Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2007 Chevrolet Impala Owner Comments

My wife's 2007 Chevy Impala left her stranded on the side of a busy highway in a snowstorm. She was driving at highway speeds when all of a sudden, her overheat warning light began flashing, and what she described as "a huge cloud of fog or smoke" was trailing behind her. She immediately put on her hazards and pulled off to the side of the road. Once stopped, the digital readout showed "engine overheat, idle engine" and then the engine shut off. The vehicle is at a dealer awaiting diagnosis.

Reduced engine power/ traction control warning/ gas line fuel leak. This car flashed a reduced engine power message while I was going 65 mph straight away on busy city (in houston) freeway and the traction control warning light came on. My car then immediately reduced speed and would not go beyond 40 mph. I was told that the gas line fuel leak has nothing to do with it but it seems very coincidental that this all happened in the same day. GM is putting out a lot of trashy vehicles right now and this should definitely be a recall; especially when there are numerous valid complaints of the same issue. I'll never by GM/Chevy again. I am going back to an imported brand

While driving car started to jerk and hesitate the check engine light came on along with a message of reduced engine power. Could not drive the drive over 5 mph. Was able to get to the side of the road. Had to push the car into a parking lot as the engine will no longer start but cranks over fine. Had to buy a scanner to read the code because the car was not able to drive to a auto repair shop or auto parts store to read the codes. The PO641 code was set. Checked and tested the sensor wires for the 5volts every one that I tested showed ok. Replaced the gas pedal assemble because of the code that could be a source of the problem no difference. Cleaned the throttle body unit no change car will not start.checked and gave all the wires a good pull and or tug to wiggle the connectors and took apart all sensor connections no corrosion was found.all grounds appear to be good. No broken wires are found no blown fuses were found.after 2 days was able to start engine with the message reduced engine power and car died again and would restart but not idle. Was able to rev engine and keep it running but once it idled it would die and sometimes not restart this time car is unsafe to operate on any roadway because it might die and random times.

My wife's daily driver is a 2007 Impala. She was driving home with our three kids when the car started shaking and the reduced engine power display came on. After that she could only go about 25mph. This scared her and could have caused an accident. I looked online and found forums about a lot of people having the same problem and it pisses me off that GM hasn't recalled these vehicles. Does someone have to die before this situation is taken care of?

The fuel gauge does not reflect the amount of gas in the tank. It says full tank when it is but I ran out of gas on the interstate with it reading half tank. Dangerous!!! when it runs out of gas there is absolutely no warning, oh except you stall and have zero power steering. From 70 to 0 in 2.5sec. Called dealer and inquired about any issues with gas gauges becoming faulty and was told by service person that it could go bad but he knows no known issues with faulty gas gauges for Chevy. Looked on the internet and found pages and pages of documented fuel/gas gauge malfunctions stranding drivers. If they think ignorance is bliss then I have many other brands of vehicles to choose from.

The gas gauge needle and digital readout are off. Going 55 mph and the car just died in traffic. Gauge read 1/4 mile and digital readout showed 70 miles left. Topped off gas in tank to try and monitor and ran out of fuel again going by needle and digital readout. 74 miles left, just shy of 1/4 tank on needle. Now using trip mile feature to not be fooled by gauge and needle. "half tank" rule is now being used.
