Recalls 1
Exterior lighting: turn signal
- What is wrong
- On certain trucks and sport utility vehicles, the driver wishing to signal a turn by moving the directional signal lever, (up or down) may cause the front marker/turn lights and rear turn lights to flash in a manner similar to hazard warning, rather than flashing on the desired side only.
- Risk
- The driver may not be able to clearly signal their intentions to turn, change travel lanes, or potentially warn others of an impaired vehicle operating condition increasing the risk of a crash.
- Remedy
- Dealers will replace the suspect flasher modules with a new flasher module designed with sealed relays and more durable contact material inside of the relays free of charge. The recall began on august 4, 2005. Isuzu began mailing owner letters on august 4, 2005. Owners may contact chevrolet at 1‑800‑630‑2438, gmc at 1‑866‑996‑9463, isuzu at 1‑800‑255‑6727, buick at 1‑866‑608‑8080, and oldsmobile at 1‑800‑630‑6537.

Defect investigations
Loss of Headlights
The subject vehicles are model year (MY) 2002-2009 Chevrolet Trailblazer, GMC Envoy, 2004-2007 Buick Rainier, 2003-2008 Isuzu Ascender, 2005-2009 Saab 9-7X, 2002-2004 Oldsmobile Bravada, 2003-2006 Chevrolet SSR, 2005-2009 Buick Lacrosse, and 2006-2008 Pontiac Grand Prix. This scope includes the Trailblazer/Envoy variants: 2002-2006 Envoy XL/Trailblazer EXT and 2004-2005 Envoy XUV. The original scope of this investigation was expanded to include all vehicles equipped with the subject Headlight Driver Module (HDM). The focus of the investigation was to determine whether actions performed by General Motors adequately addressed any unreasonable risk to motor vehicle safety in the subject vehicles concerning the headlights and the HDM that controls them.Under normal electrical load and environmental conditions, the HDM can overheat inside the Underhood Electrical Center (UEC). This can cause the module to fail and result in a simultaneous loss of both low beam headlights and both daytime running lights (DRLs), often with no warning or prior detectability to the driver. This failure can be intermittent or permanent. No other exterior lights are affected. High beams, turn signals, brake lights, and reverse lights are still operational.General Motors addressed this issue with 2 recalls (14V755 & 15V519) and a special coverage program (N172091910). In view of the recalls and special coverage program implemented by GM and the vehicle high beams continuing to operate, ODI has tentatively concluded that the actions taken by GM mitigate any unreasonable risk to safety posed by HDM failure in the subject vehicles.Accordingly, the investigation is closed. The closing of this investigation does not constitute a finding by the federal safety agency that a safety-related defect does not exist. The agency reserves the right to take additional action if warranted by new circumstances.The ODI reports cited above are available for review online at under the identification numbers in the attached document.
RQ17002
Fuel pump module leaks gasoline
During the course of this ea investigation, odi observed that the majority of the complaints (88%) and warranty claims (94%) were reported for vehicles that are registered for use in the salt belt region of the us.this area includes 20 states in the northeast, mid atlantic and the midwest regions and the district of columbia.consumers in the salt belt region reported to odi that they could smell fuel vapors in their vehicles while driving.upon further examination of their vehicles, they discovered that fuel vapors were coming out of the top of the fuel tank. This condition is caused by corrosion of the return and sender lines of the fuel pump module.water and road salt collect on top of the fuel pump leading to small pinholes appearing on the fuel lines.fuel may leak and collect on top of the module and/or spill onto the ground.the data evaluated under this investigation reflect a relatively low frequency of occurrence that largely arises in salt belt states.gm has extended the warranty on the subject component to ten years or 120,000 miles.further use of agency resources does not appear to be warranted at this time; accordingly, this investigation is closed.the closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists.the agency reserves the right to take further action if warranted by the circumstances.for additional information select document search.

PE05006
Brake lamp failure
Gm states that some brake/tail lamp bulbs can prematurely become inoperative due to malfunctioning brake/tail lamp sockets.on march 2, 2004, gm initiated a 6-year/72,000 mile special policy for 989,487 subject vehicles to inspect and replace the rear brake/tail lamp bulb socket assemblies.on april 4, 2004, the office of defects investigation (odi) opened a preliminary evaluation (pe04-032) based on consumer complaints alleging brake lights not operating when the brake pedal is depressed.on august 3, 2004 odi upgraded pe04-032 to an engineering analysis (ea04-021).by letter dated october 27, 2004 gm notified the federal safety agency that it will conduct a safety recall (the federal safety agency # 04v527) covering subject vehicles that were not already repaired under gm's special policy.my 2004 subject vehicles built after august 8, 2003 contain improved brake lamp assemblies and are not included in the recall.gm dealers will install the improved brake lamp assembly on subject vehicles built on august 8, 2003 and earlier.the action taken by gm is sufficient to resolve the issues raised by this investigation.accordingly, this investigation is closed.

Headlight's,taillight's,turn signals stop working whenever they want.It's pretty scary to lose your headlight's when your driving at night.There's nothing i can do about it,except to sit wherever it happend and wait for them to come back on.My wife was following me one day and told me my brakelight's and turn signal stopped working and started to work again,she said this happened a couple time's at the same red light.There a couple of thing's (electrical)inside the vehicle that don't work anymore but i really dont care about them.To get the odometer to work i have to knock pretty hard on the plastic cover that cover's the instrument cluster,sometimes it stay's on,most of the time it wont stay on.The DIC (driver control center) doesn't work anymore.I cant even get to it.The speakers on the left side of the vehicle dont work anymore.I thought i would tell you about the inside also because it could be part of the problem.All of this happened when i was driving home from my daughter's two night's ago.I bought this vehicle about three or four's year's ago,and i had no problem's with it untill the other night.The person i bought it from is a good friend of mine.He said he never had a problem with it,plus i have been in this vehicle countless times,that's why i bought it. Thank you.

I was driving in the city at night time and my low beam lights quit working. I did not notice it right away because of the street lights. This could have caused an accident and put my husband, daughter and myself at risk.
Rear air compressor bags are faulty....from what I understand this is happening to many gmc envoys and need to be recalled!!!
I just had my brakes serviced and my bushings changed, but my ABS light still comes on. Also when I go to brake the car starts to shake and I'm going the speed limit. The engine has a rough idle, and shuts off when at a complete stop and when the vehicle is in motion. I've had many things replaced on the vehicle, such as purge valve, gas cap. Charcoal canister and fuel tank. In the engine the spark plugs were changed as well as the coil packs and the fuel injectors. Along with the camshaft sensor. Still getting p0455 and po0014. Won't pass smog can't register vehicle, but my only means of transportation. 2004 gmc envoy xuv slt 4dr 2wd
