Five problems related to other fuel system pump have been reported for the 2007 Chevrolet Trailblazer. The most recently reported issues are listed below.
Shortly after christmas 2015, while driving on a city street the red light on the gas guage came on and the gauge showed empty. Having just filled the tank earlier that day I thought the gas had been stolen. I pulled into a station to refill but it was still full. For the next five weeks the check engine light was on and the gauge only worked occasionally. It wasn't a dangerous situation but after a few weeks of guessing how much gas was in it, I took it to a repairman who replaced the fuel pump module assembly for a mere $767. 04. The odometer is only at 47,760.
Inaccurate fuel level reading. In November, my fuel gauge and driver information center began to spontaneously read erratically and would not accurately show me how much gas I had. Condition has rapidly progressed to where the fuel gauge almost constantly reads empty, low fuel light is illuminated and fuel level low is displayed in the dic. In researching this issue, I found service bulletin no. 10054b which states it is a premature wearing of the fuel sensor and I should have received a mailed notice from gm regarding this known issue. I have not received any such notice. There are no recalls associated with my VIN and my warranty has now expired so there will not be "vehicle eligibility" for the dealer to confirm through the "applicable warranties section in the global warranty management system. " this issue is bigger than publicly acknowledged by gm and needs to be a full recall, not a 50/50 shared responsibility with the customer when gm acknowledges the issue is due to a faulty part that prematurely wears and causes the malfunction. Also, the entire fuel pump including the sending unit and fuel level sensor needs to be replaced, not just the fuel level sensor.
While picking my children up from school on 11/15/2012 I smelled burning plastic, then I looked down at the drive door it was smoking really bad. I put the car and park and opened the door, a police offcer was near as I was in the school zone he saw the smoke coming from my car and ask me was I okay. He turned the car off unsure if a fire was started on the inside of the door. After about an hour the smoke stopped, but my main power window and door was not working anymore. My car smelled like burning plastic for months. I was advised that the motor may have burned out and it would cost $550. 00 to have repaired. I noticed on 01/26/2013 my gas gauge was not working. I stopped at a local gas station and filled my car up with $62. 00 worth the gas and when I turned the car on it showed my car was on empty and the gauge light remained lit along with my engine light. So I turned the car back off and waited about 30 sec and turned it back on it stayed the same. I took it to the shop and was advised the fuel sensor was bad and I would need to have a new fuel pump put in. I bought my car on 02/27/2010 pre-owned with 76,000 miles on it, and was given a car fax report, and it was clean. I read all these reviews about the 2007 Trailblazers and it seems they all have the same issues. These issues need to be corrected as they have to be a manufactor defect.
The contact owns a 2007 Chevrolet Trailblazer. The contact stated that while driving approximately 55 mph, the engine stalled without warning. The contact noticed that the fuel gauge displayed and inaccurate reading of one quarter full when the fuel tank was actually empty. The contact called roadside assistance and was assisted by having fuel dispense ned into the tank and the vehicle resumed normally. An independent mechanic inspected the vehicle and advised that the fuel pump would need to be replaced. The vehicle was not repaired. The manufacturer was not notified of the defect. The approximate failure mileage was 75,000.
The ignition will not turn off unless the bright lights are on. At times, it will start automatically even when the ignition switch is turned off. Sometimes the ignition will not turn on or off at all. Fuel system is faulty. Consistently problems have caused the fuel pump to go out repeatedly, and the fuel gauge to stop working. Motor in the drivers seat stopped working after months of problems. The radio has stopped working. We've replaced the fuse, and have been told its an electrical problem.
