2008 BMW 3 Series Problems

What owners report

Owners of this model year most often describe electrical problems — sudden loss of power or no-start, burnt wiring and blower/connector damage, and in some cases under-dash or under-hood fires — along with stalls and loss of power from the engine, and open recall campaigns that in some complaints sat without a remedy for many months. Many reports come in the 40,000-80,000 mile range, and a recurring theme is that dealers could not duplicate the fault or told owners no codes were stored.

   Electrical system

   Sudden electrical power loss / no-start

   • 16 complaints (24%)
   • median 66,373 mi at 8.4 yrs old (12 state mileage)
   • 4 mention a crash, fire or injury
   • filed 2008–2019

   Owners describe the car losing all electrical power without warning — at stop lights, in traffic and on the freeway — and sometimes refusing to start after sitting. Several report the fault could not be reproduced on demand, and that dealers found no stored codes or could not repair it. A few describe smoke, burnt connectors and wiring, or a fire that started in the dash or under the hood area, in one case while the car was parked after being driven earlier that day. Mostly reported between roughly 40,000 and 160,000 miles, with several events occurring while parked or shortly after a drive.

   What to check: Ask for a full battery and charging-system check and whether the footwell module warranty work or battery energy diagnosis has been done. Have a shop inspect the wiring around the blower, headlights and under the dash for brittle or chafed insulation.

   “I received a recall letter telling me to stand by for another recall letter to then tell me to have the car fixed. The car blown up parked outside of my house it has not been used for 24 hours prior to the incident. I have just now recently recieved the second recall letter months later no. 17v-676”

   NHTSA complaint #11161077, filed 2018-12, 160,000 miles

   “The wires on the inside of my headlights are cracked, and have a lot of bare copper showing. The plastic sheathing (cable jacket) has become brittle from the heat, and is falling apart, exposing the conductor. This is creating the risk of an electrical fire or damage to the electrical system. The right headlight and the angel lights of my car is not working it when off while the car was in motion - all it takes is to touch a cable with your fingers and the cooper will be expose. …”

   Engine

   Engine stalls and sudden loss of power

   • 9 complaints (13%)
   • median 89,500 mi at 7.8 yrs old (8 state mileage, few)
   • filed 2009–2019

   Owners describe the engine shutting off while driving — at highway speed, in traffic and during turns — sometimes with a rough shudder or rattle beforehand and no warning. Restarting is sometimes possible right away and sometimes takes repeated attempts. Complaints also mention sluggish acceleration, hesitation, an illuminated check-engine light with reduced-power messages, and dealers reporting no codes or being unable to duplicate the problem. Spread from low mileage up past 100,000 miles; several reports occur during highway driving or acceleration.

   Recall 22V1190004 related service bulletins

   What to check: Ask whether the crankcase ventilation recall work has been completed and whether any fault codes have been stored or cleared. A pre-purchase scan for pending and stored codes, plus a test drive at highway speed, is worth doing.

   “While the car was travelling at a rate of about 45 MPH, it did something I never experienced before. It started to shake, sputter and lose power while ascending a on a paved city street that had about a 20 degree uphill grade. The vehicle behind me didn't expect my sudden speed change and nearly rear ended me.. The engine icon appeared on the dash and I sputtered all the way home.”

   NHTSA complaint #11083091, filed 2018-04, 140,000 miles

   “About a month ago, my 2008 Bmw 3 SERIES engine stalled while driving at speed 45 MPH. I received no warning before the engine stalled. It was a miracle that I was able to move over a lane and get off the road before an impact from other vehicles. This occurs every time I drive the vehicle, multiple times and at various speeds. It's very dangerous because I receive no warning before it happens. …”

   Fuel system

   High-pressure fuel pump and injector faults

   • 6 complaints (9%)
   • median 53,500 mi at 6.1 yrs old (6 state mileage, few)
   • filed 2008–2018

   Owners report long cranking, a check-engine light with reduced-power messages, rough or erratic running, and hesitation when accelerating. Some describe a strong fuel smell inside and outside the car that a mechanic traced to the fuel pump assembly. Others describe fuel injectors needing repeated replacement and the dealer declining coverage once the car passed the extended warranty mileage. Reported from under 25,000 miles through about 140,000 miles, with several cases around 50,000-80,000 miles.

