Defect investigations

Fuel pump module leaks gasolineOpened July 10, 2007, closed August 28, 2008

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.

Shut off vehicle , got out of drivers side. Shut door and as I closed door all my locks on door locked down. My grandaughter was strapped into a car seat in the back seat and we were unable to open doors to get her out. We had to contact police and they were unable to get doors to unlock. The locks would not work the windows would not work , the car was completely locked down . After 30 minutes of trying to get into car we finally got my grandaughter to squeeze out of her car seat upon coaxing her we got her to get her car seat belt unlocked , she tried pushing the door lock buttons but nothing would work, we had her try to use window buttons but they would not work either , we tried having her manually unlock door but they would unlock but door would not unlock. Upon despair we had her take key out of ignition and I carefully had her push unlock button on key chain and finally they engaged and unlocked the doors and windows and we got her out. This could've been a real dangerous incident if she would of not been able to follow my directions thank god she was smart. Or if car would of been running I don't know what could've happened . This has happened numerous times while I was in passenger side while my husband went into bank and store. I became locked in the car . I think this needs to be investigated because I have read this happening to many trailblazers owners. This could be a very dangerous situation.

Communicated to gm help center 10/30/2014: my 2003 chevy trail blazer has a strong odor of gas in the rear. The vehicle has only 63,000 miles and has been well maintained. I "googled" the problem and found it to be a known issue. In part: the federal safety agency #: pe07014 "in june 2007, gm will expand its special policy to address fuel tank inlet check valve (icv) fractures." will you help me remedy this problem? Short story, they reviewed my description of the problem and ultimately declined any remedy. I can understand that the extended warranty has pasted, but my issue is I never received any notification as noted in the federal safety agency # pe07014. Had I received that notification I would certainly have followed up on the problem. This vehicle was purchased new and has very low miles for being a 2003. In view of the lack of notification, I think the vehicle should be covered as outlined as part of pe07014. Had I received notification and ignored it, then it would my problem, but I never received the original notification.

Power window control on the passenger door started on fire and melted some of the door panel and window control module and wiring harness. The vehicle has the heated seat buttons on the window control module. (p/n 15096223). The vehicle had been parked in front of the house (no keys in ignition) when the window started going up and down by itself and smoke started flowing out. Completely melted the front 4pin connecter and wiring harness I still have the melted part if needed for anything. I found it interesting that you have now opened up an investigation on 2006-2007 models on the drivers door. I had did a few internet searches looking for recalls or such. Did find a couple post where similar things had happened to others where others had stated having to do with water coming in the window and shorting the switch (if this helps) thanks
