Noticed a strong smell of gas after refueling one day, a few days later noticed gas leaking from the tank while it was parked in the driveway. Took tank off and fuel pump was rusted almost all the way through. The mechanic said that he had the same thing happen to another 2007 tahoe just a few weeks prior.

When traveling above 30 MPH then decelerating, once the car gets to around 15-20 MPH it jumps forward. It's similar to when you drive a stickshift and take your foot off the clutch and the car jumps forward as if it might stall. It doesn't happen regularly. If I decelerate very quickly, then it does not do it. If I decelerate slowly then it does not do it. It has to be somewhere in between and the car is confused between staying in gas mode or switching to hybrid mode and auto stop. The car then jumps forward when confused.

I drove my vehicle in the morning and then parked it for about 2.5 hours. When I started my vehicle the gas gauge showed my car was empty, even though I had just recently filled up and had only gone about 80 miles on the tank, my airbag readiness light stayed on, and none of my gauges were functioning. Also, the light for the passenger air bag above my review mirror didn't illuminate at all. I drove it for a few seconds and tried turning it off and then back on, but nothing changed. After driving it for a few miles, I parked and turned the vehicle off again. When I turned it back on, everything began working again. I believe this is an electrical issue, but when taken to the dealership, I could not get it to replicate the issue. Besides the obvious danger of not having any gauges while driving, my fear is that the airbags would not work properly in an accident.

Fire hazard explosion hazard environmental hazard. While in motion pressurized fuel lines at the furl pump can unexpectedly fail due to corrosion resulting in fuel being pumped out of the vehicle onto the under surfaces of the vehicle and the roadway. As much as 25 gallons of fuel can be expelled from the vehicle while in motion with no warning to the driver other that a rapidly diminishing of amount of fuel remaining as shown by the fuel gage. The vehicle was being driven on an interstate highway when the fault occurred but it was not noticed until the vehicle exited the highway at which time a strong odor of gasoline was noticed. When the engine was shut off and the vehicle exited a pool of gasoline was observed under the rear of the vehicle. The vehicle was towed to a repair facility. During the repair it was noted that the fuel pomp is located at the top of the tank and could be observed without removing the tank from the vehicle. Upon removal it was found the pump mounting lacation was in a well molded into the plastic fuel tank. The well was full of sand and dust which was cleaned out revealing a mass of rust on the steel fuel pump support and locking ring as well as the steel pressure and return lines. The leak was determined to be in the pressure line line inside the plastic fuel line quick connect both steel fuel lines disintegrated while attempting to disconnect the plastic lines from the tank.repairs included the replacement of the fuel pump, both plastic fuel lines and quick connects.these components are identical.to those originally installed and will be subject to the same corrosion as the originals due the to the poor design of the pump placemen ton the tank and the failure to shield the components from being covered with sand an dust, particularly in areas where salt is used on the roads in winter.

Takata recall. Between 2010/2011 side curtain airbags (front and back), deployed while operating vehicle in optimum driving conditions, after a passing over a pothole in the roadway. I was traveloing with my then [xxx] son and daughter. Imeediately took the vehicle into the dealership only to wait over a month, without a vehicle, and never given the option of a rental or loaner vehicle. As "chevrolet" investigated the on-board computer data, it falsely read that airbags deployed due to "rollover event" data was sent to the vehicles SRS system. Chevrolet then deemed that I was driving over 95 MPH (which is impossible due to the rev limiter), and I had oversized wheels on my vehicle. Wheel diameter and size were not the factor, as they were within 5/32" of oem stock dimensions. I was charged for "troubleshooting", as wewll as labor for the removal of the side airbags, and they declined the claim. Additionally, I have had to reyturn to the dealership to again "warranty" the ECM, bcm, window regulator (twice), as well as charging system faults. My extended warranty was again denied saying it was not within the parameters of the coverage. Full extended warranty, bumper to bumper and this was not covered?

Around feburary of this year my vehicle begin to idle out of control and was attempting to gun off evertime I tried to put it in drive, according to gm they were already aware of the issues and said they had an extended warranty on the throttle body for my 2008 chevy tahoe. My car did exactly what gm said it would do to confirm it was the throttle body but the gm service department denied the issue claiming it was a loose vacum hose and would not replace the throttle body. My vehicle still does not operate as it should which I know is due to the throttle body issue. Thousands of owners have confirmed the same issue and obviously gm knows about the issues but chooses to go around it by calling it an extended warranty which makes the replacement conditional. I am 100% sure that I and milllions of tahoe owners know this she be a recall and not a so called extended warranty to get around the expense of making a recall. When the issue occured I went flying down the freeway with minimal ability to slow the vehicle down, I had to drive my vehicle to the shop by riding my breaks because the vehicles throttle body would not let the trucks RPM go below x3000. Gm is continuing to ignore this serious issue and will untill someone dies instead of taking responsiblilty and making the recall to prevent the loss of life.
