Hyundai Sonata abs comes on

Filed Aug 23, 2026 · Electrical, Visibility · IL

Blower motor malfunction at night. Smelled something burning. Extremely hot and humid outside. Windows fogged up inside which greatly reduced visibility. Checked the multifuse which controls the ABS, oil pump, cooling fan, & Blower. I discovered a burnt connection on one of the terminals for the blower. This is a huge safety and fire risk and needs to be addressed ASAP!!!! Upon my research, I’m finding several Hyundai Sonata vehicles having this same exact issue. Kia vehicles are being recalled for this same exact issue. Why isn’t the Hyundai Sonata??

My 2013 Hyundai Sonata (VIN [XXX]) suffered a driver's airbag clock spring failure, completely disabling the primary restraint safety system. ABS light was on, the horn and all other electronics on the steering wheel were not functioning. All symptoms indicated in the recall This vehicle is explicitly covered under Hyundai Extended Warranty Campaign TXXA/TXXJ for 15 years/unlimited miles. However, Hyundai's validation systems are actively rejecting my VIN and blocking my federal right to a cost-free safety remedy or repair reimbursement. I replaced clock-spring and mechanic suggested i check into the recall. I attached receipt for repairs INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was heading to work when suddenly smoke started pouring from the air conditioning vents, and the ABS and traction control warning lights came on. I hit the brakes to pull over, only to realize I had lost braking power. I managed to steer to the side of the road as carefully as possible and bring the car to a stop—despite having no brakes and a fire burning under the hood. I tried downshifting to slow the vehicle, but the transmission didn't respond, and the cabin began filling with smoke. Once I stopped, there was nothing I could do to extinguish the fire, as the car was completely consumed within seconds. It was a fire in the engine bay; I lost the brakes, and the ABS and traction control lights lit up. I assume it was a critical failure in the braking system, most likely involving the ABS module.

I am submitting this complaint because I believe this issue presents a serious safety concern. My 2014 Hyundai Sonata experienced a failure related to the steering angle sensor, causing the ESC, ABS, and traction control warning lights to illuminate while driving. As a result, these important safety systems lost functionality and were no longer available to assist in maintaining vehicle stability and traction during normal driving conditions. This failure occurred without warning and required replacement of the steering angle sensor, followed by a required calibration. A critical steering-related component should not fail under normal driving conditions, especially when its failure can disable multiple electronic safety systems. Drivers may not immediately realize that these systems are no longer functioning, increasing the potential risk during emergency maneuvers, wet road conditions, or sudden avoidance situations. While researching this issue, I found that many other Hyundai owners have reported similar steering and electronic stability control problems. I respectfully request that the federal safety agency investigate whether steering angle sensor failures, related steering system components, or the associated calibration requirements represent a widespread defect affecting 2011–2014 Hyundai Sonata vehicles. If this issue is determined to be common, I ask that Hyundai be required to address the defect through an appropriate recall or extended warranty program so owners are not responsible for repairs involving a critical vehicle safety system.

I am reporting a pattern of systemic failures on a 2012 Hyundai Sonata Hybrid with approximately 131,000 miles. This is my second the federal safety agency complaint regarding this vehicle and manufacturer. Primary Safety Concern — Engine Wiring Harness: During a recent engine replacement at an authorized Hyundai dealership, technicians identified damage to the engine wiring harness and documented in writing that the owner “might have issues with drive ability.” The dealership declined to repair it under the same goodwill program used to replace the engine and returned the vehicle with this known defect unresolved. The harness directly controls engine operation, hybrid system communication, and overall vehicle control. On a hybrid vehicle, a compromised harness presents a serious and ongoing safety risk. This component is available for inspection upon request. Engine Failure: The hybrid system warning light appeared prior to failure. The vehicle was towed to an authorized dealership where diagnostic code P1326 confirmed engine failure. The manufacturer acknowledged this and replaced the engine under goodwill. Additional System Failures: A pre-scan diagnostic revealed simultaneous fault codes across six systems — engine, transmission, ABS, active hydraulic booster, battery management, and motor control unit — including codes U0293 and U1004 indicating lost communication with the hybrid powertrain control module across multiple systems simultaneously. Independent Safety Advisory: A separate independent repair facility documented in writing that the vehicle presented a severe wheel hub bearing noise and formally advised of an extremely dangerous driving condition. Prior the federal safety agency Complaint: My first complaint to the federal safety agency involved this same vehicle when the manufacturer refused to provide a loaner during an extended recall-related repair hold, requiring formal escalation before they complied. The wiring harness defect remains unrepaired. The vehicle is driven daily out of necessity.

We think there’s an issue with the abs module and wheel speed sensor because we started having a problem where the brakes wouldn’t work or would stutter. The car would shake real bad it would make an awful grinding sound but normally only when trying to stop at higher speeds or long braking. The only thing that made it stop was to unplug the abs but then other parts of the car stopped working like the speedometer and the sensors around the car. So we got the abs replaced but the new one started doing the same thing. We did some research and it sounds like the same issue Hyundai is having with the palisade. The incident that made us get it replaced to begin with was were driving down the road and we got to a traffic light but when we tried to brake they just didn’t work so we drove through the red light luckily the one person who was supposed to be going saw us and didn’t pull out in front of us so we didn’t get hit. We haven’t taken it to the dealership yet but my sister who teaches automotive repair at the community college is the one who diagnosed it so she said we should report it here so maybe it won’t happen to anyone else. Before we had the brake issue we were having problems with basically everything on the dash not working randomly. We’d be driving down the road and the speedometer and the outside sensors and the gas gauge and the traction control all would go out at the same time it’s the same stuff that went out when we had the abs unplugged so it seems that might be related.

ABS module/brakes system goes into limp mode randomly, which causes brake malfunction, throwing codes c1233, c1234 and c1236. There was a recall repair performed by Hyundai about two years ago, however there was two options on the federal safety agency recall 23V651000/campaign 251. One was to replace a safety plug fuse issue, TSB 23-01-054H . That is the recall they performed. The other recall repair which they did not perform is to replace the ABS module. The Hyundai dealer says I must pay a $225 diagnostic fee for them established they need to do this recall repair . Does that sound correct to you?

The contact owns a 2011 Hyundai Sonata. While driving at an undisclosed speed, the vehicle lost power, an alarm sounded for the braking system, and the vehicle went into LIMP Mode and the vehicle failed to exceed 15 MPH. After originally paying out-of-pocket for an ABS module at the dealer and was informed that the engine needed to be repaired and the brakes needed to be replaced. The vehicle was towed to the residence where an independent mechanic repaired the vehicle. There was a recall for the ABS module and the contact returned to the dealer, and the dealer confirmed that the independent mechanic had correctly installed the part. The dealer performed the official recall repair and refused to reimburse the contact for the previous expenses. Three months later, the braking system failed again. The contact stated that the vehicle temporarily returned to normal after a restart, but the failure worsened and required a return trip to the dealer for another repair. In January 2026, the failure recurred for a third time with a loud squealing sound. The dealer was not notified of the third failure. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 80,000.
