than one occasion after turning the car off, the engine doesn’t restart right away. Thankfully, the car has restarted and it resets the dashboard lights. My safety is a concern if my car stalls while driving at any speed! I have yet to take it to the dealer, as there’s a VERY long wait for an appointment - another recurring issue. No one has inspected this for me, and it is very concerning. There is plenty of evidence that this is happening to others in both online forums and Hyundai owners sites online.
