2005 GMC Envoy: headlights failing or too dim

Filed Jun 1, 2019 · Lights · 122,250 miles · CA

About 4 years I noticed my low beam headlights sometimes would not work at night, forcing me to drive with my high beams on, blinding other motorists. This was reported to the dealer's service manager and he said it may cost $500 to determine the cause. I could not afford this expenditure. I try to avoid driving at night and only recently I had to drive at night and again my low beams would not work, forcing me to again drive with my high beams on. My fianc did a google search and learned this is a common problem with this fuse/relay. We learned we could pull out the high beam fuse/relay which is identical to the low beam and switch them. Upon doing so, the low beams once again worked.

I had just drove my truck the night before headlights worked fine. I went to leave the next night and no headlights at all. So vehicle was stationary when I realized I had no headlights. I have to drive with my brights on at night. I have no regular headlights at all. Then my passenger side window just quit working as well.

A while back, we noticed while driving down the interstate at night that our lights seemed to be flickering (low beams). It would do it occasionally, but we never knew when it would happen. Since then, we have had the lights go completely out while driving, and had to turn the fog lamps on to have headlights of any sort. Tonight, the lights went out, and I pulled into my driveway and was going to have my husband come out and see what was going on if he could. While I sat there with the car running and in park, after about 3 minutes, they came back on. I have read that there was a recall on the light modular for 2006+ envoys, but mine is a 2005, and having the same problem that I heard the recall was for. I have also heard that the 2005 trailblazers were included in the recall, but not the envoys????

The low beam headlights went out while driving 50mph on a highway because a relay in the fuse box overheated and melted the fuse box. I know there is already a recall on the trailblazer from the same year because they are the same car but there is not one for the envoy.

Low beam headlights go off without warning. High beams still work. This has happened when moving on city roads and highways. The next time I drive the car the low beams may or may not work.

Tl* the contact owns a 2005 gmc envoy. The contact stated that the exterior low beam headlamp failed without warning. The dealer was not contacted. The contact previously replaced the headlamp relay independently, but the failure occurred approximately three times. The manufacturer was notified of the failure. The failure mileage was 124,000.

The vehicles headlights keep going out at night will driving. I have been dealing with this problem for about 2 years, I am a certified mechanic and I believe the problem is the headlight relay that is overheating. This is the same gm part that is being recalled in other gm vehicles. Gm part # 15016745. So why has it not been recalled in 05 . The problem happens at random the light will go out while driving or parked it does not matter.

I've had my 2005 envoy for a little over a year and had my headlights flash on and off while driving on the road and freway. On one occasion while driving on a two lane highway ay night the lights went out completely for a few seconds. I was so scared wss really glad for no one behind me or on coming traffic. On another occassion I had to pull over on city street as my lights were going on and off and I could see the car ahead was a cop and I didnt want him to think I was flashing for help especially at 2 in the morning. Ive also had to exit the freeway because my lights started going on and off and on and wasnt sure if they would just go out completely while I was driving and since it was night time I didnt want to take the chance of causing an accident and hurting someone else or myself. I have a teenage daughter and am afraid to transport her and her friends in my car.

Reading numerous complaints that compare to mine the fuel gauge, oil gauges, air conditioner are all malfunctioning in my car and I'm very upset because all of this should have been recalled. I purchased my car brand new in 2005 and I will never buy a gmc car again for this reason it's one thing to recall repair parts that were broken that to repair malfunction parts. Very disappointed. In short my gauges don't work, my air conditioner only works on one side and now my headlights low bean don't work. Gmc needs to recall and repair.

I was driving down the highway after dark and my low beams completely went out. I could only get my high beams to work. Currently only one low beam is working and the other will not work even after changing the bulb or the fuse. I believe this is a huge safety concern especially having a young child. It was very scary going down the road at night and have your lights completely just go out. I have noticed that there are issues with 06-07 envoys but I wanted gm to be made aware that 2005 models have been affected as well.
