PHAD unconditionally guarantees the accuracy and quality of our work:
- The customer doesn't pay a cent until PHAD completes a thorough diagnosis and recommendation for repair. We document all findings with notes, photos, and sometimes a video camera if the issue is unusual (see PHAD on YouTube).
- If the initial diagnosis is incorrect (rare, but we are all human), we will perform the diagnosis again FOR FREE. Lost labor time and parts costs due to an incorrect diagnosis are NOT covered by PHAD.
- If the recommended repair is completed by PHAD, we guarantee the repair for 30 days.
- If the recommended repair is completed by a third party, PHAD cannot be held responsible for an improper repair. If a problem still exists after the recommended repair is complete, we will gladly take another look at the vehicle. However, if we find that the repair was completed improperly, or that the replacement part is defective, a separate diagnostic charge will apply.
- The diagnostic process often requires test driving the vehicle and partial disassembly to gain access to electronic components or wiring. PHAD will perform the necessary work and return the vehicle to the customer as it was prior to beginning any work. PHAD is fully insured, so any accidental damage to the vehicle is covered.
The PHAD 100% Guarantee in action:
Below are three real-world examples of when the "recommended repair" did not fix the vehicle, and PHAD was called back for a follow-up diagnosis:
Example 1: Misfire on 1989 Ford Bronco II V6:
Initial customer complaint on his '89 Ford Bronco II V6 was an engine misfire and low power. The initial diagnosis was a clogged fuel injector #3, and the recommended repair was to replace the #3 injector and clean the fuel rail.
After completing the repair at another shop, the engine was still misfiring. PHAD came back for a second diagnosis, and found that the technician did not fully plug in one of the six fuel injectors! After the injector was plugged back in, the truck ran fine.
In this case, the second diagnostic call was NOT FREE, since the comeback was caused by an improper repair.
Example 2: Blown fuse on 2003 GMC Safari van V6:
Initial customer complaint on his 2003 GMC Safari V6 van was that a fuse kept blowing for the reverse lights every time he shifted the vehicle into PARK. We diagnosed the problem as a faulty (shorted) Park-Neutral Safety switch. The switch was replaced at a shop, but the the fuse kept blowing. PHAD performed a follow-up diagnosis, and found the actual problem to be an intermittent short to ground of the Park-Neutral Safety Switch wiring harness rubbing on a sharp metal bracket.
In this case the second diagnostic call, including tracing the shorted wire, was FREE. We also repaired the harness for a discounted additional charge. The new park-neutral switch and installation were NOT covered. In the end, the customer was happy and his van was fixed for good.
Example 3: Crank no-start after engine swap on 2003 Jeep Liberty V6:
Initial customer complaint on his 2003 Jeep Liberty was a no-start after replacing the engine. During the diagnosis PHAD found that the CAMSHAFT reluctor ring was incorrect for the 2003 control system, since the replacement engine came from a 2004 donor vehicle. PHAD recommended that the cam sprocket should be swapped over to the replacement engine, a 4-hour job. The shop technician swapped the cam sprockets, but the engine still did not start. We came back for a second diagnosis, only to discover that the CRANKSHAFT reluctor wheel was also different between the 2003 and 2004 engines! To replace this part would have required complete engine removal and teardown, which was not economically feasible. The particular engine swap should not have been attempted in the first place!
In this case the second diagnostic call was FREE. Even though the first diagnosis was correct, it was not complete. Four additional hours of labor were spent with no result, based on my initial diagnosis. Unfortunately, this case was an expensive learning experience for the diagnostician, the technician who performed the engine swap, and the owner of the vehicle.
