2020 BMW X3 Engine Problems

70-80k mileage the oil filter housing gushed coolant fluid. Replacement at dealership quoted at $4,000. Dealership indicated they replace part with current part and do not upgrade to an all aluminum to prevent future problems. Employee also stated they are seeing more of these issues of late. The housing has plastic components that fail easily. There was a 2020 bulletin warning of similar failures for this type of engine and vehicle but BMW has not issued a recall. If this draining of coolant is not detected early enough, the engine could overheat and fail, creating a traffic hazard and safety concern to passengers. Local certified mechanics quoted $2,500 for replacement using an aluminum part. These two quotes were from different mechanics and were based on phone conversation, so additional charges may have applied once they began work.they both opined if part is not replaced with aluminum, the part will fail...

The lower radiator blinds/air flaps are not working. I have a check engine light on and the dealership is stating that is what is wrong. This is a known issue with BMW vehicles and has been a recall with other BMW models.

The car has active air shutters on the grill/radiator, which are known to fail prematurely, causes overheating and emissions issues that trigger a check engine light. This was a know issue that BMW issued service bulletin and a 15 year, 150k mile warranty on the part/component up to 2019 model years. BMW did not resolve this malfunction in the same body style car in 2020, and the issue persists. BMW refuses to cover repairs on this issue that they have previously acknowledged and failed to fix, which effects the safety and drivability of the vehicle. There is a class of owners experiencing this issue who are not covered as a result of BMW failing to take accountability for the design failure in 2020+ model years. Estimated repair costs are $1,600 on average. Previous bulletin: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

What component or system failed or malfunctioned, and is it available for inspection upon request? The variable displacement oil pump contains a plastic (Duoplex) internal adjusting ring/vane carrier that is known to become brittle and shatter. Status: While the pump has not yet suffered a total mechanical collapse, it is a documented inherent defect. The manufacturer (BMW) has already superseded this part (Original #11418646454 or ...453) with a reinforced metal version (Part #11419895359), admitting the original material was insufficient for the engine's lifespan. How was your safety or the safety of others put at risk? Risk: The failure mode is sudden and unpredictable. If the plastic ring shatters while driving, it can lead to an instantaneous loss of oil pressure, causing the engine to seize or stall at highway speeds. This creates an immediate risk of: Loss of power steering and braking assist in traffic. Potential rear-wheel lockup (in RWD/Manual...

Beginning Oct 1, 2025. The cars drivetrain warning came on intermittently until mechanics correctly diagnosed the issue. Thermostat valve failed to shut off properly causing the car to overheat. This has been an issue and recall already, just did not include my vin. Now it has happened to me at the cost of 2K and under 45k miles. heat management module had to be replaced due to the danger of overheating and complete car shut down. I am turning this into BMW as well.

The lower radiator blinds had to be replace and was causing the engineer light to come. I feel that this is a big problem with the BMW and should be cover under warranty.

I purchased the vehicle used on December 2, 2023. The vehicle randomly and intermittently exhibits a check engine light in normal driving conditions. The vehicle was inspected prior to sale, and engine oil was replaced prior to sale. The check engine light turns on and off sporadically but seems to turn on when the vehicle switches from electric to combustion engine.

1. Whenever I refill my tank the car will start knocking. It will be only for 1 or 2 sudden jerks. I have tried every grade and nearly all the brands of fuel but its still the same. Even I escalated the same issue when I had my car service done. But to no avail. It happens when I refuel the tank. Otherwise, no issue to my surprise. I Need to know if it’s a known issue? If yes then why no one reached out to me to provide solution for it? Its been years i have tried to escalate it but no resolution. 2. When i use turn signals (either left or right) it start skipping click sound. even when the engine is ON and even when auto engine start is switched off. It happens not all the times but occasionally. I also escalated it when i went for...

BMW recalled our car twice to replace the hybrid battery. Purchase in late July 2020; first recall about August 2020; second recall about September 2021. BMW replaced the hybrid battery as part of the second recall. Since then the vehicle check engine light has intermittently illuminated. The service department has confirmed faults in the hybrid drive system but has not identified the cause of the faults nor identified a fix. The car is not drivable and has been in the shop for the last 6 weeks with no end in sight. This car has been in the BMW service center for issues relating to the hybrid battery drive system on at least 4 occasions encompassing more than 120 cumulative days over the past 1.6 years that we have owned it. BMW reportedly is now replacing sensors (e.g., throwing parts at the car) in hopes of correcting the fault rather than...
