Error codes and lots of B.S.

C0327 - The transfer case shift control module reads back a high voltage when a low voltage is expected, or low voltage when a high voltage is expected on the encoder channel circuits, or the encoder signal return circuit.

C0326 - The transfer case selected range has been reported as invalid by the transmission control module (TCM). Or, rear differential status has been reported as locked by the TCM when the vehicle speed is greater than 50 km/h (31 mph) for 10 seconds

The keywords (4493, 4494 and PIP3701) are noted in a PI where engineering is asking for more information from the dealerships on what they find when performing certain procedures. This information is needed since engineering is trying to figure out why the problem is happening. It doesn't say, but it might be that a particular part is being replaced, yet engineering is testing that part and finding nothing wrong. Therefore, the actual repair might be accidental due to something as simple as seating the connector correctly upon replacement of the part. (Connector not installed correctly, tech replaces part, and now connects the connector properly. Customer does not come back, tech believes the replacement of the part fixed the condition, but engineering can't find a fault with the part when returned for testing.)

I'll be curious, I got the stab/traction control failed yesterday when starting my vehicle. Made an appointment with the dealer for this morning. We talked a bit, and from his experience the usual cause is the encoder motor; something I have also heard, as well as a TCCM replacement or reprogram.

If engineering gets enough information from the dealers, they can then duplicate the problem, and at that time work toward a fix. If a connector problem, talk to the plant to make sure they seat the connector correctly. If a part problem, work with the supplier to fix the problems.

I guess it falls under the category of "sh*t happens." Believe me, I don't like the idea of getting up an hour earlier than usual to take the vehicle into the dealer. But I do know that first year vehicles tend to have more problems, and all man-made machines break. I will say for a first year vehicle, so far, mine has been great.

As for the cracked upper rails, that is a known problem and being hotly discussed in the General H3 forum. The fix is coming, but not until May when new designed parts will be released. At least the crack is hard to see, and there is no problem from this crack, other than looks. Water intrusion is not a concern. do recommend waiting until the new designed rails are released. No use having the tech replace the rails with new rails that may crack again. This causes more stress on the fasteners in the roof. In addition, at the time of the new rails, there will be new A-Pillar molding released that have a better fit to the upper rail.

Pulley squealing is a known problem, primarily with early vehicles (I'll have mine fixed when at the dealer, been putting it off for many months). Power window failure, that is a new one, and hopefully just a fluke. (It was a very common problem with C5 Vettes, though.)

Clunking of gears, first I heard of this, that is unless he is talking about when you are engaging 4-Low or the locking rear axle. When engaging 4-Low or the locking axle, a clunk is quite normal.

Hope they get your vehicle repaired.

So is it really noisy in the morning when cold? Mine does this but only for about a 1/4 mile, then its quiet.

Dealer tried to duplicate, overnighter, but it was too warm out. Sewie and Rox both heard it one morning in Reno, about 34 degrees out.

Same thing?

See if the crankshaft pulley looks like it has an orangish tint to it. I have seen them have coolant residue on them causing a squeak. I think you've had your vehicle for a while though and usually this is on pretty new vehicles. Also make sure the powersteering pump pulley is flush with the shaft. Other than that it could be just a bad belt or a tensioner or idler pulley.

Thank you!
