My 1ss was having a simple problem that if I put in park and my dash would show “put in park required”. So, I made an appointment today and took my car to the closest Chevy dealership. They took my car out for a ride for some reason and I’ve waited about 1 and half hour. After that, there was a nerd staff came and talked to me. He said my msd 2 step broke everything and my warranty is voided. I asked him to at least prove me something that showed my modification which will effect the car. He kept talking to me with the worst attitude. Then I chose to leave. When I just made a left turn right outside the dealership, I figured out my exhaust tone was way different. (Sounds like resonated rumble) I thought that was my illusion. But I did went to the backroad near my house. I gave a bit gas and I can definitely tell my exhaust tone was 100% different. After I got home, I saw that was iron things left on my exhaust tip. I called them, they said because my warranty is voided now, they do not have responsibility to take this.
my conclusion, 1)Chevy took my car for a joy ride, 2)held my 2 step until my cat blown 3) voided my warranty, bad attitude when talking to customer.

A msd 2 step hooked up to the stock ignition would void the warranty

The warranty may be voided due to the msd, but you have a case against them in that they inflicted additional damage unrelated to this. They did in fact accept liability by allowing your car into their shop and driving it. It may be a tricky battle, but I believe your next step should be contacting Chevy corporate if the management at the dealership refuses to help you.

I’d be surprised if the cats failed on a stock LT1... normally you have to run close to 1k hp to melt them.

Alvin, in the other thread you talked about modifying the exhaust for sound (muffler delete) and noted that it sounded different below 4k at light throttle (for which my first thought is AFM).

Can you see for sure your cats are gone? Did you take pics of the bits in your tailpipe? Cat material is very obvious. If you did the muffler delete then it should be fairly easy for someone with a borescope to check the cats or at least see as far as the AFM valves....?

Damn I'm sorry man. I am always hesitant to leave any of my sports cars with anyone, hell I get paranoid with my truck at the dealer. I took it in for an oil change (the free ones) and watch them ****ers on my dash cam leaning all over the fender. They left a couple scratches because they didn't use fender covers.

I skipped the two free oil changes. Did it myself. Car is still as nice as it came from the factory as a result!

I'm having a really hard time understanding what is going on in the first post but I'm betting there is more to this story. Is this a English your primary language?

First of all, thank you for all the commends who spent time to read my story. The only thing I did it to the AFM was the fuse (pulled fuse). I will check my cat asap, but I can tell my car got another exhaust tone and smell. I 2 steps for fun sometimes, but I would never hold it for too long because of the stock cat. The dealership must be playing with my 2step and blown it. The warranty is not a big deal for me, normally I won't keep my car for more than 4 years. The only thing that made me mad was the dealership. They had fun with my 2step, blown my cat and talked to me with an unrespectful attitude. So in my opinion, people whoever read this thread, avoid that dealership.

English is not my primary language, I am still picking it up. Sorry for wasting your time to try to understand my story, but thank you.

I didn't mean to offend anyone I just wasn't sure if it was a rushed post on a phone.

Sorry about the luck, maybe remove the 2 step and try another dealership?

Also, your English is certainly better than I can do with any other language so props to you.

Well, it's a bad situation. You will have a very hard time getting the dealership to take the hit if the cats are blown. How many miles did they put on the car?

The deal is, even if they did drive it, I would really doubt they did anything you haven't done a hundred times. They could very easily argue that the cat was already done before they got it, which, of course, could be a possibility.

As far as their attitude, yeah, they could've done that differently perhaps. However, misinterpreting the Magnussen Moss act to them probably didn't help either. The 2 step will void the warranty. That's the simple price of playing the modification game.

The lesson to be learned is to not take a modified car to a dealership, unless, you have a specific tech who is well versed in your modifications. Even then, don't expect warranty coverage. If your car is modified any further than exhaust and air intake, take it to a performance shop that understands the modification.

If warranty coverage is important, then leave the car as it left the assembly line, because that is what the warranty covers.

Well said, was only going to quote the bolded part but seriously the whole comment is 100%

Not saying moding your car is a bad thing but some dealers have issues with things as simple as an exhaust, just imagine on a scale where a 2 step would lay at.

This may be related to your problem LINK

Your out of warranty, if you try to sue good luck but I would save the money and do 1 of 3 things.

1) Remove all mods and drive the car for what it is and start putting money to the side if something were to happen.

2) Take the hit on the car, trade it in and find something else if warranty is very important to you.

3) Do absolutely nothing, the car should be reliable and enjoy it.

HP is no directly coorelated to melting cat converters. I worked in a muffler shop for 5 yrs and anything from a bad tune to backfiring can melt them. A 2 step can 100% cause cats to go bad all day long. I am NEVER on the dealerships side but in this case, they are probably in the right...
