DO NOT BUY JEEP - BEWARE

I bought a Jeep Renegade Trailhawk 2.4 L end 2015. It has now done just under 30000 km. A few weeks ago I got the check engine light and the 4WD disconnected. Took it to Rola Jeep in Somerset West. They said it needed a software update according to the diagnostic machine. Software was updated - Jeep was with them for 4 days. The next time I drove it - light on again - took back to Rola. Three weeks later they me I must replace the diff at cost of R25.5K! No guarantee this will solve the engine light problem. Jeep SA managed to get that price down to about R20K and still no guarantee that it will solve the problem. Hows that for wonderful service and a wonderful product?
