Mercury transmission problems

Owners have filed 2,986 complaints with NHTSA about the transmission on Mercury vehicles — 10% of everything reported about the brand, across 20 models. The model that accounts for most of them is the Mercury Sable, worst in 1991.

These are raw counts. A model that sold in millions appears near the top for that reason alone — the grade never compares one model with another.
