Electrical System Problems of Chevrolet Volt - part 1

Chevrolet is denying that my car is included in special coverage bulletin n232432680, because of where it was built. The car is now in kentucky, which is not a carb state. Was the reason for a vehicle not to be included in the bulletin because it would be included under carb? it seems like a loophole they are using not to fix my car. Am I wrong?.

While driving on a highway the car started to hesitate, a message appeared on the console "propulsion power is reduced" and the engine light turn on. After driving some miles, a new message appeared: "engine unavailable, service soon" and the car only ran on electric power, no motor engine. I had the same problem 3 year ago and the dealer identified the problem as a shorted egr valve. This time I knew this shorted egr valve burns the f3 fuse. I managed to get to a car part shop and bough several fuses (15 amp). After replacing the fuse 3 times I managed to get to the dealer. The repairs cost $3000+ (up from $1000+ 3 years ago). This problem is well documented on the gm service technical bulletin "21-na-116" dated February, 2023. Three years ago I was in the middle of nowhere in south texas and it took 6 hours to get a tow truck this time I was lucky enough to be close to to a town that the remain battery power was enough to get to the store where I bought the fuses. Gm should recall this part and do a proper fix.

The vehicle had a the becm fail at 64,000 miles. This is a known issue that gm still refuses to recall, and is refusing to warranty.

The battery energy control module (becm) failed. Before repair, the check-engine light appeared intermittently, the vehicle sometimes had difficulty starting, and the indicated electric range could suddenly drop from about 30 miles to zero despite a charged high-voltage battery. When this occurred, the gasoline engine started unexpectedly. The air conditioning also intermittently blew warm air until the vehicle was restarted. These symptoms created a safety concern because propulsion mode and indicated range could change without warning, and the vehicle could fail to start in traffic or another unsafe location. An authorized Chevrolet dealer confirmed the problem. The dealer retrieved dtcs u2624 and u2629, performed circuit testing, and diagnosed an internal short in the becm causing loss of communication with high-voltage battery modules. The dealer stated this failure caused the warning light, starting issue, sudden loss of indicated battery range, and air-conditioning symptoms. The becm was replaced and programmed after removal of the high-voltage battery assembly. The warning light first appeared about one month before repair, with the other symptoms becoming more apparent in early July 2026. The vehicle had approximately 80,918 miles when inspected. The failed component was retained by the dealership as a core and is not available to me for inspection. To my knowledge, the vehicle was not separately inspected by police, insurance, or gm engineering personnel. My vehicle was excluded from gm special coverage n232432680 even though it is a 2018 Chevrolet Volt with the same confirmed becm failure addressed by that program and NHTSA investigation pe23022. I paid $3,970. 56 for the repair. I am filing this complaint because this defect can cause no-start, loss of indicated battery range, warning lights, unexpected propulsion changes, and potentially reduced propulsion, while some affected 2016–2018 vehicles appear excluded from the special coverage.

While driving at highway speeds over 100 miles away from home with my child in the vehicle, the car experienced a sudden, catastrophic loss of propulsion power and entered 'propulsion power reduced' mode, dropping vehicle speed immediately and creating an extreme hazard with high-speed highway traffic. A full computer scan revealed active diagnostic codes u2603 through u2624, confirming an internal hardware communication failure of the battery energy control module (becm). This matches gm technical service bulletin 18-na-261. The vehicle has over 150,000 miles, but I have only owned the car since January. This is a known, systemic manufacturing defect (cracked internal circuit board solder joints) that creates a critical safety liability regardless of vehicle mileage. Gm has refused to remedy the safety defect due to the mileage limit.

