2020 Hyundai Tucson

The oil is burning up so fast. Every oil change that is within the mileage limits they tell me my car is bone dry. If the oil in my car runs out my car engine can blow up or it can stop working. The only way it has been reproduced is that every oil change for 2 years now they have told me it’s bone dry. It has not been inspected by manufacturer. They told me it would cost about $400 for them to even just check it out. There are no warning lights at all.

Jan '22 - Reported check engine light had begun to turn off and back on when gas tank was low. Feb '22 At 19k miles catalytic convertor reported failed for code (P0420), 3 way catalyst, upper and lower gaskets, and manifold all needed to be replaced - took 4 days Aug'23 called to request service for check engine light because it was coming off and on over periods of time. Scheduled for Sep'23 Sep '23 service reports new cat quoted for code P0420, I was not verbally informed by service advisor. 16 Nov '23 driving home and car starts to shake and is slow to accelerate, check engine light started to flash, car enters limp mode, could not drive safely on highway and waited hours for a tow. Codes P0420(cat convertor), P1326 (Knock sensor) 25 Nov '23 picked up car, had catalytic convertor, manifold gasket, knock sensor replaced. Drove 27 miles and car check engine light begins flashing again (P1326) on freeway while merging. Car hesitates, starts to slow, had to merge over to shoulder from far left lane as car had no acceleration. I felt unsafe to exit vehicle being 9 months pregnant. Waited 2 hours for tow back to service dept the same day I picked up vehicle. 8 Feb '24- picked up car from service department. They performed engine combustion chamber cleaning and reported excessive cylinder wall scoring. Service advisor feels confident this fixed the problem. I feel unsafe driving a car that has left me stranded multiple times on busy highways and freeways, especially with children. The manufacturer keeps replacing parts and cannot seem to diagnose issue, they keep repairing problems caused by a major issue that has not been diagnosed.

I was involved in a motor vehicle accident on January 14, 2024. My vehicle was struck head on, left driver side. The airbag did not deploy. I sprain my shoulder, fractured my chest rib, and have a knee contusion. My insurance company deemed my vehicle a total loss. I contacted Hyundai and they advised that because I did not currently have vehicle in my possession, they could not inspect it. I gave Hyundai the contact information to view the vehicle and they refused, stating they do not get involved with insurance company. My vehicle has not been inspected and my insurance claims representative is awaiting a call from Hyundai, to view vehicle at storage location. There were no warning lamps or other symptoms stating that the vehicle had an issue prior to the accident. My vehicle had a successful all points system check in May 2023, at a Hyundai dealership.

While driving down the interstate to go back to my college, I noticed a cloud of white smoke coming out of my exhaust. Seconds later, I no longer could accelerate and white smoke was also coming out of the engine. There were no lights on my dash at this point or at any point before this day. I quickly tried to get off of the road when I noticed my car was no longer going. I managed to get to the side of the road where finally my engine and oil light came on. I waited 2.5 hours for a tow truck on the side of the interstate, where I was barely off of the road. It was taken to the dealership where I bought it (since the car only has 32k miles on it) for a "hole in the engine" which is what I was originally told by the service department. Two days later, I received a phone call that there actually was no hole in my motor, and that the drain oil plug disappeared from my engine while driving, causing all of the oil to spill out of my engine that day on the interstate. Despite getting an oil change only 1500 miles ago from this exact dealer, they stated that the plug would have fallen out immediately after their service if it was placed back incorrectly. Hyundai stated this is now an "owner's problem" and that I was to call my insurance company to get an estimate from them because the dealership would not cover it since it was no longer a warranty issue. I called my insurance company who then got pictures from the dealer of the engine and a video. They then called me stating this type of damage is not covered under my policy, and that they would not pay for it. So here I am, stuck with Hyundai refusing to pay for a damaged engine even though the oil drain plug fell out, which inherently caused the damage, and despite having a 10 year/100k mile warranty on the motor. I found out there is an open investigation through the NHTSA about this exact issue and was hoping to receive clarity on what I can do.

NHTSA should have a non-official recall warning for Hyundai vehicles that have this software based Safety Defect, which is some models don't have a Passive Engine Immobilizer, and the vehicles can be easily stolen by starting the engine with a USB cord. Thankfully Hyundai(recall) offered a free Anti Theft Software Update, and a steering wheel lock. I checked my VIN number with the Hyundai Dealership in Oregon, and they said my car already received the Anti Theft Software Update. The only reason I knew my 2020 Tucson had this issue, is because State Farm cancelled my insurance a month after I started paying for it. State Farm and Progressive currently deny new policies for vehicles without a Passive Engine Immobilizer. Also State Farm still denied my insurance after I got the software update. Affected Hyundai models from 2011 to 2021 that have standard “turn-key-to-start” ignition systems/without a Passive Engine Immobilizer, are the Accent, Elantra, Santa Fe, Sonata, Tucson, Genesis Coupe, Palisade, Kona, Venue.

Traveling on the highway and the engine decelerated, oil pressure light came on briefly and then went off. The engine light went on. Was not able to accelerate past 50 mph. The car was hesitating and shaking. Had to change lanes and drive a distance to get to safe place. Engine starting knocking and got worse the longer it was driven. Was a safety risk as unable to go any faster than 50 miles per hour and hard to steer with car shaking. Car has 79,384 miles on it. Dealership states engine failure and that engine needs to be replaced. Car had burned up almost all the oil that had been replaced two months prior. Hyundai currently has a recall for this exact problem with their 2017 Tucson’s
