Vehicle hits a bump in the road and the check engine light comes on, followed by the gas pedal being non-responsive and an error code on the instrument panel saying “Brake Override System Malfunction. Check with dealer.” and “Pre-collision System Malfunction. Visit your dealer. ” When this occurs, have to coast the vehicle to a safe place, turn off and wiggle the Radar Control piece attached to the front grill sometimes multiple times before the truck will clear the code and accelerate. Been an ongoing issue for several months. Have replaced the front grill sensor and plate and the issue persists.

Tl* the contact owns a 2018 toyota tacoma. The contact stated that while driving at various speeds, the collision avoidance system activated without a vehicle in close proximity. The contact stated that the lane assist warning light also was inoperable. The vehicle was taken to bill wright toyota located at 5100 gasoline alley dr, bakersfield, ca 93313, (661)398-8697, to be diagnosed. The mechanic was unable to retrieve a fault code or duplicate the failure. The vehicle was not repaired. The manufacturer was contacted and informed of the failure. The approximate failure mileage was 3,000.
Tl* the contact owns a 2018 toyota tacoma. While driving 72 MPH with the cruise control activated, the speed erroneously increased to more than 90 MPH. Also, the collision avoidance system malfunctioned and did not slow down or stop the vehicle when approaching a second vehicle. In addition, while the cruise control was activated, the vehicle would suddenly decelerate after the cruise control erroneously deactivated. The cause of the failures was not determined. The local dealer (chatham parkway toyota, 7 park of commerce way, savannah, ga) was contacted. The manufacturer was not notified. The contact indicated that the vehicle was previously serviced to repair a wave radar sensor. The failure mileage was 12,957.
Pre-collision warning system is faulty. The system engages when nothing is in front of the vehicle to merit warnings or engaging the brakes automatically. However, the system does not engage when the truck is extremely close to the wall of a garage. Unfortunately there is no way to turn off this feature and it will ultimately result in an accident which may be fatal.
The 2018 toyota tacoma has a pre-collision system that does nothing more than beep loudly at the driver when it "thinks" I need to brake. It is overly sensitive and serves as a dangerous distraction whenever I am in heavy traffic. As an example, on tight city roads with cars parked on both sides it detects the cars on both sides and constantly goes off. It detects guardrails and signage on curves. I was told before I bought it that it can be shut off, but that was not really true. It can only be turned off for the duration of the drive. It resets to on at full sensitivity whenever I restart the truck. It is extremely unsafe, as it distracts me in traffic and draws my attention away from the road and to the dashboard every time it beeps. So, I have to go into the dash menu and shut if off every time I start the car, or I'm forced to fiddle with it on the fly in traffic. It is unconscionable to put something like that in a vehicle and not allow the driver the option to permanently disable it. I complained to toyota (case#1807122684) and told them that this represents a serious defect/design flaw and that eventually it was going to cause me or someone else to get in an accident, and they didn't care. They maintain that somehow constantly distracting the driver is a safety feature and that the truck is supposed to do this. As more of these features become standard the ntsb has to regulate them and force manufacturers to consider that not all drivers are the same. There are people that are very sensitive to beeps and alarms and these devices are the opposite of helpful in those cases. They are dangerous. Maybe this "feature" helps some drivers, but to me it is an accident waiting to happen. There needs to be a way for the driver to permanently disable these types of features and maintain control of the vehicle
