What owners say about the power train
Verbatim from NHTSA complaints, newest first
“The contact owns a 2008 Nissan Frontier. The contact stated that while driving at speeds over 40 MPH, the vehicle would shake and vibrate. The vehicle was taken to the local mechanic who diagnosed that the radiator fluid had leaked into the transmission causing severe damage to the transmission. The contact was informed that the transmission and radiator needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure but no assistance was offered. The failure mileage was 86,000.”
“The transmission cooler integrated into the radiator failed damaging the transmission by cross contamination of fluids. Loss of power on a narrow country mountain road was not safe. I learned that this problem is very common. I feel that Nissan should have replaced the radiator before thousands in transmission damage occurred.”
“Transmission fluid cooler integrated in the radiator that allowed engine coolant to mix with and contaminate the automatic transmission fluid causing damage to the transmission. Radiator had to be replaced along with flushing out of the trans fluid at a service station costing a few thousand of dollars. Months later the check engine light went on and found out that the transmission is slipping caused by the fluid contamination.”
“TRANSMISSION FAILURE DUE TO COOLANT IN TRANS OIL CONTAMINATING TRANS COMPONENTS. TOTAL TRANS REBUILD/REPLACE RADIATOR AND TRANS COOLER. 130K MILES ON VEHICLE - LOW MILES FOR A 2008 FRONTIER. THE VEHICLE SHUDDERED, HESITATED, WOULD NOT PICK UP SPEED AS IT SHOULD, WAS HAVING DIFFICULTY SHIFTING THRU GEARS AS IT TRANSITIONED FROM STOP TO MOVING, TYPICALLY AROUND 30-40 MPH UNDER LOAD (ACCELERATING). WE HAVE SINCE FOUND OUT THIS IS A KNOWN PROBLEM. EXPENSIVE REPAIR!”
“DRIVING ON STREET TRUCK BEGAN TO SHAKE AND VIBRATE I LOSS POWER AND CAR COULDN'T SHIFT INTO GEAR IT SEEMED I PULLED OVER AND STOPPED AND SHUT OFF. CAR I STARTED IT BEGAN TO DRIVE AND IT WUDNT GO OVER 30MPH I STOPPED AND NOTICED LEAKING UNDER THE TRUCK TOWARDS THE ENGINE AND WHEN I PRESSED ON GAS IT WOULDN'T GO STILL SO I STOPPED AND GOT TOWED”
“FIRST LONG TRIP SINCE I BOUGHT THE USED TRUCK, A TRIP TO OAKRIDGE, 90 MILE ROUND TRIP FROM HOME. THE TRUCK MADE IT BACK TO OUR DRIVEWAY, THEN WHEN I PUT ON THE BREAK FOR MY HUSBAND TO GET OUT, IT WOULD NOT MOVE AND ALL THE DASH LIGHTS CAME ON. I COULDN'T BUDGE THE TRUCK. IT WAS LOCKED UP. COULDN'T MOVE THE STICK. THE ENGINE QUIT. FORCED IT INTO PARK AND TRIED TO RESTART, BUT NOT A SOUND. THE NEIGHBOR CAME OVER WITH HIS CODE READER. IT SAID P1000. BATTERY CHECKED GOOD, GOT A NEW ONE ANYWAY BECAUSE ITS AGE. GROUNDS WERE GOOD, BUT CLEANED ANYWAY. HAD IT TOWED TO DEALER. THEY PUT A NEW TRANSMISSION IN.”