I purchased the above-listed 2016 Chevrolet Volt through carvana, relying on the contractual promise that the becm was covered under special coverage n232432680 for up to 15yrs or 150k miles. The vehicle has suffered persistent, severe mechanical and electrical issues resulting in a prolonged loss of use: 1. Initial breakdown and delivery: the vehicle originally had a reduced propulsion power alert on Monday [xxx] around 8pm and nearly caused me to be rear ended on a major road due to accelration issues. It then officially broke down on Tuesday, [xxx]. It was then delivered to vic koenig Chevrolet (1040 e main st, carbondale, IL 62901) via tow by freedom towing the following Friday, may 29, 2026. 2. Delayed work start & shop stay: vic koenig Chevrolet was able to officially begin diagnostic and repair work on Wednesday, June 3, 2026. The facility held the vehicle for several weeks to address the failures. 3. Brief release and immediate re-breakdown: I picked up the vehicle upon its supposed completion on Tuesday, June 16, 2026. Then less than 24 hours later, on Wednesday, [xxx], the vehicle suffered a recurring breakdown and had to be returned to the dealership immediately. 4. Wrongful coverage denials: on Thursday June 19, 2026, silver rock claims representatives issued explicit coverage denials to me via text message. That same day, service representatives from vic koenig Chevrolet phoned silver rock multiple times to provide diagnostic evidence, but silverrock repeatedly issued oral denials over the phone. They stated the pcm and becm were not included in the contract, screenshots of the vontract state the opposite. Silverrock sent this refusal via email to me on June 19. I also contacted gm by phone on Wednesday 5/27/26 and so did the dealership and they refused to cover my vehicle under the special warranty for the known issue. I tried to request a cost reduction and they denied it again on 6/22/26. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle (2018 Chevrolet Volt) is experiencing an intermittent failure of the battery energy control module (becm). Diagnostic trouble code p1e5b was stored in the system. This is a well-documented defect in this vehicle population that frequently results in a sudden, unexpected loss of propulsion power while driving ("propulsion power reduced" mode), posing a significant safety risk in high-speed traffic. ?although a Chevrolet dealership confirmed the presence of the stored fault code, they refused to perform the repair under the extended warranty (special coverage n23243268) because the check engine light was not actively illuminated at the exact time of inspection. The manufacturer requires the vehicle to be operated until the fault recurs, exposing the driver and others to the danger of stalling on highways or at busy intersections. The failed component remains in the vehicle and is available for inspection.

Fully charged. Goes from electric to generator/gas propulsion and abruptly slowes about 1/2 speed. Very dangerous.

Becm failure. My car is available for inspection upon request. This car has unexpectedly stopped adequately accelerating all of a sudden while on the road! this problems has been confirmed by the dealership. The manufacturer has not inspected it. Not much warning. I found out some not all Chevrolet Volt 2017 users got their becm replaced without cost because it is a well known issue with the car. Chevrolet did not provide extended warranty for all Chevrolet Volt users even though it is an issue with most Volts. I do drive much. I got the car when it was brand new and in 8 years accumulated 77k miles. If I had known all of the cars would have had this safety issue I would not have bought the car in the first place. Chevrolet expects me to pay 2500 out of pocket for something they know is faulty and dangerous in their vehicles.

The car suddenly lost power and produced error messages on the screen. I had to quickly change lanes to get out of traffic on the highway. My dealer diagnosed the issue as a becm malfunction and quoted a repair cost of approximately $3500. However, due to my car originally being registered in California, this failure is not covered under gm special coverage bulletin n232432680 (issued March 2024), which provides an extended warranty for becm issues on affected 2016-2018 Volts up to 15 years or 150,000 miles. My VIN does not qualify for this coverage despite the vehicle being within the model years affected by known becm soldering/connection failures. This appears to be part of a broader pattern of becm defects in 2016-2019 Volts that can lead to sudden loss of propulsion, as previously investigated by NHTSA. Gm should extend coverage or issue a recall for all affected vehicles, as this defect compromises vehicle safety and leaves owners with expensive out-of-pocket repairs for a known issue.

I have a 2016 chevy Volt. It had to be towed to a chevy dealership because it will not drive. The becm module has failed, as is apparently the case with so many Volt owners. Gm, as a result of lawsuits about this car, extended the warrantee to fix the issue, but my VIN number is not included in the case. The gar is a brick, and there is no way to fix it now. Gm doen't even replace these batteries any more, and most often just buys back the bad vehicles. I still owe 9k on this car and it is useless now. I need help. These are the codes is is throwing. B101d p1eoo p1eac poafa b3111 u3001 u2401 u2603 u2604 u2605 u2606 u2617 u2618 u2619 u2620 u2621 u2622 u2623 u2624 p1fd1 p1fd2 p1fd3 p1fd4.

