Passenger door lock will not unlock with the key fob or the interior switch. All other locks respond appropriately. The door will open manually with the interior handle. I replaced the lock actuator with no improvement. I am now trying to replace the electrical relay. The date below is approximate. I am the original purchaser. I have not been happy with bmw service department.

The central locking system does not work correctly. It operates the glove box, passenger and driver doors as well as gas cap door. It does not respond properly to fob or by key. At times all locks are frozen to the point where you can not open to get in or gas. Right now passenger door has been locked for 30+ days. Cannot open at all. Took to a mechanic who ordered a new actuater from bmw dealer, first one did not work. Second one installed and the problem is not solved. ($240.00). Mechanic tells me that something is burning and I must take to dealership. I can smell the burning and I am afraid and will not drive. Looked up on internet, there are 100s of consumers with the same issue. This car only has 71,000 miles on it.

Air bag warning light has been on for three years. Have had 3 tests incl lieth bmw test that verifies it is the passenger side occupancy sensor mat. This defect is a known problem in many bmw models. Bmw refuses to fix it yet requires me to do these diagnosis (for a fee) over and over. Not only that - they have drastically raised the price to repair to >$1400. I seriously question the safety of the car and feel bmw uses the issue as an opportunity to make high profits off the safety concerns of its customers.

When steering sharply or turning the wheel frequently like to parallel park for example, the electrical suddenly completely shuts down in my car. The car's power completely dies and I lose ability to steer. Sometimes this is while making a quick turn with oncoming traffic approaching quickly. I must stop turning, wait for the power to turn back on, and resume driving as soon as possible. This is very dangerous and I am scared to drive my car.

The problem is that the steering wheel does not return to center without considerable assistance. The problem is definitely worse when car is "warmed up" and is also worsened by increased outdoor temperature. This is a real safety concern. My dealer charged me $104.00 for diagnostics and told me to keep the battery charged. This has had ne effect on the problem.

The power steering assist has failed on the car making it very difficult to steer. Luckily it failed while on a straight part of an interstate as my daughter was driving the car and this severely frightened her. She did not overreact and we took appropriate measures to get the vehicle home. Online research indicates that this issue was being investigated by the federal safety agency in 2010 but can not find any indication that an actual recall is in place. This is a very dangerous thing to happen, especially in a state with a lot of winding roads (tennessee). I purchased the car used last year and also had a water pump failure that resulted in a blown engine. I wish this issue had been investigated also as I understand that it is a common failure with this particular engine. There is also a problem with the speedometer and fuel gauges reading incorrectly. I read that one owner was contacted by bmw north america after they filed a complaint regarding the power steering with the federal safety agency and bmw voluntarily fixed the problem for the owner. I hope I have the same luck after posting this complaint. Thank you.

My steering wheel light goes on then the car handling becomes very difficult to control. The problem started one day on the highway. The wheel was suddenly hard. This problem happens several times a day: when I start the car and at any random time while I'm driving. I have to restart the car in order to get the power steering back (before the next failure). This is very dangerous since nothing is telling me when the next issue is going to happen. I'm always scared to make a turn or to change lanes.
