What owners report

Owners of this model year most often write in about the front passenger seat occupancy sensor, which sets off the air bag warning lamp and deactivates the passenger air bag; many say their vehicle was not included in a related recall for the same symptom. The next most frequent reports involve heated seats overheating, wiring insulation in the headlight and tail light assemblies cracking or crumbling, and a rough 3-2-1 downshift in the automatic transmission. Reports are spread across a wide mileage range, from roughly 25,000 to over 200,000 miles.

  1. Air bags

    Passenger seat sensor sets air bag warning light

    • 44 complaints (34%)
    • median 80,000 mi at 8.0 yrs old (41 state mileage)
    • 1 mention a crash, fire or injury
    • filed 2005–2016

    The passenger air bag or restraint warning lamp stays lit, and complaints say the front passenger seat occupancy mat is cracked or faulty so the system no longer detects an occupant. Owners describe dealers diagnosing the seat mat as the cause and quoting repairs in the range of about $1,000 to $1,600. Many report that their vehicle was checked against a recall covering the same symptom and told their VIN was not included, and some describe the fault returning after an earlier replacement. Reported from about 26,000 to 180,000 miles, with many cases between roughly 50,000 and 100,000 miles.

    What to check: Turn the ignition on and confirm the passenger air bag and restraint lamps behave normally with and without someone seated. Ask whether the seat occupancy mat has been replaced and whether any recall or extended warranty applied to this VIN.

    2 excerpts from owner complaints in NHTSA records

    “I am writing to see if I can obtain some assistance with a problem I have been having with the safety equipment on my 530I, specifically the passenger side airbag. Early in 2012 I noticed that when my wife sat in the passenger seat the air bag light on the overhead light unit would occasionally come on. It would not stay on for long but would come on and off periodically. I made an appointment with Bmw on may 12 to have the issue looked into. The car had 87437 miles on it at this time. …”

    NHTSA complaint #10585575, filed 2014-04, 87,437 miles

    “My 2004 Bmw 530I has both the seatbelt and airbag light on display at all times on my dashboard. These lights on are caused by a faulty front passenger seat occupant detection mat which Bmw has an extended warranty on. After dropping my car to the Bmw dealership to get this repaired, I was informed my extended warranty expired roughly 2 months prior and I cannot have this work performed under warranty. They charged me $140 for the diagnostics and said I would have to pay $1050 out of pocket to get repaired. …”

  2. Seats

    Heated seat overheats and burns through upholstery

    • 24 complaints (19%)
    • median 101,000 mi at 7.6 yrs old (21 state mileage)
    • 17 mention a crash, fire or injury
    • filed 2008–2025

    Owners describe the driver or passenger seat heater becoming far too hot within a few minutes of being switched on, producing a burning smell and smoke and leaving a hole burned through the leather or a scorched jacket or clothing. Complaints say the dealer or manufacturer often declined to cover the repair, with some noting the seat had already been replaced under an earlier recall remedy and the symptom returned. Mostly reported between about 70,000 and 160,000 miles, usually within minutes of turning the seat heater on.

    What to check: On a car with heated seats, switch the heater on for several minutes on each seat and watch for uneven heat, discoloration of the leather, or a burning smell. Ask whether the seat elements or seat assembly have been replaced.

    2 excerpts from owner complaints in NHTSA records

    “Driver's seat on a 2004 Bmw 530I e60 almost caught on fire due to heated seats feature. I turned the head seats on and after 5 minutes I started smelling a burning smell and smoke. The fire made a small hole on the seat. I stopped then turned off the car. I was lucky and I was not driving in the highway at high speeds.”

    NHTSA complaint #10365675, filed 2010-11, 71,000 miles

    “The heated seat on my driver's side continuously got hotter and hotter, until if finally burned through the seat. My clothing was burned and so was my hand when I reached down feel the seat. I was driving at the time. This was a very dangerous situation. I my car to nob_Bmw in rockville. This is where I purchased and maintain the vehicle. The did repair it for free, but charged me a fifty dollar warranty fee.”

    NHTSA complaint #10293492, filed 2009-11, 43,610 miles
  3. Electrical system

    Cracked wiring inside headlight and tail light housings

    • 6 complaints (5%)
    • median 141,000 mi at 13.9 yrs old (6 state mileage, few)
    • filed 2014–2021

    Complaints describe the wire insulation inside the headlight housings crumbling away and leaving bare copper exposed, sometimes found while replacing a bulb, with lights becoming inoperative. A similar report describes an overheated connector at a rear tail light assembly that melted a pin and wire. Owners say dealers described the wiring as a common problem not covered by warranty and quoted replacement of the light assemblies. Reported from roughly 97,000 to 205,000 miles, often noticed during routine bulb replacement.

    What to check: Inspect the wiring visible inside the headlight and tail light housings for cracked insulation or bare wire, and check that all exterior lamps work. Ask whether either light assembly has been replaced.

    2 excerpts from owner complaints in NHTSA records

    “I had a bulb failure warning illuminate on the dash. I bought the parking light bulb, went to replace it, and found all of the wiring inside of the headlight housing crumbling to bits. There were literally bare wires crossing on top of one another, which is clearly a fire hazard. When I asked my Bmw dealer about this, they said it is a common problem, is not covered under warranty, and I have to buy new headlights. I had never heard of internal headlight wiring being considered a wear item, but Bmw says otherwise. …”

    NHTSA complaint #10639524, filed 2014-09, 97,000 miles

    “The wire harness for both headlights in this vehicle are completely frayed. Bare copper wires can be seeing and the lights are inoperative. In addition to night driveability being and issue, the potential for a short circuit and fire under the hood exists. A cursory internet research shows that this is common issue with several Bmw model years, potentially affecting thousands of drivers.”

    NHTSA complaint #11180189, filed 2019-02, 205,000 miles
  4. Steering

    Active steering malfunction warning

    Mentioned in 4 of 60 sampled complaints

    Complaints describe an active steering malfunction message appearing on the display, and in one case the steering becoming difficult to turn while driving. Owners report the dealer quoted a repair cost of several thousand dollars, and one notes the dealer could not reproduce the condition. Reported between roughly 50,000 and 190,000 miles, sometimes intermittently.

    What to check: Check for any steering or chassis warning messages on the display and confirm the steering assist feels normal at low speed and during parking maneuvers. Ask whether the active steering system has been serviced or repaired.

    2 excerpts from owner complaints in NHTSA records

    “Active steering failure: hi, I've a 2004 Bmw 530I and my active steering keeps failing and dealer is asking for $4,000 plus. I checked on internet and found this to a common issue with most of the bmws. Please investigate this as it is a serious flaw in design and consumers have to shed $4k plus and its still not a guaranteed fix.”

    NHTSA complaint #10414866, filed 2011-07, 66,200 miles

    “(note: this process does not list the 2004 Bmw 745i) I purchased my 2004 745i as a certified pre-owned vehicle from a local Bmw dealer in october 2007. Since then on 3 separate occasions the steering has totally locked. This has happened when entering or exiting a parking space and the steering wheel was turned completely to the left (counter clockwise) position. The dealer cannot duplicate the condition and there is no error code recorded in the obdi. …”

    NHTSA complaint #10214960, filed 2008-01, 50,800 miles

Buying note. On this model year, the passenger seat sensor and heated seat elements are the items owners report most, so confirm both work before buying and ask for any prior repair records. Also inspect the headlight wiring and drive the car at low speed to check for a rough downshift.
