Jeep Patriot - Problematic since purchase!!!

I purchased my dream car, Jeep Patriot Ltd Edition, in 2009. A year later, sub-sequent to the annual service, I experienced a problem with the 4X4/ABS light/alarm staying on continuously. I booked it in for a diagnostic test and was informed that one of the sensors need to be replaced. This problem persisted for the next 3 years and the outcome was the same (sensor replaced) even though I expressed my concern that the problem MUST be far more serious. Eventually, after my maintenance plan ended in 2014 and the problem persisted, I was told that the ABS pump was cracked. To add insult to injury I was asked to pay for the test to diagnose a problem that I was trying to highlight for 4-5 years. I am extremely disappointed with the service from Chrysler Jeep Dodge Umhlanga, South Africa and would NEVER, NEVER purchase another JEEP and neither would any of my family or friends!!!
