NHTSA investigation of STS and CTS differential failures

Consumer Affairs is reporting that the United States National Highway Traffic Safety Administration (NHTSA) is opening an investigation into reported differential failures in 2003-2006 CTS and 2005-2006 STS models. Interestingly, the SRX, which, at least in rear-drive form, should be using the same rear differential is not being investigated.

There are 20 reports from owners of rear differential failures, including 9 that resulted in loss of vehicle control. The reported failures occurred at as few as 3400 miles.

An investigation would be the first step toward a recall – though many investigations result in no further action. A recall could impact over 350000 cars.
