I have a 2011 with 257,000 miles driving home from work one day on the highway and my battery light started flashing and my traction control button turned on, and the vehicle win in the limp mode down to about 18 mph is fast as I can go I thought maybe my transmission filter was clogged so I drop the transmission fluid changed it and put a new filter on I didn’t do the trick. I was able to drive it around some more took about 2 to 3 days before it happened again but this time it’s more severe as I start the car up and leave that battery light flashing and it is serving the RPMs are going up and down I thought maybe it was my throttlebody change that out that wasn’t the issue so I put my original one back on putting it upside down that wasn’t there so I really need help
