Reoccurring Problem and no solution from McCarthy CJD Centurion

I Just need to share this, I've had my Jeep Renegade Trailhawk at Bidvest McCarthy CJD Centurion at least 6 Times this year. The check engine light comes on sometimes goes off by itself. I've left the car there 3 overnights. Guess what the light came on again Yesterday 3000km after I had the car there the last time.

Oh and as a side note - if the check engine light comes on the 4 wheel drive system does not engage - left me stranded in Lesotho on my way to Katse Dam in July. Last time it happened when I asked my service consultant why the light came on she could not tell me - Just looked at me.

It's now at 63 000 km and the service/maintenance plan ends in December. I'm not looking forward to paying for these frequent visits out of my own pocket next year.

I'm very disappointed, and not looking forward to another visit maybe being without a car again this week.
