Actually this has nothing to do with Mazda North American Operations. MNAO won’t cover your leaky tensioner, period, since you’re out of new-car warranty at 40,000 miles in addition to your 2018 CX-5 is way over 3 years old.
No, your 2018 CX-5 has run out of new-car warranty long ago which is 3 years or 36,000 miles. The leaky timing chain cover is covered by 5-year / 60,000-mile powertrain warranty. Serpentine belt tensioner isn’t covered by powertrain warranty.
Here from an online Mazda parts seller:
Tensioner - Mazda (PE03-15-980C)
Replaces: PE01-15-980A, PE01-15-980B, PE03-15-980A, PE03-15-980B, PET2-15-980
MSRP $186.61 / Sale Price $134.34
Serpentine Belt - Mazda (PY01-15-909A)
Replaces: PY01-15-909
MSRP $46.37 / Sale Price $33.52
Water Pump Belt - Mazda (PY01-15-908)
MSRP $22.25 / Sale Price $17.89
All dealers would charge customers at MSRP, if not adding 10% ~ 30% more over MSRP, on all the genuine parts they used for service. The tensioner + serpentine belt + water pump belt should cost you at least $186.61 + $46.37 + $22.25 = $255.23 by a Mazda dealer. If your Mazda dealer quoted you $212 for all 3 parts that’s a pretty good price for the OEM parts. You can talk to the service manager saying you’d like to pay the parts on belts and tensioner but please waive the labor since the timing chain cover job would have to remove these 3, and they can just put the new parts you purchased from them back instead of using the old ones. Keep us posted.
Just see how many revisions on the prone-to-leak belt tensioner!
And BTW, the fix to the leaky timing chain cover can be tricky. Don’t be surprised if you still see some seepages after the repair.
I believe he said the Mazda dealer quoted him $212 for just the tensioner. Also, if any Mazda dealer can sell the same parts to the public for those online prices, then this dealer can too as they all pay the same price for parts. The service dept is being extremely greedy to try and make money on top of the MSRP price the parts dept charges them( which is most likey not msrp) and then charges the customer AGAIN. Every part of the dealership runs like 3 seperate businesses to one another....Sales, service and parts. No reason in the world other than greed that the service dept should be charging over list price on parts and trying to get him for labor as well for something required to be removed and replaced as part of the timing cover job!
