About This Data

The 2008 Chevrolet Impala has an MOT pass rate of 40.0% based on 40 tests — significantly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 107,730 miles on the odometer. With a 60.0% failure rate, the 2008 Impala is rated as "Very Poor" for MOT reliability.

If you own or are considering buying a 2008 Chevrolet Impala, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to lamps, reflectors and electrical equipment: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test. With an average mileage of 107,730 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.

Lamps, reflectors and electrical equipment — 40.0% of failures

Lamps, reflectors and electrical equipment issues account for 40.0% of MOT failures on 2008 Chevrolet Impala models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.

Tyres — 15.0% of failures

Tyres issues account for 15.0% of MOT failures on 2008 Chevrolet Impala models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.

Noise, emissions and leaks — 5.0% of failures

Noise, emissions and leaks issues account for 5.0% of MOT failures on 2008 Chevrolet Impala models. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: £100–1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.
