Worst service ever

Bought a second hand Jeep Grand Cherokee in Jun 2014. The vehicle is a 2012 model with 80000km. I have had a problem with the automatic windscreen wiper electronics from the beginning. They 're-crimped terminals', replaced the module 2x and I still have the same problem, 1.5yrs later! I have been in and out of the service center a ridiculous amount of times. One time I actually had to drive back in the dark without headlight, as the same module controls the lights. On every occasion, Jeep has been unable to rectify the problem. Now, they have become unwilling to try and rectify it. This car has got a list price of R830K new. One would not expect to be left in the dark when paying such amounts. I have contacted head office SA many times...no response. I have recently contacted Jeep USA to complain about Jeep SA. They referred me to Jeep/Fiat Italy who in turn referred me to head office SA !!!<br> I'm sick and tired of Jeep. It is my first Jeep and I am sure it is a good product, but the backup/service stinks !!!<br> My advice to anyone considering buying a Jeep: reconsider.
