#74 of 79 H3 Hummer Cylinder Head and misfire by gloria1960

My 2008 H3 at 42k miles is at GM dealership. Running rough at idle but Onstar diagnostic did not catch when I asked them to check engine. Now dealership says its the cylinder head and replaced it under warranty. Also said to do the oil change, clean throttle and fuel injector for a total of $350. Anyone else having cylinder head issues? Should they have included the "cleaning" under warranty when they replaced cylinder head?? I'm a girl that knows Nothing about trucks but after a week in service they didn't know what was wrong and I "googled" and found lots of other people having same issue...duh, why didn't dealership know this immediately? Not real confident in the service department at Tustin GMC

These are good questions, Gloria1960,
 
Warranty coverage on the 2008 H3, as your service department states, does indeed cover the cylinder head. However, the fuel injector does not fall under the warranty, nor does maintenance. If you would like for us to assist you in working with the dealership, we would be happy to do so. Please email us more information, including your name, the last 8 digits of your H3's VIN, and the name of your dealership.
 
Regards,
Sarah
GM Customer Service

Sarah,
 
I guess I look at this very much like a garbage disposal. If the disposal (cylinder head) is properly working then the line (fuel injector) would not be clogged or need cleaning. I understand maintenance is not covered however, due to the fact the "cylinder head" was not working properly then the throttle & fuel injector may not need to be cleaned either. I've already spoken to someone at GM Customer Service and she is assisting me. Thanks. As a member of "GM Family" (6 siblings work for GMC in Michigan) I just think if a part is not working properly and has to be replaced....cleaning the lines that connect the part to the engine should be "cleaned" as part of the process of replacing a part that is irregular.

I guess vibrations can be like shocks. The head is good, the motor mounts were not so. Got a new thermostat. Like having a gm extended warranty thru most of next year. Always looking though. Hoping a new trailblazer is true to its name and under 200" in length. Unlike most people around here, ours get the garage.
 
Considered a new grand cherokee especially after Motorweek reported no trips to the dealer. Was on the table after reading the story about the great engineering team for Fiat getting the eight speed working. Then learned about all the transmission plants clustered in Indiana. And read the truck plant unrest over quality. Remembered the seventeen hour assembly time for a jeep. Remembered GM Lordstown and line speed. Then saw the grand cherokee getting the new nine speed. Is the same man in charge of the nine speed - don't know. Don't want direct injection. Save diesel for the trucks who need it. Would take a supercharger over a turbo anyday. Yeah, keep Blue Beauty.
