For this item - please refer to nthsa recall 18v-465 : BMW crank sensor recall 9/12/2018. In particular - this refers to a 2018 BMW 540ix. Specifically, "vehicles may have been manufactutred with a crankshaft sensor, that due to sensor firmware, cannot accurately process the input from the crankshaft reluctor ring. Basis for recall population determination: supplier production information was used to identify the start and end date of the affected crankshaft sensors which then correlated with engine production and vehicle assembly information to determine the start date (5/18/2018) and the end date (06/08/2018) of the affected vehciles. " this vehicle was towed to a factory authorized dealership - all aspects of the malfunction mimicked the description in the recall. The authorized dealer confirmed the sensor failure and proceeded to replace the defective crank sensor as per recall protocol. Authorized BMW dealer and BMW customer service have refused 18v-465 recall participation per, "after reviewing your request, the recall you referenced does not apply to your vehicle. Recalls are VIN-specific, and I can confirm there are no active recalls associated with your VIN at this time" repair invoice was paid in full by vehicle owner for the crank sensor replacement. Considering that the issue at hand is a manufacturing failure depicted by a faulty firmware product (sounds like an intermittent or bad production circuit within the crank sensor computer chip), and with this vehicles in question produced just prior to the factory implied recall production date -- might it be possible that the professed faulty firmware (ship) within the crank sensor regulated in 18v-465 may have encountered some early production failures even previous the factory stipulated VIN date of 5/15/2028? would it be advisable at this juncture for nhsta to revisit 18v-465 to include and an all-defective crank sensors encountered that may be a causation for this safety recall? thank you.
I contacted the dealership where I purchased my vehicle called global imports on December 6 because the car was running hot. I arrived on Saturday morning was informed that the radiator was leaking and a water pump was leaking that they both needed to be replaced and I would be charged around $3000 to replace it. There were no recalls the service bulletins that I mentioned they advised me were only repair notifications. They said there were no other notifications regarding the radiator only to have the check engine light come back on a week later I took it to a different dealership and I was advised that the 15 year warranty on the flaps which the flaps are not functioning properly. I was advised to take it back to global imports .
When braking to come to a stop at a light, the engine revved up to over 5000 rpm. I had to shut off the car to get it to stop. When I turned the car back on, it immediately revved up to over 7000, while I stood on the brake to prevent it from moving. Shut it off again, put flashers on and waited a minute. Restarted and it performed normally.
