There are 3 owner-reported brakes complaints for the 2021 BMW 5 Seriesin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
In November 2025 my breaks quit working. I had AAA haul my car to a repair shop. They ran the codes on the car and found that it was related to a recall on 2021 BMW 540i's for the oil vacuum pump assembly, pan and gasket. I then had it towed to BMW and found out that my vin was not in the recall. BMW quoted me $4587 to repair this on a car with 45,000 miles. I then had it towed to a repair shop that replaced the oil vacuum pump assembly, oil pan, gasket and bolts for about $3700. I think that my vin should have been included in the recall. It was a obviously a common problem with my model and I should not have to pay this much on a car with 45,000 miles. I also had to pay $283.81 for BMW to diagnose it.
We notice the lose of braking power right after we started the car on 4/30 morning. The car was totally fine before that. took it to the BMW dealer they said the problem is "Vacuum/oil pump failing internally. fault for brake booster pressure switch, no brake boost" I find that there is a recall for the exact problem but it doesn't include my vehicle The "Part 573 Safety Recall Report 21V-598" stated that when It does happen it will cause damage to the oil/vacuum pump. I think recall 21V-598 should include my vehicle
