Grand Voyager - 4 diesel injectors fail in 80000km

Bought a Grand Voyager (top of the range) from Chrysler and within 80000km all 4 diesel injectors fail-all of this within 3 years but just out of warranty and service plan - my car has been with the service provider Cargo Edenvale now since 29 Dec 2014-quote to fix my vehicle is R40000. Such a failure is unheard of for a vehicle at such low mileage, quoting the service manager from Chrysler Edenvale. They offered to request assistance from Chrysler South Africa for cost participation or even, as a failure of all 4 injectors is so rare, to fix under warranty. Vehicle has full service record, had 72 point check done in Dec 14 and 80000km service with this dealership - a week on and all 4 injectors fail. My vehicle has been there since 29 Dec 15-phone records will show that, if I had 4 calls from them to keep me informed, it will be a lot, have to call regularly to get feedback. Chrysler SA not responding wrt assisting me to fix vehicle. Mails to Chrysler to ascertain safety and operational issues on vehicle are ignored - are my battery disconnected-standing from Dec14 and have you received the injectors back and reinstalled them.<br> <br> Great car, bad support - change brand?
