ID: 2098770FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The car has on 5+ occasions had the collision avoidance system shut down (photos of dash showing this are available and have been shared with the dealer). There were no weather incident at the time. Lane following........ same type of thing also shared with dealer. Most disturbing is on multiple occasions, with the speed control engaged driving on the interstate at 65 to 70 mph, the speed limit indicator on the dash changed to 40 (no speed limit change) and the car went into hard breaking mode until I disengaged the system. (also reported to dealer) Each time the car went into the shop, they "checked the systems" and found no faults and made no repair except on one occasion, they "flashed" the software. The car went into the dealer with 67,000 miles on June 3, 2025 with a promise that they would get to the bottom of this issue. The car was returned after a full "testing" and for good measure, one software update and the replacement of a forward facing camera lens. For each item submitted, they reported no history of any faults and found nothing wrong with the car. The car was returned [XXX] at [XXX]. On [XXX] going 60 mph in traffic, the speed limit indicator jumped to 80 mph and the car immediately and rapidly accelerated until I shut the system down. I took a photo of the dash showing the 80 MPH indication. There are NO locations in Virginia that have an 80 mph speed limit. Also, on several occasions, an alert comes up the the car has been in an accident..... when parked in my garage and a bogus date. Other software glitches happen on a periodic basis INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
