I purchased a '07 4runner with 55k mi on it yesterday. the wife drove it home (1.5hrs), and we then took it out when we went to dinner last night. I noticed the temp gauge fluctuated quite a bit, more than i felt an 07 vehicle should. i checked the coolant level this morning and it was low so i went directly to napa and topped it off. Then i went to lowes and the temp gauge shot right into the red. shut it down and let it cool off. Got it cool enough to where i could drive it home (1mi or so) and changed out the t-stat on it. T-stat fixed the issue as far as i can tell, drove it around for 45mins or so and the gauge was perfectly centered the whole time.
I didn't get it inspected by an independent mechanic, i bought it from a reputable nissan dealer who said they do a 100+ point inspection when they take a car in on trade and found no issues. I bought it as-is, no warranty.
Should i contact the dealer and complain? What are the chances there are other things that were over looked, or did the t-stat just die like that?
really they hold no responsibility since i bought it as-is, but i didn't know if there was something else i should do in-case.
pretty pissed, pretty bummed. i'm supposed to enjoy a new car purchase, not worry.
