After vehicle is driven for approximately 15 mins or more and then comes to a long stop at a red light or drive thru line (while transmission is in drive and foot is on the brake), idle drops to 500rpm and car starts shaking as if it's about to die. Issue has been ongoing for years even before the fuel pump recall fix was performed but didn't start until around 25 thousand miles. Issue isn't the AC compressor cycling, it is not the secondary/auxillary cooling fans engaging, no check engine lights, no other symptoms. If it gets worse, it could cause the vehicle to completely stall in traffic posing a safety hazard. Shifting the transmission to neutral or park stops the issue. Shifting into neutral and then back to drive temporarily corrects the issue but then it re-occurs after at least 30 seconds or more. Many other 2017 and 2018 Corolla owners have reported this issue as well online and nobody has found the cause.
