Got my CarPlay update done on the 6.

Got my CarPlay update done and the dealer promptly told me my 2016 Mazda6 with 51,000 miles needs...$1,200 of work.
They want to flush the coolant, flush the brake fluid, do the “GDI emissions service”, replace the belt tensioner, and replace the V-belt and the stretch belt. Needless to say, I told them no.My mechanic and I will check the belts, but the car runs as quiet as a mouse so I can’t imagine there’s anything there that is bad. My last car was a 2008 Mazda3 and it squeaked and chirped like hell when the tensioner was going out.
What’s sad to me is they usually don’t try to scam me with shit like this...because they know better and they know I’m OCD AF about my car and it never needs anything that I haven’t already done. But, today, I got a new advisor that wasn’t familiar with me from back when the car was under warranty and I actually visited the dealer for service.

I fell for the coolant flush scam one day. I was weak, and I am ashamed.
-
Im at 90k on my '16 miata and the belt recently started squeaking for a second on cold start ups.
But what the shit is the GDI emission service? -
@mazda616 shouldn’t that be FL22 coolant in your 6? A brief search for my own reference says 10 year / 120k on the OEM fill. Same search says that the rad cap should say FL22 on it somewhere. Subaru has been using long life coolant since 2008, and I would imagine most manufacturers are doing so, too.
I could see belts if they are dry and/or cracked, but the tensioner seems dubious if it doesn’t seem to be causing issue.
Subaru has me conditioned on brake fluid replacements every 2.5 years or 30k. Some view that as excessive, but I’m willing to go a bit overboard with that one.
GDI service might be referring to carbon buildup on the valves? More info would be needed there.
-
GDI service might not be bullshit.
GDI engines suffer from carbon build up on the valves. If left to it's own devices, it'll get bad enough where you'll start misfiring and pinging and reducing power/economy. If it's just a can of CRC down the throat, do it at home by yourself. If it's the walnut cleaning, that's about $4-600 to be done as it's a pain in the ass.

@boxer_4 BMW says two years on brake fluid. Sure it could go longer, but it's one of those items that you might as well change since it is hydrophilic and cheap to change.
-
@e90m3 I find that fresh brake fluid is highly underrated by most people. I’d rather change it often.
-
My mechanic is going to check the belt tensioner and both belts tomorrow. If they need replacing, we’ll order them and take care of that.
I checked the Mazda maintenance schedule in the owner’s manual. Coolant change isn’t advised until 10 years or 120,000 miles. Says nothing about brake fluid. I might ask my local tire/brake shop what they think.
