2006 BMW 3 Series Problems

What owners report

Owners of this 2006 BMW 3 Series report two dominant themes in the sampled complaints: the front passenger air bag warning light coming on (usually traced to the seat occupancy mat/sensor), and electric door locks that stop working so doors cannot be opened from inside or out. A smaller cluster of complaints covers a steering wheel lock warning that prevents starting, noisy or cupped run-flat tires on early-mileage cars, and occasional electrical and engine oil leak reports, mostly in the 50,000–100,000 mile range.

1. 1
   Air bags

   Passenger air bag warning light / seat occupancy sensor

   • 81 complaints (40%)
   • median 65,000 mi at 6.4 yrs old (69 state mileage)
   • 1 mention a crash, fire or injury
   • owner-quoted repair $1,095 (median of 10 quotes)
   • filed 2008–2018

   Owners describe the air bag warning light or the "passenger air bag off" indicator coming on, sometimes with a passenger seated and sometimes with the seat empty. Dealers and independent shops typically diagnose a faulty front passenger seat occupancy mat or sensor and quote a replacement, in some cases over $1,000. Many owners say the dealer or manufacturer told them their vehicle's VIN was not included in the air bag recall and that they would have to pay for the repair themselves; others report waiting for recall parts. Reported from roughly 17,000 to 130,000 miles, with many between 44,000 and 80,000 miles, and often appearing intermittently.

   Recall 08V3840003 related service bulletins

   What to check: Ask whether the passenger seat occupancy mat has been replaced and whether any recall or extended warranty applies to this specific VIN; with the ignition on, sit in the front passenger seat and confirm the air bag light and "passenger air bag off" indicator behave correctly.

   2 excerpts from owner complaints in NHTSA records

   “I have an 06 Bmw 330i with the sport seats. The passenger seat occupancy detector has been causing the srs light to come on. I did some research and found that my vehicle has the same type of seat mat that was recalled, however Bmw says that the recall is VIN specific and my car is not covered even though I have the same type of seat mat that was recalled.”

   NHTSA complaint #10378043, filed 2011-01, 74,000 miles

   “The air bag light came on and I called Bmw customer relations. They told me to take it to a Bmw dealer to have the front seat occupant protection mat replaced under an extended warranty (NHTSA campaign number 13v564000). The Bmw dealer in long beach said it isn't listed as a recall item and they want $180 just to perform a check to see if there is a problem, which is ridiculous.”

   Latches, locks and linkages

   Electric door locks fail, doors stuck locked

   • 27 complaints (13%)
   • median 68,280 mi at 5.2 yrs old (26 state mileage)
   • filed 2008–2018

   Complaints describe the key fob, central locking button and inside handles failing to unlock the doors, sometimes with a rapid clicking sound from a door. Owners report being locked inside and having to lower a window and use the physical key from outside, and say the driver's door may be the only one that opens with the key. Dealers commonly replaced door lock actuators or fuses; some owners were quoted around $1,200 for actuator replacement. Mostly between about 50,000 and 130,000 miles, and often described as recurring after an initial repair.

   What to check: Lock and unlock all doors several times with the fob and the interior button, try each inside handle with the car locked, and ask whether any door actuators or lock fuses have been replaced.

   “Yesterday, the doors on my 2006 325i wouldn't unlock with the key fob. I used the actual key to enter the car and the central locking/unlocking button does not unlock the doors. The door to the gas tank is also locked. There is no way to unlock any of the passenger doors which poses a safety hazard. In reading through online forums, this is a common problem that should be addressed by Bmw. Thank you.”

   NHTSA complaint #10504242, filed 2013-03, 100,000 miles

   “The door locks on my car failed resulting in not being able to unlock any of the doors with the key fob. I can unlock the driver side door with the valet key. None of the other doors can be unlocked and can not even be opened from the inside. If someone got locked inside the car, they could be in serious trouble. Not to mention the fact that if in an accident any passengers in my car would have been unable to get out because the door locks malfunctioned.”

