Engine light on - left cylinder head bad

Took jeep cherokee to dealer and they said the left cylinder head has to be replaced will take 3 or 4 weeks to get part then a day to repair it . 2011 jeep cherokee overland has 15,400 miles on it have had it 14 months .has anyone else had this problem, dealer told me I can drive it with light on and it will not harm engine . Is this covered under my powertrain waranty or just 36 k mile waranty. either way this sucks .so much for the wonderful articles about the engine that they showed me before I bought it. If anyone has heard anything about this please let me know . Thank you

Re: Engine light on - left cylinder head bad

Jeep claims this problem exist in only a few percent of the vehicles with the v6. No plan for a recall and handle on a case by case.

To answer your ? This would be cover under the power train warranty. 5 years/50,000.

Re: Engine light on - left cylinder head bad

so have been waiting 6 weeks for my new head to come in to dealer so they can replace it .I have an appointment on dec.4 to do it and now after a backfire in my engine the light has gone off . Does that mean they will not replace the head now because the engine light is off ? I hope they still do it it has been on for 6 weeks and they could not reset it . I hpe they do nor screw me over and say wait till it goes on again . Or after warranty runs out it has 16150 miles on it .

Re: Engine light on - left cylinder head bad

Doubt it, CJF is just fixing, back in August they estimated 7,500 heads were liable to go bad. Backfire is not good but indicative of a bad intake valve.

Once they have verified the problem and ordered the part it will be repaired. Its not going to matter if the light is on when you take it in or not. Not only that but the system saves the fault codes for a while even after the light goes out.

I find it odd that customers are waiting weeks for the part part to come in. Mine only took 4-5 days.
