Is it really any more or less sloppy than the CX-5's own engine stalling problem? It's worth noting that, unlike the CX-5, the RDX's stalling problem isn't even widespread enough to require a recall.If you think so.... The MOTOR has been out longer than the RDX itself so it has been a while and the issue affects Accord owners as well. IMHO it is indicative of sloppy work on Honda's part. As I said my 16 RDX was full of issues which is why I sold it rather than holding onto it. I originally planned to keep it a long time but with my issues, decided it was best to sell before it got up in mileage (I sold it in '19 around 60k). As I said, I hope yours is trouble free....
(Note: I'm not sure how long the base motor has been around, but the RDX/Accord stalling issue was related to the intercooler, which only affects the 2.0 turbo models and I'm 90% sure those were not offered until around 2018.)
I don't doubt that your 2016 RDX had a lot of problems though. As noted by others in this thread, Honda really got lazy during that generation of cars. I take some comfort in the fact that their CEO publicly acknowledged their "quality crisis" a couple years back and vowed to fix it.
