'07 Equinox jerks when stopping
I bought an '07 Equinox recently. The previous owner had it sitting for 5 or 6 months. I am having an issue. The Service Tire Monitoring System and Service Stabilitrak warnings are on. The ABS light was on for a week and suddenly went out. The TPMS isn't registering my rear tires. When I drive over 40-45 MPH and step on the brake at a light sometimes the car will jerk. Kind of feels like I ran over a small bump. Sometimes it's hardly noticeable, others it shakes the whole car. Any ideas?? No check engine light and no other issues with the Equinox.
