CAUSES AND EFFECTS OF FAILURES

Here you will learn more about the possible causes and effects of the most common failures in automotive systems

The highlighted analyses are based on potential issues that may arise in relation to a failure; therefore, they do not constitute definitive analyses regarding maintenance and reliability. For accurate analysis of any issues with your vehicle, please consult an authorized specialized workshop.

The defects were analyzed considering the level of hazard, related to accidents (SAFETY RISK), as well as how a defect may lead to a larger issue or even the total failure of the vehicle system (FAILURE SEVERITY), and the vehicle’s overall disablement.

SAFETY RISK – Assessed at levels 1, 2, and 3:

  1. Low risk. The defect is unlikely to cause an accident. The driver can proceed to the workshop with their vehicle.
  2. Medium risk. The defect may inconvenience the driver’s operation, potentially leading to an accident.
  3. High risk. The defect poses a risk of serious accidents that endanger lives. The driver should contact a towing service.

FAILURE SEVERITY – Evaluated at levels 1, 2, and 3:

  1. Low risk. The defect is unlikely to cause other defects or the disabling of intrinsic systems or the vehicle.
  2. Medium risk. The defect may lead to the defect of other components over time and render systems unusable.
  3. High risk. The defect will certainly render a system and the vehicle unusable over time or instantly
