Recalls
2 recalls name the 2004 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.

As you come to a complete stop or go under 5 mph, the vehicle's oil gauge will go all the way down. Once you accelerate, the oil gauge goes back to normal. When pumping gas into the vehicle, the gas pump will reset as if the gas tank IS full but the gauge shows it's half empty. *tr
- Electrical system
Most of the gauges are very erratic when in motion or stopped. tachometer jumps around, oil pressure reads all over, speedometer goes to zero or full scale, amp meter drops below 14 and lights dim when this happens, (have had the alternator replaced 3 times, this IS quite a safety concern for me as I have no idea what to believe on any of the gauges. no repair shop has been able to solve the problem.

1 owner vehicle - bought in 2004 & had 8 miles on it. Has been very well kept & currently has only 65,000 miles on it as of 9/16/19. As others, the electrical cluster has malfunctioned. Speedometer quit working over a year ago & now the fuel gauge has failed. Problem IS with the cluster as "estimated mileage" still works. Have noticed that other gauges act erratic at times. This has been an ongoing issue that chevy IS well aware of yet fail to act. To tb to dealer for repairs they stated there IS no recall. Cost out of my pocket for repair will be over $800.00. Speedometer originally failed while driving on hwy. It started to work again but failed again while driving on the hwy a few weeks later. Fuel guage simply stopped working after starting vehicle.

When driving our vehicle from myrtle beach this week we noticed a smell about half way home that reeked of rotten eggs. The smell was so bad that I because nauseous and develooed a severe headache. After we reached our house and shut off the vehicle the next day I tried to crank the vehicle and it would not crank so after researching the smell and possible causes we bought a new battery for the vehicle and changed the battery ourselves which caused my husband to develop a severe cough and upper respitory problems due to the boiling that was occuring inside the battery. Hence the smell of rotten eggs.

I own a 2004 chevrolet trailblazer ext and just like the thousands of others mine has a defective gas tank filler on the top of the tank. It's a known bad part feom the factory. Mine has had a hole for a while now. It can literally leak over 10 gallons of gas a day if you fill the tank to full. Even if you don't the smell of gas in and around the vehicle IS terrible. My check engine light IS on because of it. It runs like crap because of it. What's more dangerous than spilling gas everywhere you go!? Some people have had chevy pay for the repairs on there 2004 trailblazer. Look it shouldn't matter what your vin# IS or how many miles at this point (i just hit 150,000) the gas tanks on these vehicles are faulty, they're dangerous, they're exspensive. I surely dont have $800-$1500 laying around to fix a part that IS known and proven to be bad. We all know tbey are bad, chevrolet knows it, the nhtsa knows it. The kicker IS you cant even find used gas tanks for these things to save money. Every single one IS junk or already replaced one that was junk. It IS completely crazy that the owners of these vehicles where never probably taken care of in regards to this issue with the gas tanks

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.
