MOTORIST ASSURANCE PROGRAM (MAP)

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 organizations 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

vehicles (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, and Electrical Systems.

Further, revisions to all of these inspection communication standards

are continually republished. In addition to these, standards for Drive

Train and Transmissions have recently been promulgated. 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 MAP/BBB-CARE and other nonprofit

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.

MAP UNIFORM INSPECTION GENERAL GUIDELINES

OVERVIEW OF SERVICE REQUIREMENTS & 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

customers 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 manufacturers 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

manufacturers 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 manufacturers 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 customers need, convenience or request. If a

customers 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 customers convenience in avoiding a future problem.

Example:

The customer desires improved ride and/or handling, but the

vehicles shocks or struts have not failed. In this case,

replacement may be suggested to satisfy the customers

wishes. In this case, replacement of the shocks or struts may

not be sold as a requirement.

A customer, of course, has the choice of whether or not a

shop will service his or her vehicle. He or she may decide not to

follow some of your suggestions. When a repair is required, a MAP shop

must refuse partial service on that system if, in the judgment of the

service provider, proceeding with the work could create or continue an

unsafe condition. When a procedure states that required or suggested

repair or replacement is recommended, the customer must be informed of

the generally acceptable repair/replacement options whether or not

performed by the shop.

When presenting suggested repairs to the customer, you must

present the facts, allowing the customer to draw their own conclusions

and make an informed decision about how to proceed.

The following reasons may be used for required and suggested

services. These codes are shown in the "Code" column of the MAP

Uniform Inspection & Communications Standards that follow:

Reasons to Require Repair or Replacement

A - Part no longer performs intended purpose

B - Part does not meet a design specification (regardless of

performance)

C - Part is missing

NOTE: When a repair is required, the shop must refuse partial

service to the system in question, if the repair creates

or continues an unsafe condition.

Reasons to Suggest Repair or Replacement

1 - Part is close to the end of its useful life (just above

discard specifications, or weak; failure likely to occur

soon, etc.)

2 - To address a customer need, convenience, or request (to

stiffen ride, enhance performance, eliminate noise,

etc.)

3 - To comply with maintenance recommended by the vehicles

Original Equipment Manufacturer (OEM)

4 - Technicians recommendation based on substantial and

informed experience

NOTE: Suggested services are always optional. When presenting

suggested repairs to the customer, you must present the

facts, allowing the customer to draw their own conclusions

and make an informed decision about how to proceed.
