Steering — 3.9% of failures
Steering issues account for 3.9% of MOT failures on 1993 General Motors Unclassified models. Steering failures include excessive play in the steering wheel, leaking power steering fluid, worn track rod ends, and damaged steering rack. These affect vehicle control and are closely related to suspension wear. Typical repair costs: £150–600. Pre-MOT check: Check for excessive steering wheel play (more than a few inches of free movement). Listen for whining from the power steering pump. Look for fluid leaks under the car near the front wheels.
Noise, emissions and leaks — 2.0% of failures
Noise, emissions and leaks issues account for 2.0% of MOT failures on 1993 General Motors Unclassified 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.
Non-component advisories — 2.0% of failures
Non-component advisories issues account for 2.0% of MOT failures on 1993 General Motors Unclassified models. Non-component advisories issues are a common cause of MOT failure. Regular inspection and maintenance of these components helps ensure your vehicle passes its MOT. Typical repair costs: £100–400. Pre-MOT check: Have this system checked during regular servicing. Look for warning signs like unusual noises, vibrations, or dashboard warning lights.
