Chevrolet Impala adaptive cruise 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 contact owned a 2008 Chevrolet Impala. The contact stated that while driving at 55 MPH while in cruise control, a group of birds flew out from under a ditch which caused the contact to swerve and lose control of the vehicle. As a result of the incident, the contact crashed into the ditch. The air bags did not deploy upon impact which caused the contact's face to hit the steering wheel. The contact was later transported to the hospital via an ambulance where she was treated for a concussion. Additionally, the contact suffered several cuts and bruises to her face with additional bruising to her left leg and hip. A police report was filed; however, the report was unavailable. The vehicle was towed to a dealer where it was deemed totaled. The manufacturer had yet to be notified of the failure. The failure mileage was approximately 150,000. The VIN was not available.

The contact owns a 2015 Chevrolet Impala. The contact stated while driving 40 MPH with the cruise control activated, the cruise control feature inadvertently deactivated, and the vehicle decelerated. An unknown warning light was then illuminated. The contact was able to accelerate, and the vehicle started operating normally. The vehicle was diagnosed by the dealer, and the contact was informed that the side detect module (B1010-00) needed to be replaced. The vehicle was not repaired, but an appointment was scheduled. The manufacturer was contacted and stated that the vehicle was out of warranty and referred the contact to the federal safety agency hotline for assistance. The failure mileage was 30,000.

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.

Traveling at 58 mph in Cruise Control for 10 minutes I increased speed with 4-6 rapid pushes of the Accelerate button in less than 1.5 seconds, Each push is 1 mph. I have never pushed it that rapidly.The engine acted as if I floored the accelerator & the transmission went from 4th to 3rd gear, speed went to 70+ and rapidly increasing. I stepped on the break pedal several times to disable CC but no help, I switched the CC button to the off position several times, no help. Now at 85+ and accelerating hard in wide open throttle (WOT). I shift to Neutral and turned the ignition to the ACC position to retain steering ability as the engine was RPM'ing out to destruction. I coasted off the highway and set ignition to off. After a few minutes I turned engine on and it rev'd out of control, still WOT. Ignition off did not reset the problem. I opened the hood to disconnected the battery & I observe that neither the CC or accelerator cables are not holding the throttle body (TB) in "WOT", it was closed in an idle position. It is not mechanical. I disconnected the battery for several minutes and then the system operated normally. I have used CC a million times but never have pushed that accel button that fast. I served 7 years as a Reactor Operation onboard US navy Fast attack Submarines, have torn apart and assemble mechanical and electrical reactor systems. I have been a Hardware Engineer for 40+ yrs and have 10 US patents in fault tolerant server design. I've been a car guy since 5 yrs old. This is a problem with the cars computer or its code. The rapid pushing of the CC accel button is key here as well as memory retaining this CC state after Key OFF. Its a good thing I experienced with many hard casualty life and death situations while serving, because my car was accelerating out of control, my experience and training in the US Military taught me to keep cool and think.You really should investigate this. I can tell you more specifics but I'm character limited.

I was driving on the interstate and the dash lit up service traction system and engine power reduced. I was currently using cruise control so it shocked me when my car went from 75 to 40 quick. I was in five o'clock traffic and almost rear ended. Check engine light came on as well. I'm planning on getting it looked at.

1. The display screen went black while driving using navigation. The fault was a defective hmi module, gm part # 84296482 at a cost of $1100 (see attached document). The sudden loss of the screen was disconcerting and could have caused an accident. This should lead to a recall and reimbursement of the repair cost. 2. When the adaptive cruise control (acc) causes the brakes to be applied it does so very suddenly and in the ABS "chattering" mode even when there is no collision danger. This produces a jolt to the drivers and occupants which is an unexpected and unsafe response.

Check engine light recently came on, car completely lost power and turned off during as I turned right at a light, had onstar run diagnostics, code involved the emissions system, was advised to fill up with high quality fuel, and drive with the gas cap off to correct it. I was traveling on a familiar highway at night, cruise control set at 60 MPH, further down the highway I see deer running across the highway, they are common in this area, I tapped my brakes to slow down for them to cross and immediately the check engine, antilock brakes, power steering, stability track and battery saver indicators illuminated on the dash and the car wouldn't brake as it should resulting in an accident that I had more than enough time to prevent and could have easily avoided if the brakes would have performed normally. Maintaining my vehicle and keeping up with its maintenance is of high importance because not doing so can result in safety issues,I travel a lot and if I had been informed of the brake recall or notified of possible other recalls I would have followed up and allowed gm to fix it!

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.
