  I took my car in to Allen Samuals Hyundai dealership to have the 9C2 recall update completed on May 15th 2026. Ever since then my vehicle has had a rough hesitation or sputtering when driving. On May 18th Hyundai released a statement stating there was an issue with the update completed on the 9C2 campaign. However no resolution at the moment and to allow the car to warm up prior to driving it. I have only had my car for a little over 2 years and maintained everything a responsible car owner should. It only has 90k miles on it and had zero issues at all prior to the 9C2 campaign. I have spoke woth dealer and corporate numerous times nobody can give me a solution nor does it seem that anyone wants to. Since then the campaign has been closed and its almost as if it never existed. I do have an active case open with Hyundai 43228380 however they act as if they dont know anything about it. They are empathetic to the situation but can't really help or give a solution. All I want it my car that had zero issues prior to this update to run properly again. I dont even drive it much anymore for fear that it will mess my engine up.

  This vehicle burns oil at an alarming rate. I am getting oil changes every 3K miles, and when I take it in, the dipstick is dry. I receive no oil lights to tell me it is low. I just had to get spark plugs and the mechanic at the garage told me this was due to the oil consumption issue in these vehicles. I am at 71,000 miles.

For the rod bearing failure, Hyundai is denying the claim, saying there's a gap in maintenance history on a car. I didn't own yet when I bought the vehicle. It passed a 190 point inspection. There's no way there was anything wrong with this vehicle.I am under fifty thousand miles , and if I was on the highway , it could've been deadly i could not accelerate. No other lights were on in the vehicle, except for the flashing engine light.I have already reported to the better business bureau and they have sent it to arbitration. I have contacted the escalation department for Hyundai.They opened up to separate cases.The agent that was assigned to me didn't even get the code from [XXX], they just denied the claim without it.I have the emails to prove that I had to give it to her. I have.\n All my maintenance history, but as you can see from the text message from XXX Hyundai, they are requesting maintenance for a car that wasn't in my possession yet. They're asking for dates from a year before I had the car, I bought it through EchoPark. I have everyone on my side including fFdelity , as I tried to go through Fidelity and they said they couldn't approve the warranty because of the class action lawsuit against Hyundai for that exact manufacturer malfunction.

  My 2021 Hyundai Tucson has experienced repeated engine-related failures associated with a knock sensor (P1326) fault that causes the vehicle to enter limp mode and lose power while driving. This issue has occurred multiple times at approximately 15,000, 17,000, 41,000, and 90,000 miles and has resulted in four separate incidents requiring towing. During these events, the vehicle suddenly loses power and cannot maintain normal driving speed, creating a hazardous condition while in traffic. The vehicle has undergone multiple repair attempts, including an ECM update and three knock sensor replacements. Despite these repairs, the issue continues to recur and no root cause has been identified. Hyundai has not provided a permanent fix and has advised continued operation of the vehicle unless the issue occurs again. This ongoing condition presents a safety concern due to the risk of sudden loss of power while driving.

  In October 2025, while the vehicle was still under Hyundai’s 5-year warranty, an authorized Hyundai dealership diagnosed a significant electrical failure affecting the ABS/ESC system on my 2021 Hyundai Tucson. The vehicle was experiencing multiple dashboard warning lights, intermittent key fob malfunction, alarm system failure, and progressive electrical instability affecting safe operation. Dealer diagnostic trouble codes included C120001, C167581, and C164202, with technician notes stating “ABS sensor wiring harness fault found.” The dealership recommended replacement of the wiring harness, estimated at approximately $12,000, but no warranty repair was performed. Since the initial diagnosis, the condition has continued to worsen with additional warning lights and ongoing ABS/electrical system instability. The issue remains unresolved and continues to affect vehicle safety.

  While driving on the freeway, my 2021 Hyundai Tucson SE (72,021 miles) suddenly and without warning lost power and entered limp mode. I was able to safely maneuver to the shoulder and exit the freeway. The check engine light came on and is currently flashing. I took the vehicle to AutoZone where code P1326 was retrieved. I then took it to Pep Boys for a full diagnostic where P1326 was the only code present. The Pep Boys report states the vehicle requires immediate attention. The vehicle remains in limp mode and the check engine light is flashing. The vehicle is not being driven as it cannot safely reach freeway speeds. I contacted Hyundai Customer Care and was assigned Case # XXX. I also contacted a Hyundai dealership who attempted to charge a $225 diagnostic fee despite P1326 being a known Hyundai defect covered under recall/service campaign.

  The vehicle experienced a catalytic converter efficiency failure that was confirmed by an authorized dealership in January 2025. The dealer indicated the catalytic converter required replacement; however, the replacement was not performed, and the vehicle was returned to service with an unresolved emissions defect. Less than one year later, the vehicle developed recurring emissions system failure, loss of power, drivability issues, and repeated warning indicators. The vehicle is currently out of service while additional components, including oxygen sensors and spark plugs, are reported to be affected. The manufacturer is declining to replace the catalytic converter and is attributing the condition to oil consumption despite the prior unresolved emissions failure. The issue has been confirmed by dealership diagnostics and has resulted in prolonged loss of use of the vehicle. This appears to be a continuing engine and exhaust/emissions system defect that was not properly remedied when first identified and may affect safe operation of the vehicle.
