My Trucks Engine Died So I Purchased A New One From An Engine Reman Company. I Also Purchased The Highest Warranty Option They Had. Long Story Short What Was Supposed To Cost $3k In Labor Has Now Cost Me Over $15k In Labor Due To Them Sending Me 4 Defective Engines.

I got about 6k miles out of the first engine, looked past some issues with it that were apparent immediately since I had just dropped $5k on the engine and another $3k on labor, didn't want to go through the warranty again which only reimburses a portion of the labor and also didn't want to be without a vehicle again. After the 6k miles I'm too worried about the engine dying when I'm on a free way which would be dangerous so I bite the bullet and file a warranty claim, knowing it would cost me about $2k out of pocket even after the warranty reimbursement and would take weeks for me to have my truck back. I pay the shop their labor costs and pick up my truck. Not 200 miles later the engine starts having the same lifter issue. I go back to the shop. They eventually determine it needs a new engine. Boom, another $3k in labor that I pay for. I pick up my truck. This time it doesn't make it 100 miles and goes into "limp mode". I tow it to the shop. They do $1500 I'm diagnostics which I'm responsible for. Then guess what? Needs another engine at 3k in labor. At this point I owe the shop $7,500 in labor. The warranty company will reimburse me $2,400 (they said it takes them 4-6 months to process warranty claims). I'm at a loss on what to do. I was prepared to pay the initial portion that wasn't covered by the warranty reimbursement but for it to need multiple engines subsequently is something I can't afford. l've also been without a vehicle for 6 months as this is how long its taken to get even to this point. They're not exactly amazon prime when approving and sending out the new engines.

So far we've gone through 4 engines plus one disassemble/rebuild. $15.5k In total labor with 3k in labor to the 1st shop 12.5k in labor to this more recent shop

Warranty will reimburse 4.5k total in labor, leaving me on the hook 11k in labor.

Is my best course of action to pay the shop and then sue the engine reman company?

I'm going to investigate more to see if the shop could have made any mistakes that contributed to these issues. Wish it was as easy as defective engine, engine reman is responsible, but based on what the engine reman company is saying, the shop could have made mistakes causing these issues
