2016 CHEVROLET VOLT Complaints

The car states the battery will not charge and cannot move the car. I connected it to a code reader with the following codes showing: P1E00 U2618 U2606 U2605 U2617 U2604

No propulsion with U2603 through U2618 DTC in HPCM2 with "shift to park" message. BECM was replaced by dealership.

GM issued a special coverage warranty for 2016-2018 Chevrolet Volts that had a BECM failure. However, they did not include all of the Volts. We have a 2016 that has a catastrophic BECM failure. The car won't start and the only indicator was the day before it said the vehicle didn't charge. This appears to be the same issue, but Chevrolet did not include our model. We have about 87k miles and are only 3 weeks past the original warranty.

The EGR valve failed part way through a long drive between cities while at interstate speeds. This caused the vehicle to produce a warning about reduced propulsion power (as well turn on the check engine light), and it became difficult to maintain speed with the surrounding traffic. I could maintain speed, but only in electric-mode, and my battery didn’t have enough energy to get me to my destination on that power alone. While in ICE mode (internal combustion engine mode) it would also quickly overheat. I reached my destination by repeatedly swapping between ICE and battery modes, to both extend my vehicle’s range as well as mitigate overheating. Upon arrival at a dealership, I was informed there’s a nation-wide shortage of EGR valves for my model of car. Despite escalating the issue with GM/Chevy’s support staff, they cannot locate an available EGR valve. This shortage has lasted for more than 4 months now and my car remains stuck in a distant city. This part is necessary to operate the vehicle safely, but they have not been producing enough of the part.

This vehicle has been intermittently displaying shift to park, reduced propulsion and loss of power. Chevrolet will not address its problems utilizing the March 6, 2024 service bulletin that covers this model year despite it exhibiting these dangerous warnings and reduced power and stoppage. Please help!

EGR valve failure. No replacement parts being made to replace failure. Engine doesn’t run smoothly and check engine light is on. Items been back ordered since August last year. No longer California compliant, cannot pass smog. Danger hazard.

The contact owns a 2016 Chevrolet Volt. The contact stated while driving 40 MPH, the battery was fully charged; however, the mileage range went to 0. The contact stated that the fuel system engaged, and he drove to the dealer, where it was diagnosed that the electronic control module (ECM) had failed and needed to be replaced. The contact related the failure to GM Campaign Number: N232432680; however, the dealer informed the contact that the vehicle was not covered. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that they could not assist because the vehicle had a Salvage Title. The failure mileage was approximately 44,000.

Chevy has put out a "special coverage" (number XXX) on 2016 to 2018 volts on the BECM issue that is currently being investigated. I need to make the note that upon trying to fulfill this warranty/ special coverage on my 2016 volt, they are finding loopholes to not cover a huge handful of 2016 to 2018 volts that have the exact same BECM issue and components as the volts that are covered. Although I'm not positive, it seems to me that they are not granting special coverage to all volts that have a PZEV warranty in place as it's redundant. However, 75% of us with PZEV warranties are in non CARB states and cannot utilize the warranty. So they are leaving us within this category who have the exact same BECM issues as every other 2016 to 2018 volt out of being eligible for the new coverage, while making it look like they are fixing the entire issue. They are secretly leaving a handful of us dry and without this coverage. Not only that, they are refusing/ unable to give me accurate information as to what vehicles qualify for this warranty if not all 2016 volts which is against the Magnuson-Moss warranty act and illegal on their part. They forced me to pay $2500 for this repair after telling me I would be covered by warranty and obviously would have held my car had I not paid. After telling me it was free. Somebody needs to probe deeper into this and make sure that Chevy is honoring what they claim because it appears to me they are secretly trying to [XXX] a percentage of 16 to 18 volt owners who have the exact same issues and components as the cars that are covered. This is a safety issue as my car died and temporarily stranded me several times before this repair as you guys already know is an issue with the 16 volts that Chevy has refused to acknowledge until recently.

I got the “propulsion power is reduced” warning at ~83.5k miles on the odometer, while visiting friends 4 hours from home. Pulled over and called 3 local dealerships and all servicing departments are closed on Sunday so knew there was nothing I could do except try to limp back to my friends house safely and reevaluate. On the 20 minute drive back, the engine cut out on the freeway and the car immediately started slowing down. I coasted to the next freeway exit safely with my hazards on. The scary part was that I had no power after the ”engine unavailable” warning popped up since the battery was completely drained already. I was able to get it towed to the closest chevy dealership and leave the keys for them. I am waiting to hear the official diagnosis from the dealership once they take a look. The cause is still unknown but this sounds like a similar series of events for BECM failure.

The contact's son owns a 2016 Chevrolet Volt. The contact stated that the vehicle was taken to the dealer due to an oil leak caused by a puncture in the oil filter. The vehicle was repaired. The contact's son had informed the dealer that he had been smelling a fuel odor inside the vehicle; however, the dealer informed the contact's son that the odor was probably a burning oil odor. The vehicle was taken to an independent mechanic, where it was diagnosed that the fuel rail was leaking and needed to be replaced. The mechanic contacted the dealer who informed him that the part was on a national backorder. The mechanic replaced the part with a used part; however, the failure persisted. The dealer was notified of the failure and informed the contact that the part was on backorder. The vehicle was not repaired. The manufacturer was notified of the failure and offered a coupon towards the purchase of a new vehicle. The failure mileage was approximately 60,000. The contact stated the Volt engine starts periodically even if it has battery power available. The engine forces itself on and can not be turned off manually.
