Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Alfa romeo USA is in my opinion hiding a constant problem they have with stelvios. The oil turbo line has a faulty oring and leaks oil onto engine which causes smoke that can not be healthy to breathe in. I have talked to severa alfa dealers in service depts and they confirm to me that they have fixed numerous stelvios with this problem. This should be a national recall for repair at no cost to the consumer. I tusually happens close to warranties expiration near 50k miles or shortly after.”
