Page 2 of 2: complaints 11 to 17 of 17, newest first, as owners wrote them.
Auto would not go into reverse or drive gears at startup in regular parking space. Received a Bluetooth message that Drive Train would not function. Towed to dealership where problem confirmed. Electric engine ordered along with high voltage wires. Upon installation of these parts it was discovered that the Assay Harness was severely crimped during construction of vehicle at the factory and had crimped (cut) wires. Parts ordered and repaired. Hyundai refused to install new electric motor, only replaced Harness and wires. Please note this appears to be a defective auto as built at the factory.
The contact owns a 2023 Hyundai Elantra. The contact had received notification of the federal safety agency Campaign Number: 23V589000 (Electrical System, Vehicle Speed Control) and the recall repair was completed by a dealer. The contact stated while driving at approximately 60 MPH with the cruise control activated, she momentarily disengaged the cruise control to slow for traffic. The contact stated that when the cruise control was re-engaged, the vehicle independently accelerated to almost 100 MPH. The contact was able to slow the vehicle by tapping the brake pedal. The contact stated the failure became a recurring failure. The contact stated no warning light was illuminated. The local dealer who completed the recall repair was contacted and informed the contact that there was no available appointment until December 16, 2023, for the vehicle to be serviced. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 18,000.
Animal chewed the wiring harness causing an airbag malfunction warning and transmission failure. My safety was put at risk because the airbag wouldn't work and the transmission failed while I was driving. The vehicle is being repaired right now with a new harness. Talking with the insurance adjuster. I was informed this was a common issue with this vehicle due to the materials the manufacturer uses. The harness is not properly designed with the proper materials for the environment it is used in.
I turned on Cruise Control at 60 mph and it immediately set itself to 20 mph, braking fast to slow down quickly. This caused the car behind me to slam on his brakes so he would not rear end me. I tried increasing cruise control speed to no avail. I had to turn it off. Once I did not have any cars behind me, I tried once again so I could take a video and of course, it worked as it should. Not five minutes later, my radio turned the volume down to zero, all by itself. 20 minutes later, when I slowed to turn into a parking lot, my car lagged and acted as if it didn't have gas enough to go up a small incline. Pressing on the gas pedal didn't do very much but I made it up the incline and was able to park. I will be calling Hyundai Dealership tomorrow where I purchased the vehicle last year. I do not have any type of pictures or recordings as it just happened and it was a pretty scary event considering I was almost rear ended.
when on a test drive before the purchase of my vehicle, I and my family smelt a burning smell in the cabin. On return from the test drive, we informed our sales person who told us this was characteristic of a hybrid vehicle, and the smell will go away. It has been almost two months and 1,400 miles; the smell is still there. I don't know how and why it comes, but it definitely is smelt from time to time. I cannot duplicate it at will. I did take it to the dealership's service department, they kept it overnight and could not find any issues. When the technician took me for a test drive, it was there when I started the vehicle, but he said he did not smell burning smell, instead he said it was leather smell. I have had several people in my vehicle smell the burning smell, the problem is I cannot duplicate it on demand.
I was rear ended and the air bags didn't deploy. The police and body shop said they should have. The car is unmodified and dealer serviced
