2016 Chevrolet Volt

my forward proximity sensors would randomly trigger. One day my ambient air temperature went haywire, checked for codes and had high voltage reading ambient air, brake booster trouble. after further investigation found that the X100(female) connector had water intrusion causing shorts across the pins showing voltage to drop across other pins further sending false or incorrect signals to the computer. the connector was thoroughly cleaned and aired out. now wrapped intensively with a lot of electrical tape in hopes to prevent water from getting in and causing voltage that range from 5v-14v from shorting across terminals and causing false activation.

vehicle suddenly stopped while driving , engine light came on and on board charging system maintenance showed on dash display , I was able to restart it and take to the dealer for diagnosis they said that the BECM needs replacement at the cost of $2500.00 and that it is common on this vehicle ,this issue is a safety problem GM has issued a TBS for this defect recognizing it as an existing defect, this would cause a tragedy if it occurs while driving a on the highway ,since the car would loose power and could cause a catastrophic accident . the cost of the repair for a known defective part is unfair to the consumer and should be the manufacturer responsibility to bear the cost for safety .

While on a road trip, we were traveling on a rural highway at roughly 55 mph. We received a warning message on the dashboard stating that "Propulsion power was reduced" and the engine began running rough, with surging noticeable based on throttle position. We also noted that engine temperature was rising above what was typical for the vehicle. The vehicle was able to maintain highway speed, and we were able to limp the vehicle to a safe location. Based on a web search, we were able to diagnose the issue (a failed EGR valve) as well as a way to limp the vehicle to a local dealership. They made a change that allowed us to limp home safely (unplug the EGR valve's electrical connector and replace the blown fuse under the hood). The vehicle was taken to a Chevy dealership when we made it home. The failure we had diagnosed was confirmed, and the component was replaced. The repair was not covered under warranty, and cost a significant sum to repair (1139.91). Additionally, this appears to be a very, very common failure for this make and model of vehicle- to the point where there is so much demand for this repair to be performed that these components (the EGR valve specifically) are difficult to obtain from Chevy. Additionally, the failure mode is such that when the EGR valve fails, it pulls excessive currents, and blows a fuse that also controls a number of important engine cooling components, leaving engine cooling significantly compromised. If we had been going faster, or if the weather was warmer, or if the load inside the vehicle was heavier, it would have been easy to overheat the gas engine and leave us stranded. I am concerned about the incidence rate of the failure, (based on online reports) the relative small number of miles on the vehicle when the failure occurred, (~57k) and the possible knock-on effect of the failure of the gas engine's ability to cool itself due to a relatively unrelated failure.

Got a Check Engine light on Aug 26 2022 driving about 5 minutes out of my house. With that light turned on, the EV showed zero miles range (it was fully charged when I left the house), the ICE engine kicked in but it was running very harsh and when I stepped on the gas peddle, it would not accelerate and can only go about 30 mph. I immediately made a U-turn and returned home for the car is not drivable. Took the Volt to my dealership on Aug 29, 2022 and service manager diagnosed as a BECM failed and now waiting for a replacement, which they said they are not able to find one. This is going on week #7.

The contact owns a 2016 Chevrolet Volt. The contact stated while driving 55 MPH, the battery level indicator was fluctuating up and down and then the instrument panel went blank. The vehicle was not diagnosed. The manufacturer was contacted and stated that the vehicle needed to be diagnosed. A case was filed. The failure mileage was 160,800.

Received a Reduce Power warning with a check engine light on. OnStar e-mail notification saying there is an issue with Lithium-ion battery and to service the vehicle within 7 days. When this happened I was driving on the street not far from my house and sure enough I was not able to keep up with the speed of the traffic so I turned around and returned home. My battery was fully charged when I left home and when this happened, it showed my battery was depleted and switched to my gas engine but was not able to drive over 40 mph for the gas engine was making a weird sound as if it is not able to run smoothly.

My car, without warning, lost power while driving and then flashed an engine light. This happened on a street and I was able to coast to safety, but if it had happened in an intersection I would not have been so lucky. The problem was confirmed by a dealer as a failure of the Battery Energy Control Module, which has been happening to this car with numerous other owners, according to the Volt owner website.

When attempting to power down the car, a message, “Action required, Shift to Park” appears and car will not power down. After repeated attempts, sometimes requiring 10 or more, by re-starting the car and attempting to power down, it has eventually powered down. This problem is intermittent and the car WILL power down successfully repeated times, and then do it’s “shift to park” refusal to power down. There are hundreds of complaints on the GM Volt owners’ forum and even a Technical Service Bulletin No. 19-NA-206 dated February 2020 (maybe even more recent, but that’s the latest one I know of). The service bulletin also includes the Chevy Blazer, Malibu, Traverse and GMC Acadia (which, I understand, there is now a class action suit in that regard). If the car will not power down, it could drain the battery and leave the driver stranded, as well as making the car unable to be locked, which could also be a safety issue.

Action Required Shift to Park message comes up on the dash after starting the vehicle & shifting into gear out of Park. The message goes away when shifted back into Park, but the vehicle doesn't respond when shifted into gear. Reverse, Neutral, Drive, Low - none will engage. I had to repeat the process of starting the vehicle 28 times before it would operate as it should. Start Vehicle to View Application message comes up when in Park & trying to shut the vehicle off & will not power down until the driver door is opened. I worried that I'd be stranded if this continued to happen & took the vehicle to Brad Deery Motors in Maquoketa, IA for repair on 4/14/22. I paid $736.71 & the invoice states: 106128 shift to park, diag, intermittent open in the shift park solenoid, replaced shift park solenoid and jumper harness, tested working properly. I brought the vehicle home & had the same messages appear on 4/19/22. I have since read a forum on the Volt & understand that this has been a common issue & found a service bulletin: 19-NA-206, but wondering if there is an actual recall. I plan to contact GM regarding this issue.
