WHEN DRIVING MY 2018 SUBARU WRX PREMIUM IN THE HEAT WITH THE A/C ON IT IS CAUSING EXTREME DRIVING CONDITIONS WITH THE CAR STUTTERING CAUSING FLUCTUATION IN SPEED WITH THE CAR DRAGGING THEN PROPELLING DRAMATICALLY DUE TO THE TURBO ENGAGING. THE ERRATIC CHANGE IN THE PERFORMANCE OF THE CAR IS NOT NORMAL AND IS CAUSE FOR ATTENTION FROM THE MANUFACTURER. I WAS DRIVING ON THE FREEWAY AND THIS PULLED SUCH AN EXTREME DRAIN ON THE CARS ELECTRICAL SYSTEM AND COOLING SYSTEM IT ALMOST MADE MY CAR OVERHEAT IN THE MIDDLE OF FAST MOVING TRAFFIC. MY CAR IS WELL MAINTAINED AND DRIVEN RESPONSIBLY. I HAD MY FAMILY IN THE CAR AND THIS COULD HAVE CAUSED A TRAGGIC SITUATION AS THE FREEWAYS HERE IN CALIFORNIA ARE VERY UNFORGIVING.

Crash reported

IN JANUARY 2019 AROUND 10PM PST MY 2018 SUBARU WRX EXPERIENCED A SERIOUS MALFUNCTION. AT THE TIME OF THIS INCIENT I WAS IN A SUCLUDED, WOODED AREA WITHOUT CELLPHONE SERVICE, AS WELL AS BEING ATLEAST 30MINUTES TO THE NEAREST STORE. THIS COULD HAVE BEEN DEADLY. I WAS GOING DOWN A HILL AT 35MPH, IT WAS VERY RAINY AND DIFFICULT TO SEE. AT THE BOTTOM OF THIS HILL WAS A SHARP RIGHT TURN, AT THIS TIME THE SAFETY SYSTEM ACTIVED TAKING OVER ALL CONTROL OF THE VEHICLE. THIS CAUSED STEERING TO LOCK UP, TURNING TO THE FAR LEFT. AT THE RIGHT WAS A 15-20FOOT DROP INTO A LAKE. THE TURN I WAS SUPPOSED TO TAKE WAS A SHARP RIGHT. STILL UNABLE REGAIN CONTROL AND WAS DRIVING STRAIGHT TOWARDS THE FAST APPROACHING LAKE. SHORTLY BEFORE DROPOFF I WAS ABLE TO FORCE THE STERRING WHEEL TO THE RIGHT. BUT STEERING AGAIN LOCKED UP AND FORCED ME TO THE FAR RIGHT. OFF THE ROAD TO THE RIGHT WAS HEAVLY WOODED. NAROWLY ABLE TO REGAIN CONTROL OF STERRING I CRASHED THROUGH BUSHES. CAUSING MINOR DAMAGE TO THE FOLLOWING; PASSENGER SIDE MIRROR, SCRATCHES TO WHOLE PASSENGER SIDE, DEEP DENT ON LOWER REAR DOOR AND QUARTER PANEL. REAR PASSENGER TIRE COLLIDED WITH A TREE STUMP WITH IMPACT AT 35MPH STOPPING THE CAR INSTANTLY. TIRE WAS SEPARATED FROM THE RIM BY A TREE BRANCH, LOWER CONTROL ARM WAS BENT AND CRACKED, ENTIRE REAR DRIVE AXLE WAS PUSH TO THE RIGHT CAUSEING ALIGNMENT OF THE DRIVER SIDE REAR TIRE TO BE PUSHED OUT. THE AIRBAGS DID NOT DEPLOY AND I HIT MY HEAD ON THE DRIVER'S SIDE WINDOW. THE CAR WAS 100% UNDRIVABLE TIRE WOULDN'T MOVE. TAKING DAMAGE TIRE OFF AND PUTTING ON DONUGT TOOK OVER AN HOUR, I COULDN'T GET THE DAMAGED TIRE OFF. A LOT MORE TO THIS AS WELL. I HAVE COMPLAINED ABOUT THIS ISSUE MANY TIMES AND DEALERSHIP DID NOTHING. I AM SCARED OF THIS CAR AND WILL NEVER OWN A SUBARU AGAIN. THIS IS ONE OF DOZENS OF ISSUES I HAVE WITH THIS CAR.

AT THE TIME OF THIS INCIENT I WAS IN A SECLUDED, WOODED AREA WITHOUT CELLPHONE SERVICE, AS WELL AS BEING AT LEAST 30MINUTES TO THE NEAREST STORE. THIS COULD HAVE BEEN DEADLY.

STILL UNABLE TO REGAIN CONTROL I WAS DRIVING STRAIGHT INTO THE FAST APPROACHING LAKE. SHORTLY BEFORE THE ENDGE OF THE ROAD I WAS ABLE TO FORCE THE VEHICLE TO THE RIGHT. AGAIN STEERING LOCKED UP, NOW FORCING ME FAR RIGHT. AT THE RIGHT WAS DENSE TREES, BUSHES, AND SHRUBS. NARROWLY ABLE TO REGAIN CONTROL BEFORE GOING HEAD-ON INTO A TREE, I FORCED THE STEERING WHEEL BACK TO THE LEFT. I ENDED UP STRIKING SOME BUSHES AND A TREE STUMP. CAUSING MINOR DAMAGE TO THE PASSENGER SIDE MIRROR, SCRATCHES TO BOTH PASSENGER DOORS, AND A DEEP DENT ON THE LOWER REAR DOOR AND QUARTER PANNEL. THIS IS WHEN THE REAR PASSENGER TIRE COLLIDED WITH A TREE STUMP, TAKING THE 35MPH BRUNT IMPACT THAT STOPPED THE CAR INSTANTLY. THE TIRE WAS SEPARATED FROM THE RIM BY A TREE BRANCH, THE LOWER CONTROL ARM WAS BENT AND CRACKED, THE ENTIRE REAR DRIVE TRAIN WAS PUSH TO THE RIGHT CAUSING THE ALIGNMENT OF THE DRIVER SIDE LEFT TIRE TO BE PUSHED OUT AS WELL. THE AIRBAGS DID NOT DEPLOY. THE CAR WAS 100% IMMOBILE AT THIS POINT AS THE REAR TIRE WOULDN'T MOVE. AFTER SPENDING AN HOUR I WAS ABLE TO REMOVE THE OLD TIRED AND PUT ON THE DOUGHT. I HAVE COMPLAINED ABOUT THE ISSUES THAT CASUED THIS MANY TIMES AND NOTHING HAS BEEN DONE. I AM SCARED OF THIS CAR AND WILL NEVER OWN A SUBARU AGAIN.
