On Sunday, March 15,2026, I was driving from Houston, TX to Pharr, TX at the speed of 75mph on the left lane to pass an 18 wheeler, with another 18 wheeler behind me, and my truck started idling erratically. I lost speed and my service engine light came on. My truck slowed down and I almost got in a car accident with the 18 wheelers because the truck did this. The truck behind me slowed down on time and it went immediately to the right lane to avoid hitting my truck. I feared for my life. All the vehicles behind me and the 18 wheelers also went to the right lane to avoid me. By this time, the TRAC light had already come on also. I managed a space of no vehicles and steered towards the right safety lane. I pulled over at the local truck stop and stoped my truck to rest. After about 5 minutes I tried starting my truck and it wasn’t starting. I am a little mechanically inclined, so I started troubleshooting the truck. My code reader gave these codes: P1605-00, P0300-27, P0300-85, and P0302-00. Unscathed to start the truck after a while and got back on the road. The drive was brutal, as the truck kept burping erratically, but I made it home safely. I took my truck to the mechanic and he did some repairs and told me the issue is the fuel pump. I have checked the recalls for my truck but it shows zero recalls for my truck. Luckily I am alive to report this life threatening safety issue that Toyota has on this model. How do I get Toyota responsible to make the repairs on my truck? The part alone is over 1200 at O’Reily auto parts.
While traveling with cruise set at 62mph and a truck was in the right turn lane the automatic collision went off and hard brake when nothing was in front of the truck this has happen also with out cruise control on pulling up to a stop light and being first person no other vehicle was on the road I also don't have forward collision turned on or lane departure
The contact owns a 2020 Toyota Tacoma. The contact stated while driving approximately 80 MPH, the brakes activated independent of the driver input and the vehicle slowed to 60 MPH abruptly. There was no warning light illuminated. The vehicle was not taken to a dealer to be inspected. The manufacturer was not informed of the failure. The failure mileage was approximately 20,000.
THIS MORNING I ACTIVATED MY CRUISE CONTROL (CC)AS I NORMALLY WOULD AT 55 MPH. IMMEDIATELY MY TRUCK BEGAN ACCELERATING UNTIL I FINALLY DISENGAGED CC WHEN THE SPEED REACHED 83-85 MPH. IT WAS STILL ACCELERATING AT THE TIME I DISENGAGED IT. I ATTEMPTED TO RECREATE THE INCIDENT WITH NO LUCK. BEFORE THE INCIDENT, I WAS DRIVING IN A CITY ENVIRONMENT AT SPEEDS LESS THAN 55 MPH, SO THERE WAS NO WAY I HAD PREVIOUSLY SET THE CC TO A HIGH SPEED THAT WOULD HAVE CAUSED THIS TO HAPPEN HAD I HIT RESUME.
SYSTEM WILL OCCASIONALLY SUDDENLY DECELERATE AS I AM PASSING, USUALLY A LARGE TRUCK. I WILL BE IN ADAPTIVE CRUISE CONTROL AND AS I GET ABREAST OF THE TRAILER, THE VEHICLE WILL SUDDENLY DECREASE SPEED BY 10-20 MPH, THEN ACCELERATE BACK TO THE SET SPEED. THIS, OBVIOUSLY, HAS THE POTENTIAL TO CREATE A REAR END COLLISION IF SOMEONE IS FOLLOWING AND NOT PAYING FULL ATTENTION, ESP IF THERE ARE MULTIPLE CARS FOLLOWING. THIS HAS HAPPENED MULTIPLE TIMES.
THE PRE COLISION SYSTEM IS FAULTED OUT DUE TO THE SENSOR BEHIND THE WINDSHILD
