Airbag Issue in Tesla Model S and Model X

Posted on by

Tesla has identified a significant safety issue affecting certain 2021-2023 Tesla Model S and Model X vehicles. The problem lies in the installation of incorrect steering wheel airbags during vehicle servicing. This issue predominantly arose during the retrofitting of vehicles with alternate steering wheels based on customer requests.

Discovery of the Issue

The problem came to Tesla’s attention in October 2023, when Tesla Service in Europe encountered 12 instances where vehicles with round steering wheels were retrofitted with yoke steering wheels. However, there was no confirmation of the appropriate driver airbag variant installation for the yoke steering wheels. This prompted Tesla to initiate an engineering study in the U.S., encompassing 10 vehicles. Of the three vehicles inspected, one was found to have the wrong driver airbag variant, meant for the round steering wheel.

The Nature of the Problem

At the core of this issue is the mismatch between the steering wheel design and the driver airbag variant. The round steering wheel and the yoke steering wheel each require a distinct driver airbag design. During servicing, some vehicles were erroneously equipped with a driver airbag variant mismatched to the steering wheel type. This discrepancy can potentially compromise airbag performance during deployment, elevating the risk of injury in the event of a collision.

2020-2023 Ford Mustang No Low Brake Fluid Warning

Posted on by

brake light warningSome Mustang cars made between 2020 and 2023 have a problem with their brake fluid level sensor. This sensor doesn’t activate a warning light when the brake fluid is low. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standards for light vehicle brake systems.

Ford became aware of the problem in August 2023 when an issue pertaining to 2020-2023 model year Mustang brake fluid level warning systems was brought into Ford’s Critical Concern Review Group (CCRG) for review. They discovered that the problem lies with the Body Control Module (BCM), a part that manages the brake fluid sensor. This BCM should turn on the brake warning light if there’s a problem. In Mustangs made from 2018 to 2023, the brake fluid sensor is directly connected to the BCM. However, in the 2020 Mustang, they switched to a different BCM design, called “Gen1m,” which incorrectly looks for a message from the brake fluid sensor over a network (CAN) instead of the direct connection.

After investigating, Ford confirmed that this problem only affects Mustangs from 2020 to 2023. They also verified that the 2024 Mustang doesn’t have this issue because the brake system and BCM are set up correctly. The Brake Development team tested Mustangs from 2019 to 2024 and found that the 2020 to 2023 models fail to meet the requirements for warning about low brake fluid. However, these vehicles meet all other brake system warning lamp requirements.

Ford initially didn’t run certification tests on the 2020 to 2023 Mustangs because they thought the brake system was the same as in the 2018 model. They didn’t know that the BCM was incorrectly configured to use a network message.

As of September 12, 2023, Ford received 123 warranty claims related to a brake fluid loss on these vehicles, but there were no reports of the brake fluid level sensor not working.

To fix the problem, Ford dealers will update the software in the body control module. They plan to send out initial letters in December 2023 to notify owners about the safety issue and will send second letters when the solution is available. This recall is identified by Ford as number 23C35, and the NHTSA campaign number is 23V-727.
