Unintentional acceleration.First, I was in line at car wash proceeding slowly ahead as directed in line. Foot on accelerator lightly moving, when car surged rapidly hitting back end of Tesla about 6-8 ft ahead (2/26/26 12:30pm) Impact strong enough to push Tesla into truck hitch damaging it front of it as well. Applied brake, but impact was too rapid. Second incident with my Volvo was a month later(3/22/26 about 10:30 am) and my husband was driving. . Made right turn on green light and started to accelerate when it revived and surged forward until applied brake. Dealer could not replicate. No codes but repair shop had to recalibrate after 1st incident and may have lost code on 1st incident(wreck). Now that insurance knows what happened, I don't know if they will intervene. hopefully. No warnings went off or messages. Airbag did not deploy. I believe that this is an unintentional acceleration, especially occurring twice now. Dealership says car is safe and they will monitor. I guess it means when we have another incident. Hopefully not fatal to us or anyone else. Dealer says it is a transition from hybrid electric to gas. But I have had this car 4yrs10months and this never happened until now. And the transition never has thrown me back in my seat or had the engine rev. The battery was replaced last August because of bad cell and recall on it for fire hazard. Maybe this could have an affect. On first incident I was in shock so thought maybe in hit accelerator ins
