2019 Hyundai Tucson electrical problems

Filed Nov 9, 2026 · Brakes, Electrical · GA

My husband was driving the car to work and all of a sudden a bunch of dash warning lights came on. It was lit up like a Christmas tree. Then the car went into limp mode. The vehicle has been at the dealership 4 weeks. And they refuse to do a 20 min test on the ABS module. It is a part of the HECU Settlement. You can find the settlement at [XXX] My husband is an electronic engineer. He knows why all the lights are on simultaneously. The ABS needs to be replaced. It's causing all the communication to go down that's on that can bus system. That's why all the parts dont make sense to each other. It all boils down to the ABS improperly working causing communication issues. The recall fix did fix the fires. It won't catch fire now but the ABS is still malfunctioning. There's a lawsuit. All vehicles involved in the recall are required a free ABS inspection and a replacement if they are malfunctioning but the dealership refuses to diagnose the ABS. That is the loophole Hyundai has found to not uphold the law. They are not standing by the settlement. They are skirting around from checking the ABS module so they won't find the malfunction. They want us to replace parts that are brand new that my husband just replaced. They want to charge us $700 for some other part and refuse to check the ABS system per the lawsuit. My husband needs that vehicle to work. So he's been out of work for 4 weeks. It's ridiculous! I can't hire a lawyer at this time and it's ridiculous that I may have to. This corporation should uphold their part of a lawsuit! There was already a settlement. My vehicle is included without even submitting a claim. It's ABS warranty is also extended per the lawsuit. I've read it backwards and forwards. I'm so at a loss! I need help. They also refuse to help us with a loaner and that will force us to drive an unsafe car in limp mode off the property when they are responsible for fixing this faulty part per the settlement INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The 2019 Tucson has 60,413 miles. My daughter drives it very low mileage - a couple of miles a day back and forth to school. Friday she was driving and the car lost engine power and it stopped driving. No warning lights. There was a cloud of smoke and it smelled like burning plastic. She was on a busy road but pulled over and quickly exited the vehicle. I had it towed and the mechanic says the engine oil was empty and the engine has seized. We do regularly scheduled oil changes. No lights or warnings and the car just stopped in traffic.

On March 21st, while driving my Hyundai vehicle, I noticed the vehicle began making a ticking sound. After stopping the vehicle, it slowly began catching on fire. The fire ultimately spread and resulted in the vehicle becoming a total loss. This created a serious safety concern and placed me at risk. I later learned there was a recall associated with the vehicle. However, I never received any recall notices because Hyundai reportedly had the wrong address on file. Had I been properly notified of the recall and potential safety risks, I would have done everything in my power to ensure the vehicle was inspected, repaired, and safe to drive. Because I was unaware of the recall issue, the vehicle continued to be operated without my knowledge of the potential danger. The incident caused significant financial and transportation hardship, including loss of reliable transportation and additional financial strain. Hyundai later reached a determination regarding the matter, but I remain concerned about the serious safety risk and the fact that I did not receive proper recall notification before the incident occurred. I am submitting this complaint because I believe the recall notification process and handling of this matter should be reviewed further due to the serious safety risk involved.

The contact owns a 2019 Hyundai Tucson. The contact stated that upon entering the vehicle, there was water overflowing from the front passenger's side floormat. The vehicle was taken to the dealer, but the water entry point could not be determined. Additionally, the contact stated that several unknown warning lights were illuminated. The vehicle was taken to the dealer, where a brake sensor was replaced; however, the failure recurred. The vehicle was taken back to the dealer, where another brake sensor was replaced; however, the failure persisted. The vehicle was taken to the dealer, who diagnosed that the wiring harness had sustained water damage and corrosion due to a clogged sunroof drain. The dealer determined that the wiring harness needed to be replaced. The vehicle was not repaired due to the cost. The contact stated that the repair should be covered by the manufacturer because the failure was a factory defect. The manufacturer was not contacted. The failure mileage was approximately 30,000.

On three occasions while the vehicle was idling, the dashboard screens and interior lights went completely black, and the steering wheel jerked abruptly in my hands. This sudden electrical failure creates a serious safety concern, particularly if it were to occur while driving at higher speeds. The dealer has not been able to reproduce the problem. There were no warning lamps, messages or other symptoms prior to the failure. There were no warning lamps after the problem occurred. The vehicle has been inspected multiple times by a Hyundai dealership. On one occasion, the dealership retained the vehicle for approximately two months but reported no definitive findings despite error codes being present. On a later visit following another failure, no error codes were recorded. The dealership replaced the head/stereo unit and confirmed no active recalls, yet the issue continues. This problem first occurred while the vehicle was covered under an extended warranty, but due to its intermittent nature, it was not resolved before the warranty mileage threshold was exceeded. I have since found numerous similar complaints online from owners of the same model year describing electrical blackouts and steering-related concerns. A Hyundai service manager advised me to dispose of the vehicle, which further reinforces my concern that the defect may be known but unresolved. I believe this issue represents a potential safety defect and warrants documentation and review. Thank you for your attention to this matter.

While driving to work this morning, at approximately 04:25, on a mountain road both my low beams failed out of nowhere. I pullover in to a turn out as my high beams still worked. I go look and my passenger low beam comes back on. I make the decision to get back on the road and drive slower to try and get down the mountain. A moment later the passenger low beam turns off as do my high beams. I do not get any warning lamps for my high beams, just my low beams. I had to drive in pitch black with my hazards on trying to find a turn out or a safe place to pull over. I was not far too from home and drove back with my hazards on. I take my low beam bulb out of the housing and see that the coil blew. I purchase two new halogen bulbs when I went to go and replace them,I found that both low beam sockets had burned. It has not been reported to the dealer as my headlights are out of warrenty by a few years nor was it reported to the police or insurance because I thought maybe all the lights died at once. I have yet to replace my high beams and i'm the only owner of it.

Our Tucson was stolen in Charlotte, NC on [XXX]. The pax rear window was broken and the thieves broke open the steering column to start the car. It appears they used the well-known "Tik-Tok" method. I have record that our Tucson had the "software update" installed, at a local dealership, a year ago. This update (which should've been a recall) was supposed to address this issue. Despite this update, the car was stolen in less than 2 minutes (I have Ring camera pictures with timestamps). I have doubts now that the dealership actually did the update. Part of the update includes a specific window sticker that is to be applied to the driver's door window. That decal is missing. There is no evidence that it was ever there (I have pictures). The car was recovered but cannot be driven. It must be towed due to the damage. Another concern is the engine and drive train. Criminals were out joy riding in our stolen car on an almost full tank of gas. Because the car cannot be driven, I don't know if there is any damage to any part(s) of the drive train. We are now waiting for our insurance company to arrange to have the car repaired. I am very concerned now about the long term viability and reliability of this car.
