2006 BMW X5 Problems

What owners report

Owners of this model year most often report the passenger air bag warning light staying on or the air bag being switched off, usually traced to the front passenger seat occupancy sensor mat. A second repeated theme is heated front seats overheating, in some cases burning through the leather. Brake complaints, mainly a hard pedal and reduced power assist, form a third cluster that tends to appear at higher mileage.

   Air bags

   Passenger air bag light on / seat occupancy sensor mat

   • 77 complaints (46%)
   • median 72,000 mi at 7.7 yrs old (57 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2007–2023

   Complaints describe the passenger air bag off light or the red air bag warning light staying lit, sometimes whether or not someone is in the seat. Several owners say a dealer or independent shop traced it to the front passenger seat occupancy sensor mat and quoted a replacement. Many state that their vehicle identification number was not included in the air bag recalls and that no assistance was offered. Reported across a wide mileage range, roughly from near-new to over 170,000 miles, with many cases in the 45,000-95,000 mile range.

   Recall 13V5640004 related service bulletins

   What to check: With the ignition on and the passenger seat empty, confirm the passenger air bag off light behaves as the owner's manual describes. Ask whether the seat occupancy mat has been replaced, and whether the vehicle was covered by recall 13V564000.

   2 excerpts from owner complaints in NHTSA records

   “Passenger airbag is de-activated. Passenger seat occupancy sensor is not working. Bmw states that my production date is not inclusive of the recall# 13v564000. The recall starts mfg date 12/1/2005 forward for Bmw X5 models. Bmw customer service stated my date of mfg was 10/25/2005 and they will not cover. I need intervention with this matter. It is more than coincidence that I am having the identical issue as cars mfg less than 35 days after my mfg date. Thank you.”

   NHTSA complaint #10566319, filed 2014-02, 106,999 miles

   “The passenger side air bag off warning light came on and stays on. The dealer reset the computer. Light went off. The failure recurred again in a few months. The vehicle was taken to the dealer where it was diagnosed that the sensor needed to be replaced. I was informed that my VIN did not meet the recall for replacing the failed mat sensor although other 2006 Bmw x5s were recalled for that same failure. The warning light is presently on. I have read of many examples of the same problem. …”

   Brakes

   Hard brake pedal and reduced power assist

   • 23 complaints (14%)
   • median 107,500 mi at 8.8 yrs old (20 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2010–2022

   Complaints describe the brake pedal becoming hard and requiring heavy pressure, with the vehicle slow to stop or failing to respond as expected. Several owners link the symptom to oil leaking from the brake vacuum pump or to the brake booster, which mechanics replaced in some cases. Some reports note no warning light before the change in pedal feel. Mostly reported between about 45,000 and 160,000 miles, appearing while driving or when braking at low speed.

   What to check: Check for oil residue around the brake vacuum pump and hose area, ask about the service history for the brake booster and pump, and confirm the pedal feels firm but not stiff during a test drive.

   “The brakes failed while I was driving to work. I stepped on the brakes to stop from approximately 30mph and the vehicle did not slow down or come to a stop. I had to steer onto the median to avoid hitting the vehicle in front of me. Mechanic said the booster needs to be replaced. No warnings displayed in dashboard. Extremely dangerous and I'm lucky to have avoided a more serious accident. Someone could have been seriously hurt given the size of this vehicle.”

   NHTSA complaint #10606398, filed 2014-06, 107,000 miles

   “While sitting at a red light the brake pedal all of sudden became hard and applied a unreasonable amount of pressure against my leg. In order to make the car stop I needed to exert a tremendous amount of pressure in order to stop the car from rolling forward and hitting the car in front of me. There has been a recall for the 2007 and newer 8 cyl X5 brake boosters. Obviously this is the same problem and there should be a recall done with this car as well. Any denial on the part of Bmw that this is a product defect is a denial on their part.”

   Seats

   Heated front seats overheat or burn the seat

   • 19 complaints (11%)
   • median 84,565 mi at 8.3 yrs old (18 state mileage)
   • 12 mention a crash, fire or injury
   • filed 2008–2024

   Owners describe the driver or passenger seat heater becoming very hot, in some cases producing smoke, a burning plastic smell, and a burn hole in the leather. Several mention discomfort or a small burn on the skin. Complaints state that dealers and the manufacturer declined assistance or warranty coverage and quoted repairs around the cost of a four-figure sum. Typically noticed within minutes of switching the seat heater on, reported from very low mileage up to around 170,000 miles.

   What to check: Test the seat heaters briefly and watch for uneven hot spots, discolored leather or a burning smell, and ask whether the seat heating elements or seat modules have been replaced.

   “While driving I turned on my heated seats and about 15 minutes later my drivers side seat became very hot and started to burn me. I pulled over abruptly, jumped out of my car and noticed that my pants was discolored/burned and my seat was burned and had a burn hole (about 3.5 inches) in it., the car had a plastic type burn smell in it. I am terrified to turn on the heated seats again.”

   NHTSA complaint #10788433, filed 2015-11, 125 miles

   “The heaters in both the driver's and front passenger seats overheated to the point that it was too hot to touch and melted the leather seats. We are not sure if the heaters were even engaged at the time. We brought the car to the local Bmw service department and were denied any assistance or warranty coverage. We then called the national Bmw customer service number and were also turned down. The costs to fix this very dangerous issue would be close to the value of the vehicle. …”

Buying note. Check that the air bag warning light behaves correctly and ask whether the seat occupancy mat was ever replaced under recall 13V564000, since many owners report being excluded by build date. Also test the seat heaters and the brake pedal feel on a longer drive, as those are the other frequently reported items.
