When it comes to vehicle safety, every component plays a crucial role in ensuring a smooth and secure ride. Recently, General Motors (GM) discovered a potential issue with improperly heat-treated suspension bolts in select Cadillac, Chevrolet, and GMC vehicles. This problem, if left unaddressed, could lead to serious safety concerns, including misaligned rear wheels and an increased risk of accidents.
In August 2023, a plant quality manager at GM’s Arlington, TX assembly plant uncovered a concerning issue. They identified that as many as 223 vehicles may have received improperly heat-treated bolts during the manufacturing process. Unfortunately, these vehicles were not contained at the plant, which raised alarm bells. Of the affected vehicles, 189 were located in the United States.
In response to this discovery, GM initiated a comprehensive investigation into the issue. Extensive testing and analysis were conducted to determine the potential consequences of these improperly heat-treated bolts. What they found was alarming: in the event of a control arm separation, there was a distinct possibility of rear wheel misalignment that could adversely affect the vehicle’s handling.
It is worth noting that, up to this point, GM had not received any reports of field incidents related to this condition. Recognizing the potential risks associated with the improperly heat-treated suspension bolts, GM’s Safety Field Action Decision Authority (SFADA) made a decision in September to conduct a safety recall to address the issue.
The vehicles affected by this recall include the following 2023 models:
- Cadillac Escalade
- Cadillac Escalade ESV
- Chevrolet Suburban
- Chevrolet Tahoe
- GMC Yukon
- GMC Yukon XL
If you own one of the aforementioned vehicles and receive a recall notice, it is crucial to act promptly. GM will ask you to return to your authorized dealer to have both rear suspension outer control arm bolts replaced. This proactive step is vital to ensure your safety and the proper functioning of your vehicle. To facilitate this process, GM has assigned a unique recall number for this issue, N232415910, and the National Highway Traffic Safety Administration (NHTSA) has assigned the campaign number 23V-642.
