This is the highest mileage I've seen on an RDX, since they've only been out since Model year 2007 it might be hard finding one with higher mileage. Speaks good things about Acura's first try at building a turbo engine. This dealer is only a few minutes from my house so I'm curious to see what it looks like in person and under the hood. If anyone is short on cash it's good to know you can pick one up from a dealer for around $13k.

I'd be curious to see if anyone knows of a higher mileage Acura RDX.

That is pretty quick.

We are on pace to be at 140k in six more yrs.

We racked up ~20k in our first RDX yr. Its all we want to drive.

that's a lot of mileage. it's a nice testament to the turbo motor in keeping solid. i hope to break the 100k after im done with the payment. but at the rate im going I'll hit that mark in 10 years!

HokieAcura

Pictures up on that website now, looks to have held up very well over the course of 140k miles. Interior and exterior look just as good as our TSX with only 24k miles.

I think Acura "over built" the K23 Turbo much like they over built the accords of the early 90s. Being Acura's first turbo motor in a US vehicle I'd say they wanted to impress everyone.

I have over 160k miles on my 2007 RDX. I drive hard every day and she has been reliable aside from the fact that the turbo housing cracked on me (it could have been like that from the previous owner not cooling down the turbo properly.. who knows.)

Bought her in 2010 for $13k at over 130k miles. This seems like a good deal for one with Tech. Whoever gets it will not be disappointed.

I had a 1992 Accord sedan with 350,000 KM's (about 215,000 miles), and that was a shame to give it up after 10 years as it was flawless with no issues whatsoever. It was easily the most reliable Honda I ever had. The RDX has been great so far, but its a baby.

02SLVRSXS

No Honda engine has ever run as long as the early 90's F22 engines. They were damn near bulletproof.

By the time the F23 came out in the late 90's, quality had slipped sunstantially. The newer Honda engines don't run half as long as the old ones.

140K on a late model car is nothing. Even a Hyundai can last 140K these days without burning too much oil.

When an RDX has 200K and no problems/oil burning/turbo failure/engine knock, that would be a feat in itself.

BLEXV6

My 92 Accord was arguably the most reliable car I ever had. Had it 10 years and put 210,000 miles on it. It was a shame that I traded it in and I still got a couple grand for it.

I keep reading over and over that a turbo cool down period isn't relevant with today's designs. Is this, or is this not true? I'm at about 70K with my 2007 (one of the first 1000 made), and I NEVER give the turbo special treatment.

Mr Marco

Your dealer has a car on the lot with 140K on it? What neighborhood is your dealership in?

InfamousJamous

True, convection continues to cool down the turbo after the engine is off. I still make it good practice to cool down the turbo because I drive hard.

If anybody is looking for a high mileage RDX, be sure to check out the drive axles (esp. front right) as those tend to go bad.

DRR98

Thats ~ 28k/yr avg. Beats our ~ 20k 1st yr.

@IJ Why cool it down?

Because you can, right?

InfamousJamous

Right.

Yumcha

Probably lots of long-distance travel required. But, it is indeed lots.

BigHatch

i must be behind.. only like 44k or so on our 2007...

HokieAcura

The acura with 140k was at the acura dealer in Roanoke va, it has since sold as it's off the website. They still have an 05 TL for sale with 231k on it!!

As for cooling down the turbo it's hard to imagine a senario where someone heats it up so much then immediately shuts it off, unless your doing laps at a track. Even if you dog it on the interstate by the time you pull off an exit, turn into a gas station and find a parking spot it has probably had enough time to cool sufficiently. Same goes for coming home after work, pull into your neighborhood, basically idle/coast to your house and into your garage will be plenty of time.

That's probably why the reliability is so high on these 1st gens, its gonna be way past 150k before the turbo should have issues if properly maintained.

DRR98

We all chose our own way. There are ways to heat things up that you may not have thought of, like sustained boost. We live between the coastal range and the sierras.

Example: climbing a 10k foot mountain pass, sustained max boost? Yes. Reach the top, see a bar and pull in for a cold adult beverage. Your o/e coolant gauge shows 7 bars. Thats all you got to go on so you see no need to let it cool down before you stop the flow of coolant.

But having the data helps. And in this situation I chose to error on the side of caution. Like Mr Jagger said at Altamont...cool out people!

The best first mod is gauges.

Like I said why cool it down before you shut it down? Because I can.

InfamousJamous

The EGT gets up to 1200-1300F during normal driving. 1500-1600F at WOT. I prefer to let it cool below 900F before shutting off, which only takes about a minute.

HokieAcura

By all means if your climbing a mountain pass at 10k feet above sea level and that turbo is screaming then you immediately pull over to stop then you definately should let it idle to cool it down. I'm a huge advocate for cooling the turbos. I work in the mining industry and we train all new haul truck drivers to idle the trucks for a minimum of 5 mins for those turbos to cool regardless of what they have been doing.

If I had a turbo vehicle I'd be extremely conscious of letting it idle before I shut it down. But I'd say for 95% of the rdx owners their cooldown is the last couple minutes of the drive to their house. But again common sense should be used if you live in an area where it's 105 degrees and you drive aggresively.

@IJ I think our egt is cat temp.

Doesn't the catalyst cause an exo reaction w/fuel?

My thoughts,

cat+fuel=heat? Downstream of the turbo...
w/ less polluting more restrictive exhaust...

At idle less fuel going into cat quickly lowers cat temp as the reaction slows.

Turbo temp is the product of cyl combustion and its duration.
But the mass of turbo iron releases heat slowly. Coolant and oil both flowing at idle carry heat away best.


Need more data. I want oil, coolant and surface temp at turbo please.

We also lack fp data. I'm using DC now. Nice to have the data that Rev lacked.
Have you talked to your developer about adding fp?

InfamousJamous

HokieAcura, I'm pretty sure those who drive hard are aware that they ought to let the turbo cool down. Regular drivers need not worry as Acura designed the turbo engine to be reliable.

DRR98, I'm getting my readings from the AF sensor directly behind the turbo. No cats here. You're right, it's probably off by a bit and the turbo releases heat slowly. The developer does not know the extended PID codes for fuel pressure, but I'm sure it's there.

Anyways, I don't want to get too far off topic. Whoever bought that RDX should drop a post.

DRR98

^I see.

Sounds inconvienient every couple of years? Nice info to have though.

Opps the topic...yep thats mighty fast to 140k mi.!

I have 136k, runs as good as the day I got it!
