What owners report

Owners of the 2007 525i most often report the passenger seat occupancy mat failing, which sets off restraint-system warnings and, in many cases, leaves the passenger air bag inactive until the mat is replaced. Steering wheel lock (ELV) warnings that can prevent starting, water getting into the electronics under the spare tire, and crumbling headlight wiring are the next most frequent themes. Reports cluster from roughly 50,000 to 130,000 miles and many vehicles were past warranty when the symptoms appeared.

  1. Air bags

    Passenger seat mat sensor / restraint system warning

    • 26 complaints (36%)
    • median 89,500 mi at 6.8 yrs old (22 state mileage)
    • 1 mention a crash, fire or injury
    • filed 2008–2023

    Owners describe a "passenger restraint system" or air bag warning appearing on the message display, sometimes only when someone sits in the front passenger seat and sometimes intermittently. Dealers and independent mechanics typically diagnose a faulty front passenger seat occupancy mat sensor and quote roughly $1,200 to $2,000 to replace it, and several owners say the work was not covered. Some report the warning returning after a replacement, and several say their VIN was not included in the occupant classification sensor recall. Mostly reported between about 50,000 and 135,000 miles, often noticed during ordinary driving or when a passenger first gets in.

    Recall 13V564000

    What to check: With the ignition on, confirm no restraint or air bag warning is displayed, and have a passenger sit in the front seat to see whether the "passenger air bag off" indicator changes state. Ask whether the seat mat sensor has been replaced and whether the occupant classification recall was performed for this VIN.

    2 excerpts from owner complaints in NHTSA records

    “Passenger restraint failure warning came up on my 2007 525I. This has been a problem on previous models but after taking my vehicle into the dealership they informed me it would not be covered and would cost me roughly $2000 to repair. This is a severe safety issue as nobody can ride in the passenger seat. This should be covered with the other vehicles.”

    NHTSA complaint #10605797, filed 2014-06, 94,000 miles

    “I want to express my disappointment at the lack of urgency shown by Bmw in addressing my concerns with regards to the recall issued due to malfunctioning of the front air bag seat occupancy sensor mat. My car had this problem in mid dec 2013, just before the recall notice was issued. Since this malfunction was safety related, I rushed to get the car repaired immediately. …”

  2. Steering

    Steering wheel lock (ELV) warning and no-start

    • 12 complaints (17%)
    • median 62,500 mi at 6.9 yrs old (8 state mileage, few)
    • filed 2010–2017

    Owners describe a yellow or red steering-wheel-with-padlock warning on the instrument cluster and a message on the screen, sometimes with the car refusing to start on later attempts. The car often drives and steers normally while the light is on. According to complaints, dealers usually recommend replacing the steering column or the ELV lock assembly, with quotes in the $1,000 to $1,500 range, and some owners report repeated module reprogramming or battery and sensor swaps without a lasting fix. Reported from about 34,000 to 90,000 miles, frequently at startup or after the car has been parked.

    1 related service bulletin

    What to check: Start the car several times from cold and watch for any steering lock warning on the cluster or screen. Ask whether the ELV lock, steering column, or related modules have been replaced, and get any related invoices.

    2 excerpts from owner complaints in NHTSA records

    “I got in my car to go home from work, and a red warning light came on saying steering wheel lock malfunction I have read that this is a problem with most Bmw 3 series and some 5. I had the battery changed one year ago for $800, so it can't be the battery. I believe this is an issue Bmw knows about, but will not issue the proper recall.”

    NHTSA complaint #10644463, filed 2014-10, 89,950 miles

    “At 51000 miles a red light with a steering wheel and a padlock appeared on the dash. The car starts and steers ok with the red steering lock light on. There are no mechanical issues with the car but the light and a message stating go to a safe place before turning the car off. I brought it to the dealer and they tell me the whole steering column has to be replaced to get rid of the red light and the message on the navigation screen. …”

    NHTSA complaint #10939946, filed 2017-01, 51,000 miles
  3. Electrical system

    Brittle headlight wiring and lamp failures

    • 5 complaints (7%)
    • median 110,000 mi at 9.8 yrs old (3 state mileage, few)
    • filed 2015–2021

    Owners describe headlights and other bulbs failing repeatedly, and on inspection the insulation inside the headlight housing is found cracked or flaking off, leaving bare wires that short. Complaints mention intermittent high and low beams, parking lights dropping out, and daytime running lights failing, with the only offered fix being a complete headlight assembly at around $1,250 to $1,500 per side. Mostly reported between roughly 70,000 and 140,000 miles, often noticed when a bulb is replaced or a light fails at night.

    What to check: Check that every exterior lamp works, including high beams and parking lights, and look inside a headlight housing for cracked or exposed wiring if a bulb has failed. Ask whether either headlight assembly has been replaced.

