2007 Chevrolet Trailblazer: fuel pump failure

Filed Oct 7, 2015 · Driver assistance, Electrical · TX

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.

Fuel gauge read full tank when in fact the tank was empty. I ran out of gas in my driveway. When this occurred my on dash computer went crazy lighting up then turning off, when I put gas in the car and restarted several times the computer seemed to correct itself. Filling the tank the gauge read empty and remained that way for several days. The gauge operates intermittently. I recently had the fuel pump replaced after failure. The pump was replaced prior to this incident. I have scheduled the gauge repair with my dealer.

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 officer 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 manufacture defect.

After filling the gas tank at a local wawa gas station that I've used since owning the vehicle, I began to head home after work. As I left the parking lot and proceeded to merge onto the main highway my fuel gauge and fuel pump completely stopped working, truck had shut off as if it had run completely out of gas, which was not the case as I had just filled the 22 gallon tank with approx. 20 gallons of fuel. Thankfully I was able to keep the fuel pump operating after letting the truck sit for about 15 minutes, but the fuel gauge is no longer operational, but who knows how long the fuel pump will operate properly. Unfortunately my fiance and child now have to drive this vehicle due to the fact of our second vehicle being sold. It has now become a safety issue as there is no bearing on fuel level in vehicle. I've done research and found this issue to be a recurring theme for the model years 2005 - 2007 as well as seeing special policy letters sent out by gm to acquaintances with the same model year SUV for a rebated repair from a licensed gm dealer and yet I've not received one. Its now affecting the registration process for my vehicle to comply with state regulations. I do not feel as though any responsibility should fall on the consumer for a part that was poorly fabricated by the manufacturer.

I had gone to a friends house and on the way home my power steering malfunctioned. I took the vehicle to a local auto repair shop and was told the power steering cooler had rusted through. I also had to replace this part on my 2003 trailblazer not realizing there was a problem. If this part rusts out on different years of the same model there seems to be a problem. The vehicle became very hard to steer. I know for a fact that I and many other people have had problems with transmission lines gasoline lines and power steering lines. I had to replace the gasoline line and fuel pump on the 2003 , and just replaced transmission line on the 2007. I think there needs to be an engineering change on these vehicles. I also received a recall notice on the 2007 trailblazer for the electric window switch. The notice said I would be notified when to bring my vehicle in. It has been several months since I received the notice and I am still waiting for notification. It cost me $350.00 to have the power steering repaired..

I will soon be replacing my 3rd fuel pump. You can not purchase a sending unit separately and you can not replace a fuel filter for maintenance. Also the master window switch stopped operating yesterday after a burning smell filled the truck. The master window switch is melted. Had issues with I first bought the truck with it "shutting down" on the highway, no gas, no power steering, no control. Received a year of free oil changes from chevy after a complaint was filed, they still to this day can not tell my why my truck would randomly shut down. *tr ....updated 06/18/12 *bf updated ivoq 06/20/12

My car quit reading out how much fuel I had. I had to write down on a piece of paper the miles on the car when I filled it up in order to keep track of when to put gas in again. With my husband being disabled this was not good. I took it to my dealership and they wanted closed to $100.00 just to tell what exactly was the problem then if it was what they thought it was it would be approximately another $600.00 to fix it. I took it to a reputable repair place it cost $0.00 to tell me the problem and it cost me $418.80 to fix it. The problem was the fuel sensor was not registering the amount of gas I had. They had to take the gas tank apart and replace that plus the fuel pump (as now these 2 items are built into 1).

I have a 2007 chevy trailblazer, for the last year I have been having problems with my SUV wanting to stall. I had my fuel pump/gauges replaced 1 year ago because my fuel gauge did not work at all. I was told that the fuel gauge is read by a portion of the actual fuel pump that is inside my fuel tank. That cost me more than $600 out of my own pocket since they had to remove my fuel tank to replace it. My fuel gauge has been working fairly normal up until yesterday, on my way to work at 6:15am my vehicle stalled in the driving lane of a 2 lane frontage road because I was out of gas. Thankfully, the road was not extremely busy at that time of morning. However, my fuel gauge still showed that I had almost 1/2 tank, when in fact my car stalled because I ran out of gas. I hope that some kind of resolution can be agreed upon with gm to get the problem corrected so that it does not happen in the future.

My 2007 gm trail blazer's fuel gauge began to show an empty tank when I would fill it up, and then when I would drive for a while, it would register full. Eventually the engine light started coming on and going off at random. I took the vehicle to a garage and was told it would cost approx. $800.00. I could not afford that, so I started inquiring about the fuel pump and fuel sending unit. Eventually I found a web site where I could purchase the sending unit for approx. Half the retail price. I ordered the sending unit, took the vehicle to a garage to have it repaired and have not had any other problems with either the gauge not registering properly or the engine light coming on. If this investigation becomes a recall, since I have already made the repairs, can I be reimbursed? I would appreciate your response when your decision is made. Thank you.
