Lehmann-Peterson is a certified Cadillac Master Coachbuilder (CMC). Therefore, Cadillac's 3 year/150,000 mile warranty is preserved in your XTS-L Long Door Sedan. Cadillac's Professional Vehicle Protection Plan (PVPP) provides the terms which preserve their warranty for modifications required by for chauffeured transportation and funeral industries. PVPP is an extended service agreement for Cadillac Professional Vehicles and runs concurrently with the Cadillac Bumper-to-Bumper New Vehicle Limited Warranty.

Furthermore, the Lehmann-Peterson warranty is guaranteed to cover repairs or correct malfunctions, which occur during the warranty period for any defect in material or workmanship on the vehicle conversion.

Base Chassis Manufacturers Warranty: The Original Equipment Manufacturer’s warranty remains in effect after the conversion and sale of the vehicle. Upon resale, the base chassis warranty (which was delayed during the conversion process) must be activated to validate the owner’s warranty. Warranty claims, which pertain to the base vehicle, and not to the Lehmann-Peterson conversion, may be handled through an authorized dealer representing the OEM manufacturer.

Upon the sale of the vehicle, a Notification of Delayed Delivery form, which accompanies the title work, must be completed and forwarded to the Warranty Department at Lehmann-Peterson. The filing of this form will validate the Delayed Chassis Warranty from the OEM.

Lehmann-Peterson modifies vehicles that are manufactured by others. The warranties we offer do not, therefore, extend to or cover any portion of the original equipment or the contents thereof that are separately warranted by the original equipment manufacturer.

Lehmann-Peterson’s warranty is available to all dealers. All warranty work, whether handled by an OEM or independent dealer, are  pre-approved by Lehmann-Peterson before conversion/modification work on your Cadillac XTS commences.

How to submit a warranty claim:

Dealers must call the warranty department at (847) 202-0080 for authorization.

  • Date of vehicle purchase
