Sep 16, 2025Lane DepartureDriver assistance

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.

I went to Thompson Automotive to finance a vehicle and within a month and half my engine blew. There were no engine lights, no lost of oil, no warning, no signs of any error, before this series of malfunctions took affect. I was on my way to the dealership and my car being slowing down to a complete stop as I was getting off the highway ramp. I was traveling at the speed of 25mph, when the car started to make loud noises that I never heard before that day, and completely shut down in front of a huge tractor trailer in traffic. The dealership has had my car since 6/7/24. Now the car has about 85,000 miles on it. I have to pay another $3,000 for my portion to get a new engine. Which is outrageous considering I just agreed to pay $19,990. I am highly disappointed that I lost my job and everything behind this horrific situation that actually feels like a set from the beginning. Now that I’m reading all the comments and unfortunate but very similar situation everyone is suffering from with the particular car. I can’t fathom why it’s still on the market to be purchase for consumers with these major and potentially deadly problems.

Warning lights for Lane keeping, Blind Spot, ABS, Autohold, Foward collision systems came on and will not reset. Reports of this all over hyundai forums and owner fan pages (Facebook, etc). It can fool the driver into believing the car is about to be in an accident prompting panic response in drivers.

Nov 11, 2022Lane DepartureDriver assistance

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.

Jan 21, 2022Lane Departure

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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2020 Hyundai Tucson Plug-in Hybrid verdict →
