The Cadillac Lyriq is a very important vehicle, not just for Cadillac, but for GM as a whole, launching the luxury marque’s first production all-electric product and moving General Motors towards its goal of achieving zero tailpipe emissions across its light-duty vehicle lineup by 2035. Critically, some units of the 2023 Cadillac Lyriq may require a fix for the high-voltage harness, which could rub against the high-voltage battery case, causing damage. Now, GM has issued a service update for affected models.
The new service update only applies to the 2023 Cadillac Lyriq, and includes both customer vehicles and vehicles in dealer inventory. The issue pertains to the crossover’s high-voltage harness, which may be damaged when it comes in contact with a sharp edge on the high-voltage battery case. It’s unclear exactly how many units of the 2023 Cadillac Lyriq may be affected by this issue.
In order to fix the issue, GM is instructing certified GM technicians to apply an “anti-abrasion electrical tape / orange electrical tape” to secure the high voltage harness away from the high voltage battery case. The fix may also require a wire tie-strap. The fix may only be completed at a Cadillac dealer that has met the EV Readiness Requirements, while the technician who performs the fix must have successfully completed all required training.
As GM Authority covered previously, more than 2,000 units of the Cadillac Lyriq have been produced so far during the course of the 2023 calendar year, while deliveries to customers continue to accelerate. It’s estimated that roughly 1,000 units of the Cadillac Lyriq were shipped during the mid-January to mid-February timeframe. Additionally, just 122 Cadillac Lyriq units were delivered during the 2022 calendar year.
For those who may be unaware, the Cadillac Lyriq features GM Ultium batteries and GM Ultium Drive motors, with the GM BEV3 platform providing the underpinnings. Production takes place at the GM Spring Hill plant in Tennessee.
