 I had a lot of problems with this car after buying it from Carmax, mostly because of the original build on the transmission. I was stuck holding most of the bill for botched warranty repairs. I had the car for only 9 months and had to get the entire transmission harness replaced because someone at a certified Ford repair facility shoved the plug in and wrecked it. The stutter was another thing I should have immediately noticed but it didn't always happen. I had issues with the battery three times which affected the Transmission Control Module and I was left with a semi repaired vehicle, a bill, a handful of excuses. By some divine providence we are out of it after two years. So glad i had GAP on that thing, but thanks to this car I am still under a mountain of debt.
