2020 Hyundai Tucson

burning oil at a rate of 2 qts per 1000 miles driven. Known issue in these models of tucsons. Not covered by the class action lawsuit as this VIN was not identified. It is burning oil at a catastrophic rate. The problem has burned through multiple catalytic converters that were covered under the warranty but did not solve the underlying problem. Has been burning oil since owning the car a year ago.

Component: Engine / Electrical System / Fuel System Incident Date: February 9th, 2026 Vehicle Speed: 45-50 MPH Description: While traveling at highway speeds on a major roadway, the vehicle experienced a catastrophic and sudden engine stall without any prior warning or dashboard indicators. The engine shut off completely while in motion, resulting in an immediate and total loss of power steering and power-assisted braking. I was forced to perform a high-effort emergency maneuver in heavy traffic to reach the shoulder and avoid a collision. This vehicle is used to transport myself, my coworker and my family whose lives was placed in immediate danger by this failure. Since the start of the financing agreement, this vehicle has a documented history of recurring sensor issues and failed repair attempts at the dealership (Route 1 Hyundai). The dealership has previously attempted to address electrical/sensor malfunctions, but the root cause remains unresolved, leading to this life-threatening stall. I believe this is a significant safety defect in the vehicle’s electrical or fuel management system that poses an unreasonable risk of accidents and injury.

2020 HYUNDAI Tucson Engine blown @ 89,307 miles and 1,265 miles after oil change due to missing oil plug. Daughter drives about 5 miles per day for college and groceries. The day before Thanksgiving 2025, her 2020 HYUNDAI Tucson died about 48 miles down the Highway without warning, no prior warning lights or sounds before shutting down. I had the car towed to the local HYUNDAI dealer in the town where her college is, where they told us the engine was totaled due to a lack of oil and a missing oil plug. I discussed with the HYUNDAI service advisor about having an extended warranty; however, they would not work with me or the company I had the extended warranty with, mentioning they would not cover the engine failure due to the oil plug being missing. I asked the service advisor in a separate conversation whether an oil pan drain plug that was not properly torqued during an oil change could remain in place for some time—particularly during short, low-speed driving—and then gradually work loose over additional miles. The service advisor mentioned that in situations like my daughter’s, where only about 1,265 miles were driven after the oil change (mostly short trips), it would be within reason for an improperly installed drain plug to stay in place until a longer highway drive with higher RPMs, at which point it could back out completely and result in a sudden oil loss and engine shutdown. The service advisor also mentioned that this is something they had seen before and is not unheard of on these vehicles.

The car has been burning oil for about two years . Noticed when my oil was changed by my mechanic , he told me oil level was about a quart low . Since that time I have had to add oil every 1000 miles . Approximately 4 quarts between oil changes , which I have done every 5 to 6 thousand miles . I have read that many other people have had same problem. This is a 2020 Tucson, Unlimited Model . Which at the time of purchase was the top model Tucson on the lot . Hopefully this is enough information to help get the consumer some Help in this situation ! Thanks

On December 27, 2025, while driving, the engine suddenly lost power and the vehicle entered limp mode and became undriveable. A warning light appeared and diagnostic code P1326 was later confirmed, indicating engine bearing failure. The vehicle could not be driven safely and required towing to a Hyundai dealership the following day. The engine failure caused a loss of propulsion safety risk. The vehicle remains out of service pending a full engine replacement. The vehicle is available for inspection at a Hyundai dealership.

I have experienced 4 repeated issues within 4 months with my vehicle. Starting in September 2025 and the 4th and current issue today 1/12/26. Driving when all of a sudden all of my brake components lamps come on dash oard, forward collision alert, and check engine, my vehicle struggles to accelerate accurately. Blue Link diagnostic throws various codes such as ECM, Transmission Control System, even "multiple possible issues". Each time my vehicle has been at Hyundai dealership for repair. Each time they repair something different 1st- replace ABS module and hydraulic brake, 2nd - happened out of state at my mother funeral and replaced my ECM, 3rd couldn't figure it out and guessed it was my Forward collision camera and replaced it, 4th - is today and awaiting dealership diagnosis. This issue has left me stranded several times local and long distance, occured in middle of driving including on highway, and overall uncertain of the safety and reliability of the vehicle as each time it has been the same type of issue. I have been in communication with Hyundai Corporate since October and they stated that even tho I only have 24k miles on the vehicle that it is outside the state of IN lemon laws for a buyback. If I hadn't purchased an extended warranty I would be in even more debt or unable to put it in the shop even tho I don't feel like this should be my burden when I have kept this vehicle in great shape, low mileage, frequent oil changes, etc . however the safety of my vehicles goes unresolved. At this point I am uncertain that Hyundai is properly diagnosing my vehicle and not certain how these issues are impacting other components of my vehicle such as brakes, transmission, engine, sensors. I am the only owner of this vehicle bought brand new. I have checked repeatedly for any recalls that I have not addressed and at this time none are pending. I fear that this vehicle will continue to have more safety issues.

The contact owns a 2020 Hyundai Tucson. The contact stated that the engine was consuming an excessive amount of engine oil. The vehicle was taken to the dealer, and the oil level was topped off. The dealer requested that the contact return every 1,000 miles for inspection. The failure persisted, and the vehicle was returned to the dealer every 1,000 miles. The check engine warning light was illuminated. The vehicle was taken back to the dealer for an inspection, and the dealer discovered that the catalytic converter was defective and needed to be replaced. The vehicle was taken to an independent mechanic for a second opinion, and the contact was informed that the engine had failed due to a defect in one of the engine cylinders. The dealer was informed of the findings by the independent mechanic, and an appointment was scheduled to inspect the vehicle. The vehicle was not repaired. The failure mileage was unknown.
