Intermittent message displaying "Trailer Brakes Disconnected" while towing. Trailer lights continued to operate even while message was displayed. On average trailer connected and disconnected every 2-3 minutes
Keep getting the messages "Trailer brake error, if towing come to a stop with manual controls" And "Pre-collision system malfunction" The messages go away usually after restarting the vehicle but eventually comes back on
The electrical system malfunctioned, causing all warning lamps on the dashboard to light up. Because this happened while I was driving, I do believe that this electrical issue caused safety concerns for others on the road. The taillights went out first, seconds later, all remaining electrical failed at once, including airbags, windows, headlights at one point, pre collision warning lights, lane departure, and the breaking system failed as well. This caused safety concerns for myself, my passenger, as well as the public because all safety warning sensors failed at once while on the road. The problem has been confirmed by Roseville Toyota, who is a manufacturer, and who currently has the vehicle now, they said that there is definitely an electrical issue and most likely a short of some sort. The warning lamps and messages on the dash lit up one at a time, seconds apart from each other, until the entire dash was lit up completely while I was driving on March 24, 2023.
The seat heater control module has failed causing the plastic to burn and melt, nearly starting a fire. Toyota knows about this but refuses to issue a safety recall.
2019 Tundra: for no reason or indication the vehicle displayed a “Trailer Break Error” and “Pre-collision System malfunction” warning asking me to pull over if towing anything (nothing was being towed) and to contact the dealership. Vehicle still operational however the menus can’t be seen as the warning is consistent.

Intermit message "Trailer disconnect " message causing the trailer braking system to fail when attached to truck. Truck brakes are used to stop trailer at unsafe distances. Several trailers were used to verify. I have attached the fix but Toyota says its warranty issue. This is a "safety" issue. I had my 3 year old son in the truck when i had to apply the brakes and couldn't stop in enough time. The truck brakes could not handle the weight of the trailer hence why the trailer brakes were needed. Please prevent a death.
FLASHING FRONT AMBER TURN SIGNAL LIGHTS ARE NOT ADEQUATELY VISIBLE TO OTHER DRIVERS WHEN DRL OR HEADLIGHTS ARE ON. DUE TO THIS OTHER DRIVERS OFTEN DON'T SEE TURN SIGNAL FROM THE FRONT OF THE VEHICLE.
DRIVING WITH CRUISE CONTROL AT 30 MPH, THE ENGINE LIGHT TURNED ON , AND SUDDENLY THE ENGINE SHUT DOWN, NO BRAKES AND NO POWER STEERING. I WENT TO TURN RIGHT AT THE NEAREST AVAILABLE SIDE STREET SO I WOULD GET OUT OF THE WAY OF TRAFFIC. AS I WAS TRYING TO TURN RIGHT, THE STEERING WHEEL WAS VERY HARD TO TURN AND I ENDED UP ON THE WRONG SIDE OF ROAD AND IMPEDING TRAFFIC. LUCKILY THE ROAD WAS SLIGHTLY UPHILL AND THE TRUCK WAS ABLE TO COME TO A STOP. I THEN APPLIED THE EMERGENCY BRAKE AND TURNED THE KEY TO THE OFF POSITION. I TRIED RESTARTING THE TRUCK TO GET IT OUT OF THE OPPOSITE SIDE OF THE ROAD AND AT THAT TIME IT CRANKED AND IT HAD A STALLED RUBBLE SOUND FOR ABOUT 3 SECONDS AND THEN SHUT DOWN AGAIN. AT SOME POINT THE TRANSMISSION BECAME LOCKED AND THE TOW TRUCK DRIVER HAD TO USE THE SHIFT LOCK RELEASE TO GET IT ON THE FLATBED.
LESS THAN 3000 MILES WHEN INCIDENT HAPPENED. WHILE DRIVING AT 55 MPH ON A HIGHWAY THE DASH SCREEN SAID BRAKE AND A CHIME WAS HEARD. IT WAS LATE EVENING 3 DAYS AGO AND THEIR WAS ABSOLUTELY NO OTHER VEHICLES AROUND ME. MY INITIAL REACTION WAS TO BRAKE HOWEVER I DID NOT. IT ALSO HAPPENED TWO ADDITIONAL TIMES AT ABOUT 45 MPH ON THE FINAL FEW MILES FROM MY HOME. THE INDICATOR DID NOT STAY ON LONG ENOUGH TO GET A PHOTO OF IT. WHEN I RETURNED HOME I FILED A CASE WITH TOYOTA USA. I THEN CALLED THEM THE NEXT DAY. TODAY I CONTACTED THE DEALER ABOUT TAKING IT IN FOR THE TO CHECK. AT THAT TIME THE SERVICE REP ADVISED ME THERE IS A RECALL ON THE PART SENSOR ON THE ANTI COLLISION AVOIDANCE SYSTEM. I RECEIVED AN EMAIL REPLY FROM TOYOTA USA HOWEVER THE REPLY DID NOT PROVIDE ME WITH ANY INFORMATION , OTHER THAN THE CASE WAS GOING TO BE ENTERED INTO THEIR DATABASE. THEY WILL PLACE A FOAMY TAPE ON THE BACK OF THE SENSOR AFTER RUNNING A DIAGNOSTIC ON IT. THIS SEEMS A BIT UNDER DONE AND A BAND AID FOR WHAT COULD BE A SAFETY HAZARD. IF IT IS A WATER ISSUE (NO RAIN ON THE DAY IT HAPPENED AND DIDN'T HAPPEN ON THE WAY TO MY DESTINATION) I RESEARCHED THE VIN FOR THE RECALL AND I RECEIVED "THERE IS NO RECALL ASSOCIATED WITH MY VIN, ANSWER. HOPEFULLY THE NHTSA WILL DO A SIMPLE WEBSITE SEARCH AND SEE THE NUMBERS OF PEOPLE HAVING THIS ISSUE. I PREFER NOT TO HAVE ANY SAFETY ISSUES WHILE TRANSPORTING MY FAMILY IN THE VEHICLE.
WHILE DRIVING WITH THE ADAPTIVE CRUISE CONTROL SET A MESSAGE WILL APPEAR "RADAR CRUISE CONTROL UNAVAILABLE CLEAN SENSOR". THIS MESSAGE WILL APPEAR WITH NO ADVERSE WEATHER CONDITIONS. DUE TO THIS ERROR THE CRUISE CONTROL NO LONGER WORKS AND THE PRE-COLLISION WARNING SYSTEM NO LONGER WORKS. ALSO RANDOMLY A "BRAKE!" MESSAGE WILL APPEAR AND THE VEHICLE AUTOMATICALLY SLAMS ON THE BRAKES WHEN NO EMERGENCY EXISTS CREATING A HAZARD FOR VEHICLES BEHIND.
