General Motors issued a recall for nearly 340,000 of its popular full-size sport-utility vehicles due to problems with their daytime running lights.
According to the National Highway Traffic Safety Administration, the daytime running lights, or DRLs, may not shut off when the vehicle’s regular headlights kick on. The two lights on can create glare making it difficult for other drivers to see, potentially leading to collisions.
“GM determined that the body control module (BCM) software in these vehicles, under a combination of certain pre-conditions, may fail to deactivate the DRLs when the headlamps are on,” GM’s recall report said.
“A regulatory assessment was conducted to evaluate whether the condition presented a potential noncompliance with the DRL activation requirements in S7.10.5, Table I-a. of FMVSS 108. On October 27, 2022, GM’s Safety Field Action Decision Authority (SFADA) decided to conduct a recall for potential noncompliance with this standard.”
The recall covers the 2021 model year GMC Yukon and Yukon XL, 2021 Chevrolet Tahoe and Suburban, and 2021 Cadillac Escalade and Escalade ESV.
GM notes all models produced within that operating window include the improperly programmed body control module, thus all vehicles within that date range may exhibit the problem. The issue was discovered by a GM engineer during validation testing in August, which prompted an investigation and ultimately the recall.
The company says it has no reports of any crashes or injuries caused by the problem.
Dealers will update software that controls the lights. Owners will be notified by mail starting Dec. 19.
