Chrysler Viper MOT Reliability Overview
The Chrysler Viper is a rare vehicle in the UK, with 312 MOT test results recorded in our database spanning 3 manufacture years. It has an overall MOT pass rate of 90.4% and a failure rate of 9.6%, which is well above the UK average of approximately 37%.
Based on this data, the Chrysler Viper earns a "Excellent" reliability rating. The average Chrysler Viper presents for MOT with approximately 37,835 miles on the clock. Manufacture year matters: 1998 models achieve the highest pass rate at 100.0%, while 1994 models have the lowest at 87.9%. This 12.1 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Chrysler Viper is Suspension, affecting 11.2% of all tests. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. The second most common issue is Lamps, Reflectors and Electrical Equipment at 4.8%. Exhaust, Fuel and Emissions rounds out the top three at 3.5%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

Use our detailed year-by-year breakdown and failure analysis below to understand how your specific Viper is likely to perform.
Suspension — 11.2% of failures
Suspension issues account for 11.2% of MOT failures on the Chrysler Viper. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Lamps, Reflectors and Electrical Equipment — 4.8% of failures
Lamps, Reflectors and Electrical Equipment issues account for 4.8% of MOT failures on the Chrysler Viper. 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.
Exhaust, Fuel and Emissions — 3.5% of failures
Exhaust, Fuel and Emissions issues account for 3.5% of MOT failures on the Chrysler Viper. 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.