   Recall 22V1190003 related service bulletins

   What to check: Ask for service records showing fuel pump and injector replacement and whether any extended warranty coverage applies. Check for a fuel smell around the rear of the car and ask about hard starting when cold.

   “Currently I have the high pressure fuel pump in my 335i (2008). I have my service engine soon engine malfunction. Reduced power light on - it just came on yesterday. Original warranty was 4 years 40,000 miles. Which according to Bmw was extended 10 years 120,000. So I am out of warranty because I already have 130k, my car was brought to Bmw several occasion, it was never brought to my attention that there may a potential problems with the high pressure fuel pump.”

   NHTSA complaint #10864596, filed 2016-05, 130,200 miles

   “I own a 2008 335i twin turbo Bmw 3 SERIES, while driving I started smelling a fresh gas smell in the back of my car inside and outside, really strong smell so much I have to keep my windows down and it gives me a headache and I feel like my car is going to catch on fire with any given spark and it could, the certified mechanic said my fuel pump assembly is faulty so I went online and there is a recall on the 2008 335i twin turbo but for some reason when I called Bmw they said my car is not on the recall list so they wont fix it! …”

   Air bags

   Takata airbag recall parts still unavailable

   • 9 complaints (13%)
   • median 67,500 mi at 7.0 yrs old (3 state mileage, few)
   • filed 2014–2018

   Owners describe receiving recall notices for the driver's front airbag inflator and then waiting many months or more than a year for parts, with dealers saying they have no remedy or no arrival date. Some report an airbag warning light on with no repair performed, and others note that a trade-in was blocked by the open recall. Reported across a wide mileage range from about 55,000 to 150,000 miles, mostly in complaints filed from 2015 onward.

   What to check: Check the VIN against open airbag recalls and confirm with the dealer whether the inflator has actually been replaced, not just scheduled.

   “Hi, I am quite frustrated with Bmw. They have experienced widespread issues with their passenger restraint systems have multiple recalls out, however my car at this time is not part of it but my passenger airbags are faulty. Bmw wants to charge me $150 diagnosis instead of ensuring the safety of my passengers. I'm writing you as this is very scary to me that Bmw is willing to risk teh safety of the my passengers and not take care of their customers.”

   NHTSA complaint #10644528, filed 2014-10, 68,000 miles

   “The contact owns a 2008 Bmw 318i. The contact stated that while driving at various speeds, the air bag warning light illuminated. The vehicle was taken to the dealer. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 55,000.”

   Electrical system

   Doors lock and will not reopen; fuel door stuck

   • 5 complaints (7%)
   • median 39,750 mi at 3.9 yrs old (4 state mileage, few)
   • filed 2010–2015

   Owners describe the electronic door locks jamming in the locked position, leaving passengers unable to open doors from inside, with the driver's door sometimes the only one that opens. Complaints also mention the key fob failing to unlock, and the fuel filler door — which locks with the doors — refusing to open at the pump. In some cases the problem appeared after a loss of power to the locks. Mostly reported between roughly 11,000 and 60,000 miles.

   Recall 09V257000

   What to check: Test every door lock and unlock cycle from both the fob and the interior handle, and open the fuel door while the car is locked and unlocked before buying.

   2 excerpts from owner complaints in NHTSA records

   “Driver exited car to pump gas. Passengers remained in vehicle. Gas door could not be opened as main door lock was engaged (though drivers door was unlocked). Key fob unlock function would not work to unlock car / gas cap. Driver pushed key fob buttons to attempt unlock, drivers door became locked during this activity. Now no doors could be unlocked. …”

   NHTSA complaint #10466934, filed 2012-07, 59,500 miles

   “2008 Bmw, electronic door locks stuck in locked position, must open driver side door with valet key. Remaining doors stuck in locked position, making it impossible for passengers to leave vehicle in an emergency situation. Related problem is that gas cap (which locks when doors are locked) will also not open.”

   NHTSA complaint #10328882, filed 2010-05, 11,000 miles

Buying note. This model year has several open or recently remedied recall campaigns, so check the VIN for outstanding recalls and confirm each repair was actually completed. A pre-purchase scan for stored fault codes, a careful look at the wiring and a highway test drive will tell you more than service records alone.
