“Rodents chewed wiring because it is soy based. I'm lucky because my car was not disabled while driving etc because the EVAP system was affected . This could have been much worse and could have caused death etc if it happened to another system of the car. ie: brakes, propulsion, headlights, air bags, etc etc etc...Cadillac dealer who fixed the issue said that it is a common problem and not warranted and my car has no warranty anyway.”

NHTSA complaint #11772069, filed 2026-10

“I took my suv in for diagnostics to a certified GM dealership at least twice while still under warranty. The check engine light was on, the car was behaving abnormally as well as making unusual concerning noises. The dealership sent me away saying no codes showed up and they couldn’t find a problem.The light would come on and off sporadically. I took screen shots of my dashboard every time the light came on. Within months of my warranty expiring xI was traveling to IL 1.5 hours from home on I-90 during heavy traffic. …”

“Recently went to my local Sewell dealership for my routine oil change. With an oil change they do a complimentary multipoint inspection. During the inspection they noticed that my camshaft carrier was leaking and needed to be resealed. The resealing of the camshaft carrier would be around $4,000. I don’t have that kind of money laying around especially in this economy. I just got a new place and I can’t Afford to spend $4,0000 right now. I did some research online and apparently this is a common issue with Cadillac cars. …”

“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?”
