Hey everyone, longtime reader, first-time interacting. Appreciate everyone's comments and suggestions over the years, which significantly helped my decision to buy a certified used 2014 CMax energi. Love the car so far, averaging 55mph over the 16,000 miles driven so far, and am excited about it.
Lately, though, I've been having issues with the warning light (yellow wrench) and once with the red triangle (safely pull over). The first few times with the yellow wrench occurred after preconditioning the car while plugged into an 120V outlet; however, these lights went away upon the subsequent restart (once on Jan. 8 and one on Jan. 9, but none after that). Then, on Feb. 22, the car had the yellow wrench and red triangle, and, ultimately, I had to push it to the side of the road and have it towed to the dealer. It spent 9 days at the dealer getting diagnosed and, finally, the repair was to replace the high voltage coolant pump (I think). Thankfully, most of this was covered under warranty.
Fast forward a few days, I'm driving on EV only mode and the yellow wrench reappears and the car switches into regular hybrid mode (gas and electric). However, the light went off and didn't return upon restart. Has anyone else had issues with the high voltage system, particularly in cooler climates?
Any and all information would be helpful. I may take it to the dealer on Monday just to have it re-examined, especially because of the recent work having been done on the car. I really love this car, but I don't want it to have these issues.
