29 days after I bought a 2018 Hyundai Tucson. The vehicle started making a ticking noise and stopped accelerating. I called the dealership and they said we didn't get a warranty. I said no that isn't correct, no warranty was offered and after seeing ALL the known engine problems I understand why ken ganley in medina wouldn't offer one. Now not even a month into having this vehicle, I have a brand new 5 year loan and a vehicle that won't move until I put a new engine in it and the dealership won't do anything for me. This is the worst experience I have ever had purchasing a vehicle

It's an engine failure. The car died in the middle of the rode at a traffic light with busy traffic flowing. It was confirmed by a independent service center. No one other an the independent service center has inspected it. There were no warning lamps or messages before failure.

Since I purchased the car in 2018 I took great care of it, keeping the services going on time. But recently in October 2024 even tough I did services the oil service’s sign keep on showing up. I then schedule an appointment with a dealer ship near my area in January and they told me that they were no oil in the car. But I show them the date ans mileage on my stickers I specified that is the reason I am here and to double check for me for filtration because something is wrong, they told me that the car was fine. Days after I had to go in my regular service place for another service and on May I drove the car from Massachusetts to New York and in the middle of the way car start shaking, making noise and when I drove it to a shop they diagnose a failed engine. I left the car in Goshen NY in a Hyundai dealer ship and they told me a valve un the engine was burned and that where the problem came from . They said , they fixed it. A friend pick up the car and 30 mnt driving it police came to rescinde her in the highway, they then told me that’s it’s was a failed engine and days after ask for services record, I provide the last 6 times , they asked me from 0 until today. The shop were I take care of the car don’t keep record from so long. Talking about 2018. They said they won’t fixed it without those record . The car is still under warranty with 71321 miles and I have it for 7 years.

My 2018 Hyundai Tucson 2.0L GDI engine with only 79,000 miles was "knocking" and wouldn't accelerate. We pulled over and towed the vehicle to the local Hyundai Dealer who declared "oil level good but failed bearing clearance test". Diagnosed with a rod and bearing failure. They submitted to Hyundai Motor Warranty the vehicle needed new engine. They declined. I know this is covered under the Hyundai Engine 2 Class action lawsuit with the extended 15 year/150,000 mile warranty as a result of the catastrophic engine failures. I have all oil change service records for every 5,000-6,000 miles while I was the second owner, as well as, have obtained another from the dealer who bought it from a rental/lease company starting at 14,000 miles. Hyundai Corporate is claiming "exceptional maintenance neglect" because of one missing oil change record from the rental company that I may not be able to obtain as the paper trail for the rental car company only states first owner was rental/fleet

After an impact with a large buck (deer) on a main highway while traveling 70 miles per hour, the airbags failed to deploy.

Component: Engine Vehicle: 2018 Hyundai Tucson VIN: [XXX] Approx. Mileage at Failure: 79,413 miles Incident Date: [XXX] Where It Happened: While driving [XXX] At 79,413 miles, my 2018 Hyundai Tucson (VIN: [XXX}) suffered complete engine failure without warning. The vehicle had been properly maintained (records from Express Oil Change & Tire Engineers), and was operating under normal conditions. The dealership diagnosed total engine failure and quoted $7,723.88 for replacement. They are not replacing the engine with the same type, which may indicate a known issue. There are no active recalls, but similar engines in Hyundai vehicles from this era have been subject to recalls and warranty extensions. I believe this may be due to a manufacturing defect. No injuries occurred, but the failure posed a safety risk while in traffic. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2018 Hyundai Tucson. The contact stated while driving 70 MPH and depressing accelerator pedal, the vehicle started to decelerate. The contact pulled over to the right side of the road and turned off the vehicle. The contact waited for two minutes and attempted to restart the vehicle; however, the vehicle failed to respond as needed. The brake warning light was illuminated. The vehicle was towed to an independent mechanic where it was diagnosed with a misfire in cylinders #1 and #2. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 20V543000 (SERVICE BRAKES, HYDRAULIC); however, the VIN was not included. The manufacturer was notified not notified of the failure. The failure mileage was 177,000.

On April 12, 2025, my 2018 Hyundai Tuson which only has 99,000 miles started stalling out at random speeds. The vehicle stalled going up a hill and would not accelerate it would also not go past 55-60 miles per hour on the highway. There were no check engine lights or codes on the dashboard. The vehicle is also burning oil on 2 occasions when having the oil changed. I feel like my life and others is in danger because the vehicle is stalling at random speeds which could cause a major accident due to this issue. I could be hit by another vehicle while trying to accelerate or merge on the highway. I reported the oil consumption last November and I contacted Hyundai customer care who issued a case number in May 2025 for the stalling issue, they instructed me to take it to the Hyundai dealership to be diagnosed. There is a recall out, but they said my vehicle is not included in it. I took the vehicle to the dealership, and they confirmed the vehicle was stalling and would not accelerate and were able to reproduce the issue. They informed me the vehicle needed a new transmission, and the vehicle only has 99,000 miles. Hyundai and the dealership declined to add the vehicle to the recall campaign for stalling vehicles. I had to cover the cost of $3,000 for a new transmission. I picked the vehicle up on June 6,2025 with the new transmission installed and it is still stalling and won't accelerate past 45 miles per hour.

I noticed my vehicle was burning through oil, initially indicated by a P011 code, when I called Hyundai they said its often a symptom related to low oil pressure. After oil changes, the code would clear, but it returned multiple times, and on two occasions, the dipstick showed no oil when checked. Despite staying current on oil changes and maintenance, I was dismissed as excessive oil burning being “common” for this engine. After recent recall updates at the dealership, a technician confirmed excessive carbon buildup and that my catalytic converter was beginning to plug. I inquired about an extended warranty offered due to the knock sensor installation but was told it only covers rod bearing failure. Hyundai Corporate echoed this, stating no coverage until catastrophic engine failure occurs, despite the ongoing damage from oil burning and converter clogging. Since my visit to the Hyundai dealership, the symptoms have rapidly escalated. Now, my vehicle is extremely loud and acceleration is poor. It takes a long time to get up to speed, and I worry about driving it as it may result in an accident.
