2015 Tesla Model S: ABS light or ABS activating

Filed Feb 21, 2023 · IN

I had the eMMC replaced under recall in December of 2021. The board failed again in December of 2022 resulting in all controls of the car being inaccessible, the center screen was black. I had no control of lights or HVAC and all the traction control, ABS, and emergency avoidance features were not working. Tesla told me there was no fix except to upgrade to the MCU2 computer which cost me $1,872. This was related to the original recall that didn't really fix the problem. The MCU just went dead, no waring.

Wheel speed sensor kept getting disconnected. When it does, systems like ABS, traction control, and other anti-collisions systems are disabled immediately. This resulted in lost of vehicle control on wet pavement. The service center replaced the sensor twice but the problem continues to pop up randomly. They won’t look at the issue unless I pay for troubleshooting at $150/hr with no limit of how long or if they will find something.

System Failure: Adaptive speed control Safety Risk: My 2015 Tesla Model S, at highway speeds, smashed into the rear of a jacked up Ford F250 Pickup. A Head on collision at highway speeds put my wife (and dog) and I at great risk. Has the problem been reproduced or confirmed by a dealer or independent service center? I am unsure if or how Tesla is dealing with the problem of adaptable speed control failure. Has the vehicle been inspected? Yes. Dan's Paint & Autobody and USAA Insurance Company adjuster My accident happened in the southbound passing lane at mile marker 178 on I-10, south of chandler on the Gila River Community in Maricopa/Pinal County It was dark outside with heavy traffic in both southbound lanes. My software version was 2021.40.6 I had the distance between cars at the closest setting , and had the adaptive speed control set at ~75. I was attentive with both hands on the wheel, eyes forward watching traffic with my wife whom was also watching the traffic. Without warning a Ford F250 stopped hard in front of me and my adaptive speed control did not react. The few beats I gave the adaptive speed control to respond first cost me precious braking time. I did hit my abs brakes and could feel the vibration as they attempted to slow down, but it was too late. I submarined under the bumper of the truck at a very high speed. There was no warning lamps, messages at the time of the accident. There was one early symptom that I recall. There was a Tesla software update a few days before the collision. On 11/27/22 before leaving for my trip, the dash screen to the far left did not display the map which it usually does when you set the GPS to map the path. I rebooted with the steering wheel toggles, and the display returned to normal. There were no other software malfunctions that I recall prior to the adaptive speed control failure.

Please note: the VIN of the actual car that is the subject of this complaint is unavailable therefore I have used the VIN of another tesla of the same year and model in order to be able to make this submission. This complaint is about suspension failures in teslas. Here is a tesla in a salvage auction in england. Https://www.copart.co.uk/lot/37735131/clean-title-2015-tesl-model-s-p8-wolverhampton the only damage to the car is that the front wheel and suspension has been wrenched off. No air-bags have deployed and there is no impact damage anywhere on the bodywork. Photographs attached with this submission show the broken suspension and detached wheel. I believe that the cause of so many teslas having wrenched off wheels is very simple. Circumstances can occur in which full braking is applied to a wheel but the motor is still at full power. The electronics are not infallible. Glitches can occur. Even if power to the motor is shut down there is still massive stored energy in the rotor of the high RPM electric motor which acts as a massive flywheel. The suspension linkages are not strong enough to withstand the torque which is then applied. It is even worse if the ABS or traction control pulses the brakes because this then gives a hammer blow effect. This failure can affect either the front wheels or the rear wheels. There have been many similar cases of torn-off wheels. You can see examples here https://www.flickr.com/photos/136377865@n05/albums/72157719033036968 please take action. It is obvious that tesla is refusing to remedy the situation.

The media control unit has gone out on my 2015 tesla, which has LED to the car not being able to be recharged (refueled), the AC being unsusable, and car unable to be locked among other issues. With teslas, the media control unit (mcu) is the powerhouse of the vehicle, containing all of the safety, A/C, and driving controls. With this being out of commision, there is no telling what features are usable or not. This leads me to worry about whether the airbags will deploy, whether the car will stop randomly on the freeway, or the car not being refueled. In fact, since this mcu has gone out, the car has not been able to be refuelled due to the mcu not allowing chage to reenter the car. This has lead the car to be unusable and unresponsive. This first occurred for me while diving on a city street, with nothing unusual being noted at the time. The car was responsive, driving normally, and completely usable and out of no where the vehicles mcu went black and the driving features were handicaped. The car was still able to drive, however, A/C components and unknown electrical features (such as airbags, seat belts, ABS) may have been compromised.
