This lawsuit, which was first reported on by Car Complaints, was filed in the U.S. District Court for the Southern District of Florida by a plaintiff named Rhonda Small. The plaintiff claims the factory taillights in their K2XX-platform GMC Yukon have faulty LED light strips that may cause the brake and/or taillights to fail. These lights may also have a faulty connection inside the light assembly or a defective circuit board, which can lead to similar issues with the brake and taillights.
GM issued a Technical Service Bulletin (TSB) in November of 2019 for certain 2015-2016 model year GMC Yukon SUVs to address a problem with these vehicles’ taillights. The TSB, entitled “Tail Lamps Inoperative,” indicated the stop and tail functions inside the taillamps may experience various issues and instructed dealers “to replace tail lamps if they are found to be inoperative.” The class action lawsuit says later model year GMC Yukon vehicles should have been included in this TSB, which only involved 2015 and 2016 model year vehicles.
As noted by Car Complaints, the plaintiff says the problems with the taillights can be traced back to the “defective design of the alloy base circuit used to maintain continuity,” in the taillights of affected vehicles.
“The alloy’s inability to expand and contract due to the current design causes the Tail Lamp Assembly Defect, whereby the alloy breaks, interrupts the current from maintaining continuity, and results in failure when the circuit trace inside the housing cracks,” the lawsuit says. “The tail lamp assembly should have had expansion and contraction points to prevent premature failure.”
This lawsuit also says the taillights can experience similar issues if enough moisture is allowed to enter the light assembly. If this condition occurs, owners may also observe moisture or a clear white film forming on the inside of the taillight lense(s).
The plaintiff claims GM has actively tried to hide these defects and has left GMC Yukon owners on the hook for costly repairs. The filing also alleges this problem is so widespread that it has led to a backorder of replacement parts across the country.
