UPDATE:
So the mechanic said apparently the charge pipe is secured on with a screw clamp torqued to 29 N-m at the factory, but should be 28 N-m. That 1 N-m makes all the difference in how the connection seats, which leads to the charge pipe being able to separate from its connection while under boost. This can happen over time.
Mine is all fixed and runs like it did before the Limp mode. Should things change…I'll report back.

I was driving on the highway about 75mph and I was trying to pass someone. Then my engine cutout and the engine light came on. I was unable to accelerate I believe it’s called “limp” mode. I had to pull over, shut the car off and turn it back on and everything is fine.
Has as anyone had this issue? I use premium gas, and the car has 1500 miles on it.

In all my decades of driving, I've never encountered a situation where coasting resulted in nearly getting rear ended. I can't help but think that many of these claims of near misses are sensationalized.
#286
I saw a guy on the Merritt Parkway in CT (2 narrow lanes, cars only with average speed of about 80). His car apparently died and he was coasting in the fast lane attempting to move over....it was a nightmare. People were swerving like crazy trying to avoid him. The Merritt has virtually nowhere to pull over and the traffic is very heavy and fast. I drive the Merritt daily and this is one of my concerns with the RDX. Next test drive I am going to do a ton of rapid accelerations simulating passing to see if I can induce this (but not on the Merritt). Coasting is probably not as horrible IF you have time and a path to move off of the highway.

My car went into limp mode again. This is the 6th time, if I’m not mistaken. Car had a burning smell when I got out and it shook worse than it ever has before. Codes on my obd reader were cylinder 1 and 4 misfire. Car was towed into my dealer and I’m in a loaner

Any common conditions when it's happened, such as rainy? Keep us posted.

I don't believe they are sensationalized. I know mine wasn't. I guess you drive in a good area. I'm in Northern Virginia where tailgaters are normal. Imagine entering the highway and just as you speed up to merge the car goes into limp mode. Construction area/no shoulder. There are many such scenarios that could lead to an accident. Also, someone may get scared when their car goes into limp mode and slam on their brakes because they have no idea what's going on.

Then that's the tailgater's error.

After 6 times of the issue occurring Acura has authorized a repair to my car! IT TOOK 6 TIMES. They are replacing my fuel injectors. Personally I think this won’t fix the issue... but time will tell I suppose. The dealer will be cleaning my engine out as well they told me.

Been there, more than once, but it wasn't an RDX, it wasn't by choice, and it wasn't fun. Suddenly losing power while merging into traffic is no friggin joke.

#298
We'll keep our fingers crossed that new injectors fix your problem but I would be a little skeptical also. To me this sounds more and more like the problem early Ford Ecoboost motors we're having. Condensation is building up in the intercooler and under full throttle enough water is being sucked in to cause a misfire.

If this is the problem then the solution Ford found was to block off part of the intercooler with a metal plate as it was cooling the turbocharger air too much, causing condensation. This of course would lower the advertised HP the engine can generate. Bit of a damned if they do, damned if they don’t. The designers of the 3rd Gen RDX were pushing too hard to have a comparable HP number compared to the 2nd Gen RDX and this is what happens. At least the RDX woes seems better than Volkswagen IV turbos which can completely flood and seize the engine in Canadian winters.. it is crazy watching YouTube videos of people disconnecting the hose and letting the water out.

I've had our new RDX for 1 week and unfortunately had my first limp mode incident. I was accelerating onto an onramp and decided to floor it to get up to highway speeds. The car immediately went into limp mode and I limped to the next exit at 40 miles per hour. When I took it in, there was a temporary DTC of P0301. "Please advise guest that this could possibly be from some bad fuel. Suggest making sure that the guest gets good fuel at a known good reputable gas station."
#303
Well the cause is definitely not the bullshit response you got from Acura. If they have canned responses already lined out due to the numerous issues it would seem likely they know or have a good theory what the issue is.
#304
I got my car back yesterday and they also replaced the high pressure fuel line as well as the fuel injectors. It’s funny because several people at the dealer asked if I started lemon law on this car yet 😂

Thanks for your post. I also have an 2019 Advance mostly driving in Comfort mode, i have a quick question re: the ride quality of this vehicle. I have a feeling that this car ride is too bumpy. Do you have the same feeling? I thought of reducing the air pressure from the 4 tires down to 32PSI but still doesn't know if this is advisable or not. Any thoughts from you please?
Thanks-in-advance for your reply.

It is not advisable to run the tires below the recommended pressure, because excessive flex of the sidewalls at low pressures may cause the tires to overheat and fail, perhaps catastrophically. ( Remember the Ford Explorer/Firestone debacle? )
An exception can be made for short-term low-speed operation in sand or extremely slippery conditions, but the tires should be re-inflated to spec for highway use.
If you want to run tires at a slightly lower pressure to improve comfort, consider purchasing a tire/wheel package with a higher profile tire, such as 235/60R18.
But really, if you don't like the sporty suspension of the 2019 RDX, you might be better off trading for a different vehicle. It's part of the package.

