We had to have the lifters replaced, yes lifters in the engine, in a brand new off the lot 21 Tahoe 7 months after purchasing the vehicle. Now not 7 months after having a engine rebuild again on a brand new Tahoe I’m being told we have to wait 3/4 days for the truck to even be looked at AND no loaner. A brand new truck should not have to have the engine rebuilt twice in a year of ownership. I am so dissatisfied with the Tahoe brand. Has anyone else had to have a engine rebuild in a year old suv?
