Limp mode 2019 A-Spec

Almost every instance I have read here about this has been people feeling the need to pass someone while already doing 70+. I don’t know where everyone lives but most highways I drive are 70 speed limit tops. The need to mash down the pedal to pass anyone is rare. It’s aggressive driving and probably just as unsafe as the car going into limp mode anyway.
im not making light of the fact that it’s an issue and scary and yes could have very bad results, but I do question why people feel the need to drive so aggressively. Maybe I’m sensitive to it being in Delaware where hundreds die every year on rt 1 as a result of people doing 80-90+ on roads that are limited at 65 which is honestly still too fast given the volume of traffic and the lack of barriers in the medians.
Sorry if if I offended anyone or made you feel like your issue isn’t serious.
And below Richmond on 95, the speed limit is 70 most of the way. Car should not react like that at 70 mph.

Yup...agreed.
The car has a govenor-limited top speed of 113mph. So the excuse that it's "shutting itself down to protect itself" at 70-80mph is pretty far-fetched.
Also, let's not forget this car has an automatic transmission. If the car was programmed to "protect itself from damage" at higher accelerations it would up-shift. If not, than again...it's a design flaw...not user error.

I think the point of limp mode is to prevent over revving the engine and blowing it up. So at 70 mph when you try to slam the pedal to the road beneath the car, it trips the breaker so to speak as a way of preventing a hard Downshift and over rev. At least that’s my understanding of it. It’s technically working the way it should so that’s why no codes get thrown. But it appears to be more sensitive to some owners. Keep reporting it though. If it’s happening under so called normal conditions then it’s an issue. But I stand by my point about slamming it to the floor. Be gentle 😝 . There is plenty of juice in this car. 280 something ft lbs of torque right?
All modern car engines have various mechanisms to prevent the engine from over-revving, but none have any mechanisms to object to the user demanding the maximum power the engine was designed to produce, which is typically produced pretty darn close to redline. Most cars sold in the USA do have speed limiters that will roll off power when you approach a designated maximum speed.
Most of the time, the transmission controller will force an upshift and the engine controller will gently roll off power for the shift if you are accelerating and rapidly approaching rpm "redline".
If you do manage to trick the transmission and engine controller into a "hard-hit" over-revving situation ( as can more easily happen in cars with manual transmissions or less intelligent ATs ), the engine controller will get more aggressive with cutting fuel and whatever else it takes to protect the engine from excessive rpm ( NOT excessive power ). This is called "bouncing off the rev limiter" because that's what it feels like. If you are silly enough to stay "on the gas" the engine will cut out until it drops below redline, surge forward again, and repeat until you get a clue and lift your right foot. It sounds and feels terrible, but the vast majority of the time the engine protects itself, no "codes" are thrown, and life goes on.
[ One situation the engine controller may not be able to control is an over-rev from engine braking down a descent. That's up to the transmission controller. And/or the idiot behind the steering wheel. ]
"Limp mode" should only be invoked when a "trouble code" has been generated by the engine controller, and that should NEVER HAPPEN in normal operation, including running the engine right up to redline. If codes are getting thrown from accelerating on the highway, something is wrong. If "limp mode" is being invoked, something is wrong. End of story.
Whether that "something wrong" is a messed up transmission controller that is allowing downshifts into an over-rev condition, is a relevant question. But so far, there has been no documentation of that.

Rev limiters and "limp mode" have almost nothing to do with each other.

Joking aside, I guess my question then is if this isn’t supposed to be the way limp mode works then why are dealers just dismissing these reports? It would seem pretty obvious that something isnt working right despite the no code and one would assume that Acura would know relatively easily and quickly what would be at fault for it....sort of sounds to me like the computer that comes controls this system needs an update.

Precision crafted performance (as long as you don't ever plan on driving over 70 mph). You gotta read the fine print on these things...lol
It's pretty hilarious that someone would actually try to defend a brand new car going into limp mode because you tried to accelerate and pass someone going 70 mph. Something is seriously wrong.

