    Motor threw a rod

    Bought 09 cts v from a dealer 2 months ago. When bought car had a tune headers exhaust air intake and under factory warranty and I also bought an extended warranty. Neither warranty wants to cover it owner of dealership doesn't know what to do. What's your opinion?

    Re: Motor threw a rod

    Having a tune will void the power train warranty. Changing parameters in the ECM is a no-no for GM.GM can't control what a tuner does and will not usually make good on any power train issue once the ECM has been modified. The dealer MUST send the ECM data to GM before they will authorize a new engine and if your car is tuned, GM will know it. I hate to say it but I think your out the cost of an engine. The dealer who sold you the car should have infomed you that you were buying a car without a GM power train warranty. If it was an aftermarket warranty, maybe you'll have better luck. Sorry to hear about this and wish you the best.

    You should at least get your money back for the extended warranty that apparently was never valid. Sorry to hear about that. It does suck.

    I would agree with this part if Maco was the one who put the tune on the car, but he didn't. He bought it from the dealer like that. In this case I think it's 100% the dealer's responsibility for selling him the car in that state, and then selling him a warranty that they knew they wouldn't honor.

    To put it another way, Maco didn't do anything that voided his warranty. He did literally nothing other than buy the car. Somebody needs to eat the engine repair or replacement cost, and I don't think it should be Maco.

    Get an attorney and go after the dealer that sold the vehicle to you like that without returning the vehicle back to stock and flashing the PCM back to a factory tune.

    You can also contact Cadillac customer assistance center to get a file going just to make sure all your issues are documented. Get them to escalate the issue up the chain and hopefully you can get something done. Sorry to hear about all this.

    Re: Motor threw a rod

    But still if the car was bought with a intake and headers it should have been a warning that the car had a tune also. The dealer is gonna use this arguement that you knew that the car was modified and you bought it.

    It's very unusual that these engines throw a rod. Almost unheard of. What were you doing to the car? Maybe the rev limiter was bumped way up with the tune or something?

    Since 2008 I know of 81 blown oem cts v engines. 78% of those failures have been in the 640 and higher hp range.
    4 cars have been stock with tunes.
    the rest have been install errors with tune errors or bad parts for the remaining.
    Rod failure or piston failure have occurred in all the 81.
    Block condition has been noted to be poor condition past 630rwhp mark with higher miles past 20k.


    Just to add to this, in case someone thinks it. I have not been responsible for any of these blown engines. All work was done at other shops all over the world in this list.

    The dealer had a specific responsibility to inform the buyer that the ecu was modified and that they wouldn't honor the warranty they were selling him. It's 100% their fault as far as I can tell. A lack of full disclosure makes them liable.

    Re: Motor threw a rod

    Im in louisiana. This car has been babied sience I got it definitely didn't do anything that would throw a rod. As far as getting a lawyer I have one on standby. The dealer I bought the car from gave me a loaner car today so hopefully something will happen I believe they r liable only time will tell. Thanks for y'all's input keep it coming maybe we can find someone that had a similar problem.

    I would read every piece of paper they gave you to make sure there is no fine print saying the car has been modified and has no warranty. Good luck, I hope it works out for you.

    Cadillac denied the claim so now it's time to start pressuring the dealership I bought it from. It definitely doesn't say that the cars been modified with no warranty. It says that I bought an extended warranty "quality guard plus."
