Gradual coolant loss over time and no evidence of leak. This was due to a crack in the cylinder head that gm admitted to knowing about in tsb 06-06-01-019b on june 12, 2007). Coolant was slowly leaking into the oil, but was unnoticeable until it started to affect oil pressure from the oil becoming slushy and ruining the engine. This ended up resulting in resulted in the low engine oil light suddenly coming on and the car to stop running on a highway. The engine started steaming and the car was overheating. Mechanic is now saying the engine is in an unoperable shape due to driving with continued low oil pressure (no light had appeared until day of incident). Gm had sent out a bulletin admitting to the issue but did nothing to notify their customers. They should immediately recall the affected vehicles and/or pay for a replacement. I had just put in a new transmission to my gmc envoy, expecting it to last for years.

What owners say
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.
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.
On december 20, 2015 we were traveling after dark (7:30 pm) and the head lamps went off. We managed to pull out of traffic safely. Could not figure out what happened. After sitting for approximately 5 minutes the lamps came back on and we were driving to our home and the lamps went off again. I took the vehicle to a chevy dealer and they could not help me. I then called the gmc dealer and got the same response. I then checked online and found out that gm knows of this problem which is caused by a headlamp module overheating. I know this problem is occurring to other people so why hasn't there been a recall.? Help.
Low beam relay (headlamp driver module (hdm) burned out--same thing happened 4-9-2015. This time melted the fan relay and fused the two relays together. 2006 & 2007 envoys were recalled for the same identical problem. The hdm overheated and caused headlamp and daytime running lights to fail and not illuminate. Gmc plans to charge approximately $800 for entire new set up because box is not sold without all relays. Was told possible further expense if electrical problems are found.
The AC blower resister overheated and melted. This is the second time in 3 years this has happen. The fan control usually goes out on all speeds followed by a strong smell of electrical wire burning. A online forum at trailvoy. Com has numerous threads of people complaining about this sane issue on their vehicle. One thread has 71 pages and is still growing (http://forums.trailvoy.com/showthread.php?t=32751). This is a fire hazard!
Tl* the contact owns a 2005 gmc envoy. The contact stated that while driving approximately 30 MPH, the dashboard became hot, the air conditioner failed, and the ABS and brake warning lights illuminated. The vehicle was taken to the dealer. The technician diagnosed that the ignition switch was faulty and caused the vehicle to overheat. The vehicle was repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 86,000.
Fuel light came on, speedometer stopped working, engine cut off. Before that, the muffler started making rumbling noise. I had just fueled the vehicle. Findings by aaa: ABS bad had to be replaced 1056$ and realignment. 2. Exhaust manifold and pipe replacement 400. Don't know about fuel system yet brakes /ABS is 3rd time since buying the car in 2006. 2nd time for engine issues. Car started overheating on beltway this week and blower motor not working right. Also have issues with window passenger side front wont work now and rear wiper stopped working. Holy you know! Think I got a lemon!
After six months having purchased this used vehicle from a local dealer, I noticed that the driver's door was not working properly, nor were the power window devices, controls, power locks and also the visibility of driver's rear window. I noticed that the door would overheat and sometimes I can smell an odor similar to when something is burning. I have taken the vehicle to a mechanic and finding the solution to the problem has been difficult. On june 2013, I read on the msn website that the gmc envoys for 2006 and 2007 were being recalled (recall #13v248000) in regards to driver's master power window switch. Since I am having this same problem, with my 2003 envoy, I called gmc and explained to her that I am having that same issue with my 2003 envoy. She indicated that gmc would pay for the diagnostic fee labor even though my car's mileage was not under warranty and that the recall was only for 2006 & 2007 envoys. She connected me to [xxx] for an appt. With balise the following day. She assigned a case number 71-1219059371. The following day, august 28, 2013, I went to my appointment at 11 am. And left my car. About an hour later, I get a call from gmc indicating to me that she was sorry, but that gmc could not cover the cost of diagnostic fee labor. I said, "that is not what you told me yesterday" and she replied, "I am sorry, I was not authorized to tell you that". I said to her, "I wouldn't have taken time off from work, ask for a ride, be without transportation if you had told me that before". I also said to her, "how can you tell me you are covering the cost yesterday and today change your mind". All she responded was, "I am sorry". I asked to speak to her supervisor by the name of [xxx] and the supervisor just said that her employee was not authorized to say to me that gmc would cover the cost. I still have the same safety issue.

Engine and engine cooling
- What is wrong
- Some sport utility vehicles equipped with an electronically controlled air suspension (ecas) have a condition in which the ecas may produce a brief electrical spike while the vehicle is operating. This electrical spike can disrupt the powertrain control module (PCM) causing the vehicle to stall.
- Risk
- If the spike damages the PCM, the vehicle may not restart. If this happens while the vehicle is moving, a crash could occur without prior warning.
- Remedy
- Dealers will install a wiring harness. The recall will begin on august 19, 2004. Owners should contact oldsmobile at 1‑800‑630‑6537 or gmc at 1‑866‑996‑9463.
