Battery Propulsion System problems of the 2012 Chevrolet Volt

2012 Chevrolet Volt, the vehicle has been losing power for propulsion on the highway/roads at all speeds. Shutting off. Electric charge is supposed to switch to the gasoline motor when it is low, but it does not, and vice versa. It shows hybrid battery management has a loss of propulsion with a message of low propulsion power. The original problem was not fixed with a recall a few years back because the same problem is showing up. Now, chevy does not have this VIN being recalled. But worse, the conditions in the software are causing a powertrain failure while driving. Please help. I am pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Temperature sensors responsible for monitoring the battery pack fail unexpectedly. Sometimes displaying a "battery too cold plug into warm" message or a check engine light. Personally, this is the second time I've had a sensor fail. The entire module containing the failed sensor must be replaced. The battery is made up of three different sections called modules. When a sensor fails, the car will simply refuse to start despite being within a normal operating temperature range. I've had the message display when in motion. This time however, the message was accompanied by a check engine light, and a burning odor that resembles burning plastic while the engine is running. I have yet to experience reduced propulsion of any kind while driving.

The issue is caused by a previous software update to the vehicle interface control module (vicm) which was installed to improve the car, but which may have disabled the cell balancing function, causing the Volt to enter a low-voltage condition. This puts the affected Volts into a situation where it would enter what is called a low-power "limp-home" mode, before shutting down completely cause the Volt to shut down in traffic. Dealer states that needs to replace battery which it cost about 6000. Chevrolet is not responding for the defective problem that caused the recall. Low-voltage battery cell issue or propulsion reduce.

Tl the contact owns a 2012 Chevrolet Volt. The contact stated that while driving at 60 mph, the reduced propulsion error message was displayed on the instrument panel. The engine revved up and the vehicle stalled without warning. The contact pulled over and restarted the vehicle however, the vehicle failed to accelerate. The vehicle was towed to beaty Chevrolet (9615 parkside dr, knoxville, TN 37922) where he was informed that the Voltage on the battery was low and needed to be replaced. The contact spoke to serra Chevrolet Cadillac Buick GMC kia (189 stonebridge blvd, jackson, TN 38305) where the dealer discussed trading in the vehicle, but offered no assistance for the repair. The manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was 162,000.

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.

The car will shut itself off with very little time to get to the side of the road if that is even a possibility. When switching from battery power to the gas motor. Randomly. The car will die at any speed. First message is low propulsion power. Next message engine not available, service soon. Less than 4 minutes from 1st message to total shut down. Least amount of time between messages and shut down is 15 seconds. Car will decelerate (on highway where vehicles behind have no warning. . . No brake lights that car is rapidly losing speed). Never know when it will happen. Usually car will restart and run terrible. . After 20 minutes or so. After restart car runs bad low power. Check engine light is on. After 10 more minutes of driving. It straightens out. Usually. Dealership unable to find problem. Assorted codes in computer. Very dangerous when driving. Especially when it happens and it is 15 seconds to complete shut down. I have opened a case with Chevrolet. No response as of yet. They were supposed to call within 2 days. I will upload an attempt at restart as it is the only one I have where I was safely in a parking lot when it happened. Usually I am not. And many roads in my area do not have a shoulder.

I was driving in 50 mph traffic it lost all propulsion. The problem I have sounds exactly like the problem gm has issued a recall for with 2013-2015 Volts. I believe gm did or should have anticipated the problem and did nothing. Gm program n172130462 has owners of 2013-2015 Volts bringing their cars in to dealerships for a software update. Gm has recognized that these cars "may have a condition where it could gradually lose the ability to maintain Voltage. If battery concerns are not addressed, over time the vehicle could enter a reduced propulsion mode while driving, or lose propulsion, or it may not start. " I brought my Volt in to the dealership on January 31, 2019, because it was not consistently holding the charge that it normally did and the car would often start in "low propulsion mode" when starting it after turning it off with the battery low or depleted. Despite being under warranty the dealership, bob steele Chevrolet in cocoa, FL, claimed the could not figure out what was causing the problem, refused to try further, and sent me on my way with a bill for their failed efforts. On July 19, 2019, I was driving in on my way to work in my 2012 Volt with 101,400 miles. The car switched from battery to gas as it had many times before. About one mile later it switched back to battery, gave a message that it was going into "low propulsion mode", and stopped providing any propulsion. This occurred while I was on us1 and it was dangerous for me to rapidly change lanes while losing speed to get off the road. I got to a parking lot without enough speed to get up the mild incline at the entrance and was stuck blocking the entrance while I awaited a tow truck. This loss of propulsion could have happened at any speed and things would have been worse had I been on the interstate.

While driving sudden loss of power having to basically depress gas pedal to maintain speed while simultaneously receiving "reduced propulsion error". Dealer cleared error and did a reprogram. After picking up vehicle range was reduced approximately 1/3rd but car ran. Shame on me for not being more forceful about range reduction because this battery was defective. This summer June 2020 complained about reduced range and dealer did more programing. Now in October 2020 reduced propulsion error came back and hybrid battery is bad. Warranty ran out in may 2020 and gm refusing to acknowledge 2018 date of defective battery.
