Back in April of 2024 when the truck only had about 16,500 miles on it the engine went out causing steering to become heavy and braking to become very hard. This happened on a highway going about 65-70mph. The should was very narrow causing the truck to kind of protrude into the roadway, almost got hit by several cars, trucks with trailer going by. Called the on star folks and they were very poor to respond quickly, they had the police come, however there was an accident that happened further up and he left to tend to that accident. The engine ended up having to be replaced and that took a very long time. Now I have 22k miles on the truck and have had nothing but constant issues with the air ride suspension. I have taken it to two separate Cadillac dealerships and neither fixed the issue, they said they fixed the issue but I keep having the issue. Now, what the truck is doing is basically and randomly going from over inflation to under inflation. When it over inflates the truck feels too heavy and like it wants to topple on the highway-??so I have to slow way down. When the truck under inflates the ride becomes unbearably rough. This all happens randomly with no input from me while driving, a message simply pops up on the screen saying service leveling system vehicle either too high or too low. I now have taken the truck to a Chevrolet dealership to see if they can-??t resolve the issue.
