Fuel gauge does not provide accurate reading. Check engine light indicates fuel level sensor. I do not know if there is fuel unless I reset the trip odometer and monitor.

After purchasing a tank of gas and driving from the service station, my display registered empty and the check engine light displayed. I reviewed the vehicle owner's manual and discovered there was a serious problem. I retained the letter regarding this "possible" situation that I received in 2012 or 2013 (not dated), and took it to the dealership where I normally have my car serviced. Since the vehicle exceeded the allowable mileage (120,000), I was told they would not honor the 50/50 payment and the cost associated would be 922.83 to repair. I telephoned general motors regarding the condition and advised that I feel they should be 100% responsible for the repair, since the condition was anticipated and not due to normal usage. Based on the description of the problem and continued safety issue, chevrolet should correct the problem at no cost to the owner. This remains a safety issue that is not routine or associated with other vehicles. The cost is excessive and I was informed that gm would not correct the problem or pay any portion of the associated cost; at the least, all parts should be covered to correct this anticipated problem. I was informed that gm would not pay any costs associated with the repair. Consumers are asked to buy american products and manufacturers do not make every effort to encourage continued purchases.

I was on my way to work at an ongoing traffic on the interstate and my 2007 trailblazer security and engine lights came on. It started to slow down and the engine completely shuts off. This is a known issue and happens multiple times before, I took it to the dealership service department they said they fixed it and I was charged almost $300 dollars unfortunately it did not fix. This is the worst vehicle I've ever had quality of the vehicle is suck. I will never buy chevrolet again!!!!

I filled the vehicle up to full with gasoline. The bell chimed shortly thereafter and low fuel light, and warning came on showing low fuel. A few days later the check engine light came on. I received a notice from gm in 2013 about a possible problem with early wear of the fuel sensor causing this problem. They covered the expense of repair up to 120,000 miles. We now have 134,000 miles on this vehicle and the problem just came up, so will not be covered by gm. I have read many complaints about this problem with the trailblazer online, so I know the problem has been identified by gm. I cannot afford the repair at this time and believe gm is not recalling this fuel sensor problem as they should be doing.

I can smell as if something burning, on different occasion.the headlights would randomly shut off, while driving. I would switch to high beam in order to see. The back hatch window, locks when it wants to. The airbag indicator lights come on and stay on awhile. The vehicle will stall and then accelerate at times. The tire pressure lights, does not come on when pressure is low. The check engine light comes on, and stay on awhile, and then goes off, and comes back on. The climate control heater system blows cold air. At one time the key would not come out of the ignition. Had to continue to giggle the key to get it out of ignition. Noticed my headlights did not come on when I used the remote entry to unlock or lock the door. The windows stall when going up or down. I have contacted gm , but they are telling me that my make,model and year are not part of the current recall. And that the letter they sent me, was to purchase warranty for the vehicle. I feel that this vehicle is not safe due to this electrical problems.

Vehicle stalls and shuts down everyday. Sometimes just stalls then accelerates, sometimes shuts off and I can switch to neutral and restart while coasting. Other times I get shutdown warning light and engine will not restart. I have to coast to the shoulder and wait. Engine will then struggle to restart and engine shakes violently. I wait a few minutes and it will start and run fine, sometime with check engine light on, sometimes not. Rpm gauge works sometimes, sometimes not. At time there has been no response when turning key to start. On going issue!! Crankshaft position sensor has been replaced 3 times, and issue still persist. Major safety issue!!

Gas gauge now has frozen all of a sudden after 50,000 miles. I filled up my tank full, started the trailblazer, and the gas gauge only says tank is 1/4 full!!! ? The check engine light goes on and off along with the ABS and stabilitrak lights. Sometimes they are frozen and stay on for days. I understand there are alot of problems with the electrical system on these vehicles! ? Unfortunately! :-( and now......the gas gauge too???!!! This does not make me happy! Always loved chevy vehicles! I don't know about anymore! How to rectify the gas gauge????

While taking my kids to school this morning, the engine shutoff shut off with no indication at all. We were starting to slow down to turn the corner to head to the school when this incident occurred. We have had several components (battery, ignition switch, alternator, starter relay) changed out the fixed the engine light, but the engine continues to stall. I have seen over 500 other people with this same issue and have not seen anyone who has had it fixed yet.

The service engine light came on. As I was driving home from work at night, the external and internal lights would dim and then return to normal. I later found out that the front lights would completely go out for a brief second or two and then turn back on. When I got home, there was an odd fan/vacuum noise from my engine. The noise was coming from the air filter area. The noise would turn randomly start and stop and run for several minutes. I unhooked my battery, but my battery was completely drained in the morning and the car would not start. I replaced the battery but the check engine light was still on and the noise would randomly start and stop, most noticeably when the vehicle was turned off. I took it to an auto repair shop and was advised the issue is the a.I.r pump relay - in-line6 and the a.I.r system pump - in-line 6. The labor description from the auto service states "check service engine soon light and abnormal noise from engine area. Perform diagnosis fault code p2431 for air injection system. Further testing found system not working at this time. Further testing found air pump relay connector melted shorted. Problem due to internal failure to secondary air injection pump worn needs replaced. I have my vehicle scheduled to fix this issue tomorrow when the repair facility can get the parts in. I was told this was a very common issue with the trailblazer. The auto repair man also told me that this puts a huge drain on the amperage, thus causing safety issues of the battery draining and the vehicle not starting in potentially dangerous situations. Additionally, with the air pump relay connector melted and shorted out - this is a potential fire hazard. I believe this issue should be covered under recall or warranty due to the frequency, known issue, and potential hazardous conditions.
