2009 Chevrolet Impala fuel system complaints
Page 2 of 2: complaints 11 to 19 of 19, newest first, as owners wrote them.
I have noticed a sort of jerking or chugging feeling while traveling at different speeds and different environments, such as highway and city. The problem does seem to be worsening. The service technician at the dealership referred to this as a "fishbite". I did not seem to really notice the problem until repair was made to the manifold and crank case gaskets, due to a severe oil leak. The dealership did look into my concern for the "fishbite", but a code was not found and they were unable to duplicate the problem. Is this a precursor to the other complaints involving loss of power while driving?
Climbing up alpowa grade on highway 12 in washington state, the check engine light came on, "engine power is reduced" came on in the odometer window. Approximately 35 miles later, beyond dodge junction and before starbuck turnoff, there was another message flashed in the odometer window, "ignition switch disabled. Service engine" the engine shut down, and the power steering became super sluggish. The car slowed down, and we were able to get stopped on the side of the road. At this point when we got the car running again, the cruise control would not work. When we reached walla walla, washington, we stopped at o'reilys auto parts, had one of the parts specialists come out and check what the code was on the computer, and found out it was the electronic throttle sensor that is defective. This is a pilot car escort vehicle, making the hazard even more dangerous, because had I been traveling with an oversized load, I could have been hit by the semi pulling the load, or I could have impacted the rear of the load, depending if I were following or leading. Also, had that happened while on a job, the load would have had to stop until another pilot car escort vehicle could arrive to continue with the load. This is a dangerous thing to have shut off when driving in areas that are not straight. Unable to control steering, brakes less than responsive, and possible hazards of vehicles oncoming or following us could become impact hazards.

Tl* the contact owns a 2009 chevrolet impala. The contact stated that while driving approximately 70 MPH, the engine warning indicator illuminated then the engine stalled. The vehicle was able to be restarted 20 minutes later. The vehicle was taken to an authorized dealer for diagnosis. The technician detected that the accelerator pedal, accelerator position sensor connector, and fuel vent solenoid was faulty. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 70,000.
When I pressed down on my accelerator pedal (speed limit was increasing from 50mph to 65mph), a message of "starting disabled. Service throttle" came up on the dash. The accelerator pedal and steering wheel completely locked up and the car started to decelerate. I was able to force the steering wheel in order to turn onto a side street (narrowly avoiding a car stopped in the left lane to turn) and park the vehicle in a location out of the main lane of traffic. Had this side street not been there at that exact moment, the possibility of a crash would be very likely as steering was unresponsive and I may have been rear-ended due to the sudden loss of engine power.
Tl* the contact owns a 2009 chevrolet impala. The contact stated that while driving 55 MPH in cruise control, the vehicle began to stall. The vehicle also failed to increase speed when the contact depressed the accelerator pedal. The contact stated that the fuel gauge also failed simultaneously. The vehicle was not inspected or repaired. The manufacturer was notified of the incident and informed the contact that the vehicle was not listed under any recalls. The approximate failure mileage was 70,000.
Was driving around 65 when out of no where the check engine light and traction control light came on and the reduce to power message started flashing on the dash it dropped my speed down from 65 to like 20 while on the freeway.
The vehicle suddenly decelerated and displayed messages: "reduced engine power" and "service traction control". This was the second incident. The first incident resulted in the engine shutting off completely after the same initial symptoms described; locking up the steering during rush hour traffic (estimated 65 MPH, no injures, approx. 4 month ago). Our mechanic cleaned out the throttle body sensor after the first incident, and phoned the dealership with the trouble codes. The dealership refused warranty service as the trouble codes had gone by the time the car had arrived at their shop, and would not take our mechanic's phone conversation as evidence. We were informed that the three services commonly performed to fix the problem were to replace the throttle body, throttle body sensor, and accelerator pedal; the latter not covered under warranty.
Vehicle gives a service throttle starting disabled message and promptly shuts off the engine. If you wait 5 minutes the car will restart and perform as usual.....until the next time. Shutting off the engine at interstate speeds is incredibly dangerous and is going to result in someone being killed. Based upon internet searches this appears to be a known issue, but gm will not proactively fix the problem.
