Hello, I own a 2015 Lexus NX200T. On 9/13/2025 I was pulling into a spot to park, going slow at maybe 4-5 mph, my vehicle suddenly violently accelerates on its own. I had to slam multiple times on the brakes to avoid killing two pedestrians right in front of my vehicle. I was in seconds of killing them and pinning them between the vehicle that was in front of me. I did everything in my power to keep hitting the breaks as hard as I could until it stopped within inches of the two pedestrians. This was extremely dangerous and could have killed a mother and daughter in that split second. This appears to be a case of unintended acceleration, which I understand is a serious safety issue. I've been told by both the dealership and Lexus that because no damage occurred, it's not their problem. But this is clearly a safety defect, not just a maintenance issue. I would like Lexus to take this very seriously. I was shaken and very scared. I have NEVER had this happen before. Lexus suggested that the floor mats may have got caught - NO absolutely not. I have the mats locked in place with clips. I did not hit the accelerator instead of the breaks as that is what is assumed. No external damage occurred, but the unintended acceleration was violent. This incident took control away from me. Even though no accident occurred this time, the potential for injury or death is very high. I contacted Lexus and the dealership, but both declined to inspect the vehicle, stating it was not their issue because no damage occurred. I believe this a very serious safety defect that should be investigated. I am requesting NHTSA to investigate this potential defect in the Lexus NX200T model. If other owners experience the same, this could indicate a widespread safety problem. I was very lucky I did not kill anyone; it would have changed the day's events forever for the lives of two innocent people and myself. I don't feel safe to drive the vehicle after this incident in fear that it could happen again.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2015 Lexus Nx300 verdict →
