Have you/anyone found a solution for this issue? It happened to me twice this weekend in my Advance SH-AWD. Both time I was doing about 75 mph with ACC on. I went to accelerate and the car lost all power to the peddle and the check engine light came on. I managed to make it to the side, turned off the engine, and turned it right back on and the car seemed to run normally. The events were 3 days apart. I took it to the dealer today and they state the car didn’t throw any codes and they can’t reproduce. They are keeping it overnight to do more diagnosis tomorrow. I’ve read the thread above and can state the battery was charged, I’ve got about 2000 miles on it, and use 91 octane non-ethanol Top Tier fuel. Frustrating….

I have a AWD A-Spec RDX with 1500 miles. Yesterday morning (Sunday) I tried to pass another vehicle and the car went into limp mode. Since this is a new car, I had AAA bring it to the Acura dealership. When the technician reviewed the codes, a "few undefined" codes came up and they reset my computer then drove it 15 miles with no problems. Now my stop idle function is not working. The dealership want to look at my car tomorrow to diagnosis the problem.
I'm hoping that my new RDX is not a lemon. Glad I found this website which is helping my feel better about this problem...

They might think they are going to lose and want to make sure they get paid for their efforts. I don't think the manufacturer's pay your attorney's fees if you don't win the case.

No, the few I talked to gave the option of the federal lawsuit. Basically they work for free and don’t get paid unless we win the case. If we win they get paid, if we lose they get nothing. I’m not responsible for any attorney fees

I just checked the safercar.gov site. They have added 6 new AHM communications, but none regarding this issue. I did call NHSTA on Monday, but they were of no help with the limp mode issue besides telling me they were “investigating” my complaint and the others.

i have my 2019 rdx aspec with a intercooler and rv6 catted down pipe. I was accelerating and my car did a weird shift check engine light came on and was flashing. Could not accelerate anymore pulled over had all cylinder Mia fire codes. Cleared them and nothing yet only went 4 miles since it happened. I’m a tech at a Acura dealer in the Bay Area so time to dig into why it happened. No way bolt ons should effect that. Only thing I’m nervous about is I just filled up the gas tank. Hope it’s not bad gas. I have had the mods on for 900 miles no problems. Will give updates.

Recent conversation with my "young adult" daughter ( summarized for brevity and relative clarity ):
Daughter: "My foot hurts."
Dad: "Didn't you go dancing in high heels recently?"
Daughter: "Well, yeah, but there's no way it could be that... maybe I need an MRI".

I'm in the market for a RDX and can't believe there isn't more coverage about this issue. Have there been any updates as far as fixes? I was looking to get an RDX by months end but I might hold off my purchase if this isn't resolved.

No updates for the pcm yet. The dealer I work at I’m the first that had the issue. The amount of cars produced to the amount sold it is very little failure rate with this issue. I asked the rep about it and said all his dealers I’m the first he heard of in northern ca that’s reported the issue.

I second the dash cam option. There are ones that records both inside and out. Get it on video, share with dealer and post on youtube, tweet and IG with appropriate hashtags.....
Nothing beats bad PR to get a response

2019 A-Spec. Same exact situation. Car has been at the dealer for about 3 days. Have been extremely pleased with this service department for both our TLX and RDX. Tech saw the video and sent it straight to Acura. Pulled a few misfire codes. They are leaning toward a bad coil pack, but more to come. I had to approve them holding the car for an extended period of time so they can do load testing and also test drive the car with new parts in the same condition.
Gave me a 2019 Advance to drive in the meantime.

Ya I feel like no real problem with any parts. It’s more of a software issue and gets a reading that faults it. I have tried to drive it the exact same way when it faulted every time I drive it and can’t get it to fail. I keep following it and looking for any info online with Acura but it’s not happening to a lot of cars. Changing parts with a not verifiable code is a waste of time and money.

It’s been 2 months now since I filed my complaint with NHTSA. The OP of this thread was last July. Obviously, Acura still doesn’t have a clue about a fix since it’s rumored Acura monitors sites like Acurazine for pros and cons, and especially problems.

Ya but Honda always keeps things on the down low till they have enough complaints or a fix. I don’t see some recalls until the day they come out. No heads up or anything.

If it helps to calm everyone's mind. I had my limp mode last year at around 600 miles on the odometer, dealer kept the car for a week and can't find any problem. Dealer said there was no code.
I took the car back and now I am at 11,000 miles. Limp mode never happen again. Also, I use regular gas, and I drive the RDX kindda hard..
Not an excuse for Acura, but at least it didn't happen again for me.

Given the number of reports of the RDX here and on the 4 complaints on NHTSA going into limp mode under similar driving (at speed) conditions I’m still leaning toward a software bug. I’m sure AHM has run computer simulations, but it’s a daunting task from what I’ve heard from a program analyst I know. You could be looking for the proverbial needle among mind boggling lines of code written by dozens of programmers. I’d just like to hear something from AHM acknowledging the problem at least.

This is why I love this forum so much. One stop shopping for getting real owner/driver feedback on problems and fixes. This site has an amazing DYI library. Although it may not appear for this problem, if an owner finds a fix or a work around, it is usually posted here.
Just hoping that this and the infotainment bugs can get worked out soon.

Just heard from the dealer. They kept it for almost a week. They pulled misfire codes and went ahead with replacing all coil packs and plugs. They could not replicate the issues after replacing these parts (shocking). Hopefully never experience this again.

