A class action lawsuit has been filed against GM alleging that the Detroit-based automaker ignored its California emissions warranty obligations regarding active grille shutters found on several of its products.
According to a report from CarComplaints, the lawsuit claims that only states that have adopted California’s low-emission vehicle ‘criteria pollutant and greenhouse gas (GHG) emission regulations and Zero Emission Vehicle (ZEV) regulations under Section 177 of the Clean Air Act’ are included in the active grille shutter emissions lawsuit. As such, vehicles equipped with active grille shutters should be covered under the seven-year, 70,000-mile California emissions warranty as high-priced parts.
However, an owner of a 2017 GMC Sierra 1500 alleges that they were denied coverage by General Motors due to the automaker failing to perform a high-priced analysis that complies with the California emissions warranty. Essentially, the lawsuit claims that consumers are paying for active grille shutter repairs when they should be covered under the warranty.
While GM technicians did perform a free software update referencing technical service bulletin 18-NA-037, the plaintiff is arguing that the update didn’t correct the problem. Later on, a tech found diagnostic trouble code (DTC) U1510, which indicated a defective active grill shutter. The shutter was then replaced for $331.50.
“GM failed to cover the repair or replacement of the grille shutter part under the California Emissions Warranty either because GM failed to perform any high-priced calculation for this part or because GM used the ‘warranty pay rate,’ instead of the ‘consumer pay rate,’ to perform the high-priced calculation,” the class action lawsuit reads.
The list of vehicles included in this lawsuit includes:
- 2017-2019 Chevy Silverado
- 2017-2019 Chevy Suburban
- 2017-2019 GMC Sierra
- 2017-2019 GMC Yukon
- 2017-2019 Cadillac Escalade
According to the plaintiff, The General has been using the wrong standard for calculating the labor cost when determining whether a part is considered a ‘high-priced part’ per California regulations.
