I was driving on the highway going 65mph which is the legal speed limit. I got cut off by a driver and light tapped my brakes to slow the vehicle down. When I did so the vehicle then swerved to the left and started drifting sideways directly to a wall. I went head on with the wall. Then I bounced back across all lanes of traffic again still sideways and drifting hitting another wall. Which is where the vehicle ended at the stopping point of the accident. No airbags deployed in the accident. The driver behind me who witness the crash stated that the vehicle started to loose traction before I hit my brakes and me hitting my brakes caused the vehicle to them loose full control. I was in the process of buying this vehicle from Gresham Ford in Oregon. I was told the vehicle was 100% road safe and passed safety inspections. Which is false.

I have a 2002 chevy trailblazer with goodyear wrangler sr-a tires. these tires are the absolute worst tires I have ever owned in my 34 years of driving! in dry conditions they are tolerable but one can tell that they're not sticking well to the road. when it rained slightly it becomes near impossible to drive with these tires. the best way to describe it IS as if you are trying to drive on a slick roadway almost like driving on oil or similiar to driving a race car on slick tires to drift with.

Recently bought a car that I believe they are illegally passing the inspections on. They proclaimed that fixed a major part to keep the tires on my car tie rods and cv axel. Just short time after it looked like the part was never replaced just tightened up and shortly after we had all kinds of issues with the brakes and anything that keeps the car driveing safely the brakes went out on me so I called to see what they did and why they never fixed it the berry next day they repo the car as if they are trying to hide and cover up the scams they have on people my kids are in that car daily it should be never passed the inspection we have had to pay for most of that.

NHTSA’s Office of Defects Investigation opened these reviews into vehicles including this one.
- 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.

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…
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.
