I am a new member to this forum and I am not wure whether the same issue has been discussed (I could not find the exact issue). I just bought a new CX5 GT and now the mileage is only 400 miles. During these mileage I experienced 4 times already a situation where the engine all of the sudden stalls (engine top with engine indicator on). All the incident happened when I drove slowly (bad traffic) with I-stop on. Two incident were in the curb when I have to turn and push the brake. The engine stalled when I want to accelerate by pushing the pedal. Two incident were in the straight road when I have to slow the car (5-10 Km/hr) and the engine stopped when the accelerator were pushed. I have reported to the dealer and the said they do not have the situation before. I just noticed today in my last incident, the I-stop did not work since the last engine starts (I did not switch it off). I want to share it if there is a similar situation happened to help the local dealer fix it. Sorry for the long explanation.
