I took my car in for it's 20K service on a Friday. The dealership called me to let me know the seal on my engine was off and I was leaking oil. So they took my car over the weekend and I got it back on Wednesday. I drove the car 25 miles to pick up my daughter from daycare directly from the dealership. When I was a 1/4 mile away from daycare, with my daughter in the car, my car felt like it stalled. Turns out it was on, but from there on out I couldn't go faster than 30mph. The dealership brought me a loaner. They called me today (Th)to tell me that my Throttle Body had died. Is this normal for 20K miles???
