Opel Ampera Ampera — Problems & Common Faults

The Opel Ampera (2011–2015) is a first-generation Chevrolet Volt with an Opel badge — built in Hamtramck (Michigan, USA). A range extender with electric drive and a petrol engine acting as generator. Over 40,000 EUR at launch, now a bargain on the used market. Technically a fascinating concept: 40–60 km purely electric, then the combustion engine kicks in as a generator. Anyone who understands and maintains the system gets a technically sophisticated vehicle with low running costs. In pure electric mode, the Ampera is whisper-quiet and drives like a modern EV.

Engine choice: There is only one powertrain — the A14NET-based 1.4 range extender (86 PS thermal) plus two electric motors with 111 kW system output. The combustion engine never directly drives the wheels — it generates electricity. The T-shaped lithium-ion battery (16 kWh, usable approx. 10.5 kWh) in the centre tunnel is the heart of the car. GM managed the battery conservatively — only 65% of capacity is used, extending lifespan. Examples with 150,000+ km often still show 80–85% residual capacity. Mixed-mode consumption is 1.5–3.0 litres per 100 km when charged regularly.

Weak points: The biggest risk with the Ampera is the complexity of the hybrid system. When the control unit (BECM — Battery Energy Control Module) throws errors, it gets expensive — diagnosis only possible with GM-specific Tech2/GDS2 diagnostic equipment, independent workshops are often out of their depth. Repair costs for the BECM or power electronics can reach 2,000–5,000 EUR. The 12V auxiliary battery frequently dies after 3–4 years — and when it is flat, the car cannot be unlocked or started (80–150 EUR, but boot access required). Coolant pump for the battery fails from 80,000 km — warning message in the display, battery is no longer cooled, act immediately (300–600 EUR). Charge port flap jams in frost — mechanical issue, actuator seizes (100–200 EUR). The range extender itself is robust, but coolant thermostat and water pump are identical to the Astra J issue (water pump 280–600 EUR).

Test drive checklist: Start fully charged and check the electric range in the display — under 30 km indicates battery degradation. Switch to range extender mode — does the combustion engine start cleanly? Does it run smooth or vibrate unusually? OBD diagnosis with Torque Pro or myGreenVolt app: read out battery State of Health. Switch on air conditioning — does the electric compressor work? Check 12V battery voltage with the system running (should be >13.5V). Test charging: plug in, verify charge initiation.

Buying advice: Market prices in 2026 have dropped to 4,000–8,000 EUR — for 2012–2014 models with 80,000–120,000 km. Good examples exist under 5,000 EUR. Insider tip: prefer model year 2013 or 2014 — software updates and BECM improvements are integrated from the factory. Service book with Opel/GM stamps matters because independent workshops rarely maintain the hybrid system correctly. Anyone with a home charger and a commute under 50 km can run the Ampera almost purely electric — petrol costs practically zero. A technically fascinating car for hands-on owners who are not afraid of high-voltage systems.
