Gas Recirculation Valve (egr Valve) problems of the 2020 Acura RDX

- 2020 Acura Rdx aspec purchased apr2020 new - ~2,800 miles when incident occurred on sat, 4jul2020 - was traveling on I-10 west at ~70 to 75 mph - attempted to pass a vehicle (on the left) when car lost all ability to accelerate and orange engine light began to blink in lower left corner of dashboard - I was pushing accelerator to the floor but no acceleration, no engine revving - vehicle slowed down to ~20 mph by the time I was able was able to get over to shoulder safely - turned car off waited ~30 seconds turned car back on and car appeared to function properly - I reported issue to Acura dealership - service rep advised that this is a known issue, but service manager said he knew nothing about this issue - I researched issue and discovered that my vehicle appears to have experienced "limp mode" - as have many other 2019 and 2020 Acura Rdx models - at time of incident was using adaptive cruise control with one bar spacing between vehicles, start/stop was on, comfort mode, always use premium (93) fuel, gas tank was ~1/2 full, weather was clear ~90 degrees - after restarting car realized that had changed to sport+ mode - at this point, I no longer trust the safety of this vehicle - this could have caused a catastrophic accident had there been a fast moving vehicle (e. G. 18 wheeler) behind me - up to and including death - vehicle is currently at dealership for analysis.