    2 excerpts from owner complaints in NHTSA records

    “When I realized a lightbulb in my headlights went out I bought the bulb online ready to replace it. I realized when replacing that the wires connecting to the headlights are completely flaked off. So I wanted money on a new bulb because it won't light up regardless. Now this not only causes the bulb to not work but it messes with the lights in the whole side of the headlight. My entire left headlight tweaks. Sometimes jus one parking light is out, then it's the high beam that doesn't work, then it's the low beam. …”

    NHTSA complaint #10882844, filed 2016-07, 140,000 miles

    “Went to replace my front headlamp bulbs after headlamp failure while operating my vehicle at night, on a winding road, in rural texas. Mechanic pulled the sealed housing, and discovered that the majority of the wires in the headlamp assembly had faulty insulation. The insulation had flaked off to the point that many of the wires were exposed, causing a short circuit, and failure of the headlamp. Researched the issue on many forums, and it is a common occurrrence. Replacement costs of each headlamp assembly is approx $1500. …”

    NHTSA complaint #10889173, filed 2016-07, 110,000 miles
  4. Electrical system

    Water in trunk electronics / electrical faults

    • 5 complaints (7%)
    • median 50,000 mi at 5.0 yrs old (5 state mileage, few)
    • 1 mention a crash, fire or injury
    • filed 2008–2016

    Complaints describe water collecting in the spare tire well, where a main module and wiring sit, after a spill, a leaking trunk seal, or a broken wire in the trunk harness boot. The result is described as short circuits, modules restarting, warning lights, and in some cases a trunk that will not open or close electrically. Owners report difficulty getting a clear diagnosis, and a service bulletin notes that water ingress into the luggage compartment can cause electrical faults in several modules. Reported from very low mileage on cars where liquid got into the trunk up to about 105,000 miles where seals had aged.

    1 related service bulletin

    What to check: Lift the trunk floor and check the spare tire well and the module area for dampness, corrosion, or a musty smell, and inspect the trunk lid harness boot for cracked wire insulation. Ask whether the trunk has ever leaked or held water.

    2 excerpts from owner complaints in NHTSA records

    “I was driving through a canyon area, and water spilled out of my ice chest into the trunk bay, where the spare tire is stored. Apparently the entire cars computer and wiring is underneath the spare tire. The water fried my tire pressure monitor module, which caused the computer to restart. When it restarted, the car showed a car computer failure. The car has safety features such as stability control, and many other safety modules connected to the computer. …”

    NHTSA complaint #10421500, filed 2011-08, 38,000 miles

    “Trunk locking failure. Unable to open trunk with remote control or switch inside the car. I was only able to open the trunk with the key over-ride from the trunk. Bmw USA customer service did not provide any assistance to open the trunk. I had to read the manual to be able to over-ride the electrical systems. Once I opened the trunk the trunk would not close. After extensive internet research and electrical trouble-shooting, I found broken brown electrical wire in the trunk harness boot above the battery compartment. …”

    NHTSA complaint #10425331, filed 2011-09, 50,000 miles

Buying note. On this model year, pay most attention to the passenger restraint warning and the steering lock warning during a test drive, since both are common and can be expensive to put right. Ask for service records covering the occupant sensor recall, the ELV or steering column, and check the trunk floor for water before buying.

Example complaints

Air bags: “Passenger side air bag warning. Took vehicle to dealer here in florida - we are here for the winter. Dealer bramen in west palm beach quoted us $1700 to repair. We declined as we thought the cost was exorbitant. The dealer rep said it was a safety problem and needed repair. I have looked on the internet and see prior model years have been recalled for what appears to be a similar problem.”

NHTSA complaint #10375896, filed 2011-01, 62,000 miles

Electrical system: “Bought the car in aug started using the seat warmer about december of 2014. Here and there upon using I'd smell something burning so I would turn it off! But not all the time when using the warmer did I smell burning! Late march my husband noticed a burn hole on my driers seat, I instantly remembered the burning smell when sometimes using the seat heater! I'm lucky I was not burned but my driver seat is ruined and I'm now afraid to use the heaters, ever!”

NHTSA complaint #10703920, filed 2015-04, 75,000 miles

Steering: “I have a Bmw 525I 2007, which was a certified pre-owned vehicle bought from east bay Bmw. Around 71,000 miles, the 'steering wheel lock malfunction' light came on (red color). The car is drivable, and works fine, however, the light is still on with a warning that the engine may not start. I asked Bmw of mountain view for a quote. They say that the elv lock (steering wheel lock) and screws need to be replaced for $1521.49!! That's insane. I see many many other Bmw owners complaint about the same issue. This should be a recall. …”

NHTSA complaint #10716489, filed 2015-05, 71,000 miles

Engine: “The NHTSA database is showing a recall for my car has not been completed. However I am currently in south korea with my car and the dealership here is telling me that the recall has been completed. This is a conflict. I can not ship my car back to the us without this recall being cleared. Can someone provide me documentation showing that the recall has been satisfied.”
