My qx50 is currently back in the shop. So far Ive spent about $12,000 on engine and transmission repairs and the NHTSA dsnt seem to be doing anything about it. Now it needs a new ignition coil for another $1,000. Im just at a loss for words!! Im attaching the Review of services that was conducted earlier this month, when my Infiniti was in the shop and the diagnostic codes that came up when I had to have the vehicle towed there, less than a week later.
