Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2004 BMW M3 Owner Comments

problem #4

Faulty smg pump possibly caused by a culmination of other failing parts in smg system. Car is rendered inoperable in potentially hazardous driving situations that would otherwise be circumvented by a system more capable of warning the owner of an impending failure. The remedy the majority of dealerships are using are replacement of the entire smg system, which costs up to $7,000. As hideous as this sounds, there more than likely is a very small factor or part that is causing the entire system to fail. BMW needs to address this immediately.

Vehicle drops out of gear randomly. As I was taking a left turn, the vehicle dropped into 0 gear and on coming traffic almost ran into me head on. I had no way of moving the car due to transmission being shifted into neutral. This is due to a defective temperature sensor on the smg pump. BMW ignores the issue.

This is the second time this happened to my car the smg (sequential manual gear) light comes on and then my service engine light comes on as well every time in that order, also my car shifts itself into neutral all on its own and I can, T control the acceleration on the highway or anywhere else so the car begins top slow down, many people have addressed this issue to BMW N.a. and nothing and it only happens during hot weather, and BMW ran a diagnostic on my car and they gave me multiple things that can cause it so they expect me to pay for all of them even if they are not all the culprits. This is a very dangerous issue especially on the highway and I have kids so it makes me even more worried that something might happen because of this and BMW's negligence to the issue.
