I think I was two weeks into the ordeal when the dealer provided 2021 cx5 touring loaner. No cost to me.What was your temporary vehicle situations? Did Mazda actually provide a loaner for 11 weeks since it's warranty work? You shouldn't be responsible for incurring rental costs.
Result of the dealer visit. Basically they couldn't find a leak, even after asking them to take a second look just in case. I will be monitoring the coolant level until my next oil change, and then I'll be sending a second UOA out to see if K levels are still elevated, and take it from there.
If Mazda didn't revise a known weak point a good couple of years ago, they are in trouble. 2.5T has been used across the lineup now for a while. Could be CX-5's and Mazda 6's next. Would really hamper their future if it becomes more widespread.I should have my cx9 back with new engine anyday now....i am definitely hoping to get some answers on coolant leak root cause and if new engine block/head are newer revision.... and if revision corrects defect.
Pushed to next week around Wed........ needed to order turbo gaskets...I should have my cx9 back with new engine anyday now....i am definitely hoping to get some answers on coolant leak root cause and if new engine block/head are newer revision.... and if revision corrects defect.
I agree with you that engine defect issue should already be resolved, but i have not seen anything to verify that.If Mazda didn't revise a known weak point a good couple of years ago, they are in trouble. 2.5T has been used across the lineup now for a while.

I still suspect this is a limited problem as most people who have a problem head online to discuss. Never hear from the 99% that don't have a major problem and talk about their vehicles on forums.
The million dollar question is the starting build date of a revised 2.5T, if indeed it happened.I agree with you that engine defect issue should already be resolved, but i have not seen anything to verify that.
Ya, who knows. That change could be due to ecu program changes or they were just conservative with their ratings in the earlier models and decided they could achieve the higher rating reliably enough to up the rating (and car manufacturers do that for some reason, for example the new Supra seems to produce significantly more power than what Toyota claims).The million dollar question is the starting build date of a revised 2.5T, if indeed it happened.
You have to wonder if it was when the torque changed from 310 to 320 lb ft (I believe it was the 2020 model year).
Fair observation. I’ll offer this anecdotal evidence on a similar issue with Ford 1.6L engines. Most of them were having coolant loss before 50k miles. Mine made it to 110k before it started to lose coolant. There’s a lot of the final model years of that engine finally making it to 100k+ that are failing, what seems like, more often now.Is it just me or do these failures happen around 50K - 60K miles? Has anyone seen some encounter this issue with a more high mileage vehicle? Perhaps it's the sort of problem where if it will present itself it will do so within a certain time otherwise you have a "good one" and it'll just last as long as any other engine. In other words, those that will fail will fail early.
Having said that, mine is at the 65,000 mile mark (105,000km), so I might be right at that moment of truth myself! (last I checked my coolant level is right where it should be, knock on wood)
