“Nov.2013 was the frist time we had a proplem, right after that the oil gauge was not working. On an off we have noticed other type of problem that seem to be electrical. For the last year \year an half my gas is all over the place, always stopping to get gas as not to give out. Also, my gear and mileage gauge does not work. Now have no idea when to change the oil or rotate tires”
NHTSA complaint #11001457, filed 2017-06, 75,000 miles“Since june 2010, the fuel level gauge on my 2005 Chevrolet Trailblazer has not functioned properly. Regardless of the actual fuel level, it reads at 1/4 tank or below, which causes me to rely on my trip odometer to estimate my current fuel levels. I have checked with the Chevrolet dealerships, and they are charging between $500 - $800 to correct this problem! …”
NHTSA complaint #10377789, filed 2011-01, 42,627 miles“Since the purchase my tb engine will stop when AC and heater is on on stop light, that it was delaying while driving. It got worse after warranty was out, I believe in july 2007.no one can find the cause, but thinking its all system faulty., engine, electronics, fans. Could I afford a new car, I would not keep this car, as now I know it was the worse year making of all. Now I only pray to stay alive while driving and not get into some beyond my control but faulty GM model makers”
NHTSA complaint #11062893, filed 2018-01, 70,000 miles“My RPM gauges started messing up need my speedometer started next. They started sticking and jumping up. My 2005 Trailblazer only has 47,000 miles on it and the check engine light stays on all the time. Has been serviced regularly so I really don't know what it going on with it!”
NHTSA complaint #10377753, filed 2011-01, 45,000 miles“I noticed my battery guage quit. Then after starting my truck a few different times, the gas guage read differently. Then my speedometer wduld stick on 100 when I was doing approximatly 60. Then the speedometer would not work at all. There needs to be a recall on it. My friend has a 2005 also and her cluster pannel went out too. Its a 400.00 repair. This has happened to quite a few 2005 Chevrolet trailblazers from what ive read online. Come on general motors. You need to recall these models.”
