NHTSA Complaint #11476063 — 2016 MAZDA CX-5

I own a 2016 Mazda CX-5 Touring with AWD. I purchased it brand new from a dealer--no miles on it. It's been a great car until this Sudden Unintended Acceleration problem (about 60K miles now). It's happened 5 or 6 times--twice when in a drive thru. It seems that if I am idling (not pressing on gas or brake) the car will sometimes suddenly accelerate. I have used suggestions to brake, then place car in neutral. That seemed to resolve the problem. However, recently I pulled up to my (rural) mailbox and the car tried to accelerate out of control. I had the brake on (was on a downhill) when it happened, so this was scary. I really had to press down more on the brake pedal, then shifted to neutral, then to park. The acceleration finally stopped. I did not observe tachometer readings during this or other events, but will pay more attention if/when this happens in the future. I do not drive with both feet, and as these incidents have occurred I have been able to maintain more composure and analyze what is going on. I am not getting my foot caught in the mat and I'm not mistakenly pressing on the accelerator. I've been to my local Mazda dealer (Sport Durst in Durham) on May 13, 2022 and they were unable to replicate the problem, so could not repair or even troubleshoot it. The car was T-boned about a year ago, with some damage to the passenger front tire. Could that have anything to do with my problems? My partner feels this could be an issue with the Throttle Control Sensor (hardware) or with the software managing throttle control (much more difficult to diagnose, he says). I wanted to ask: for anyone experiencing this problem, did replacing the Throttle Control Sensor or diagnosing software problems resolve the issue? And, do you have any recommendations for me? Since the car is (barely) out of warranty, (just over 6 yrs/60,000 miles) would filing a claim with Mazda be a good approach? Would you suggest I just trade the car in?
