UNKNOWN OR OTHER, WHEELS
The situation I’m about to explain has happened twice—once in December 2025 and again on January 22, 2026. In December, the roads were very icy, but there was no snow on the ground. As I made a right turn into a Walmart parking lot, I heard a loud metal-breaking sound while turning. I immediately got out and looked underneath my 2018 Hyundai Tucson SEL but didn’t see anything unusual. After finishing my shopping, I started the SUV to pull out of the parking space. The car was trying to move, but the rear tires were not moving at all. A man waiting for my parking spot noticed this and told me one of the tires wasn’t turning. As I drove home, I heard extremely loud metal noises coming from the back of the vehicle—sounds like metal twisting, breaking, and falling to the ground. At no point did any warning lights come on. I took the car to a highly rated mechanic, Premier Car Care, where they did a thorough inspection and found nothing wrong. After being reassured that the vehicle was safe, I continued driving it. Then on January 22, 2026, the same issue happened again. I was driving to my internship, and the roads were slushy. Suddenly, the Tucson became unstable, slid unexpectedly, and I heard the same metal twisting and breaking noises. This time, the ABS light came on briefly and then went off. The vehicle felt unsafe and unstable, even though I was driving very slowly—around 15 miles per hour. I was terrified and nearly hit someone. I had the car towed through Triple A back to the mechanic, but once again, they were unable to find the cause after inspecting it, and it is sitting in my driveway. I am reaching out because I am on disability, I have three children with autism, and I am also currently in school. I rely on this vehicle, and I truly need help investigating what is happening so this issue can be properly identified and fixed before someone gets seriously hurt.

The car began making a knocking sound on my 5.8 mile drive. On my drive home from work, the knocking was louder, and the car barely accelerated on the highway and over-revved trying to hit at least 50 mph to keep up with the flow of traffic. I took the car to the Hyundai Service Center immediately using city streets rather than the highway. I had a family member follow me to make sure I made it to the service center as well as give me a ride home after I dropped off the vehicle. As I was driving there, the car had a hard time accelerating from a stop and barely maintaining speed of the flow of traffic and the “Check Engine” light came on and flashed as I got closer to the dealer service center. The dealer service center confirmed that the engine needs to be replaced due to the connecting rod bearing failure, a common issue with the 2.0L I4 F DOHC 16 V engine in my 2018 Hyundai Tucson. The Hyundai Service Manager has repeatedly confirmed that the engine issues presented in my car are consistent with a recall for the same model engine found in my car.

ENGINE, POWER TRAIN, VEHICLE SPEED CONTROL
The engine and engine management system of my 2018 Hyundai Tucson experienced repeated failures resulting in loss of propulsion and unsafe drivability. In November 2025, while traveling approximately 75 mph on a freeway, the vehicle suddenly entered limp mode without any prior warning, causing an abrupt loss of power in active highway traffic. No warning lamps or messages appeared before the failure. After the loss of propulsion occurred, the check engine light, battery light, and oil light illuminated sequentially. Diagnostic trouble codes P1326 and P0326 were recorded. Initial inspection indicated severe oil consumption despite a recent oil change less than 2,000 miles earlier. A Hyundai dealership replaced knock sensors under warranty. Shortly after release (30 miles), the vehicle again exhibited severe drivability issues, including a flashing check engine light, and required immediate towing. A second Hyundai dealership replaced the short engine block under warranty. Approximately 180 miles after the engine replacement, the vehicle again developed unsafe drivability symptoms, including delayed throttle response, failure to accelerate unless the accelerator was fully depressed multiple times, jerking or lugging when slowing or stopped, and a faint whining noise. The check engine light illuminated again. These failures represent repeated loss of propulsion and unsafe operation following manufacturer-approved repairs, including full engine replacement. The vehicle has been out of service for approximately 57 days and remains in the custody of a Hyundai dealership awaiting diagnostics. The vehicle is available for inspection upon request. The sudden and unpredictable loss of power at highway speed created a significant risk of collision and serious injury to the driver and surrounding motorists.

