2012 BMW 535I Problems

What owners report

Owners of this model year most often report stalling or power loss, and many of those complaints are tied to the fuel pump and to questions about whether recall 16V746000 covers the vehicle. Other reports describe the transmission shifting into neutral or staying locked in park, engine timing and internal engine damage, and airbag or restraint warning lights. Where mileage is stated, the fuel-related complaints fall between about 65,000 and 120,000 miles, and many complaints give no mileage.

   “On october 10th, 2020 at approximately 830am, I was driving westbound on the 118 fwy, my 2012 Bmw 535I suddenly lost power. I tried to give it more gas but it would not go faster. It immediately gave me an error pointing to the fuel system. I was able to exit the freeway safely. After being inspected by a certified mechanic, it was determined that both of my fuel pumps need to be replaced. There is a recall for fuel pumps for the 2012 Bmw 535I but my specific VIN number does not fall under the recall. …”

   NHTSA complaint #11366920, filed 2020-10, 71,000 miles

   “While waiting behind another vehicle to make a left hand turn my vehicle stalled and would not restart. However, whenever I opened the door it would start and stop when the door was closed. The vehicle was towed to sloane Bmw of devon, pa. Sloane said the problem was the fuel pump and fuel pump module which they replaced for which I was charged $1585.62. However, this was not the end. On 3/28/19 while passing another vehicle on a 4 lane highway the engine light came on and the vehicle started shaking and decelerating. …”

2. 2
   Transmission and drivetrain

   Stalls, neutral shifts, or transmission locked in park

   • 6 complaints (11%)
   • median 87,000 mi at 7.1 yrs old (6 state mileage, few)
   • filed 2014–2020

   Owners describe the car stalling, or shifting into neutral by itself, while driving or when the auto start/stop system engages at a stop. Some complaints say the transmission stayed locked in park and the neutral override was unavailable, leaving the car blocking traffic. Another complaint describes a shift into neutral at about 40 mph, and a separate complaint describes a power train warning with sudden loss of speed. Stated mileage ranges from about 4,000 to 109,000 miles, and some complaints describe stalls at traffic lights or stop signs with auto start/stop engaged.

   What to check: During a test drive with auto start/stop engaged, watch for stalls or neutral shifts at stops, and ask for any stored fault codes from a dealer scan.

   “While driving at 40mph, my vehicle shifted into neutral by itself and almost caused a major accident. This happened 3 times yesterday and now I'm afraid to drive it.”

   NHTSA complaint #11364323, filed 2020-10, 109,000 miles

   “Several times when starting from a stopped position with the auto start/stop engaged, the car will stop and automatically go into neutral. I have had this happen several times when pulling into an intersection. It happened once while making a left turn with oncoming traffic and the car stalled after I started the turn. I had to get the car back into drive quickly to complete the turn and avoid being hit by the oncoming traffic. This does not happen frequently, has occurred a total of 5 or 6 times in the 4 years I have owned the car.”

   Engine

   Timing chain, VANOS, and internal engine damage

   • 6 complaints (11%)
   • median 116,526 mi at 9.1 yrs old (3 state mileage, few)
   • filed 2018–2025

   Owners describe engine problems linked to timing chain wear, a failed camshaft (VANOS) gear bolt, rod bearing failure, and a piston ring that jammed and seized the engine. Some complaints start with a check engine light and a mechanic's diagnosis of a timing chain that needs replacing. A complaint says a dealer reported a broken driveshaft had fallen into the engine and damaged the oil pan. Where mileage is stated, these complaints fall between about 90,000 and 150,000 miles, and several do not state mileage.

   2 related service bulletins

   What to check: Ask whether the timing chain and VANOS components were inspected, and during a test drive listen for rattling and watch for check engine lights or loss of power.

   “Engine blew a year ago and I had to have that replaced because the rod bearings blew at 90,000 miles. Rear differential has failed not once but 2 times. Failed the first time 11/24/2020 and after $2200 in repairs again on 01/23/2021. Nevermind also having both from cv axles replaced as well. But the rear differential failure I have been seeing on a lot of Bmw's.”

   NHTSA complaint #11389810, filed 2021-01, 150,000 miles

   “3/23/2021 driving on I-94 in morning rush hour when engine killed. Was able to roll over to the median between an on-ramp and the highway before car stopped moving. Charge battery light on on the dash as well as check stabilization warning. Would not turn over at all but dash lights/wipers were on (raining). Towed to mechanic I've taken vehicles to for past 4-5 cars/trucks. It was found that the #2 piston ring came off and jammed between the cylinder wall and piston causing the engine to seize/need to be replaced. …”

   Air bags

   Airbag and restraint system warning lights and sensors

   • 6 complaints (11%)
   • median 49,000 mi at 6.8 yrs old (3 state mileage, few)
   • filed 2016–2025

   Owners describe airbag or restraint warning lights that come on at startup, stay on, or keep returning. Some say passenger seat sensors were inspected or replaced without clearing the warning. A complaint says the manufacturer asked the owner to pay for a seat sensor repair, and another says a faulty passenger sensor could affect airbag deployment in a crash. A clock spring was also replaced after a clicking sound when turning the wheel. Where mileage is stated, these complaints fall between about 43,000 and 92,000 miles, and some describe a warning light that stays on or keeps returning.

   What to check: Check that the airbag and passenger seat warning lights are off after startup, and ask the dealer for the repair history of any seat sensor or clock spring replacement.

   “I had to replace the airbag clock spring in my car because of a clicking sound when the steering wheel was turning any direction, sound heard when vehicle was in drive or park. I had about 43,000 miles on the vehicle when the noise started. I had called Bmw to see if there was any warranty on this item being it is part of the srs system for the car, and they told me for my vehicle VIN there was not. …”

   NHTSA complaint #10938578, filed 2016-12, 43,000 miles

   “The seat mat sensor (airbag) has failed on my vehicle. The item is a known problem and has been recalled on several other years, however it has not been recalled on the 2012 yet. I have contacted Bmw and they refused to acknowledge the existing problem. They want me to pay $1200 to fix the item they know has failed on numerous years. This is a safety issue and they are not resolving it. They told me my case was closed and it would not be investigated any further then my phone call.”

   NHTSA complaint #11122851, filed 2018-08, 92,000 miles

Buying note. Ask for records showing whether any fuel pump repair was done and whether recall 16V746000 applies to the specific VIN, and test-drive the car with auto start/stop engaged at stops. Those stall and warning-light items appear repeatedly in the complaints above, so they are the most concrete things to verify for this model year.

Summary written with AI from a sample of 49 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified.
