What 2005 BMW 5 Series owners say
Air bags
Tl contact owns a 2005 BMW 5-Series. The contact stated that the air bag and seat belt warning lights illuminated. The vehicle was taken to the dealer where it was determined that the front passenger seat sensor mat needed to be replaced. The vehicle was not included in NHTSA campaign number: 08V384000 (air bags). The vehicle was not repaired. The failure mileage was 71,000.
On 12/5/2011 - when I started the car, I noticed the message on my dashboard indicating a fault on passenger restraint system. There was not any incident that I can recall that would result in the error message. After further research, I discovered that the error message was a common fault on these type of cars due to a faulty mat sensor located under the front passenger seat. I also found out that there was a recall for some BMW cars of the same model (dependent of VIN). My husband immediately called BMW of fremont (northern ca) to inquire about the recall and I was told by the service advisor that he was not aware of such recall. I use this car daily to drop off our kids to school. I honestly think the issue really poses a serious threat on my kids safety since there is a high possibility that the air bags will not deploy in case of an accident. …

On September 14, 2005 I purchased a new 2005 BMW 330i. While driving to work on December 1, 2005 I turned the heater on for the first time. The heater had only been on for a few minutes when I started to smell a burning type of odor. I was not sure if the odor was coming in from the outside or if it was inside my car. The odor became stronger and resembled that of an electrical burn. I then observed white smoke coming out from the hood of my car. Within minutes the smoke became gray. At this point I was in heavy early morning traffic. I was in the middle lane which was slowing down/stopping for a traffic light. As I came to a stop the smoke was turning black and was very thick. I put the vehicle into park and turned off the engine. By this point visibility to my front was obscured by the smoke. I knew that I should exit the car. …
