Applying the brakes under certain circumstances may not disengage the cruise-control, which “can increase the risk of a crash,” the National Highway Transportation Safety Administration said in its recall notice.
The Mercedes recall affects more than 136,000 vehicles, according to NHTSA. The models involved are certain M-Class vehicles from model years 2000 to 2002 and M-Class AMG vehicles from model years 2000 to 2004.
If your car is on the list, you can call Mercedes-Benz directly at 800-367-6372.
The problem involves pumping the brakes to turn off the cruise control. In some cases, that takes unusually high pressure – far more than drivers expect. They can still disengage the cruise control in other ways, which “remain fully operative,” according to the NHTSA notice.
Instead of pumping the brakes, for example, they can apply them steadily. They can also use the cruise-control stalk to turn off the automatic-speed mechanism.
Still, the company intends to fix the problem. Mercedes dealers will make the repair free of charge, but the company says it doesn’t expect to begin making those repairs until September.
Owners of the affected Mercedes vehicles can also call the NHTSA hotline at 888-327-4236.
