I purchased a 2025 EX90 on XXX. Immediately upon purchase, nearly every time my [XXX] daughter was riding in the middle seat using the integrated booster, the car would alert me that someone was sitting in the other two seats on either side of her. There were also occasions when only one seat alarm would go off. I checked her positioning to confirm that there was nothing on those seats. I took it into the dealership the following Monday. They did a software update, which they stated would resolve the issue. I picked up the car on the evening of XXX. For the next couple of days, it appeared that the issue had been resolved; however, it returned within a couple of days. Additionally, there were two instances, after receiving the car back from being repaired the first time, in which my daughter was riding with me, and her seatbelt failed to engage during rapid deceleration. I was driving on a main arterial street near our home, traveling approximately 35-40 mph. I was using single-pedal mode (EV) and took my foot off the gas pedal to prevent a crash. The car stopped very quickly, and she was thrown forward, nearly missing hitting her head on the back of the passenger seat. Subsequently, while driving the same minor child in a dealership loaner XC90, we experienced a routine quick stop at a very slow speed, and she immediately noted that the XC90 seatbelt was properly tightened. This side-by-side comparison confirms that the EX90's occupant restraint system failed to deploy during a near-crash event. I returned the vehicle on XXX, and the card has been there since. On XXX, Volvo Corporate Engineering reviewed the data and confirmed a diagnosis of faulty radar sensors in the second row. Because the EX90's computer-controlled safety belts rely on these second-row sensors to work properly, this diagnosis from Volvo proves the safety systems in my daughter's row were actively broken during our near-miss collision event. The vehicle is unsafe. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
