Cruise Control Problems of Chevrolet Volt

We own two 2017 chevy Volts. Both have two issues: 1) often cruise control does always stay engaged due to brake pedal slipping to a very slight depressed position. 2) shift-to-park- cars will not properly go into park sometimes and thus cannot be turned off. These two issues are clearly manufacturer defects as both cars were bought new and within a month of each other. I will enter this for my other VIN number as well. These have been ongoing issues that we are having to spend money to correct and there are many reports of these being issues, yet there is no recall. We purchased both cars brand new within a month of each other. Both issues have been ongoing and have occured more than once.

The cruise control does not work every so often. It seems to happen when I use a lot of the steering control to increase and decrease the speed. It's I took it to the dealership 2 times and they can't find the problem. I don't have specific dates when this happened but it happens enough. Other things that happens are 1) the Volt has a charge setting that optimize to start charge delay depending on when you schedule when you plan to leave so the car will not be left fully charge for a long time. However, the estimated charge time is completely off now. It seems to think it will take 12 more hours to charge. Therefore, the car would start charging a few hours earlier than it should. 2) the audio system connected to the smartphone is very buggy. Sometimes the display shows music is playing but no audio.

My 2017 chevy Volt has an adaptive cruise control problem . It will only work when it wants to but what make it so dangerous is that if you get it to engage it will randomly and without any warning disengage itself. If you are using the 2017 Volt in the low gear mode and this happens the car will rapidly decelerate which is very dangerous and has almost cause the people behind me to run into me. I have tried to get this fixed several times but it seems nobody knows what to do with it and they will try but it just goes right back to doing it again.

While driving on city streets and highways, the adaptive cruise control will not engage 25% of the time and will disengage without notice. "adaptive cruise control will appear in dic. However, this creates a safety hazard as you never know if the car will automatically slow down. I have filed case # 9-5379585813 with Chevrolet and been to four dealers and they refuse to fix the problem. They no longer return my calls. I am afraid to use the cruise control.

Un-commanded vehicle acceleration under full electric drive mode (twice). While driving steady around 65 mph on the freeway (no cruise control used), a slight step on the accelerator, caused the car immediately accelerated up to 88 mph (dash show large electrical draw of battery power). Stepping on the brake, using the regen paddle on the steering wheel and repeated pressing the cruise control power didn't disengage the power surge. Car would accelerate when brake pressure was lifted. After repeated hard pressing of the brake pedal, there was a "clack" sound from below the driver console and the car returned to normal. Being on the freeway, I was not able to pull over and restart/reboot the car. I continued to drive cautiously, monitoring the car and left the freeway for surface streets. Everything seemed to be okay until I came to a complete stop behind traffic. When traffic started moving again, I lightly depressed the accelerator pedal and the car began accelerating quickly on it's own. Several hard presses of the brake pedal and the car returned to normal. This second incident was not as violent and the first and there was no "clack" sound from below the driver dash as with the first. This is worrisome and cannot be related to the cruise control since is was at a stop and cc isn't supposed to engage under 25 mph. The rest of the several miles to my work was uneventful. I've contacted the dealer about the safety of driving it or having it towed. Waiting for their response. I imagine the on-board computer would've stored today's driving data.

Adaptive cruise control unavailable randomly occurs while driving using adaptive cruise control. Presents a large danger of hitting other vehicles if the adaptive cruise control is used to come to a complete stop as it will randomly disengage while coming to a stop. Cruise control only works 4/10 times attempted and was "fixed" by the dealer with less than 500 miles on the odometer. However the problem recurred within a day. Looked it up in forums and it is not an uncommon problem. Holding foot under the brake pedal allows cruise control to work but is more dangerous than randomly cutting off. No one in Volt forum has gotten a complete fix to date. When they do I will be getting mine repaired armed with the correct information. But it is dangerous.
