“I been having problems with oil consumption in between oil changes,I am concerned with the potential for damage to other engine systems aside from the reported issue with the gasket stem seals. I been taking my car to the dealership and I been told they don’t have a solution and they don’t know how to fix it. This is a new car!!!”
NHTSA complaint #11491628, filed 2022-10“Twice had low oil warning lamp appear. First time in July 2023, 2nd time in June 2024. Both times oil has just been changed 2-3 months prior. Saw articles that there was a recent lawsuit, which is why I am filling complaint as well. Not for lawsuit, but for repairs so this does not occur again.”
