| Fuel Injector problems |
Fuel injectors clogging very often causing vehicle to run rough and shake. Dealer repaired first time with only 11,000 on vehicle. But stated that it was not warranty. Injectors are continuing to clog every 6,000-7,000 miles even when changing fuel filter and having injectors serviced. And using quality fuel and injector cleaner every 3,000 miles.
