My oil cooler was replaced by the dealer under the 100,000 mile warranty. Lasted 8 months, blew up again.
I have a lemon lawyer looking into all this stuff that has happened to mine.
2 radiators (no help from warranty on either)
2 oil coolers ruptured or what ever in the heck happens to them.
Turbo going bad because of the dealer who fixed the first oil cooler forgot to tighten the oil line to the turbo (but would not fix it. Charged me $2300.00 to fix it.)
Had to replace the front motor cover.
Had to replace the front crankshaft seal.
I have not had this much trouble with all the vehicles combined in my 58 years of owning and driving vehicles, most of which have been Chevrolet.
I have never really seen a "Lemon" but if this one does not fit the qualifications of one, I think maybe there is no such thing as a "Lemon".
We have actually been afraid to drive it out of sight of the house.
