2019 BMW 540I problems

Filed Oct 22, 2026 · Driver assistance, Wheels · IL

In March of 2026 I decided to make use of the vehicles lane keeping assistant and set the lane keeping assistant to maximum safety settings. Within 2 months I noticed the car began to slip l/shudder at the front end while taking highway exit ramps. After this happened a few times I pulled over and checked the front tires because I thought maybe I drove through asphalt oil or something that made the tires slick. Both front tires displayed excessive wear on outside tire edges, almost like someone took a Dewalt power sander and ground the tires down along the entire outer edge that is supposed to grip the pavement. There were no changes to the vehicles suspension or mechanical components leading up to this problem, so I disabled the lane keeping assistant and it appears to have stopped the lose of material on those tires. I have enclosed two photos one clearly shows excess wear on the outer edge. The other pictures of a normal wear and tear of the same tire not used during auto steer or lane keeping and the other photo is of the inside edge of the same worn front tire.

I own a 2019 BMW 540 with B58 engine and I have begun noticing abnormal rattling noise from the engine area, which may indicate early stage failure of the oil pump assembly. There are widespread reports from other owners of failure of the oil pump rotor housing/adjusting ring due to heat-related degradation of plastic components. Failure of this component can lead to sudden loss of oil pressure, drivetrain malfunction warnings, and ultimately engine seizure while driving. Sudden engine failure at speed presents a significant safety hazard due to loss of propulsion and potential inability to maneuver out of traffic. BMW has reportedly updated the oil pump design to an all-metal version around mid-2020, suggesting awareness of a design failure. I am submitting this report as a potential early indicator before catastrophic failure occurs.

On friday, 11/20/20, driving on interstate at about 60-65 miles speed, suddenly within few seconds, the speed dropped down to 35-40 miles without any braking action by me. It scared the hack out of me. I barely managed to get off the driving lane. While in my car, bww sos on-call ( don't know exact name) called, and asked me if I was ok. Then, the operator got roadside assistance or their mechanic online; he tried to diagnose the problem. He said it would need to be towed in to the dealership. The operator arranged for the towing truck; the car was towed in to 'global imports bmw' dealership. The service man tested the car the next day, and mentioned that his test did not reveal anything but thought that this was an unique situation that required bmw's engineer's assessment. Then the dealership wanted/ kept the car overnight, drove, and tested it the next day. That's when they found that the throttle body actuator was faulty. They replaced. I had a similar problem, on a smaller scale, early this year. I had taken the car to the same dealership back then. They didn't find anything unusual at that time. The service advisor mentioned that very likely that problem in early 2020 may also be due to faulty throttle body actuator.

My check engine light came on for chassis stabilization and drivetrain malfunction. I took it to the dealership and they told me they repair would not be covered under warranty. Dealership alleges a rodent gnawed on a engine wiring harness. From what I gather from the dealership this occurs frequently. The manufacturer is aware of this problem but has failed to make necessary design changes to make these wiring harnesses inaccessible to rodents. My case is not the worse case scenario but a fire could have started, my vehicle could have become inoperable and cause an accident while operating the vehicle. I would like to request fmvss be updated to address these product design defects. A wiring harness that can potential disable regular functions of the vehicle could result in death should not be easily disabled by a rodent.
