General Motors rolled out the BEV3 unibody electric vehicle platform in 2022. Its first application is the Cadillac Lyriq, which is marginally longer in overall length and wheelbase than the internal combustion-engined XT5. As with every brand-new platform, things can go wrong.
Back in September 2022, the Lyriq was recalled to the tune of 186 vehicles for a blank instrument panel display caused by a software error in the driver video display module. Fast forward to May 2023, and the Lyriq was recalled once again. On said occasion, four units had their high-voltage batteries replaced over incorrectly welded connections.
The latest recall concerning the Lyriq has just been published by the National Highway Traffic Safety Administration. The portable document file attached below reads 62 vehicles that may have been updated with incorrectly calibrated software for the body control module. Said update somehow disabled the pedestrian warning sounds required by federal motor vehicle safety standard number 141 for battery-electric vehicles and hybrid vehicles.
As per documents filed with the federal agency, suspect vehicles fail to emit pedestrian warning sounds while decelerating from 30 to 25 kilometers per hour. Why did Cadillac use metric instead of imperial for a problem concerning the US market? Anyway, that means 18.6 to 15.5 miles per hour.
Rather than General Motors, the peeps at Denso International America provided incorrect calibration values to the GM software calibration management system. The incorrect values were subsequently included in a software update deployed to the 2023 model year Cadillac Lyriq in the period between August 23, 2022 and September 8, 2023.
Affected vehicles were produced from April 7, 2023 through April 20, 2023 at Spring Hill Manufacturing in Tennessee. The only other place where the Lyriq is also made is Shanghai, China.

A quality engineer submitted this issue to General Motors through the Speak Up For Safety program on September 8. The largest automaker of the Big Three in Detroit started investigating on September 22, determining that Denso was to blame for the missing warning sounds. To date, GM hasn’t learned of any field incidents related to said issue.
Dealers have already been instructed to deploy a new software package at no cost whatsoever to the customer. Owners will be informed via first-class mail no later than November 27. GM halted deployment of the flawed update on September 8.
In related news, did you hear the Lyriq launched in Europe at the beginning of October? Said launch marked the Big G’s return to the EU as an EV-only manufacturer. The eight-gen Corvette and soon-to-be-gone Camaro are the only exceptions to GM’s EV-centric philosophy in this part of the world.
Currently exclusive to Switzerland, the Lyriq starts at 82,000 francs or 91,860 freedom eagles at current exchange rates. Prospective customers who place an order today are presented by the online configurator with a tentative delivery date of April/May 2024.
Back home in the United States, the most affordable spec is $58,590 excluding the destination fee. As for the People’s Republic of China, make that 379,700 yuan or 51,920 dollars at current exchange rates.