My 2018 Hyundai Tucson has been experiencing oil consumption issues for over a year. It began at around 80k miles, when it should have been covered by warranty but they made me pay out of pocket for an oil consumption test only to ultimately recommend a top end cleaning, which I also paid for and it did not solve the problem. This is a known issue with Hyundai, and they have settled many lawsuits but have consistently denied any repair or solution for me. I am burning about 5 quarts of oil every week, and this is a problem they refuse to help solve.

The engine on this vehicle burns oil quickly which is a known defect. I took the vehicle to the dealership and both times I was told everything was working fine. On 12/5/2025 the vehicle just lost power while driving. After getting the vehicle towed to a mechanic they said I needed a new engine.

ELECTRICAL SYSTEM, ENGINE
My 2018 Hyundai Tucson experienced complete engine failure at around 118,000 miles. The motor suddenly blew without warning. This vehicle uses an engine type known for widespread engine defects, including bearing wear and internal failure. I bought the vehicle used in 2023, maintained it regularly, and there were no warning lights or overheating before the failure. I had to put oil in my vehicle every week. I had to use 5qts of oil. It smelled like fumes coming through the vents. It then stalled on the highway while we had our son in the vehicle and shaked profusely. Mind you we had our son in the vehicle. How unsafe is that. I then did my research and found out Hyundai engines of this generation have a history of stalling, seizing, and internal damage. I am filing this complaint because this appears to be part of a known safety defect that can cause sudden loss of power while driving. We took it to shop and confirmed the motor blew. It was faulty. Also, sometimes the electrical components would turn off in vehicle such as radio and would go black. Also the turn signal would be on and then turn off. It would also shake while driving. This needs to be taken care of ASAP as it almost caused danger to my family and also caused financial strain on my family too as I now had to roll over my vehicle loan into a new safe vehicle. I would like to be contacted in regards to this. Thank you.

Shortly after purchase, I had an oil change and vehicle inspection performed. I was informed that my engine may have an internal defect causing it to burn oil excessively. I later took the vehicle to a AAA-approved Hyundai service center, where they confirmed that the engine is burning oil due to a known manufacturer issue and that it is not the result of owner misuse or neglect. I have been quoted approximately $11,000 for a replacement engine, which is an extreme and unexpected cost for a recently purchased vehicle in otherwise good condition.

I purchased this car [XXX] as a CPO vehicle from a Ford dealership. By [XXX] the oil pressure light would flicker and it was clear the car was burning a lot of oil between changes. On 8/22 an oil change was completed at dealer. On [XXX] the oil pressure light flickered and it was three quarts down. An oil consumption test was started at 112,000. On Sat [XXX] while driving to dealer for oil check, the car began shuddering violently and the check engine light came on, and went into limp mode. I was on a dangerous mountain pass at the time and it could have been a major issue. The day before a tractor trailer had almost run me off the road, if my car had stalled then I might not be here. Hyundais have a known issue with oil burning and engine damage. Right now I am stuck in a 14K loan with a car that is unsafe to drive. I am not sure what the dealer plans to do, or what the diagnosis is, but its clear these engines are not safe.

The contact's sister owns a 2018 Hyundai Tucson. The contact stated that while his sister was driving at an undisclosed speed, the vehicle briefly jerked and jolted, prompting her to pull over to the shoulder of the roadway to turn off the vehicle. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed failures with all four fuel injectors and the injector assembly. The vehicle was repaired, but the failure reoccurred. The vehicle was taken back to the independent mechanic, who then diagnosed a failure with the catalytic converter. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 78,563.

2018 Hyundai Tucson has excessive oil consumption. Burns multiple quarts of oil per 1000 miles. Hyundai refuses to remedy the oil consumption. Oil consumption has also led to having to replace the catalytic converter due to oil burn off.

AIR BAGS, STRUCTURE:BODY
On October 13th 2025, we were involved in a serious collision while driving our 2018 Hyundai Tucson. The vehicle was struck from behind and spun into a semi-truck, totalling the vehicle. Despite the forward and lateral collision to the semi-truck, no airbags deployed at all during the accident. This resulted in the Tucson driver striking his head on the steering wheel. Our 5-month old son was also on-board the vehicle in his car seat. While everyone walked away from the accident, both adults passengers had whiplash/minor neck injuries that could have been mitigated by airbags deploying. We have serious safety concerns about Hyundai's airbags because of this incident.
