Example complaints

“I starting hearing a grinding noise coming from engine couple of weeks ago. Took it to the Infinity dealership for a diagnostic test. The mechanic stated “ timing chains were found to be stretched and metal was worn.” This is the same issue which prompted the recall of 2011-2013 QX56 models. However, I did not own my vehicle during the recall period.”

NHTSA complaint #11500607, filed 2023-01

“My timing chain was stretched. This is the same problem the Infiniti qx56 had. My QX80 has the same motor and replacement timing chain part. The qx56 was issued a voluntary service campaign for this problem. My chain has not been included. Even though it has the same junk timing chain. Infiniti quoted me a repair price of $4800.”
