So guys im officially at 139,000 kms and my GMPP plus is over at 140,000. I went to the dealership today and took the bullet. I need warranty on this car.
So I bought 2 years 40,000 kms Max I can get, powertrain. It costed me $2014 CDN. He quoted me 2600. I negotiated and saved $600
Anyhow rear diffs and alot more stuff is covered for 2 yrs now
Here is a list
Engine Gasoline/Diesel
Cylinder block, heads, all internally lubricated parts; manifolds; timing gears, timing chain/belt, timing cover; flywheel; oil pump/oil pump housing; water pump; fuel pump; fuel level sensor; harmonic balancer; OHC carriers; valve covers; oil pan; engine mount; seals and gaskets. Also covered are turbocharger/supercharger housings, internal parts, valves, intercooler, seals and gaskets, diesel fuel pump, lines, nozzles and vacuum pump.
Transmission/Transaxle
Case, all internal parts; torque converter; transfer case; vacuum modulator; transmission mounts; seals and gaskets.
Front/Rear Wheel Drive Assembly
Final drive housing, all internal parts; axle shafts and axle shaft bearings; constant velocity joints; axle housing, all internal parts; propeller shafts; universal joints; wheel bearings; locking hubs; front differential actuator; supports; front hub bearings and rear axle hub bearings; seals and gaskets.
If you have a choice get it. My one rear diff would have costed me $5000 if I didnt have warranty.
Btw I have mods from headers to anything you can imagine except maggie and my dealership doesnt care.
GoodLuck!
Extended my Warranty at 139,000 Kms
