What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 1999 GMC Envoy, 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.

NAR 1/29/2003. THE CONSUMER STATED THE VEHICLE HAS ELECTRICAL AND TRANSMISSION PROBLEMS. THE PASSENGER REAR VIEW MIRROR ROTATED TOWARD THE FRONT OF THE VEHICLE WITHOUT ANY OUTSIDE ACTION. THE WINDSHIELD WIPERS CHANGED THE WIPING SEQUENCE AT ITS FREE WILL. THE DOORS LOCKED ON THEIR OWN AND THE WINDOWS ROLLED DOWN ON THEIR OWN. THE CONSUMER WAS UNABLE TO SHIFT INTO 1ST OR 2ND GEAR REGARDLESS OF WHETHER THE VEHICLE WAS IN 2 OR 4-WHEEL DRIVE. THE DEALER ADVISED THE SHIFTER WAS DEFECTIVE. *JB

Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
THE LOW BEAM HEADLAMPS ARE XENON BULBS, AND COST OVER $700 EACH TO REPLACE. I BELIEVE HEADLAMPS ARE A SAFETY ISSUE AND SHOULD BE REASONABLY PRICED. MERCEDES ARE OVER $1200 EACH, AND BMW OVER $800. I'M AN AUTO MECHANIC AND SEE QUITE A FEW FAILURES, AND EACH TIME THE CUSTOMER DENIES THE WORK AND DRIVES ON 1 HEADLAMP, OR LEAVES THE HIGH BEAMS ON. I FEEL THERE SHOULD BE AN ALTERNATIVE REPLACEMENT, OR PRICE RESTRUCTURING ON THE DEALERS PART.*AK

Powertrain (other)

From owner reports, verbatim
THE PROBLEM STARTED OVER FIVE WEEKS AGO. THE CAR WOULD NOT START ONCE I PUT IT IN PARK. I'VE HAD THE PARK NEUTRAL SENSOR SWITCHED CHANGED AND EVERY TIME IT HAPPENS WHICH IS AFTER THE FORTH OR FIFTH TIME I PUT IT IN PARK. I'VE HAD THE CALLED TOWED OVER 10 TIMES AND MY INSURANCE HAS BEEN CANCELED BECAUSE OF IT. THE DEALERSHIP JUST KEEP TIGHTENING THE GEAR SHIFT BUT AS I SAID WHEN I DRIVE IT, IT LOOSEN UP AND THE SAME THING HAPPENS. I THINK IT DOESN'T START BECAUSE THE SECURITY SYSTEMS KICKS IN WHEN I TRY TO PUT THE CAR IN GEAR. *TR
