Headlights problems of the 2005 GMC Envoy

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.

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.

Tl-the contact owns a 2005 GMC Envoy. The contact stated that while driving, the contact noticed that the front passenger head light flickered and then failed. An independent mechanic replaced the headlight and fuse but the failure persisted. The contact stated that while driving, the front driver head light flickered and then failed. The vehicle was taken to an independent mechanic but the failure could not be duplicated. The manufacturer was made aware of the failure. The approximate failure mileage was 133,000. Sms.

The first day we had the truck the speedometer displayed the wrong speed and has been that way. It works occasionally. Then a week later the low beam head lights went out while driving. They came back on after a few mins. This happened again a few days ago. The fuel gage is in accurate as well. I took it to a shop and they said the instrument cluster needs to be replaced but found no issues with the head lights but there is deffinately an issue with the headlights and that is very dangerous.

The very same thing described in nhsta campaign 14v755000, gm safety recall 14291, began happening to my 2005 GMC Envoy xl. My headlights flickered off and on. In time, my headlights stayed off longer and longer. Only the low beams and the daytime running lights seemed to be affected. I could find no discernible reason or connection to any action or setting on the car. When the lights go out when I am driving at night and remain off for more than a second or two, it is very dangerous, so I quit driving at night in this vehicle and have taken it to a gm service center for repair. .

While I was driving on the ramp, my headlights started to flicker in and out. At one point the lights went completely out. After hitting a bump in the road the lights came back on. Went to the mechanic and they were not able to find anything wrong.

On way driving down the road at 8:00 pm central time at night to mothers house at speed of 45 mph which is speed limit 55 mph. All of a sudden while driving, the headlights start flickering on and off. As I still driving, the headlights flickering on and off got worse and worsier. I was immediately concern with the safety of myself and other drivers on the road that I had to stop at a store to check the lights. Lights and vehicle is intact and nothing seem to cause any obstruction for the lights to flicker on and off. I immediately came home which I was only 15 miles from the house.

My problem is covered under recall 14291 but my year isn't included. Despite numerous bulb replacements and mechanic visits, my vehicle's low-beam headlights do not work. I've contacted gm, but they offered no solution that's affordable. I have no headlight other than high-beams. Please help and make gm investigate this problem on all their 2005 model year vehicles.

The contact owns a 2005 GMC Envoy. While driving approximately 30 mph, both of the low beam headlights intermittently shut off without warning. The failure recurred on several occasions. The vehicle was not diagnosed or repaired. The manufacturer was not notified. The approximate failure mileage was 90,000.

Headlights began to dim, then brighten repeatedly, as to appear to be "flashing" other drivers. Shortly after, the oil pressure gauge malfunctioned. After the oil pressure gauge, a few days later the battery gauge malfunctioned. A few weeks later, the gas gauge stopped working right. Now, the engine continuously jerks, like it is missing due to lack of fuel. Contacted GMC on 11-09-2012. No solution.

The contact owns a 2005 GMC Envoy. He stated that the headlights, dashboard lights and rear lights shut off while driving approximately 35 mph or various speeds. The high beams immediately activate when the headlights shut off which distracts drivers. The failure mileage was 28000 and the current mileage was 58000.

Sporadic failure of speedometer - registers correctly one moment, or may read 30 mph or 0 mpg when keeping with the flow of traffic on the interstate. While this does not occur each trip, it does occur several times each week. Fuel gauge malfunction - reads one-half tank at 179 miles; 20 miles later reads one-quarter tank. Issues "fuel level low" warning after refueling and for next 3 to 4 times vehicle is started headlights dim briefly when accelerator is released. Frequent need to replace exterior lamps the problems first manifest in the need to repeatedly change brake and taillight bulbs, and the dimming of the headlights, which continues. Then, sporadically, the speedometer stopped functioning, or only registered a fraction of the speed the vehicle was traveling. After that, at start up, the "fuel level low" warning, which activates when the vehicle determines it has fuel to travel 40 additional miles, started to chime when there was more than one-half tank of fuel. The warning also now issues whenever the vehicle is refueled. The potential failure of the exterior lighting system presents a clear hazard to the occupants of the vehicle and others - the driver wouldn't be able to see where he is going, and other drivers wouldn't be able to see the vehicle heading toward them. The fuel system issues could lead to unexpectedly running out of fuel, creating the potential for a disabled vehicle or its driver being hit by another. In addition, depending on the cause of the malfunction, the vehicle could be susceptible to fire. Without a functioning speedometer, the driver can easily travel too fast for conditions, or endanger himself and others in a construction zone. Currently, until the sporadic problems become regular, the garage will not fix the vehicle.

At various time, especially when depressing the brake pedal, the headlights and interior lights dim. Gm knows about the problem - tsbs 05-08-42-001 and 06-06-03-004 but does not have a fix. This is a safety issue and needs to be addressed. Updated 10/23/07.

I purchased a 2005 GMC Envoy in September 2005. In the past year (since January 2007, at least), I have experienced several problems with my vehicle. The first problem is with the headlights. Everytime I have driven the vehicle the headlights appear to dim/flicker and then return to normal. This has resulted in oncoming vehicles turning their bright lights on me thinking my brights are on when in reality my headlights are dimming and then returning to normal. The second problem concerns the passenger side airbag. Anytime a certain weight limit is met or exceeded the airbag sensor is supposed to switch to on, but there have been several occasions when someone was sitting in the passenger seat and the airbag sensor hasn't recognized it. Third problem, driver side power seat failure. There have been several instances when I have tried to move the driver seat forward, but nothing happened. The motor sounded like it was grinding and wanted to move, but the seat would not move forward or backward. The most extreme problem to date has been with the vehicle completely shutting off without warning while in the middle of driving and then not starting or even turning over at all. Every single day for, at least, the last month when I go to start the vehicle it fails to start and it takes a minimum of 1 hour to get it started. One instance in particular when the vehicle shut off without warning was while my wife and I were on the freeway. Without warning the vehicle shut down and we were forced to pull onto the shoulder. We sat there for almost an hour in temperatures of 13 degrees trying to get the vehicle restarted. There have been countless complaints and reports of other Envoy owners experiencing these same problems. Some dealers have actually said that these failures/problems are normal!!!! what!?!?! are you freaking kidding me?! since when is it considered "normal" when so many Envoys are displaying these same problems?.

: the contact stated while driving at various speed the headlights illuminate intermittently. Upon inspection the dealership was unable to duplicate the cause.

: the contact stated while driving uphill at no particular speed, the engine stalls and operates at a reduced speed. Additionally, the headlights intermittently work at night and the gas gauge provides an incorrect display of the proper fuel level. Although the vehicle was seen by a dealer numerous times, the dealer was unable to duplicate the problem. The consumer stated the electrical system is faulty. The left front window dropped the lights became dim and the battery failed. Updated 04/06/06.

I own a 2005 Envoy - 7 months after owning it - while driving in the dark all the sudden the headlights and dash/radio/mirror lights started flashing on and off. "like a cop car" to the point we pressed on star-afraid the car was going to stall on busy/dark freeway. When I called a dealer they said OH "that's normal" you had to much running and new cars can not handle "heater/radio etc. "its no big deal" > I called another dealer and they said no-this is a problem bring the car in. Ends up there was a bulletin for this and the chip had to be updated. Very wrong for the one dealer to say no big deal-when they know a update was out.
