So my wife and i are looking into purchasing a used XC90. I have don't SOME research on the forums and online and found there to be many opinions and facts. Besides minor issue alike tires, brakes and such; I'm looking for more serious issues. For instance i read to stay away from all T6 engines (transmission issues) and that if i get a 2.5t to not flash the system.

So my question is what i should be looking for when purchasing a XC90 (good/bad). I should also mention we want AWD….


Thanks

Keep awawy from early V8's ( 05's and early 06's) as they have a CB issue. There is a post on here about the VIN number range for this issue.

2007+ has the AUX input standard between the cupholders in the armrest. If you can find one with the premium sound system I highly recommend it.

I disagree on NOT flashing 2.5T. I would definitely renew the transmission fluid first, do a tune up and bring it to Stage 0. The drive train is robust and will handle the extra power output fine. Why not benefit from the extra power and possibly better fuel economy?

I had read there where issue with the transmission shifting into the correct gear and such, could have easily just be one persons issues.

DO you have the 2.5t? How would you rate it with power and such..?

I would have no qualms about flashing a 2.5T. Actually, I think on the XC90, doing the flash will benefit the vehicle greatly because this same powertrain is on XC70's, S60's, S80's, V70's, etc. The reason it feels so slow in the XC90 and so quick in the S60 is because you have wildly different aerodynamics plus the drag of AWD.

As a matter of fact, I have a 03 XC70 with 154k miles that I just picked up to beat up and keep the miles off of the BMW's. I plan on doing a flash after she's buttoned up to a Stage 0.

Aerodynamics and AWD will account for minute differences in feel, the real culprit is the additional weight of the XC90.

We had 2.5T AWD for 90K miles. It was totaled in the accident, and the only reason why we did not have another one and got used V8 instead was that we could not find any used 2.5T AWD in radius of 150 miles from where we live in CA.

Great daily driver...the full torque available at 1500 RPM helps a lot...

it depends of what do you want and how much money do you want to spend. a T6 def. is not a good option due all the insane tranny failure that everybody knows. 2.5T engine is a bullet proof machine, also the parts and general maint. are really cheap. As gasco said, the torque is ready at 1500 rpms which is amazing.

I was searching a lot on different engines when i got mine, but the 5 cylinder engines are master piece, thats why i went with the 2.5T and im more than happy with it.

I purchased an '04 Nautic Blue Metallic T6 with 115k miles. Appearance and performance all around are that of a vehicle with less than half the miles. The transmission had already been replaced at 100k miles with a 100k, 36 month warranty. So I have 85k miles or about 25 months left on the warranty. Interior is immaculate (black graphite), and the body in my opinion is in good condition compared to an average 2008. I was already in the market for one and had been looking for about 2 months for the right color combo, drivetrain, condition, mileage and price. I knew exactly what I wanted and found it on a Ford dealership used lot. They had the vehicle listed for 11,999 and I ended up getting it for 10,200. I am a performance technician and EFI tuning specialist. I took the vehicle to my facility and put it on the lift and did probably a 100 point inspection, especially concentrating on suspension, bushings, steering components, wheel bearings, and brake calipers. I am throroughly impressed with the condition of the vehicle that I got for the price and is perfect for my family (wife and 2 children, 9 years and 7 months), as well as the ability to throw our golden retreiver in the back with the 3rd row seating down. I also leaves the opportunity for performance modifications with good power potential (come on, I operate an AWD dyno and modify and tune forced induction vehicles every day), of course I'm gonna modify the car :) Sorry for the extremely long rant, but to sum it up, these are great used vehicles at great prices and PLENTY of near showroom condition vehicles available on the market. Just figure out exactly what you want and have the vehicle thoroughly inspected by a trusted and comptetent technician. Just like any used car, some are gem's, and some are lemons.

Kevin, you may want to search the GM boards on how to mod the tranny to make it more reliable, before doing too much to get more power from the engine. If you are unaware there are some claims that coolant was entering the transmission fluid, through he tranny cooler in the radiator which caused the problems with the transmission. While it is possible that such a failure caused some of the issues, I doubt it caused all the issues.

I'll definitely look in to that, thanks for the heads up. As far as I know, the tranny fluid hasn't been changed since the tranny was replaced 15k miles ago. I plan to change and inspect it very soon just for a piece of mind and to get any insight if there may be something going on.

You might want to use quaility trans fluid also. Have been using Redline oil D4 ATF when I flush and refill.
My 04 T6 has 112,000 trouble free transmission miles so far.
Filter and flush on T6 trans, simple do it your self job in few hours first time.

I have owned 3 turbocharged 5-cylinder volvos and one 3.2 normally aspirated, along with a host of older models that don't apply to this conversation. The 2.5 is a nice package, so is the more curent 3.2.

The main difference is the 2.5 provides all it has in the way of torque right off the start with a 5-speed, and the 3.2 maxes out its torque considerably higher in the rpm band with a 6-speed. Despite the manner in which the motors and transmissions both run, they are about equal on performance with the following exception: once the 3.2 reaches its max torque level, and the 2.5 is spinning at the same speed, side by side with foot to the floor, the car with the greater horspower wins (and that is the 3.2).

If you are unable to find a nice clean 2.5 AWD, I would not hesitate to jump into a nice clean 3.2 as we did when we traded our 2004 2.5 on a 2007 3.2 with 34,000 miles. We love the 3.2 as much (maybe more) than the 2.5. The 2.5 drove nicely but the sound isolation between cab and engine compartment was not good, and the 2.5 needs a balance shaft to smooth things out and at higher rpm you can notice the harshness when you really wring one out. The 3.2 is turbine smooth at all rpm by comparison because it is internally balanced with six cylinders. One last thing, I would never buy a car with a K&N air filter.

Regards,

P

My order of preference, having owned all three.

1.) V8
2.) 2.5T
3.) 3.2

Thanks for all the responses. I couldn't find a XC90 that fit my needs (price/millage) and didn't want to deal with not having a warranty. I decided to go with a VW Tiguan SEL, which i am extremely impressed with.

Again thanks for all your advice and suggestions.
