Recalls
3 recalls name the 2003 Chevrolet Trailblazer Ext. Newest first.
Certain sport utility vehicles have a rear side closure latch that may not latch or unlatch due to corrosion caused by road splash, such as water and road salt. these vehicles were originally sold in or currently registered in the following states: connecticut, delaware, illinois, indiana, iowa, maine, maryland, massachusetts, michigan, minnesota…
Risk and remedy
Risk
If the door IS not latched properly and it goes unnoticed, it may open while the vehicle IS in motion. if an unbelted occupant fell out of the vehicle, personal injuries could occur.
Remedy
Dealers will install a seal along the lower part of the rocker panel to prevent intrusion of corrosive material, and inspect the rear side closure latches. functional latches will be cleaned and lubricated. non-functioning latches will be replaced. the recall began on february 24, 2006. owners may contact chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, or isuzu at 1-800-255-6727.
On certain sport utility vehicles, vibration and heat may cause the tail lamp/stop lamp bulb to loosen in its socket. if this occurs, the bulb may flicker and eventually become inoperative.
Risk and remedy
Risk
An inoperative brake lamp will not convey the driver's intention of stopping to drivers in following vehicles, and an inoperative rear turn signal lamp will not convey the driver's intention to turn to drivers in following vehicles. both of these failures can increase the risk of a crash.
Remedy
Dealers will inspect the tail lamp/stop lamp assemblies, and if necessary, replace them. the recall began on november 22, 2004. owners should contact chevrolet at 1-800-630-2438, oldsmobile at 1-800-630-6537, buick at 1-866-608-8080, or GMC at 1-866-996-9463.
Certain sport utility vehicles have windshield wiper systems that will not turn on, cease operation while in use, fail to turn off/on by themselves (moisture sensitive wiper system), or have continuous windshield washer pump operation because the presence of water within the wiper modules can either cause a short circuit or can lead to the corrosion of…
Risk and remedy
Risk
Depending on the occurrence and weather situation, driver visibility could be reduced, which could result in a crash.
Remedy
Dealers will cover the windshield wiper module vent hole with a patch. also, the wiper motor, circuit board, and electrical connector will be inspected to signs of water intrusion and/or corrosion and be replaced as required. the recall began july 6, 2004. owners should contact chevrolet at 1-800-630-2438; oldsmobile at 1-800-630-6537; or GMC at 1-866-996-9463.

The ABS light has come on and then it would work sometimes and not other times. Now it never works. Now that its winter I'm sliding at stop signs that aren't even that slippery. the actuators in the heating and cooling are not working properly. all summer I had heat blowing all the time and suddenly there would be nothing. Now it's cold air all the time. Makes my windows fog up and not defrost. I have done the reset procedure and hear things moving but it doesn't fix it. the blower in the ball seat and third row IS hit or miss for even working at all.

One by one things have been going out and not working. First the car would not start all the time with the key, then the a/c stoped working, next was the fuel pump, then the injectors. I checked everything it could be. I was driving with my kids down the highway when my car just died lost power steering so it was hard to get off the road fast. I got it started and was driving and it did it again. I was able to finally get it home when it would not start again. After some research online found out this car has issues with the fuse box itself under the hood. I opened it up just to find the wording that connected the pins was broken in numerous places and had started to burn up in the box.

None of my gages work and a lot of my dash lights are on. I have no idea how much gas I have. My speedometer and rpm gages work but nothing else does. This has been happening on and off for about 3 months but they would always go back on. But now it has been off for a week without going back to normal. Twice last week the radio and the power windows stopped working as well. this happens while driving parked all the time and it doesnt go back to normal. I have seen a lot of complaints about this so I have no clue why there isn't a recall. It IS not safe to drive my trailblazer until these things are fixed. I work at a chevrolet dealership and they couldn't figure out how to fix this either. Gm needs to put out a recall to get this fixed asap.

The gas gauge started messing up/not reading right especially in the rain and then shortly after that the speedometer started doing the same thing. Now neither one will work at all. This started about two years ago and quit working all together about 1 year ago. I heard that this IS happening to alot of trailblazers. This started while the vehicle was in motion.

My wife and five children traveling on I-94 e and exited the freeway at the 12 mile exit in roseville mi. my wife attempted to brake as they approached the red traffic signal on the 12 mile exit ramp and the brake pedal went all the way to the floor without warning. she was unable to stop the vehicle and proceeded through the red light narrowly missing a high speed collision with both east and west bound traffic on 12-mile road. she continued through the intersection on the red light and was able to stop the SUV several hundred yards down the service drive. She slowly drove the vehicle home and I checked the brakes and the pedal went straight to the floor with no brake warning or any other indicators on the dash. I pumped the brakes several times and couldn't even hold the vehicle while idling in the drive position. I also noticed a large puddle of fluid under the driver's side of the vehicle. I'm going to limp the vehicle to moran chevrolet in clinton township, mi and leave it with those that sold me this deathtrap. another and perhaps even greater safety concern I have IS the suv's tendency to misbehave while in AWD mode. the vehicle sometimes goes in reverse while drive IS selected and vice versa. additionally, the vehicle will sometimes put itself in neutral while engaged in drive mode or while stopped at traffic signals. oh and last week I replaced the windshield wiper assembly after it failed and found no evidence that gm had completed the related recall work that signed off as being complete for the windshield motor and linkage assembly. I see I'm not alone in having suffered catastrophic safety related failures with this particular SUV. please take notice and force gm to recall to fix this corrosion issue with the brake system. I almost lost my family last evening and will assume it would have made national news had they died in an accident.

