I have pumped my car tires to 220 KPI and in 4 days, goes down to 200 KPI. It's been like this for a month. I have been on some long drives without issues (I will re-pump it to spec). Any one have this type of issue before?

Have you checked for a nail...?


Either that or the valve stem is leaking or you have a bent rim

I am gonna get it checked out soon!

Spray some soapy water on the valve stem to see. If it is the valve stem, there is a TSB on it.

My car has this problem too.
One tire has a very slow leak so I have to pump it up a few times a year.
This has gone on for the four years I've had the car but I really should get it fixed!
I have driven on several long trips from Canada to Florida etc. and the tire pressure stays constant, no problem.
But then when the car sits around or during normal usage it loses a few pounds pressure in a month or so.
I could not get access to the TSB that was mentioned, TSB 14-048.
Can somebody e-mail that to me please?
Send me a PM first if you can assist me. Thanks.

Yeah that's the TSB. Site seems to be down for the moment.
Spray some soapy water on the stems and see if they bubble. If they do, then it's covered under the TSB. The grommet needs to be replaced. On my car, the grommet was only replaced on one TPMS. The other three TPMS were seized so they replaced them with brand new TPMS.
My first leak happened last year. The last three happened this year. All four within 12 months.

LNJ, were the grommets replaced with no charge?? If no, what did it cost??

Thx, Bob

I didn't pay a cent since it was covered under warranty.

For me, it was a puncture that 'sealed' itself. It was patched up and it's now 100% good.

I wonder if they will fix it if the warranty is over 130,000KM LNJ I just bought which looks like the twin to your car same colour in and out
