I bought a 2011 Infiniti M56x 2 years ago. I absolutely love it for the performance of the engine and the interior. Unfortunately it's also come with more than enough problems. I'd owned two Nissan Altimas previously but wanted to upgrade. I travel across Ontario for my career, and have been stranded multiple times because of battery and engine problems. There is a recall on the timing chain which created cylinder misfires in the engine. In mid-January I reached out to Infiniti Canada who are no help. 5 dealerships wouldn't call me back to schedule the work. The one that has is March 6th. I've been stranded without a car since mid-January and Infiniti won't help at all. When you purchase a car of this caliber, you expect excellent customer service. I will be trading it in immediately after the recall is performed. For other reference, read Car & Drivers long term test drive..."Be careful what you wish for" is the title.
