Owners have filed 48 complaints
about the 2019 Chevrolet Volt with NHTSA between 2018 and 2025.
The largest single group is the transmission & drivetrain.
Across this model's run it ranks 4 of 9 worst.
The letter says how bad. This says what kind — whether this year drew
an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 7
Against the median year of the Chevrolet Volt. 50 means typical for this
model; 100 means roughly double.
Severity — 86
16.7% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.
Early failure — 100
67% of failures with a mileage on record happened under
36,000 miles, against a national rate of
29%.
Odometer readings owners gave when they filed. About half of all
complaints include one.
1,000 – 9,999 miles

When owners complained
A spike years after the car went on sale usually means a part wearing
out on schedule across the whole fleet — the kind of pattern no single
owner can see from inside their own car.

NHTSA investigations into the 2019 Chevrolet Volt
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Recalls on the 2019 Chevrolet Volt
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.

SEAT BELTS:REAR/OTHER
General Motors LLC (GM) is recalling certain 2018-2019 Cadillac CT6, Escalade ESV, Chevrolet Suburban, Volt, and GMC Yukon XL vehicles. Certain second-row or third-row rear seatbelts retractor assemblies may not automatically lock when the seatbelt is fully pulled out of the retractor, possibly preventing a child seat from being properly secured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."
Risk: If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.

General Motors LLC (GM) is recalling certain 2018-2019 Chevrolet Equinox, Impala, Cruze, Volt and Bolt EV vehicles, GMC Terrain vehicles, Buick Lacrosse and Regal vehicles, Cadillac XTS and XTS Professional vehicles and 2018 Chevrolet Malibu vehicles. The rear brake caliper pistons may have an insufficient coating causing gas pockets to form, potentially reducing rear brake performance.
Risk: A reduction of braking performance can increase the risk of a crash.

Recall 2018535780 units in Canada
Seats And Restraints
Certain vehicles may be equipped with rear seat belt retractors that do not comply with the requirements of Canada Motor Vehicle Safety Standard (CMVSS) 208 - Occupant Protection in Frontal Impacts. The automatic-locking retractors (ALR) of the rear seat belts may not switch to a locked position when the seat belt is fully pulled out of the retractor. If used to secure a child seat, a seat belt that is not properly locked could increase the risk of injury to the child in the event of a crash. Correction: Dealers will inspect the rear seat belt retractors and replace them if necessary. Note: If the ALR is not working properly, a child seat should not be installed using the vehicle seat belt until this recall is completed.

I was in stop and go traffic; when the car in front of me stopped suddenly, I tried to brake. I was far enough back that I should have been able to stop in plenty of time. My brake pedal froze and would not depress (brake pump failure). There were no warning light prior. The car has less than 28,000 miles and relatively new tires.

POWER TRAIN
Two incidents related to the powertrain. 1) In December, 2023, the EV battery was drained and the car would not start based on the gas motor. The dealer fixed it in our recollection. 2) On [XXX], I was driving the car out of a Detroit Convention Center parking lot, going up the ramp when the car, with no warning, completely lost power and stopped. The message on the display said "Powertrain loss" or "Powertrain lost." I wish I had taken a photo of it, but I was panicked. Cars were backed up behind me on the ramp out of the parking garage, honking and having to back up. I tried turning the car off and on, googling the problem, and was about to call a tow truck when after 12-13 minutes, I was able to restart the car. I was scared that this could happen again on the freeway. When we could do it together, my husband and I took the car to Chevrolet Suburban of Ann Arbor, which says that they can find nothing wrong with the car, cannot replicate the problem, and that the car computer does not have any error code. They and GM are not willing to do anything to fix it. If they are really unable to find an error code, then something is wrong with the car computer too. I will not drive that car again until it is fixed - I consider it to be risking my life and others' lives to do so. We are spending a lot of money leasing a replacement vehicle as they will not even give us a loaner. The car is just sitting in their lot. And if we trade it in, will they resell it to someone else, potentially putting their lives at risk? - The vehicle is available for inspection at Chevrolet Suburban Ann Arbor. - My safety was at risk. So was that of other drivers around me. I could have been rear-ended. - The problem has not been reproduced/confirmed. - The vehicle and component have not been inspected by the manufacturer, police etc to our knowledge. - There was NO warning ahead of time and no symptoms prior to the problem. The warning message displayed simultaneously with the problem INFORMATION REDACTED PURSUANT TO THE FREEDOM OF IN

STEERING
While driving home one evening, the power steering suddenly failed. A warning message displayed to service the power steering. It became very difficult to steer the car. I had to pull extremely hard on the wheel to be able to make turns. For the turn into my community, I had to make four attempts to get the car to clear the turn through the entrance gate, needing to back up repeatedly and retry. Fortunately I did make it home safely and shut the car down. I made an emergency repair appointment for the next day at a Chevrolet dealership. In the morning the power steering was back. The car was inspected at the dealership. They told me a software update was needed and they charged me $450 to do that.

Vehicle has developed an intermittent issue when placed in park. Displays a message "Attention Needed: Shift to Park" accompanied by audio alerts inside and outside of the vehicle. This is obviously unsafe as the vehicle cannot be parked and turned off reliably.

