2014 Chevrolet Impala: adaptive cruise control problems

Filed Apr 6, 2025 · Acceleration, Driver assistance · MI

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.

The brake light in the window flashes on and off all the time and even when car is parked and shut off it flashes and when it is in motion. The cruise control will not work and device stability traction control warning is on and says it needs to be serviced. Vehicle only has 28000 miles on it.

Driving along on freeway when all of a sudden my dash lit up with various flashing lights and warnings, the cruise control shut off and my HVAC stopped functioning. Had to pull over on busy highway and restart to no avail. Pulled over again once I got to rest stop. Let it sit. Restarted and worked okay. Internet says problem is with side detection system (which dealer confirmed but said my car missed cut-off date by 5 days on a $700 repair bill. Car has but 12,300 miles on it (I am 92 years old). Internet also states that if issue is not fixed it will eventually cause serious issues with dashboard electronics, including fire. Gm issued special coverage adjustment #n172097060 (no owner notification), which is what I was told I missed out on by 5 days.

The cruise control button sticks, when being pushed it clicks hard to get to work. The most important started a couple of weeks ago with the steering wheel on moving and pushing the gas makes a clunky and grinding sound and feel, the vehicle does not go anywhere then, the stability light comes on. The car starts moving, and the wheel frees up and the light goes out. This is every time I'm turning left after from a stopped position.

While engine running and vehicle is stationary and/or in motion the brake lights flash intermittently. Brakes do not engage, but it does cause cruise control to disengage. Saw a recall for this, but my VIN not included.

Traveling at approximately 65 MPH with cruise control engaged, I pressed the acc button to increase speed. I released the button when I reached the desired speed (72 MPH) and the vehicle continued to accelerate. The pace of the acceleration was much faster than normal use of this feature. (it felt as if the accelerator was floored). The speed increased to between 85 and 90 MPH before I could react. I turned the cruise off and immediately the speed began to decrease. This occurred on an interstate that was fairly flat.

Forward collision avoidance system inappropriate activation on several occasions at different locations. There were no other vehicle in front. There were three beeps/red light flash on windshield. The cruise control would deactivate and car would decelerate by three to five mile. The tail lamps are not activated to warn drivers following. This is my second complaint the dealer solution is to turn off the feature. It work when it should the inappropriate activation is a nuisance.

Experience on multiple occasions the forward collision avoidance activation of a flashing a red light from dash into the front windshield and sounding an alarm with three or four beeps. Referring to this as phantom braking activated by the forward collision avoidance system causing autonomous brake activation and the cruise control disengagement. It is unknown if the activation of brake lamps occur I hope they work when this happen. My service manager suggestion is to deactivate feature.
