2017 CHEVROLET VOLT Complaints

The latest episode with my 2017 Chevy Volt is a culmination of years of issues with the low clearance on the vehicle causing continual damage and unsafe driving conditions that require expensive repairs due to the design flaw (note - I had a 2014 Chevy Volt that had NONE of these problems). My son was driving the car a week ago and the Engine Control Module (GM part # 12700116) fell OUT of the car. This led to the car to stop driving instantly - if he had been anywhere other than a quiet residential street it could have been catastrophic. Upon having towed the vehicle to the dealership, I was informed that the wiring harness failed which led to the ECM falling onto the street. I drive this car strictly in city limits and on major highways, and despite this the bottom undercarriage is constantly damaged because it is simply to low to the ground. In addition to the repair bill of $3K+ (my 4th repair required due to this defect), the harness isn't even available and GM cannot provide an ETA for when it will be. I experienced a similar issue 6 months ago when a part was backordered for 3+ months and this is compounded by the fact that their dealerships no longer have loan car inventory. Note that there was no warning before this happened. I have tried escalating to GM but their response is essentially that I am SOL. Again - this is a design flaw of the vehicle that should have been addressed but never was. Note that this doesn't include the other continual issues (well documented) that continue to plague the car after other recall service (loss of propulsion, shifter issues that frequently make it impossible to actually turn the car off, etc.)

Vehicle periodically throws P0964 and P0AC4 related to TSB PIC6330. Recently, this has led to poor running of internal combustion engine and low/undrivable power, almost leaving me stranded. Took multiple restarts before I could drive the vehicle. The TSB indicates to replace part# 24285319 (internal transmission solenoid control harness) however GM indicates they have discontinued manufacture of this part. How am I supposed to get my 6 year old car fixed if GM doesn't supply the part?

EGR valve failed. Dealer supplied part has been on back order for more than five months.

All of a sudden while braking on a freeway offramp, the check engine light came on and a reduced propulsion warning came on my screen. The car ran weird for about a day, then it wouldn't start. I had it towed to a dealer, they diagnosed the BECM went bad, now my car has been there 2.5 weeks and there's no estimated ship date for the part, much less repair date. If they said they had enough parts for BECM failures, they're either lying to you or they're lying to me.

I was driving and then the car turned off and was unable to restart. There was no warning. The car was fine and then it wasn't. The power steering also stops working. Fortunately I was at a red light and not in the intersection yet. The check engine light wasn't on. The BECM (battery control module) failed. I had to get the car towed to the dealership for the repair. The dealership repaired the issue for free since I was still under warranty.

The BECM located in the battery compartment failed The vehicle was completely immobilized and would turn on but would not "start" leaving me stranded. Away from home. The local Chevrolet dealership confirmed the BECM was at fault The vehicle gave no clear indication of a pending BECM failure before the failure

The contact owns a 2017 Chevrolet Volt. The contact stated that while driving approximately 65 MPH, the vehicle suddenly lost power and decelerated to 35 MPH. During the failure, the message "Reduced Power" was displayed. After turning off and restarting the vehicle, the failure remained, and the vehicle was driven to the residence at a reduced speed. The cause of the failure was not yet determined. The manufacturer and local dealer were contacted. The failure mileage was 26,000.

The contact owns a 2017 Chevrolet Volt. The contact stated while driving 65 MPH, the Hybrid battery drained; however, the engine failed to activate as needed. Due to the failure, the vehicle stalled, and the contact coasted the vehicle to the shoulder of the highway. Due to the failure, the vehicle was initially towed to the residence then to the dealer. The vehicle was kept in dealer possession where repairs were made to the ECM (Electrical Control Module). Since the repair, the contact stated that the vehicle intermittently failed to start up while depressing the START/STOP button. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 20,000.

Consistent BCEM failure with volt. Power Reduced even if battery has full charge and gas is in tank. Forward Collision made unavailable without reason whilst driving. I rely on the forward collision system while driving at night in my area because of drivers cutting each other off constantly, so losing this feature without knowing why it failed feels unsafe to me. Forward collision would also activate when no vehicle is infront of me causing the car to suddenly stop and jerk on the road. Propulsion power is reduced is an extremely common occurrence in my volt. It happens randomly while driving and even while charging. When I'm on the highway the car would slow down when the warning came on; even with cars right behind me. I'm scared one day the car's system will cause an accident because of it's unpredictability. Regular maintenance has been performed and no issues have been found. The problem continues to persist.

EGR failure can cause the car to become immediately inoperable w/ no propulsion due to fuse pop. EGR required to pass emissions regulations but none are available.
