The Jetta has a standard Automatic Post-Collision Braking System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Impreza doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
The Jetta has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Impreza’s blind spot costs extra.
To help make backing out of a parking space safer, the Jetta has standard Rear Traffic Alert and automatically engage the brakes. Subaru charges extra for Rear Cross Traffic Alert on the Impreza and its not available on the Base and the Impreza’s Rear Cross Traffic Alert does not include automatic braking.
Both the Jetta and the Impreza have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights and rearview cameras.
The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Volkswagen Jetta is safer than the Subaru Impreza:

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.
Side impacts caused 23% of all road fatalities in 2018, down from 29% in 2003, when the Insurance Institute for Highway Safety introduced its side barrier test. In order to continue improving vehicle safety, the IIHS has started using a more severe side impact test: 37 MPH (up from 31 MPH), with a 4180-pound barrier (up from 3300 pounds). The results of this newly developed test demonstrates that the Volkswagen Jetta is much safer than the Impreza Sedan:
