2020 Hyundai Tucson: ABS light or ABS activating

Filed May 18, 2026 · Brakes, Driver assistance · FL

In August/September 2025 my mother's Tucson would randomly shut down on her (completely stall while driving) and she would not be able to turn it back on. If she waited a little while, then she would be able to turn the car back on but it was unknown when the issue would happen again. We took it to the dealer several times after each shutdown and the dealer stated it was not throwing a code and they could not diagnose the problem. The last time we took it to the dealer, the vehicle shut down while they were test driving it and they discovered it was a rear wheel sensor which is part of the ABS system. When the car would stall, lights on the dashboard would start flashing and the car would shudder to a stall. Since repairing that rear wheel sensor, the car has not exhibited the issue until 3 days ago when it again shut down randomly while she was in traffic. This, of course was terribly frightening for her as cars were honking at her and whipping around her vehicle. She was not able to get the car started. A police officer came and parked behind her car, calmed her down, and got her to try the car one more time and it did start up and she was able to proceed to the closest parking lot. After that we followed her home and have an appt. set to go back to the dealership. We are expecting the same run around at the dealer who charges excessive fees to diagnose and then repair the car. My Mom is [XXX] so this is a dangerous vehicle for her to be driving (really for anyone) as I am reading on line others reporting this same condition. I am expecting that they will find that a different rear wheel sensor has failed for which they will want another $800.00 to repair or maybe more now. Obviously we must get rid of this vehicle. It has less than 25,000 miles on it because she only drives to the grocery store and back. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have experienced 4 repeated issues within 4 months with my vehicle. Starting in September 2025 and the 4th and current issue today 1/12/26. Driving when all of a sudden all of my brake components lamps come on dash oard, forward collision alert, and check engine, my vehicle struggles to accelerate accurately. Blue Link diagnostic throws various codes such as ECM, Transmission Control System, even "multiple possible issues". Each time my vehicle has been at Hyundai dealership for repair. Each time they repair something different 1st- replace ABS module and hydraulic brake, 2nd - happened out of state at my mother funeral and replaced my ECM, 3rd couldn't figure it out and guessed it was my Forward collision camera and replaced it, 4th - is today and awaiting dealership diagnosis. This issue has left me stranded several times local and long distance, occured in middle of driving including on highway, and overall uncertain of the safety and reliability of the vehicle as each time it has been the same type of issue. I have been in communication with Hyundai Corporate since October and they stated that even tho I only have 24k miles on the vehicle that it is outside the state of IN lemon laws for a buyback. If I hadn't purchased an extended warranty I would be in even more debt or unable to put it in the shop even tho I don't feel like this should be my burden when I have kept this vehicle in great shape, low mileage, frequent oil changes, etc . however the safety of my vehicles goes unresolved. At this point I am uncertain that Hyundai is properly diagnosing my vehicle and not certain how these issues are impacting other components of my vehicle such as brakes, transmission, engine, sensors. I am the only owner of this vehicle bought brand new. I have checked repeatedly for any recalls that I have not addressed and at this time none are pending. I fear that this vehicle will continue to have more safety issues.

In May of 2023, my house burnt down. We were in it at the time when the smoke detector went off. When I opened the door from to kitchen to the garage, I saw flames shooting up at the front of my car. The fire was so intense at that moment, I knew all we could do was flee the house. I grabbed my wife and we ran out the front door. You do not have a recall listed for my vehicle, but Hyundai lists two. The first one listed can potentially cause a fire. Both recall maintenance was performed on my car. I sincerely believe that the car was the cause of the fire. Since it had been sitting in my garage for approximately four hours, the engine wasn't hot. I had it regularly serviced at the local Hyundai dealership. There were multiple fire investigators, including one from Hyundai. Here is the recall information.

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.

The car engine completely shuts down without warning. This has happened over a dozen times since last summer. The only thing we can think of was the ABS module recall work, but the dealership says everything is fine with the car and they cannot replicate. This happens when the car is at a stop, or sometimes driving slowly or turning. The engine gets quiet, the lights flicker, and then gas no longer works to accelerate. To fix this, we have to shift the car back to P, then turn the car off, then turn it on again, and then put it back into D. Sometimes this happens in the middle of live traffic which is unsafe. We have an active case with Hyundai America open about this issue since the dealers cannot identify and fix the issue. This is a high safety issue for my family and other drivers. The car is available for inspection. The frequency of this occurs about once a week (it used to happen 1-2 times per month but recently has been increasing.)

I received a letter stating my 2020 hyundai tucson is affected by a recall concerning the ABS modules that could cause an engine compartment fire. I called to schedule a recall repair and the dealership stated hyundai has not yet released the parts to make the repair. I was told they did not know when the parts would come in. With a serious recall like this, these repairs should be made asap.

I was notified in september of 2020 that there was a recall to install a fuse kit into the ABS module electrical circuit and update the ABS software on my vehicle. It is now march 2021 and hyundai still does not have the parts to correct this problem. Since this is a fire hazard, I see this as an issue that they need to promptly correct. 6 months is too long to be waiting when they know there is a problem.

Received a recall notice from hyundai with an obvious sense of urgency instructing me to schedule a repair asap!!! That was november 2020. This recall affects the ABS system of my new vehicle. Today is january 8, 2021 and still no fix and according to dealership, they have no idea when this will happen!!! No parts from hyundai available. Very concerning and frightening to drive this car due to fire hazard. In addition, the recall letter instructs that I should not park the car inside or near a structure. I live in hudson valley, new york and we are in the middle of winter here. I now sit with an empty two-car garage and have had to dig my car out of snow, scrape it from ice, and put air in the tires because of cold temperatures. This is unacceptable customer service by hyundai, putting drivers in this potentially dangerous situation. \my dealership has me at #61 on their recall list with no idea of when the repairs will be done. This could take a few months, in their opinion. I

Service recall 195 for ABS system and potential fire hazard. Hyundai says not to drive because of safety risk and that parts are not available nationwide. Apparently this is only for existing cars if you buy new they will fix the problem and have parts available immediately. How is that possible?

My 2020 hyundai tucson was purchased new this year from west herr hyundai I'm williamsville ny. I was notified of a vehicle safety recall related to ABS issues in september 2020. I have contacted the dealer every week sense then, and they claim they are unable to compete the recall due to a lack of parts. I believe the dealer is negligent in addressing this issue and I would appreciate help getting this safety issue remedied.
