What 2006 Chevrolet Blazer owners say
Fuel & propulsion system
Was parked at job site after having filled fuel tank. Low fuel alarm and light came on. When started vehicle gas gauge registered empty. After several off/on sequences for the ignition, fuel gauge would only register empty. Had repaired same day from dealer. Was told this was a warranty issue, and our deductible was 50% ($175). I told dealer I would contact GM to get the "deductible" refunded. I will let you know how that goes. Three weeks ago the vehicle lost the #6 fuel injector and it took out the fuel injector control module (computer system??). Total cost from dealer was $1633.01. Contacted GM, was refunded $592. This a municipally owned vehicle, probably why we received refund.
I recently noticed my 2006 trailblazer's gas gauge rapidly going to empty. A couple of days after my warranty ended this problem occurred. Now when ever I start my car the gage will show the correct amount but rapidly go to empty. Before taking it to the dealer I decided to look on the internet to see if I could fix the problem on my own. While researching I came across the following website with over 100 complaints about this same problem:www.aboutautomobile.com. Every complaint and the same problem and many did take their vehicle to get fix but the problem wasn't ever really fixed.
