   Sudden stalling or loss of power while driving

   • 12 complaints (23%)
   • median 90,000 mi at 6.7 yrs old (9 state mileage, few)
   • filed 2014–2026

   Owners describe the engine cutting out or the car losing power while driving, sometimes at highway speed, and some cars are then stopped on the roadside. Some complaints link the stall to a failed fuel pump or low fuel pressure, and a drivetrain or power train warning appears in some cases. In some reports the engine would not restart after stopping, and the car had to be towed. A complaint says the dealer repaired the problem, but it returned a few months later. Where mileage is listed, most reports are between 60,000 and 113,000 miles, though a report lists about 3,800 miles.

   Recall 15V189000

   What to check: Ask whether the fuel pump recall (15V189000) has been completed, and have stored fault codes for fuel pressure, misfires, and power train faults read before buying. Ask for a road test at highway speed that includes a restart after the engine has warmed up.

   “While the car was in motion, the fuel pump failed, the vehicle stalled without warning, increasing the risk of a crash. Luckily, I was on a city street, not on a highway! Over 18,000 similar year/model cars were recalled for this exact same reason a few years ago (NHTSA campaign number: 15v189000), but not mine. Now I am faced with a $2,400 bill to get it replaced!!”

   • filed 2019–2026

   Owners describe an engine overheating message that appears while driving, followed by the engine idling roughly or sputtering as if it might die. Some complaints tie the overheating to an electric water pump that stopped working, and a complaint describes a coolant leak from the radiator. Owners report being stranded in parking lots or losing power on the interstate, and some had the car towed to an independent shop. Mileage is listed only for a report at about 95,000 miles, and most describe overheating while driving or at low speed.

   2 related service bulletins

   What to check: Check the coolant level and look for leaks at the radiator and hoses, and ask whether the electric water pump has been replaced. Ask whether a coolant vent line service bulletin has been applied, and have the cooling system checked on a longer test drive.

   “I just had a coolant leak problem from my radiator. On my Bmw profil, it is not showing any recall, but knowing that this is not a problem coming from me, I searched online for an answer and found that there is a recall id from NHTSA 18v755000 for engine cooling.”

   NHTSA complaint #11204171, filed 2019-04

   “I was driving on a on a busy interstate after work and out of nowhere I get the Temperature warning and start losing power. This is Dangerous! I am submitting this complaint to report a safety‑related defect involving the electric water pump on my 2014 BMW 320i. This issue is widely documented among BMW owners, and several 3‑Series models from the same production years have been included in recalls or service bulletins for premature water pump failure. …”

   Recall 15V5200001 related service bulletin

   What to check: Ask whether the exterior lighting recall (15V520000) has been completed for this vehicle, and check the bulb holders and harness for heat damage or melted plastic. Ask whether the service bulletin for rear lights that do not work has been applied.

   2 excerpts from owner complaints in NHTSA records

   “Tail lights showed up as a malfunction on the console, I thought it was a bad bulb so I replaced it but while doing so I noticed that the harness and pin from the bulb holder was melt. The weird part about this is that only 1 pin was burnt, after doing research and I found out that this was a common issue with other Bmw. I spoke with many other owners on forums and they experienced the same issue, this isn't just isolated to the 2014 Bmw 320xi but other Bmw vehicles seem to have the same flaws. …”

   NHTSA complaint #11252527, filed 2019-08

   “Recently purchased vehicle. After about a week, had issues with both headlights and one brake light. I replaced all the bulbs. About another week later, headlights work but notifications pop up saying front left and right headlamp malfunction. Rear right brake lamp after replacing bulb however is malfunctioning only after changing it out 1-2 weeks earlier.”

   Transmission and drivetrain

   Drivetrain malfunction messages and unexpected gear shifts

   • 11 complaints (21%)
   • median 63,000 mi at 6.2 yrs old (6 state mileage, few)
   • 3 mention a crash, fire or injury
   • filed 2014–2026

   Owners describe a drivetrain malfunction message on the dashboard, sometimes with shaking, a check engine light, or a loud noise from the engine area. Some complaints describe the car moving or shifting on its own, including gears changing while parked and a car that rolled forward after the gear selector had moved into neutral instead of park. A dealer attributed the independent gear changes to floor mats pressing the accelerator, and another owner received a message to shut the car off, call roadside assistance, and go to the dealer. Where mileage is listed, reports range from about 17,000 to 77,000 miles, and some do not list mileage.

   1 related service bulletin

   What to check: Ask whether the transmission bulletin about shifts into park or neutral after an automatic engine start has been applied, and test the gear selector and shifting on a test drive. Check for stored drivetrain fault codes and any drivetrain messages during startup.

   “Power tran light went on, brakes lost pressure, engine is blown. Looked up this same year/model Bmw and my car fits the recall profile to a tee but my VIN wasn't included on the recall list.

Buying note. Buyers considering this model year may want service records for the timing chain, cooling system, and fuel pump, along with a check for open recalls. A test drive at highway speed and a scan for stored fault codes may help, since many complaints describe problems that appear while driving.
