AI groups complaints by meaning; the groups are approximate. Share ratio compares the problem’s share of this vehicle’s complaints with its share on other vehicles over the last 24 months (shown from 3 recent complaints). A 2× ratio means twice the complaint share, not twice the failure risk. Flags mark unusual shares or recent surges after an AI review of the complaint content. “First signal” does not mean the pattern has persisted continuously.How recall estimates are calculated.
Recalls
NHTSA recall #04V247000May 24, 200451 vehicles affected
air bags
On certain passenger vehicles, incompatible electronic air bag system processors may have been installed.
In the event of a crash, air bag deployment may not occur, increasing the risk of injuries to the driver and/or front passenger.
Remedy
Dealers will inspect and, if necessary, replace the air bag system processors. The recall began june 11, 2004. Owners should contact Bmw at 1-800-831-1117.
NHTSA recall #04V182000April 12, 200413,769 vehicles affected
fuel system, gasoline: delivery: fuel pump
On certain passenger vehicles, under certain environmental conditions, a vapor lock in the fuel pump could occur causing the engine to stall. If this were to happen, the engine would not be able to be restarted for approximately 15 to 20 minutes.
If stalling were to occur, the driver would be unable to maintain vehicle speed or accelerate, increasing the risk of a crash.
Remedy
Dealers will install a resistor in the electrical line powering the fuel pump in order to prevent an occurrence of vapor lock. The recall began may 11, 2004. Owners should contact Bmw at 1-800-831-1117.
NHTSA recall #03V214000June 9, 2003180 vehicles affected
tires
On certain vehicles equipped with 18" tires, it is possible that the tire has been damaged during the mounting process to the rim.
Consequently, a loss of tire pressure, or a tire failure, could occur. Depending on traffic conditions and the driver's reactions, this could lead to a crash.
Remedy
Dealers will unseat the tire from its rim, inspect for any damage, and then reseat the tire to its rim. If inspection reveals that a front tire has incurred damage during the mounting process, it will be replaced. Owner notification began july 14, 2003. Owners should contact Bmw at 1-800-831-1117.
NHTSA recall #03V032000February 4, 20032,635 vehicles affected
seat belts: front: buckle assembly
On certain passenger vehicles, the connection of the safety belt buckle to the steel rope of the tensioner does not meet Bmw specifications. In severe frontal crashes, this connection Can detach.
If the connection detaches, the protection provided by the safety belt is likely to be impaired, and serious injuries to the driver and/or front passenger could occur that might otherwise be mitigated.
Remedy
Dealers will inspect both front safety belt tensioner and buckle assemblies, and if necessary, replace these parts. Owner notification began march 19, 2003. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact Bmw at 1-800-831-1117.
