I bought a CPO 2 months ago. It is a every early build 2019 FE with 4600 miles. It is never titled so qualify for $7500 tax credit. I took a chance as it has everything I wanted and it is hard to pass 33k off the list. At time I had a deposit on Tasla Y and got a $50000 trade in offer for the I pace. So in the worse case, I figure I can trade it for a Y without lose any money with $7500 tax credit. So far I had 1200 miles on it and no issues. The problem is now it is hard for me to consider Y after driving the I pace, even if it give me some problems. So far so good.I would safely guess there are way more early build cars without problems then there are with problems. I have not seen anything that would demonstrate the build date has impacted reliability.
If the car had been titled, then I would be reluctant. But if they are selling as a previously untitled car, it would qualify for the $7500 tax credit. So if you can get it $30k off MSRP + the tax credit. Holy ** that is a ** of a deal. I would consider buying another one at that price!
Honestly you are well protected as far as defects from a warranty & Lemon Law perspective and at that price point you are not going to lose excessive value on the car.
I would insist they put it on Pathfinder and update ALL software, not just the 3 the consumer can see.
Maybe see if you can spend a weekend with it before plunking down the cash?
