| I have a 2007 chevrolet trailblazer ls. we bought it with 13 miles on it when the first full tank of gas was gone we only put on 235 miles to the tank. that wasn't even a week. we have had 2 tires replaced because of excess wear with only 6,000 miles on it. now we are working on the 2 other tires getting replaced because of the same thing. the windshield washer fluid would take a long time to come out. we hear a noise coming from the front right tire and at the same time we feel it in the pedals. the seals on the windows are coming off. there is no drivers side cover on the mirror on the sun shade. there is no door ajar ding or light that will come on when you open the door only just for the hatch. i have had my trailblazer in for service 3 times in 1 year for all the same things and everytime they say there is nothing wrong with it except for the tires. with the gas mileage my dealership said i have to wait 10,000 miles before i get a better average on the miles per gallon. well it is actually i am getting less and less miles per gallon than i did a year ago. the trailblazer is very slow at picking up speed. it hesitates at the start of pick up speed like the truck just stalled. i feel it in the pedal. the brakes have problems when it comes to stopping its like the brakes don't want to stop the truck. these problems are making me very upset. i have complained to 2 dealerships and both times they say oh there is nothing wrong with the truck. i need these problems fixed. so i will take any advice you can give on what i can do. *tr | |||
