While driving the car will randomly rev very high it started about 3 weeka ago while driving at around an average of 45mph in city. It was initially just revving 3-4 times until I hit the break and it was isolated to one incident per drive. But last night after driving on I-25 at highway speed I turned to a slower busy street more stop and go traffic and the car started revving again only this time it did not stop after one incident. As soon as I hit the accelerator it went into a revving fit. And didnt stop I couldn't even drive it because I could not get it to accelerate. I tried turning off blue drive and tried shifting down to 1st gear so I could at least make it at 10-15mph but it revved up even in manual gear. I had to park it for the night in a pretty sketchy neighborhood and call an uber. The system didn't populate any codes and no service lights came on. Then, this morning when I went back to get the car to a mechanic and it was accelerating fine though it was sluggish. I managed to make it 2.5 miles to a mechanic without incident but still no service engine light.

The problem occurred at a stoplight midway through my trip home from out of state. The car started "chugging" like it was not getting gas and hesitated. Soon after the check engine light came on and we had to exit the highway and pull off to get it checked. The auto parts store code reader came up with a fuel pump or fuel filter problem. We were directed to the closest auto repair shop as our car was unsafe to keep driving. We had to purchase a new high pressure fuel filter for our car. $577 for part, total bill $734. The dealership says this is only covered for 5 years/60 miles. My kids is 5 years/3 months and 93000 miles. The dealership and shop state they are repairing more and more of these. I feel this part should be recalled and I should be reimbursed for the repair.
