1999 GMC Suburban 1500 Problems
The anti-lock brake system (ABS) front wheel speed sensors are prone to failure. When a sensor fails, the ABS warning light may illuminate and/or the ABS system may activate erratically.
The power door lock actuators may become slow to operate or stop working completely and require replacement.
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Running the engine with a coolant/oil mix may result in engine damage. Replacing the intake manifold gasket should correct this issue.
The quick-connect fittings for the heater hoses tend to leak engine coolant. This problem commonly occurs because the metal housing has become brittle, which can break and cause leaks.

I haven't had any problems with the truck as a second vehicle I had over 190,000 miles on it when I got it. It fits the old family and it keeps them quiet with the tv and sound system in the back.
typical gm quality, the doorhandles break, heater work when it wants to and has no safety features for children other than front control door locks. front end goes out and breaks dont hold up. the motor on other hand has 160,000 and runs like new. be nice to get out of a big rig without rolling window down in winter.
Basically a safe vehicle but typical GM poor quality; door handle fell off, plastic interior parts broke easily, A/C compressor went out at 52,000 mi., door light spring switch fell off, right turn signal doesn't cancel, daytime running lamps no longer operational AND most importantly the BRAKE SYSTEM ANTILOCK SENSOR IS MALFUNCTIONING. Next time, go to Honda or Toyota
