And honestly, the amount of drone that not having cats creates, it's almost not worth it. I've gotten used to it, but I feel bad for the kids in the back.

But then again maybe not. I noticed areas that appear to have been ground down by a machine on two of the four tires. In those areas the tread depth is less than the rest of the tire by one or two thirty-seconds. I suspect this is a problem and I am not sure this is acceptable. I have attached some photos showing this “grinding” as well as a comparison photo with a tire that does not have this grinding. I bought these from Tire Rack so I have sent an email. Best to get it right.

I’m pretty sure this was due to cost savings because a push button is much cheaper than a ignition key cylinder and all that goes into it.
Wrong they got sued because they lied about ignition issues at one point it was handed back to government motors for a while because of it.. a lot of people got killed because of the engine shutting off at 60-80mph
when they went over a "bump"

I Doubt this was justification to change vehicles to push-start, it's been around before they were sued and my 2018 has a regular keyed ignition along with tons of other ones

No visual in Pa. It passes emissions somehow. When I had them taken off, my mechanic at the time had no idea how they passed.

I can try and find the tests from the mechanic I take it to. It has passed for the last 3-4 years now since it's been done. It might be longer tbh.

My current mechanic is the number 1 rated mechanic in Lancaster for several years in a row. He will not touch any aftermarket parts other than stuff that is reputable like moog or arnott, dorman, etc. He likes oem and trys to use that the most unless it is a cost issue for the customer.

I can give you their info if you want
All you have to do is delete the downstream O2 sensors in the tune, so the ecm doesn’t look for them. The test can’t determine that, it can only tell if the sensors are throwing a code. Then if there’s no visual inspection, nobody knows there’s no cats.

That’s weird, and those are brand new tires, right?

that is the reason for the quicker phase out

GM has "push start" back to 2003(2004 model year)
the EV1 used a code to start it


you think your HUD(heads up display) is new tech, yeah in your dreams, it was available starting 1988 model year on select GM vehicles ..

GM still includes a chipped key as a back up to open the door when your 12v battery stops working..(it's actually hidden away on most of them )

those ignitions sucked you pull the key out (if you tilted the key slightly as you pulled it out)it would be passed the locking mechanism and can start the car with anything that could fit in the key hole. defeating the passlock2 system. there is a secondary fault with those recalled ignitions they did not replace the ignitions they just put a band-aid on them.. or the cheapest fix ever..


I drove my car for a while with no key in the ignition using that trick..(as soon as the recall was announced ) i think the E
