2004 Chevrolet Impala


PostPosted: Sun May 26, 2013 9:03 pm    Post subject:  Sudden loss of acceleration and braking Reply with quote

Hey there. Today I left the mall parking lot in my 2004 Impala (Base 3.4L V6) and attempted to accelerate toward the intersection when I realised there was no power and when I attempted to brake it did nothing. I steered it to the edge of the intersection and put down my e-brake and turned the engine off; put it in park, and then started it again to have it work fine.

The only light that came on during this was the red battery light. I checked all fluids and they are fine. No overheating problems and the transmission fluid and oil was changed in the past month.

I'm thinking this is an electrical issue but I'm really not sure and can not afford to take it to a mechanic right now. I have an OBD/2 Bluetooth adapter somewhere so I'm going to try and find it and look at the engine codes to see if anything was caught in there.

Any ideas on what happened? Should I be worried about driving this until I get it checked out? I was really lucky I wasn't going faster than 30km/h when I lost my brakes.

Thanks in advance!

Even with the car still running, A/C and Radio and dashboard still lit up? The only things not working were brakes and acceleration (power steering may have gone too but it was too short of a distance to tell)

You didn't lose your brakes (or at least shouldn't have). More than likely you just lost the power assist. I had the same issue when my CPS was on its way out, you just have to really get on the brakes like an old school car to get the same stopping force. If you are convinced that you actually lost your brakes, do not drive the car until a mechanic can check it out.

I did definitely lose brakes. I pumped them until I couldn't push the pedal in any further (it was totally hard and wouldn't give at all). As soon as I restarted the car it all worked fine and there were no errors up on the dash.

If this happens again before you get it repaired, stay on the brakes, don't pump them.

If the battery light was on and you had no acceleration, it sounds like your car stalled. Mine would do that very rarely when moving at idle with a dirty throttle body and IAC. Clean everything and haven't had the problem since.
