General Motors, LLC (GM) is recalling certain 2023 Chevrolet Silverado 1500, GMC Sierra 1500, 2023-2024 Chevrolet Tahoe, Suburban, GMC Yukon, Yukon XL, Cadillac Escalade, and Escalade ESV vehicles. The electronic brake control module software may fail to display a warning light when a loss of brake fluid occurs. As such, these vehicles fail to comply with the requirements of Federal Vehicle Safety Standard number 135, "Light Vehicle Brake Systems."
General Motors, LLC (GM) is recalling certain 2023 Cadillac Escalade, Escalade ESV, Chevrolet Suburban, Chevrolet Tahoe, GMC Yukon, and Yukon XL vehicles. The rear suspension outer control arm bolts may not have been properly heat-treated, which can cause the bolts to break.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“After the original engine failed the recall inspection, it was replaced as part of GM's recall program at 40k miles. At 50k miles with the new engine (so only 10k miles into the new engine), the engine completely locked up and shut down while my son was driving the car on the interstate. We had to get it towed to the nearest dealership, and two weeks later, we are still waiting on the engine to be replaced again under warranty. I have completely lost faith in this car as I will now be on my third engine in 50k miles, and it is very dangerous if this thing can just shut down again while driving as they clearly have not solved the issue of these failing engines.”
“Initially the vehicle was slowing at a moderate pace from 75-40mph while on the freeway during [XXX] rush hour. Two days later after getting off the interstate, the rear wheels locked up while doing 40mph on a side street for approx. 1.5seconds. If this had happened on the freeway it would have caused an accident or loss of control. The dealer inspected the vehicle, recreated the issue, and stated the valve body valves were sticking and needed replacement. We never got any warning lights, nor did the dealer before and after they recreated the issue.”
“I have a 2023 GMC Yukon SLT. The OnStar/telematics system stopped working. The blue OnStar button does not function, and the vehicle no longer communicates with the myGMC app, resulting in the loss of OnStar and connected services. A GMC dealership diagnosed a failed OnStar/telematics module and advised that replacement will cost approximately $1,200. This creates a safety concern because OnStar provides emergency services, including Automatic Crash Response and the ability to request emergency assistance from inside the vehicle. A module failure could leave an occupant without access to these services when they are needed most. I am also concerned that OnStar and telematics failures appear to be reported by owners of multiple GM vehicles, suggesting this may not be an isolated failure. I am requesting that this issue and similar complaints be investigated to determine whether there is a broader defect requiring a recall, warranty extension, service campaign, or other corrective action.”
