2022 Hyundai Tucson

While driving, I accelerated to merge onto the highway. The check engine light flashed a few times and the engine started wobbling like it was misfiring. I have also been having a parasitic drain on my auxiliary batter that makes the car not open to my key fob that I know works. The dealership told me it was bad fuel, but they “tested the fuel” with no diagnostic report/proof/records, saying that the fuel was bad and had a high concentration of 5% alcohol. They re-did the test and took pictures which shows the fuel is within tolerance but no diagnostic report and are refusing to complete a warranty checkup on my engine/electrical system. Also, the misfires with acceleration due to merging has happened 3 times. From the start back in July 2025 till now.

Brand/Model: Bridgestone Alenza AS Ultra Size: 235/60R17 DOT Code: 1W281AAU11925, W281AAU1025, W281AAU14124, W281AAU10525 Purchase Date: July 28, 2025 I am reporting a catastrophic and unpredictable treadwear failure on a set of four (4) Bridgestone Alenza AS Ultra tires (80,000-mile warranty / 800 UTQG). Despite professional maintenance, these tires have degraded to a legally bald and unsafe state (2/32") in less than 8,000 total miles. The tires exhibited a sudden "melting" effect. On October 31, 2025 (Odo: 28,330), a third-party inspection verified a safe tread depth of 9/32" with even wear. However, by February 20, 2026, the tires had dropped to 3/32", and by March 20, they reached 2/32". This represents a loss of 7/32" (70% of usable tread) in only ~3,800 miles. This rapid, non-linear degradation creates an emergency safety hazard, as the tires lost wet-weather traction and hydroplaning resistance in less than 30 days between service checks. Maintenance History: The vehicle (2022 Hyundai Tucson) has a documented history of proper care: Professional Alignment: September, 2025 (Insurance-certified). Tread Verification: October 31, 2025 (Confirmed 9/32" and even wear). Rotation Service: February 20, 2026 (Performed at 7,500-mile interval). The failure is global across all four tires, including the non-driven rear axle, indicating a fundamental rubber compound defect. Retailer (Costco)has denied warranty support, citing "rapid wear" as a non-covered issue, despite the tires failing 72,000 miles before their engineered lifespan. This defect leaves the consumer on the road with unsafe, bald tires that failed without warning.

Yesterday used front passenger side seatbelt and it worked fine. Today it did not work at all, seatbelt does not latch.

The touchscreen is not reposnive to touch except in one tiny corner. We’re reported this at thw Hyundai dealership at least three times over the years- they said “they can’t see a problem”, which is odd because the screen literally does not respond to touch. When it’s hot, even with the AC on full blast, sometimes we will be driving and the touchscreen starts making beeps and starts going into the settings menu all on its own without being touched, and starts randomly changing settings. Or, we will connect a phone with google maps, and the screen will randomly change to something else or a different view. This is a dangerous distraction, and Hyundai has refused to acknowledge this problem. The screen is unusable, we are forced to use our phones to use navigation directions just to be safe in our own car. This has been an issue starting in 2023 and to this day has been persistent. We have done both hard and soft resets to ni avail. We have also reported, on going to the dealership, that the screen says to update- they have never provided any update or instructions on how to update, even though every time we go to the hyundai maintenance we are there for at least two hours or more.

The contact owns a 2022 Hyundai Tucson. The contact stated that while stopped, the vehicle hesitated to respond, with the check engine warning light illuminated. The contact stated that while the vehicle was parked, it was shaking unexpectedly with a misfire coming from the engine, and the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the fuel injector had failed and needed to be replaced. The vehicle was repaired. The contact later stated that while driving at an undisclosed speed, the vehicle lost motive power, with the check engine warning light illuminated. The vehicle was taken back to the dealer, where it was diagnosed and determined that the cylinders had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 69,000.

High pressure fuel injectors went out.

Bought the 2022 Hyundai Tucson. It was driving perfect no issues then I hit 52,000 miles and the check engine light illuminated. The vehicle started sputtering and idling hard like it wasn’t getting fuel when the gas was pressed. I was on the interstate and the vehicle wouldn’t go over 35mph. Now the check engine light illuminates off and on when it feels like it.

This vehicle has a considerate amount of oil dilution problems. I have had this vehicle taken in for service several times due to gasoline mixed into the engine oil. Again on March 6 2026 for the 4th time now the vehicle has a check engine light extreme hesitation with an almost stopping jerking motion due to dilution problems. Multiple dealerships claim there is nothing wrong with the car.. there is a distinct gasoline smell in the engine oil. The vehicle at times is almost unsafe to drive due to the hesitation and halting it does on its own. Every time a dealership is contacted my problem is dismissed. There is a burning smell due to the oil gas dilution issue. The car reaches higher temperatures than it should. And now the Hyundai dealership is making me wait almost a month again to have the problem looked at again which then puts me as the driver in an unsafe situation to drive a vehicle with such hesitation and fire risk. If they dismiss this oil and gas mix again and do not repair the car it could seize my engine or maybe possibly even cause fire damage.

I am dealing with this issue where I am getting fuel injector issue and getting cylinder 3 misfire and air fuel imbalance code. It comes and goes. I spent 1500 bucks flushing fuel system and replacing spark plugs and coil. But the issue is still there! i changed the battery and got it to dealership they said they could find the issue. I was on freeway going southbound near exit 34 when the car starts shaking and I lost acceleration

After inspection by a few people it was determined that the front passenger side lower frame cracked which then cracked the body oozing rusty water out of it. I was told that if the car was hit on the passenger side that it would not retain its ability to be stable and would crumple. It has been inspected by the Hyundai dealership, A general manager from another dealership and 3 auto body welders. This first appeared in December of 2025 after I had washed my car and was drying it off.

I have had 2 failures of the EGR valve. The first was covered under warranty. Hyundai is refusing to cover the second repair even though I think it should be covered under the 80,000 mile federal emissions warranty. The vehicle currently has 73,000 miles.
