I am having an issue, and I was wondering if anyone has a solution or knows what I should do next. It is now going on for several months, and my dealer, who seems to be trying, hasn't found the fix--so far.
Driving along, the check engine light goes on in steady yellow. Other than the light coming on and remaining on, the only other thing that tips me off to something being not right with my CMAX is that the fuel economy is not as good as it usually is.
I run a Vehicle Health Report. The report indicates that it is emissions related. I bring it to the dealer. They say that it is a sensor. They order and install the sensor. I am driving home from the dealer, and the light comes back on.
I run another Vehicle Health Report. Same issue. I go back to the dealer. This time they tell me that the trouble is that the fuel filler is allowing air to leak in, and they have to replace it. They order the part and install it.
I drive home, about 45 minutes or so away from the dealer, and I park in my garage. In a couple of days, I have to run some errands. I get in, pull out of the garage, and the check engine light comes back on again. I run another Vehicle Health Report, and it still shows the same issue.
Any hints about what this could be and what to do next? I have an extended warranty to cover this, and I bought it through my dealer.
Other than this, my 2013 SEL now has about 34,000 miles on it, a lifetime MPG of just under 48 (it was above 48, but then I drove around for the past couple of months with the issue, and now it has dropped), and it has been a dependable car. The back and forth to the dealer, and rental cars, is getting tiresome, and I would really like for this to get fixed on the next attempt.
