2023 Tesla Model Y: ABS light or ABS activating

Filed Aug 16, 2026 · Acceleration, Electrical · CA · crash

COMPONENT/SYSTEM THAT FAILED: The service brakes failed to stop the vehicle. While reverse-parking at low (parking) speed, I applied the brake pedal and the vehicle did not stop as expected, resulting in contact with an object and vehicle damage. The vehicle is available for inspection upon request; it has been preserved and driven only minimally since the event. HOW SAFETY WAS PUT AT RISK: The brakes failed with no warning. Had a person been behind the vehicle, the failure to stop could have caused injury. This is the only vehicle for a family with three children who are regularly transported in it, and I no longer feel safe driving them. REPRODUCED/CONFIRMED BY A DEALER OR SERVICE CENTER: Not yet. INSPECTED BY MANUFACTURER/POLICE/INSURANCE/OTHERS: The insurer opened and then denied the claim and stated that no vehicle telemetry/data was available to preserve. No independent forensic inspection has occurred yet. Police did not attend. WARNING LAMPS/MESSAGES/SYMPTOMS PRIOR TO FAILURE: NONE. There was no warning light, no alert message, and no audible signal before or during the event. The parking sensors did not beep as they normally do. No ABS or brake warning light appeared at any time before or after. ADDITIONAL RELEVANT DETAIL: Approximately one week earlier, the front lower control arms were replaced. It is UNKNOWN whether the ABS wheel-speed sensor or related wiring was affected; the vehicle displayed no related warning at any time. No injuries occurred.

This incident happened on [XXX], I just got the Tesla data and police report. Here are the events as I remembered: - I was driving my 2023 Tesla Y with FSD supervised (v13.2.8) along [XXX] entered from [XXX] and driving close to north of [XXX] without any issue - Noticed a car in front of me braking hard (about 6secs from the recording dashcam footage) - Realized FSD was not braking hard enough (or at least it did not feel like it) - Slammed on the brake for what felt like an eternity (about 2 secs from the dashcam footage) - Rear end collision on the front car at ~25 mph, airbag deployed. I remembered feeling the brake pedal vibrating but did not stop the car at all. By analyzing the raw data provided by Tesla, it is found brake, accelerator, AEB, ABS and TSC were completely messed up after FSD failed, please refer to the attached analysis report. Note: The dashcam video file and the original Tesla data are available for reviewing if any need as I cannot upload along with this report.

We have had numerous incidents of sudden and unexpected braking. Earlier this month while rounding a curve with adaptive cruise control enabled, the car aggressively braked when it saw an oncoming semi safely in the other lane. It was good there were no cars behind us or no doubt they would’ve rear-ended us. Last night - like so many other times the past year or so - I was pulling into a parking spot with a bush in front and, only a few feet in, the car slammed the brakes on even engaging ABS. Usually the warning system just makes a sound or gently applies this brakes but this was jarring. Everyone in the car lurched forward. The date below is from the incident related to the semi. That could have been very bad. My Subaru Outback uses sonar and I’ve never had these sorts of problems.

Emergency braking and alerting engaged. There were no vehicles or objects in front of my vehicle at the time. The braking was hard enough to engage the ABS and bring the car from 40mph to 5-10 mph, risking a rear end collision if someone was behind me. I have owned the car just over 1 year, this is the first time this has happened. No warnings or other errors appeared before the incident and no errors are present after the incident. Neither the dealer or anyone else has inspected the vehicle. Conditions: Dry, Night (9:50pm) no cruise control or lane keeping functions enabled, no cars or objects were seen in front of the vehicle.

I bought the Model Y in Feb 2023, after 2 months of driving, 3 weeks back on 5/14/2023, all of sudden the car lit up Yellow Brake indicator on dashboard while I was driving downhill. I didn't understand what this indicator meant but when I needed to brake - I could not brake at all, so I let regenerative braking slow the car down which it did. I was horrified as I was on the road at that time, so I tried to find parking to park the car and then read online what this indicator meant, but felt very unsafe to drive the car home. Since then Brakes doesnt work and ABS seems to push back my foot hard and Adaptive cruise controld doesnt work at all. I have service appointment on 6/6 which is the first appointment I could find close to my home.

While driving down the road in traffic, several errors started appearing on the Tesla screen, and the vehicle lost power brakes and steering, rendering it impossible to drive safely. The complete set of car systems that were disabled all at once was: stability control disabled traction control disabled automatic vehicle hold disabled lane departure avoidance unavailable ABS disabled steering assist reduced (no power steering) regenerative braking features temporarily limited automatic emergency braking disabled The car is only weeks old. We had the car towed to a Tesla repair center, and they said due to a wiring issue, the wheel weight on the right rear wheel was rubbing against the wire connecting the wheel speed sensor, which led to this cascading series of errors. I'm concerned this is a systemic issue with newer Model Ys. There's a QA or manufacturing defect, and Tesla, along with the federal safety agency, needs to investigate this dangerous safety issue.
