NHTSA Complaint #11470163 — 2013 ACURA TSX

After the harness is clipped in place and tightened as directed, you can pull the straps forward (including my 3yo child was able to do this) and loosen the straps of the harness without pressing on the release button. The harness pulls loose and will not stay locked in place. I also tried to simulate impact with a sudden and strong pull on the harness to see if it would lock in that situation and it does not. If we had been in an accident using this car seat, my child could have been seriously injured because the harness would have failed to lock. We purchased this in Sept 2019 and just noticed this occurring now but unclear if we just didn't realize it before or if the harness just failed now.
