Just looking to see if anyone else is having the same issue as my 2022 RDX A-spec Adv. I have only 9,000 miles on it and a few weeks ago every warning started to cycle thru on the main instrument panel: road departure mitigation problem, blind spot info system problem, auto high beam problem, idle-stop problem, cruise control problem, lane keeping problem, and collision braking problem. Plus, every feature on the center console stopped working, except the radio, the directional worked but there was no sound or panel lights indicating they were on, it was nuts, but it still drove fine. Check engine light never popped up. Then when I got it home I couldn't turn the car off unless I held the start/stop button for a few seconds, but the media display continued stay on even if I opened the door. I also lost the ability to lock the car. I towed it to the dealer and they replaced the body control module and everything seemed to be working for 2 days, then the same issues started back up again. So, currently it's back at the dealer for a second time and they just informed me the whole wiring harness needs to be replaced. I don't have high hopes and feel they are just going to be chasing the issue until they find the fix.

So, has anyone had these issues?

Sounds like Acura is just throwing parts at the RDX to see what works. I'm on my 4th and 5th Acura. Acura vehicles really really hate low power. Every time I had that many codes/alarms/warnings is because of low power issues. Usually, a bad Acura battery starting to fail (bad cell). Second issue is the OEM alternator not putting out enough power to recharge the battery and run the vehicle (usually at +100,000 miles type of issue). Next is a grounding issue causing the system to send error codes (poor ground on chassis or battery with being loose or has corrosion). Sometimes an engine bay fuse box or control module seal isn't tight and moisture is causing the issue. Then; a power drain issue from a bad module or electrical part somewhere causing the error codes or draining power too low causing error codes being reported from a lot of systems downstream.

I've noticed the Acura codes seem to give you the symptoms from the issue instead of the exact part causing the problem. Acura wanted to change out my alternator because of the codes when the real issue was a dying cell in the OEM battery.

We had a problem similar on a different car- a 2 year old Kia Niro PHEV with 2800 miles, it locked up and we could not get in, then when we finally did get in, it wouldn't start, we couldn't open the hatch or anything. We jumped it and took it in. It was the OEM battery. KIA batteries were out of stock/ on back order at the time so the matched it with a nice aftermarket for us and installed it- under warranty.

Enthusiasts looking for a sophisticated luxury SUV often flock to the 2022 Acura RDX. It's labeled as being “bold with purpose” by the automaker. Instead of offering the boldness promised, this SUV seems to provide a faulty electrical system, malfunctioning service brakes and a poorly-built structure

Thanks so much for your responses, I really appreciate it. My car is still in the shop, it’s been 2 weeks, I guess the dash harness was back ordered. I’ll just beat on their loaner for a few more days then. Lol. I’m not feeling too optimistic about the repair though. So fingers crossed. I’ll update after I get it back and drive it around a little bit.

Yeah, I wouldn’t call it a luxury car that competes with Audi, bmw or Mercedes, but I think it’s definitely better than the Honda crv. There are a few things that drive me nuts about the RDX though, like the 4 cylinder turbo (it’s no faster than my son 2013 accord or get better MPGs than my wife’s Q7), the touch pad, the speed limit shown on the HUD is a joke (not sure why they don’t just use the speed limit baked into the navigation software). But it’s still a nice car. Maybe they’ll produce a type s rdx in the future. I’m just wanting a bit more performance out of a small SUV.
