Cadillac Lyriq Under Investigation for ABS Failure

The issues at hand relate to the Lyriq’s anti-lock brakes and, in particular, the internal electronic brake control module at risk of breaking when the ABS is active. The department says that no injuries or deaths occurred as a result of the defect, and overall, 3,322 2023 model year vehicles are implicated in this investigation. If the module breaks, the automaker will report that ABS performance will be affected, and drivers can expect a “Brake System Failure” warning in their digital instrument clusters.

For now, officials are only looking at the owners’ claims to determine the “extent and severity” of the problem. GM is reportedly releasing an update over the air to get ahead of things, according to NHTSA. Continuing ODIs, although the new software will definitely not fix the unreliable module. Instead, it is designed to alert drivers when starting the car specifically if a part breaks. This wouldn’t seem very helpful, given that the existing “Brake System Failure” message certainly does a good job of conveying that something is already wrong, but at least it could warn drivers before they hit the road – not to mention save the mechanics when the battered Lyriq comes in in the service bay.

Given that no 2024 vehicles are currently part of the NHTSA investigation, it appears that the defect is localized to previously driven Lyriqs that used a different material in their spindles. That is indeed good news. After the Chevrolet Blazer EV’s complex program took the design off the rails for months, GM can’t afford to let another of its flagship EVs sit idle for too long. Especially if it is expected eventually start turning a profit on such vehicles as soon as next year.
