2014 Chevrolet Impala acceleration problems

Filed Oct 24, 2025 · Acceleration, Electrical · IL

I previously owned a 2011 Buick Regal and now have a 2014 Chevy Impala. Both vehicles have had a Stabilitrack warning come up. Both vehicles experienced the same issue. The car seemed to jerk, lag in speed, cannot accelerate over 40mph. The Regal was diagnosed with an electrical/wiring issue. The Impala was diagnosed with a failed Transmission Control Module. We now have a 2016 Impala and the same issue and warning lights have appeared. That’s 3 vehicles we’ve owned from GMC with the exact same issue. This can’t be a coincidence and should be looked into. There are hundreds, if not thousands, of more consumers on forums experiencing the exact same issue. This should be recalled! Imagine the possibilities of danger this can cause when on the interstate and can’t accelerate over 40mph.

I have push to start car. On my lunch i starting my car and I immediately notice the rpm went to 2500, which is high and it went up to 3000 and then the warning light flashed stability track error and check engine and swerving light I took a pic.

Side detection system failure. I have had 3 harness replacements on driver side. 2 harness replacements on passenger side, and a module replacement just 2 years ago. This failure causes my instrumentation to shut off, turn signals not work, and shuts off cruise control when in use. I have read outher more extreme cases like engine compartment fires or car shutting off while driving. I believe all these should be considered safety issues. I have owned this vehicle since new.

UNKNOWN but I believe the sealed transmission is malfunctioning

When at a stop and turning left it makes a grinding noise with hesitation in movement. The ABS and traction control light comes on. When researching this, there are millions of these cars with the same thing. I have taken to 3 mechanics and no one can fix the problem.

There is a current recall on Chevy impalas with the trans mod control system but my vin number is not apart of the recall but my car is doing everything that recalls states. The recall number is 14V614000. The recall date 10-01-2014. My vehicle is 2014 and I have only had it for 2 years.

The 2014 Chevy Impala is dangerous. When the rocker arm control valve and related parts fail or the camshaft solenoids and sensors fail the car will drive rough and eventually just cut off in the middle of traffic highway or residential. This is what it did on me, putting me in a very dangerous position. The economic loss is still devastating financially as all 2.5 and 3.6 engines arent covered by GM special warranty but they should be all covered. My VIN number was not included when it should be.

The electronic parking brake fails to disengage entirely from the rear brake pads causing them to become welded together. This results in extreme heat, excess brake dust, poor acceleration, and caliper / brake line (air) issues.

It was a recall issued in 2014 for stabilitrak for bad grounds on my chevy impala and I went to chevy about it and paid for the diagnostics to check and they told me it was the transmission that I needed. Also, the paper doesn't tell me I needed a transmission fixed, so I took it to 3 different transmission shops and they said it was the ground that was bad. But I was not paying for it and it was a recall issued in 2014 that is happening and is happening to several others as well. I called the gm and asked if its anything they can do about it since it was unde recall they are saying no. And the I have to go pay for diagnostics again so they can see what it is because it may not be same and I did before and chevy said it was the transmission and the other shops said the transmission is in great shape it was the grounds thats bad and that if the issue was under a recall it should be done again. I take this as safety issue and it puts me and my family in danger and it is my only transportation . So I have my son picking me for work.
