NHTSA Complaint #11384722 — 2015 RAM 1500

AEM UPDATE CAUSED VEHICLE TO PERFORM IN AN UNSAFE MANNER. HESITATES UPON ACCELERATION FROM STOP. TRANSMISSION SHIFTS IRREGULAR AND NO LONGER SLOWS VEHICLE DOWNHILL. DURING ACCELERATION MOTOR CAN REDLINE AND CAUSE A RAPID DECELERATION. NEVER SURE EXACTLY WHAT IS GOING TO HAPPEN WHEN PRESSING THE FUEL PEDAL. NEVER SURE IF IT WILL SAFELY GO WHEN IT IS SUPPOSED TO. FUEL ECONOMY IS ALSO REDUCED FROM 28 MPG TO 25 MPG. IT IS NOW A SCARY VEHICLE TO DRIVE. WAS IN RIGHT LANE EASTBOUND ON HIGHWAY 152 GOING OVER PACHEO PASS BEHIND SLOW TRUCK TRAFFIC AT APPROXIMATELY 30 MPH. WHEN ATTEMPTING TO ACCELERATE WHILE CHANGING LANES THE MOTOR WENT TO REDLINE AND DEPOWERED. I QUICKLY HAD TO BRAKE AND GET BACK IN THE RIGHT LANE BEHIND THE TRUCK TRAFFIC. THE VEHICLE HAD NEVER DONE ANYTHING LIKE THAT IN THE 4-1/2 YEARS PRIOR TO THE AEM. THEY RUINED MY TRUCK WITH THE MODIFICATIONS, IT IS A MAJOR SAFETY ISSUE WHEN THE TRUCK SHUTS OFF POWER WHEN ACCELERATING.
