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.

2009 Suzuki SX4 Owner Comments

SX4 4-cyl

  • 31,000 miles


Two TPMS sensors failed. The first sensor failed at about 31000 miles and was replaced under warranty. Then at around 50,000 miles the second TPMS sensor failed after warranty had expired. The failure is mechanical in nature. The threaded valve stem of the TPMS sensor develops hairline cracks refaulting in slow air leaks, which develop into larger leaks within weeks, which leads to the TPMS warning light going off in the instrument panel, and eventually, in the need to replace to TPMS sensor due to the air leak. Failure to check the tire's air pressure within a day or two can result in a flat tire. There is a great deal of evidence in internet forums that this is a widespread Suzuki SX4 issue, hinting at an underlying fault with the TPMS sensors.
