Purchased a used 2018 Corvette on 5/28 from a Cadillac dealer in Cincinnati. Car has 13,500 miles on it. On 5/29 the engine developed a common lifter chirp issue. I drove the car 75 miles total including the drive home from the dealer on the previous night. Contacted the dealer to inform them of the issue immediately. On 5/30 in the late afternoon the car was picked up on a roll back to avoid further damage. The selling dealer originally arranged for the car to be taken to a Chevrolet dealer that is certified and experienced with Corvettes. I was later informed that the Chevrolet dealer declined to take the car for various reasons so the car was taken to the selling Cadillac dealer for the repairs. On 6/4 I was contacted by the service manager who explained that it may take a while for the repairs because of process issues due to them being a Cadillac dealer and a large warranty issue. The car was assigned to the shop foreman that obviously has other job duties, however he is the most experienced. One 6/7 I left a message for a status on the car. Got a response on 6/10 it is in fact a lifter failure with damage to the cam and the cam, lifter and push rod will be replaced but I was cautioned that the parts may be difficult to obtain. However is all covered under warranty (which I expected). On 6/17 I received a voicemail that a portion of the parts are on back order and expected to be available in 4-6 weeks. On 6/18 I called the dealer to escalate the issue and expressed concern that at this rate the temporary tag would be expired, payments would be made and parts must be available at other dealers or able to be sourced from outside vendors. the called me back 10 minutes later stating they may have found the head gaskets (the only back ordered part) at a dealer in Indiana and would call me back tomorrow.
I am frankly just frustrated with the entire scenario. I completely understand part failures. I understand things take time. But I should not have to keep pushing for a quicker solution. Dealers shouldn't disagree on who should work on the car and the car should have gone to the most qualified dealer. I wasn't provided a loaner to drive for a car I just paid 50k+ for that immediately had a defective warrantied part. The down payment cleared faster than the first update on the car. The tag will likely expire before I have it back. The car is new to me, i didn't even have time to reset the radio stations. Now I have a car that has had the engine dissembled. I am just plain frustrated with no real clear action.
I have a 2015 Cadillac Escalade, 2011 GMC 2500HD Denali crew cab for which I purchased new, and multiple GM classic cars. I am a loyal GM owner but this experience doesn't make it easy.
