NHTSA Complaint #10519810 — 2013 FORD F-150

6/08/13 WHILE TRAVELING FROM KINGSVILLE TO RIO HONDO AT 6 AM FOR A FISHING TRIP, I ACCELERATED HARD TO PASS A SEMI-TRUCK. MY F150 SHUDDERED VIOLENTLY IN THE BACK END, AND I FELT A SIGNIFICANT LOSS OF POWER. THE CHECK ENGINE LIGHT BLINKED EXCESSIVELY BEFORE EXTINGUISHING. THE TRUCK RESUMED NORMAL OPERATION FAIRLY QUICKLY, WITHIN 5 SEC. I CONTINUED TO MY DESTINATION WITH NO FURTHER PROBLEMS, MAKING SURE TO LIMIT MY SPEED AND MAKE NO MORE HARD ACCELERATIONS. THE WEATHER WAS RAINY AND WET CONDITIONS. I INTENDED ON INVESTIGATING THIS ISSUE ONCE I RETURNED HOME. 6/09/13 THE TRUCK HAD BEEN PARKED AND NOT DRIVEN UNTIL MY DEPARTURE ON SUN, 2 PM. ON MY WAY HOME I WAS FORCED TO ACCELERATE QUICKLY ON HWY 77 ON RAMP FROM FM 107 TO KEEP UP WITH TRAFFIC. THE TRUCK ONCE AGAIN SHUDDERED VIOLENTLY AND THE A/C BEGAN BLOWING HOT AIR, THE LOSS OF POWER WAS MUCH MORE SIGNIFICANT THAN THE LAST EPISODE AND I WAS FORCED TO PULL ONTO SIDE OF HWY 77 TO AVOID BEING STRUCK BY TRAFFIC BEHIND ME. THE ENGINE LIGHT BLINKED AND CONTINUED TO STAY ON. THE TRUCK RESUMED NORMAL OPERATION; HOWEVER THE LENGTH OF TIME BEFORE THAT HAPPENED WAS MUCH LONGER THAN BEFORE. I WAS CERTAIN I WAS GOING TO BE STRANDED AND IT WAS NECESSARY FOR ME TO TAKE EMERGENCY MEASURES. THE WEATHER WAS HOT AND DRY. *TR
