2021 Titan Pro 4x
Bought a 21 Pro 4x back in March. I've noticed that I get a brief, nasty little vibration, almost like a grinding noise, with hard acceleration. I feel like it's worse when I have the climate control system on. Yes, I realize that pretty much every car or truck out there runs worse when the A/C is on. I've brought my truck into the dealer twice to have them check it out and see if they can find something wrong but both times they came up with nothing. It happens mostly when starting from a lower gear (or slower speed) and once the engine gets to about 3,500 RPM. When I'm riding down the highway and floor it and the engine gets up to ~3500 RPM, it doesn't do it. The guys at the dealership said they test drove 3 other new Pro 4x's on the lot and said they all do the same thing. I've seen the TSB about the fan coupler vibrating at 3500 RPM. I mentioned this to the technician at the dealership but he said this was a problem with previous years and didn't think it was the problem with mine. I love everything about this truck except for this damn vibration! I just feel like it runs rough and it's starting to really ruin the truck for me. Anyway, I'd love to know if any of you are experiencing this with your Titans. I guess it would make me feel better if it really was common to all new Titans and not just mine! Thanks!
