I am having a recurrent problem with my 2018 Sequoia in that I am consistently getting warning lights and alarms going off for 'brake warning, ' rear cross traffic alert, 'blind spot monitor malfunction' and 'front camera malfunction.' It has been in the shop 5 times and they keep saying there are computer gliches and keepnupdating the software over and over again. Toyota sent down a tech from denver to take a look at it and instead of repairing the problem, they have disarmed all of my alarms because what they said was that they were set too sensitive"! this is a huge safety issue as two of the times that the 'brake warning' flashes the truck starts to slow itself down. What if this happens when an 18-wheelerbis behind me? the brake lights don't come on to let them know that my vehicle is slowing down!! I am very scared of driving this vehicle and Toyota says it's safe to drive" I'm at a loss as what to do now given that all of these software updates are being done and alarms are disabled I feel like I'm driving in a vehicle that is unsafe!!

The contact owns a 2018 Toyota Sequoia. On several occasions, when the vehicle was started, the adaptive collision warning sensor illuminated. The contact stated that the vehicle was turned off and back on, and the vehicle would reset itself. The failure recurred several times. On several occasions, while driving various speeds with no other vehicles ahead, the auto braking feature independently activated and the "brake, obstacle ahead" warning message illuminated. The vehicle would then suddenly brake independently. The vehicle was taken to the dealer (hoover Toyota, 2686 john hawkins pkwy, hoover, al 35244, (205) 978-2600) where the forward facing cameras and sensors were replaced; however, the failure recurred. The contact stated that several warning indicators illuminated at times, including the blind spot monitoring system malfunction, adaptive collision sensor, brake obstacle ahead warning indicator, and adaptive cruise control. The vehicle was taken back to the dealer to be diagnosed. The contact was informed that the bumper sensors and sideview mirrors where the forward collision sensors were housed needed to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was taken back to the dealer and was replaced with a similar vehicle. The contact stated that the replacement vehicle experienced similar failures. The contact stated that the vehicle was taken back to hoover Toyota where the contact was informed that the issue was due to a software failure, and that the engineers at Toyota were actively working on the software update. The vehicle was not repaired. The manufacturer was notified of the failures. The approximate failure mileage was 12.
