Most Common Smc Cg MOT Problems by Failure Category

Every MOT failure a tester records belongs to one inspection section of the DVSA manual. For the Smc Cg, the Lamps, reflectors and electrical equipment section leads the record — the breakdown below shows where the recorded failures cluster, then the exact strings behind the three biggest sections.

Inspection section Share of failures Est. recorded instances
Lamps, reflectors and electrical equipment 49% 18
Brakes 30% 11
Identification of the vehicle 11% 4
Tyres 5% 2
Visibility 3% 1
Suspension 3% 1

Shares are over the Smc Cg's recorded defect strings, merged across its year pages.

Lamps, reflectors and electrical equipment

Around 49% of the recorded Smc Cg failures fall in the Lamps, reflectors and electrical equipment section of the MOT inspection manual. Testers recorded "Individual direction indicators with a multiple light source up to 1/2 not functioning" (2.0%), "Stop lamp not working" (1.2%), "Battery(ies) insecure but not likely to fall from carrier" (0.8%) among the Smc Cg's lamps, reflectors and electrical equipment faults.

Brakes

Around 30% of the recorded Smc Cg failures fall in the Brakes section of the MOT inspection manual. Testers recorded "Decelerometer (sp) efficiency less than 50% of the required value" (1.2%), "Flexible brake hoses slightly chafed" (0.8%), "Gradient tester (sp) efficiency below requirements" (0.4%) among the Smc Cg's brakes faults.

Identification of the vehicle

Around 11% of the recorded Smc Cg failures fall in the Identification of the vehicle section of the MOT inspection manual. Testers recorded "Registration plates missing" (1.6%) among the Smc Cg's identification of the vehicle faults.

Top Recorded Smc Cg DVSA MOT Test Statistics & Defect Descriptions

The descriptions below are the exact DVSA failure strings testers recorded most often for the Smc Cg, each with how many of the model's 249 tests it was noted on.

  • "Individual direction indicators with a multiple light source up to 1/2 not functioning" (Minor) — noted on about 5 Smc Cg tests, 2.0% of the model's MOT record.
  • "Registration plates missing" (Major) — noted on about 4 Smc Cg tests, 1.6% of the model's MOT record.
  • "Stop lamp not working" (Major) — noted on about 3 Smc Cg tests, 1.2% of the model's MOT record.
  • "Decelerometer (sp) efficiency less than 50% of the required value" (Major) — noted on about 3 Smc Cg tests, 1.2% of the model's MOT record.
  • "Flexible brake hoses slightly chafed" (Minor) — noted on about 2 Smc Cg tests, 0.8% of the model's MOT record.
  • "Battery(ies) insecure but not likely to fall from carrier" (Minor) — noted on about 2 Smc Cg tests, 0.8% of the model's MOT record.

Best and Worst Smc Cg Model Years by Pass Rate

The strongest Smc Cg model year on record is 2014 (97.4% across 78 tests), and the weakest is 2016 (89.9%). The gap between them is 7.5 points. Years with fewer than 50 recorded tests are excluded, so these are the years with enough MOT history to mean something.

Smc Cg reliability is declining in the DVSA data — the pass rate moves about 3.8 points a year across the most recent model years shown above.

Pre-MOT Inspection Checklist for Smc Cg Owners

These checks follow this Smc Cg's own most-recorded failure strings, starting with what a tester is most likely to flag on a Smc Cg.

  • the lights — “individual direction indicators with a multiple light source up to 1/2 not functioning”

    Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.

  • the number plates — “registration plates missing”

    Check both plates are present, legible and correctly spaced, with the postcode of the supplier and the BS AU 145e mark. A private plate in the wrong style is a fail before the car is even looked at.

  • the brake pipes — “flexible brake hoses slightly chafed”

    Brake pipes run under the car, usually in front of the rear wheels. Flaking or crusty metal is what fails; a light dusting of surface rust does not. Worth asking a garage to look while it is on a ramp.

Derived from the DVSA failure strings testers recorded for the Smc Cg. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
