California Emission Control Warranty Statement (California Only)


Your Warranty Rights and Obligations

The California Air Resources Board (CARB) and John Deere are pleased to explain the emission control system on your new engine. In California, new heavy-duty engines must be designed, built and equipped to meet the State’s stringent anti-smog standards. John Deere must warrant the emission control system on your engine for the periods of time listed below provided there has been no abuse, neglect, or improper maintenance of your engine.

Your emissions control system includes:

  • Fuel Metering System
    • Fuel injection system
    • Air/fuel ratio feedback and control system
  • Air Induction System
    • Intake manifold
    • Turbocharger system
  • Ignition System
    • Spark plugs
    • Ignition coil and control module
    • Ignition wires
  • Miscellaneous Items used in above systems

Where a warrantable condition exists, i.e. failure due to defect in John Deere-supplied material and/or workmanship, John Deere will repair your heavy-duty engine at no cost to you including diagnosis, parts and labor.


John Deere’s Warranty Coverage

The emission control system of your heavy-duty engine is warranted for five years or 100,000 miles (160,936 kilometers) or 3000 hours of operation, whichever occurs first.


Owner’s Warranty Responsibilities

As the heavy-duty engine owner, you are responsible for the performance of the required maintenance as outlined in this Operation and Maintenance Manual. John Deere recommends that you retain all receipts covering maintenance on your heavy-duty engine, but John Deere cannot deny warranty solely for the lack of receipts or for your failure to ensure the performance of all scheduled maintenance.

However, as the heavy-duty engine owner, you should be aware that John Deere may deny you warranty coverage if your heavy-duty engine or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications.

Your engine is designed to operate on compressed natural gas only. Use of any other fuel may result in your engine no longer operating in compliance with California’s emissions requirements.

You are responsible for initiating the warranty process. The CARB suggests that you present your heavy-duty engine to the nearest John Deere engine service dealer as soon as a problem is suspected. The warranty repairs should be completed by the service dealer as expeditiously as possible, not to exceed 30 days.

If you have any questions regarding your warranty rights and responsibilities, you should contact John Deere at 1-319-292-5400, or the State of California Air Resources Board, Mobile Source Operations Division, PO Box 8001, El Monte, CA 91731-2990.

The warranty period will begin on the date the vehicle is delivered to an ultimate purchaser, or when otherwise put into service. If any emission-related part on your engine is defective, the part will be repaired or replaced by John Deere. Warranties stated in this manual refer only to emissions-related parts and components of your engine.

Any warranted part which is scheduled for replacement as required maintenance by this operation and maintenance manual is warranted by John Deere for the period of time or mileage, whichever occurs first, prior to the first scheduled replacement point for that part. If the part fails before the first scheduled replacement point, the part will be repaired or replaced under the warranty. Any such part repaired or replaced under warranty is warranted for the remainder of the period prior to the first scheduled replacement point for the part.

Repair or replacement of any warranted part under the warranty will be performed at no charge to you by a John Deere engine service dealer, except in the case of an emergency when a warranted part or engine repair station is not reasonably available to you. In an emergency, repairs may be performed at any available service establishment, or by you, using any replacement part. John Deere will reimburse you for your expenses including diagnostic charges for such emergency repair or replacement, not to exceed John Deere’s suggested retail price for all warranted parts replaced and labor charges based on John Deere’s recommended time allowance for the warranty repair and the geographically appropriate hourly labor rate. You should retain receipts and failed parts for John Deere’s disposition in order to receive compensation for such warranted repairs reimbursable due to an emergency.

Warranty service for your engine will be provided by all John Deere engine service dealers which are franchised to service John Deere engines of your type.

You will not be charged for diagnostic labor which leads to the determination that a warranted part is in fact defective, provided that such diagnostic work is performed by an authorized John Deere engine service dealer.

John Deere will be liable for damages to other vehicle components proximately caused by a failure under warranty of any warranted part.

Throughout your engine’s warranty period, John Deere will maintain a supply of warranted parts sufficient to meet the expected demand for such parts. The lack of availability of such parts or the incompleteness of repairs within 30 days from the time the engine is initially presented to the service dealer for repair, constitutes an emergency for purposes outlined above. Any replacement part may be used in the performance of any maintenance or repairs.

Any replacement part designated by John Deere may be used in warranty repairs provided without charge to you. Such use will not reduce your warranty obligations or those of John Deere, except that John Deere will not be liable for repair or replacement of any replacement part which is not a warranted part.

If your vehicle fails inspection under California’s Vehicle Inspection Program during the warranty period, you may choose to have the engine repaired by a John Deere engine service dealer at no cost to you, unless the service dealer demonstrates that part failure or malfunction was caused by abuse, neglect, unauthorized adjustment, or improper maintenance, in which case you will be responsible for all diagnostic and repair expenses. However, if failure to pass the inspection was caused by a combination of both warrantable engine defect and any cause excluded from warranty coverage, then you will not be charged for diagnostic or repair costs to correct the warrantable defect. Should your engine fail the inspection and you choose to have it repaired at other than by a John Deere engine service dealer, and a warrantable defect is found, you may deliver the engine to a John Deere engine service dealer where the defect will be corrected without charge. However, John Deere will not be responsible for costs incurred at the initial service location, except in the case of an emergency.
