Just my 2cents; It wasn't the engine that was the problem, really. It was more the drivers. Rotaries need to be redlined (once warmed up of course) to clean the carbon out, and work "properly". This being the case, the fact of the matter is the VAST majority (like 98%) of engines replaced were from automatic cars. Most of these owners simply did not drive their cars the way the cars needed to be driven. The major cause for the recall was flooding due to carbon build up, and some issues with the engine management system, as opposed to the engines' design. Mazda has since modified some of these areas, and apparently it is nearly impossible to flood the updated cars. They've also extended the warranties on all 04-08 cars to 8 years/100,000 miles![]()
