   “In september of 2014 my 2002 Bmw X5 front passenger side power window failed in the down position. Upon taking it into my original dealer, it was manually raised-closed and I had to return days later for installation of a new regulator at a cost of about $500. I was told this problem was unusual . …”

   “Tail lamp failure. Warning system indicated lamp failure. The failure turned out to be lamp circuit assembly, and not bulb. Repeated failures until I repaired rear lamp assembly on my own. Bmw would only suggest replacing entire lamp assembly at substantial cost. Updated 09/15/11”

   “We were backing up the car from the restaurant and driver side air bag and curtain air bag popped open but not deployed with air for no reason. Took the car to dealer they said sensor underneath the car initiated, and to repair costs will be $4,000.00. I don't have money to fix the car and they released the car to me. The bags are not deployed and afraid of deploying while driving.”

Set up an appointment to have the bag replaced at flow Bmw in winston-salem, nc on september 13, 2019, they informed the bag had already been replaced and that no repair was necessary. I checked my records on this vehicle and the air bag has never been replaced. …”

   Engine cooling

   Engine stalls and shuts off while driving

   • 15 complaints (15%)
   • median 73,709 mi at 7.0 yrs old (15 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2004–2018

   Complaints describe the engine cutting out without warning during low-speed turns, at stoplights, or at highway speed, sometimes restarting immediately and sometimes requiring a tow. Several owners say the dealer could not reproduce the problem or found no fault, while others report diagnosis of a frozen or blocked oil separator, oil entering the intake, or a failing cooling fan. Some link the stalling to sudden temperature spikes. Reported from about 25,000 to 105,000 miles, often during turns or while slowing, and several cases in cold weather.

   2 related service bulletins

   What to check: Ask whether the crankcase ventilation/oil separator and cooling fan have been serviced, and have a shop check the intake for oil residue and scan for stored fault codes.

   “Over several occasions, the car engine shut down while we are driving. We can turn it on just after when we can get the car to a safe spot. I took the car to the Bmw and they tell me nothing is wrong with the car!! This is a major safety issue and my wife had almost had a bad accident for this.”

   NHTSA complaint #10578900, filed 2014-04, 89,000 miles

   “In a 2002 Bmw X5 while making a left hand turn, the vehicle stalls. It happens numerous times per day. My research indicates this problem exists in many Bmw vehicles and it obviously presents a serious safety issue for drivers of the 2002 Bmw X5. I hope a safety recall is ordered for these vehicles immediately. If you are to google this issue with Bmw vehicles (1999-present) there is a laundry list of complaints. …”

   Engine

   Cold-weather crankcase ventilation (oil separator) failure

   • 12 complaints (12%)
   • median 84,807 mi at 8.3 yrs old (10 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2004–2015

   Complaints describe heavy grey or blue smoke from the exhaust and engine bay, oil pushed past the valve cover gasket, and oil leaks onto hot exhaust parts, usually after the vehicle sat in cold conditions. Owners say dealers diagnosed a frozen or blocked oil separator or pressure control valve and that a revised, heated part was offered as the remedy. Mostly reported from about 40,000 to 90,000 miles, and frequently during or after cold weather.

   2 related service bulletins

   What to check: Inspect for oil residue around the valve cover and intake, ask whether the heated/updated separator has been fitted, and listen for whistling or rough running at cold start.

   “I've had to replace all 4 window regulators, my rear hatch seems to open for no reason, my rear window wiper is working with the switch in the off position, LED's are going out again and now the dreaded apparent oil separator with tons of grey smoke billowing out the back of the car after being left in an airport parking lot for 4 days whilst it snowed outside. Seems I've had every typical problem other than the car catching fire for no apparent reason. …”

   “In january of 2010 during a cold weather spell, I started my car and started driving slowly. After about 5 minutes I noticed smoke coming from engine compartment and from exhaust pipes. I stopped the vehicle and had it towed to a certified mechanic. He diagnosed the issue as a failure of the separation valve that caused the increase pressure under the valve cover. Fortunately, I was able to avoid extensive damage and my bill was only around $350 (plus towing). …”

Contacted the dealer they says nothing wrong with the power steering problems, they reset the computer and said im good to go...my car is 2002 Bmw X5 3.0i.”

   NHTSA complaint #10349296, filed 2010-08, 66,500 miles

   “I was driving and I tried to turn left and it wouldn't. I tried to turn right and it unlocked it, so I was able to turn left afterwards. It did it again, this time it locked up both left and right. It eventually unlocked and I was able to bring the car home, test drove it and it seems fine again. It comes and goes. I called the Bmw dealer in vista, ca to see if there is a safety recall on it and they said that my VIN do not have a recall on steering. …”

Buying note. These reports center on stalling, cold-weather oil separator trouble, airbag warning lights and electrical faults in an older vehicle, so a pre-purchase inspection by a BMW-experienced shop and confirmation that the airbag recall was completed are worth the cost. Service records showing cooling, crankcase ventilation and window/lock repairs give a clearer picture of what has already been addressed.
