This class action concerns a defect in certain 2021 vehicles made by Mazda Motor of America, Inc. that causes them to consume excessive amounts of oil. The complaint alleges that the valve stem seals are defective and let oil leak into the combustion chamber, causing them to consume too much oil, violating emissions standards, and causing damage to emissions components and engines.
The class for this action is all persons or entities in the US who are current or former owners or lessees whose vehicles are subject to Technical Service Bulletin (TSB) 01—12/21:
- 2021 Mazda3 (Japan built 2.5T) with VINS lower than JM1BP******403639 (produced before September 14, 2021)
- 2021 Mazda6 (2.5T) with VINS lower than JM1GL******618910 (produced before September 15, 2021)
- 2021 CX-30 (2.5T)
- 2021 CX-5 (2.5T) with VINS lower than JM3KF******472325 (produced before September 14, 2021)
- 2021 CX-9 (2.5T) with VINS lower than JM3TC******541071 (produced before September 14, 2021)
In addition to this class of plaintiffs, the complaint also asks for the certification of a class of defendants, the Mazda dealerships that the complaint claims are “conspiring with Mazda to hide and conceal a known, dangerous defect.”
What is the evidence of this conspiracy? The complaint quotes a Mazda TSB as saying that the dealer should explain the following to the customer: “A small amount of the engine oil may be leaking into the combustion chamber, causing the oil consumption. Mazda has confirmed this oil leakage … will not cause any immediate engine damage and the vehicle may be safely driven. The warning message and Check Engine light will go off by topping off the engine oil.”
The TSB also promises that “as soon as Mazda identifies the root cause, a complete repair procedure will be announced” and that until then, Mazda will “top off or replace the engine oil at no charge…”
But the complaint alleges that the defect does pose a safety hazard—to the environment, to those in and around the vehicle, and to the vehicle itself, because it generates “prohibited, non-disclosed carbon emissions,” keeps the engine from maintaining the proper level of oil, causes it to consume an unpredictable amount of oil, and “can result in engine failure as well as damage to the vehicles’ emissions components including … catalytic converters.” Engine failure can occur while the vehicles are in motion, causing a risk of accidents or injury.
Dealerships conceal the problem when they sell the vehicles, the complaint alleges, and then “spin it” as required by the TSB when the owner or lessee comes back with low oil.
The complaint claims that Mazda has known about the defect for a long time but has been unwilling or unable to provide the necessary fix for it.
