Some good points!

I’m guessing that would make a big difference. Also wondering how accurate the instrumentation in the car actually is when the ABS is doing its tap dance.

Now that would be pretty attention-getting around town, especially to the guy behind me.

So, of course most reviews of the Mach 1 are based on the cars with the Handling Package, claiming stopping distances of about 94 feet from 60-0 MPH. Mine has the base suspension, so it has the Pilot Sport 4s tires. I tested my braking today. 70 degrees, decent road, warm tires. 60-0 in 119...

Nope. I put brand new Michelin A/S 4s on it so I could drive in the cold weather. Seems to have the same little vibration as it did with the OEM tires, which seem to be wearing fine, and only had 3.000 miles on them.

Since the day I drove the car home from PA to ME, 5000 miles ago, I noticed a subtle vibration at speeds above 40 mph or so. At first I didn't notice it because of the newness of the car, the growl of the exhaust, etc. It's subtle enough that you probably wouldn't notice unless you rode in the...

I found one from another forum member. I’m sure if I need warranty engine repair the dealer will look to see if it was removed so they have another reason to do nothing.

If anyone has a factory 2022 or 2023 Mach 1 air inlet tube with the carbon trap, or just the carbon trap they'd sell cheap, please PM me. Thanks

My 2015 GT did that with factory suspension and 255/40/19 tires. It was so severe that my wife noticed it from the passenger seat. It’s called tramlining. I’m on my 4th set of tires. The Michelin AS3+ and Continental DWS tires nearly eliminated the problem. Your tires are probably too wide or...

Tramlining. My 2015 does it badly on Maine roads. I’m on my 4th set of tires. The stickier tires made it worse. Michelin AS3+ and Continental

Do you still have this car? I have a 2022 Mach 1 that shudders in 6th gear below 2000 RPM unless I am really gentle on the gas. My 2015 GT does not have any issues. Thanks!

Did you ever find a solution to this? Thanks!

What ever happened? Did it get fixed?

Mine was mounted in the trunk next to the tail light assembly, under the trunk liner. I think it had two antennas and a power plug. GM just got sued big time for this.

Although I agree it's not normal, the dealership says, "... normal". If the dealership won't stand by the factory warranty the only other option is to sell the car, which is what I think the first owner did. I think I've seen a proportionally higher rate of used Mach 1s with around 4,000 miles...

I own a 2015 GT Premium 50 Year Appearance car without Performance Package, and a 2022 Mach 1 Premium without the handling package. Both cars are Race Red. For the 2015, I had to install stiffer springs and shocks because it handled really, really badly. I like that all 4 wheels and tires are...

What are the wheels on the GT in your picture?

Cool. Thanks for the info!

Because it knows even when the car is not moving, I'm assuming there must be sensors inside the transmission itself, or perhaps on the shift linkage. Anyone know for sure. I have a TR3160 from a 2016 GT350 that I'm wondering if I can use it as a spare, but if there are sensors inside the new...

I took my car to the dealer for some warranty work and they offered to "glove wash it". When the kid who did the washing brought it out, he said, "We didn't get all the bugs off because we were afraid we'd scratch it if we rubbed it too hard." When I got home I noticed the hood decal had...
