I have owned a 2015 tahoe LTZ, traded for a 2016 suburban LTZ because of growing family. I also have a 2015 Silverado LTZ Z71.
I have never had a interior noise issue. These trucks are super quiet, way quieter than the GMT900 trucks. I think the sound suppression has added to People’s perception of normal noise. My pickup is so quiet that I actually hear the whine and shifting in my transmission. That’s all I hear, lots of white noise and some gear whine. Could never hear this before cause I would hear wind noise, tire noise and engine noise over everything else.
Long story short, neither my tahoe or suburban have caused noise problems. 100% believe these are the best large SUV’s on the market. The extra sound deadening, carpeted fenders, sound deadening laminated glass, and higher end soft interior touches have deadened most normal sounds, and I think, as a result, we have become more susceptible to certain lower frequency noises that could not be hard over all the other noises on previous models. I have heard some minor resonance in my Burban when at low steady speeds in 4cyl mode. Or at cruising speeds with a tailwind. The exhaust obviously has more vibration in 4cyl mode vs 8cyl mode. But I understand it and expect it. I would not ever consider it excessive, or causing sickness like some claim. I actually welcome a slight drone from my exhaust - that means my engine is under light load, and I’m getting 20+ mpg!
Side note: I put a diablo tune mpg tune reprogram in my suburban and it has woken the ***** up. Much more throttle response. I drive monthly out of state for Med treatment. 1,100 miles round trip. I constantly get 20-24 mpg overall on the trip. With a good programmer, these mammoth cars get the same mpg as a midsize suv. Oh and I don’t drive slow. 85 mpg in my state and 80 in the neighboring state.
Honestly I cannot say anything bad. About these SUV’s. HUGE capacity and I get same mpg as a smaller traverse on highway trips. Difference is I have two Blu-ray screens and my kids can walk around inside to get stuff out of bags or get me a drink out of the cooler.
Cheers!
