| im a mechanic and i KNOW 95% of us are not rotten. Now What I do think is that 50% of them misdiag for the wrong thing, and 45% know the problem but sell the parts that may effect the symptom to cover their ass.
What if your car had a misfire due to (lets say) 5 plugs and 5 wires? Now, the GOOD mechanic (5%) just replace those 5 wires and 5 plugs to save the customer some money. The rest of the plugs and wires are just as old as the faulty ones, but are still within spec, and let it go. A month or maybe 3 months down the road, the car acts up. The client Brings the car back to the dealer and the mechanic tells them that their car is missing again, but its because of the OTHER 7 plugs and wires that are faulty this time.
If you were in this situation, How would you feel after spending $300 for plugs/wires and its starts to mis again? If i was that client, I would go to the service manager and complain about why wasn't my car fix the First Time! "You should of caught that other 7 Plugs/wires" One thing for sure is THAT mechanic just lost time & money AND the dealer just got a bad name. FYI Mechanics dont get paid the second time if the car comes back.
Your car may need motor mounts for rough idle but how do you know her car need motor mounts? It may have been changed before she bought the car. what if her car had a leak in the vacuum system, (no cel, no codes)rough idle depending on the size of the leak. |
