Battery Propulsion System problems of the 2017 Chevrolet Volt

While driving, a warning chime sounded and a message appeared saying "propulsion power reduced. " the check engine light also appeared. The car lost power, would accelerate only very slowly, and eventually died along a busy road. After a period, I was able to restart car and drive very slowly to dealer. I was told that the problem was a faulty egr valve, which was blowing a fuse and would do so again. Dealer was unable to find a replacement valve anywhere in the nation. Gm apparently is not manufacturing replacements for this components, and from reports found onliine, plenty of others have had the same problem. The temporary fix is to disconnect the egr valve, which results in increased vehicle emissions. I will be unable to pass my next emissions test next year. The safety issue is that the vehicle can quit running without warning in any situation.

We were driving in traffic. The battery had plenty of charge. Suddenly, there was a warning notice about propulsion power problem and the car converted to gasoline mode. We continued to destination and parked. When we went to start the car, it would not start at all. Had car towed to our local Chevrolet dealership (all service done there) and that is where it is still sitting. The part needed (battery) is on back order. This occurred on July 21, 2023. Today is March 13, 2024! as of today. . . . Approaching 250 days sitting in the dealership open lot,.

Prior to starting my 1,100 mi trip with my 2017 Volt premier, I inflated the tires, checked fluids, & charged the car. The monthly diagnostic report I received the day before my departure indicated no problems with the car, which had approx 40,500 mi. I was driving on interstates & highways using hold (gas) mode, occasionally mountain mode. Approximately 275 mi. Into the trip I received power propulsion reduced alert. After an additional 50-75 mi I received an action required: engine overheating reduce speed alert. I exited the interstate and proceeded to the nearest dealership to determine if it was safe to continue on my trip. I was told that the propulsion alert was not an immediate concern & that the overheating was likely not related. I also received a gm diagnostic e-mail stating there was an emissions problem that should be serviced within 7 days, but did not become aware of this e-mail until a day later. Approx 200 mi later, I was on a remote, unlighted highway when I received an engine unavailable alert and lost power. My car quickly decelerated, but I was able to get to a narrow shoulder. I tired to put the car in park, apply emergency brakes, and shut the car down but it was difficult to tell if these features were working. I put the hazard lights on and waited for a chp officer due to lack of cell service & highway safety concerns at night. After 3 hours, all systems failed, including lights. Only manual locks worked. After two 30 mi tows to get to a dealership with a Volt tech, it was determined that a bad egr valve was causing a fuse to blow,. The valve was ordered (tech remarked that the part is "popular") & installed. The issue seems to be fixed. But, it is unclear if this is a design flaw, manufacturing flaw, or a one time occurrence.

Propulsion power is reduced while driving. Power is lost and battery cells are drained chevy dealership claims they can not find error or address problem. After photo showing error on dashboard. ## #vpic# 1 - check digit (9th position) does not calculate properly #vpic#.

As I was driving I received a message on the driver info center to shift in park and I lost acceleration while driving. Pulled off to the shoulder contacted onstar to get vehicle towed to nearby dealer. Was pushed by two police officers to get off the side of the road on the two lane highway. Once towed to dealership the tow driver said I have drive and reverse capability again which I didn't have while put on tower. As I was stopped on side of road my driver info center stated propulsion power is reduced so I couldn't drive or reverse. Check engine was on that night and that morning. At the dealership, no codes could be read because check engine light went away.

For the propulsion many times while driving it occasionally slows down or speeds up kind of like a bucking horse. For the electrical the bluetooth connectivity to my cell phone and also my fob often disconnect and then I can't lock or unlock my car. For the other issue I have a shift to park problem that locks my car and I can't switch gears or turn the car on or off for a few minutes then it all of a sudden turns back on but the issue is that when it says shift to park it is actually in the park position.

My Volt had a sudden loss of propulsion and warning "action required - shift to park" and was in service at my local chevy dealership for 41 days to solve this dangerous issue. When the vehicle was returned to me it would no longer charge to 53 miles electric. On my level 1 charger it has charged to 52 or 53 miles since the first day of ownership on 1/24/17. The vehicle will change to 36 - 40 miles now which is greater than a 30% loss of electric charge. I am not referring to driving range which varies with conditions. The problem has been serviced by the dealership 3 times for a total of 53 days. The problem seems to have been resolved on the last service visit where the shifter assembly and the transmission control were replaced. I am now in arbitration with gm under the California lemon law and the bbb. I am requesting a buyback of the vehicle for impairment of use, value, and safety.

While driving in my son to school my check engine light turned on. Fearing my car would die with no warning (like had previously occurred) I went back to my house. I used onstar to pull the engine code of u18a2 which after researching online could result in 'loss of propulsion' like previously occurred. I called the dealer and had the car towed for service. After 15 days I received my car back and was told it was a loose electrical connector somewhere.

2017 Chevrolet Volt extreme engine hazard: on 22-Mar-2016 I purchased a 2017 Chevrolet Volt premier, all safety options. Driving on freeway at 65 mph, straight driving, relatively light traffic, the engine light came on yellow and steady (emissions system service warning) but the car uncontrollably decelerated. The freeway had no shoulder due to construction. The car smelled of burning electrical insulation confirmed by the tow truck driver. The car, with less than 150 total miles, in clear weather, at twilight, 76 degrees, California at sea level, straightaway, had a sudden and near total loss of all propulsion. This caused a lack of control (obviously) in the forward direction, causing an extreme hazard on the freeway. I am an experienced driver: make no mistake, this was a serious manufacture's error. I checked, no parking brake, the car was in drive gear, I had both electric range and over 7/8 tank of gas showing a gas range of 360 miles - and I had just driven 60 miles. There was no brake smell, as I did not need to apply the brake because the engine gave no propulsion. My hand was off the regen switch. The car had a major malfunction causing an extreme hazard, and based on the smell, possible fire hazard.
