Hyundai Tucson abs comes on

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)

While driving, the digital instrument cluster on my 2025 Tucson Hybrid Limited goes completely black and displays only "NO SIGNAL" in red, along with multiple warning lamps (AFS, ABS, EPB, airbag/brake indicators). The speedometer, fuel gauge, gear position and all driver information disappear while the vehicle is moving. This happened multiple times - recent was on Thu, Oct 29, 2026.

The contact owns a 2016 Hyundai Tucson. The contact stated that while driving at an undisclosed speed, the vehicle experienced issues with the brakes on the driver's side. The vehicle was taken to both an independent mechanic and a dealer, where technicians from both locations diagnosed a brake system issue. Later, while driving at approximately 15 MPH, the contact noticed a yanking sensation before the vehicle began slowing down on its own. The contact drove the vehicle back to her residence, where she noticed a burning smell. Once stopped, she observed smoke and discovered that the brake caliper had caught on fire. The contact extinguished the fire herself using a garden hose, and the vehicle was subsequently towed to the dealer. The contact noted that weeks prior to this incident, the vehicle's brakes suddenly locked up on their own with no warning while driving at an undisclosed speed. The contact stated occasionally there was burning odor with smoke but could not tell where it was coming from. The dealer has confirmed that the ABS breaks need to be replaced. The contact stated the calipers were replaced twice before, now that the brakes had caught fire they recommend the ABS module to be replaced. The vehicle was not repaired. The failure mileage was 120,000.

ABS light on dash is illuminated due to no known cause. Mechanic explained that the ABS system will not work when the light is illuminated which, I believe, contributed to a "fender bender" my vehicle was involved in due to the ABS system failure.

The contact owns a 2019 Hyundai Tucson. The contact stated that while driving approximately 30 MPH and depressing the brake pedal, the vehicle responded as intended; however, several unknown warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed and determined that the ABS had failed and needed to be replaced. The vehicle was repaired at the owner's expense. The contact became aware that notification for the federal safety agency Campaign Number: 20V543000 (Service Brakes, Hydraulic); was previously received; however, the VIN was no longer included in the recall. The contact was unsure if the recall repair was performed. The contact requested a reimbursement from the dealer, but the request was denied. The manufacturer was not notified of the failure.

Multiple warning lights on the dashboard, including SRS , tcs, ABS , all lights stay on even after turning the vehicle off. Systems don't work, such as lane departure, collision avoidance & ABS don't work. Spoke w/ koeppel hyundai, mentioned the issue, but was told that that isn't part of the recall, therefore they will not adress the issue. It's frustrating , don't feel safe driving the vehicle. Will take legal action if any accidents will happen due to an issue that the dealer is refusing the adress.

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)

The 2.0L engine catastrophically failed during normal highway driving, consistent with a thrown connecting rod. The vehicle suddenly lost power on a roadway with tractor-trailer traffic. The driver and a child passenger narrowly avoided being struck by a semi-truck before the vehicle could be brought to a safe stop. No prior warning lamps, no check engine light, no abnormal noises, and no indications of any kind preceded the failure. The failed engine is currently at a Hyundai dealership and is available for inspection. The dealer has confirmed catastrophic engine failure and submitted an engine replacement request to Hyundai Motor America. Hyundai Motor America declined the engine replacement request, citing incomplete status on Service Campaign 966 (Knock Sensor Detection System update for connecting rod bearing wear). The owner purchased the vehicle used and was never notified by Hyundai of Service Campaign 966. The owner also was never notified of the federal safety agency Recall 20V543000 (ABS module fire risk), which remains open and unrepaired on this vehicle, demonstrating a pattern of failed manufacturer notification to the current registered owner. This vehicle is a Class Vehicle in the Hyundai/Kia Theta II engine class action settlement (In re: Hyundai and Kia Engine Litigation), which extended powertrain coverage to a lifetime warranty for connecting rod bearing failure on 2018 Tucson vehicles equipped with the Theta II 2.0L engine. The failure mode experienced is precisely the defect this settlement and Campaign 966 were designed to address. Component that failed: engine, specifically connecting rod bearing/short block assembly. Component is available for inspection. Vehicle has approximately 71,000 miles. The failure created an immediate and severe risk of fatal collision involving a child passenger. Manufacturer has been contacted and has denied warranty coverage. the federal safety agency action is requested regarding both the engine defect denial pattern and the unrepaired ABS fire-ri
