2017 Chevrolet Volt: adaptive cruise control problems

Filed Dec 1, 2025 · Acceleration, Electrical · CO

The engine light starts blinking and telling me propulsion power reduced, and then I cannot use the cruise control after that turns on, and it starts losing power, driving on I 70 after work all of a sudden it turned on and wet from going 76 miles an hour to 52 on highway I 70 where the speed limit was 75. This problem was a recall problem which was fixed and now is happening again on the same part and having the same problems.

I was driving on a highway around 70 mph on cruise control, without warning a “propulsion power reduced” message came up with the check engine light turning on and the car stopped accelerating/let off of cruise control. Very dangerous when driving at speeds above 70mph. I took the Car to Chevy and they said it’s a EGR valve issue and that it would cost roughly $3,800 and the part is on massive back order. r Reading online, there’s many Volt drivers with the same issue and can’t get the part for months on (with some being offered a repurchase of the car from GM so the problem would go away) it seems like Chevy and or GM do not have sufficient parts to fix the massive amount of Volts having this specific problem and on top of that, this is the largest quote I’ve seen for this repair.

I was traveling at 75 mph with the cruise control on when a message came on about reduced purpulsion. My vehicle lost all power and rapidly decreased speed, the gas pedal did nothing until my speed had dropped under 60 mph. I was on the freeway and could have caused an accident. Chevrolet says a programming update was needed to fix the problem but my BECM is now also out.

On 2 separate time periods, "propulsion power reduced" message appears on dash: - 1st incident in November 2022, car would not move after powering off the vehicle. After sitting idle for a week, decided to retry, and car seemed to work normally. Took it in to Chevy service, they replaced the BECM. Car worked fine after this - 2nd incident in November 2023, again 'propulsion power reduced' message appeared. This time, however, car would suddenly cut off gas engine (even at highway speed), switching to 100% battery mode, and displaying 'Engine not available' on dashboard. Fuel level indicator would immediately display 'LOW' (even though gas tank was full). Reduced acceleration on battery mode. Car is now in same service center awaiting fix for the past month. Was quite an unsafe situation, especially at highway speeds, and especially given the fact that the battery also may have been at a low state of charge, risking complete vehicle breakdown. Coupled with both of these incidents, the cruise control intermittently shuts off, displaying 'Cruise control unavailable'. Car is lightly utilized, with just over 30k miles on the odometer to date. Additionally, the car is kept in a mild climate (coastal southern california) and parked in a covered spot shielded from sun and temperature extremes.

Was driving on the highway at approximately 70mph for a couple of hours, when I suddenly received a check engine light and "Reduced Propulsion Power" message. Engine temperatures were much higher than normal (220F-240F). Was able to get the car to a Chevrolet dealership eventually where they diagnosed the Exhaust Gas Recirculation (EGR) valve as faulty. There are no parts available for months. Any time that I drive on gas power at highway speeds, engine temperatures are high and cruise control has disengaged. This is a safety issue as I am not always able to maintain speed during extended highway driving when using the gas engine.

Several times since I purchased the car in Jan 2022, the left and/or right front brakes have dragged without brake pedal actuation while I was driving in surface street traffic, typically with speed limits of 25 to 35 mph. This has resulted in overheating of the brake caliper, rotor, and wheel. Typically the car can be driven again without issue after two hours of cool-off time. This phenomenon has occurred during both battery/electric and gasoline engine operation of the plug-in hybrid car. There are no instrument indications of a brake malfunction when it happens. It first becomes perceptible as a pulsation through the steering wheel and requires increased throttle pedal pressure to maintain speed. I brought the car to my local Chevrolet dealer after the first two of these incidents. Their first recommendation was a new set of tires to remove the influence of one mismatched tire. The new tires did not resolve the issue, and the dealer has not performed any other corrective action beyond a recommendation to replace calipers and rotors. Due to the intermittent nature of the failure and the fact that it affects both of the front brakes, I believe this is an ABS system issue and not a caliper/rotor issue, and I have not replaced those parts yet. The car's adaptive cruise control does not work properly. It almost always fails to set and shows "Adaptive Cruise Temporarily Unavailable" regardless of road conditions. This condition is intermittent and is not reproducible on demand. This condition is dangerous because it overheats the brake, wheel, and steering components. The heat may have damaged the wheel bearing, steering components, and CV joints. The heat also creates a risk of sudden wheel and/or tire failure while driving. The unexpected application of the brakes affects vehicle response to throttle and steering inputs, and has the potential to reduce driver control of the vehicle.

I'm having a shift to park issue with this chevy volt, it won't register with the system I'm in park mode. I'm also having an adaptive cruise control issue as it's telling me adaptive cruise control is unavailable at this time. The adaptive cruise control is a hit or miss.

After putting the vehicle in park, a warning comes up that says “action shift to park” and the vehicle will not turn off or recognize that it is in park. Also the heater doesn’t work at all at times in the winter and only blows cold air, finally after driving for two weeks only once a message that said service heater came on but that was in the summer. The cruise control intermittently stops working. I have asked CarMax to service when it was under warranty and they couldn’t find anything wrong with it apparently. It has happened numerous times since and now it’s not under their warranty of course. I have photos of it happening and a video of the cruise control problem as well. These things have happened multiple times not just once so to put in a date of the incident I do not have enough dates that I can even put in. I have added my three photos. The additional photos are other peoples comments about the same cruise control problem when I researched if this was a common problem.

Parking sensors malfunction often and error "service park assist". Sometimes when someone is less than 500 feet away and turning the car slams on the brakes which points to a radar issue. Also sometimes the adaptive cruise doesn't work (Windshield is clean) so we are without cruise control. Happened twice on a cross country trip.

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.

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.
