The Chevrolet Gmc Blazer has an overall MOT pass rate of 76.0% across 641 real MOT tests — comfortably above the UK average, which puts it among the more reliable models on UK roads.
The most common problems on the Chevrolet Gmc Blazer are brake pipe excessively corroded (17 recorded failures), suspension has excessive play in a lower suspension ball joint (14), and parking brake: efficiency below requirements (14). These are the faults most likely to cause an MOT failure on this model, so check for them carefully on any test drive or pre-purchase inspection. Many are wear-and-tear items that can be budgeted for, but a car that's already failing on multiple fronts may signal neglected maintenance.
A typical Chevrolet Gmc Blazer owner drives around 1,532 miles per year. If the car you're looking at is significantly above this, expect more wear on suspension, brakes and tyres. If it's well below, the vehicle may have been sitting unused — check for perished rubber, corroded discs and stale fluids.
In terms of longevity, most Chevrolet Gmc Blazer models stay on UK roads for around 41 years — a strong showing that suggests solid build quality and readily available parts. If you're buying one that's already approaching that window, the data suggests it has plenty of life left provided it's been maintained.
Before committing to a purchase, we recommend running a full vehicle history check on the specific car. This will reveal any outstanding finance, stolen markers, write-off history and mileage discrepancies that the seller may not disclose — and that the MOT data alone can't tell you.
