..and neither does the Accord.

This video proves it, but only once.

In regular 'D' mode, and 0-60 test was performed twice. One time the car shifted fine, the other it held on to second for dear life.

RLX 0-60: 6.0-6.3 seconds.

Accord 0-60: 5.5-6.0 seconds.


tedimansour1, the owner of the 2013 Accord EX-L V6 6AT says in the comments while replying back to me that his car wouldn't leave 2nd gear after doing a acceleration run and it shut off on him and he couldn't get it started till he put the car in neutral. The RLX didn't shut off. Both cars use the new EarthDreams tech which consists of the J35Y V6 and 6AT. I believe its the 6AT's mapping is at fault, since the RLX's J35Y3 has direct injection and a whole different ECU. The Accord J35Y1 does not have direct injection. I wonder if the 2014 Acura MDX will do it as well, with its J35Y5 V6 and the same 6AT? We'll see I guess.

Both cars use the same 6AT, despite the RLX's 6AT having slightly different gear ratio's; says Acura.

I have only heard that the Accord has done it once and the RLX in the video only showed it happening once, so maybe it was just a hiccup in the 6AT's mapping that only takes it once to happen and fix its self.

Both cars a pretty quick, especially the RLX for what it is.


Just a heads up for you guys. Not trying to draw you away form buying one. I just kinda wanted to be the first who posted about it here with proof.

 

I hope everyone is aware most modern cars have dynamic ECU and AT mapping support. That is, depending on how you drive the vehicle, it dynamically adapts to either a more passive, high-mileage or an aggressive, 'sport' mode, holding gears longer, remapping the ECU for more output, etc.

So once you flog it once, it 'learns' that you are looking for 'performance' and shifts mappings.

So for a test like this to be valid, you first have to run them like you stole them, then stage a test.

 

Yep modern ECU's learn driving for sure. I drove a friends of mine Camaro SS that he babies and it is a slow car. Mine kicks his butt all day like but I drove her like a 400rwhp car is mean to be driven. My back tires hate me.

 

Correct, and I pointed that out in my original post. Transmission mapping failed to switch gears. The engine's ECU did cut fuel and ignition but it came back as if it was in 3rd gear. It then bounced off the limiter and the transmission said "Oh wait, i'm in the wrong gear" and then switches.

It learns. :P

Only problem I see with this is when new customers come into the dealers to buy one and take it for a test drive, gunning it to 60 for fun just to have it redline like hell and make them think the car is faulty. After done once it shouldn't happen again so they would just be thinking a perfectly good car is no good and skip it and the rest, probably going to a different brand.

So Honda and Acura dealers better 0-60 every car before we do! haha

 

It is weird to see that happened. I dont normally drive like that and will probably never try that. So I don't really care.

I have my RLX a little bit more than 2 weeks. It is very smooth and comfortable.
I am waiting for 1000 miles oil change will be done in about 2 more weeks then I can have some more fun .

 

In my experience we saw none of that. Something to watch for sure.

 

Those particular RLX have probably already been 'broken in' or maybe they're just not at certain period in code to get stuck. Perhaps it has something to do with all the environmental influences and the right combination causes it. Who knows. I'm sure there will be a Acura and Honda Recall in the next few months.

 

1000 mile oil change??? You are going to Ruin the car.

 

First 1000 miles service was scheduled by the dealer.

 

seanlin,

Recommend getting a second opinion on changing the oil at 1,000 miles. Unless Acura has a new approach for the RLX, they have always used a special break in oil that is supposed to remain in the engine for several thousand miles. The engine can't get the full benefit of this oil at only 1,000 miles. A change now might be detrimental to the engine. Follow the MID, not the dealer.

I would at least consult the owner's manual.

 

1000 mile service? At that rate, I'd buy the car and be back at the dealership after a weekend...

 

Will your RLX now shift under load consistently?

I'm having this issue but sometimes it will fail to shift until I slow down 10+ mph or come to a near dead stop. - mine has failed to adapt and learn to shift - 4000+ miles on the vehicle . It happens @ 60%+ throttle and only in 2nd gear attempting to shift into 3rd.

Did you ever bring it to the dealer to see what they said?
