I took my 2017 suburban in for this problem. The service department found that the coolant pipe was chaffing on passenger side exhaust manifold causing a terrible leak. The problem was resolved, but I had to pay 639.21 for this ! This issue was caused by manufacturer installation, not driver error. I am 4, 000 miles out of warranty so therefore I paid. I enjoy Chevrolet vehicles but now hesitating on buying anymore. When a issue arises that is caused by manufacturer it should not be the burden of the consumer to pay. Chevy mistake Chevy should pay. My mistake I should pay. Simply not happy with Chevrolet.
