It sounds like impossible but it happened. I went to dealership today just for regular oil change. After 20km, it stalled when approaching a stop sign. I saw CEL, engine oil light, battery light, etc. but had no time to take a picture. I restarted the car and it runs fine and has no CEL. It has 3.5L V6. This never happened for 100,000km within 8 years. I will go back to the dealership tomorrow. What can go wrong during an oil change? Is this just coincidence? Thanks.
