2020 Toyota Camry Driver Assist & ADAS Problems

Camera / Radar component - yes Camera / Radar unit is available When it failed, the dash lit up with lots of errors: engine check light, anti-skid failure light (even though the system was turned off), rotating errors included: secondary brake system malfunction, pre-collission system malfunction, LDA system malfunction, check engine. I was driving up a 6% hill on a four lane road at 65 MPH with the cruise control active. Was in the left lane passing two slower trucks when the engine just seem to die and the dash lit up with lots of errors. By the time I was able to get to the right lane and off the freeway, I was doing less than 20 MPH. It turns out that when the radar / camera unit failed, the computer put copious confusing errors and put the engine in limp mode. Very dangerous and I'm lucky there wasn't more traffic. When the computer detected the failure should have automatically disabled the cruise control and put out an error message saying it was now disabled. The other junk errors just confused everything. The computer definitely should not have put the engine in limp mode. It was only after I pulled over and had time to digest the errors that I actually figured out what had happened and how to handle the situation. After I pulled off, the center display which had been saying there was a message that would display after I was safely stopped, now had an message indicating I should turn off the cruise control. Problem was I could not determine if the cruise control was active or not because the indicator was blocked by errors, however the engine was still definitely in limp mode. I finally turned the engine off and back on to make sure the cruise control was off. All the rotating errors and error lights were still on, but the engine was now out of limp mode and the car was again drivable.

FORWARD FACING RADAR SYSTEM MALFUNCTION. IF VEHICLE IS PARKED IN THE SUN AND WINDSHIELD IS HOT THE FORWARD FACING RADAR IS OVERHEATED AND WHEN YOU START THE VEHICLE THE SAFETY SYSTEM FAIL TO BOOT UP. IF THIS ISN'T ENOUGH OF A SAFETY CONCERN THE ERROR MESSAGES OBSTRUCT YOUR INSTRUMENT CLUSTER SCREEN SO YOU CAN NOT SEE IMPORTANT THINGS LIKE YOUR SPEEDOMETER. YOU CAN CANCEL THE WARNING BUT WITH IN A FEW SECONDS IT REAPPEARS AND OBSTRUCTS YOUR VIEW. VEHICLE WAS TAKEN TO DEALERSHIP. THERE ARE NO RECALLS OR SAFETY BULLETINS ON IT FROM TOYOTA CORP AND NO KNOWN FIX. THIS PROBLEM DID NOT EXIST UNTIL TOYOTA MOVED FORWARD RADAR FROM GRILL AREA AND PLACED IT INSIDE WINDSHIELD TOP CENTER. IF I MANUALLY COOL THE AREA WITH COLD WATER OR PROLONGED FAN BLOWING ON THE AREA I CAN RESTART AND SAFETY SYSTEM BOOTS UP FINE. THIS CONTINUALLY HAPPENS OVER SEVERAL YEARS, AND YET STILL NO RECALL. SEVERAL DISCUSSIONS ON TOYOTA'S FORUM ABOUT THIS EXACT ISSUE. YET NEITHER TOYOTA OR NHTSA ARE ADDRESSING IT. LETS RECALL AND FIX THIS BEFORE SOMEONE DIES AS A RESULT OF THE SAFETY SYSTEM MALFUNCTION OR THE WARNING MESSAGE OBSTRUCTING THE INSTRUMENT CLUSTER.

If vehicle is parked in sun the front facing camera and laser located at the top of the windshield overheat then when the vehicle is started the overheated front facing camera is offline so the collision, lane depart/assist and auto dimming system will not boot so those safety features are offline and your screen with your instrument cluster is obstructed by warning messages. If you park in the shade or cool the top of your windshield with water prior to starting the processes boot normally and your safety systems are available. Problem is reoccurring if vehicle is parked in the sun.

My wife was pulling into a parking space, feathering the brake. About a foot from parking, the car suddenly lurched forward, with her foot Still on the brake, and smashed into a 2' high decorative wall. The car is no longer drivable.

FRONT CAMERA DISABLED OR FRONT COLLISION WARNING SYSTEM DISABLED, NOT ABLE TO TURN ON CRUISE CONTROL. THIS HAVE BENN HAPPENING AFTER THIS PAST VERY HOT DAYS, AFTER BLOWING COLD AIR TO WINDSHIELD IT COMES BACK TO NORMAL.

While driving the Camry at 45 mph among the flow of traffic on a state highway in Florida, out of the blue the vehicle's speedometer on the instrument cluster was replaced with a flashing red box and the brakes applied themselves fully with no command or input given whatsoever. The Camry immediately screeched to a stop in the middle of the road within a couple seconds, causing the vehicle behind me to slam into the Camry at full speed. There were no other vehicles or obstacles ahead of me at all, this fact was also observed by witnesses. The automation had triggered for no apparent reason, overriding my control of the Camry and stopping it in the middle of a major highway, causing the accident. Despite the intensity of the crash, the air bags of the vehicle failed to deploy in the impact, worsening the severity of my injuries. Both the Camry and the other motorist's car were rendered inoperable and totaled in the accident, they had to be towed from the scene. The police ruled the cause of the accident to be vehicular malfunction of the Camry.

Several times when I was driving without cruise control down the hill from our home, the car's automatic brake turned on when I passed another car. The car incorrectly sensed that I was going to hit or be hit by the passing car and the automatic emergency brake turned on. Nothing happened except I was startled and puzzled. I was driving less than 30 mph on a residential street.
