| Automatic Emergency Braking problems |
On this vehicle, whenever 4 low is selected, or in 4 high (normal driving mode) any off-road driving mode is chosen, a warning appears on the digital instrument cluster stating "vsc turned off pre-collision brake system unavailable". While this warning is up, no other instrument cluster functions can be accessed. Hitting the button to dismiss this warning will only make it go away for five seconds, then it will repeat and once again draw the driver's attention off the road and to the instrument cluster. It serves as a constant distraction and impediment in the most difficult driving conditions. The only way to make it not reappear every 5 seconds is to stop, go into the safety items menus, and disable pre-collision braking which then unnecessarily reduces the safety of the vehicle once it is back in a normal driving mode. This waring which repeats every five seconds must be a software bug, other similar warnings do not return once dismissed.
The automatic emergency braking is activated when no objects are in front of the car potentially resulting in being rear ended. The feature is so oversensitive that it is safer to deactivate it. Car taken to a local dealership and the concern was replicated with a dealership technician. The dealership refused to evaluate the safety concern any further as the car is being inspected by a Toyota regional technician. Additionally, the brakes squeak when in reverse but the concern has not been addressed by multiple dealerships or Toyota headquarters.
2024 Land Cruiser, purchased in July, 2024 has had 4 random hard downshifts when coming to a stop and then lunges forward as when a driver downshifts harshly in a manual car (keeping in mind that the Land Cruiser is an automatic and the driver is not intentionally down shifting). On the 4th occurance, I nearly rear ended a car. Fist occurance at approximately 250 miles and last occurance at approximately 1,200 miles. The car was taken to a local dealership on 11/04/24 but the dealership refused to further evaluate as Toyota headquarters informed them that the vehicle is sheduled to be evaluted by a Toyota regional technician. On 11/12/24, the Toyota regional technician did not replicate the safety concern per the dealership and it was advised to go pick up the car. As of 11/18, the car remains in the local dealership due to my safety concerns. Toyota headquarters has not advised me or dealership on the next steps. No warning lights on the dash are present and Toyota does not consider this a safety issue as it has not been replicated. Concern of the car automatically braking without objects in front has been brought up to Toyota as well.
