NHTSA Complaint #11500621 — 2021 ACURA TLX

My wife and I were on the first day of vacation, driving from Virginia to FL by way of SC. Around 1pm I was driving the car on interstate 20 West in South Carolina near Bishopville. There were no cars in my lane in front of me and the car suddenly activated what Acura refers to as the CMBS system. The purpose of this is to stop us if it thinks we are going to run into another vehicle. I'm not 100% sure but I think this is related to the adaptive cruise control. We had not used cruise control that day because traffic on rt 95 South was extremely heavy. We had finally turned off on Rt 20 and traffic wasn't as heavy so we felt we could safely use the cruise control. We were traveling at about 73 mph and the car suddenly started hard braking. It was flashing BRAKE in big letters in the dash. There was another vehicle behind so I kept pushing on the gas pedal to keep going but the car literally would not release the brakes. The vehicle from behind hit us. There is a video cam in my car so I have a video that shows the car traveling smoothly then all at once bouncing and jerking as it keeps applying the brakes. We also have photos of the front of the car showing that the cameras that this system uses were clear and unobstructed. The other driver was charged but it was absolutely the fault of the Acura for this malfunction. Acura Roadside Assistance tried to tell us how to disable this system but the info they provided was for another year model and didn't work. We went on YouTube and found the correct information and have disabled this system. There were other videos on YouTube describing this exact issue with this system failure with Acura vehicles. We have also filed a report with Acura Customer Care. It is case #[XXX]. We have also reported this to our insurance company (Travelers) and to State Farm, the company that is handling the claim for repair. The State Farm Claim # is [XXX].
