2010 Chevrolet Impala engine problems

Filed Oct 18, 2024 · Acceleration, Engine · MO

I started my vehicle in the morning to let it warm up. I come back out to get myself and my son in the vehicle to go to work and take him to school. My dash upon entry had a check engine light on, and the message it displayed was "engine power reduced." I put my car into reverse, having no choice but to drive it and the traction control went out. My father in law pulled the code and it said something about the accelerator sensor. This is a known issue and recall in other models and I wanted to report it is also happening in my model.

The car can have moments of power loss where the speedometer suddenly, erratically spikes while the tachometer slightly lags. It almost stalled my vehicle while transmission was in drive while stopped. It feels like dragging when the power loss occurs. This has occurred randomly for the past month, mostly during interstate driving with cruise control operating. It has happened the last six times I have driven, but the previous several times it did not occur. It also occurred in a similar random fashion for the prior two weeks. When it does occur it feels like power drain and deceleration that can last a second and this will occur several times during a twenty minute drive at 70mph. Mechanics at two shops seem confused and don't know where to begin except for a transmission fluid flush. That was completed and the problem has persisted. There are no related error codes. To lose power suddenly and unexpectedly could cause an accident especially if a system failure shuts off the vehicle while driving. This vehicle has had an oil consumption/burning problem since I bought it with around 60,000miles. It needed 2 quarts of oil added between the last oil changes. I have spent $1400 in July of this year on gasket replacements and that did not stop the leak. More gasket heads and an oil pan are going to be need to replaced and the estimate is another $1400. This is too much to be spending on possibly related issues in a short time span that may not resolve the problem.

Sometimes when driving an "engine reduced" warning will pop up and when it does so, the car limits the amount of power applied when accelerating. I have to turn it off and sit a few minutes before it goes back to normal.

Suspected failure of wiring harness altogether with possible bcm/cam failure as well. During battery test there was a regular drop in voltage while connected to the scanner reflecting a drain in the electrical system that could further be causing an issue.

My car has worked fine scince I bought it with no check engine codes.I pulled into parking space and put car in park,all of a sudden it stalled out and will not crank anymore but has power.key will not come out of ignition and battery will not shut off.the ignition switch is a very common problem with impalas and is very dangerous.it locks people out of there cars,gets stuck in gears,wont let key release,wont start,sets off anti theft signal which cuts power to door locks,trunk,starter,fuelpump,and more.I have read hundreds of forums of this problem with chevy impala that has been going on for years without the problem being fixed.elderly women breaking down on highway or car just shutting off and not restarting.it is soooooo common with chevy that they can diagnose the problem just over the phone.this is very unacceptable and has to be dealt with.please recall this problem.