I purchased this vehicle from East Bay BMW in Pleasanton, CA on April 8, 2023. On August 28, 2023, to September 4, 2023, I began to receive messages on the dashboard stating shift to park. The shift lever was in park but was not registering this. I had to wiggle the shift lever to get the message to go away and be able to turn my vehicle off. On September 5, 2023, I had the same issue but this time no matter what I did the message would not go away and I was not able to turn my car off for 10 minutes. On September 5, 2023, I called the dealership and spoke with [XXX] -the Service Advisor who told me he would need to speak with his colleagues and get back to me. As of today September 5, 2023.

This is a Legitimately Serious Concern regarding GM Vehicles (including Chevrolet) and Dealer Service Compliance with "Safety Warnings" and Reliability Warnings as in Factory Service Manuals. Specifically "Single Use Fasteners" and "Do Not Use Air-Impact on Brake System Fasteners" and "TTY Fastener Dual Pass Torque-to-Yield Specifications" . . . 1.) Widespread Non Compliance with Single Use Brake Components (Fasteners, Seals, Bellows) - every set of Brake-Pads / Rotor Replacement should show corresponding Parts Billing. 2.) Shortcuts to Brake System Service by using Air-Wrench removal / installation using Torture-Sticks. 3.) Multiple Different Torque Specifications for each Component / Fastener (upper/lower/front/rear) likely also 'Shortcuts Taken by using Air-Wrench Torque-Sticks vs Precision Torque Wrench (Pass1=Torque, Pass2 = Rotation Degrees) Seriously these are all called out in the Factory Service Manuals. To inspect, without biasing discovery, but easily, a video (shop security cam) review would easily confirm NONCOMPLIANCE of Impact-Wrench Use on Brake Component Fasteners and TTY Fasteners Protocols and a Simple Review of Brake Rotors should show at least 2 NEW TTY Fasteners per each New Rotor used (check invoices for Rotor Replacement Services). This is NOT A Trivial Picky Customer Concern . . . It is a *Serious Safety Concern* . . . Check the Factory Service Manual, note that most likely inventory control doesn't show TTY Single use Fasteners / Rotor Replacement correlation . . . See Service Manual WARNING . . . Consult your Liability Attorneys to estimate the Cost of Urgent Safety Recall for Dealer Serviced Rotors/Brakes. . . . Compliance is not a Nice To Do Thing . . . Compliance is Mandatory Engineering Factory Service Manual Specifications. Period.

Started in late summer/fall of 2022 getting 'shift to park' error. The vehicle is in park and unable to turn off the vehicle when I get this error. I have noticed the error is more prone to come on when the parking break is also engaged or if it's on any sort of hill but I cannot pinpoint the cause of the annoying error. Sometimes I could spend 5 minutes or more getting the error to clear--usually am able to clear by doing a combination of moving/turning on/off the parking break, the shift and/or turning on/off the car and/or opening the door.

2019 Chevy Volt gave a Shift to Park message when vehicle was already in Park. Could not turn off vehicle. Had to restart Volt, then take out of park, but back in park and message disappeared and was able to safely leave vehicle.This happened approximately 6 times in one outing. Also somehow the electric parking brake light came on the dash console but I had not applied the parking brake yet!! No symptoms, warning lamps, or messages before this happened. Have not made appointment yet to take to dealer to get repaired - hopefully under warranty.

VEHICLE SPEED CONTROL
I was getting on the I15 freeway. After I entered, I set the cruise control and it immediately began to accelerate the vehicle to maximum speed. I was unable to turn it off and had to repeatedly push the brakes to keep the speed below 70 + mph. Smoke from the brakes began to fill the passenger compartment. I got off the freeway and when I slowed to about 20 mph, I heard a clunk under the dash and the cruise control turned off. I drove home the rest of the way without cruise control without incident. I am taking the car to a Chevy dealer today to investigate the cause.

Lake Placid, FL
POWER TRAIN:AUTOMATIC TRANSMISSION:LEVER AND LINKAGE:FLOOR SHIFT
Intermittently, the car would not turn off, starting in about July, 2022. After shifting the car into park and pressing the On/Off switch, the car displayed a message like "Action required. Shift to park". It was impossible to know if the car really was not in park, and would roll into someone, and it was certainly unsafe to walk away and leave the car "on". A Chevy forum showed that this problem is COMMON and pointed me to GM TSB 19-NA-206 (https://static.nhtsa.gov/odi/tsbs/2020/MC-10171895-9999.pdf). The TSB exactly describes the symptom I observed and lists one of the exact parts that the Huston Chevrolet service department replaced on 8/3/2022 - 84733196 N-Harness. The dealer, Chevrolet customer service, and GM customer service all told me that this repair was not covered under warranty, though the TSB says this on page 4: "Specific to the Volt model, repairs are covered under the Voltec (Electric and Hybrid Vehicle) Warranty." GM said that I would have received a letter if the TSB applies to my specific car. I paid Huston Chevrolet $446.79 to repair this problem, and believe the manufacturer should 1) reimburse me for the cost and 2) notify other owners about this common and dangerous manufacturing defect.
