1 Crankcase (pcv) problem of the 2016 Mazda CX-5

Failure Date: 10/16/2024

The car engine is eating oil. There were no warning lights on the dash to indicate this. I happened to check the oil and it was 3 quarts low. This could have caused the engine to malfunction while driving if not caught in time. This started around 70k miles. Coffmans service center in warminster, PA has confirmed the car was spraying oil on [xxx] and performed a clean combustion chamber with iridium spark plugs, replaced intake manifold gaskets and pcv valve, and ow-20 oil and new filter. I contacted the manufacturer on [xxx] case # [xxx] and it was dismissed. I did read online that this Mazda car has had a problem with eating oil around the 70k mile mark. The problem is still occurring. I read that there was a class action lawsuit against Mazda. [xxx] et al v. Oil Mazda motor of America. However, the class action lawsuit doesn't include the 2016. I think it starts around 2021. I uploaded the receipt for the repair on an older complaint. The complaint number for that one 11627409. Currently there are over 450 complaints on the 2016 Mazda cx5 on the NHTSA website. Can we get a recall on this? information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