Hello. I have filed a formal complaint about this issue with NHTSA. Read it online in a couple of days. It was a very harrowing experience to say the least. Acura dealership was clueless, but I have been told by a little bird Acura is investigating albeit on the QT.

The little bird said the problem “might” be the fuel pickup in the gas tank, but the whole tank was removed for investigation on the RDX they were told about. I was also asked by the little bird it is was raining when my limp mode occurred; it was. Strange. I hope this is resolved before someone is seriously hurt or dies. My wife and I were very close to causing a major wreck.

So, let me get this straight: travelling at high speed, about 70mph, and a demand for significant power is made.
The transmission downshifts? Revs go to over 4K, and then limp mode?
I am driving to Florida in a few weeks, and 70mph is a pretty standard speed. You also sometimes need a burst of power.
Am I getting this right?

Yes. It’s a weird feeling. You floor the car and it downshifts, but the power just isn’t there. It feels like you’re driving a car with half of the power. The car starts shaking and you go into limp mode. When you go into the limp mode that is when the check engine light starts flashing. By then you better get over ASAP because you aren’t able to go faster than 10 mph in limp mode. A restart fixed it the second time it happened to me, but the first time a restart didn’t work and I had to tow it in.
This is little birdie someone was talking about who wasn’t investigating this issue... is there any inkling of what it is? The reason I ask is that I don’t want to own this car if this is going to be an issue with no fix in sight.

I’m in limbo mode right now. I picked up my car from the dealership. They sent of the computer records of the car? To Honda in California. The dealership said they should hear back on Friday if they want to look at the car further or basically not to do anything. If it comes to the not do anything, my first step will be to call Acura customer service.

This could be a totally different problem but the early Ford 3.5 Ecoboost motors were notorious for this issue. Ford had to make a modification to the intercooler to fix it.

Dealership called and.... surprise! Those engineers didn’t find anything in the computer code or any other known cases of the issue. I called Acura customer service and started a case. Hopefully I know more soon.

I opened a case last month. All Acura did was call my service manager to verify no codes, and left me a message saying they will make note of the issue. I called back to ask what would cause limp mode in general, I never got a response.

If all it takes is a momentary engine misfire to trigger a full "cripple mode" of the vehicle, it seems like Honda/Acura is being overly protective of their engines.
It could be something as simple as condensation on the inside of the air intake getting dislodged and sucked into the engine with the increased airflow of higher rpm operation. The engineers can examine their computer code all they want, they won't find that.
Back in the day, I drove my Dad's carburated International Harvester Scout Traveler ( look that one up, 4WD geeks! ) and that thing would stall nearly every time I punched the throttle to turn onto a 2-lane major truck route near my family's home. So then I'd be wrestling the thing onto the gravel shoulder at low speed without the benefit of power steering, as an 18-wheeler approached at about 75 mph. Good times. That was a problem with the completely analog fuel delivery and vaporization system.
With our 1st-gen MDX(s), when the oxygen sensors get a bit flakey with age, the things occasionally throw a code, illuminate the "Check Engine Light" and "VTM-4" light, and shut off the AWD system. Mr Murphy demands that this happen in a snow storm. The engine is running fine, it's just a potential emissions problem. There is no problem with the AWD system. So, WHY SHUT DOWN THE AWD?!!!! ( Pet Peeve )

