Over the last week the tire pressure monitor light has come on. I've reset the monitor twice after confirming pressure was GTG. Anyone else have this happen? Understand temperature may be an issue. Here in DC the weather has been in the 90s, w/humidity close to 100. Getting 32 mpg/mostly highway (automatic).

My tire pressure warning light came on in the first 20 miles of driving, and stayed on for a few days, until I found the paragraph in the User Handbook describing process to reset. Be sure you follow the instructions in the manual when using the reset button. Mine has not had any issues since reset, which is about 750 additional miles of driving.

Do you mean what's described as initialization, Alvon? I've never had a car with a TPMS switch. Both my wife's car and mine show the pressure for each of the four tires.

Are people fitting aftermarket wheels using sensors?

My TPMS lite came on at 250 miles, scared me out in the middle of nowhere with no spare. All tires were right at 30 psi, so I reset. I wonder if they finally caught up to the dealer prep as I hear the cars are shipped with 40 psi and the dealer took all the air out and put in Nitrogen.

 

[Stewie]

The cars usually come with the tires over-filled though, like SUVs show up to the dealership with 50ish psi which is kind of scary lol

Mine also did it in the first 50 miles. I check that the pressure was ok and reset. It did it again about 100 miles later. It's been good since. I now have 1700 miles.

I don't have the car user manual with me -- Look in the index of the user manual for the sections on Tire Pressure Monitor System and read it carefully.

No need for valve sensor on after Market, I changed wheels and tires. Reset TPMS following the manual, everything's good!
Hope this help.

I bought mine 3 states from home and drove back. 500 miles into the trip, the low tire pressure alarm went off. Got out and looked - nothing to see. Went across the street to buy the best (and only) $2 tire pressure gauge at the Shell station and found all 4 tires read exactly 52 (!) pounds hot. The door sticker says they should be at 29 cold. Called back to the dealer and was told they must have forgotten to lower the tires from 50 pounds cold and also didn't initialize the tire warning. Apparently the alarms goes off at about 500 miles if it's never been set up. They suggested 30 or 35 pounds cold. The next morning I lowered them to 40 cold, initialized the warning system. My Classica has the stock smaller wheels and Yokohama tires. They state 52 pounds max on the sidewall. 29 on the door sticker seems like too low. I kind of like the ride at 40.

Where are you all setting your tire pressures?

I swapped rims and tires, BFG 225/45/17 they're at 34psi

I think these cars are slipping through the dealers without proper Tire Pressure Monitor initialization. If you have problems with the system, just initilize it yourself with the procedure in the Owner's Manual on page 120.

Also, I'll bet dollars to donuts that only 50% of the new 124s have their chassis plugs installed.

Dealer PDI (ex. Chassis plugs & tire pressure) is cause for concern given it may very well be an indicator of things to come regarding recommend service/maintenance. To date, 1900 miles, averaging 31.2 mpg (auto/mostly highway), terrific/smooth ride.

Wow, I am sure glad we have this thread. I have been driving around with 50+ in my tires. I knocked it down to about 31 for each and reset the TPMS. Luckily I only have about 300 miles on the car. I never thought of this.

 

[wedgewa]

Now where do we look for those chassis plugs? I'm imaging how much fun it could be to visit a local dealer and say I bought this car from a dealer in another state but would you mind checking to see if they put in the chassis plugs?

 

[ameridan]

Here's where the plugs go

they should be installed (or in your "glove box"). It'sa DIY, but you'll need a mirror to see that area...

 

[Romanojoe]

Thank you Ameridan. With the underbody picture you shared, and amirror and flash-light, wife and I installed the plugs in minutes. Just went over 2000 miles ... All good.

 

[Chipshot]

But everyone's giving their dealer high marks for the delivery experience, right?

Thanks so much for posting this. That's the way to be a good member of the community. For those of you doing this, it can be done without jacking up the car, but raising it sure makes the job easy.

Good job Darrel. I don't think very many dealers are doing a good job with these cars. Thankfully the online community and vendors will fill in the gaps.

I guess in all fairness to my dealer, I bought my car as it was rolling off of the truck. I didn't give them a chance to do much to it. Thanks to you and ameridan I found the little holes and plugged them too.
