Wiring problems of the 2016 Chevrolet Traverse

Side detection system and cross traffic warning systems failed at 58200 miles on 2016 Traverse ltz. Warning messages appeared on dic to have this issue serviced. The messages appeared upon startup and while driving. Dealer indicted detection modules and wiring harness must be replaced due to water intrusion and corrosion in the module wiring connection. He indicated this was a well known gm issue. Repair cost is $1350. 00 and not covered by warranty. He indicated some earlier models have been reimbursed for repair but so far the 2016 Traverse is not on the list. This is an important optional safety feature that gm needs to resolve across the product offering. The design is poor with the module mounted inside the rear bumper cover subject to road salt, water and debris and a poorly sealed wiring connection.
