The 1978 GMC P Series has 2 recalls, the more serious being a driver's seatbelt anchor bolt that can loosen over time from normal vibration, leaving the belt unable to restrain the driver in a crash. This affects vehicles built with Grumman Olson bodies. The second recall covers speedometers and odometers calibrated in miles rather than kilometers, which does not meet the required federal standard for instrument display.
