For enhanced safety, the front and rear seat shoulder belts of the Nissan Sentra have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Volkswagen Jetta doesn’t offer pretensioners for its rear seat belts.
In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the Sentra are reminded to check the back seat if they opened the rear door before starting out. The Jetta doesn’t offer a back seat reminder.
The Nissan Sentra has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Jetta doesn’t offer knee airbags.
Over 200 people are killed each year when backed over by motor vehicles. The Sentra has standard Rear Automatic Braking that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Jetta doesn’t offer backup collision prevention brakes.
The Sentra’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane. A lane departure warning system costs extra on the Jetta.
The Sentra SV/SR offers an optional Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The Jetta only offers a rear monitor.
The Sentra’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Jetta doesn’t offer a driver alert monitor.
Both the Sentra and the Jetta have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, blind spot warning systems, rearview cameras, rear cross-path warning and available daytime running lights.
The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Nissan Sentra is safer than the Volkswagen Jetta:

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 Nissan Sentra is safer than the Volkswagen Jetta:

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 Nissan Sentra is safer than the Jetta:

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Sentra, with its five-star roll-over rating, is 3.2% less likely to roll over than the Jetta, which received a four-star rating.
For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its available headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the Sentra the rating of “Top Safety Pick” for 2022, a rating granted to only 174 vehicles tested by the IIHS. The Jetta last would have qualified as a “Top Safety Pick” in 2017.
