High Temperature Coolant Reservoir Failure

Don't panic my friend!
We "self select" in terms of reporting "failures" on this enthusiasts' forum... while extremely helpful in understanding what "might" go wrong, there's also a need to put such reports into context in terms of a statistical probability. I'd venture to say that by my "back of the envelope" estimate the vehicle is far more reliable than many other marques.... (a million V8 engines in the recent GM recall, Honda and Hyundai likewise with the curse of manufacturing debris left in engine blocks)...
(Yes, my HP coolant reservoir also developed a crack...it's a BMW issue across many models).... but I'm relaxed about the Grenadier's overall reliability

We are in agreement but it is aggravating at the very least. I should have kept my Land Cruiser 200 as the reliable, never have to think about it rig.

I appear to have joined this club yesterday. I noted the smell of coolant after arriving home from an hour-long highway ride. Didn’t see any obvious wetness, but smell was strongest by the passenger-side reservoir (LHD).

Read the posts here and went back out and could see the white residue around the seam and then noticed dried streaks in the dust below the seam and on the chassis below.

Bought some coolant from the dealer today but found that the reservoir was full (in fact the entire yellow indicator was under fluid). This was a cold engine, btw.

Have an appointment for the dealer to examine next week - will be interested to see what they say.
