Owner reports

Selected complaints filed with NHTSA by 2002 GMC Envoy owners, lightly cleaned up (personal details are redacted by NHTSA).

I began to have issues with my headlights, low and high beams, flickering off and on at random for about 4 months until my brake lights started to do the exact same 7 months ago and now they have quit working all together! I have taken this SUV to 4 different shops now, and nobody has been able to figure out why this is happening. The last mechanic who attempted to fix the issue, says he found an older recall on the original manufactured tag lights being malfunctioned to the point it causes issues with the front and back lights. The man shown me the information on this recall, seeing the part # is listed on there, I compared it to mine and a neighbor's 2002 Envoy; which both of our envoys have these malfunctioned parts. GM has not contacted us back, and we're at a loss because it's a part needed from them directly. …
