2011 Chevrolet Volt

Posted
By Research the Car 4 min read

The 2011 Chevrolet Volt was a groundbreaking plug-in hybrid electric vehicle (PHEV). It featured a 1.4L inline-4 gasoline engine (83 hp, 85 lb-ft of torque) that acted as a generator to extend the range after the battery was depleted. The primary propulsion came from a 111-kW (149 hp) electric motor. Many owners loved the Volt for its electric driving experience, fuel efficiency, and innovative technology. Common complaints included the limited all-electric range, the complexity of the powertrain, and some reported reliability issues.

Electric Motor

  • Reduced Propulsion Power Message/Loss of Power
    • Description/Symptoms: Owners report experiencing a “Reduced Propulsion Power” message on the dashboard, followed by a significant reduction in power or even complete inability to drive. This often occurs due to issues within the battery management system or the high voltage components of the electric drive system.
    • Solution: Diagnosis requires specialized equipment to read the Volt’s diagnostic trouble codes. Technicians will typically check the battery modules, battery management system, and the inverter/converter system. Replacing faulty modules or components is usually the required repair.
    • Estimated Cost to Fix: $500 - $6000+ (depending on the component needing replacement, with battery issues being the most expensive)
    • Recalls: None Found

Range Extender Engine

1.4L Inline-4 (Range Extender)

  • Engine Hesitation/Stalling
    • Description/Symptoms: Some owners have reported hesitation or stalling of the 1.4L engine, particularly when it engages as a range extender. This can manifest as a sudden loss of power or a rough-running engine.
    • Solution: Possible causes include a faulty mass airflow (MAF) sensor, a dirty throttle body, or issues with the fuel injectors. Cleaning the throttle body, replacing the MAF sensor, or cleaning/replacing the fuel injectors may resolve the issue. Sometimes a software update for the engine control module (ECM) is necessary.
    • Estimated Cost to Fix: $100 - $500+ (depending on the component)
    • Recalls: None Found
  • Engine Oil Consumption
    • Description/Symptoms: Some owners have reported excessive engine oil consumption, leading to low oil levels and potential engine damage if not addressed.
    • Solution: Regular oil level checks are crucial. If excessive consumption is confirmed, possible causes include worn piston rings or valve seals. Repairs can range from a simple PCV valve replacement to a more extensive engine rebuild.
    • Estimated Cost to Fix: $50 - $3000+ (depending on the cause and extent of repair)
    • Recalls: None Found

Transmission

No Issues Found

Battery

  • Battery Capacity Degradation
    • Description/Symptoms: Over time, the battery capacity in the 2011 Volt can degrade, resulting in a reduced all-electric range. This is a natural process for lithium-ion batteries, but some owners experienced more significant degradation than expected.
    • Solution: There is no simple fix for battery capacity degradation. The battery can be tested to determine its current state of health. Replacement of individual battery modules or the entire battery pack is the only permanent solution.
    • Estimated Cost to Fix: $500 - $6000+ (depending on the component needing replacement, with battery issues being the most expensive)
    • Recalls: None Found

Electrical

  • Charging Issues
    • Description/Symptoms: Owners report difficulty charging the Volt, either through a Level 1 (120V) or Level 2 (240V) charger. This can manifest as the car not recognizing the charger, charging stopping prematurely, or error messages appearing on the dashboard.
    • Solution: Diagnosing charging issues can be complex. Potential causes include a faulty charging port, a malfunctioning onboard charger, or problems with the charging cable itself. The issue could also be related to the vehicle’s software.
    • Estimated Cost to Fix: $100 - $1000+ (depending on the component needing replacement)
    • Recalls: None Found
  • “Service High Voltage Charging System” Error
    • Description/Symptoms: This error message indicates a problem within the high-voltage charging system. It can be triggered by a variety of issues, including problems with the charger, battery management system, or high-voltage wiring.
    • Solution: Requires professional diagnosis using specialized diagnostic tools to pinpoint the exact cause of the error.
    • Estimated Cost to Fix: $200 - $1500+
    • Recalls: None Found
  • Dead 12V Battery
    • Description/Symptoms: The 12V battery, responsible for starting the car and operating auxiliary systems, can fail prematurely.
    • Solution: Replace the 12V battery.
    • Estimated Cost to Fix: $100 - $300
    • Recalls: None Found

Suspension

No Issues Found

Exterior

No Issues Found

Interior

  • HVAC Actuator Failure
    • Description/Symptoms: Clicking or popping noises behind the dashboard, along with inconsistent temperature control, often indicate a failing HVAC actuator. These actuators control the flow of air to different vents and can become faulty.
    • Solution: Replacement of the failed HVAC actuator. This can be a labor-intensive job, as accessing the actuators often requires removing parts of the dashboard.
    • Estimated Cost to Fix: $200 - $600+

Summary

The 2011 Chevrolet Volt, while innovative, can present owners with a range of issues. Electrical and battery-related problems are common and can be costly to repair, particularly if battery module replacement is needed. Engine-related problems, while less frequent, can also be expensive depending on the severity. The overall reliability of the 2011 Volt appears to be below average when compared to other vehicles. Prospective buyers should be aware of these potential issues and carefully inspect any used Volt before purchasing.
