My Sonoma never even got 19 on a good day. It only gets 17 on the highway. I drive 50 miles round trip highway miles to work every day. I have had it for 6 months and I have to sell it because of the poor mpg.
I have a roar in the engine from time to time that sounds like I have shifted to 4 WD when it is definitely in 2WD. Taken in to the dealer and he can never hear that sound. Does not do it all the time but when it does it sounds like the engine is going to come out from under the hood. Been in the shop 5x with shifting problems, shims, water in headlamp, wind noise both front doors, very poor gas mileage empty load or pulling trailor. Would not recommend this truck to anyone.Center console is too small and tight up front. backseat leg area too small. Just me and the dog and still not enough room.Bummer cruise control. Cheap, would have paid the difference for a good cruise controller.
Vehicle needs aproximately 50 more horse power to be a good work truck. It suffers from a blind spot over the right rear corner due to the location and size of the c pillar and rear seat headrests. The fit and finish of the sheet metal (out of Linden NJ) was less than stellar. Warranty repairs to AC compressor, transfer case electric shift solenoid and air distribution system vacuum motors required
I like my truck and plan on keeping it for a long time. The 4.3 has plenty of power for me although it is a bit thirsty. I haven't had any reliability issues at all. My complaints come from GM's classic little things like, I'm on my 3rd radio and this one is messing up. (out of warranty now) Wind noise from drivers door weather stripping. (that the dealer couldn't hear when it was under warranty) Intermittent wiper switch slowly faded and is now on a mood basis. Noise from the front right wheel well when I turn left and accelerate hard. Scared to go to the dealer on this one!! Only other complaint is gas milage. Tows plenty, but hauls nothing!
