OVERVIEW 

The Motorist Assurance Program is the consumer outreach effort of the Automotive Maintenance and Repair 
Association, Inc. (AMRA). Participation in the Motorist Assurance Program is drawn from retailers, suppliers, 
independent repair facilities, vehicle manufacturers and industry associations.  

Our organization's mission is to strengthen the relationship between the consumer and the auto repair industry. 
We produce materials that give motorists the information and encouragement to take greater responsibility for 
their vehicles through proper, manufacturer-recommended, maintenance. We encourage participating service 
and repair shops (including franchisees and dealers) to adopt (1) a Pledge of Assurance to their Customers and 
(2) the Motorist Assurance Program Standards of Service. All participating service providers have agreed to 
subscribe to this Pledge and to adhere to the promulgated Standards of Service demonstrating to their customers 
that they are serious about customer satisfaction.  

These Standards of Service require that an inspection of the vehicle's (problem) system be made and the results 
communicated to the customer according to industry standards. Given that the industry did not have such 
standards, the Motorist Assurance Program successfully promulgated industry inspection communication 
standards in 1994-95 for the following systems: Exhaust, Brakes, ABS, Steering and Suspension, Engine 
Maintenance and Performance, HVAC, Electrical Systems, and Drive Train and Transmissions. Further, 
revisions to all of these inspection communication standards are continually re-published. Participating shops 
utilize these Uniform Inspection & Communication Standards as part of the inspection process and for 
communicating their findings to their customers.  

The Motorist Assurance Program continues to work cooperatively and proactively with government agencies 
and consumer groups toward solutions that both benefit the customer and are mutually acceptable to both 
regulators and industry. We maintain the belief that industry must retain control over how we conduct our 
business, and we must be viewed as part of the solution and not part of the problem. Meetings with state and 
other government officials (and their representatives), concerned with auto repair and/or consumer protection, 
are conducted. Feedback from these sessions is brought back to the association, and the program adjusted as 
needed.  

To assure auto repair customers recourse if they were not satisfied with a repair transaction, the Motorist 
Assurance Program offers mediation and arbitration through the Better Business Bureau and other non-profit 
organizations. MAP conducted pilot programs in twelve states before announcing the program nationally in 
October 1998. During the pilots, participating repair shops demonstrated their adherence to the Pledge and 
Standards and agreed to follow the UICS in communicating the results of their inspection to their customers.  

To put some "teeth" in the program, an accreditation requirement for shops was initiated. The requirements are 
stringent, and a self-policing method has been incorporated which includes the "mystery shopping" of outlets.  

We welcome you to join us as we continue our outreach with your support, both the automotive repair industry 
and your customers will reap the benefits. Please visit MAP at our Internet site www.motorist.org or contact us

OVERVIEW OF SERVICE REQUIREMENTS AND SUGGESTIONS 

It is MAP policy that all exhaust, brake, steering, suspension, wheel alignment, drive-line, engine performance 
and maintenance, and heating, ventilation and air conditioning, and electrical services be offered and performed 
under the standards and procedures specified in these sections.  

Before any service is performed on a vehicle, an inspection of the appropriate system must be performed. The 
results of this inspection must be explained to the customer and documented on an inspection form. The 
condition of the vehicle and its components will indicate what services/part replacements may be "Required" or 
"Suggested". In addition, suggestions may be made to satisfy the requests expressed by the customer.  

When a component is suggested or required to be repaired or replaced, the decision to repair or replace must be 
made in the customer's best interest, and at his or her choice given the options available.  

This section lists the various parts and conditions that indicate a required or suggested service or part 
replacement. Although this list is extensive, it is not fully inclusive. In addition to this list, a technician may 
make a suggestion. However, any suggestions must be based on substantial and informed experience, or the 
vehicle manufacturer's recommended service interval and must be documented.  

Some conditions indicate that service or part replacement is required because the part in question is no longer 
providing the function for which it is intended, does not meet a vehicle manufacturer's design specification or is 
missing.  

Example: An exhaust pipe has corroded severely and has a hole in it through which exhaust gases are leaking. 
Replacement of the exhaust pipe in this case is required due to functional failure.  

Example: A brake rotor has been worn to the point where it measures less than the vehicle manufacturer's 
discard specifications. Replacement of the rotor is required because it does not meet design specifications.  

Some conditions indicate that a service or part replacement is suggested because the part is close to the end of 
its useful life or addresses a customer's need, convenience or request. If a customer's vehicle has one of these 
conditions, the procedure may be only to suggest service.  

Example: An exhaust pipe is rusted, corroded or weak, but no leaks are present. In this case, the exhaust pipe 
has not failed. However, there is evidence that the pipe may need replacement in the near future. Replacement 
of the pipe may be suggested for the customer's convenience in avoiding a future problem.
