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 2011 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.

NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States.

The subject vehicles, which employ emerging technology, are range-extended electric vehicles that utilize a high voltage (HV) battery to provide energy for propulsion. The HV battery is lithium-ion based technology that has a nominal full charge of 390 VDC, a 16 kWh capacity, and a control system that incorporates liquid (antifreeze) cooling and various electronic devices (control modules, sensors, wiring, etc) to monitor and manage the HV battery.

Recalls on the 2011 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.

United States — NHTSA

15V145000

ELECTRICAL SYSTEM:IGNITION

General Motors LLC (GM) is recalling certain model year 2011-2013 Volt vehicles manufactured August 25, 2010, to June 26, 2013. If the driver exits the vehicle without turning off the electrical system, the battery may drain low enough that the gasoline engine will automatically start itself to recharge the electric battery.

Risk: If the engine runs for an extended period of time in an enclosed space, there may be a build up of carbon monoxide, increasing the risk of personal injury.

Recalls cover specific build ranges, so check your own vehicle by VIN at nhtsa.gov/recalls or, in Canada, Transport Canada.

Cincinnati, OH Crash

SERVICE BRAKES

I was stopped at a red light with my foot on the brake. When the light turned green, I released the brake and the car suddenly accelerated forward on its own, without me touching the accelerator. As soon as the car surged forward, I immediately pressed the brake pedal hard to stop it but instead of slowing down, the car continued to accelerate. It felt like pressing the brake was making it worse. The car was totally out of my control. The vehicle collided with tow truck and even after the impact, the engine was still revving as if it was trying to keep going. I had to shut the car off to stop it completely. There were no warning lights or error messages before or during the malfunction. The front end of my car was damaged in the crash. No one was injured, but the malfunction could have easily caused serious harm or death. This was not user error it was a terrifying mechanical and electronic failure. The car accelerated on its own and the brakes failed or possibly triggered more acceleration. I have never experienced anything like this. After looking online, I found other Volt owners reporting similar problems involving brake assist failure, unintended acceleration, and stuck revving. This looks like a serious pattern that deserves urgent attention. I’m asking the National Highway Traffic Safety Administration (NHTSA) and General Motors to immediately investigate this issue. I want to know if there are any recalls, technical service bulletins (TSBs), or known defects related to brake failure or unintended acceleration in the 2011 Chevy Volt. Please contact me with next steps. This is a major safety risk that could easily result in fatalities if not addressed.

EXTERIOR LIGHTING

The contact owns a 2011 Chevrolet Volt. The contact stated that water was accumulating inside the driver's side taillight assembly. The contact stated that the water caused a short circuit in the taillight, and the passenger’s side turn signal became inoperable. The contact had taken the vehicle to an independent mechanic where it was diagnosed, and determined that the wiring harness for the driver's side taillight assembly needed to be replaced. The vehicle was not repaired. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline. The failure mileage was approximately 97,000.

STEERING

'11 Chevy Volt hybrid was daily driver of 100+ miles, multiple trips both highway and city for last 2 1/2 months. Breaks and rotors have been replaced all the way around, fresh oil changes as needed and filters. Warning on dash "Service High Voltage Charging System", ”Service Airbag" and check engine light have been on since I've owned it (Oct. 23). When plug car in it doesn't charge, but the EV charges while driving. Car generally switches back and forth from EV to ICE without issues. No other issues have been noted. 1/18/24 Start car and drive all day for work. Total of 129 miles between 22 trips. Last trip car sat for 30 minutes after running deliveries all day. Started as normal, turned off at gas station, filled tank with premium, restarted and drive to freeway. Drove 20 miles, pulled over to text, put car in park. 5 mins later took out of park and car wouldn't move. Inside had complete power, radio, windows, ect. Only noticable difference was car would get no acceleration, power steering went out, and heat started blowing cooler air. Absolutely no warning and car just cuts off engines. Thankfully I was parked safe. Towed home, replaced 12v. Started and drove no problem on 1/19/24. No new warnings or anything different. Started up 1/20/24 drove 7 miles and the engines cut off in the middle of a main road while accelerating, once again no warning. Luckily got into turn lane before almost getting hit. Still not sure what's wrong with car. Same codes. No battery warning or loss of power indication at all. Just up and cuts off. This is very very dangerous and needs to be looked into please. When my volt died today the truck behind me had to slam on his brakes and came inches from hitting me. If this would've happen on the freeway, I'd likely been hit.

FUEL/PROPULSION SYSTEM

The car quit running when my wife was driving the car when the mileage range went down to 4 miles range remaining. The car was towed to the local Chevrolet dealership who charged over $1,000 to reset the electronics so car would run. I was advised that if battery range was run down to a low mileage range that car would quit running again and that it would have to be towed back to the dealership for the electronics to be reset. I was concerned about liability if anyone drove car and it stopped on highway. It was clear to me that the only way out of potential liability, associated with the car stopping on the highway was to sell the car for salvage. I purchased this Chevrolet Volt Premier new. It was never in a collision or damaged in any way. The car was sold for with approximately 81,000 miles for $2,013.

SERVICE BRAKES

Several times over the 2 years I have owned this vehicle while driving an almost complete loss of braking occurs with a service notice for the ABS system. If you turn off the ignition and restart it the braking works fine. I am in the process of having the Electronic Brake Control Module - GM (84070136) and the Brake Pressure Modulator Valve - GM (23283683) replaced. i believe that there is a design flaw in this system in that a problem of the ABS should not eliminating the ability to stop the vehicle. This is costing me $3500, but the point is that loss of braking is a serious safety issue and should be addressed by the manufacturer. Thank you.
