For enhanced safety, the front and rear seat shoulder belts of the Honda Civic 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 Acura ILX 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 Civic are reminded to check the back seat if they opened the rear door before starting out. The ILX doesn’t offer a back seat reminder.
The Honda Civic 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 ILX doesn’t offer knee airbags.
Using vehicle speed sensors and seat sensors, smart airbags in the Civic deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions. The Civic’s side airbags will shut off if a child is leaning against the door. The ILX’s side airbags don’t have smart features and will always deploy full force.
Over 200 people are killed each year when backed over by motor vehicles. The Civic Touring/Sport Touring has a standard Low Speed Braking Control that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The ILX doesn’t offer backup collision prevention brakes.
The Civic’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 ILX doesn’t offer a driver alert monitor.
Both the Civic and the ILX have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, available blind spot warning systems, rear parking sensors and rear cross-path warning.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the Civic, with its five-star roll-over rating, is 1.2% less likely to roll over than the ILX, which received a four-star rating.
For its performance in IIHS driver-side and passenger-side small overlap frontal, moderate overlap frontal, updated side impact, headlight, and daytime pedestrian crash prevention testing, the Insurance Institute for Highway Safety grants the Civic the rating of “Top Safety Pick” for 2023, a rating granted to only 53 vehicles tested by the IIHS. The ILX last would have qualified as a “Top Safety Pick” in 2017.
