What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1986 Chevrolet Suburban, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

THE LOCATION OF THE WIRING HARNESS, IN GENERAL, AND ITS LOCATION TO THE FUEL TANK IN A REAR END ACCIDENT WOULD MASH THE HARNESS BETWEEN THE BUMPER AND THE FUEL TANK. IF RUPTURE OCCURS THEN THE IGNITION SOURCE WOULD BE PRESENT, RESULTING INTO AN EXPLOSION. *AK

PLEASE INVESTIGATE THE POTENTIAL OF FIRE/EXPLOSION CONCERNING THE FUEL TANK SENDING UNIT (IN OLDER MODEL G.M. VEHICLES) AND THE POSSIBILITY OF A "DIRECT SHORT" TO IT'S WIRING. I BELIEVE THIS COULD BE A SERIOUS SAFETY ISSUE. *AK

I HAVE A COMPLAINT REGARDING BOOSTER SEATS AND THE INABILITY TO PROPERLY SECURE MY 50 LB FOUR YEAR OLD. SHE IS TOO BIG FOR A 5 POINT HARNESS CAR SEAT (40 LBS) AND THERE ARE NO SHOULDER BELTS IN MY 1986 SUBURBAN TO USE A HIGH BACK BOOSTER SEAT. I CAN NOT COMPLY WITH THE NEW CALIFORNIA LAW AND AS A LOW INCOME FAMILY WE CANNOT AFFORD A NEW SUBURBAN FOR OUR 5 CHILDREN! WHAT ARE WE SUPPOSED TO DO????
