Dealership sucks. TPMS questions

[King Nothing]

About a year ago I put 35s and Rocktrix wheels on my JT. I bought a new set of OEM TPMS sensors and had them installed. After a few months the TPMS failed and now doesn’t read anything. First one wheel dropped, then another, then the other 2 at once, all within a month. The dealer is telling me that the OEM sensors “can’t handle” 35s and they need to put aftermarket sensors in for $575. I told her there are 10s of thousands of people running 35s on OEM sensors both on stock wheels and aftermarket but they refuse to go any farther with it. I guess my next step will be to swap the wheels and tires with my wife’s JLU and see if my JT reads her sensors or if her Jeep reads mine.

Where did you buy the sensors from and who installed them?

On the surface, they should be covered by the MOPAR Parts 24 month unlimited mileage warranty and also labor installed by the dealer or another shop.

The problem though is if you bought them online from another source and not the dealership you are dealing with, they can push back.

I agree, the dealership sounds like dicks and may have an out right or wrong to not honor the warranty if installed into aftermarket wheels.

It is odd though for them to fail that quick together.

I bought the sensors from a member on the wrangler forum but my dealer doesnt know that. As far as they know I had my OEM sensors swapped over when I had the wheels and tires done. They actually tried to tell me that I didn’t have sensors at all. When I corrected them on that they then decided that OEM sensors “can’t handle” 35s even though they operate at similar pressures. The sensor doesn’t care what size the tire is. I’m not trying to get them to warranty the sensors. I just want them to investigate the possibility that the problem is on the truck side, not the sensor side. If I bought bad sensors that’s on me

Run from that dealer, go to Discount tire and be done with it

It’s not the sensors, it’s the wheels and the inability for the module in the truck to read them for some reason. Be it the material or extra thickness etc..who knows. I’ve had this issue for a year since my new wheels and tires were put on by the dealer. Same sensors were fine in the stock wheel. For me it’s the left front only. Any good sensor from another position on the vehicle that is swapped to the left front won’t read. I am told it’s due to that tire being furthest from the module in combination with an after market wheel. Apparently this is quite common and began happening when the TPMS module was relocated into the cab instead of its original location somewhere near the truck box before ( from what I’m told). There is not a damn thing the dealer can do or will do since the vehicle is modified. It’s so DUMB, but I’ve just been living with it until someone comes up with a fix.

That would make sense if they hadn’t worked fine for 6 months after they were installed. We’ll find out when I swap wheels with my wife and see if the problem is with the wheels or the truck

FYI there was a TPMS cut over in mid 2021, depending on the year your truck is and the year your wife is, the TPMS wont be compatible. Sounds like the dealer just doesnt want to try, should be able to tell if the sensor is bad using the hand held. Size of tire doesnt matter since its riding on the same 17" rim.

They’re both 21s so hopefully they’ll be compatible

It all depends on your build date. If it was after June 2021 the TPMS part number changed. The new Mopar part number is 68339096AB.

We owned both by then so they are both the earlier build

Yes, and the reason for the change was supply issues. They moved the receiver from being a dedicated TPMS receiver to the RF hub. A remote start antenna issue can impact the later TPMS functionality but since this is the early version - it's likely the TPMS receiver itself.
(Jimmy can correct my terminology)

Have the dealer put down in writing they have to order "aftermarket" TPMS sensors because the factory ones won't work. $500+ for wheel sensors is ridiculous.

I bet they walk that shit back real quick. My local dealer tried some nonsense like that with my wrangler, and when I asked them to put exactly what they said, they magically found the real problem.

Did you use traditional weight tire balancing, or bead media?

Something to consider, you MAY need to replace your sensors:

Direct TPMS sensors commonly use radio frequency technology to transmit measured tire pressure readings to a vehicle’s on-board electronic control unit and warn drivers of a 25% or more under-inflation level.

Mounted inside a tire assembly on valve stems or wheel rims, the sensors are usually powered by 3-volt lithium ion batteries, but some use 1.25-volt nickel metal hydride batteries. There are developments underway that promise battery-less sensors in the future, having the potential to dramatically change TPMS markets.

For now, though, the batteries – generally round and encased in a sensor’s molded plastic housing – have finite lives. Since the batteries are entombed, a dead or dying one requires the replacement of its entire sensor assembly.

just some info for you to consider.

I had aftermarket sensors installed on my aftermarket wheels, it reads fine in the truck and it was only about 30 bucks a wheel. the batteries do die though as stated above. just my .02 good luck.

For what it's worth I had an identical problem with my 2020. I took it to two different dealers who would "relearn" the sensors and they would be working when I left but at least one would be out by the time I got home. Then they would start coming and going. Dealers both claimed it was because I had non-OEM wheels and wouldn't diagnose further.

My solution was to go rogue (and cheap) and invest a few dollars on a BeadBuster, TPMS programmer, and some programmable Autel MAXItpms sensors from Amazon. I figured 'What could go wrong?' and changed the TPMS sensors myself. It's going on eight months with no issues; even the tire fill alert works.

I'd be totally shocked if any sensors had dead batteries after only 3 years. I've seen them last easily double that and my neighbor says his went something like 7 years on their Ford Escape.
We've never lost a sensor, never lost a sensor battery.

And in his case - more than one? Not going to happen like that unless they were cheap non-MOPAR replacement junkers.
Sounds like the sensors may be a year old (to him, anyway) and I doubt they are old enough to see batteries going bad.

Did you use traditional weight tire balancing, or bead media?

Media/beads are worthless, crap, in tires this small. I'd never let anyone use such means for balancing on my tires.

The dealer is telling me that the OEM sensors “can’t handle” 35s

I'd ask them - what the heck is there to handle? They measure pressure, not diameter of the tire or the weight of the tire. And bigger tires take lower pressures - so as long as they can go down to your tire pressure, where's the problem?
Maybe if you ordered kryptonite wheels that magically block signals or act as some sort of Faraday cage........... but you only need to point out all of the Jeep owners running 35s in the country who have stock MOPAR sensors in their wheels. Even at that, 25 bucks a pop to install sensors times 4 is 100 bucks, and a set of sensors will be under 150 for 4, so we're at only 250 for a set installed unless they use some aircraft sensors or something.
