I got my 2019 RDX back in August of 2018. However, recently, I noticed that the engine is idle very roughly on cold start (parked over night in a garage). I can feel the driver seat vibrating. I can see the RPM needle raising and dropping. I don't recall this happening last winter. Does anyone else have this problem as well? Thanks!

 

There’s a TSB on this. Bring it to the dealer there’s a fix.

I don’t know if this is the same thing but I feel mines isles rough every time I start it, it calms down after it’s warmed up, I usually don’t notice it because I remote start it every morning, but if it’s cold and I don’t remote start, it feels like I have my foot on the gas in the mornings,

 

I have only had the car a week (2020) and was thinking to myself my god this car idles rough when I start it and go into reverse.

 

At the dealership now for break squeaking issue, told the service guy about the rough idle. He tried to tell me they would have to keep it overnight to check, i said ok give me a loaner, then he changed it and said they could look at it, I showed him the service bulletin.

i wish dealerships weren’t like that, i mean we freaking pay for these cars and when a legitimate issue arrives that is covered under warranty just look at it and fix it. Does the fixing cost the actual dealership anything? I would hope not, and if it doesn’t why make it difficult??
