What owners say about the vehicle speed control
Verbatim from NHTSA complaints, newest first
“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. I turn car off and wait a few min turned car back on and it was fine. No errors drove to get lunch and back no issues. Then on leaving work s ame thing happened but the error didn't go away. I was able to shift out of gear. Hard knocking, gear shifter light all white no clue what gear it was in I moved to another parking spot but was slow moving very delayed. Parked and now waiting for tow truck”
“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.”
“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.”
