    Now at FIVE AC system failures in four weeks...

    Hi team - Just heard back from the GMC dealership with the diagnosis: they discovered that the connector hoses are leaking. It's a $3,000 job that will fortunately be covered by warranty. I should have some more information later from them today or tomorrow.

    White smoke issue

    It appears my name was mistakenly tagged somewhere in this thread and caused me to post a reply that belongs in another discussion.

    Back at the house now with yet another rental car. Unfortunately my "appointment" at the GMC/Cadillac dealership was nothing more than an opportunity to drop off the Denali after speaking with someone from the service desk for five minutes to explain the problem. Apparently it's going to take...

    Ok guys, today is the day...after a weekend of intermittent performance on the AC system, I'm now back in San Diego and have a service appointment at my local GMC dealership. I'll be bringing with me the service records of the previous four shop visits and hopefully we'll get some indication...

    2025 Yukon refresh

    What would you consider for the same or similar money? A newly redesigned Yukon Denali, or a well-equipped, low-mileage Escalade that is one or two years old?

    Completely agree with everything you said! I have this on my list to check when I get home to see if the sensors were replaced during any one of the previous four attempts. Reminds me of a problem I had last year with our swimming pool not heating up...a $30K rooftop solar system rendered...

    Now at FIVE AC system failures in four weeks...

    I posed this very question to the service guys after the very first go-round. He assured me that everything going into the truck was either GM or ACDelco. I verified what he was telling me was accurate on the service records after that first repair. And the second. And the third. And the...

    Thanks for all of this. I took the truck out again early tonight for a half hour and here’s what I found: 1. Yes, it does seem that the compressor engages. 2. Nope! The engine temp holds steady at 160, right down the middle. 3. Yes. It does seem that the fans run continuously. 4. I also...

    Do you think I should bring it to a GMC dealer at this point? I’m a little worried about the prospect of starting the diagnostic cycle (and OOP) costs all over again… Or just sell the thing? CarMax has a few of the same model year with more miles for the EXACT same price I bought mine five...

    UPDATE - I had to drive the Denali tonight and the AC appeared to be working a little better than earlier today. It could just be due to the fact that it was 90 degrees here in Palm Springs. But again, I drove 15 minutes each way to a restaurant with one hand in front of a vent both ways, and...

    It stops blowing cold. The air doesn’t get anything below “slightly cooler than the outside air.” I can put it on Max Cold and comfortably hold my hand in front of the vents for a hour without feeling the slightest discomfort. They get it working at the shop and it’s BLASTING cold air and then a...

    Hi guys I’m afraid I have bad news to report. We drove to Palm Springs from San Diego in the Denali. The AC system worked great during the trip here…and now that we’re here, it’s dead yet again. This marks the FIFTH time the system has crapped out on me in the last four weeks. I’m at a...

    UPDATE -- Just talked to the head of the shop to find out the latest. The replacement GM OEM condenser exploded! Refrigerant all over the inside of the engine compartment. So that's the good news. The bad news is that the quality of these OEM parts appears to be dreadful and we have burned...

    Now at FIVE AC system failures in four weeks...

    I will report back as soon as I have an update from them. My frustration level is starting to get the best of me as I feel like I’ve been living in Ubers and rental cars this past month. I’m also starting to worry that there is a gremlin in there that simply can’t be traced. Bad memories of my...
