Two weeks ago driving 60mph on highway in snow engine light illuminates and lose total power. "reduce power mode" illuminated but engine shut off. We almost got rear ended by a tractor trailer on [xxx]. On side of road for 2 hrs in 20 degree weather waiting on aaa (no shoulder on hway) and motor starts. Take it to garage and get throttle position sensor (tps) code ans stabilitrak/ABS code. We had accidentally hit the onstar button a minute before this and mechanic thought that was related so he cleared code and sent us on our way. For two weeks we were good andit happened again on highway in rain [xxx] this weekend, again in middle of highway. This time car started after five minutes. Took car to dealer and they state the tps needs replacing and front wheel speed sensor broken. There is a gm service bulletin #11273b where gm acknowledges tps issue and covers replacement of tps for 2008-2011 vehicles. Also bulletin pip3089b for bad wiring to tps for 2003-2006 avalanches. Gm denied my service despite the fact that a 2007 tps and throttle body are the same exact part number as the defective one. This is super dangerous and extremely frequent as there are 550 posts alone on [xxx] as well as many reports to [xxx] please assist as they are not standing behind a defective and deadly product as the computer cuts total power right on highway...
