1 Engine And Engine Cooling problem

Failure Date: 07/06/2024

7/6/2024 was driving 45 mph on a busy road (running only on the gas engine of this plug-in hybrid). Propulsion power reduced message showed near the speedometer. My speed was immediately decreased. The check engine light also came on. Despite pressing the gas pedal, the speed could not be maintained and I had to pull off quickly before causing an accident. Luckily, no accident occurred but I fear would could have happened if I wasn't in the right place to pull over quickly. After getting the car towed to a chevy dealership, they diagnosed the problem as being with the hybrid battery - it needs to be replaced. I don't understand why I had a full tank of gas, was running on gas, and that a bad ev battery would cause all propulsion to stop so quickly.

4 Engine And Engine Cooling problem

Failure Date: 11/01/2021

I'm constantly receiving a "propulsion power loss" notification on my car. I have brought the car in to a Chevrolet dealer and they refuse to fix it unless I start paying out of pocket costs because the ticket is "closed". This has been going on for about a year since I purchased the car last November and I'm terrified to drive this car since it literally looses power.

5 Engine And Engine Cooling problem

Failure Date: 10/29/2019

Volt loses power when switching from electric to gas motor. Has no occurred two times, both resulting in a tow bill. Te Volt depletes the onboard battery charge and is then supposed to switch ove to the niternal combustion engine. Instead, at the time of transition the vehicle loses all propulsion power, power steering, etc. The car comes to a complete stop and will not move. This has happened on a multiple-lane freeway and is very dangerous trying to maneuver a vehicle that has no power to drivetrain or steering.

6 Engine And Engine Cooling problem

Failure Date: 07/08/2019

Volt loses power when switching from battery to gas. Has now occurred four times. Each time Volt is traveling on highway 65+mph. Volt depletes battery charge and immediately upon transition to gas will lose all power. Cannot accelerate. Steering wheel loses power steering. Volt will decelerate until 0 mph. Very dangerous. In each instance driver is forced to get to shoulder or off freeway in Volt which is rapidly losing speed. Occurred on highway without shoulder last time. Almost caused a serious accident.

7 Engine And Engine Cooling problem

Failure Date: 02/17/2019

Vehicle dies suddenly while moving, although under full electric charge. Could not restart. Chevy said was software problem and made fix Dec 2018. Just happened again yesterday 2/17. Others reported on Volt blog site. Said wait 5-10 minutes and then restart, which I did and that worked. Concern that loss of power is sudden and without warning. Died in middle of intersection this time but fortunately no cross traffic. This is serious problem -- apparently others have had same issue. Reporting to local chevy dealer at this time.

8 Engine And Engine Cooling problem

Failure Date: 01/16/2019

My 2012 chevy Volt has completely shut off at freeway speeds, and surface streets on over 15 occasions. The power steering assist goes out, the brake assist goes out and it's very difficult to steer and break the car, I have nearly avoided several accidents, there is no warning that this will occur. The power steering assist goes out, the brake assist goes out and it's very difficult to steer and break the car, I have nearly avoided several accidents, there is no warning that this will occur once I have attempted to safely pull over the car says engine not available, propulsion power reduced, the car will not turn off and it says waiting to initialize on the screen. I have had it towed to my local Chevrolet dealership and paid a diagnostic, they have been unable to determine the cause of the problem and they just reset the car by unplugging the battery and tell me that they cannot replicate the issue. This does not happen while the car is driving on his hybrid battery, it only happens when driving in hybrid mode with the gas motor. In doing my own research, I found a recall campaign that describes the exact issue that has been occurring, it even states that the car may not be safe to drive if this occurs. Recall #18v397000. Each time I towed my chevy Volt to the dealer it sat there for several weeks to a month, they returned it to me and the next day it died in the road. The car is not safe to drive, the dealer states that they can't diagnose the problem and I fear for my life every time I drive the car because it happens at random.

9 Engine And Engine Cooling problem

Failure Date: 11/10/2018

11/10/2018 while driving about 45mph heading school the car totally shut down for not reason, and would not restart. The ev mode shut down and the gas engine did not start. Police recommend to get it towed to safe location. Onstar records, multiple shut down of computer modules. 11.

10 Engine And Engine Cooling problem

Failure Date: 11/01/2018

Vehicle over-revs in cold weather. Engine runs excessively fast (4250 rpm) at highway speeds and around 3000 rpm when just sitting. Often times if I pull over and restart the car it will correct itself. This results in mpg as low as 22. The internet is full of examples of people with the exact same problem. I have seen no examples of the problem being solved. The engine will operate correctly in warmer weather (above 50° f). I believe it is related to an aging propulsion battery and could be solved by improved programing to accommodate the battery state.

11 Engine And Engine Cooling problem

Failure Date: 05/31/2016

I have owned the vehicle for 4. 5 years. In the last two months the error message "propulsion power reduced" has happened and the vehicle has gone into lip mode. All three times the message occurred when the vehicle was started, battery depleted, and gas engine running. Drivabilty was an issue as the car was in limp mode and would not accelerate properly. My car was taken to the dealer, twice. I was told by jay townsend, district manager aftersales Chevrolet, that this is normal operation and he pointed to a bulletin. He said there is no fix, but that going into limp mode spontaneously was a " vehicle characteristic ". It is illogical that an error message popping up is normal "vehicle characteristics" and that going into limp mode is normal. This is a big problem that gm seems willing to accept. Obviously some parameters being broken is setting off the warning message, but gm doesn't want to address this. Instead they are stating it is normal operation. Someone is going to be hurt because of sudden reduction of power and gm's deliberate denial to fix the problem. I don't want this to be me or my family.

12 Engine And Engine Cooling problem

Failure Date: 05/09/2014

When I turned on the vehicle the touchpad showed no a/c. I started to drive the vehicle and approximately 5 miles the heater came on and blew hot air, then after awhile the a/c came on. After accelerating from a stop when I reached approximately 45 mph the vehilce lost power and the sterring wheel locked up. I could not control the vehicle. Then the vehicle jolted and the power returned. This has happened prior and was taken into chevy dealerhip for repair. Loosing power and steering capability is not safe.

13 Engine And Engine Cooling problem

Failure Date: 02/03/2014

While I was driving home my car would surge then lose power. I pressed the onstar button and a vehicle test was conducted. I was told the transmission needed attention. Also, the vehicle lost power while driving and I had to pull off the road. I was on a rural road so no one else was affected. Had I been on the interstate this could have affected others and myself in a negative way. I took the vehicle in and jessup auto in catherdral city, CA kept it several days and corrected the issue. The main issue is losing power while driving.
