This is a great idea ? Did you do it ? If not I am happy to and post the results here - it could take a month though. I found out after I purchased my car that the housing had been replaced.Nolite81 wrote: ↑Wed Jan 22, 2025 12:45 pm I was wondering if anyone had submitted a FOI request to Nissan (specifically Nissan UK as that seems to be where the majority of the problems are) regarding the 2019 Qashqai thermostat housing, i.e. the number of vehicles with the problem, the number of official replacement thermostat housings sold since 2019, if and when the manufacturer/supplier of the part had changed and why? And if so what was their response?

Did you find out if it was replaced after it had failed, or done as a precaution?

It was after the problem - the job sheet mentioned 'customer reports break down, smoke from engine (I suspect it was steam), smell of burning and car unable to be driven' diagnosis: thermostat and housing replaced. Note *Customer wants to retain part* I can only imagine they are a customer of this group.
Nissan never supplied this information to me - it was only following a SAR and a very long complaints case with Nissan UK that I managed to source the information. The car in my ownership has had a very long list of issues, but none seemingly related to a failed housing - mostly electrical components. Worst car we have ever owned.

SAME PROBLEM HERE 2019 1.3 engine. NO warning at all while driving highway suddenly lost power. Bought the car NEW, fully serviced at Nissan only 50.000 km and still under 5 yr warranty. Waiting for the official dealer in Cyprus to tell me the results. I hope i stopped on time to avoid needing a new engine. Why they did not recall the thermostat ?????? so many customers are suffering . i will keep you updated !!!

Hello again,
I found the problem with the Mercedes thermostat.
Due to the fact that the both electrical connectors are identically at Merc thermostat,
the mechanic reversed the wires by mistake, so the temperature sensor received 12 V and it broke down.
I verified the temperature sensor of Mercedes thermostat and it is broken.
I will try again as soon as possible.

As much as I hate to say, there were over 51,000 quashqai's sold in the UK alone in 2019 (unsure exactly number that were 1.3). Add all the ones sold to the rest of the world, and it's sadly not a major problem for Nissan. As soon as they recognise the issue with some cars, they they take on a whole world of financial loss and responsibility. Even the Ford ecoboost issue which is far bigger has only been recognised officially in the USA. In the UK they still deny it.charisk123 wrote: ↑Mon Jan 27, 2025 8:01 am SAME PROBLEM HERE 2019 1.3 engine. NO warning at all while driving highway suddenly lost power.

Did you have the issue just before Christmas? A 2019 car would be out of its 5 year warranty by 31/12/24 at the latest surely?

Hello, Ersin!! I don’t know how you managed to understand it, but you did an amazing job this time too.Ersin wrote: ↑Mon Jan 27, 2025 1:46 pm Hello again,

It happened to me last week. They confirmed that i am covered by the warranty. I bought the car February 2020. They need to replace the engine. They did not confirm that tha termostat exploded/splitted but just for an unknown reason the car suddenly run out of water/antifreeze.Foggypants wrote: ↑Mon Jan 27, 2025 10:16 pmAs much as I hate to say, there were over 51,000 quashqai's sold in the UK alone in 2019 (unsure exactly number that were 1.3).

You can add me to the list of people where the thermostat housing has leaked.
I have a 2019 reg qashqai, had from new and done about 42k miles. Car stopped blowing hot air, the fans were only blowing cold air. No warning sign, and engine temp was fine and stable. Was only driving on local roads, so never got above 40mph. Did some search online, likely cause is low coolant level, checked and saw there was no coolant left. Went and brought some coolant and next morning tried to fill it up, but it just kept emptying, looked under car, and could see it leaking loads.
Took to my local independent garage, they said it looks like the thermostat housing is leaking and will need replacing. They couldn't do anymore as closing time for rest of weekend. I left my car with them.
I'm really hoping the engine hasn't been damage.
Has majority of people who have had a leaking termostat housing unit also had damage to the engine and needed to replace that as well? Or is it more 50/50 on whether the engine will have been damaged as well?
