    Other major engine problem

    "Mazda sold five different models with a 2.5L Turbo that had faulty valve stem seals that resulted in excessive oil consumption. After many months of having to add oil between changes, Mazda finally developed a fix. Initially it was very difficult to get the repair. My service manager argued that all turbos do that and I ultimately had to engage with a Mazda Customer Mediation Specialist who had my car shipped to a dealer over 200 miles away because the dealership in Spokane was uncooperative and appeared to lack the skills and equipment to make the repair. I also filed a class action lawsuit against Mazda and the suit is in the final stages of being accepted by all parties and the court. The details about the suit can be found on the official settlement page at this URL, or you can search Guthrie, et al v. Mazda Motor of America, Inc. https://www.mazdavalvestemsealsettlement.com/"
