I had a fuel system cleaning performed on my car (2005 Kia Rio, ~54k miles). I won't mention the shop because I don't want to drag their name through the mud (yet!).
As soon as I started the car I noticed the Check Engine light was on and a tapping noise was coming from under the hood. I drove the car for 15 miles and straight back to the shop because when I pressed down on the accelerator the noise would get louder. The sound was like a baseball card in a bicycle spoke only coming from my poor engine.
The service provider tried to tell me that the engine light was normal but supposedly looked at the car again (at least they made me wait there another hour) and told me that they checked the compression of the engine and that everything was fine in on that front and that the check engine light was due to engine misfire (spark plugs, or any number of things could be the cause.)
Long story, but the manager said he would take the engine apart but would rather that the dealership service look at it and that I needed to see if this was covered by my warranty. I made an appointment with the dealership who couldn't get me in for a week - but the dealership's diagnosis (99$ later) came back with this information:
Misfire. Coil, Spark Plug wires, spark plugs, all OK.
Compression test: #1
110 PSI. #2-#4 150 PSI.
(Could the compression changed drastically in a week? I think not if the engine light was on immediately after the "cleaning")
Valve cover removed: Gasket, Camshaft, and valves all OK.
Piston lower in Cylinder #4
Possible bent rod.
The dealership wanted over $500 to open the engine and since I didn't have this money there was more back in forth between the original service provider and myself before the dealership then opened the car up and found the bent rod and this was caused by it being hyrdo-locked.
The original service provider finally agreed to pay for the repair (Almost $1000), but still acts like that they did nothing wrong and I am "negotitiating" to get A) A refund on their service, B) The 99 fee from the dealership, and C) My mounting rental car bill reimbursed.
The dealership did all but say that the original service provider caused this problem. They don't want to get in the middle of it (legal reasons), but when the engine was apart the carbon deposits on the pistons(?) were extremely noticeable (I have pictures) and all signs and clues given to me point that it was caused by the service. The dealership said that if this happens the technician would have known immediately because he would have had to re-start the car. I have never had the engine die and had to re-start it like this - so I know I didn't cause this. The dealership also pointed out that they stand by their services and all auto shops have insurance for "mistakes" that can occur.
The service provider used the Wynn's 3-step system to screw up my engine. I've watched their training videos on Youtube. I've called Wynn's (nice folks) who referred me to their head engineer that I am waiting to hear back from. Apparently the owner of the original service provider also contacted Wynn's who said that this damage couldn't poissbly be because of the fuel system cleaning and that if it did cause damage it would have been to #4
. I looked at the engine diagram for my car and if this cleaning was put in through the fuel injector it seems to me that Cylinder #1
would be hit first.
What I guess I want to know is, how could the service technician caused this problem? How can I convince the owner of this shop that his technician made a mistake and tried to cover it up, and he still owes me around $600 dollars that I desperately need.
Any help is appreciated - will provide free computer advice in exchange. I'm a Systems AdministratorTechnician and would gladly exchange advice.
