2009 BMW 328I Problems

What owners report

Owners of the 2009 BMW 328i most often describe engine stalling or shutting off while driving, which several complaints connect to the PCV valve heater recall, along with air bag warning lights tied to the passenger seat sensor. Electrical faults (battery cable corrosion, blower wiring, a no-start condition) and fuel gauge/fuel pump problems are the next most frequent themes, and most of these reports arrive between roughly 60,000 and 120,000 miles.

   Engine shuts off while driving / PCV heater recall

   • 42 complaints (22%)
   • median 107,000 mi at 12.1 yrs old (17 state mileage)
   • 5 mention a crash, fire or injury
   • filed 2011–2024

   Complaints describe the engine cutting out at speed, a check-engine light, and in some cases smoke or a burning smell from under the hood. Many owners mention notification of the PCV valve heater recall and say parts were unavailable at the time, or that a repair was done and the trouble returned. A few reports describe a squealing or whistling noise before the stall. Spread from about 50,000 to over 130,000 miles, with many reports after the recall notice in 2022 when parts were still short.

   Recall 17V683000

   What to check: Ask whether the PCV valve heater recall was completed and keep the paperwork; check for a burning smell, smoke from the vents, or oil residue around the valve cover.

   “I began experiencing trouble with my 2009 Bmw 328I sedan as early as january 2017. The air conditioner would sometimes go on and at other times it wouldn't go off .I was experiencing the same problems with the heater. Shortly after my car began to overheat and stall out.it would hold back until I was in 4th gear, if I even made it that far before dying out. It began to sound like a old vw. L reached out to my local Bmw service dept. For repairs. I was told that the problems my vehicle was having,.was not under recall by Bmw at that time. …”

   Air bags

   Cabin air bag light on / passenger air bag off (seat sensor)

   • 29 complaints (15%)
   • median 81,000 mi at 8.0 yrs old (20 state mileage)
   • 3 mention a crash, fire or injury
   • filed 2013–2025

   Owners describe the air bag warning light staying lit or the passenger air bag light showing that the seat is unoccupied even with a person sitting there. The rear-seat or passenger seat occupancy mat sensor is usually what the dealer identifies, and owners say they were quoted repair costs of roughly $1,100 to $1,500 or more. Several complaints note that earlier model years were recalled for the same sensor but that this year was not covered. Reported mostly between about 55,000 and 80,000 miles, often appearing one morning at start-up and then staying on.

   4 related service bulletins

   What to check: Turn the key and confirm the air bag light goes out after the self-check; with someone sitting in the passenger seat, the 'passenger air bag off' indicator should not be lit. Ask whether the seat occupancy mat has been replaced.

   “My passenger airbag off and seatbelt warning lights are constantly lit up on both the dash and the airbag light on the roof. This began a couple months ago one day when I started the car and has been constant since. I brought my car in to be diagnosed and was told that I have a faulty passenger occupancy sensor, and was quoted $1,100 to repair. It has come to my attention that there was a recall on this sensor in many 2004-2007 Bmw vehicles including the 328I, just not my year. …”

   NHTSA complaint #11013940, filed 2017-08, 55,000 miles

   “It started happening here and there, while no one is in the passenger seat, it is saying seat belts need to be on and an airbag light, after a little while of driving the airbag light sometimes goes off but seat belt light will stay on. Even when someone is in the seat with their seat belt on - both of those lights are on seat belt and airbag. I'm scared if I get in an accident the airbags wont deploy. I'm also seeing I'm not the only Bmw with this issue. Why is there no recall when this can cost someone their life. …”

   Electrical system

   Electrical faults: no-start, battery cable corrosion

   • 35 complaints (18%)
   • median 99,000 mi at 9.0 yrs old (15 state mileage)
   • 4 mention a crash, fire or injury
   • filed 2013–2026

   Owners report the car failing to start or shutting down completely with multiple warning lights, sometimes needing a jump or tow. Some describe corroded battery cable connections in the rear compartment and water getting into the trunk area, and others mention charging fault or battery diagnosis issues. Complaints about the blower motor wiring recall also appear, usually about parts not being available. Mostly reported between about 80,000 and 140,000 miles.

   Recall 19V472000Recall 17V6760003 related service bulletins

   What to check: Inspect the battery and cable ends in the trunk for corrosion or moisture, and ask whether the battery cable and blower wiring recalls were performed.

   “While making a left turn, to proceed up the street leaving work, several malfunction lights displayed on the dash and than my car shuts down completely; no inside nor outside lights (it was dark outside), no dings or anything. I thought maybe I needed a jump. Called a co-worker before he left work, whom also has a Bmw. He said it was not a jump I needed and proceeded to go in the trunk to locate my battery. …”

   NHTSA complaint #10820487, filed 2016-01, 139,000 miles

   “The battery connections in the rear compartment have completely corroded. My mechanic has told me this is a common issue with many Bmw series not just the 3 series. Water seepage appears to be a specific problem with failures to rubber gaskets in the trunk/rear lights in this convertible. The repair is $2,000.00 as the entire cable system must be replaced to the engine an 11 hour job. This is a well known issue but not acceptable from a car that has been garaged its entire life. …”

   Fuel system

   Fuel gauge/fuel pump stalling and no-restart

   Mentioned in 8 of 60 sampled complaints

   Owners describe the engine dying at highway speed and refusing to restart until the car sits for a while, with fuel pump or fuel module fault codes stored. Some say the fuel pump or module was replaced and the problem came back, and others report difficulty fueling the tank. Complaints frequently mention a check-engine light with the stall. Reported roughly between 50,000 and 115,000 miles.

   1 related service bulletin

   What to check: Ask for service records on fuel pump and fuel module replacement, and note whether the car has ever stalled or needed a long crank before starting.

   “Airflow meter/sensor - car sputters and struggles with air intake causing the car to stall. I was driving 45 MPH and my car turned off. This happened back in 12/2017 - I took the car into the shop to fix the problem ($1300+) and the same issues are happening again. July 2018 driving 33 MPH and my car stalled out.”

   “I was driving south on rte 495 in ma in the left lane and had just passed the exit ramp to rte 3 when the car seized and dramatically slowed down, I was going 70-75 MPH with other cars behind and next to me going the same speed. It's only due to the alertness of the driver behind me that both of us are not dead. He swerved into the middle lane and went by me. After that I crossed three lines of traffic going at 10-20 MPH on a major highway. …”

   Engine cooling

   Overheating and cooling system leaks

   Mentioned in 4 of 60 sampled complaints

Owners also mention power reduction messages and VANOS-related faults on some engines. Generally reported from about 60,000 miles upward, with several past 100,000 miles.

   3 related service bulletins

An independent mechanic came out to inspect the vehicle and was able to start the engine. The mechanic located a leak at the top of the radiator hose. The mechanic replaced the radiator hose, but the failure recurred on july 20, 2019 while driving 60 MPH. …”

   “The contact owns a 2009 BMW 328i. The contact stated that while driving at an undisclosed speed, the engine overheating warning light illuminated. The vehicle was driven to the intended destination, which was nearby. The contact stated that the temperature gauge was displayed at 240.

Buying note. Look for a car with recall paperwork showing the PCV heater and battery cable repairs were completed, and budget for wear items like the cooling system and possibly the seat occupancy sensor. A pre-purchase scan of stored fault codes and a check of the air bag and warning lights at start-up will catch most of what owners report.
