NHTSA Complaint #11221622 — 2017 NISSAN TITAN

ERROR CODE P0527. FAN SPEED SENSOR. WHEN A/C IS ON AND THIS SENSOR FAILS, ENGINE GOES INTO HIGH RPM TOO INCORRECTLY COOL OFF MOTOR/TRANS. WHEN ACCELERATING, VEHICLE PERFORMS POORLY (BARELY MOVES). THIS HAPPENED WHILE WAITING AT A TRAFFIC SIGNAL TO AND FROM OUR DESTINATION AND OF COURSE WHILE DRIVING. DRIVER IS LEFT IN A PRECARIOUS SITUATION AS YOU ACCELERATE TRUCK BARELY MOVES ALL DUE TO A BAD SENSOR. SENSOR TELLS VEHICLE ITS OVERHEATING WHICH ISN'T THE CASE AS TEMPERATURE GAUGE / RANGE IS NORMAL. WOULD HAVE A BETTER DESIGN IF A) A SECOND LEVEL VERIFICATION OCCURRED COMPARING TRUCK TEMP BEFORE ENTERING SAFE (LIMP) MODE AND 2)ERROR CODE APPEARED ON DASH INFORMING THE DRIVER AND DEALER OF THE ISSUE. IF CODE HAD APPEARED ON DASH, DEALER COULD HAVE LOOKED UP CODE WHEN I CALLED AND SIMPLY STATED "TURN OF A/C TO RESUME TO NORMAL DRIVING". DEALER WAS BAFFLED UPON ARRIVAL WITH NO PRIOR REPORTS AND WITH NO INDICATION ON WHERE TO START TROUBLESHOOTING THIS ISSUE. TRUCK HAD TO BE TOWED. WOULD HAVE BEEN AN AWFUL SITUATION IN AREAS WHERE NO CELL COVERAGE EXISTS AND 125 MILES FROM HOME. LUCKILY WE HAD PLANNED TO RIDE IN SOMEONE ELSE'S VEHICLE THAT DAY OR THIS ACTUALLY WOULD HAVE OCCURRED. END USERS SHOULD HAVE A BOOKLET OF ERROR CODES AND POSSIBLE REMEDIES. TURNING OFF THE A/C WAS THE SOLUTION AND AN END USER QUICK FIX VS. LEAVING THE DRIVER IN A DANGEROUS SITUATION. TRUCK HAS ONLY 11,200 MILES AND IS A 2017 MODEL.
