2018 Tesla Model 3: ABS light or ABS activating

Filed Nov 5, 2026 · Acceleration, Driver assistance · CA

2018 Tesla Model 3, VIN [XXX]. Rear-right ABS wheel speed sensor failed 3–4 days after Tesla Burbank replaced it on XXX (invoice XXX). First alerts XXX (ABS disabled, Drive with caution, TPMS). Failure confirmed XXX (AEB unavailable). Returned from vacation XXX; Tesla replaced same part again (invoice XXX $167.76). Tesla notes state only that sensor “was cut”; no animal damage recorded.I photographed the failed sensor XXX. It shows a single clean angled cut through the black jacket with conductor and red insulation on the same flat face. No tooth marks, scalloped bites, shredded insulation, or nesting material — a shear, not rodent damage.Service Manager [XXX] first blamed a rabbit, then wrote it “was an example” and that Tesla does not need droppings, nesting, or chew marks to call a severed harness outside damage. He has no photos from the 8/18 install; the tech is on leave. Two emails to [XXX] went unanswered. Related BAR complaint filed (ref XXX).Rear wheel speed sensor feeds ABS, traction control, and Automatic Emergency Braking. Failure disables these safety systems. A part that fails days after Tesla service with an undocumented “cut,” followed by a warranty denial based on inference rather than evidence, indicates possible workmanship or installation issues that could affect other vehicles. Requesting the federal safety agency review of Tesla’s service practices for this component.Tesla Service Burbank, [XXX], [XXX].

All 4 Brake lines (tubes) from either from ABS or Brake booster pump are corroded and pierced. All brake fluid leaked front center of the vehicle and lost all brake. Brake lines or tubes are looks good from under the front and back tires. It looks like a quality of the brake lines / tubes from ABS to the bottom are not meeting the expected quality.

I may have figured out the common link between Tesla Autopilot crashes. Distracted operators have the accelerator pressed while the TACC is engaged, thinking (for many reasons) that the vehicle will stop if there are any obstacles in front of them. However, when the accelerator is being pressed, the vehicle will not stop. It will happily run into a wall. One second before impact, the forward collision warning turns on, followed by the ABS and the slamming of the brakes, but by then it's too late for a distracted driver. The raw Tesla "Vehicle Data" on Column D, shows "Accelerator Pedal Position (%)." I strongly encourage you to take a look at the data for the autopilot crashes and review this column to see how many had the accelerator pressed until 1 second before the accident, even if the autopilot was engaged. The 4/25/24 update to Investigation EA22002 states that in 82% of the crashes, the operator did not apply the brake until <1 second prior to impact. Tesla's Director of Autopilot Software Ashok Elluswamy also made a claim that the vehicle can switch pedals if the accelerator is pressed instead of the brake, and that technology saves 40,000 crashes per year: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have had a series of escalating incidents (see attached pdf) that have each involved the vehicle disabling automatic emergency braking system (ABS), traction control, partial steering control, regenerative braking (for electric vehicle), and most recently experienced complete loss of steering function while reversing as well as an additional warning that my airbag was disabled. Initially I was advised to reset my car since it may be a software glitch similar to a computer or phone needing a restart. After several incidents, I was advised to take it to a service center where I was informed that it was a firmware issues known to tesla, but experienced a critical shut down of my vehicle's performance and safety functions the next day. I have seen been informed that they have replaced the high voltage regulator and the wiring harness. I have not received an update since confirming that they believe the latest repair will make the car whole, safe, and functional.
