But, I will add this: I bought my 2012 StreetGlide used with 5000 miles on the OD, and it was 6 months old. I’ve never had an issue with the braking system. However, about 3 years ago I got a letter from the MoCo. Basically it stated that issues have been discovered with DOT brake fluids, that accumulated moisture into the system and had caused braking problems.

The letter went on to state that I should immediately take my bike to an authorized service dealer, and have the brake system flushed, and refilled with new fluid. And, then have the system flushed and refilled with fresh brake fluid every (2) two years thereafter. I’ll have to dig up that letter to see if it recommended a specific brake fluid, I don’t recall.

So then I buy a new 2017 Chevy Colorado Z71 4WD Crew Cab pickup. After about 15,000 miles I noticed a vibration that I thought might be a front wheel out of balance. The problem gradually got worst.

Log story short: I find on the coloradofans.com forum that others have the problem as well, and that GM has a Technical Service Bulletin (TSB) out addressing the issue. The problem is with the new 6-speed transmission. That’s where the vibration and other anomalies are coming from. GM found the problems come from the transmission fluid accumulating moisture and causing the issues. GM was working with the oil company (transmission fluid) to come up with a solution. GM’s new TSB recommends a flush and fill with a new type of tranny fluid. I had this done to my truck at the 30,000 mile service interval and the vibration problem went away.

Oils accumulating ambient air moisture? That’s what ethanol does to gasoline right?

.

So this letter was something other than the brake fluid recall that was issued less than 2 years ago? That recall only covered '08-'11 models.

2018 10 months old I’m with the call BS crowd!

I think saying the bike might be older than 2 years, could have been built/sold2017. But its odd on such a small item, they would cover. If he is looking for warranty coverage, then most have been sold within 2 years. Ya the fluid may be older than that due to being built earlier, I would think they would still go with under warranty.

If the manual says to flush it every 2 years, are you really expecting the first flush to be 2 years from built, or sold? I would say sold, unless it was his widow's lawyer, then built. But I dunno.

This came up once or twice on the forum earlier. I mentioned the '12's and '13's, probably other newer bikes have the same part number for the Hyd. Cont. Unit, but some one mentioned they think the vendor of the HCU was changed due to reliability on the affected HCU's. so HD just tweaked the DOT 4 fluid to "Premium", less likely to be affected by moisture/corrosion to the brake components.
