Checked my coolant resevoir tank and no coolant topped off and smelt colant smell after driving notice pink coolant drops coming from front of vehicle and noticed radiator on driver side is covered in pink pink coolant crust. Anybody else have issues with radiators leaking ?

In that last pic looks like you have some damaged fins along with a damaged clamp that holds the header on. Might have jammed to much mud up there while playing offroad.

They look like weak units but most rads are built this way this days . I remember I had to change a radiator once on a honda and I think it had about 20k or so in miles. It leaked even though i still looked relatively new. I don't have too much faith in the one I have in my 2020 either.

Same thing at 58k. @Alexxkaztcjl did u fix this? I went to the dealer and I no longer under warranty (2018 jlu as well 58k miles) and they estimated the fix might cost around $900.
Couple of months ago I noticed the coolant tank was empty even when the engine was running after 40mins so I top off. This was during the cold days. And now the weather is getting higher my theory is that coolant expanded and might have caused pressure on the radiator and leaked??? That's my theory but I'm not an expert on this. .

You’re right, you are not an expert on this...the radiator leak came first. The coolant systemwill relieve pressure automatically through the cap if needed, and unless you are overheating, even that won’t happen during normal operation.

the only fix is a new radiator.
