I think that a lot of people have lost sight of what a pick-up truck is supposed to be designed for. Carrying or pulling heavy loads that often exceed weight of vehicle. Trucks in general have drastically improved in this design but have also made leaps and bounds in the area of creature comfort. My first truck was a 79 Chevrolet K5 Blazer. I loved the thing. It was an offroad beast, but you talk about noise, and vibration and really bad road mannners. Todays trucks have lost offroad capability but are far more car like on the street. This really opened sales to people that drive them daily but never use them for their true intended purpose. If your truck is still too noisy then maybe you should trade it in for a luxury car.
Everyone on this website wants their truck to be a luxury car. It's a truck people. The things you need to worry about are:
Does it have enough power to toe a good sized load?
Can it carry a fair amount in the truck bed?
And finally can it handle itself off road?
Yes, While it seems everything considered, people should realize it's a truck, they also need to compete. And when you have Ford and Toyota producing very capable and incredibly solid products, (I should include the fantastic new Ram) the Silverado really doesn't compare, despite it being the "Motor Trend Truck of the Year." I have personally driven an 07 Silverado. I certainly wasn't disgusted with it, but I was by no means impressed either. I ended up buying an F-150 again and believe I got a much better vehicle... but then again, everyone has different tastes...
To the original reviewer, you probably have a vacuum leak causing your squealing noise as well as your poor fuel economy. Its sounds to me like your dealer is either shady or incompetent in diagnosing you problems. Go to another dealer. Don't just blame GM and say all their trucks are crap because you are having some very MINOR problems with a first year design. Don't get it twisted, I'm not a die-hard GM fan. In fact I work for Hyundai and drive an old Lincoln, but I can't stand to see mis-informed and mis-lead consumers bash a car company because of its sometimes dishonest dealers. In this business you are either a car guy or a crook, it is what it is. Besides, if you wanted a luxury vehicle, you should have bought an Escalade.
I have '06 z16 LS loaded. The interior "noise" is noticeable but not annoying like it is to other posters. It IS a TRUCK with MOST of the comforts of a luxury vehicle. I bought it used at a very good price and low miles. After comparing it to the other mfgs., my personal taste is still with GM. The only problem is that the 6-cd changer will report a false error with my home computer recorded CDs after it has been playing for over an hour. THAT is frustrating! It acts like it is overheating (?)
You're losing air in the tires because they are either not balanced correctly or, and this is most likely it... the truck does not like to stay aligned. My 09 was constantly losing tire pressure. The shop I worked for determined I was 2 degrees out of alignment, which is hardly noticeable, but shifted the weight to the back causing tire pressure issues.
