NHTSA Complaint #10938402 — 2015 RAM 2500

ON 6.7L CUMMINS DIESEL THERE CAN BE AN UNPREDICTABLY LONG ( UP TO 2 SECOND) DELAY BETWEEN WHEN THE ACCELERATOR IS PRESSED AND WHEN THE TRUCK ACTUALLY BEGINS TO ACCELERATE. THIS IS NOT TURBO LAG (WHICH MAY LIMIT THE AMOUNT OF POWER UNTIL THE TURBO SPOOLS UP). THIS IS NOT A STUMBLE. THIS IS AN ACTUAL DELAY IN THE COMPUTER APPLYING FUEL TO THE ENGINE. IT IS TOTAL DEAD TIME AS IF THE ACCELERATOR WAS NOT PRESSED AT ALL. IT HAPPENS UNDER THE WORST OF CONDITIONS, WHEN YOU NEED HARD ACCELERATION AND NEED IT NOW. IT HAPPENS WHEN YOU ATTEMPT TO ACCELERATE QUICKLY, ESPECIALLY WHEN YOU WERE COASTING OR HAD JUST LET OFF OF THE PEDAL. THESE ARE CONDITIONS THAT OFTEN OCCUR IN TRAFFIC WITH MANY OTHER VEHICLES NEARBY. THE LONG DELAY BETWEEN THROTTLE APPLICATION AND ENGINE RESPONSE IS EXTREMELY DANGEROUS. MY TRUCK HAS THE LATEST "FLASH" FROM THE DEALER, IT IS RUNNING THE MOST UP-TO-DATE FIRMWARE AVAILABLE FROM THE DEALER. DEALER STATED THAT THEY KNOW ABOUT THE ISSUE BUT HAVE NO PLANS TO FIX THE ISSUE.
