I had problems on many of my trips, some small some big... never complained. One of my trip the front rotor cracked, on one trip radiator top came off, etc, etc..
The problem here was that it was a family trip, before leaving Pajero was x-rayed, MRI, CT scan, even took her to a dentist and ENT.. all was fine... i think she is getting old. 
On the way back from Faisalabad, the pump nozzle leaked, liked the new sound shuck shuck shuck... will fix it tomorrow.
Oh btw trip was not ruined because of the faults in Pajero, it was because of the crowed up North, looked like people from Mars also came to visit Naran
