While in the number 2 lane on the freeway, using cruise control, we approached a semi truck in the number 3 lane. we were moving more quickly than the semi truck and did not change lanes nor did the semi truck. the freeway was straight. the automatic braking system turned on and engaged the brakes when our car reaches approximately the rear axle or is next to the back middle of the semi truck. brakes engage in the same fashion they do as if there was a hazard in front of us. to be clear, nothing at all is in front of us, just the semi truck to our right.
Takata recall having an issue with acc or adaptive cruise control, info screen says acc not available, this is second time happening, first time dealer said it just needs calibration, it just happened again. the car is still under warranty, once it expires and it happened again, it will be out of pocket expense. please take action to this matter, multiple people been having same issue.
