This 1999 Blazer is notably unreliable for its age, with a first-time MOT pass rate of just 64.3% — well below the UK average of 80%. Nearly 3 in 10 of these vehicles have been flagged with dangerous defects, which is a serious concern and suggests significant safety risks that buyers need to investigate thoroughly on any used example.

At around 86,000 miles median, these Blazers are not heavily worn for their age, yet they're still averaging over 3 failures and 13 advisories per test, pointing to deteriorating component condition rather than exceptional mileage abuse. Before committing to purchase, have a pre-buy inspection done by a mechanic familiar with American trucks, focusing especially on suspension, brakes, and structural rust — the high advisory count suggests these systems are wearing out unpredictably.
