Frequently Asked Questions

Do you have a warranty?

Yes! It is 24 months/24,000 miles

During the Warranty Period, Jake Johnson's Garage will repair or replace, at no charge, products or parts of a product that proves defective because of improper material or workmanship, under normal use and maintenance. Our warranty covers most repairs. 

The following are examples of repairs not covered under our warranty:

  • Dealer sourced parts (warranty will be 12 months/12,000 miles for all repairs involving dealer parts)

  • Used parts (no warranty)

  • Any tire related repair (patches, balancing, alignments)

Warranty work must be performed in our shop and original (defective) part(s) must be provided. The warranty repair cannot exceed the original cost of the repair. Anything in excess will be the owner's responsibility.


We are members of the following warranty programs:

What is diagnostic labor?

Diagnostic labor is the time a technician spends figuring out a problem on your vehicle. This can include many different forms of testing to locate the source of your concern and analyze how to remedy it. This takes a technician that has undergone a variety of in depth training. In the majority of cases, this diagnostic fee will not be waived when repairs are performed.

Information Costs

Today's vehicles have multiple on-board computers  and sophisticated fuel, entertainment, and safety systems. As these expenses cannot be charged directly to a repair order as they occur, these costs are included in the diagnostic labor rate. Below is a practical list of some of these charges imposed on us:

  • Tire sensor reprogramming software

  • Vehicle repair and labor information software

  • ABS diagnostic software

  • Online/manufacturer technical service bulletins

  • Safety recall information

  • Fuel system diagnostic tools

  • OEM wiring diagrams with connector, ground, power distribution, and splice information

  • Charging system diagnostic software

  • Maintenance tables to view manufacturer recommended service interval data

  • Constant training of technicians on most updated information

What determines how much diagnostic I'm charged?

Every vehicle that comes in will be charged a minimum of a half hour diagnostic labor for each symptom. There of four different levels that determine how much labor is charged.

Level One:

Initial testing/inspection of issue. Examples include the following:

  • Noise complaints (belts squealing, clunking, etc.)

  • Testing cooling system (radiator, water pump, etc.)

  • Charging system testing (battery, alternator, and starter)

  • Brake inspections (pulsation, noise, etc.)

  • Suspension inspections (most vehicles) Starts at 0.5 hour

Level Two:

Initial testing/inspection of drivability concerns and emissions systems. Examples include the following:

  • Check engine light / other warning messages

  • Engine issues (misfires, surging, hesitation, etc.)

  • Transmission issues (problems shifting, whining, etc.)

  • A/C diagnostics

  • Emissions diagnostics (smoke testing, leak detection, etc.) Starts at 1.0 hour

Level Three:

Advanced drivability diagnostics and electrical diagnostics. Includes advanced pin point testing of problem area or tracing wiring issues on electrical systems. Also includes issues that occur intermittently.      Starts at 2.0 hours

Level Four:

Includes all previous levels. For in depth testing of issues not covered under initial two hours. Also includes multiple system diagnostics.                                                                                                                             Starts at 3 or more hours

What are Job Supplies?

These are one of the charges on your bill that include many different miscellaneous materials that were needed to repair or maintain your vehicle. They are charged as a percentage of the parts and labor, as this is the equitable way of charging for these materials. They often cannot be charged directly to your invoice because the cost of the unit package is greater than the amount used. The following are some of the materials that may be included under job supplies:

  • Sandpaper & Sanding Discs

  • Emery Cloth

  • Oxygen / Acetylene / Argon Gas

  • Rubber Gloves

  • Rust Penetrate / Solvent

  • Silicone Spray & Lubriants

  • Welding Wire

  • Hacksaw Blades

  • Zip Ties, Drill Bits, & Minor Hardware

  • Adhesives, Masking/Electrical Tape

  • Clips & Fasteners

  • Floor Mats, Key Tags, Toner

  • Propane

  • Wiping Cloths & Shop Rags

  • Dielectric Grease

  • Glass Cleaner, Brake Cleaner, Electrical Contact Cleaner, Fabric Cleaner, Carb/Throttle Body Cleaner, & Battery Cleaner

What are Hazmat Fees?

There are many costs associated with the hazardous materials associated with the auto repair business. Below is a partial list describing a few of these costs:

  • Removal of Waste Oil and Antifreeze

  • Proper Disposal of Used Tires (EPD fee)

  • Insurance Policy to Cover Hazards / Material Accidents

  • Removal of Lead-Acid Batteries

  • Proper Training of Employees and Vendors

What is Preventative Maintenance?

Performing regular maintenance on your vehicle can extend the life of your vehicle. Here are some examples of these services and the typical time intervals they are performed in:

Oil Service                                               Service Interval: Every 4,000 to 6,000 miles

Engine oil is the lifeblood of the engine. It cleans, lubricates, and cools the various moving parts inside of the engine. Today's engines are getting more and more advanced and therefore need consistent and on-time maintenance of the engine oil to extend engine life.

Filter Services                                        Service Interval: Every 10,000 to 20,000 miles

The filters on your vehicle help to trap dirt, debris, dust, and other contaminants from the various systems in your vehicle. These filters include: engine air filter, cabin air filter, and fuel filter. Engine air filters should be changed every other oil change to ensure proper engine life. Cabin air filters filter the air coming through your HVAC system. Changing this filter prevents irritants and allergens from getting into the cabin of your vehicle. This filter should be serviced once per year.

Transmission Service                             Service Interval: Every 15,000 to 30,000 miles

Involves removing old dirty fluid, cleaning transmission cooler lines, cleaning varnish and debris from transmission, and replacing with new fluid (and filter, if applicable). Benefits include: eliminating hard shifting, chattering, and slipping; provides cooler operation; and reconditions seals and extends life of transmission.

Power Steering Service                         Service Interval: Every 18,000 to 24,000 miles

Cleans debris and varnish from steering system. Also removes old oxidized fluid, replaces with new fluid, and reconditions seals. Benefits include: alleviating steering pump squeal, corrects hard erratic steering, prevents fluid leaks, and reduced wear.

Coolant Service                                                     Service Interval: Every 30,000 miles

Flushes entire cooling system and removes rust, scale, and sludge. Benefits include extending the life of hoses, water pump, heater core, thermostat, and radiator. Also reduces operating temperature of other systems.

Fuel Induction Service                                           Service Interval: Every 30,000 miles

Cleans air intake, plenum, injectors, intake valves, and combustion chambers. Also removes deposits from EGR passages (intake and exhaust). Benefits include lower fuel costs, smoother idle, restored power and performance, and reduces the change of costly EGR failure and/or replacement. Also prevents harmful carbon buildup.

Battery Service                                                      Service Interval: Every 30,000 miles

Includes cleaning battery terminals and applying leak detector. Gets rid of any corrosion and helps keep it from developing more. Extends the life of your battery and helps you get the full battery power.

Differential Service                                               Service Interval: Every 50,000 miles

Removes all old gear lube, refills component with fresh synthetic gear lube, and keeps bearings and gears free of varnish and deposits. Benefits include providing a smoother and quieter operation of drive-line components, eliminating "slip-pop" noise in limited slip differentials, and increasing life of drive and gear boxes.

Brake Flush                                                           Service Interval: Every 30,000 miles

Removes harmful moisture and corrosion that can collect in the lower points of the hydraulic system that causes rust and sludge to form. Benefits include extended use of brake components including calipers, pistons, wheel cylinders, and master clyinders.
