I had a catastrophic Qashqai engine failure without warning. Thermostat housing split open leaking coolant, the engine overheated and an engine warning light only came on a few seconds before I came to a total standstill. RAC rescue van confirmed he had come across this problem with Qashqai’s before, my garage confirmed this was the issue and with minimal research we found other Qashqai drivers had exactly the same experience as me. My husband stopped just last week to talk to another Qashqai driver in Norwich who had the same issue. Nissan have been totally unhelpful - they said I would have to pay £180 for a diagnosis and of course as the engine wasn’t working I would have also had to pay for transport. The DVSA said Nissan were aware of this problem and were dealing with it but not so in my case - I have never had any notification that there was an issue with this part failing. Nissan gave an outline price for reconditioned engine replacement of £11,500 - £3000 more than the car was worth. The particularly frustrating part about this is I had loved my car - it was in pretty perfect shape. We have lost £8000-9000 and it seems incredibly wasteful when Nissan could have recalled Qashqais and changed this relatively cheap part.
