Hey everyone, I’m looking for some help here and wondering if other people have run into these issues as well.
My ‘24 4BW has two obnoxious issues the dealer is struggling to diagnose but also doing a terrible job even trying to duplicate the concern. First off, the AC will blow ice cold for a few minutes then fluctuate in temperature as if I’ve turned off the AC button and left the HVAC in LO, then the cold ac will start again. Vehicle speed, blower speed, ambient temperature, set to auto, nothing effects this and it is fully intermittent. Dealer evacuated and recharged AC (no leaks), reprogrammed the BCM and are now saying they can’t duplicate it.
Second is intermittent clunk from the rear. I’ve seen a couple other guys with a rear clunk fixed with replacement rear shocks, which my dealer did, but the clunk is still there. Happens 10-30mph, louder in sport or track suspension modes. I’ve checked torque on every nut and bolt in the rear suspension and nothing was loose, no visual damage or wear.
These issues are driving me crazy and making me consider trying to get the car bought back, which I don’t want to do because I love this car. But I’m really hoping for someone with similar concerns on their 4BW and any advice is welcome. Thanks in advance.
