Algunos problemas adicionales al del cambio q se reportan de ese coche :
Excessive vibration.
Lots of X5s appear vibrate a lot more than it seems should be normal for a vehicle, especially when stopped with auto transmission in drive and foot on brake.
Very noisy brakes.
Many X5s (and a few other BMWs it seems) have extremely noisy brakes that some people complain sound like old truck brakes.
Excessive wind noise.
The sunroof and the front doors seemed to be particular culprits, but also possibly the front windshield.
Excessive noise from steering column when turning/turned.
A small part may need to be replaced. See thread:
Excessive noise from misc. rattles, squeaks, and creaks.
There are a lot of complaints about rattles, squeaks, and other misc. noises in the X5.
Uneven space between rear bumper and vehicle.
Some people say that their X5 has too uneven of a space between the rear bumper and the back of the vehicle, or at least too much for their tastes given how much money they spent on the vehicle. Should be easy to check to before buying to see if it is noticable to you.
Trapped in the vehicle or doors won't open/close
There are reports of people becoming trapped in their X5s when the doors fail to unlock or fail to open.
Won't start.
Evidently, X5s occasionally do not like to start, but often will start on the second try after removing and reinserting the key.
Steering wheel won't telescope or tilt (or noisy doing so).
The steering wheel commonly breaks and will no longer move. Normally, it is both a tilt and telescoping steering wheel. It can be adjusted manually either up/down or in/out. In addition, it retracts automatically when turning the vehicle on/off to give more space for getting in/out. When it breaks, it won't move automatically or manually.
Dead battery.
Some X5s seem to suffer from inappropriate dead batteries due to fixable problems
Rear hatch issues: pops open, doesn't close right, or rattles.
The rear hatch has problems in some vehicles.
Problems with 4-way flashers (hazard lights) and/or turn signals.
Some people have experienced the 4-way flashers flashing inappropirately, during which time the turn signals do not work, and others have experienced the turn signals just not working (or not indicating their behavior on the dash).
PDC false alarms.
The park distance control (PDC) sensors that detect objects close to the bumpers using sonar sometimes give false alarms when there are no objects close by.
Key memory problem (seats, temperature controls, or mirrors act erratic).
There appears to be an intermittent but frequent problem with the key memory not remembering settings correctly and generally making the car seem haunted.
No sound from radio.
The paint on the door handles chips after several months on many vehicles.
