Depends on what the DTC is stored in the TPMS control module. I see a lot of transmitter no data or battery voltage decrease. This usually results in a sensor replacement due to the internal battery failing.

 

Aha! Once again, j3rf, you andthis website saves my arse. The local Sube dealer installed new tires a year ago so they've worked on the car before AND it still is within the Subaru 7 year Gold warranty coverage so I might be in luck. REALLY appreciate your response and information. The owner's manual really doesn't spell out what the problem might be, only that there IS an issue that needs examination by the dealer......THANK YOU.

Yep TPMS sensor replacement should be covered under Gold Plus if it does need it. This year I have been seeing a huge increase of TPMS sensor failure more commonly on that generation of Impreza/Crosstrek.

 

Question: more online research indicates that the sensors and their batteries are considered to be a normal service maintenance item and usually are NOT covered by warranty like Subaru Gold……..any thoughts?

 

Look at your paperwork for the Gold Plus information then on what it covers. Obviously I can't guarantee anything but this is what I see on my end in the Labor Time Guide in the US. "G" under SAS for the TPMS sensor means it's only covered under Gold Plus, not Classic or Powertrain.

 

Thanks again, j3rf!!! I have to download a copy of our Gold 7 coverage and see IF the TPMS sensor is covered..........

Like I wrote before, this website club is the best!

Seven years old is about right for a noticeable portion of coincell batteries to begin failing in the field. Taking measurements and powering an RF transmitter is no easy task.

I replaced them on one kid's 2018 Toyota late last year, and plan to on the others 2018 Forester next month when we replace tires.

The problem for you is that even if the one is covered under your Gold plan, the others will not be far behind. And if you are in the final months of your 7/100 plan on a 2018, you're going to end up paying anyhow when the next one quits. Go ahead and get the one done as you might as well have Subaru check out the entire system to make sure nothing else is wrong. Water leaks have killed the RKE module on more than one SJ Forester. But be prepared to look for an independent shop that can do a four sensor change at an affordable price.

The best time, of course, is to do it when you're getting new tire.

 

Thanks for the suggestions, Fibber. I'll mosey on up to the dealer next week and see what they say.....definitely understand about the probability of the other sensors crapping out sometime soon.

Thank you, sir!

BTW, you're so fortunate that you can tackle these maintenance issues your self. I haven't been under my car since I got it back in 2019. Too old, nowhere near the correct tools and an HOA that frowns on automotive DIYS geniuses.

The older we get, the less practical sliding under a car becomes.......used to do my own oil and filters BUT at 78 just yesterday, my wife would rip me a new one if she even thought that I was going to do anything more than replace a bulb or wash 'n wax. That;s why being a member of the Forester Org is such a wonderful resource.

Many thanks,

Steve
