Vehicle caught fire damaging wiring harness. engine has hesitation, AC system was damaged by fire. recall shows electrical system/engine and brakes in recall. Hyandai refused to replace citing missed oil changes. oil was changed regularly but not always at the dealer. These particular problems are exactly what the recall was for, problem is design and manufacturing the oil change issue has no effect. I want these fixed as soon as soon as possible
My truck was stolen so most likely they messed up my ignition. Before this my lights keep going out every time I replace one a different one goes out. Wheel always going out of air and my truck always jerking when driving or breaking. I am a victim of the "Kia and Hyundai" boys in Baltimore city that's going around stealing people cars.
My vehicle was broken into on Nov. 17, 2022 and thieves attempted to take the vehicle after smashing the back passenger window and gaining access. The vehicle alarmed once they either attempted to either open the drivers side door or start the vehicle. Police were called and completed a report on scene. On Nov. 23, a thief returned and gained access to the vehicle by shattering the glass on the back driver side of the vehicle before getting inside and driving off in the vehicle. I reported the vehicle stolen to police and the vehicle was recovered later that evening. On Nov. 25 I went to the tow yard where the car was taken to retrieve my belongings and observe and record the damage. The entire steering column was stripped down and damaged which is how the thief was able to start it. …
I have had my 2017 1.8L eco Hyundai Tucscon for 3 years now and recently it's been giving me signs of problems that are great concerns for safety, as well-known for this models; it only 62091 miles as of the day of this complaint. On Jan 15. 2023, I noticed that each time I start the car, it takes a little bit longer, then you hear a rattle sound and shaking of the engine block, then it start. Or the engine would suddenly slip, followed by a brief rattle sound while driving. I took it in for service to Manly Hyundai in Santa Rosa on Jan 27, 2023, but the mechanics there told me that they could not find where the problems are coming from, and that I would need to wait for an engine light to come on, as any diagnostic at this point maybe unnecessary and costly. …
On July 22nd, the duel clutch malfunctioned & caused the vehicle gear shift to no longer engage. The car does not move in Drive or Reverse. It can only be pushed in Neutral or towed. This occurred while I was driving home on the highway with no warning lights or prior symptoms indicating a potential issue. The vehicle has not yet been seen by Hyundai but they did say that since my VIN was not registered to the existing recall, there is not much they can do & any repairs would be out of pocket. It has been seen by our family mechanic, PepBoys & has currently been sitting at AAMCO with no solution as of today since August 2nd. Geico said since this is a mechanical issue & not an accident, they cannot assist. Carmax Customer Relations (where I purchased the Vehicle on March 12th, 2023) has been informed but so far offered no solutions. …
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. …
