Gen1 (2012–2016) — Engine options included the 1.4 Petrol/Electric Hybrid, 1.4 Range Extender Electric. We track 5 known issues on this generation, with 2 classified as significant. The most significant concern is Engine management light illumination.
The hybrid powertrain control system triggers persistent engine management light illumination at rates significantly higher than conventional vehicles. This affects the integration between the 1.4-litre petrol engine, electric motor, and battery management systems. The fault often relates to emissions system monitoring or battery thermal management conflicts. Unlike conventional cars where MIL illumination is often minor, hybrid system faults can affect vehicle operation and charging capability.
Hybrid system faults can reduce fuel economy, prevent charging, or force the vehicle into reduced power mode. Diagnostic costs are typically high due to specialist hybrid expertise requirements. Complex faults involving battery thermal management or motor controllers can cost £1,000-£3,000 to resolve.
Check all electrical functions systematically: windows, mirrors, lights, infotainment, heated seats, air conditioning. Look for any warning lights on the dashboard. A diagnostic scan before purchase can reveal stored fault codes.
The conventional 12V battery experiences accelerated degradation due to the constant electrical loads from the hybrid system's control modules and the infrequent running of the petrol engine to charge it. Unlike conventional cars where the alternator regularly charges the battery, the Ampera relies on a DC-DC converter from the high-voltage traction battery to maintain the 12V system. Battery failure can prevent the vehicle from starting or entering ready mode.
12V battery failure prevents the vehicle from entering ready mode, effectively immobilising it. The hybrid system requires the 12V battery to initialise before the high-voltage system can operate. Replacement batteries cost £100-200 but require hybrid system recalibration at some dealers, increasing labour costs.

The constant velocity joint boots on the driveshafts deteriorate at rates significantly higher than the average vehicle, with both severe deterioration and complete loss of boots documented. This appears related to the specific driveshaft design used to accommodate the electric motor integration within the transmission housing. Boot failure allows dirt and water ingress, leading to CV joint wear and eventual replacement of the entire driveshaft assembly.
If the boot splits are caught early, replacement costs £100-200 per side. If dirt ingress damages the CV joint, the entire driveshaft requires replacement at £300-500 per side. The car remains safe to drive with damaged boots but CV joint failure will eventually cause loss of drive to one wheel.
Listen for clunking or vibration from underneath when pulling away or changing direction. Check for play in the driveshafts by rocking the car in gear with the handbrake on. Worn CV boots are a telltale sign — look for grease splatter around the inner wheel arch.
The front brake discs warp or develop surface irregularities at rates significantly higher than conventional vehicles, causing brake judder and uneven brake effort. This is likely related to the regenerative braking system's interaction with the conventional hydraulic brakes. The hybrid system's intermittent use of the friction brakes can lead to uneven heating and cooling cycles, promoting disc distortion.
Warped discs cause uncomfortable braking judder and can reduce braking effectiveness. Disc replacement typically costs £200-400 for both front discs including labour. The condition worsens progressively and may accelerate brake pad wear on the affected discs.
Check brake disc condition for lipping or scoring. Test braking at moderate speed for pulling to one side or vibration through the steering wheel. Review MOT advisories for brake-related items.
Front suspension pins, bushes, and joints show accelerated wear compared to conventional vehicles, particularly affecting the lower control arm bushes and anti-roll bar links. The additional weight of the battery pack and electric motor may contribute to increased suspension loading. This manifests as increased road noise, reduced handling precision, and eventual MOT failure for excessive play in suspension joints.
Worn suspension components reduce ride comfort, handling precision, and tyre life through poor wheel alignment. Replacement of control arm bushes or anti-roll bar links typically costs £200-400 per side. The vehicle remains safe to drive but will eventually fail MOT testing for excessive suspension play.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.

Based on 6k real DVSA MOT tests, the Vauxhall Ampera fails more often than average on several items. The biggest outlier is light unit fault at 24x the fleet average, followed by emissions failure (9x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Vauxhall Ampera MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 20k miles) typically costs £120–£180 at an independent garage.
