VEHICLE WAS CLIMBING A RESIDENTIAL STREET WITH A GRADUAL INCLINE IN SNOW APPROXIMATELY 3 INCHES OF FRESH POWDER WITH NO ICE UNDERNEATH. VEHICLE HAD ONLY 3,150 MILES ON THE ODOMETER AND THE TIRES WERE STOCK ALL SEASON YOKOHAMA WITH A GOOD MUD/TREAD RATING. THE VEHICLE WAS CLIMBING THE HILL VERY WELL UNTIL AT THE CREST A CHECK ENGINE LIGHT AND AWD LIGHT ILLUMINATED AND THE VEHICLE STALLED. THE TIRES FAILED TO CLEAN THE SNOW PROPERLY AND I SLID BACK INTO A GUARDRAIL FOR APPROXIMATELY 500 FEET AND THERE WAS COSMETIC DAMAGE TO THE VEHICLE AS WELL AS THE RIGHT WHEEL WAS BENT. DEALERSHIP WHERE I TRADED THE VEHICLE INTO HAD 2 OTHER CUSTOMERS TRADE THEIR 2018 CROSSTREKS DUE TO POOR AWD SYSTEM AND VERY DANGEROUS ALL SEASON TIRES.
