TPMS has been around for over 20 years. 20 years ago, they had the technology to allow us to read tire pressure. Not just tire pressure, but all of the information Which the car's computer reads, could be available to the owner. Which cars make that information available to the owner? What car allows you to get a diagnostic trouble code, instead of just seeing a check engine light? Which car allows the driver to monitor real time data? It's there. I can see it with a scan tool, or a free app on my phone.

You can use an OBD II scanner. The right software will read each tire's PSI. You could also check your tires with a manual gauge. It's possible that with a 2018, one or more TPMS sensor needs to be replaced. The batteries in those don't last forever.

You can also find bottle jacks made for unibody pinch welds, with slits on the jack saddle.

I have what looks like a hockey puck with a slit. Apparently, it works fine on my car. I just put it where the pinch weld is. The pinch wed sits nicely in the slit. But it's not an absolute must. Since my jacks and Jack stands work fine without it.

They make pads for the floor jack saddles, which have a slit for unibody cars.

It's a little bit of work, but rotate the tires. Switch the tires from left to right. Then if you're still reading the left side, and not the right side, you will know that the sensors in the tire are good.

No amount of wrench turning could fix a hum in his brain.

Just remove the visor. Then tint the top 6" or 8" of the windshield.

Possible. I would take it to another shop. Get 3 or 4 shops to look at it. Maybe one of the shops can do a computer diagnostic. Newer cars are more complicated with different computer modules. Or it could be something simple and mechanical. Like an alternator not charging the battery. Or bad wiring.

Sorry I can't help you. I know what it's like. I still have parts for cars I don't even own anymore. Anyone interested in OEM Mustang struts?

Any idea on what the total cost was? Time, labor, parts....?

Just use the wiring to the stereo. Splice into the harness.

Good optics.

Good job

For some owners, this key chart will apply. I believe that this chart is about a decade old. Newer cars made in the last 10 years will have a different type of key.
