2003 BMW 325I Problems

What owners report

Owners of this model year most often describe rear lamp assemblies that stop working or short out, and many mention that an existing lighting recall did not cover their car. Air bag recall notices—including Takata inflator campaigns—and parts-availability delays also come up frequently, along with occasional complaints about door locks that will not release and electrical faults in the instrument cluster and window motors.

1. 1
   Exterior lighting

   Rear tail/turn lamp failure and burned connectors

   • 35 complaints (18%)
   • median 90,000 mi at 8.0 yrs old (31 state mileage)
   • 7 mention a crash, fire or injury
   • filed 2007–2019

   Complaints describe rear tail, brake and turn-signal lamps that work intermittently or quit entirely, sometimes with a bulb-out warning on the dash that stays on even after a new bulb is fitted. Several owners report that the bulb carrier or wiring connector was melted, corroded or scorched, and in some cases a small electrical fire occurred. Owners frequently say the dealer told them this was a known problem on the model, and many note their VIN was not included in recall 11V438000 for rear lamp functions. Most reports fall between roughly 44,000 and 130,000 miles, recurring over months or years rather than failing suddenly.

   What to check: With the lights on, inspect both rear lamp housings for a dark or melted connector and confirm every tail, brake and turn function works. Ask whether the rear lamp recall work was ever done and keep in mind that the connector may not have been replaced.

   2 excerpts from owner complaints in NHTSA records

   “Multiple blinker and brake lights periodically malfunction on my 2003 Bmw 325I. I understand from talking with several other Bmw owners that this is a common occurrence due to faulty design involving the grounding of the light fixtures. Furthermore, I feel this is a safety issue that Bmw should pay to have repaired.”

   NHTSA complaint #10291759, filed 2009-11, 90,000 miles

   “The warning light for my passenger side tail light has been going on and off for months as if there is a short in it. It stayed on permanently this month, showing a dimmer light than the working side tail light, so I had it checked when I had the oil changed at my Bmw mechanic. He informed me there was a recall for tail light assemblies for my vehicle and told me to call the dealer to check the VIN number. …”

   Latches, locks and linkages

   Power door locks will not release

   • 15 complaints (8%)
   • median 104,000 mi at 8.7 yrs old (15 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2009–2020

   Owners describe doors that cannot be unlocked with the remote, the center-console switch or the inside handle, sometimes leaving occupants to climb out through a window or break glass. Several mention a fault in the central locking module, with the dealer replacing an actuator; others say the dealer considered it normal. The condition comes and goes over days or weeks before returning. Reported mostly between about 38,000 and 140,000 miles, often intermittently over long periods.

   What to check: Before buying, lock and unlock all four doors several times with the fob, the interior switch and each inside handle, and ask whether the locking module or actuators have ever been replaced.

   “My 2003 Bmw 325I will not unlock. I cant get into the car. I have tried the key and the fob and the doors will not unlock. I had to break the window to get into the car only to find out the doors still will not unlock. This is a safety issue you cant unlock the doors from the inside or the outside. This is extremely concerning and a true safety issue.”

   NHTSA complaint #10439295, filed 2011-12, 114,000 miles

   “Vehicle has recurring locking issue. When inside the vehicle, door locks stop functioning. Pressing door lock button will not work. Pressing button on remote will not work. Attempting to manually open door using door handle will not work. This is a safety issue. The last incident both myself and my child were trapped inside the vehicle in the heat and had to call 911 as we did not have the key to roll down the window. The front window had to be broken and we had to be removed through a window because the door locks would not release. …”

   Electrical system

   Interior electrical faults: windows, cluster display, wiring

   • 18 complaints (9%)
   • median 77,586 mi at 8.3 yrs old (18 state mileage)
   • filed 2003–2019

   Complaints describe power windows that stop moving, sometimes with a grinding noise or needing new regulators and actuators on several doors. Others report the instrument cluster display going blank so odometer, temperature and trip readings cannot be read, and a few describe wiring that melted or a loss of engine power traced to electrical faults. Owners often say the dealer called these common failures on the model. Spread widely, from under 15,000 miles to around 175,000 miles.

   Recall 03V1600001 related service bulletin

   What to check: Operate every window from both the door switch and the master switch, check that all cluster displays read clearly, and ask whether window regulators or the cluster have been repaired.

   “The computer first failed on my 2003 Bmw 325I on june 15, 2003, (three weeks after I picked it up from the dealership, Bmw of manhattan), causing me to lose acceleration without warning. I was travelling at 60-65 miles per hour in the far left lane of the garden state parkway. …”

It was quite scaring when the vehicle was on the highway with speed at ~50-70 mpg. …”

   Air bags

   Air bag inflator recall and unavailable parts

   • 56 complaints (28%)
   • median 76,768 mi at 13.2 yrs old (12 state mileage)
   • 8 mention a crash, fire or injury
   • filed 2004–2018

   Many complaints concern Takata air bag recalls: owners describe receiving recall notices for the driver or passenger inflator but being told parts were not available, sometimes waiting months or being refused a loaner. A few describe the air bag warning lamp staying lit, and some report air bags that did not deploy in a collision. Complaints also mention the dealer declining repeat repairs because the car had already been serviced under a previous campaign. Filed mainly from about 50,000 to 175,000 miles, often years after the recall was announced.

   What to check: Ask to see documentation that both driver and passenger inflators were replaced under the Takata campaigns, and check that the air bag warning lamp goes out after start-up.

   “My wife was in a serious accident on 07/07/06. Her 2003 325I Bmw was hit on the drivers side by a SUV that jumped over the median, totaling the car. We contacted Bmw of north america and reported that none of the air-bags deployed. We are very concerned. We also to this date have not received any information from Bmw.”

   Transmission and drivetrain

   Automatic transmission clunk and delayed engagement

   • 9 complaints (5%)
   • median 13,000 mi at 1.1 yrs old (7 state mileage, few)
   • filed 2003–2017

   Complaints describe a thump or clunk from the rear when the car downshifts while braking, along with a rise in engine speed, and others report a delay of several seconds before drive engages in the morning. Some owners lost reverse gear entirely, and one was quoted a large repair bill for a transmission replacement. A few mention forums where other owners described similar behavior. Mostly reported between about 70,000 and 150,000 miles, with one delivery-mileage report of delayed engagement.

   Recall 03V124000

   What to check: Test drive from cold and note any pause when shifting into drive or reverse, then drive slowly and listen for a clunk on downshifts; ask for transmission service records.

   “I went to start my vehicle in the morning and it started and then turned back off on its own. This happened about 3 times,before it stayed on. I then drove the vehicle about 40 miles and the transmissions started to thump. The vehicle only has 100k miles. I kept up on all its maintenance. I took the vehicle to the dealership and the transmission light and check engine light both came on. I was informed it would cost 6,500 to repair my transmission.”

   NHTSA complaint #10262560, filed 2009-03, 100,000 miles

   “My 2003 325I Bmw has a defect in the transmission which caused it to, without warning, lose its ability to go into reverse. I was returning to philadelphia from nyc several days ago. I pulled over for gas. When I put the car into reverse, the transmission acted like it is in neutral. The engine would rev but was not engaged. The car has only 70k miles on it. The problem is widespread in owners of early 2000 bmws and results from a reverse drum that is poorly manufactured and not sufficiently thick around the edges. …”

Buying note. Check the rear lamp housings and every lighting function closely, and confirm in writing that the Takata air bag campaigns were completed. A pre-purchase inspection that covers the door locks, windows and transmission behavior is worthwhile on a car of this age.
