The vehicle was stalling multiple times on the freeway on my way to work this morning (9/25/19) and there is a sudden thump on the engine as it was trying to accelerate and would stall again after a few yards. so i decided to pullover safely and started the vehicle again until i reached my destination but with emergency lights on. this is absolutely a safety issue as it increases the risk of a crash or being hit from behind, with the vehicle stalling. this is the 2nd nissan quest i owned and it is having the same problem. the 1st one had issues at 50,000+ miles. the manufacture should look into this safety issue.