Safercar.gov updated info about the RDX—a new complaint about AHB, but nothing about our limp mode issue. It’s seems AHM is most concerned about the timing chain cover leak on the RDX.

Update: Disclaimer: All that follows is hearsay at this point in time: The #1 cylinder is “overloading” to cause misfire and subsequently limp mode. Replacing all fuel injectors (OEM or others I do not know) is an interim (expensive) fix until an official/permanent solution is released. Any repairs must be authorized thru AHM after verification of a certifiable initial complaint. In other words, you can’t go into a dealership demanding new injectors after reading this post. Believe it or not!

I have 15,000+ miles on my RDX A-Spec and have never had limp mode, but now I am going to be looking for it. So if it's raining or damp I should behave and not try any quick acceleration on the highway, or at least be prepared for this. I don't know how I missed this thread earlier, but wow. What a read!

Another owner’s complaint has posted on safercar.gov on April 9th. Unfortunately, I think there are individuals who make fictitious complaints, which hinders the investigation into real problems reported by owners.
Update: Since I’ve not heard back from the service manager of my selling dealership several weeks ago now, I’m assuming he was not able to convince the Acura dealerships near me to replace the injectors as a courtesy since it’s not an official fix. I’m sure he is sick of me calling, texting, and emailing him, but I want this fixed, and fixed right the first time.

Yet another limp mode incident report to NHTSA yesterday, April 18th. Of course, nothing from AHM yet.
I AM SUBMITTING THIS TICKET TO DOCUMENT A HAZARDOUS SCENARIO THAT I HAVE EXPERIENCED TWO TIMES SINCE PURCHASING MY BRAND NEW 2019 ACURA RDX. INCIDENTS OCCURRED WHILE DRIVING IN OHIO AND PENNSYLVANIA ON COOL DAYS (AMBIENT TEMPERATURES BETWEEN 30 AND 50 DEG FAHRENHEIT), WITH AND WITHOUT RAINFALL. THE FOLLOWING CONDITIONS WERE TRUE FOR BOTH OCCURRENCES. WHILE DRIVING ON AN INTERSTATE HIGHWAY WITH ADAPTIVE CRUISE CONTROL [WITH LOW SPEED FOLLOW] AND LANE-KEEPING SYSTEMS ENABLED, I DECIDE TO OVERTAKE A SLOWER VEHICLE AHEAD OF ME. I DEPRESS THE ACCELERATOR PEDAL WITHOUT DISABLING THE CRUISE CONTROL FUNCTIONS AND CHANGE LANES TO THE FASTER LANE. JUST AS I EXECUTE THIS MANEUVER, THE ENGINE SIMULTANEOUSLY GOES INTO LIMP MODE -- THE MAXIMUM POWER OUTPUT DECREASES DRAMATICALLY AND THE MALFUNCTION INDICATION LAMP (CEL) IS BLINKING. AT THIS POINT I HAVE TO GET ACROSS ALL LANES OF THE HIGHWAY TO PULL ONTO THE SHOULDER, AND I HAVE TO DO THIS WHILE THE VEHICLE IS SLOWING DOWN. REFERENCING MY OWNER'S GUIDE, I SEE THAT THE BLINKING CEL INDICATES A MISFIRE IN THE ENGINE'S CYLINDERS IS DETECTED, AND AS INSTRUCTED I TURN OFF THE ENGINE IN A "SAFE" PLACE AND WAIT FOR THE ENGINE TO COOL DOWN. WHEN I RESTART THE ENGINE, THE CEL IS CLEARED AND THE VEHICLE RESUMES NORMAL FUNCTION.
I TOOK MY VEHICLE IN FOR ITS FIRST SERVICE APPOINTMENT YESTERDAY. I PROVIDED THIS ANECDOTE TO MY SERVICE ADVISOR, AND ASKED THAT WE CHECK ERROR CODE LOGS AND INSPECT COMPONENT SYSTEMS FOR DAMAGE. I WAS INFORMED THAT THERE WERE NO ERROR CODES LOGGED, AND THAT THERE SHOULD BE SUCH A LOG IF, IN FACT, THE CEL WAS INDICATING. ALL COMPONENT SYSTEMS PASSED INSPECTION/DIAGNOSIS.
I AM ATTACHING A PDF CONTAINING THE FULL DESCRIPTION TEXT OF THE TICKET SUBMISSION THAT I HAVE MADE TO ACURA CLIENT SERVICES.

A couple of days ago, on April 19th, my wife and I were driving through Columbus, GA. It was around 7:00 AM and raining. We had been driving about 1 1/2 hours and we were only going around 30 MPH when I accelerated to pass a dump truck. The 2019 RDX (6000 miles) started accelerating and then lost all power. I was able to limp over to the side of the road without getting run over by the dump truck but it a was very scary couple of minutes. I turned the RDX off for a minute, restated and then continued our trip. I took the RDX to the Acura dealer in Macon the following day and even though the check engine light came on no codes were stored. The service department did a hard reset of the system hoping to fix the problem. They seem to think that Acura is coming out with a software fix soon but that always seems to be the standard answer. I'm now afraid to let my wife drive the RDX. I had previously thought that my biggest problem with the RDX was the Android Auto no show. Acura needs to fix this problem ASAP before someone gets killed.
