Hey is there a chance the thermostat was charged and it was aftermarket? They need the nissan thermostat mine did the sameHelp. I have a 2005 Xtrail, that cuts out when the engine gets hot. This has resulted in me breaking down on the M'way, when I have gradually lost power, breaks, steering wheel the lot.
The mechanic thought it was the insulation?? around something underneath, meaning one of the sensors underneath is picking up it is overheating, telling the engine to cut out.
Sorry to be vague, cars not really my thing. Many Thanks for the reply.
