2019 Cadillac XT4 Engine Problems

I took my car is for service at the Cadillac dealership and they stated there was an oil leak from the camshaft carrier. When I asked more questions they stated it was a fairly common problem with the XT4 and a few other models where there was a faulty seal at the "T-joint" (cam carrier T-joint). My car is no longer under warranty, but had under 26000 miles at the time. There were no warnings or symptoms. I would not have not if the dealer had not told me. The cost was estimated at $3254.45. If this is a common problem, why isn't there a recall?

During oil change Cadillac mechanic noted camshaft oil seal leak. Video was provided. Mileage on car is 51,534 at that time. I feel that this is too premature and repair requires pulling the engine. Very expensive. Quote was $4,597

At around 17,000 miles the timing chain tensioner went bad. At cold start up you could hear the timing chain hitting the 'guide' until the oil pressure built up and provided enough tension. I was covered by an aftermarket warranty - which paid all the labor ($1700). I had to pay a $100 deductible -along for the parts ($300). I feel that this should be looked into and Cadillac should replace any tensioner that might be defective- since this could cause catastrophic engine failure. If you check - it does appear the 'new tensioner' part number is a revision- indicating Cadillac probably knows the old part number was defective!

The engine started to leak oil, coming down the passenger side of the motor. This was around at 22,000 miles. The dealer says that this is a leaking intake manifold gasket. It has taken them 3 separate repairs to fix this issue. I feel that my engine warranty from Cadillac should be extended, past the 5yr 60k powertrain warranty. We have had this vehicle now for 4 years, and we don't drive it alot. As of this writing 11/21/2023 the vehicle has around 29,000 miles on it. It appears that it is leaking again, so it will be going back into the dealer again.
