EyeSight and driver-assist dropoutsmoderate
The second real thread. Owners report the whole driver-assist suite shutting down together — 'All the advanced driver assistance system items listed on the website list all shutdown. The emergency brake lamp also was lighted' — with the fault clearing and returning within a day and the dealer unable to solve it. Others report the opposite failure: the car braking hard on its own with nothing in front of it, once into low sun at 35 mph. One owner reports a dealer running seven failed EyeSight recalibration sequences and releasing the car anyway. And one complaint traces a total loss of EyeSight, all-wheel drive and power-steering assist to a blocked air-conditioning drain soaking the electronics under the front seats. Two things to do: exercise adaptive cruise and lane centring properly on the test drive, and check the carpets under the front seats for damp, which is a cheap fix that prevents an expensive one.
