THE FRONT COLLISION SYSTEM DOES NOT WORK. EARLY WARNING RARELY COMES ON, AND IN A RECENT NEAR CRASH ON THE DALLAS NORTH TOLLWAY, IT NEVER CAME ON.

I have owned my 2020 BMW m340iX for 2 years. During that time I have had 5 tires blow out, including 3 in the past 3 months alone.

Oil pump appears to have failed. Told plastic components inside pump. BMW issued a new part number and changed pump to all metal internals. This is standard on later production dates now. Pump failure causes engine failure and oil gauge failure to read out. Head gasket replacement which may or may not be related.

Electronic oil level sensor can’t read oil level. Vehicle is currently at the mechanic shop getting the oil pump replaced. It’s costing me around $2,500 out of pocket since I don’t have a active warranty anymore.
