1 recall across 1 model year
The GMC BUS has 1 recall affecting the 1975 model year, where incorrect wheel bearing adjustments or mispositioned sensors can send false signals to the anti-lock brake computer, causing the system to believe a wheel lockup is occurring when it is not. When the computer receives these erroneous signals, it can trigger the anti-lock system unnecessarily, interfering with normal braking and potentially reducing the driver's ability to stop the vehicle as expected.
