Exclamation Leaky Radiators

We own a 2014 Grand Cherokee 73K mi and a 2015 Cherokee 125k mi. Both have radiator failures--leaks. I know of 3 others in my circle of friends with newer 2017/2018 vehicles. i have never heard of this with any other vehicle mfg.

I believe they are defective and should be replaced at no cost---vs $1000.00

What is your experience?

Good luck with that. Unfortunately, it's fairly common amongst all manufacturers. Aluminum core and fins with a plastic upper and lower tank bonded to the core.

So far, my JK has been fine and my GC is a 2017 with a lifetime maxcare warranty on it. No radiator issue yet. However, the old KJ Liberty had one go. I just did it myself with an aftermarket radiator.

When the JK finally goes, I'll investigate a solid aluminum radiator instead of a hybrid plastic/aluminum one.

read up on this sometime ago on the Jks. seems that in the jk they feel its the frame flexing the rad. This from some of the better known aftermarket makers having the same issues. So before you droop 1k on on all alloy one might want to read if it works any better with tank issue.

The jeep ones i read . Fiat claims it was for the Jks a production issue were the makers was over crimping the alloy to the plastic. This caused micro cracking in the plastic tanks that can be very hard to find. My nose can smell it but cant seem to find it as well. dont use much coolant in year. its not a dd. ill wait forthe leak to get bad enough to warrant replacement. Then? well if no one seem to have a handle on if its flex in the mounts might just get the factory one is rather cheep to but< should be too its fecal matter.

If it where mine i contact the dealer and ask if there is a TSB on the issue. If you have to replace a radiator and don't want to go for the solid welded ones get one from https://www.radiator.com/
They have a lifetime warranty and will replace it free if it fails.
