Anyone know about issues with 2006 X5 4.8is?

Looking at a 2006 4.8is with 50k miles.

Curious if this truck at $25k is worth it from a future maintenance standpoint.

I have heard horror stories about tranny, engine, leaking valves, ect. Any information about maintenance issues for this model is greatly appreciated!

1. google
2. bing
3 see below...the 2006 4.8is is the N62b48 engine:

Correction: 2004-06 (N62 V8 engines) have 6 spd auto trannys & 2004-06 (I6 engines) have a 6sp manual or 5spd auto tranny

I own a 05 X5 4.8iS and can speak about some issues.

Most issues posted are lack of knowledge and understanding that these are not 100,000 between plug and a few oil changes type of vehicles. They will require above level care and feeding. Most issues will announce themselves with noise, driveability, and visual signs (leaks, warning lights and codes). Fix 'em as they appear and you will have a 4x4 that runs like a 5 series, and will get you there in style.

Tires- the way you make a 5,000# vehicle handle is agressive alignment specs, and big tires. This means you will not get 50,000 miles from a set of $1800 Michelin 20 inchers.
Fuel economy- buy a 4 cyl eco box if that is an issue to you.
Parts- replace fluids FREQUENTLY and you will get a long life out of your vehicle. 5,000 or more with a Oil analysis to determine YOUR driving habits and YOUR vehicle condition. Replace anything that look worn or appears loose.
Wash and wax frequently these are not Mini vans.

keep detailed records of service work performed, parts purchased and installed, DO not keep a running tally on your Total cost of ownership (CTO) you will be happier.

Thanks for the replies! Very helpful.

Air suspension, transmission, window regulators, valve covers, lower control arm bushings, alternator/voltage regulator and plugged sunroof drains are all items that you could potentially have issues with. I love mine but they can be needy. Good luck.

Need to add the following:
Wash weekly by hand. Most people will think it is a new one. Just goes to show the lack of knowledge of the average car driver. Clean = New. As theirs is dirty which = old.

Together with my M5 and another e39 528 they are the best rides. Now if the dogs wants to ride along, or I have to drive into the city, I switch to a Minivan as it is expendable!

Great information. You X5 guys really have your act together I gotta say. I'm trolling for a used X5 now and this really helps confirm what I'm getting into. I guess I can expect many of the same things as my E46 330xi - which has 187,000 miles now.
