What Year Did Gm Fix The Afm Problem?

In 2011, GM fixed the AFM issues. In the years preceding up to 2011, GM had to make significant modifications to the AFM system to ensure the engine’s functionality. To ensure appropriate lubrication, improvements were made to the AFM’s design, more materials were added to the lubrication system, and the minimum oil level was raised.

In addition, GM had to modify the testing procedures for the AFM system. Before the system was placed in a car, it was tested to ensure that it was functioning properly. All of these modifications were required to address the problems that have plagued the AFM system since 2007.

Once GM had made these modifications to the AFM system, it was implemented in 2011. Since then, the AFM system has been operating without difficulty, providing increased fuel efficiency and engine performance for drivers.
