  1. Hi everyone, Here is my story : I bought a brand new GMC SIERRA 2015 ,5.3 l engine "ECOTECK",6 speed ,3,42 ratio, in November 2015 .,an sle trim,Kodiak edition and I was very happy with it for a couple of weeks until I realized there are some spots in the paint on the hood and roof .I went back to the dealership and they offer to paint it(the roof and the hood)and they did a good job I would say. But this was the beginning of my nightmare : After a few months the BCM (body control module ) ceased to work ,the car start shifting the gears abnormally and I lost the front lights on my way back from the cottage in a night at 300 km away from my home .imagine how i drove back to home from the middle of nowhere ,only with the fog lights !!!but the dealer said they fix the problem changing the BCM Then the car start burning more gas then it use to .I use to maintain a very good gas economy around 11.3 to 12 liter per 100 km on hwy and around 14 mixt on the city and after they change the BCM the gas consumption gradually increased and now after 2 years and about 60000 km I can`t go lower than 14.6 on hwy (100-110 km/h speed) and 17,6 mixt in the city. Nobody could fix it and of course they always said everything is in parameters and looks good After about a year my transmission ceased in a middle of a hwy right after they replaced the hydraulic pump inside the transmission !!!! can you believe this??? If everything were good why did they change the pump inside the transmission, and this after I complaint about the hard and kicking shifting I have when I press the gas pedal in a slow driving in a traffic hwy (that time you let the car slowly move without pushing the gas pedal then after the car in front of you go and you try to keep up with the traffic ) .So they rebuild a one year old new transmission but the kick shifting they never fix it because they never admit officially is there, even everybody feel it and they said is a KIND of normal!!! Then after my infotainment system freezes up and blocked then they had to replace it .the whole radio unit with the GPS and all After another few months the differential start clinking and roaring and they rebuilt that too and now is really noisy when is cold and if I drive it in autotrack mode I barely hear the music at the radio inside the truck(the mechanics at the dealer ship always tell me that I`m not suppose to drive in auto mode !!!!! because it wears the transmission components !!!! well why the heck did I pay extra 5000 $ for this feature if I`m not suppose to use it ????) just dumb I guess !! So now I`m driving this 53000$ piece of steel ,burning my money on gas ,feeling every gear shift in the transmission kicking my butt when I`m decelerate for the next 5 years because I did the mistake of my life to buy this GM piece of ...steal for 7 YEARS. DUMB AGAIN! Well if this is the GM PRECISION which the GM ENGINEERS CLAIM IT IN THOSE advertises on tv I have to say they got the wrong word they should say GM UNRELIABILITY !!!! It is probably a bad batch what I got ,A LEMON let`s face it, but nobody whatsoever officially admit it in CANADA (once I called the GM North America in the states, they check my VIN and they said there are way to many problems with this truck in such a short time and something has to be done with it ,they transfer me to the Canadian GM customer service(ambassadors!!!!) and here we are again ...nothings wrong again all the reports are in parameters go to the dealership bla,bla ,bla ,zero,zero ,zero) and everyone try to get rid of it by saying everything works in parameters PS: I FORGOT TO MENTION THAT WHEN THE TRANSMISSION CEASED AFTER 5 KM AWAY AFTER I PICKED IT UP FROM THE DEALERSHIP , I CALLED THEM AND THE SHOP FOREMAN AND THE TRANSMISSION SPECIALIST CAME RIGHT AWAY ,THEY PLUGGED IN THEIR LAPTOPS AND THEY COULD NOT FIND ANY ERROR CODE ON THE TRUCK ,SO THEY SIT ON MY TRUCK REV THE ENGINE SHIFTED ON DRIVE MODE AND NOTHING HAPPENED THE TRUCK DIDN'T MOVE THE MOTOR REVVING AND THEY ASKING EACH OTHER WHY THERE ARE NO FAULTY CODES SHOWING UP !!!!!! MY QUESTION IS ,ONLY SOME OVERSEAS CAR MAKERS ARE CHEATING WITH THE SOFTWARES OR EVERYONE IN NORTH AMERICA DO ? and what I did wrong in this world to pay this price for this piece of "steal"? If anyone faces this problems or some of them please give me a shout ,maybe I`m not the only guy with such a bad luck to pick a pickup truck
