Infiniti electrical problems

Owners have filed 1,091 complaints with NHTSA about the electrical system on Infiniti vehicles — 11% of everything reported about the brand, across 37 models. The model that accounts for most of them is the Infiniti G35, worst in 2003.

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.
