From checking the specialized coolant loops to maximizing your electric miles, we have gathered the data and field experience you need. Let’s dive into the technical details and real-world performance of this innovative Chevy.
Understanding the Voltec 4ET50 Electric Drive Unit
The heart of the 2013 Volt is the Voltec 4ET50 electric drive unit, a sophisticated piece of engineering that manages power between two electric motors and the gasoline engine. Unlike a traditional hybrid, the Volt primarily uses its electric drive motor-generator to propel the wheels. This provides that instant torque and silent acceleration that EV enthusiasts love.
The system is designed to be seamless, but as a DIYer, you should know how it transitions. The larger motor handles most of the driving, while the smaller motor can act as a generator or assist during high-speed cruising. If you notice a “stumble” during the transition from battery to gas, it often points to a software update or a sensor issue rather than a mechanical failure.
Reliability for this unit has been surprisingly high, but it relies heavily on the inverter-converter power module. This module converts the DC power from the battery into AC power for the motors. Keeping the electrical connections clean and ensuring the cooling system is functional are the best ways to prevent expensive electrical repairs in this area.
The 16.5 kWh Lithium-Ion Battery Pack
For the 2013 model year, Chevrolet bumped the battery capacity to a 16.5 kWh lithium-ion battery pack. This increase provided a slight boost in range over the previous year, typically allowing for 35 to 40 miles of pure electric driving. For most commuters, this means the gasoline engine rarely needs to fire up during the work week.
If you are inspecting a used Volt, use an OBD-II scanner to check the battery’s capacity and cell balance. While these packs are robust and feature an active thermal management system, they do degrade over time. Look for consistent range estimates on the “Efficiency Leaf” screen to gauge the health of the cells before you buy.
The 1.4L LUU Range Extender Engine
When the battery reaches a low state of charge, the 1.4L LUU range extender engine kicks in. It is important to remember that this engine acts primarily as a generator. It doesn’t have a traditional transmission; instead, it provides electrical energy to the motors or helps turn the wheels through a planetary gear set at high speeds.
Because this engine may sit idle for weeks if you drive mostly on electricity, it is prone to “stale fuel” issues. Chevrolet included a pressurized Chevrolet Volt fuel tank size and system to mitigate this, but you should still perform regular oil changes. Even if the odometer says you’ve driven 10,000 miles, the engine might only have 1,000 miles of actual runtime.
2013 chevrolet volt review – Reliability and Common Diagnostic Codes
In any 2013 chevrolet volt review, we have to address the “Check Engine” light, which can be more intimidating on a hybrid. One of the most frequent codes owners encounter is the P1E00 diagnostic trouble code. On its own, P1E00 simply tells the car’s computer to turn on the MIL (Malfunction Indicator Lamp) because the hybrid control module has detected a fault.
To find the real problem, you need a scanner capable of reading “manufacturer-specific” codes. Often, the P1E00 is accompanied by codes related to the charging system or the coolant level. A common culprit is a slightly low level in the battery coolant reservoir, which triggers a sensor to prevent the high-voltage system from charging as a safety precaution.
Another area to watch is the regenerative braking system actuator. This system blends traditional friction braking with electric motor resistance to recharge the battery. If the brake pedal feels “mushy” or inconsistent, it may require a specialized bleed procedure using a scan tool to cycle the valves in the ABS/Regen module.
The “Service High Voltage Charging System” Message
This is perhaps the most dreaded message for a Volt owner. It often prevents the car from taking a charge from the J1772 charging port. While it sounds expensive, it is frequently caused by a faulty coolant level sensor or a small leak in the high-voltage battery coolant loop. Check your reservoirs before assuming the battery is dead.
Common Mechanical Failures
- Bearing Failure: A high-pitched “sawing” noise from the motor area often indicates a failed motor bearing.
- Stuck Charge Door: The 2013 model uses a push-to-release door that can freeze or stick due to road grime.
- 12V Battery Issues: A weak 12V AGM battery in the trunk can cause a cascade of “ghost” electrical errors.
Essential DIY Maintenance for Volt Owners
Maintaining a Volt is different from a standard car, but it is very manageable for a DIYer. The most critical task is managing the three separate cooling loops. The engine, the high-voltage battery, and the power electronics each have their own dedicated cooling systems. You must use the correct Dex-Cool engine coolant mixed with deionized water to prevent internal corrosion.
When changing the oil on the 1.4L engine, use a high-quality 5W-30 full synthetic oil that meets the Dexos1 specification. Since the engine runs intermittently, it can be prone to moisture buildup. Using the remote start system to pre-condition the car while plugged in can actually help the engine by reducing the load during cold starts.
Don’t forget the cabin air filter and the engine air filter. Because the Volt is so quiet in EV mode, a dirty cabin filter can lead to noticeable odors or whistling noises. These are simple, 10-minute jobs that improve the ownership experience significantly without requiring a trip to the dealership.
Fluid Replacement Intervals
- Engine Oil: Every 2 years or when the oil life monitor indicates (whichever comes first).
- Brake Fluid: Every 2 to 3 years to prevent moisture from damaging the complex regen-braking valves.
- Coolant Loops: Inspect levels monthly; flush and replace every 5 years or 150,000 miles.
Unique Value Element: Symptom-to-Cause Matrix
| Symptom | Probable Cause | Recommended Action |
|---|---|---|
| Will not charge; “Service HV System” | Low battery coolant or sensor fault | Check reservoir level; inspect for leaks. |
| Whirring noise while slowing down | Motor generator bearing wear | Inspect drive unit; professional repair likely. |
| Strange dash errors / No start | Failing 12V AGM battery | Test and replace the trunk-mounted 12V battery. |
| Engine runs even when battery is full | Engine Maintenance Mode (EMM) | Normal behavior; let the cycle finish. |
Interior Comfort, Cargo, and Technology
Inside the 2013 Volt, you are greeted by a futuristic (for its time) center console with touch-sensitive buttons. While these can be finicky with gloves on, the dual-screen setup provides excellent feedback on energy usage. The seats are supportive, but the T-shaped battery pack running down the center of the car means this is strictly a four-seater.
Cargo space is decent for a hatchback, though the floor is somewhat high to accommodate the electrical components. If you are an off-roader or a rider, don’t expect to fit a motorcycle in the back, but it easily swallows a mountain bike with the front wheel removed. The cabin is remarkably quiet, thanks to extensive sound-deadening and the lack of engine vibration in EV mode.
The MyLink infotainment system in the 2013 model was a significant step up from the 2012. It offers Bluetooth streaming and a reasonably responsive interface. For the tech-savvy owner, adding a modern CarPlay or Android Auto interface via a third-party module is a popular DIY upgrade that breathes new life into the cockpit.
Is the 2013 Chevrolet Volt Still a Good Buy?
As we conclude this 2013 chevrolet volt review, the question remains: should you buy one? If you have a place to plug it in at night, the answer is a resounding yes. It offers a level of refinement and fuel savings that few cars in its price bracket can match. Even if the battery has lost 10% of its original capacity, you are still looking at 30+ miles of gas-free driving.
From a DIY perspective, the Volt is a rewarding vehicle. While the high-voltage system requires caution (always look for the orange cables and follow safety protocols), the mechanical side of the car is very accessible. Parts are widely available, and the community of “Volters” is incredibly active and helpful when it comes to troubleshooting obscure issues.
The main trade-off is the four-seat configuration and the requirement for premium fuel in the range extender. However, since you will rarely use the gas engine if your commute is short, the fuel cost is negligible. If you find a well-maintained example with a clear service history, it represents one of the best values in the used “green” car market today.
