NHTSA Complaint #11534232 — 2018 TOYOTA RAV4

I have a similar complaint as NHTSA ID Number: 11210210. On several trips over the past few years, while traveling at speeds of 70 mph, my vehicle would have a loud bang and then start bucking and jerking when I briefly let off the accelerator. About 2 weeks ago, I was looking at my speedometer at the time when the bucking started happening. The EV light came on for a brief second and the needle on the charging gage briefly dropped down into the charging status. It seems that the EV motor was trying to engage at speeds causing the bucking. This seems like to be a major concern when traveling at highway speeds. The engagement of the EV motor at highway speeds is like unintended engine braking that possibly lockup the engine and loss of control.
