A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).
Even more advanced devices allow users to reset engine DTC codes, effectively turning off engine lights in the dashboard; however, resetting the codes does not address the underlying issues and can in worst-case scenarios even lead to engine breakage where the source issue is serious and left unattended for long periods.
Intermittent faults are notoriously difficult to identify and repair ("troubleshoot") because each individual factor does not create the problem alone, so the factors can only be identified while the malfunction is actually occurring. The person capable of identifying and solving the problem is seldom the usual operator.
The GM Instrument Cluster Settlement was a 2008 class action settlement awarded to owners of certain General Motors vehicles with allegedly defective speedometers.The settlement allows the owner or lessee to get their instrument cluster replaced under the terms of a special coverage adjustment to their factory standard warranty.

Non-stick coatings, reduction of contact area, and increased awareness mitigate the problem in contemporary systems. [9] Particles migrating in the system and blocking their movements. Conductive particles may short out circuits like electrostatic actuators. Wear damages the surfaces and releases debris that can be a source of particle ...
Overhead power lines are easiest to diagnose since the problem is usually obvious, e.g., a tree has fallen across the line, or a utility pole is broken and the conductors are lying on the ground. Locating faults in a cable system can be done either with the circuit de-energized, or in some cases, with the circuit under power.
On August 28, 2009, SquareTrade published a report saying that "early indications point to the RROD problem abating in 2009", projecting that 1-year failure rates with the release of the Jasper chipsets might be below 4%, with actual fail rates for RROD problems at slightly above 1% in Q109, and total failure rates for all hardware problems at ...
