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

Each component in detail
What the reports in each category say, in the owners' own words
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
WHILE RETURNING HOME FROM WORK TODAY I APPROACHED A TRAFFIC LIGHT, PRESSED ON THE BRAKE PEDAL AND MY FOOT WENT STRAIGHT TO THE FLOOR. I HAD TO TURN INTO THE GRASS MEDIAN TO AVOID HITTING THE CARS IN FRONT AS I PRESSED THE EMERGENCY MANUAL BRAKE. BECAUSE I WAS VERY CLOSE TO HOME AT THAT POINT I WAS ABLE TO CONTINUE DRIVING WHILE USING THE EMERGENCY BRAKE TO STOP. I CHECKED THE BRAKE FLUID LEVEL AND IT WAS WITHIN NORMAL RANGE. *TR
ANTI-LOCK BRAKING SYSTEM ENGAGES WHEN COMING TO A STOP CAUSING VEHICLE TO TAKE LONGER THAN EXPECTED TO COME TO A STOP. I HAVE HAD SEVERAL NEAR ACCIDENTS INCLUDING ALMOST STRIKING A PEDESTRIAN. *JB

I PURCHASED A 1999 YUKON DENALI FROM MY FORMER BROTHER N LAW; HE DIDN'T INFORM ME THAT MY WINDOWS, DOOR LOCKS, RADIO,AND WINDSHIELD WIPERS WOULD STOP WORKING. I WAS TOLD THAT I NEEDED A BODY CONTROL MODULE; ONE GMC MECHANIC ASKED ME WHAT DOES THIS PART DO. I'M A LADY HOW WOULD I KNOW THESE THINGS. I STILL DON'T HAVE MY VEHICLE REPAIRED. WILL THIS CAUSE ME OTHER PROBLEMS OR CAN I CONTINUE TO DRIVE OFF A WING AND A PRAYER? *TR
ON APRIL 4, 2006 AT APPROX. 5:00PM OUR 1999 DENALI GMC CAUGHT FIRE AND WAS DESTROYED. IT STARTED TO LOSE POWER AND THEN IMMEDIATELY BURST INTO FLAMES AND WAS A TOTAL LOSS. I FEEL THIS WAS A MANUFACTURE DEFECT OF SOME KIND AND WOULD LIKE TO HAVE THIS INVESTIGATED. I DO HAVE PICTURES TO PROVIDE YOU. *JB
