Service Technicians Name Top 10 Damaging Mistakes Drivers Make

Auto Technicians

CarMD reached out to its ASE-certified master tech committee to confirm the top 10 most damaging mistakes drivers make. CarMD thinks this information will help consumers save money in the long run and plan better as they care for what is often their second largest purchase.

1. Putting off recommended/scheduled maintenance;
2. Ignoring the check engine light;
3. Not changing the oil, or not having it changed on time;
4. Not checking tire pressures;
5. Neglecting coolant, brake, transmission and other fluid services;
6. Continuing to drive when the vehicle is overheating;
7. Not changing fuel and air filters;
8. Having unqualified shops service their vehicle;
9. Using generic aftermarket parts instead of OEM-quality parts; and
10. Trying to service their own high-tech vehicle.

Technicians say failing to change oil has been the single most damaging car maintenance item that customers neglect. “Camshaft actuators can freeze when restricted by dirty oil, and a faulty camshaft actuator can in turn cause the check engine light to illuminate, resulting in complete engine failure if ignored for too long,” the report said.
