Started car in the morning and it started misfiring very badly. Flashing check engine light. Immediately pulled over and shut engine off. Had it towed to my shop I use they hooked it up to computer and it was diagnosed as a loose timing chain. Basically timing chain replacement This is rediculous only has 129k miles. They claim timing chain and components are good til 300k with regular maintenance. This suv since new has had synthetic mobile 1 oil changed every 3500 miles. There was a voluntary recall on this issue. Why was it ever taken down Now Iâm paying the car payment on a car I cannot drive. Till I spend $5000 to have all that replaced

Our Infiniti QX56 started misfiring and shaking when driving. We took it in to the Infiniti dealership and was informed it is a bad timing chain. Upon research, we realized there was a recall for this issue on 2013 Infiniti QX56 models just like ours. However, our VIN did not show on the recall list. Our car has been meticulously maintained. Our research revealed that timing chains in well maintained cars should last up to 300,000 miles. Our car has 105,000 miles. We feel this repair should be covered by Infiniti. We did not pay for a luxury car to have this type of issue. The car is undrivable due to safety concerns and we would like this addressed immediately.

The timing chain needs to be replaced on my vehicle with under 80,000 miles. Researching the issue i found that this is a very common problem with this specific engine. This is an $80,000+ car brand new and it did not last 80,000 miles. This is an obvious part malfunction due to the design of the vehicle. Infiniti should do something. It is a costly repair.

While my wife was driving our QX56 during normal conditions at approximately 40MPH, QX56 begun to swerve repeatedly left to right in a dangerous manner and she had to apply brakes rapidly. Looking under the vehicle, the lower control arm was badly cracked and the cause of the swerving. I towed to my local shop (not Infiniti dealership) for repair and they confirmed the right control arm was cracked. They stated the left control arm was also severely rusted / damaged and wasn't too far from cracking either. Fortunately, my wife was only going 40mph and was able to control the swerving. If going 70 or 75MPH on the highway, I'm not sure that would have been possible. Pictures are attached,…
