2018 Hyundai Tucson Electrical Problems

I am filing a complaint under the NC Unfair and Deceptive Trade Practices Act (N.C. § 75-1.1) regarding Hyundai’s handling of my 2018 Hyundai Tucson (purchased new May 2018). Since 2019, the vehicle has had repeated headlight failures (at least 12 bulb replacements), persistent “bulb out” warnings, and eventually melted wiring requiring headlamp assembly replacement in 2025.

Parked subject car in garage at approximately 11:15 am after turning off ventilation fan and cutting engine off, which displayed "off" at dash button. At approximately 7 pm (same day) went into garage to retrieve item and heard this loud noise similar to an electric clothes dryer running - wasn't dryer. As I got close to car, heard this same sound.

Bought car [XXX] blew up 2 weeks later knock censor was not put on by first dealership so engine blew on interstate car was possible on fire due to as much smoke was coming from vehicle could of been rear ended engine failure due to that no warning of engine failure tucson knows all these problem and is currently in a class action lawsuit and have known the problem for years dealership had to of known this was going on with this engine but sold the car to unsuspecting consumer I think there was a lot of stuff going on this car was owned by stew hansons then sold to dewy ford to sale which my understanding is they own both dealerships.

My 2018 Hyundai Tucson experienced complete engine failure at around 118,000 miles. The motor suddenly blew without warning. This vehicle uses an engine type known for widespread engine defects, including bearing wear and internal failure.

The car experienced a red, blinking check engine light. We had the car towed to the local Hyundai dealership. Please see attached document for the work that was done.

The headlight and taillight/break lights burn out constantly. Turns out taillights are melting in socket. My car is not uniquely affected.

Left turn signal sporadically works during a left turn. Can be safety issue when turn signal stops mid turn even the slightest turn it can stop working and then when finished turning it turns on again. Reported issue to dealership and is being replaced through extended warranty.

Electric media screen (navigation, radio and etc) died. Screen went black and would not turn on. Car wouldn’t start on first attempt this morning.

While driving after a snow storm 1/29/2022 I had the heat up in the SUV I started smelling something burning. I then lowered the heat and the smell became less. I recently purchased this vehicle as a pre own on December 3rd 2021.

I was made aware of the recall on certain hyundai tucson's 4 months after the recall was originally published in september 2020. I was also not made aware from hyundai, but from carfax via email. When I researched the next steps and made an appointment to have the issue remedied.
