I've got a 2015 Model S 70D that I purchased in July 2020 and have been having this problem for some time. I did the MCU1 to MCU2 upgrade, but I swear it was happening before I upgraded. Had been using a Note 9 since I got the car. Did a factory reset on that phone hoping it would solve the problem. . .it didn't. Last week upgraded to the S22 Ultra (this phone is amazing, but that's a post for a different forum). I was sure this would solve the problem. . .it didn't. Practically every time my wife texts me, it also displays an old text from her "You never brought in the cat litter. . .and I need the party lights." It makes me feel lame, like I'm constantly not living up to her "cat litter and party lights" expectations. If we ever renew our vows, I will promise to bring in the cat litter AND get her the party lights! I also get random texts from different people but that one from my wife when my wife texts me is almost a certainty. Some have suggested to deleting these old texts. Interestingly, these texts are not in my text history AND I'm using a different texting platform (Previously Pulse messaging, not Google Messages) on a new phone. This has me thinking that these old messages are stored in the car's memory somehow. Is there some way to purge the memory (aside from hard reset, which I've done).
