I hope I am following all of the posting procedures.
Long story short, my Trailblazer (2006 with 46,000 miles) was suffering from the faulty fuel level sensor problem. I called GM (and the National Highway people) to lodge a complaint (I took it to a dealer, got a quote and then nearly passed out. I wasn't willing to pay $1000 to repair a fuel level sensor). A few months later, I was driving--with about 50 miles left in my tank, according to my calculations--and my car stopped in the middle of the road.
After a fruitless AAA experience (are you sure it isnt a fuse, the battery or you just ran out of gas?), I had it towed to a local repair shop. They said that they have seen a lot of the fuel level sensors go bad, and have seen an increasing problem with fuel pumps. Something about the sensor and pump being attached--one one goes bad, the other one is going to too. They replaced the sensor, pump and filter.
Again, totally dumbfounded as why this would happen to a car with 46,000 miles on it (I only buy Shell fuel and have used those fuel system cleaners in the past), I called GM again to voice my concern with my car stopping in the middle of the road.
After jumping through a few loops, they tell me that GM just (as in earlier this month) issued a special bulletin on the fuel sensor problem (bouncing back and forth for a while, then eventually reading "empty" all the time)--not a full recall. They will pay 50% of the cost to replace the fuel level sensor (including labor).
They wanted me to tow the car to a dealer--I quickly shut this idea down. I already had the dealer diagnose the problem, I wasn't going to pay for a tow (already used my AAA tow) and told them it would have been great if they notified me of the special bulletin when it was issued (because I specifically asked to be added to the list when I first called a few months ago). They transferred my call to an upperlevel person and he told me that I just have to take my paperwork to a GM dealer and they will process it for me.
I have yet to go get the paperwork processed (I only got my car back on Monday). I still want a full recall! I think it is absurd that they are essentially admitting that the parts fail prematurely, but they are only 50% at fault...
I'd recommend calling GM before you do anything--file a complaint with them and tell them that a 50% reimbursement doesn't cut it.
