Consumer Description

Excessive intermittent Engine vibration at 10 mph to 40 mph at very light load, very light throttle. If a very light throttle Is applied or removed the vibration seems to go away. In light traffic at low speed the vibration is of concern as to the damages it may further cause. On 11/19/2024 Boucher Mazda charged me to perform PCM and TCM updates which did not correct the problem. On 12/11/2024 Russ Darrow Mazda of Greenfield Wi, thought a motor mount KN-39-040 should be replaced. $540.28 later, the problem is worse. I believe the problem is caused by the CYLINDER DEACTIVATION issue Identified by Recall 3719F which I was never notified. This is a safety issue, because I don’t know when the engine is to fail or stall or what the damages will be. I pay a large fee for Diagnosing only to get “LIP” Service.
