2014 Chevrolet Volt — Known Issues & Recalls

Your passenger airbag sensor is faulty and may not deploy in a crash, putting your passenger at risk. The sensor was previously replaced but the problem persists. This appears to be a widespread issue affecting 2014 Volts, though older model years have a recall for this system. Fixing this will likely require a complete replacement of the faulty airbag sensor module.

Your air bag warning light turns on every day, indicating a malfunction with the passenger side air bag sensor. A technician has warned that this sensor failure could prevent the passenger air bag from deploying properly during a crash, which could result in serious injury. This issue needs immediate attention to restore proper air bag protection.

Your car's front passenger airbag system has detected an electrical short in the presence detection module, which is responsible for determining if someone is sitting in the front passenger seat. This could prevent the passenger airbag from deploying properly in a crash. The diagnostic code indicates the module needs to be replaced.

Your Service Airbag warning light is turning on and off intermittently. A dealer has confirmed this is caused by a faulty passenger occupancy sensor, which appears to be a recurring issue affecting multiple 2014 Chevy Volts. Repair costs are estimated between $1,000-$1,200. Fixing this will require replacing the defective occupancy sensor.

Your dashboard intermittently displays a service airbag warning and automatically disables the passenger airbag, even though your car has never been in an accident or damaged. This appears to be a known issue affecting many 2014 Volts. The repair costs around $1,000 and involves diagnosing and replacing the faulty airbag system component or sensor.

While driving at 55 mph and attempting to merge, your Volt suddenly hesitated and shut off in traffic. The dealer diagnosed a failed battery as the cause. This is a serious safety concern since the engine unexpectedly died while you were actively driving. The battery will need to be replaced to restore normal operation.

Your 2014 Volt lost all power and stalled without warning while driving at 40 MPH. An independent mechanic diagnosed a battery failure as the cause. The manufacturer informed you that the free replacement warranty period had already expired, so you're responsible for the repair cost.

Your car's main battery pack suddenly stopped working while you were driving on the highway with no warning signs beforehand. This left you without power while driving. The issue may require battery pack replacement or diagnosis of the charging system.

GM has disabled the OnStar feature on your 2014 Volt because it uses older 2G cellular connectivity. Canadian owners were offered a free upgrade to 4G connectivity to restore the feature, but U.S. owners have not received the same option. GM has the technical capability to perform this upgrade, as documented in their service bulletin, but is not offering it to American customers.

Your car suddenly surged forward and hit your garage wall while you were slowly backing in, even though you were only lightly braking and not accelerating. Your car had been showing a "Propulsion Power is Reduced" warning and wasn't holding an electric charge, but the malfunction indicator light never came on, so you thought it was safe to drive based on the owner's manual. The unexpected surge caused severe damage to your garage, and your insurance company totaled the vehicle.

Your car loses power and jerks suddenly while driving, especially on hills or the freeway, which feels unsafe and unpredictable. The dealership has been unable to reproduce or fix the issue despite multiple visits, and you've discovered this is a known problem affecting other Volt owners. The problem also involves a high voltage electrical issue and a coolant sensor that gives incorrect readings. Resolving this will likely require diagnostic testing of the electrical system, high voltage battery connections, and engine sensors to identify the root cause of the power loss.

Your Volt has stalled multiple times when switching from battery power to the gasoline engine, leaving you unable to drive. The lithium battery isn't charging properly, which causes the engine to shut down once the battery is depleted. This has happened at least three times since February 2022, and despite diagnostic service and error code clearing at dealerships, the problem persists. The repair will likely involve diagnosing and replacing the battery management system, charging components, or the hybrid power control module.

Your car suddenly stopped working at a stoplight with only a brief "Propulsion power is reduced" warning message beforehand. After restarting, the car barely limped out of traffic and became nearly impossible to shift into neutral for towing. The dealer resolved the issue by replacing the engine control module.

Your car's engine power feels noticeably weaker than normal. This reduced propulsion could affect acceleration and overall driving performance. A mechanic will likely need to diagnose the fuel system, ignition system, or engine controls to identify and fix the underlying cause.

Your car is losing power while driving and moving slower than normal. This could indicate an issue with the engine or propulsion system that needs diagnostic evaluation. A mechanic will likely need to scan the vehicle's computer and inspect the fuel and ignition systems to identify the cause.

Your car's propulsion system suddenly reduced power and shut down completely while you were driving at highway speeds (50 mph), forcing you to push the vehicle off the road to avoid traffic. After restarting the car 15 minutes later, it shut down again a quarter mile down the road while you were turning across traffic. This has happened at least three times, including a previous incident on a toll road that required a tow truck. The fix will likely involve diagnosing the fuel/propulsion system for electrical or fuel delivery failures that cause unexpected shutdowns.

Your Volt has lost all power and won't start or move, even though the hybrid battery is fully charged. This is a continuation of reduced power issues you've reported multiple times over the years—the dealer previously applied a software update that temporarily helped, but the problem has returned now that the warranty has expired. The issue likely involves the high-voltage battery system and may require battery testing, diagnostics, or battery replacement to restore proper function.

Your 2014 Volt's electric battery system failed completely when the battery depleted, causing the car to enter a reduced power mode instead of switching to the gas engine normally. You were able to limp drive home a short distance, but afterward the car became completely immobile and needed a tow truck. The dealer found that a single failed cell in the traction battery caused the entire battery pack to fail, requiring a $22,000 replacement—and this is the second time this same issue has happened to your car.

Your passenger-side airbag sensor is malfunctioning, causing an alarm to cycle repeatedly whenever someone sits in the passenger seat. This suggests the sensor isn't properly detecting the passenger and may be turning the airbag on and off, which could be a safety problem in a crash. The fix will likely involve replacing the faulty passenger presence sensor.

Your Volt's hybrid propulsion system may unexpectedly lose power while driving, causing the engine to rev without responding to the accelerator and the car to slow down on its own. A "Propulsion Power Reduced" warning message appears, and the issue may happen repeatedly at various speeds before normal operation returns. The dealer couldn't reproduce the problem during service visits, so no repair was completed. Fixing this may require diagnostic scanning of the hybrid system's control modules and possible replacement of affected sensors or electrical components.
