The vehicle has a difficult time turning over when cranking, the RPMs are sticking and the car periodically shuts off at red lights. Several warning lights pop up when it won't crank and then other warnings when the car just completely shuts off at red lights. I drive the interstate in [XXX] daily for work, so with the engine stalling my safety is at risk every time I drive it. Likewise when it won't crank, my safety is at risk. I had two Hyundai recalls updated in my car in 2022, Hyundai Recall 209 which was a connecting rod bearing test and my car passed so they installed the other Hyundai Recall 966 which was software update for the knock sensor detection system to alert the driver of future issues. Those issues are now current. The software is detecting a critical failure which is why the car is shutting off - entering limp mode, or the engine is failing. On April 9th through the 11th, 2026 my vehicle was inspected by a Hyundai dealership, where a technician identified a developing engine concern and advised me to continue driving the vehicle.

Following the knock sensor detection system update, this car has a P1326 code that forces it into limp mode. Occurs during moderate-hard acceleration, e.g. getting on a highway. The car is limited to -??2000 RPM and -?? 45 mph, and rapidly decelerates to that speed if necessary. Acceleration is very limited. This occurs roughly every two weeks, despite having a brand new sensor installed by Hyundai. Hyundai has also allegedly performed cleaning on the sensor and related parts. This has been going on since November, when the recall that installed this update was performed.

I am writing regarding a serious incident involving negligent automotive service performed by Jiffy Lube Store #687. On October 24, 2025, I took my 2017 Hyundai Tucson to this location for a standard oil change. I trusted that the service would be completed properly and safely. However, on November 21, my vehicle-??s oil lamp unexpectedly illuminated. Concerned, I returned to Jiffy Lube on November 22, where employees informed me that they had -??sealed the small leak and topped [my] oil, -?? adding that I was entitled to two top-offs between oil changes and -??should be good for two weeks.-?? Tragically, the very next day, November 23, the oil lamp flashed again. My vehicle then shut off while I was driving, with my children in the back seat. This was a frightening and dangerous situation for all of us. I am now left confused, stressed, and unsure of the full extent of the damage.

The controls (buttons) on the right side of my steering wheel progressed from slow to respond to completely unresponsive, and then the driver airbag light started coming on. At first it was intermittent, then constant. I didn't expect those two issues to be related but did come to learn it was the clock switch. According to my Hyundai dealer, this is a known issue in several other years/models of Hyundais and they have extended those warranties, "but it hasn't reached the Tucson yet". I was told that either 1 - my airbag wouldn't deploy or 2 - it would deploy randomly when I was driving the vehicle. I spent nearly $1000 in diagnostics and repairs.

Rear driver side door suddenly will not open from outside or inside. A rear passenger would be essentially trapped in the car should an incident/accident happen. I googled and it seems this is a well known issue affecting several model years of Hyundai, including my 2017 model. I do not see a recall for this extremely dangerous issue.

I am writing to report a serious issue with our 2017 Hyundai Tucson. As the first and only owners of this vehicle, we have diligently maintained it through authorized dealerships. However, in May 2023, while driving on the highway, the car suddenly lost power and would not accelerate beyond 30 mph. There were no warning lights or indications prior to this incident. My wife managed to pull the car to the side of the road and slowly drove it to the dealership. Despite having only 30,000 miles on the odometer from personal use, we were shocked to learn that the engine had suffered significant damage due to low engine oil. Notably, we had recently serviced the vehicle at the same dealership just a few months earlier. The dealership informed us that the engine needed replacement, but the process took nearly a year. During this time, we were left without our vehicle, causing considerable inconvenience and financial hardship due to renting replacement vechile. We find it concerning that an engine failure occurred despite our regular maintenance and adherence to authorized service centers. We kindly request an investigation into this matter and hope that steps can be taken to prevent similar incidents for other Hyundai Tucson owners. Additionally, we urge Hyundai to address this issue promptly and transparently.