   Tires

   Noisy, cupped run-flat tires at low mileage

   • 10 complaints (5%)
   • median 8,000 mi at 1.3 yrs old (7 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2006–2008

   Owners of cars with original run-flat tires report loud road noise and cupping or feathering of the tire edges starting at low mileage, with concerns about reduced traction. According to complaints, the tire maker attributed it to cupping and suggested replacing all four tires, and the dealer offered to cover only part of the cost, leaving the owner to pay the rest. Typically reported under about 17,000 miles, often near 8,000–13,000 miles.

   What to check: Inspect tire edges for cupping or feathering and listen for road noise on a test drive; ask about tire age and whether any replacement or goodwill adjustment was made.

   “I purchased a Bmw 330i in may 2006. Shortly after purchase the tires were making noise. Initially, the noise wasn't terribly objectionable, but it continued to worsen. I took the car to hendricks Bmw in charlotte, nc ,and was told that the tires were cupping or feathering. They offered a 50% discount on the purchase of 4 new tires at 11,500 miles. I called Bmw consumer affairs, and was told to contact bridgestone for a resolution of this problem. …”

   NHTSA complaint #10189947, filed 2007-05, 2,500 miles

   “Excessive tire wear on 2006 Bmw 330i. Firestone says that the cupping of the tires (starting at about 8k miles) causes less traction on the road and will get worse. The tires started to make load noise at about 8k miles and they now have 13k miles on them and the noise level is very bad. I have contacted Bmw several times and they say that they will consider replacing the tires only if I will agree to pay half of the cost(about $600 my cost for 4 tires). …”

   Electrical system

   Electrical faults: battery drain, stalling, lights

   • 10 complaints (5%)
   • median 54,500 mi at 4.9 yrs old (9 state mileage, few)
   • filed 2007–2018

   Complaints describe assorted electrical problems: a car that stalled while driving and needed a battery cable replaced, reverse lights that stopped working, windshield wipers stopping in heavy rain, and warning lights. Dealers handled these case by case, sometimes attributing them to wiring, module or battery issues. Spread from very low mileage up to about 110,000 miles, with several reports in the 50,000–80,000 mile range.

   5 related service bulletins

   What to check: Check that all lights, wipers and windows work, ask about battery and footwell module history, and confirm whether any electrical warranty extension applies to the VIN.

   “Twice in 6 weeks I have lost throttle response of the car at 70+ MPH on highways. This is a manual transmission car and I had to shift into neutral to coast to the side of the road both times avoiding catastrophic accidents. The car behaves as if it has run out of gas but there was at least 1/4 of a tank of gas. Bmw replace the fuel pump the first time in late march. It is currently in the Bmw shop now. This is an extremely dangerous situation that should be investigated.”

   NHTSA complaint #10189243, filed 2007-04, 11,070 miles

   “While driving at freeway speed during a torrential downpour, the windshield wipers ceased to operate. This caused an immediate dangerous situation, wherein visibility was almost impossible through the windshield. Not only was there a tremendous amount of water blocking my view, but the wipers themselves had stopped in a slightly vertical position, also blocking my view. This situation continued for about 15 minutes, as we carefully and cautiously attempted to get off of the freeway and away from other traffic. …”

   “Received yellow steering wheel and lock icon when trying to start the car. Attempted using different keys, but the car would not start and the steering wheel remained immobile. I exited the car and waited about 30 minutes to try again, but received yellow steering wheel with lock icon again when putting the key fob into the vehicle. When I called the dealership, I was quoted about $1200 as soon as I described the yellow steering wheel and lock, without them having seen the vehicle. …”

   NHTSA complaint #10543021, filed 2013-09, 149,000 miles

   “I brought the vehicle in to Bmw and stated that the steering wheel lock lights come on and the car will not start until a few tries. Bmw could not find the problem, since then it has progressively gotten worst and reading forums, there seen to be a legitimate problem with this issue.”

   NHTSA complaint #10503925, filed 2013-03, 9,754 miles

Buying note. On a 2006 3 Series, verify the passenger air bag system and every door lock before buying, since those are the most frequently reported problems, and ask for service records showing whether recall or warranty work was done. A pre-purchase inspection that includes the electrical system and steering lock is worth the cost.
