Hyundai Tucson electrical problems

I just bought the car, it was brand new off the lot. The check engine light came on followed by every emergency warning on my dash. After this my power steering failed, I was able to move over to the right lane a bit, but that’s it. I tried turning the car off at this point and turning it back on, but it would not turn back on. I could not even put on my emergency 4 way blinkers. The car would not even detect the key at this point. Thankfully we were on a small, low traffic road and not the freeway or a major accident would have been inevitable.

While driving, all of the warning lights on the dash came on and the car shut off. After pulling over, the car started again. The car was bought on 10/18/22 and the first incident was 11/7/22. It was taken back to the dealership, the lights were turned off and a few days later it happened again. This happened a total of 4 times. The last time only 3 lights came on. As of this complaint, the car has been in the shop since 12/22/22. There were no warnings before the lights came on. The Hyundai mechanic said that those lights mean there are major issues and it could be a safety hazard. The car was not bought at a Huyndai dealership.

The contact owns a 2017 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the vehicle was shuddering with several unknown warning lights illuminated. Additionally, the speedometer, turn signals, and temperature gauge failed to operate while driving. The vehicle was towed to the dealer, where it was diagnosed with electrical system failure. The dealer replaced the vacuum pump. The manufacturer was made aware of the failure but informed the contact that there was no recall associated with the VIN. The contact related the failure to Technical Service Bulletin: 19-01-010H (Tucson Vacuum Pump Sealant Application/Cap Replacement) however, the vehicle was not covered by the TSB. The failure mileage was 78,388. The consumer stated all warning lights illuminated and outside thermostat stopped working for about 20 minutes into the drive. Also, problems with shifting gears and gear shifter was stuck in park.

The car has been erratic in its performance since purchase. The car has a continuous issue with the suspension, electronic system, and brakes. I have reached out to Hyundai manufacturer on numerous occasion regarding the car and no one is addressing my concerns. The car drives so erratic and unpredictable that I am fearful that someone will be injured or worst. Attached is a photo of the entire system going offline, which occurs all the time, and because the whole care is computerized this poses a safety risk for me and others on the road. When the car goes offline, I no longer have control of the vehicle and all mechanical systems are down. Please help me to get this issue resolved before someone gets hurt. This is the second submission in regard to this car. 5nmjfcae4nh015882

The contact owns a 2022 Hyundai Tucson.

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. There are highly circulated videos on social media platforms showing criminals or would be criminals how to do this. It is now also known that they are targeting specifically Kias and Hyundais due to Hyundai manufacturing cars between 2016-2020 without immobilizers. My make and model being one of them and therefore making me a target. Not only that but the cars are being taken and used for joy rides, as mine was, or used in crimes. My car sustained additional damage as it was crashed into another vehicle during the thieves joyride before they ultimately jumped out of the car and abandoned it in an intersection. I was targeted, my livelihood put in jeopardy and if the car is fixable I will still be in harm's way once the repairs are completed. Hyundai needs to be held accountable as there is no way I would have purchased this vehicle knowing that the car was missing a major safety and anti-theft component. Further, why were they allowed to manufacture and sell these cars without such an important component??

The headlight and taillight/break lights burn out constantly. Turns out taillights are melting in socket. My car is not uniquely affected. Many are having same problems. Suddenly losing lights while driving on freezing dark roads. Incredibly unsafe. Not isolated to my car. Very dangerous. The company should replace these sockets and reimburse for the bulbs which have been replaced approximately 6 times in 12 m.
