Ford Mustang abs comes on

Filed Jan 23, 2026 · Brakes, Driver assistance · VA

While driving at normal road speed, the vehicle suddenly displayed multiple warnings at the same time indicating that AdvanceTrac (electronic stability control), traction control, and ABS were disabled, and the vehicle entered a reduced functionality state. These warnings appeared simultaneously without any hard braking, loss of traction, or driver input at the time. The warnings and system faults then cleared in a cascading manner over a short distance, with each system returning one after another while continuing to drive, without shutting off the engine. After approximately a few thousand feet, all warning messages disappeared and the systems appeared to return to normal operation on their own. This has occurred more than once since ownership. The first occurrence happened at approximately 50 mph. The second occurrence happened at approximately 20 mph and occurred only seconds before an emergency braking event in the rain to avoid a collision. At the time the warnings appeared, the vehicle had temporarily lost ABS, stability control, traction control, and related braking assistance systems, creating a serious safety risk during an actual emergency maneuver. After the events, an OBD-II scan was performed and no stored fault codes or diagnostic trouble codes were present. However, for the next several engine on/off cycles, the steering and traction control behavior felt abnormal, as if the systems were only partially engaged, even though no warning lights or messages were displayed. No permanent warning lights remained illuminated afterward. The problem is intermittent and difficult to reproduce. No collision occurred, no repairs have yet been performed, and the cause is currently unknown

The shift knob in this car has an issue where the silver ABS plastic piece with the gear numbers and the shift pattern detaches from the rest of the shift knob. This issue has been confirmed and repaired by a Ford dealer twice already in the 9 months I have owned the car. The first time this issue occurred, the silver piece was loose. Before it completely detached, I was able to get it repaired at a Ford dealer. The issue was confirmed by the dealer in the receipt they gave me: "Verified customer concern, shifter knob loose, the aluminum to the leather, replaced shifter knob. No other concerns at this time." The second time this issue occurred, the silver piece suddenly detached when shifting gears during normal city driving. When this happened, the silver piece flew off the shift knob and fell into a gap next to the passenger seat. I was able to get it repaired at a Ford dealer again. They again confirmed the issue on the service receipt: "Verified customer concern, Replaced gear shifter knob". This is a safety issue since it is hard to tell what gear I am shifting into if the plastic piece with the shift patterns breaks off. Once the piece breaks off, it is not easy to grip the shift knob normally, requiring the driver contort their arm in a different direction to grip the shift knob, making it harder and slower to shift. As someone who is experienced with the car, I can get around these issues. However, if someone who just started driving this car experiences this issue, they may not be able to shift gears or shift into reverse, since they may not be familiar with the shift pattern. During the second occurrence of the issue, it caused a lot of confusion and momentarily reduced my attention to the road and the surroundings as I was shocked by the shift knob suddenly breaking and the piece flying off. I attached pictures of the second occurrence of the issue and receipts from the two service visits to a Ford dealer.

ABS light came on, sometimes when braking/slowing down at freeway speeds, the brakes won't catch and it feels like I'm going to ram into the cars ahead, I've replaced the rotors, the calipers, the brakes, the wheel bearings, ABS light won't go away, I've looked into it on the bullitt community forums, and this is a common problem that most just decide to live with, cause no solution has been found.

This is a 2024 Mustang convertible that I purchased from Autonation in Panama City and the back window was not properly installed and is now shaking and allowing water into the car. There is a major problem with the car disabling ABS as well and ive taken it to the dealership for both of these issues twice. The brakes did not function correctly when I was dropping off at school and I tapped the parents car in front of me. I went to autonation with my concern and even called FORD to file a complaint and neither of the companies took it seriously. Had I known this car was gonna be a problem and even more difficult to fix (Autonation doesnt work on convertible tops and has given me the run around about finding someone to fix the top) I would have kept my older convertible. I ALSO PURCHASED AN EXTENDED WARRANTY WHEN I BOUGHT THIS CAR TO ENSURE EVERYTHING WAS PROTECTED.

The steering gear including contour module went out. I was backing out and couldn’t turn my wheel my sisters boyfriend had to drive it home on a curvy road with no power steering. I have a local mechanic looking at it but they said the part is on back order which means this must happen a lot. They finally got the part and now are saying it won’t program so are needing to order another part. When I turned the car on to leave my destination it said service powersteering system and abs, but before that there were no warnings. I unplugged the battery for 30 minutes to rest the car and everything worked fine for another 1, then driving down the road it went out again.

The front brakes grab suddenly during low speed braking under about 6 mph causing the car to jerk to a stop. The front brakes will lock up when coming to a stop at higher speeds at about 25 mph if the car is downshifting gears. The low speed issue happens for about 80 percent of the stops and the higher speed braking issue is hit or miss. There are no warning lights indicated on the dash. I took the car into the dealership with about 3000 miles on it. The dealership said they could not duplicate, it was just how abs works and that I needed to drive more miles and it would go away. I put the pick up date for my car as the incident date but as this is a current and ongoing issue it is every date.

Traveling on highway using cruise control at posted speed limit. Approached slowdown due to accident and applied brakes. Accelerated to limit (manually) after passing accident. I was in middle lane. Vehicle abruptly began to decelerate. Continuous pressure on gas pedal did not increase speed, so I put on hazards and moved to slow lane. No failures on dashboard and quick scan through gages did not identify an issue. Re-applied pressure to gas pedal wanting to get to next exit. Car sped up, but when approaching 50 mph, it decreased again. Found that pumping gas would allow me to maintain highway speed. Pulled into truck stop at exit and turned car off. Message on console "Hill start assist not available". Let vehicle rest 15 minutes, added gas. Quick web search seemed to point to problem with ABS sensor. Seemed to drive ok in parking lot and road leading to highway ramp. Decided to try to get closer to home. Problem occurs immediately after climbing to 50 mph. Cruise control won't work. By carefully monitoring speed and pumping gas into overdrive when needed, I was able to get home. Could not get appointment with dealership until late afternoon next day. Hill start assist message comes on again when stopping. After arriving home and parking in garage I went inside for about 30 minutes. Needed to unload items from car and went back to garage noticing that the strip of lights above trunk are still on. Got back in car, started it (got hill assist message), turned lights on/off and turned off car. Now my rear brake lights are also on. I had seen a post about this, so unhooked battery to prevent drain. Next morning, reattached battery and had same problem. After more internet investigation, Awesome humans who have also had this dangerous issue and provided a $5 fix instead of a $500+ dealership fix. https://www.mustang6g.com/forums/threads/brake-light-switch-near-pedal-failure.122100/pag SUDDEN UNEXPECTED THROTTLE CAUSING SLOWDOWN ON BUSY INTERSTATE IS LIFE THREATENING.

Due to a faulty design the vacuum pump that drives the break booster is connected to the cam with a threaded camshaft extension. This part sheared off causion the vacuumed pump to loose vacuum and the break booster to unexpectedly stop functioning. The vehicle was in motion on the interstate. The failure was noticed after attempting to break. The residual vacuum prevented the break light from illuminating temporarily. The breaks became difficult to press, ABS sporadically engaged and the breaking situation was uncontrolled placing life and property at risk.
