Recalls
8 recalls name the 2003 Chevrolet Trailblazer. Newest first.
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 and remedy
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.
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.
Certain minivans, passenger and sport utility vehicles fail to comply with the requirements of federal motor vehicle safety standard no. 225, "child restraint anchorage system." the owner's manual does not explain the meaning of the location symbols for the child restraint lower universal anchorage system.
Risk and remedy
Risk
This does not meet the requirements of the standard.
Remedy
Owners will be provided with a supplement for their owner's manual. this supplement describes and shows the location symbols for the child restraint anchors that are located in the vehicle and on the child restraint or booster cushion. owner notification began august 18, 2003. owners should contact buick at 1-866-608-8080, cadillac at 1-866-982-2339, chevrolet at 1-800-630-2438, GMC at 1-866-996-9463, pontiac at 1-800-620-7668, or oldsmobile at 1-800-630-6537.
Certain sport utility vehicles were built with a left-front brake pipe with a circumferential score at a random location along the length of the pipe as the result of the manufacturing process. if the brake pipe partially or fully fractured, brake pedal travel would immediately increase and front brake performance would be reduced.
Risk and remedy
Risk
If braking performance IS reduced, a crash could occur.
Remedy
Dealers will replace the left-front brake pipe. owner notification began on may 29, 2003. owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1-800-222-1020, GMC at 1-800-462-8782, or oldsmobile at 1-800-442-8006.
Certain sport utility vehicles fail to comply with the requirements of federal motor vehicle safety standard no. 114, "theft protection." these vehicles are equipped with a mechanical override that could allow the ignition key to be removed with the shift lever in a position other than park. in addition, these vehicles have an override that can allow the…
Risk and remedy
Risk
These overrides are not permitted unless the vehicle has a locking steering column.
Remedy
Dealers will eliminate these conditions by disabling the overrides. owner notification began on may 29, 2003. owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1-800-222-1020, GMC at 1-800-462-8782, oldsmobile at 1-800-442-6537, or hummer at 1-866-486-6376.
On certain MINI vans, passenger and sport utility vehicles, some of these vehicles have a driver's side air bag that may not deploy as designed. in addition, the air bag inflator could rupture.
Risk and remedy
Risk
This could result in reduced capability of the air bag to protect the driver. also if the air bag inflator ruptured, pieces of the inflator could strike and injure the vehicle occupants.
Remedy
Dealers will inspect, and if necessary, install a new driver's air bag. owner notification began on march 11, 2003. owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact buick at 1-800-521-7300, cadillac at 1-800-458-8006, chevrolet at 1-800-222-1020, GMC at 1-800-462-8782, or pontiac at 1-800-762-2737.
Certain passenger, MINI vans, and sport utility vehicles have an air bag inflator on the driver's side that could fracture at a weld during a deployment.
Risk and remedy

While driving my Trailblazer in A4WD on slippery road conditions, I went to pulled out of a parking lot and there was a loud sound like my whole front end fell out and the front end completely locked up. Almost causing an accident. I had to dial back to 2HI quickly to unlock to front end. There was no light indicating any problems. Been driving it 2HI since with out any problems. Still no service light or anything, but feels like I'm stuck in A4WD. Feels like there is a drag and a pulling to the right. Also using more gas since. It was a scary, afraid to try the 4x4 functions again. Another snow storm is on the way!

In 2018 we were having a fuel pressure issue and discovered that the icv had cracked around the gas tank. when I researched the issue I found there was a special coverage warranty for the issue and called the nearest chevy dealership. They told me that the coverage had expired a month earlier and they wouldn't honor the coverage but if we wanted the car fixed it would be over$1000. We're not the first owner of the vehicle and im sure that's why I never received the notice of the special coverage. considering this IS an issue with the fuel tank and I have children in my car, I'm not understanding why this special coverage expired in the first place. people buy used cars all the time and if the dealership didn't catch it before selling the car it's unfair to put the expense on the new owner when it's a defect caused by the manufacturer's choice in unreliable parts. *tr

For the last 3 years, every part of my instrument panel seems to work intermittently. at times while driving, the speedometer will show me doing 40 mph over my actual speed, or will show me doing 120 while I am sitting still. the oil pressure will sometimes show that there IS no pressure at all, or the temp IS as far as it can go on the hot side. all of these issues disappear after a while, and then function normally. they do not seem to be tied together, because at times several instruments are working fine, but 2 others are not.

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.
- Fuel pump module leaks gasoline
Odi has received reports that the fuel pump module leaks fuel and or vapor underneath the vehicle.gm states, the failure mechanism IS corrosion of the fuel pump module flange which may lead to a fuel leak.corrosion of the fuel pump module flange IS the result of the vehicle operating in a corrosive environment.odi has upgraded this pe to engineering analysis (ea07-009) to further assess this issue.

The subject vehicles (chevrolet trailblazer (ext), GMC envoy (XL), and oldsmobile bravada) are built on the gmt360 and gmt370 platforms and were originally equipped with a windshield wiper assembly referred to as the ?family? Design module (p/n 15171306 base, p/n 15171307 for vehicles equipped with rainsense automatic moisture sensitive wipers).the windshield wiper assembly IS located inside the plenum at the base of the windshield and IS mounted on an incline approximately equal to the rake of the windshield.gm reports that vehicles are subject to a quality assurance water test at the assembly plant.the test exposes the vehicles to an amount of water that exceeds the plenum?s capability to divert water away from the wiper module, allowing water to rise to a level that exceeds the height of the windshield wiper motor cover vent hole.water enters through the vent hole then flows down to the bottom of the module and pools causing the electrical components on the control circuit board to corrode and short out, thus rendering the wiper motor/module inoperative.on november 2, 2002 gm introduced into vehicle production a redesigned windshield wiper assembly referred to as the ?global? Design module (p/n 15094704 base, p/n 15094705 for vehicles equipped with rainsense) that uses a polytetrafluoroethylene membrane covered vent hole to control water intrusion.there are a total of 1,172 non-duplicative owner and field reports alleging windshield wiper failure, two vehicle crashes allegedly caused by windshield wiper failure, and 43,219 warranty claims for windshield wiper assembly or wiper control module replacement on vehicles originally equipped with the ?family? Design module.this preliminary evaluation has been upgraded to an engineering analysis (ea04-002) to further study the scope and safety consequences of this issue.