In March 2026, our 2017 Chevrolet Volt (89,300 miles) would not charge nor start, and had to be towed to an authorized Chevrolet dealership in portland, oregon. The dealership diagnosed an internal fault in the battery energy control module (becm) producing u26xx diagnostic trouble codes, per gm bulletin #18-na-261, and replaced the becm under gm special coverage n232432680 — gm's field remedy for a known becm defect affecting 2016–2019 Volts that causes reduced power, no-start, or no-charge conditions (the subject of NHTSA investigation pe23022). The remedy failed immediately. On the day the vehicle was returned to us (March 26, 2026), the check engine light illuminated while driving home on public roads, and the vehicle failed to charge that same night — the identical condition it had before. It was towed back to the dealership. The dealership's second work order confirms in writing that the vehicle "will not start after previous repairs and is having the same issues," and attributes the failure to the high-voltage battery contactor. The dealership informed us the part is no longer produced and cannot be obtained, advising that the vehicle be scrapped. Safety concerns: (1) after the repair, the dealership returned the vehicle to us as fixed, and we drove it approximately 26 miles home on public highways in traffic, unaware the defect was still present — the check engine light illuminated during that drive. This defect is the subject of NHTSA investigation pe23022 into sudden loss of propulsion, we unknowingly operated a defective vehicle in conditions where that failure could have occurred at highway speed; (2) gm's official field remedy for this known defect (special coverage n232432680) failed within hours of being performed; and (3) the parts required to complete the remedy are reportedly discontinued, leaving a known safety defect permanently unrepairable. Supporting documents uploaded: dealer repair orders, and the gm warranty history of the n232432680 repair.

Failure of battery energy control module (becm), within the high Voltage battery. Vehicle is unable to charge and sets “reduced power” message. Gm released special coverage bulletin for this issue (n232432680), but this vehicle is not listed due to which state it was registered. Continued failure of the becm will lead to inoperability of the vehicle.

I am reporting a series of safety concerns regarding my 2017 chevy Volt, which have persisted despite multiple attempts to address them with the dealership. These issues pose significant risks to my safety and that of others on the road. On January 18th, 2024, I brought my vehicle to the dealer after experiencing reduced propulsion power while driving on the highway, coupled with the illumination of the check engine light. The mechanic performed a quick inspection and used a gm scan tool to diagnose the issue, revealing the code p1e00 for the hybrid powertrain control module 2, which was cleared without a thorough investigation. I was advised to return if the issue reoccurred. Despite the reset, the problem persisted, and on February 9th, 2024, I scheduled another appointment due to my chevy Volt's high Voltage battery charging only to 65% capacity despite indicating a full charge. Subsequently, on February 11th, 2024, the check engine light illuminated again, and on February 12th, 2024, November 25th, 2025, January 11th, 2026, and February 12, 2026 while driving to work, both times I experienced a loss of propulsion power on the highway, placing my safety at risk and lost all power in a traveling lane of traffic. These ongoing issues with propulsion power and the high-voltage battery charging system are not only inconvenient but also potentially dangerous. Despite multiple visits to the dealership and attempts to diagnose and resolve the problem, it persists, indicating a systemic issue that requires immediate attention. The reduced propulsion power while driving on the highway, coupled with the illumination, I urge the national highway traffic safety administration (NHTSA) to investigate this matter thoroughly to ensure the safety of chevy Volt drivers and passengers. It is imperative that general motors addresses these issues promptly and implements appropriate measures to prevent further incidents.

Three separate high-voltage battery section failures within one year, each causing complete loss of propulsion. Two occurred at freeway speeds on [xxx]. Failure 1 ([xxx]): vehicle lost propulsion. Dealer diagnosed dtc p0afa (low Voltage), failed cell in battery section 3. Section 3 replaced under gm special coverage n232432680 (becm, 15yr/150k). Vehicle out of service approximately six months awaiting gm authorization and parts. Failure 2 ([xxx]): vehicle lost propulsion on [xxx] at night at freeway speeds. Required towing. Dealer diagnosed dtc p0afa, cell 85 at 1. 85v in battery section 1 (different section). Section 1 replaced under same special coverage. Vehicle returned Jan 28, 2026. Failure 3 ([xxx], ~300 miles after failure 2 repair): vehicle again lost propulsion on the freeway with check engine light, then progressed to no-start condition. Towed to dealer. Diagnosed Feb 20, 2026: dtc p0afa, cell 57 at 1. 5v in battery section 2 (gm minimum spec 2. 5v). Third distinct section failure. Vehicle remains at dealer awaiting gm repair authorization as of filing date. Safety concern: loss of propulsion at freeway speeds is an immediate safety hazard. During the Nov 2025 event, the vehicle lost power on [xxx] at night in active traffic. The progressive failure pattern (three different sections failing sequentially in the same pack, identical dtc) suggests a systemic defect rather than isolated component failures. Prior section replacements have not resolved the underlying problem. Vehicle has been usable approximately 20 total days in the past 12 months. All repairs performed or pending under gm special coverage n232432680. Gm case [xxx]. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I received the "propulsion power is reduced" alert engine light while driving in "normal" mode on the freeway at around 60mph with 8-9 miles of battery capacity, it showed 0 miles of battery forcing the gas engine on and the vehicle hesitated upon applying the accelerator for the remainder of the drive. My safety and that was others was at risk because the acceleration dropped quickly and I was on a busy freeway at the time when the alert happened causing further hesitation. Upon stopping I could not get the vehicle to take a charge nor would it start up until a mechanic arrived and was able to confirm the problem.