Thanks Wander for your advise post. Truthfully i was considering trading it off but it's just over 6-mos and i'm not sure how do get out of a lease this early. Perhaps other(s) might be giving me some ideas? Thanks all-in-advance.

Major issues with my 2019 RDX!

Basically just take it to any dealer of the next car you want and trade it in! My previous 2 leases I traded in early because I wanted something different.

Null and proud of it
My car actually slams on the brakes going over 60mph to a dead stop. I have to put it in park and then drive again before getting it to go in the middle of the road!! I have had it happen 8 times with it being in the shop numerous times with them always saying “sorry but we can’t duplicate the issue.” Also, my infotainment screen is solid black or crazy lines thru it. No radio controls, no GPS, no backup camera, etc. Acura customer service was 0 help! The dealerships just keeps resetting the system. It will work fine for 1 day then will go back to a black screen. I am on day 38 of a nonworking screen! I finally had to hire a experienced Lemon Law lawyer, which is what we are dealing with now. I also feel so unsafe in this vehicle!
Holy crap. I feel for you.
How many dealers have you visited? It may be of value to visit a different dealer.

2019 RDX Limp Mode
I figured I would share this info about our RDX going into limp mode over the weekend. Our vehicle is the A-spec model with 9,200 miles currently. I was making an early morning airport run and the vehicle was running for approximately an hour before it went into limp mode as I am driving on I-85(Atlanta). I did encounter a good downpour of rain on the way down to the airport from my home, but on the way back the rain had stopped and the road was fairly dry. Now to the issue at hand, I was passing a slow driver in the left lane, I accelerated and passed the vehicle and after merging back into the left lane I noticed immediate loss of power. I didn't realize for 10 seconds or so that vehicle's check engine light was flashing in the bottom righthand corner of the gauge cluster. I then begin to merge over 6 lanes of the interstate as the RDX's power drastically declined and I could not apply throttle past 2k RPM. Luckily there was minimal traffic(6:30am) and I was able to safely exit the highway. I pulled into a near by Quicktrip and turned off the vehicle, waited a few minutes or so and turned the vehicle back on and went about my way home without any further issues. I call my local dealership where the vehicle was purchased from this am and of course no one picks up. I decide to head down and report the issue with service dept. and have them look over the vehicle to figure out the issue. This is my 2nd trip to the dealership in a week, I had the window trim replaced and infotainment system checked out because it wouldn't turn off during a previous trip and I had to press a bunch of random buttons to get the system to reset. Anyhow I will report back on this thread to what they find out at the dealership, I am assuming they won't be able to replicate the issue as that is standard protocol amongst all dealership nowadays
Ohh, I almost forgot to mention the service advisor advised me not to use the CarPlay system until a software update is released by Acura because it cause other issues with the vehicle.. WTF, I told my service advisor to have Acura refund me a portion of my monthly payment due to them selling me a vehicle with constant infotainment issues.. SMH! I also advised him the vehicles ECU which controls the engine and transmission shouldn't have anything to do with the infotainment software.. Come on ACURA figure out your S***!! My wife and I love the RDX, but the infotainment and now the limp mode thing is really leaving a bad impression of the current state of Acura(coming from a Acura fan boy)

Update: Dealership called me this morning and stated no fault codes stored, so I am SOL(I predicted correctly in my original post).. I spoke to the SA and SM and voiced my displeasure about the whole situation. I advised them that it is complete BS that they are feeding a customer the standard line of no fault codes stored, so nothing could be done to my vehicle to investigate the problem. I also stated this is my wife's vehicle and she travels on the interstate daily and the diagnosis they have provided me so far has left me with little faith in Acura brand or their service department. They did offer to keep me in the loaner vehicle and do some extensive test drives with our vehicle to replicate the issue. I advise them per the Acurazine forum the issue seems to primarily occur during humid or raining conditions(which was my scenario) and just my luck we have no rain forecasted for the next 7-10 days in the Atlanta area. I advised the SM and SA to read the pages that are documented on the AZ forum and hopefully develop a clue as to what is going on with these 2.0T engines in the RDX. I advised them I will call once there is some rain in the forecast to schedule an appointment. I picked up the vehicle put it immediately in sport+ and floored it at every single traffic light on my journey back home this am, just to see if it acted funny in anyway, nothing occurred, but it was a enjoyable ride home .. I will report back to this thread, if I do decide to take it back in for the SA/master tech to drive around my vehicle for a few days.