I purchased a 2003 trailblazer from an individual. The front differential had a hole in it. So I purchased a differential from a scrap yard. 90 day warranty. Still had a noise . I still had a noise front differential was out again. I purchased the third differential from a different yard took it apart . found the driver side bearing bad. It seems to be a very common problem because the driver side drivers constant. I was wondering if there IS a recall. I see a lot of complaints online. thank you there was a fire the differential grease burnt bearing went out and chard motor and surrounding area no real damage. *tr

Nhtsa action number : pe07014 occurred on my vehicle around november 2014. the problem presented as p0442 cel and odor of gas after parking in garage. gm has indicated because the special consideration allowance has expired, despite the low mileage they will do nothing. this vehicle was purchased new in august 2003. I do not understand why gm was not compelled to issue a safety recall due to the risk of gas leaking. I would appreciate assistance to get gm to minimally provide defective parts replacement, due to the know manufacturing defect in the gas tank. *tr

It was sleeting and I lost control on a curve. I had been driving about 50 mph, but brake before the curve and brake very hard when I tried to regain control of the vehicle, as it was sliding sideways toward the curve. I went off the curve and hit an elevated crossroad, which sent the vehicle airborne. I was airborne over most of the side road, with the rear of the vehicle hitting just the last few inches of pavement, which then sent the vehicle nosediving into the ditch. the embankments were 4-5 feet tall. I had two very hard front end impacts and hit my head on the steering wheel twice. the frame of the vehicle was bent and there was a lot of damage to the under of the vehicle, but the airbags did not deploy. the vehicle has been deemed a total loss by my insurance company. I have a lot of concern with the fact that the airbags did not deploy and know that there were other vehicles of my year and type that did have faulty airbags recalled, but mine has not been. *tr

Plastic weld connecting fuel fill pipe to fuel tank has cracked.contacted gm about this issue & was informed that this vehicle had just missed the campaign to fix this problem by one month. Why IS this campaign (07099) a limited tsb & not a safety recall? Vehicle would not pass state emissions inspection. Technician repaired leak with epoxy that sealed long enough to prevent vapor leakage to pass emission test.now that has failed and once again vehicle will not pass emissions. More importantly the fuel vapors emitting from vehicle make it unsafe and impossible to park in an enclosed area.this IS not due to a worn part or corrosion,this IS due to a faulty design that eventually will cause an explosion.worse yet gm offers no discount on this very expensive tank assembly to correct this problem.i can not think of a more dangerous condition that has been so ignored.perhaps when the fires start there will be another congressional hearing about gm's ability to respond to such a serious and possibly loss of life hazard that they refuse to assist owners in correcting. *tr

I found that one of the wires had overheated and actually burned the foam and covering. There are many complaints and pictures on the internet. I removed my seat and found the exact same problem. I am astounded that nothing IS being done to stop the use of these defective heaters. This IS most certainly a very serious fire and burn hazard. *tr

My vehicle started randomly shutting off while driving. Loss of power to everything but the brakes. Luckily I was only going 10-15mph each time this happened. With the recent recall in gm vehicles regarding the ignition switch I thought it would be a good idea to switch this part out first. Fixed the problem immediately. I would like to be reimbursed my cost for part and labor. I can't believe as many known problems the trailblazer has with this that it has yet to be added to the recall list. *js

When I pulled into driveway, I put the vehicle in park, and turned the key off, and actually pulled the key out of the ignition switch, with the vehicle still running. I backed the car up, without the key in the ignition, where I started smelling wires burning. I called fire department, and they put fire out on the fuse box, with everything melted around it. I have had minor problems with the car, i.e. Wheel bearing and brakes, but, nothing like this.

There IS a strong odor of gasoline vapors coming from the rear of the vehicle, a crack can be seen in the neck of the fuel tank. When filling the vehicle, fuel spills out of the tank from the crack. The fuel gauge cluster in the dash doesn't work. The blower on the a/c unit doesn't work on the highest (5) level. Also, the fan clutch went out causing the car to overheat severely. The fan does not engage, causing the water pump shaft to become damaged. Also, the rear driver side window quit functioning, despite buying an expensive new regulator and replacing it. Having researched the issues, I find that I am among hundreds, possibly thousands of unsatisfied people with the same problems. *tr

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 NHTSA 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 NHTSA.gov under the identification numbers in the attached document.

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 nhtsa 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.
