What is the factory powertrain warranty on my 2008 GXP? I have only 44k miles on her and shes ticking during cold starts.

So the tick goes away when it's warm? If so, it's most likely lifter tick and is quite normal. What weight motor oil are you using?

This PI was superseded to revise repair instructions to include replacing the oil pump and pick-up tube o-ring. Please discard PIP4499.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:

Some customers may comment on a short duration lifter tick noise that occurs after cold start and can last for several minutes. This may be the result of air in the high pressure chamber of the lifter affecting valve train lash. When this occurs, valve closing velocity is increased, which causes the noise. Air can be present in the lifter at shutdown due to an aerated oil condition, or it can be ingested into the lifter during a cold start from a suction side leak at the oil pump or oil pump pick up tube o-ring. Oil aeration level, oil viscosity, time to achieve oil pressure, engine speed, and lifter design all play a part in whether lifter noise is observed. Once air gets into the high pressure chamber, it will slowly be expelled through the very tight clearance of the plunger and body.

Recommendation/Instructions:

If the SI diagnostics do not isolate the cause of this concern, perform a cylinder power balance test with the Tech 2 while listening to the noise.
If the noise is eliminated, or is greatly improved, each time a specific fuel injector is cancelled, there is most likely a concern with the clearance of the related piston pin or piston to cylinder wall of that cylinder.
If there is no change in the noise when canceling the fuel injectors with the Tech 2 and this noise occurs at valve speed, the noise is most likely a result of air in the lifters as described above. The air may be the result of a suction side leak at the oil pump and/or pick up tube o-ring, or it may be the result of the lifter design.
If this concern is encountered, replace the oil pump and pick up tube o-ring and re-evaluate the noise. If this does not repair the noise, updated lifters will most likely repair the noise but they will not be available until the 4th quarter of 2009. This P.I. will be updated with additional information as soon as they are available. Replacing the lifters with the ones currently in GMSPO stock may not repair the noise.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Nice find Derek. Didn't know there was a bulletin out about those engines regarding this.

I honestly don't remember what the warranty is exactly, but I think its 5yrs/100K miles, which means that you're probably still covered if your car is a 2008 with 44K miles. We bought a GM car in Feb 2006, and they upped the warranty right after that (from what was 3yr/36K......yes I was ticked).

Basic New Car Warranty is 3/36
Drivetrain/Powertrain Warranty is 5/100

Seeing as it looks like an issue with internal engine components, it would be under the 5/100 Powertrain Warranty.

Things with dealerships though.. (This is the way Acura and Subaru work, my employer)
Firstly you gotta make an appointment to get your vehicle looked at, and make sure you schedule it as a wait (unlikely), drop-off, shuttle or service loaner..

They'll likely tell you they'll have to perform a diagnostic first to verify it's a warranty issue covered under the Powertrain/Drivetrain warranty.

Likely they'll quote you some diagnostic time before hand just in case if they do a diagnostic and it was found not to be covered under warranty, they'd need to get paid somehow (the technician for his/her time), and the diagnostic charge is going to have to come out of your pocket.. But at least you now know what's going on with your vehicle. At that point you can either decide to go ahead with said repairs, or shop around and weigh your options.

If it is found to be covered under warranty, then Pontiac/GM is going go pay for the diagnostic charge, as well as any repair costs to your vehicle in regards to the internal failure of powertrain components. At this point you can either continue on with the warranty work, or schedule another time to bring your vehicle in to continue warranty work if it takes longer than you've allocated for the service visit. In most cases the dealership would be able to shuttle you to and from work/home or wherever.. or if you've scheduled a loaner vehicle with your appointment, you'd stay in the loaner from the point where you got checked-in and dropped off your Pontiac, 'til repairs to your vehicle is done. Then you'd usually have to bring the loaner back the same day as your vehicle is done.
