2008 Nissan Pathfinder power train problems

“Crack in defective radiator allowed coolant to mix in with transmission fluid. Coolant caused transmission to fail while driving it. transmission changed gears on its own and would not shift properly and engine just shut down”

“Bought vehicle I’m second owner it was sold as is from a dealership with airbag lights on after a certain amount miles check engine light came on said I had e -regular voltage to fuel injectors 1 gear started slipping then loss of power when accelerating next revolutionary trans-sensor went and now when I start the vehicle the A/T ECU Fuse keeps blowing out and the radiator coolant has transmission fluid mixing into it.”

“The contact owns a 2008 Nissan Pathfinder. The contact stated while driving 45 mph, the vehicle downshifted independently. The contact stated that the check engine warning light was illuminated. The contact was able to continue driving to his destination. The contact took the vehicle to an independent mechanic and was informed that the transmission fluid needed to be changed. The contact took the vehicle to a second independent mechanic and was informed that the radiator and the transmission needed to be replaced. The vehicle was not diagnosed nor repaired. A dealer was not contacted. The manufacturer had not been informed of the failure. The failure mileage was approximately 116,000.”

“TL* THE CONTACT OWNS A 2008 NISSAN PATHFINDER. THE CONTACT STATED THAT UPON PLACING HER VEHICLE INTO REVERSE, THE VEHICLE SHUT-OFF WITHOUT WARNING. THE VEHICLE STARTED ROLLING BACKWARDS. THE CONTACT AND HER SON EXITED THE VEHICLE, TO MANUALLY STOP THE VEHICLE FROM ROLLING BACK AND HITTING A BUILDING. THE CONTACT THEN HAD THE VEHICLE TOWED TO AN INDEPENDENT MECHANIC, WHERE THE MECHANIC REPLACED THE ENGINE COIL BLOCK HOWEVER, THE VEHICLE STARTED TO OVERHEAT AT START-UP. THE CONTACT STATED WHILE DRIVING AT UNDISCLOSED SPEEDS, THERE WAS WHITE SMOKE COMING FROM THE ENGINE WHILE THE TEMPERATURE GAUGE SHOWED A HIGH ENGINE TEMPERATURE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND INFORMED HER THAT THE WARRANTY HAD EXPIRED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 93,500.”

“AIRBAG LIGHT HAD COME ON INDICATING AN ISSUE, BUT ALSO LIGHT AND CONTROLS ON THE STEERING WHEEL ARE FAILING. VEHICLE HAS NEVER BEEN IN AN ACCIDENT AND THERE IS NO REASON FOR THIS FAILURE. ABS BRAKES ACTIVATE RANDOMLY WITHOUT WARNING PREVENTING AND CAUSING THE INABILITY TO STOP. ABS CAN NOT BE STOPPED UNLESS I STOP AND TURN OFF MY VEHICLE AND START AGAIN. VERY DANGEROUS. CANT STOP WHEN I NEED TO. DURING CITY DRIVING ON A DRY SURFACE AND APPROACHING A STOP LIGHT MY BRAKES FAILED SEVERAL TIMES WITH THE ABS ACTIVATING AND MAKING IT IMPOSSIBLE TO STOP. RANDOM AND WITHOUT WARNING. FRONT DIFFERENTIAL CRACKED FOR NO APPARENT REASON AND DIDN'T PROVIDE ANY WARNINGS, PINION SEAL LEAK APPEARED LESS THAN TWO YEARS. IN ADDITION VEHICLE WAS IN SERVICE FOR EVAP SYSTEM 11 TIMES IN THE FIRST YEAR WITHOUT RESOLVE. GAD CONSUMPTIONS WAS HORRIBLE AND BELOW ANY SUGGESTED MPG. TIRE SENSORS HAVE NEVER WORKED AND FAILED TO ALERT LOW PRESSURE IN TIRES. TIRE PRESSURE HAS BEEN UNSTABLE NO MATER WHAT TIRES ARE INSTALLED OR HOW MANY SENSORS ARE PUT ON. STABILITY IN STEERING IS SLOPPY WHEN GOING OVER ANY KIND OF BUMP IN THE ROAD. UNSTABLE WHEN DRIVING. SPEED CAN CAUSE PROBLEMS WHEN DRIVING…”

“WHILE DRIVING, FROM A STOP, A LOUD CLUNK OCCURRED AND THE VEHICLE WOULD NOT SHIFT OUT OF LOW GEAR. UPON ARRIVAL AT HOME AND INSPECTION, IT WAS NOTED THAT THE COOLANT WAS CONTAMINATED WITH A DARK FLUID. THE VEHICLE WILL NOT ENGAGE ANY GEAR AT THIS TIME AND IS NOT DRIVABLE. RESEARCH INDICATES THAT SUSPECTED CAUSE IS CROSS CONTAMINATION BETWEEN COOLANT AND TRANSMISSION FLUID, MOST LIKELY DUE TO RADIATOR DEFICIENCY.”
