My Grand Jeep Cherokee

Im 2015 i purchased a brand new 3.0L CRD Grand Cherokee. In the 3 years i owned the vehicle it has picked up numerous electrical problems and keeps going back to the dealership. Everytime i give the van to the dealer it sits there for 2-3 weeks. My vehicle only has 37000 km on the clock. It spends more time at the dealership than with me. Now the vehicle cuts off while im driving and the engine light comes on along with other warning lights. Its been towed to the dealer 4 times in the past 4 months. Everytime the van brakes down it endagers me and my family. The highest of managers got involved and theres still no progress in this problem. Jeep has not once offered me a courtesy car nor have they given us a job card stating problem and what they have done to resolve it. The van is at the dealer at hthis moment. They called yesterday to notify me that the van is ready but they called today to tell me that the engine light came on again. So once again nothing is getting done. Thiss issue has brought a great discomfort to me when it comes to my long distance travelling. I wanted to trade the van in but i dont want someone else to suffer with this problem. This is why im on hellopeter...
