The Service Park Assist System (SPAS) is a driver assistance system that can be found on some General Motors vehicles. The SPAS uses sensors to detect objects around the vehicle and can automatically steer and stop the vehicle when parking. The SPAS is designed to make parking easier and safer, but it can sometimes have problems.
Some common problems with the SPAS include false alerts, incorrect readings, and difficulty steering. False alerts occur when the system detects an object that is not actually there. This can be caused by things like snow or rain on the sensors. Incorrect readings happen when the system misreads the size or shape of an object. This can cause the system to steer too far away from or too close to an object. Difficulty steering can occur when the system does not provide enough power to the steering wheel, making it hard for the driver to control the car.
If you are having problems with your SPAS, try cleaning the sensors with a soft cloth. If this does not fix the problem, you may need to take your car to a dealership for service
