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 Chevy Impala will have the engine shut down. The warning "engine power reduced" "service traction control" will come on, along with the check engine light. You cannot accelerate, the car shakes, and is difficult to drive. Had the gas pedal and the equivalent part in the engine replaced (at different times) and had the codes come up in between the parts being replaced and still now. Took it into a Chevy dealer and it doesn't act up for them. And for whatever reason their computer doesn't show any problems. There are many complaints about this on different websites. I called GM and have a case opened to get help from them. It's extremely scary to have the engine power reduced while driving and it's very dangerous because you can't maneuver or accelerate.

Wife was driving home and the engine power was reduced and service traction control came up on the dash display. Power was cut, left her driving at around 40mph I drove it today, July 1,2014, it did fine for about the first mile then service traction control, reduced engine power display came on again. I drove it 4 times today, seems that if the car sit for a few hours, it ran fine, full power, no issues for about the first mile to mile and a half then it would come up with the service tcs and reduced engine power which leaves you at very reduced speeds. Luckily I live in the country so traffic wasn't a huge issue. I researched online and this seems to be a common occurance with many yr model Impala so I wanted to report mine so it would be on record as well. 2007 Impala LT2 with 3.9L engine. Thanks.

Impala

  • 151,450 miles
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 again.at this time car is unsafe to operate on any roadway because it might die and random times.

Impala

  • 80,000 miles
Once again the service traction control and engine power reduced lights are on. We have taken the car to don brown Chevy dealership multiple times with no fix in sight. Been told it's a clip that came loose and was fixed multiple times. It would be helpful to find some place that can actually fix the problem or for GM to come up with a fix. This is not a recall item and should be on the list due to the multiple incidents. This problem has been occurring intermittently on the car since 2009.

While driving my 07' Chevy Impala the temperature gauge arm often will drop to 'C' as if the engine temperature is cold, then the drivers information display panel will display a message "engine hot turn off A/C". I've had the thermostat replaced, radiator coolant drained and replaced, hoping to fix this problem, but I'm still dealing with it. After doing some research I'm finding that there has been other Chevy vehicle owners dealing with this same issue, which is most likely a bad 'engine coolant temperature sensor (ect).

Impala

  • 106,000 miles
I was driving to work and a message popped-up "reduced engine power" my speed was quickly reduced from 45 mph to 20 mph. I immediately pulled over luckily I was not hit by another vehicle. The check engine light remains on in the vehicle. I had the vehicle diagnosed and was told the throttle sensor need to be replaced. This is a dangerous issue that GM need to address. Numerous of Impala owners have filed complaints, but have been ignored. I feel as though GM should recall the vehicles and fix the defects... this is putting me, my children, and many others at risk. Please help with this issue.
