2019 BMW 430I: engine overheating

Filed Oct 9, 2026 · Engine · CO

The vehicle had previously undergone front-end collision repairs. Seventeen days after retrieving the vehicle, it suffered a sudden, catastrophic loss of engine coolant while driving. The dashboard flashed an 'Engine Temperature High' warning followed immediately by an 'Engine Overheated' warning. Due to immediate road conditions, the vehicle could not be safely pulled over or stopped right away, creating a severe safety hazard. The vehicle became completely undrivable and was towed. Following an independent insurance and shop inspection, it was determined that the sudden failure was entirely mechanical and unrelated to the collision. A diagnostic inspection by an independent service center confirmed a cracked and failed Engine Oil Filter Housing / Cooler Assembly, which had caused the sudden, complete coolant dump.

On my way home driving, my car dashboard and LCD screen give me a warning of overheating and engine oil pressure too low. Car stalled on stalled soon after, and started smoking. So I had the car towed and was told from bmw dealership, I had to get a new engine. I have kept up on my oil change and maintenance and never got these warning signs until now. I did mr research and found out from Kelly blue book and other websites such Dealer Rater that bmw same year make and model have a few recalls including engine cooling and crankshaft sensor malfunction. The bmw mechanic advise the coolant and oil holder made of plastic melted down into the engine and engine needs to be replaced. However, there have been reports states that other have experience the same thing with bmw cars. This should not have happened when much warnings was not given and how ironic same year make and model had the same issue and recall was issued. I have screen shots to prove it.
