Open the full vehicle complaint log (all categories)Was told by dealership that forward camera assist is not functioning, but could not tell me why it failed all of a sudden. No accidents. $1586 to repair because no longer under warranty. Vehicle is only 5 years old.
While driving the vehicle suddenly started alarming indicating to check "Forward Collision Warning" followed by an alert to check "Lane Keeping Assistant." Immediately pulled off the road shut the vehicle off and checked the perimeter. No issues noted. Issue continues, while waiting for service from local dealers.
Both waning lights came on for lane assist and forward collision warning. I took the vehicle to the dealership. They said the camera was not working and I would have to pay $1700.00 to install a new one. It appears there are 2 separate cameras involved. I was asked if I struck anything. I did not and the camera in the grill is I damaged as is the forward collision camera in the rear view mirror. The paperwork I received from the dealer says “software error” I have not had the work done due to the cost. I was also told by the dealer that they are aware of other customers with the same problem.
The contact's father owns a 2020 Hyundai Tucson. The contact's father stated that while driving at various speeds, the Forward Collision Avoidance message was displayed; however, there was no other vehicle nearby. The vehicle was taken to a local dealer, where it was diagnosed that an unknown sensor needed to be replaced; however, the contact's father was made aware that there was a backorder on the part. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 5,000.
It happened on two different occasions but only when driving at high speed using the Cruise Control. Here is what happened. Driving on the Cruise Control I “Set” it to 70 mph. Driving on the two lane highway with both lanes blocked by other vehicles, I pressed the “brake” pedal. The car slowed down and I continued driving at a lower speed. When traffic in front of me cleared, I pressed the “Resume” button on Cruise Control. With no obstacles in front of me, my car was supposed to accelerate to the previously set speed of 70 mph. Instead, it was slowing down. When pressing the gas pedal the car was not accelerating. It felt like the car “lost power.” It felt like the automatic transmission shifted to a Neutral or may be the lowest gear. Pushing the gas pedal did not do anything and on both occasions I managed to steer the car to a road shoulder. It was a scary situation with heavy fast moving traffic on a narrow mountain highway. I stopped the car, then tried to go again. It would go very slow on, what felt like, the lowest gear without acceleration. I then stopped the car again and turned off the engine. Turning the ignition off resets the electronics and I was able to get back on the road. The car continued to drive normally on Cruise Control until the same happened again the next day. As I said, it happened on two different occasions. From there on I avoided pushing the “Resume” button on Cruise Control and I am afraid of using it from now on to avoid potential accidents. I consider this to be a life threatening malfunction and I reported it to Hyundai’s Customer Care. They opened the Case Number and suggested going to the nearest dealer. I took the car to the nearest dealer. They kept it for several days, drove 40 miles and, as I expected, were not able to replicate the problem. In my opinion, this problem needs to be analyzed by the engineers not a dealership's technician. Is speed a factor? Is temperature a factor? What is the factor?
Hyundai Tucson Sport 2020, this happens always, while driving in the highway, long distance the forward collision warning activates (no cars in front of me or any objects) and the SUV make a sudden stop and it sound a loud scary noise, then I have to park, turn it off and then start the SUV again because the rpm starts going up. This is a safety hazard, luckily no one was behind me or I could get hit in the middle of the highway. I took the SUV to the Hyundai dealership where I bought it in San Juan, Kennedy, but they said they didn’t find anything. I took it then to the Hyundai dealership in Caguas, P.R. to have it check and still waiting on a response. It’s been a year and still no one finds what’s the problem. I feel my life is at risk when driving in the highway.
For at least the last 60 days, the blind spot warning camera system will disengage while driving. Took the vehicle to the local dealer, who had the car for 2 days and could not determine the cause. They did discover it will disengage after driving the car for 18 miles. They have called Hyundai for assistance. So far, no information received back from Hyundai on how to correct this issue.
