Will a catch can void my new car warranty?

zupesterLT1 · 01-08-2021, 02:55 PM

Will the installation of a mishimoto catch can void my new car warrant? Dealer likes to give the impression that any modification under the hood could result in my forfeiting my new car warranty. (see my thread on CAI)

It is easy to put on and take off. Just uninstall when bringing the car in for work.

Depends in the dealer. They'd be stupid to turn away warranty work just because of a catch can

2SS Capt · 01-09-2021, 08:41 PM

It shouldn't, but if the dealer wants to be a dick, honestly they would really need to prove that the catch can caused the problem... On that note, they are easy to install and remove, I took mine in for an ECO flash after I had an issue and I removed my catch can prior, just to avoid any issues... The Mishimoto looks so factory, honestly, unless they work on Camaro's all the time, I doubt they'd even notice (mine has the Black Strut Tower brace so my catch can is even more hidden)...

the dealer doesnt have to prove anything. you have to prove it didnt at your expense. The dealer can void it. Some dealers have no idea what a catch can is. If its not in the GM accessories catalog they think its going to blow the car up. Ask your dealer if they care. If they know anything about cars they will be fine with it. If not and they tell you it will void it just remove it. If you need any warranty work or take it to the dealer for maintenance take it off. Dont feel its dishonest. They are being dishonest by telling you it will void it.

Thanks, for the insight. I will install it and remove it before I take it into the dealer for work..

There is no reason to use a CC on a NA street driven vehicle. You will not get deposits that affect anything with today's motors. If your car dies on the road and is taken direct to a dealer there is a very good chance Chevy will deny any warranty claim. There are no upsides to doing this, only a waste of money and potential for a denied warranty claim.

JSH · 01-10-2021, 12:23 PM

Yea, forget about a CC. I'm not yet convinced mine needs one.

I keep whatever tools I need to remove the Catch Can in my car, while I'm waiting for AAA I'd be taking the Catch Can off...

Mine Mishimoto Catch Can caught this much oil in about 400-500 miles... Not insignificant...

Even if it only reduces any potential buildup on the valves by 50%, that is still a significant reduction (I'm guessing the real number will be closer to a 75% reduction)...

a catch can is definitely needed. especially on DI motors. all that oil burns onto the valves and doesnt get washed off. thats why GM recommends having them cleaned every ( i forget how many miles).

Really? I'd be interested to see that recommendation.

Without debating the usefulness, or lack thereof, of a catch can.The answer to your warranty question is, maybe. It is a modification to the PCV system after all.

If your dealership chooses to, they can essentially ignore any modification (relevant or not) and honor the warranty and complete any repairs. However, sometimes GM requires a full diagnostic download before honoring a specific warranty repair. Then they will use any anomaly found that can be contributed to a modification to deny the warranty. Anything you do that causes your car to work outside the original factory engineered parameters can be used as an excuse.

When you add a catch can, is the PCV system working as designed and engineered by GM? For example; Blown seal? That's because your catch can caused an increase in internal engine pressure due to the modification of the crankcase ventilation system. Warranty denied! Although it defies logic that your catch can would do that, it's a modification to the system that can be used as an excuse to deny your claim.

***I am not saying anything like that will, or will not, happen, I am just using this as a hypothetical scenario to illustrate a point.***

Now this thread about warranty coverage can continue its spiral into a discussion of the effectiveness of a catch can as almost all threads that mention a catch can do.
