Where they fail
Share of tests with at least one failure in each area, against cars of the same age.
A test can fail in more than one area. Failures fixed during the test are included.
Most common failures
The 10 defects that failed Proton Persona tests most often, as a share of all tests.
| Failure | Tests | Cars the same age | vs same age | Marked dangerous |
|---|---|---|---|---|
| Catalyst emissions: Lambda reading after 2nd fast idle outside specified limits Emissions and leaks | 6.7% | 1.8% | 3.7× | 0.0% |
| Position lamp: not working Lights and electrics | 6.7% | 3.8% | 1.8× | 0.0% |
| Component mounting prescribed areas: prescribed area excessively corroded significantly reducing structural strength Suspension | 5.8% | 3.2% | 1.8× | 0.0% |
| Horn: not working Lights and electrics | 5.8% | 1.1% | 5.3× | 0.0% |
| Headlamp aim: too low Lights and electrics | 4.8% | 1.7% | 2.8× | 0.0% |
| Wipers: does not clear the windscreen effectively Visibility (wipers, glass, mirrors) | 4.8% | 2.7% | 1.8× | 0.0% |
| Rbt (sp): efficiency below requirements Brakes | 3.8% | 2.1% | 1.8× | 0.0% |
| Brake pads: less than 1.5 mm thick Brakes Dangerous | 2.9% | 1.1% | 2.6× | 100.0% |
| Catalyst emissions: carbon monoxide content after 2nd fast idle exceeds manufacturer's specified limits Emissions and leaks | 2.9% | 1.3% | 2.2× | 0.0% |
| Parking brake performance: inoperative on one side Brakes | 2.9% | 0.9% | 3.2× | 0.0% |
“vs same age” compares this model with cars of the same age: 2.0× means twice as often. “Marked dangerous” is how often the tester recorded that failure as dangerous.
