The car randomly dies on DE-acceleration. It gives no warning and I have seen online this is a known issue with this year/model. I have 55,000 miles on it, it's been regularly serviced. When I got to slow down then start to accelerate it shuts off. I've nearly been hit multiple times going to merge from a stop. It's very dangerous. I've replaced all 4 spark plugs, all 4 ignition coils, air filter, cabin filter, oil filter, pcv valve and I've only owned it 6 months. No engine light comes on and no reader is picking up any codes. I'm at a loss as to what causes this.
