Lifetime MaxCare has really gone down the drain. The screen on my 8.4" UAQ radio started to delaminate a few weeks ago (a widely documented issue with 2018 Grand Cherokees). Took my vehicle into the dealer yesterday, and, as I expected, they immediately said that the radio would have to be replaced. Luckily, it's covered by my lifetime MaxCare warranty and they have the radio in stock. However, my service advisor said there is apparently a new procedure that dealers must follow to get approval for claims under the lifetime plans. According to my service advisor, as of April 1, 2023, lifetime plan claims greater than $1,000 must be submitted via email. There is no longer a phone number for dealers to call to get claim approvals. My advisor said that whoever monitors this email account is typically VERY unresponsive, and he often has to wait at least 3 days to get a response. And when they do respond, they usually make the technicians jump through hoops and perform all kinds of secondary diagnostics before they will approve claims.
So, my advisor submitted my claim via email yesterday (more than 24 hours ago at this point) and he still has not received a response. He reluctantly let me have my vehicle back while we wait for approval, but he said that if the MaxCare people find out, they might deny my claim because "driving the vehicle with a known issue could cause further damage."

Well, I don't think a peeling radio screen is going to affect the rest of the vehicle, so I'll take my chances.
I was extremely happy with my lifetime MaxCare plan up until this point. Like someone else said earlier in this thread, it definitely seems like they are trying to aggravate customers into not wanting to use this warranty.
