2021 ACURA TLX Forward Collision Avoidance Automatic Emergency Braking Problems

I was traveling on the highway (on a very rainy day), when my car's green signal lights and orange engine light began blinking. Immediately, an orange warning sign on the dash read, "Some Driver Assist Systems Cannot Operate, Radar Obstructed". A few seconds after that occurred, I accelerated to pass a vehicle & as soon as I switched lanes to get over, my car went from speeds of about 85 MPH, abruptly down to 15-20 MPH. My safety was immediately put at risk as the driver I passed began tailgating me as if my actions were intentional. I attempted repeatedly to speed up, but my car just wouldn't go any faster. Once, I proceeded to get in the right line, I was almost hit by a group of tractor trailers. I called my spouse in a panic, who advised me to get off at the next exit. I followed his...

On two occasions the Collision Mitigation Braking System (CMBS) has improperly activated with HARD braking leaving me fighting for control. On one occasion, I was driving at 35 MPH on a divided boulevard in my home subdivision with no vehicles in sight. The second occasion occurred on the Florida Turnpike at 75 MPH while in the outside lane. There was no vehicle in front of me or to the side at that time. That was a scary moment.

First to Fountain Acura in Orlando who could find no DTC codes and blew me off by telling me it was my E-Pass transponder and window tint that caused the problem. That was utter nonsense. The second time I took the vehicle to AutoNation Acura...

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...

In many instances while driving about 40-60 MPH and with no vehicles in front the car would suddenly brake.
