'bout what I'd expect from GM

....

Silly JUF, these trucks were not designed to go up hills.

You forgot to say, thank you GM

Hiway safety commission says they have to be there,doesn't specify they have to work. :>(

These are working as designed. Did you find the RAINEX in the glove box?

At least when you get yours started you can drive it. Several times now mine starts but drive does not engage. Have to run through the gears 3-4 times before it will grab and go.

You can buy all the extended warranties you want. GM will just say that's the way it is supposed to be, and refuse to fix it. Then one of these GM monitors here will get involved and pretend to do something beside ask for your vin and dealer

Took it to the Toyota dealer and showed it what it will be replaced with.

I know, The back door I opened it just kept pouring out not a drip but a constant stream for about a minute. My wife opened the front door to look for some thing and it came out the whole time she was in the truck and then she had to wait to shut the door because it was still streaming out.

Today I opened the passenger side doors and let about a quart of water between them drain out of the weep holes under the door. Thanks again GM

I kicked it several times. Low battery screen came on and would not start. Only 2 months old,Thanks again GM

I have walked by it grabbed my hair and screamed WHY,WHY,WHY, then got in a car I am not so disappointed with.

Low battery warning in small screen on dash. Did not want to start a thread but is any one seeing this (saw) this

At 0 with the truck off.Past that I don't want to talk about it

at least it is small and mostly un noticeable. the 14 subaru outback system looks like the thing at the bowling alley that projects the score on the ceiling in front of you,it's huge.

A tonneau can help improve MPG Mythbusters Testing I always take Mythbusters episodes with a grain of salt. How many different model and configuration types did they test? What was the weight of the tonneau used.... Mythbusters episode reference:http://kwc.org/mythbusters/2006/12/episode_64_more_myths_revisite.html Their results actually got the same MPG with tailgate up compared to with tonneau cover. Now account for the weight of the tonneau cover being about 100 lbs and you actually had better aerodynamics but that was countered by the weight of the cover. Effect on MPG will also depend on the steadiness of your speed when adding weight - lots of stop and go acceleration will mean greater effect of added weight. Go with a lighter tonneau like lazerlite aluminum (48 lbs) or an ABS cover (60 lbs) and you will not have so much extra weight to haul around and should get better gas mileage. SAE Testing An example of a good SCIENTIFIC test was done by the Society of Automotive and Aerospace Engineers (SAE): http://ecow.engr.wisc.edu/cgi-bin/getbig/me/363/ghandhi1/pickup.pdf Their testing shows that other variables make a difference such as crosswind and bed length. For their testing of pre-2004 model F-150s they found: 1. In most cases a partial box cover (at the rear) or full tonneau gave the best aerodynamics. 2. For the 8' bed standard cab trucks the tailgate down but not removed gave better aerodynamics than with tailgate up. Tailgate off gave better or worse depending on how much crosswind compared to speed. Full tonneau gave the least drag in all conditions (best for MPG). Mesh gate gave the highest drag in all conditions (worst for MPG). 3. For the 6.5' bed super/crew cab trucks the tailgate up gave better aerodynamics than down or off (like Mythbuster results but opposite of 8' bed results). Tonneau covers gave the least drag in all conditions with a partial cover slightly better than a full cover (best for MPG). Tailgate off gave the highest drag (worst MPG). If you look at the flow models you can see that the difference in Cd occurs after the cab, so you could extrapolate that the bed length difference will be the decider in what method you should go with. The GMC and Toyota tested also support this conclusion with their 6.5' bed trucks having similar results to the Ford 6.5' beds. (Tailgate up is better than tailgate down) In all cases, a tonneau lowers drag...but you have to account for the weight of the tonneau possibly having a negative effect on MPG. Lesson: if you want improve aerodynamics and lower MPG with a tonneau, pick the lightest available. SEMA Testing Here is more scientific testing by SEMA showing that tonneaus improve aerodynamics: http://www.trucktestdigest.com/PDFfiles/SEMATonneauStudy2007.pdf Summary of some of their results: 1. Hard tonneaus did better than soft in general with 6.5% or better drag reduction (hard covers) compared to 5% drag reduction (soft covers) at highway speeds. 2. Reduced drag primarily occurs at above 40 mph and the benefit increases up to 65 mph where it levels off. 3. They also mention that the weight of heavy fiberglass covers can negate benefits. SnugTop manufacturer testing Yes, I am including a link to a manufacturer's tests. http://www.snugtop.com/gas_savings_test.php Their tests show an improvement of MPG with fiberglass tonneaus. Of note, they did their test with cruise control on which would help minimize the effect of additional weight of the cover.

With what I'm getting, it should be called fuel footage

My new 5.3 is about 16.8 I was happy when I broke 17.1 on a 50 mile stretch of hiway with the cruise on.

Sitting in stop and go traffic today, after driving about 60 miles. Every time I started to move and went a few car lengths and stopped there was the loud thunk. as mentioned before it sounded like a bowling ball hitting the tail gate then the front of the bed. put up with this crap for about 8 miles. Please post if you ever find out what this is,only 550 miles on AT SLT