There is a ongoing problem with the becm on 2016-2018 Volts. Mine is one of them. Contacted Chevrolet and they say my VIN isn’t under the extended coverage. I believe it should be and can’t stand they won’t cover my car under warranty. Is there anything you can do?.

The contact owns a 2012 Chevrolet Volt. The contact stated that the vehicle failed to start, and the lights inside and outside of the vehicle failed to illuminate. The vehicle was jump-started. The failure reoccurred while attempting to restart the vehicle, and the contact was unable to drive the vehicle. The vehicle was not taken to the dealer to be diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was unknown.

While I driving in the past week, a warning that "propulsion power reduced" appeared on my dashboard several times. The last time that I had driven the car, the heater would not turn off, and the smell of burnt rubber filled the car and then dissipated soon after. The car would only run in it's gas engine mode, and not switch over to electric mode, as it usually would. The next morning, the car would not start. The dash board would light up as if the car started, but when I shifted into drive, a warning appeared on the dash, "shift to park", as it would when the car is not running. I could not start the vehicle. After plugging the vehicle in, a warning appeared on the console stating that "charging is not available". The car was towed to the dealership. Their diagnosis showed that the battery energy control module had failed and must be replaced. They later confirmed that an electric cable needed to be replaced that was "corroded", but they could not confirm the cause of the corrosion because the cable was disposed of already. After researching online, I found that gm issued a special coverage bulletin: n232432680, citing a common malfunction of the battery energy control module in 2016 to 2018 chevy Volts that "causes a reduced power mode, a no start condition, or a no charge condition. " the special coverage was to extend the warranty to 15 years or 150,000 miles. After inquiring the dealer about the special coverage, they claimed that our car is not covered under the warranty. After calling customer service, they claimed the coverage comes from NHTSA, and gm only issues orders by VIN, and therefore cannot cover the issue. After calling NHTSA, I was told the special coverage is not a national recall, and is internal to gm. The gm dealership still claims that the control module on our car is not covered under the warranty, and have denied the request for a manager inspection or investigation.

Following a day trip involving sub-freezing temperatures and full depletion of the traction battery, the vehicle was plugged in at home and appeared to be charging. The following morning, I enable the preheat via the remote before leaving the house for work, and notice the cel/mil before starting the car. Car was cold, charging indicator was flashing green as if it was accepting charge. I went to investigate and was met with the following list of codes: p1e00, u2603, u2604-u2606, u2617-u2624, p1fd2, p1fd3, p3042, c326c, p0096. Car turns on but seems to only be accessories; no power steering. Seems like the state of charge indication kept transitioning from empty to full. I unplugged the car to see if it could still drive, but no luck. Getting "shift to park" when I put it in drive. Switching to hold does not engage the engine. After plugging it in again, the car no longer receives charge and simply holds the orange charge indicator light. In an attempt to get the car into limp mode, I tried clearing the codes, but no luck. After reading the codes again in the afternoon, the following codes posted: p1e00, u2622, u2623, p1fd4, p0afa. These codes and behavior are consistent with the following ntsb service documents, which call for the replacement of the becm: special coverage n232432680 technical service bulletin 18-na-261 however, the vehicle in question does not appear to be one of the 19,000 vehicles covered under the special coverage, per gm’s warranty look-up. The vehicle has not yet been serviced for the above events, but it is assumed the becm is failing, which is available for inspection. My safety was not put at risk this time, but it is possible for the becm to fail in an unsafe manner. Additionally, the associated repairs are costly since the becm is not easily accessible, requiring lifting the car and removing the entire traction battery.

