1999 GMC Suburban 1500 Problems

ABS Front Wheel Speed Sensors May Fail

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.

Check Engine Light With Code P1870

Vehicles equipped whit a 4 speed automatic transmission may develop a harsh 1-2 shift and/or illumination of the Check Engine Light with code P1870 stored. This can be caused by wear of the bore for the TCC isolator and regulator valves in the valve body. This condition does not commonly occur until the transmission reaches normal operating temperature. If the valve body is worn, replacement will be necessary to correct this concern.

Check Engine Light and Misfire Due to Stuck Fuel Injectors

One or more fuel injectors may become stuck closed causing an engine misfire  and the Check Engine Light to illuminate. Our technicians tell us that this problem can be caused by some fuel additives. There are special procedures which may be able to restore the affected injector. If this fails the affected injector must be replaced.

When making a left turn or going around a turn toward the left the steering will lock for a few seconds then release. You can feel a jerk when it releases. I have had upper ball joints replaced and had an alignment recently. What would cause this?

1999 GMC Suburban 1500 Reviews

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
