While on the freeway, going approximately 70 mph, the vehicles onboard cameras all failed and I got a warning that said camera dirty/unavailable/traffic sign assist currently unavailable. Because of this failure, I almost crashed the car in Front of me. I cleaned all the cameras. The message continues to appear. The dealer said its a known malfunction with this particular model, based on the chip shortage, during Covid. My car has 57000 miles and apparently several owners of this model, are experiencing the same issue. Dealer wants to charge $1,800.00 to fix a vehicle safety feature, that shouldnt fail this soon.