The contact owns a 2016 Chevrolet Volt. The contact stated that while driving at an undisclosed speed and making a left turn, the vehicle stalled. The accelerator pedal was released, and the vehicle returned to normal operation. No warning light was illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact related the failure to NHTSA action number: pe23022 (electrical system) and special coverage: n232432680 (battery energy control module malfunction); however, the vehicle was not covered under the special coverage. The manufacturer was made aware of the failure. The failure mileage was approximately 71,000.

My 2017 chevy Volt stalled, wont charge, safely concerns. Safety-related special coverage is being denied by local chevy dealer. Check engine light codes u2603-06, u2623, well known issue in chevy Volt community, that points to chevy faulty becm. Chevy replace these to some selected 2016-2018 vehicles, but they wont cover mine, while I have same exact issue. Please help to push on chevy to cover all 2016-2018 chevy Volt by recalls repairs with no cost to owner. Thanks.

Battery energy control module malfunction. It is a known issue with this system failing on the chevy Volt. There is a service bulletin on this problem. 18-na-261 is the service bulletin. The car will not start and when it does start it has loss of power while driving. Chevy is only fixing certain VIN numbers even thou it pulls up the same codes in their bulletin. Chevy only gave extended warranties to certain VIN numbers also. Extra warranty bulletin n232432680. This is a major component for the high Voltage battery which drives the vehicle. The dealership wants $5000. 00 to repair this.

The becm (battery energy control module) failed. The vehicle illuminated the mil and the driver display to show a "reduced power". When restarted, the display showed "shift to park", which I did several times. After a couple of restarts it displayed the "reduced power" message, but would not go into drive. The mil was illuminated the entire time. Through numerous key cycles I got the VIN operable and took it to the dealer for repair. The becm part is at the dealer or on its way back to gm as a core return. While this occurred while I was leaving my garage, it could have occurred in traffic, which would put me or others at risk. The problem was investigated by my local dealer (currie Chevrolet in forest park, IL) and it was determined to be both a bad battery energy control module (becm) and a bad shifter assembly. The shifter had been replaced (or repaired?) for an earlier shift to park failure per TSB 23-na-119. The dealer kept the becm as a core. I have pictures of the core. The dealer or gm should have that core. The above described warning lamps and messages and systems first appeared at the time of the event that lead me to take it other dealer ASAP. Note the condition and model year is described in gm special coverage letter "n232432680 battery energy control module malfunction". Nhtsa investigation pe23022 lead to this coverage letter. Per gm, while my vehicle experienced the conditions and is in the model year coverage of the letter, its VIN is not covered. I think NHTSA should re-open the investigation and consider a recall. There could be other vins susceptible this failure condition. There could be operators of those vins who cannot afford the expense (~$3000 or more) or downtime of the repair, and will keep operating the vehicle, putting people at risk again. If a recall is not supportable, I'd request that the VIN list be expanded to cover all possible defective becms.

The contact owns a 2018 Chevrolet Volt. The contact stated that the battery module became inoperable. While attempting to start the vehicle, the message "engine unavailable - service soon” was displayed. The contact was unable to use the vehicle. The contact stated that the tpms warning light was illuminated. The contact associated the failure with technical service bulletin: 18-na-261. The contact called the local dealer and was referred to the manufacturer for assistance. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed that the VIN was not under recall. The failure mileage was approximately 111,000.

The engine light starts blinking and telling me propulsion power reduced, and then I cannot use the cruise control after that turns on, and it starts losing power, driving on I 70 after work all of a sudden it turned on and wet from going 76 miles an hour to 52 on highway I 70 where the speed limit was 75. This problem was a recall problem which was fixed and now is happening again on the same part and having the same problems.

The contact owns a 2017 Chevrolet Volt d2. The contact stated that while attempting to turn the vehicle on the vehicle did not start. The contact stated that vehicle restarted after an hour. The contact stated the during the second occasion the vehicle did not restart. The vehicle was towed to a dealer where it was diagnosed that the battery energy control module needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure. The failure mileage was approximately 75,000.

