Although you are required to perform every Manufacturer’s Recommended Maintenance with your selling dealer or a facility which has been preauthorized, you may call us at 1-866-494-1366 and PRE-AUTHORIZE any maintenance service to be performed while you are traveling or not at the selling dealer.

You may call us at 1-866-494-1366 for assistance or you may contact your selling dealer’s service department for details.

Towing and rental car coverage is not provided by your Lifetime Warranty Program contract. However, if you purchased an extended service contract, your extended service contract will most likely provide that coverage for you.
Any repair facility or dealership that employs ASE (Automotive Service Excellence) technicians. ASE technicians are certified through a national non-profit organization to ensure the technicians competency in many areas of the automotive industry. Repair establishments with at least one ASE technician are permitted to display the ASE sign. Motorists should look for facilities that display the ASE Blue Seal of Excellence logo.
One of the advantages to taking your vehicle to a licensed repair facility is that if an ASE certified technician is not the individual working on your vehicle (say, for an oil change), they are still available to assist and oversee the work being performed. This ensures that the maintenance is being performed properly, and to the manufacturer’s recommended specification.
No, not exactly. As mentioned earlier, the technicians themselves obtain these certifications. The facility itself is not certified, however, businesses with a high level of commitment to ASE (75 percent of service personnel certified) are entitled to a special “Blue Seal of Excellence” recognition from ASE. You will sometimes see this logo displayed inside the facility waiting area.
