Hate Dealers

[Hopper]

My daughter saved up and was ready to get out of my TJ and buy her own Jk. We found a good one. 2018 clean carfax with 74,000 miles. Certified pre owned at Dodge Chrysler Jeep with bumber to bumper waranty 3000miles or 3 months. I told her I would purchase an extended warranty 3yr/36000 drivetrain since I was so proud of her saving and cashing out on her Jeep. One day after purchase check engine pops up. Code P0128 low coolant temp. Dropped it off at the dealer to fix. They call me back and say it was the battery so we gave you a one. I laughed and said thats weird, I thought it was low coolant temp code. He mumbled a bit and said this is what the tech found, said the thermostat was opening and shutting fine so just the battery. Picked up, skeptical as all get out, and of course next day check engine light. A part of me wants to change the thermostat and burp the system but a big part of me wants them to honor ther Damn warranty. So I'm taking it back.
Rant over for know.

Had the same issue few years back. The t-stat is likely stuck open and the coolant is flowing at start-up, not allowing the engine to reach normal operating temp.

Let us know how long it takes the dealer to figure it out.

I hear you. That was the 1st thing I brought up to them. We will be having a longer talk tomorrow when I drop it off although they dont listen cause you know I'm not a master mechanic and all.
