APPENDIX B TO
PARTIAL CONSENT DECREE
MDL No. 2672 CRB (JSC)
Warranty shall cover the following parts, as further specified in the applicable Extended Emissions Warranty Parts Coverage List submitted by Settling Defendants with each Emissions Modification Proposal, as further described in subparagraph 4.3.10:
i. The entire exhaust after treatment system including the DOC, the SCR catalyst (if applicable), the dosing injector and other DEF system components (if applicable), the NOx Trap (if applicable), all sensors and actuators, and the exhaust flap;
ii. The entire fuel system, including the fuel pumps, high pressure common rail, fuel injectors, and all sensors and actuators;
iii. EGR system including the EGR valve, EGR cooler, EGR filter, all related hoses and pipes, and all sensors and actuators;
iv. The turbocharger;
v. The OBD System and any malfunctions detected by the OBD systems other than those related to the transmission; and
vi. The DPF.
3.9.2
The Extended Emissions Warranty shall cover each and every DPF that has failed as a result of implementing any Approved Emissions Modification. If Settling Defendants can demonstrate to the satisfaction of EPA/CARB in a Proposed Emissions Modification that Settling Defendants’ dealers can adequately distinguish between a DPF that has reached the maximum ash load and needs to be replaced as part of normal maintenance and a DPF that has failed as a result of implementing such Approved Emissions Modification, then the Extended Emissions Warranty applicable to such Approved Emissions Modification does not need to cover DPFs that need replacement as part of normal maintenance. I f Settling Defendants fail to make this demonstration then the Extended Emissions Warranty must cover each and every DPF.
3.9.3
The Engine Long Block warranty must cover the engine sub-assembly that consists of the assembled block, crankshaft, cylinder head, camshaft, and valve train.
3.9.4
The warranty period for the Extended Emissions Warranty shall be both:
i. For Generation 1 and 2, 10 years or 120,000 actual miles whichever comes first; for Generation 3, 10 years or 150,000 actual miles whichever comes first; and
ii. 4 years or 48,000 miles, whichever comes first, from date and mileage of implementing the Emissions Modification, except for vehicles offered for resale, in which case, from the date and mileage of the first resale transaction after the modification to the first person who in good faith purchases the vehicle for purposes other than resale.
I'd love to do the fix... but in that case we only get $5000 and one screw up after the short 18k mile warranty will wipe that out.
