The number speaks for its self – 89%. This is the percentage of 2010 vehicles now equipped with a maintenance reminder. The most basic function this maintenance reminder serves is to remind the driver when to do an oil change. These systems have been in place since 1982 but it has only been until recently that they have been more widely accepted in the auto sector. Now I am finding more manufacturers are carrying this basic system while the companies like BMW are refining theirs. BMW’s system can now tell you when you are due in for brakes, filter replacements, and other major fluid changes.
