Hey all,
I have a 2015 CT200h FSport that has about 43K miles on it. I bought it back in November used and I was getting great fuel economy in eco mode, averaging 44 with a mix of city and highway driving. In early January I loaded my car up with lots of stuff and drove about 100 miles that day with all those items in my car. Since then, I've had decreasing fuel economy. Right after that trip, I noticed my average was barely 37mpg, with similar driving to what I was doing before. The next week, I was down to 35, the next 33.
As of now I am still averaging about 34. I also notice a lack of overall power and the electric motor seems to be hardly used anymore. I notice that the car switches to full gas power at much lower speeds regardless of how I accelerate. I've been monitoring my battery levels throughout all this and they look perfectly normal, never dipping below 3/4 full.
In the past few days I've been driving in sport mode, and the car has been using the electric motor much more now, actually inproving my economy to about 35mpg. Not sure what this really means but I'm going to continue this for now.
I've read online that something like a dirty oxygen sensor, dirty fuel injectors, or bad spark plugs can be the cause. I'm going for an oil change this week as well just to rule that out. My tires are still good and are properly inflated, and I don't have a stuck brake caliper.
This huge drop in mpg is very odd to me and I was wondering if there is something I'm missing that would cause all this. Particularly the large drop in the electric motor's usage in eco mode. Anyone have any ideas?
