I purchased my vehicle in August of 2020, in October while driving down a main highway the engine light came on with a warning that stated "driving with reduced power". The vehicle slows to 20 mph and will not accelerate any faster. I called my dealers service center and was told this issue was a "quirk that happens" and to "turn my vehicle off and start it again" and that by doing this it would make it go away and it would not happen again. Approximately 8 months later this happened again, so I called the service department and was told that a line was freezing and that I could bring my vehicle in so they could empty & refill the frozen line costing $500, but it would not solve the problem, the dealer then recommended that I park in a heated space to avoid it freezing, but again it would not resolve the problem long term. A month later while driving home from work in a blizzard, my vehicle once again lost power, with the engine light on and a warning that I was driving with reduced power and slowing to 20mph. This put myself and other travelers on this busy main road at risk. When I reached out to my dealer they said that there was nothing they could do that would guarantee a fix, but they could try three different options, again with no guarantee of a fix. None of this is covered under warranty and costs roughly $1500.

The vehicle constantly reduces speed when there are no issues with weather or any other issues on the road. This issues can potentially be fatal. I have had it checked and the diagnostic machine says it’s sensor issue that was reported for recall but my car was not part of the said recall. The car completely shuts off and will turn on by itself after 10 minutes. Uncertain what to do

On January 2022, Wednesday the 19th. My husband, myself and our two daughters 12 & 4 are on the Northbound freeway 99 in the far-right lane and the car pops up with the warning “Engine Power Reduce” and then proceeded to decline in speed from 70 MPH to 15 Mph almost instantly almost causing an accident. WE all were so shaken up! Had we been in front of a big rig we would have been crush from the backseat as fast as the speed declined. WE just bought this vehicle 5 months ago no more than 10K miles on it. The dealership says its not there problem to contact GM. Nobody will help this is a death trap vehicle. There are already multiple class action lawsuits about this issue and the vehicle. We are simply being told to buy a newer vehicle rather then someone taking ownership of this issue. This is a deadly issue and why there is not a recall is outrageous, There are cars out there that are capable of causing a deadly crash and killing thousands of people and everyone is turning there head when the consumers are reaching out for help.

An error message appears on the dash, ENGINE POWER REDUCED. It happen three times this morning and twice yesterday - probably a dozen times over the past year. I've had it into the dealer but they could not find anything by the time I got there. It has happened at 35 MPH and between 45-55 MPH, suddenly and with no other warnings. Turning off the engine for a few minutes clears the message on the dah, but the check engine light remains lit. The check engine light will clear eventually - it may be a few hours or two days of driving. Again, I've had it checked on multiple occasions as the car was "certified" by GM, but now the warranty has expired, the issue continues and I see a LOT of reports of the same online.

Car voltage stays very high (between 14.8 and 15 volts) for extended periods of time. At which point the windows have fogged up and there is a raw egg smell in the cabin - probably Sulfur. Both the hybrid and the 12v car battery are located in the truck and there are vents that draw air from the cabin to ventilate those batteries. The car voltage will also stay at 12.5 to 12.6 for extended periods of time. During both high and low periods numerous internal systems have failed, including bit not limited to steering assist, anti-locks bakes, Stabilitrack, On star, Hybrid Control Processor and ECM. Car has been brought to the dealer 3 times. First time (early November 2021) it was diagnosed with an hybrid inverter and a software update was installed. Issues continued. As of 12/28/21, Coggin Chevrolet (Jacksonville, FL) has had the car for 2 weeks and can't fix or confirm what is wrong with the car. I have received numerous e-mails from On-star with engine error codes as well as 5 messages saying there is an issue with the Electric Drive Unit in the car. The car has roughly 24K miles on it.

Driving on highway at about 65 mph on family trip to Delaware. . Car suddenly gave reduced acceleration error and speed started declining while in traffic. No warning.checked chevron app on phone and it did not see anything wrong. There was NO check engine or anything. Got to a dealer and they said it was probably a sensor for gas pedal. 5 days later driving home to Georgia from trip on highway around same rate of speed. No warning . The check engine light and reduced engine power warning message came on. This time the Chevrolet app notified me of trouble and said I needed the car seen within a day. .Got to a dealer and now they say they think it may be the cam shaft based on the code but they cannot replicate issue. I took a photo of the alert from the second incident . Car has about 46,000 miles and is well maintained . Our safety was at risk both times but especially the first time as we were in traffic and speed declined .

Was driving to work at 5:00 am today and merged onto a busy highway. After accelerating to 60 mph, there was a message that appear on my dashboard that read engine power reduced. It was not safe traveling at the speed that I was. The check engine light came on as well as the Stability Control symbol and my car reduced its speed and would not accelerate back to a safe speed. I am going to take it to the dealership and try to get the problem diagnosed. I really hope this issue gets resolved.
