Cadillac SRX speedometer drops to zero with transmission issues possibly due to corroded battery cables on Cadillac SRX

Some Cadillac SRX owners report experiencing issues with their speedometer dropping to zero, which can be attributed to various factors such as a faulty vehicle speed sensor (VSS), damaged wiring from water exposure, or electrical problems. Additionally, both generations of the Cadillac SRX have been noted for transmission issues, including hard shifting and premature wear of components like the timing chain. Owners have also reported that fixing a non-functioning speedometer can range from simple solutions, like replacing a blown fuse, to more complex repairs involving the instrument cluster.
