I'm looking at a 2009 RL and I need to know if there are any issues I should know about.My main concerns would be tranny and mpg on the AWD cars..Any help would be appreciated..

 

There are no known common issues documented here. However, we have probably fewer than 10 2009 owners. The MPGs suck. That's the beast of a 300hp, 2ton, AWD, sedan. You have to pay to play. You can expect 17/22/26 city/mixed/hwy from a 2009 if you aren't flogging VTEC everyday.

Tranny is solid on all years.

 

Tranny is solid only if you use only HONDA Genuine oil.

How can you get 17/22/26? i have never had these on my '06 i get mostly at best conditions, city 11-14 / mixed- 17 / and 21 on hwy. and all this is i keep my foot of the pledal most of the time... Anyway i on LPG so it is cheaper a bit,

 

17/22/26 is about right for me

 

I don't know what LPG is, but I hope it is not low-octane fuel. The RL is tuned for 91 octane. Using any less will introduce the potential for engine ping. The car has sensors which will detect ping and retard timing to avoid it. This will introduce a loss of power and will result in worse fuel economy. Please use 91+ octane in your RL.

Air up you tires. The OEM recommendation of 30/32 PSI is too low. 34-36 all around is the perfect compromise between comfort and mileage. If you are driving 90%+ highway, bump it up to 40-42 psi.

If fuel economy is a concern, don't buy high performance tires. Better traction = higher rolling resistance = more power to move the car. Obviously, the catch is a worse cornering and longer breaking distances. Again, there are compromises like a performance oriented all-season. BS or DWS come to mind.

Clean you air filter and change your oil regularly.

For daily driving, I was getting 21-22 MPG on 50/50 city/hwy driving for 6 months. I moved and that changed to 19-20 on 70/30 driving for a year (driving through suburbs ). My job then moved downtown, and I was getting 18-19 on 80/20 driving with lots more lights and more stop and go traffic. I get 15-16 mpg in a 4.7L V8, 5000 lb truck driving into the city everyday. With the RL on 100% highway trips, I saw as high as 28 mpg averaging 80 mph.

It is possible your car needs a tune and some new spark plugs. Something is wrong if you can't get over 21.

 

I get 17mpg if i do the trip 70% hwy and the rest in the city.

the best i get from the 55 liter LPG tank is around 211-225 miles.
In the city only, from 55 liter LPG tank i get ~160 miles.

Thats the best i can get from LPG, considering that it LPG usage is around 8-11% more that petrol.

 

Appreciate yours 2cents, it will help other for as long as this forum will be alive
Here's what I do, and do to the car regulary.
Check tire pressure-every week. Replace air filter every 5000km. Replace oil at around 8000- 9000km, spark plugs every 25-30k km. gearbox and diff oil every 3rd oil change. I even replace the pollen filter with every oil change. And also I adjust the valves every 3rd oil change.

I know everyone tells me that I take care too much for the car. But so far It didn't let me down. And on the clock it has about 173k miles. And still if I reset my trip meter just before entering hwy I het 22.5 on cruise control @73mph with two speed places where I have to take the speed down to 30mph and then back up to 73mph. And within 1000 miles average is 15mpg. This is the usual value I get on the trip computer.

LPG stand for liquid petroleum gas http://en.wikipedia.org/wiki/Autogas is more info if you are interested.

 

Thanks. I didn't realize you were in Lithuania. I also didn't realize the Legend could run on LPG (to be honest, I didn't even know what LPG was). Are there any special modifications to the fuel system that need to be made to run LPG? Is it possible that LPG is the reason for your ~25% decrease in fuel economy? We have ethanol added to some of our gasoline in the states, and it causes a decrease in efficiency.

 

Here we have also i think 10% of ethanol in petrol, and seems that they are adding another 5 to the RON98, so in total of 15%.

LPG - needs, separate fuel tank, separate injectors, pressure inverter, ECU that controls it and so on., its totally a separate system. I start my car on petrol , when it reaches ~80F switches to the LPG.

Maybe its the LPG, but the car ECU doesn't know what fuel i burn. i should count as i am using petrol, and the difference i should wee when the math is done by myself on the paper. In theory it should use around 10% more than with petrol but considering the price, its cheaper anyway.

By the way, i own not a Legend... Its, imported from US.

Here it is, my "snowywhite" or others call it "swan". Only at the moment the left front light is broken, by the way i am looking to buy one left light.

 

I wonder if that could be part of the problem with the vibration. That mileage is horrible. I can squeeze out about 400 miles to a tank. I drive mostly highway. My mpg gauge says avg is about 23.

On a side note I had hail damage to my car and they gave me a Nissan Rouge for a rental, now that car sucks!

 

oops, my bad on the vibration that was another thread.

 

Mate most of the car sucks after you drive the RL for a while...

 

I'm totally lost now.

 

Love it.. and it's sooo true. Drove my brother's Audi A4the other day. What a piece of crap, relatively speaking of course.

 

I drove a 2005 Honda Accord 4cyl 4 door sedan with 80,000 miles on it the other day and after returning to my RL the difference was nothing short of amazing.

 

Check the truck regularly, I've found water in there from a leaking tail light gasket. Only problem I've had with mine. Good indication is moisture in the tail light itself. Cheap fix BTW, $25. Mine was under warranty though.

 

Untrue. See the current thread, "Trans fluid change procedure."

 

Well i have learned my lesson, will never be filling anything except DW1. You can see my last post on the same tread.
Honda fluid is really different no matter what the packaging form non genuine fluid maker, whether its Amsoil on anything else...

 

Since it is AWD - it does need fluids for Tranny/Transfer and Diff. Keep those fluids maintain and it is a solid reliable power train.

Regarding MPG - if you are in a city similar San Francisco like I am with stop signs/lights on every street, expect MPG to take a big hit ~14 MPG (90% city driving) . On Highways I get about 26 MPG (~70 to 80 MPH)... Those stop and go city driving really kills the RL MPG. I think electric/hybrid car is the way to go for that type of driving condition.

 

Streuth mate! There must be very few Acura RLs in Lithuania.
