2001 BMW X5 Problems

What owners report

Owners of this model year most often describe cooling-system and engine problems — coolant loss, fan failures, overheating — and a crankcase-vent (oil separator) freeze-up in cold weather that can push oil into the intake. Other common themes are doors and latches that freeze shut below about 20 F, window regulators that fail and leave glass stuck down, and automatic transmissions that lose reverse. Reported mileages vary widely, with many complaints filed above 80,000 miles.

1. 1
   Latches, locks and linkages

   Front doors and latches freeze shut

   • 13 complaints (8%)
   • median 66,050 mi at 4.3 yrs old (10 state mileage)
   • filed 2004–2008

   In freezing weather owners report that doors open but will not latch, or will not open at all, leaving people climbing in through another door. Some describe the door handle failing to release the latch and driving while holding the door closed. Owners report dealer replacement of latches, actuators or cables, often with the problem returning the following winter. Reported below roughly 20-25 F, across a wide mileage range including low-mileage vehicles.

   What to check: In cold weather, open and close each front door several times and check that the latch catches and the handle releases smoothly. Ask whether any latch or cable work has been done.

   “I have 2001 Bmw X5 3.0. After last week's snow storm and cold weather in boston area, my 2001 X5 doors are frozen. Actually, I opened them from outside yesterday morning (feels like door handle got frozen). But then I could not get them closed. So, I had to push down door lock (little knob) by window and pull hard to get them closed. Now, I could not open them at all. I am climbing in and out of the trunk door to get inside. Fortuately, there is no accident. …”

   NHTSA complaint #10108039, filed 2005-01, 96,000 miles

   “Front doors are freezing up in cold weather. Once the temperature rises the doors will open. Happens early in the morning/ late night when I need to leave for work. Sometimes you can force the handle to open but then the door will not close and have to drive holding the door shut. There must be a recall on this,there have been so many complaints about this issue. This has happened to me dozens of times. Went to dealer many times, replaced bowden cable/actuators. Cost me $600.00 to fix, will see if it works next winter.”

   Engine cooling

   Crankcase vent (oil separator) freeze-up in cold weather

   • 8 complaints (5%)
   • median 88,000 mi at 8.3 yrs old (7 state mileage, few)
   • owner-quoted repair $1,200 (median of 5 quotes)
   • filed 2004–2014

   In cold weather owners describe the crankcase ventilation system freezing, after which oil is drawn into the intake or forced out past seals and the dipstick. Symptoms reported include sudden power loss, heavy white smoke from the exhaust, oil spraying when the dipstick is pulled, and in some cases a seized engine. Repair estimates quoted to owners were in the range of roughly $1,000 to several thousand dollars. Reported from cold-morning starts in temperatures around 15 F and below, often between 60,000 and 140,000 miles.

   What to check: On a cold start, check for blue or white smoke and a strong fuel or oil smell; ask whether the crankcase vent valve and hoses have been replaced. Check the dipstick and oil filler cap area for oil residue.

   “Bmw - vent valve the vehicle is obviously engineered wrong and the company should be liable. The dealership told me it would cost $1,000 to replace and cleanup a frozen vent valve due to condensation from moisture. The extreme weather where I live cause the condensation to freeze causing oil to backup and blow the engine.”

   NHTSA complaint #10255314, filed 2009-01, 10,000 miles

   “I have a 2001 Bmw x-5. On a cold day in january of this year I left work and drove approximately 25 miles when my yellow check oil light came on. I could smell oil and noticed that my vehicle was smoking out the exhaust pipe. I went to the nearest service station and turned off my vehicle to check the oil. When I pulled out the dip stick, oil shot out of the hole and sprayed all over the interior of my hood, on my face and all over my clothing. …”

   Transmission and drivetrain

   Automatic transmission loses reverse

   • 9 complaints (6%)
   • median 91,265 mi at 8.5 yrs old (9 state mileage, few)
   • filed 2006–2014

   Complaints describe reverse failing without warning — the engine revs but the vehicle will not move backward, or slips when reversing up an incline. Some owners also report hesitation or a delayed response when accelerating from a stop, with a transmission fail-safe message. Dealers and independent shops typically told owners the transmission needed to be replaced or rebuilt. Reported from roughly 80,000 to 120,000 miles, sometimes shortly after purchase of a used example.