Following is my post from NHSTA/safecar.com. I encourage every member who has experienced this issue to complete a complaint form ASAP. Otherwise, Honda/Acura will take its time to respond/investigate. Right now it’s just one old timer, who they probably think is making things up.. There is strength in numbers.
MY RDX WENT INTO ?LIMP MODE? (30 MPH MAX) WHILE ON I-75 SOUTHBOUND IN MODERATE TRAFFIC NEAR MACON GA AT 10 AM TRYING TO ACCELERATE TO SPEED LIMIT (70 MPH) FROM 50 MPH AFTER BEING CUT OFF BY AN INATTENTIVE DRIVER. ENGINE MALFUNCTION LIGHT WAS BLINKING. GOT TO RIGHT SHOULDER SAFELY AND TURNED ENGINE OFF. RESTARTED ENGINE AND COMPLETED ANOTHER 400 MILES AT INTERSTATE SPEEDS WITHOUT INCIDENT. ACURA DEALERSHIP COULD NOT REPLICATE PROBLEM, NOR WERE ANY CODES STORED ON OBD. I WAS TOLD BY ACURA SERVICE WRITER TO MONITOR ENGINE PERFORMANCE AND REPORT ANY REOCCURRENCES. SEVERAL ACURA RDX OWNERS ARE REPORTING SAME PROBLEM ON A POPULAR ACURA ONLINE FORUM. ONE MEMBER STATED THE HONDA CIVIC TYPE R IS EXPERIENCING THE SAME PROBLEM. THIS IS A VERY SERIOUS ENGINE AND/OR ENGINE MANAGEMENT DESIGN PROBLEM NECESSITATING AN IMMEDIATE INVESTIGATION AND RECALL, IN MY OPINION. RIGHT NOW I FEEL MY RDX IS UNSAFE AT ANY SPEED WITH THE POTENTIAL OF CAUSING SERIOUS INJURY OR DEATH.

So, a little update. The dealership the car is at found codes stored in the computer. The same codes it threw the first time it happened. The last update I received was that they are waiting for someone to tell them how to fix it. Acura client relations and the dealership are actually being very helpful right now surprisingly.

I had a 2013 Hyundai Veloster Turbo and under certain high boost, high rev conditions it would go into limp mode. Many, many owners had the same issue. Hyundai eventually figured out that one of the rubber fuel lines was collapsing under the extreme draw of the high pressure fuel pump. starving the engine of fuel and causing the limp mode. They replaced the line on affected cars and implemented the new part into the new builds. Never had an issue again after that.
To those of you having this issue (or even other ones), a wise and cheap investment might be an OBD2 dongle and an app like Torque or Dash Command for data monitoring and logging info.

I just spoke to the service manager at my selling dealership. He told me Acura is aware of the problem now and working on a fix. The problem is a sensor sending faulty info to the ECM. There will be an OTA system update, but date unknown. He told me to check the system update icon on the nav screen frequently and update via Wi-Fi when the time comes, or take to an Acura dealership and have them update it. BTW, I’m still getting the screen that my maps are out of date, so I’m taking everything I’m hearing with a grain of salt. I also called Acura Client Relations back. They were clueless, but again told me they were sorry if I felt the RDX was unsafe. I asked if they had specific info about the issue, but was told they didn’t have access to anything like that, and engineers don’t take personal calls. So, it’s wait and see and hope the fix is indeed a fix, or not.

Urgent ECM Update
Has anyone received the OTA notification yet of the ECM update concerning the “limp home mode” issue on all 2019 RDXs? I posted new info today in the “Problems and Fixes” section of this forum within the tread started by 2019ASpec last July. With such an important safety issue I was wondering how Acura is going to inform all current owners about the update if they ignore the update icon.

Has anyone received the OTA notification yet of the ECM update concerning the “limp home mode” issue on all 2019 RDXs? I posted new info today in the “Problems and Fixes” section of this forum within the tread started by 2019ASpec last July. With such an important safety issue I was wondering how Acura is going to inform all current owners about the update if they ignore the update icon.

The more I hear about Acura client relationship the more I feel it is just a therapy call center, powerless and without real info. It is just human voice to tell you everything will be alright......

Going to a different dealer isn't always trivial. In my mid-size and growing city there is one Acura dealer and two Honda dealers. The next closest Acura dealer would be about a 1.5 hour drive. After that, about 3 hours.
