My turbo failed at 75,000 miles and my wife was six hours from home. She took our vehicle to the local Mazda Service location. The replacement turbo was $1,200 and the total cost of repair was $2,900.
She left the vehicle with Mazda for one week, so they could replace/repair the blown turbo. The turbo was making whining sounds. They supplied her with a three page invoice when she picked up the car. They even replaced her spark plugs.
The new turbo blew again in 12,000 miles of the replacement of the defective turbo, but this time the engine seized up and is now worthless.
The Mazda Service shop never changed the old oil, oil filter or air filter from the defective turbo replacement 12,000 miles earlier. It's my understanding after the second turbo blew, the PCV valve was clogged with oil sludge and the engine compression built up and shot out the dip stick and most of the engine oil at the same time. The 2010 Mazda CX-7 has a bulletin regarding oil sludge issues due to poor PCV valve design.
The Mazda shop said they did nothing wrong by not changing the old engine oil. We even asked them to change the oil, because it was time. We use full synthetic oil. Money was no problem. We were already spending $2,900 for the blown turbo and they had our car for a whole week.
Every Google search, YouTube video and mechanic I speak to, knows to change the old oil after a blown turbo replacement, due to the potential hazards associated with particulate matter in the oil. The turbo is part of the engine's oil eco system. I believe the original problem was oil sludge which caused the original turbo to blow.
When I went to my Dodge dealer and other Mazda dealers and spoke to the service departments, nowhere was there a turbo repair outline that instructs the old oil be flushed and replaced during a defective turbo replacement. What?
My neighbor is a VW mechanic and a bulletin was released, instructing mechanics to flush the oil three times before replacing the old engine oil with brand new oil.
If the Mazda mechanics bothered to check my old oil, they would have seen the sludge buildup and could have prevented the second (Replacement) turbo and my engine from blowing up after only 12,000 miles.
I have lost $15,000 due to this debacle and want to take the Mazda Service shop to court for not fixing the problem, just replacing the defective (turbo) part. I am going to have a difficult time in small claims court proving my case, if I cannot find proof that Mazda requires their mechanics to change the oil when a turbo blows and needs replacement.
I did receive a list of twenty steps a Mazda mechanic must follow when replacing a blown turbo for a Diesel engine. I got this from ask. Com. Step four was to replace the old oil, oil filter and air filter. The Mazda service shop said that is true for a diesel engine, but not for a gas engine? What?
I spoke with the Director of Engineering for Honeywell and he said to replace a defective turbo and not changing the old oil, is as bad as changing a babies diaper and not wiping the baby's behind.
It is clear to me the Mazda Service department did the wrong thing. I cannot find the proof I need to make them correct the problem they created. How could my wife know to make sure Mazda changed the oil, even after we requested they do it.
I am going insane trying to stand up for what I believe and get the Mazda Service shop to admit their mistake. They said all they were required to do is top off the old oil after replacing the blown turbo. Why did they not look to see why my turbo blew in the first place? Oil Sludge!
Can anyone help!
have the same problem?