   Recall 01V196000

   What to check: Test reverse on a slight incline from cold and warm, and check for delayed engagement or slipping. Ask for transmission service records and whether the fluid has been changed.

   “I own a 2001 Bmw X5. The car is in working condition, repaired and maintained as needed. The automobile no longer goes in reverse at 91,000 miles. The transmission needs to be rebuilt. I hear this is a very common problem with Bmw's. I was told that it is the zf5hp19 or steptronic transmission. It is a failure of the d-g clutch drum. This is a huge safety hazard for the person driving the vehicle and for everyone around the vehicle.”

   NHTSA complaint #10264789, filed 2009-04, 91,265 miles

   “Tl- the contact owns a 2001 Bmw X5. The contact stated the engine will rev, but will not move when going in reverse up a hill without getting a push. The vehicle works in reverse at any other time. The contact took the vehicle to the dealer and was told there was an internal problem with the transmission and it would need to be replaced. The failure mileage was 98,000.rl”

   Visibility (wipers, defrost, mirrors)

   Window regulators fail and glass sticks down

   • 11 complaints (7%)
   • median 71,529 mi at 5.4 yrs old (10 state mileage)
   • filed 2002–2010

   Owners report windows that will not roll up or that drop into the door, usually after a clinking or grinding noise, leaving the vehicle unsecured. Complaints describe repeated regulator and motor replacement on multiple windows, including all four over a period of a few years. Some owners also report wipers becoming intermittent in rain. Reported from about 55,000 to 90,000 miles, typically over repeated occurrences.

   “Vehicle electric windows stick full open and cannot close. I bought the Bmw X5 4.4i new in 2001, I still own the vehicle, and this has happened 4 times since new (2004, 2005, 2006, 2010). Each time it renders the vehicle unusable since it cannot be secured and left unattended. The window motor regulator was replaced twice under warranty and twice I had to pay. This should not even happen once!”

   Engine cooling

   Cooling fan failure and overheating

   • 16 complaints (10%)
   • median 88,000 mi at 11.5 yrs old (7 state mileage, few)
   • 4 mention a crash, fire or injury
   • filed 2001–2018

   Owners describe the electric cooling fan stopping, which is followed by overheating, coolant loss and in some cases smoke from the engine bay or a warped or damaged engine. Complaints mention previous fan repairs, and some owners state their vehicle was not covered by the earlier fan campaigns. Others describe coolant escaping from cracked plastic cooling-system parts with little warning. Mostly reported between about 55,000 and 90,000 miles, often while driving at speed with the air conditioning on.

   Recall 02V138000Recall 01V2060001 related service bulletin

   What to check: Ask whether the cooling fan and fan control unit have been replaced and whether any fan recall work was completed. Let the car idle with the A/C on and confirm the fan runs, and check for coolant residue or a sweet smell under the hood.

   “In 2001 I had a recall for the electric cooling fan, it was supposed to have been fixed then in 2007 electric cooling fan goes out again, then in 2011 the electric cooling fan goes out again, then in 2018 the electric cooling fan goes out again overheat and blows the head gasket while driving back from las vegas in gilroy california ???”

   NHTSA complaint #11145180, filed 2018-11, 536 miles

   “Bmw X5 3.0l 2001 1) car lost power on the freeway requiring an emergency stop. Very dangerous situation but no one was injured. 2) a hole in the plastic cooling system caused the coolant to eject. The engine overheated causing total loss of engine. There were no audible or visible warnings. Apparently this vehicle does not have a coolant sensor and the engine temperature gauge can malfunction if the coolant has all leaked out. 3) entire engine replacement at 63,000 miles (out of warranty). Car has had all Bmw recommended maintenance service. …”

   NHTSA complaint #10200828, filed 2007-08, 63,000 miles

Buying note. These complaints concentrate on cooling-system and cold-weather engine faults, door latches, window regulators and transmissions, so a careful cold-start check and a reverse test are worth doing. Ask for service records covering the cooling fan, crankcase vent valve and any transmission work, and confirm whether open safety recalls have been completed.
