2009 BMW 535I Problems

What owners report

Owners of the 2009 BMW 535i most often describe sudden loss of power or stalling, usually tied to the high-pressure fuel pump, injectors, or fuel pressure sensors, and frequently while driving at speed. A second cluster of complaints covers rough cold starts and misfires that trigger reduced-power messages; most reports in this sample fall between roughly 40,000 and 130,000 miles.

   Fuel system

   Sudden loss of power / stalling (fuel pump)

   • 49 complaints (69%)
   • median 71,892 mi at 7.5 yrs old (45 state mileage)
   • 4 mention a crash, fire or injury
   • filed 2009–2025

   Owners describe the engine shutting off without warning at highway or city speeds, often with a fuel pump warning on the iDrive screen and a loss of power steering and power assist. Some cars restart after a 10-30 minute cooldown and then behave normally, which owners say makes the failure hard to reproduce at the dealer. Complaints mention high-pressure and in-tank fuel pumps, the fuel pump control module, and pressure sensors being replaced, with some owners reporting repeat failures. Spread from under 15,000 miles up to about 150,000 miles, with most reports above 50,000 miles and many at highway speeds.

   3 related service bulletins

   What to check: Ask for service records showing whether the high-pressure and in-tank fuel pumps and the fuel pump control module have been replaced, and whether any pump-related extended warranty or campaign applied to this car. A scan for stored fuel pressure fault codes is worth doing before purchase.

   2 excerpts from owner complaints in NHTSA records

   “The car shuts off unexpectedly when it's being used because of the fuel pump. I think it's unfair that the 2008 models got recalls up to 10 yrs and 120,000 miles. I feel like the 2009 Bmw xi was missing from this recall. The same high pressure fuel pump was the problem for the recall. I'm both close to reaching my 120,000 miles or the 10 yr mark so it would be amazing to see something being done about this soon.”

   NHTSA complaint #11098713, filed 2018-05, 115,000 miles

   “Car stopped while on freeway moving at 50 miles per hour with my visually impaired grandchild very scary. Warning light came on fuel pump malfunction and car just stopped. Took it to conrad they say it is the high pressure fuel pump and I need to take it to Bmw under recall Bmw says it is the low pressure fuel pump but they are not sure it will fix the problem. Bmw need to fix this problem I thank god we were not hit yesterday on the freeway.”

   Engine

   Rough running, misfires and reduced power

   • 29 complaints (41%)
   • median 70,000 mi at 6.6 yrs old (27 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2009–2023

   Complaints describe the engine running rough or shaking at idle and under acceleration, the check engine light coming on, and a reduced-power message that limits acceleration until the car is restarted. Dealers commonly replace fuel injectors, spark plugs and ignition coils, and some owners report the same symptoms returning after those repairs. A few owners link the behavior to cold starts or to the automatic transmission downshifting. Reported from about 8,000 miles to 130,000 miles, with several cases under 20,000 miles and others in the 70,000-120,000 range.

   4 related service bulletins

   What to check: Ask whether the fuel injectors, spark plugs and coils have been replaced and whether the injector emissions campaign was performed on this car. On a test drive, watch for rough idle, hesitation or a reduced-power message.

   “On an early cold morning, I crank my car and after it started I noticed that my check engine light came on; it stalled out and I had to restart it. This car has been in and out of the repair shop (Bmw) within the last year approximately four times. The major reason was fuel problems. I had a diagnostic test done on it and the Bmw repair shop stated that I needed all injectors, spark plugs and a fuel inlet valve replaced which will cost about 2200. …”

   NHTSA complaint #10559223, filed 2014-01, 75,434 miles

   “In the 4 1/2 years that my 535xi has been in service, the fuel injectors have needed to be replaced 3 times (sept 2011, jan 2013, and sept 2014). The problems have manifested themselves when driving on highways and the vehicle loses most power and begins shaking and the check engine gases light comes on. The most recent time occurred while on an interstate tollway between exits 15 miles apart making for a dangerous situation as I lost speed and any ability to accelerate. …”

   Engine cooling

   Coolant loss, overheating and water pump failure

   • 10 complaints (14%)
   • median 79,996 mi at 10.2 yrs old (8 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2013–2023

   Owners report coolant disappearing quickly, the engine running very hot, and oil or burning smells from the engine bay. Some complaints describe an electric coolant pump failure and, in one case, an engine bay fire attributed to the cooling fan area. Others mention oil leaks from the oil filter housing and valve cover gaskets found during servicing. Mostly reported between about 80,000 and 155,000 miles in this sample, with a few noted at much lower mileage.

   4 related service bulletins

   What to check: Check for coolant residue, low coolant level, and oil weeping around the oil filter housing and valve cover. Ask whether the electric coolant pump has been replaced and whether the pump-related settlement work was done.

   “Bmw 2009 535 xi owner. Out of all of the times taking the car for service for various reasons, I decided to look for information regarding my latest issue. Twin turbo. I was told the rear turbo was bad and it is recommended to do both. I had the car serviced in october, they told me the oil smell was due to the spring from oil cap missing. …”

   NHTSA complaint #11301285, filed 2020-01, 40 miles

   “As I am driving my Bmw after 5 minutes of start it. I smelled oil coming out of the engine. Even after not drink the car for about one week the smell was still there. I am concern that something is wrong with the engine. Even on a cool 60 degree day the engine is too hot to touch. I feel that the coolant in not going to the engine since after putting a full amount of coolant the coolant is deplete after one hour.”

   Transmission and drivetrain

   Transmission failsafe mode / harsh engagement

   Mentioned in 4 of 60 sampled complaints

   Complaints describe the transmission warning light coming on and the car dropping into a failsafe mode with no acceleration, sometimes while merging or accelerating from a stop. In several cases the car shifts normally again after being shut off and restarted. One owner reports a harsh delayed engagement when accelerating from a stop with a cold engine, and another reports complete transmission failure. Reported from roughly 70,000 to 130,000 miles, with one report at very low indicated mileage.

   2 related service bulletins

   What to check: During a test drive, check for delayed or harsh engagement when pulling away from a stop with a cold engine, and ask whether transmission software updates or a mechatronic service have been done.

   “I believe using the manual shift mode for normal usage of optimal shifting in certain driving situations and gentle downshifting caused a malfunction in the functionality of the transmission that led to a complete transmission failure. I don’t believe it’s a mechanical issue or result of misuse. There were no warning signs. Only that every time the manual shift option was used, it would cause an error to occur that caused an automatic shifting issue that would reset if the vehicle was shut down and restarted.”

   NHTSA complaint #11672707, filed 2025-07

   “While driving engine failure, reduce power light came on, power on engine reduced but drivable. When car shut down and restarted light goes off but if stepping on the gas hard the light comes back with engine having reduced power. This was repaired twice, last by Bmw on 7/29/13, they replaced vans solenoids (intake and exhaust) and reprogramed the transmission. At that time they told me if the problem returns the transmission may need to be replaced. …”

Buying note. Service history matters more than mileage here: ask specifically about fuel pump, injector, coolant pump and taillight recall or campaign work, and have a pre-purchase scan done for stored fuel pressure and misfire codes. Given how often these cars stall or drop into reduced power, a thorough test drive and a documented repair history are the most useful things to review.