The contact owns a 2018 Chevrolet Volt. The contact stated that while attempting to start the vehicle, the engine failed to turn over as intended. Additionally, the vehicle would not charge when connected to a charger. The check engine warning light illuminated. The vehicle was taken to a local dealer, where the becm was reset. The vehicle was repaired; however, the check engine warning light remained illuminated. In addition, the contact stated that the message "reduced power" was displayed on the instrument panel. The vehicle was taken back to the same local dealer where it was diagnosed, and determined that the becm needed to be replaced. The vehicle was not repaired due to the cost. The contact related the failure to an unknown Chevrolet recall; however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 129,000.

The high-voltage heater control module (also known as the ptc coolant heater / k10 heater module) has failed. This component controls cabin heat and windshield defrost when the vehicle operates in electric mode. The authorized Chevrolet dealer diagnosed the issue, confirmed the failure, and attempted to order the correct gm part. Gm informed the dealer that the part is no longer manufactured or available through gm channels. As a result, there is currently no gm-approved repair path. This failure prevents the vehicle from providing windshield defrost while operating in ev mode, which is required for safe winter visibility. I live in new hampshire, where winter temperatures routinely require functioning cabin heat and defrost for safe operation and compliance with state visibility laws. Because this is a high-voltage thermal management component, there is no safe aftermarket repair option. The inability to obtain an oem replacement part for a safety-related system prevents the vehicle from operating safely in intended ev mode.

The becm failed, engine light on, car is at reduced power or doesn't run at all. A message states that there are no ev miles available when it is full to to place the shifter into park. There is a free extended warranty for it (xxx- special coverage--battery energy control module malfunction - ) but my Chevrolet dealership in wenatchee, washington says that it's not covered. I want to know why they said this. I have been stranded without an operable car, unable to get to and from work. If I don't go to work, I can't pay my mortgage. I don't have another car to drive or the means to rent one. It needs to be towed 90 miles to a dealership which that price will be astronomical on my poverty level income. I have cancer and need to get to my treatments. The cost to replace the becm is $2100-$3000 out of pocket not including towing. The error code was read as a failed becm by a diagnostic reader and it's having all the symptoms of a failed becm. It has the following code: p1e00 $07e8pd initial symptoms in the prior week before the car wouldn't operate, was that I got a message to put the car into park when it was already in park. Sometimes the display wouldn't work. Sometimes the heater wouldn't turn on in the preceding 2 months. Global safety field investigations dcs6812 urgent - distribute immediately reads that 2016-2018 Chevrolet Volt models are covered. I've attached this letter.

On 10/14, I was driving the car to my job, when the car suddenly switched from its electric battery power to its internal combustion engine. The vehicle's information screen only showed that the battery was unavailable. I was able to operate the car on only the internal combustion engine to arrive at work. However, when I went to leave several hours later, the car would not start. The car was towed to a dealership and apparently repaired after about a week. However, the repair, a software reset, did not fixt the underlying issues, and on 10/27, after having the car for five days, the car again failed on my way to work, displaying a "shift to park" message and not starting. I towed the car to the same dealership, and they had it until 11/04. I recovered my car and drove it again to work that same day, but the car failed again due to the dealership not correctly diagnosing the issue, which appears to be the becm, a failure related to bulletin n232432680. Due to this issue, I was left stranded on a busy highway for several hours on multiple occasions, and have not have a working vehicle since 10/14, meaning I have had to call off of work on multiple days, losing non-trivial amounts of income and undue economic hardship, due to this issue. Neither the dealership nor general motors have offered any kind of help or support, and have generally attempted to avoid responding to my repeated phonecalls. Prior to this issue, there were no warnings or symptoms that I observed.

The passenger presence sensor is failing or failed because every time someone sit in there the airbag turns on and off repeatedly every 2-3 mins and gives a service airbag warning and if no one is sitting in the passenger seat then it just stays on. Could be really dangerous if a wreck happens while it’s glitching in the off mode and could cause death. Multiple people have had this problem with the Volts and there is even a thing you can by to completely bypass the airbag going off which shows how common the problem is if there is a solution to eliminate it in an unsafe/not factory manner.

The car can't decide if it wants to use the battery or the engine. It shows zero charge even though it is full. It lurches at stop lights as it tries to decide whether to use battery or engine. It says "propulsion power reduced". "not able to charge". "shift to park". Check engine light is on.

Dashboard displays “shift to park” message even when the shifter is in the park position for the past month. I am unable to turn off the vehicle completely until I shift to drive then back to park multiple times.
