I am on the fence on this one, I am leaning towards the issue is bigger than we think. How many trucks are out there currently having this issue but the owners are not aware? In most cases you have to intentionally listen for the noise and I don't think most people do this. I noticed last week my truck was making a tapping noise under light part throttle conditions. I just so happened to have the windows down, radio off, and driving next to a barrier and could barely hear it. Under normal driving conditions my truck drives fine and I cannot pick up on any additional noises. However, now that I am listening for it I can definitely hear it while in park and revving the motor, especially if I max out the high idle. I am sure there are numerous trucks on the road that sound just like mine but the owners are unaware.
At this point I am going to drive mine like normal and see if the noise gets louder. This prolly isn't the best strategy but reading all the dealer horror stories I don't want to deal with that right now. If or should I say when my truck gets louder I will take it in but for now its business as usual. What sucks is in the past I would always look for a reason to get a new truck but I honestly don't want a different truck, I only want this one to work as advertised.
