Tl- the contact owns a 2011 Infiniti Qx56. The contact stated that while operating the vehicle a rattling type noise was present coming from the engine area.

I noticed the vehicle started making a loud whistle noise emanating from the engine during cold start-ups. Approximately 2 weeks later I took it for service at the orlando Infiniti dealership on January 5, 2016. As soon as I described the issue the service advisor and multiple technicians immediately said "is the timing belt. " prior to this vehicle I owned a 2005 Qx56 that I drove for 10 years with over 180, 000 and never had any issues. Now I look online and everywhere I look I find that it is a very common issue with this vehicle. It is so common that the Infiniti dealership has one technician dedicated to working this issue alone. While at the shop I saw at least 5 more Qx56 vehicle in for the same issue. Now I am looking at a repair bill over $4500. I never had any vehicle with 90,000 miles and having this issue. It is way too common and it is a crime that Infiniti has not categorized this issue as a full recall. These are top dollar luxury vehicles!!!.

Problems with the timing belt chain on newer model Infiniti Qx56. Problem of car making whistling noise appeared early after purchase and intermittently thereafter but became prominent in July 2011. Appears to be a recurring problem with this vehicle model. Dealer had to replace the entire engine on the vehicle to address the issue. However, we believe the underlying defect in the timing belt chain will continue to occur and that there is the potential the engine could fail and cause a major accident(s) and/or fatalit(ies).
