As I'm slowing to a stop. Do other people hear it? I could have sworn that for the first 2k km or so I didn't have any regen whine. Now it is there all of the time as I slow from about 50 km/hr to dead stop. I'm curious if I just started hearing something that was always there?
BTW, I love my car. It's the perfect sleeper car. And that suits me just fine
Yes. And another side effect of how quiet this car is that we can hear some whine from the electric motors. It does mention it in the owner's manual that some sounds uncharacteristic to most cars may be heard. Frankly, I think it kinda cool to hear it, reminding me how sophisticated this car is.
I rarely feel any lugging of the regen as I coast (no throttle) slowly though neighborhood roads (
Yeah. I hear the sound of the electric motors too. And this is a very sophisticated car. I have a big hill to descend on the way to work. I love riding the brake all the way down knowing I'm generating no brake dust and lots of battery power. Does anyone else notice the lack of brake dust? Does anyone know what happens to excess regen power once the battery is full? There must be a way to dump this excess energy.

or lurking for a parking space. But I do notice electric motor lugging when reversing up my driveway and into the garage. This only happens when in electric only mode.
Dunno why my first post got truncated, so I completed my thought in this post.

I believe the EV motors have a switch that keeps the batteries from being over charged, but I have no idea how that happens. I think our friend pgeorge can help us with his fancy charts and graphs!
My car gets cleaned so often it never has a chance to collect brake dust. It is sparkly clean right now with a fresh multi-step waxing treatment and interior detail to boot. It looks factory fresh with 21,000 miles on it. Even the engine is clean, the inside of the wheels and the suspension parts too. I did the same thing to my MDX also today. It is more challenging in the cold so I put heaters in my garage so I can detail in the winter. Like I have said before I am a little eccentric with the detailing stuff. Cheaper than drinking and therapy.

I have the same thing, but putting it in sport mode resolves the issue. Just make sure to appreciate the throttle so you don't put into a wall. Have I mentioned how sneaky fast the Blackbird is? Lots of fun.
Oh man do I know how sneaky fast this car is! I also love the plentiful torque. It's really quite effortless to drive. And keeping up with traffic is never an issue. Sometimes I have to force myself to keep pace with traffic
It really is a chameleon when you press the sport button.
I don't know if I'll get into trouble for meandering from the initial post, but can anyone tell me about maintenance? The car indicates 60% oil life left and I'm at 7k km. At this rate I will be ready for service at over 15k km. I called the dealership to ask about scheduled maintenance and he told me to bring it in every 7k km. Any advice?
The car will advise when it needs service in the MID display. The service codes are in the manual for what needs to be done. The car computes service visits based on your driving style and use. It will also bundle service needs so you need not make multiple service stops.
Last, don't change out the initial oil too soon. There are additives from the factory to help with the break in and conditioning of the engine. The dealer would service your car every week if you allowed. Follow the car's service advisement and you will be fine as well as save a bundle in unnecessary service calls.

My experience is that I got my first service at just under 10,000 MILES. it was just an oil change and maybe a tire rotation. I now have 13,000 miles and am at 60% oil life.
Your mileage may vary depending on your driving and perhaps the weather conditions......your colder climate probably has some impact on the frequency of the oil changes.
Don't listen to your dealer. As mentioned above some dealers want you to come in for service not because you need it but because they are looking for revenue. For years dealers and manufacturers set a minimum mileage threshold for oil changes which was the lowest common denominator. Some dealers, yours is apparently one of those, try to play on this outdated paradigm rather than take into account today's longer lasting oil and sophicated monitoring systems which can determine the need for service based on how each cars is driven.
BTW- Welcome aboard. Great to have another Sport Hybrid owner on board. Look forward to hearing more questions/comments from you. You will find lots of support and help from the denizens of Acurazine.
I think this explains pretty well how the charging and discharging is handled. I can also post the explanation of the Twin Motor Unit itself in detail, if you guys would like.
In my old TL SHAWD I think we had to change the rear diff fluid at 15k and then every 30k after. Is that the same thing with the RLX-SH? If so is that a dealer only item?
pgeorg, that was awesome... thanks! I did a little more research and there are several ways a regen system can dump excess power. One is to switch to friction braking (in effect limiting the amount of regen power input). Another method is to generate heat (which requires a cooling mechanism), and the third method is the electric motor can spin up the ICE without gas. And this latter behaviour is what I get going down the big hill. The engine starts, but when I look at realtime fuel usage, it is 0. I also notice the rear wheels indicate no regen so I'm guessing they switch to friction braking.
I would't let anyone near the TMU except Acura. And even then, dealerships service so few of these cars I hope they get it right the first time
I am fortunate that the tech who has serviced my Acura's (and only he) has been certified by Acura to service Sport Hybrids (including the NSX). Chances are the techs trained for Sport Hybrid service are the elite techs of the dealership.

My tech is an Asian dude who looks like he designed advanced weapons systems and speaks in a language that I think is English but coded in advance auto technical jargon. He is my Blackbird Sensei so when pgeorge can't provide guidance I speak to him. I spoke to him on Thursday about my little rattle in the front end since he was the only one who has touched my car other than me since my purchase. He wants to look at the sway bar links on the RLX-SH as he is also going to do the repair my new MDX with the same situation on the rear of that vehicle next week. Maybe our issues we have been plagued with are not in the shocks but the sway bar set up? Does that make any sense?

Words don't come close to describing the experience of driving the Sport Hybrid. The combination of the electric motors and the gas engine provides a unique feel to the car, yet one that most of us find very enjoyable. A test drive is the only way to understand what we are talking about, however, be warned that it is hard to resist to the urge to buy one once you have had a good test drive.
Yesterday, I had a rather expensive A-1-2 service performed.
I hate to be suspicious, but the whine is reduced.
0_o
290.00 included some fluids I'd never heard of before.
Is it possible to be a little more specific, George? I looked at the maintenance schedule, and there are no fluid changes (except for the engine oil change) for A-1-2.....
It's interesting about the perception of a sound once it's entered ones's consciousness. I'm trying to focus on the positive aspect of what the noise is doing, converting dynamic to potential energy waiting to be released when I next step on the gas pedal... or more precisely, the accelerator pedal, since gasoline isn't always involved these days. Oh, and if a passenger asks what is the whine in the car I usually respond with their name
I just switched the rear turn signal bulbs to led. Since the rest of the car has led lighting, why the heck Acura decided to use incandescent rear turn signal bulbs is puzzling. I like the crisp on/off; it fits in with the rest of the car... I'm toying with led reverse lights. It can't hurt to have more illumination when one is backing up.

I did that and I am pleased with the results. Change the trunk lights as well for very improved results. I also changed the fuse bulbs in the vanity mirrors to LEDs (some may think these would be too bright w/ LEDs). I have yet to get the 4 door puddle lights swapped out. I have the LED bulbs, but the power line to the lens covers has so little slack I have not had success getting my fingers to pop off the sockets so I can swap the bulbs for the LEDs. The puddle lamps at the bottom of the 4 doors are way too dim to be useful.
Yes. On the bottom edge of each door. Hence they only shine on the ground when you open the door, not as you approach the car. And by your response, you affirm they are too dim!
