1988 GMC SUBURBAN Recalls — Canada & USA

The 1988 GMC Suburban has 3 recalls, with two tied for most serious: corroding front brake rotors that can separate and cause sudden partial loss of front braking, and automatic transmission fluid that can leak onto hot engine components and start a fire. The brake concern applies to vehicles with composite front rotors, where corrosion causes the steel center section to break away from the cast outer rotor, cutting braking force at that wheel without warning. On the fire side, this recall covers two-wheel and four-wheel drive models with automatic transmissions, where abnormal pressure buildup in the transmission can push fluid out of the filler tube onto hot engine parts. There is also a restraint concern: the driver's seat shoulder belt locking mechanism may not function, and in a crash the belt may fail to hold the driver in place, raising the risk of injury.
