2010 BMW 528I Problems

What owners report

Owners of the 2010 BMW 528i most often report engine and engine-cooling problems, especially at higher mileages: PCV valve heater failures associated with recalls, VANOS/camshaft bolt faults that cause stalling or loss of power, and oil leaks. Electrical faults, unexpected shifts into neutral, passenger restraint warnings, and fuel odors are also recurring themes in the sampled complaints.

   • median 122,000 mi at 11.4 yrs old (12 state mileage)
   • 4 mention a crash, fire or injury
   • filed 2013–2025

   Owners describe a burning plastic smell, smoke from under the hood, and in some cases smoke entering the cabin through the vents, often noticed after starting the engine or while driving. Several complaints reference the PCV valve heater recall and say the dealer had no parts or no remedy available, sometimes for many months. Some owners report the engine oil leaking in connection with these symptoms. Reported from roughly 90,000 to 180,000 miles, in complaints filed from 2017 onward.

   Recall 17V683000

   What to check: Ask whether the PCV valve heater recall was completed and get written confirmation. Before buying, check for a burning or oily smell after a cold start and look for oil residue around the valve cover.

   “Recall campaign no.: 17v683: pcv valve heater on january 22, 2018, while traveling westbound on the 10 freeway, my vehicle began to smell of burning plastic.

   Fuel system

   Fuel odor and fuel leaks near the tank

   • 8 complaints (12%)
   • median 99,500 mi at 6.5 yrs old (6 state mileage, few)
   • filed 2013–2024

   Owners describe a strong gasoline smell inside the cabin, in the trunk, and around the rear wheels, especially after parking. Mechanics traced some cases to a cracked plastic fitting or tube on top of the in-tank fuel pump assembly, allowing fuel to pool and vapor to build up. Some owners say the dealer found no leak, while others had the sending unit replaced. Reported from about 60,000 to 170,000 miles, frequently after driving and then parking.

   1 related service bulletin

   What to check: After a test drive, park and smell around the rear wheels and inside the cabin for fuel vapor. Ask whether the fuel pump assembly, sending unit, or tank seal has been replaced.

   NHTSA complaint #10557062, filed 2013-12, 99,000 miles

   “While having my oil changed, I told the mechanic that I smelled a little bit of gasoline when driving and to check it out. I was shown that under the back seat, behind the driver side there is a sending unit and a fuel line that transfers gas from one tank to another. This plastic component has a tip where the fuel line connects. This tip cracked and broke (no idea why), leaking and pooling gasoline inside the car, directly underneath the passenger seat and filling the car with highly combustible fumes. …”

   Transmission and drivetrain

   Unexpected shifts into or stuck in neutral

   • 6 complaints (9%)
   • median 71,000 mi at 9.0 yrs old (3 state mileage, few)
   • filed 2013–2024

   Owners describe the car abruptly dropping out of gear into neutral while accelerating or at low speed, sometimes with a sudden rise in engine speed and a transmission warning. Many say restarting the car temporarily restores normal operation, and several report dealers stating there was no fix available. A few describe the reverse, with the car lurching or surging forward at a stop. Reported from roughly 50,000 to 170,000 miles, most often during normal driving at low to moderate speed.

   1 related service bulletin

   What to check: Test drive at low and highway speeds and watch for any delay, flare, or drop out of gear. Scan for stored transmission codes and ask whether the transmission or mechatronic unit has been serviced.

   “While driving, all of a sudden, it comes to neutral and engine RPM goes to around 4000 and transmission malfunctioning sign comes. I have to pullover and restart the engine. After that it runs smooth. It happens once a while. In last two months it happened six times. Two times I was on the highway and hardly survived from the accidents. It is a serious safety concern.”

   NHTSA complaint #10780675, filed 2015-10

   “While accelerating the car jumps into neutral randomly. Whether from a slow start or accelerating on a highway. It has happened dozens of times and the dealer says there is no fix.”

   Passenger restraint system warning

   Mentioned in 5 of 58 sampled complaints

   Complaints describe a persistent passenger restraint system or airbag warning on the display, with owners reporting the passenger seat occupancy sensor as the likely cause. Owners say dealers told them no recall or coverage applied, and some note similar coverage for earlier model years. A few also link it to other electrical functions such as phone or audio controls not working. Reported from about 50,000 to 100,000 miles, often appearing while driving or at startup.

   What to check: Turn the key on and confirm the passenger restraint warning clears after the bulb check. Ask whether the seat occupancy sensor or mat has been replaced and whether any goodwill coverage was offered.

I called the dealer for my 2010 528I and they are saying there is no recall; however I see thousands of users across the country are complaining about the same issue.”

   NHTSA complaint #11181409, filed 2019-02

Buying note. This model year shows recurring engine and cooling-related faults along with a known recall history, so a thorough pre-purchase inspection and a check of recall completion are worthwhile. Given the higher mileages involved, expect oil leak and cooling system attention and ask for service records covering the engine and transmission.
