Lawsuit Filed Against Mazda for Oil Consumption Issue

Dec. 9, 2022

Plaintiff Brian Heinz is the owner of a 2021 Mazda CX-30. 


Dec. 9, 2022—A class action lawsuit against Mazda alleges oil consumption issues, according to Carcomplaints.com.

The lawsuit was filed by plaintiff Brian Heinz of California. He purchased a 2021 Mazda CX-30 in September 2021. According to the lawsuit, his vehicle had a low oil warning light in February 2022 that would periodically switch on and off. 

An oil change and other services were performed on the vehicle in May 2022 at a dealership, but the low engine oil light came back on afterwards. The plaintiff alleges that this oil consumption issue makes his vehicle potentially dangerous to drive and he has to add additional engine oil as a result. 

According to the lawsuit, this issue could impact the following vehicle models: 2021 Mazda3, 2021 Mazda6, 2021 Mazda CX-30, 2021 Mazda CX-5 and the 2021 Mazda CX-9.

According to a technical service bulletin from October 2021, Mazda had not determined a cause for the issue. The bulletin went on to say that owners should not have to pay for the additional oil or repairs because the vehicles were technically still under warranty.

Mazda encouraged dealerships to "explain the oil consumption problems to customers and how it had been confirmed oil leakage into the combustion chamber would not cause immediate engine damage," according to Carcomplaints.com.
