Good point.

Is there a way for me to check that they did it?

When I picked the Jeep the ESP and BAS lights came on. They initially said "one of your wheel sensors is bad".
I replied all were fine when I dropped the Jeep and you said there were no error codes.
They took it back in and said it was "ABS module not communicating with TIPM" and spent about 10 minutes working on it.
Brought it back and apparently now everything OK.

However, it would be good to check they updated this one. Even though, I would imagine that when Chrysler "refurbishes" them doesn't it load the latest firmware?

I have no idea... Maybe a scanner will display the firmware version? You'd think it would be the latest version, but with their track record so far I'd be leary. 😎

You have to be very careful with the TIPM failures.

As you saw in my Jeep's case, it led to shutting the engine down, despite the dealer could not explain 100% why. They blamed the wipers' control module, but based on this failure, it's not related.

The worst part is that they said Chrysler is aware of this issue but hasn't done anything about it.

The JL has the potential to fail the same way.

Sorry for all the issues you are having.

You keep saying Chrysler is aware of the issue but hasn’t done anything about it. There are over 1.5 million JKs on the road with TIPM and many millions other FCA vehicles with it. Basically every FCA vehicle from 2007 til 2013 used it (some even longer). There isn’t a huge epidemic of vehicles randomly turning on wipers and killing engine so it isn’t a design flaw, it is something with your vehicle.

The fact that you have failed 3 TIPMs means something else is causing it to fail. You don’t fail 3 TIPMs in the exact same manner unless it is something in the wiring causing the board to get fried. All the TIPM is is essentially a huge SPOD, a bunch of relays and transistors. Something is overloading the circuits causing it to fail. I have worked in field service in many industries and intermittent electrical issues are the worst to find. What usually happens eventually is the bad circuit finally burns up the wiring and then u can find it. Otherwise it is a very tedious troubleshooting process than unfortunately many techs now won’t do. They just change parts and hope it fixes it. On yours it needs to be taken further.

Also JL doesn’t have potential to fail same way as it doesn’t even have a TIPM, it uses PowerNet which has been used in FCA vehicles since 2013.

I'm just saying what the dealer's technicians told me when I asked how could a wiper module failing or going nuts cause an engine shutdown, which is a deadly situation. I am a mechanical engineer with experience in controls and software industry.

I asked them if Chrysler is aware of an issue can easily lead to a deadly situation. When it failed the first time and killed the engine my family and I were very lucky that the highway was empty and we were in a straight line.

Their answer was "Yes, they are aware but did not issue any specific fix for this issue so far". So, not reassuring at all, isn't it? Ah, and this one at least looked at the issue. The other did not even know how to start fixing it.

They also said that their system did not log any error code this last time it failed, and the Jeep was online. So, a fault that has the capacity to damage a TIPM and throw the wipers nuts does not generate any fault codes???

I also told them it was very suspicious that two (not three) TIPMs failed exactly the same way and suggested something else might be the cause. Their reply was that Chrysler does not make new TIPMs. They only refurbish them, hence they were not surprised with the multiple failures.

I agree with you that this is suspicious. However, I do not have the scanners the dealers have to test that stuff myself.

Furthermore, there have been piles of complaints about TIPM failure in Chrysler vehicles. The company has somehow been able to get the lawsuits dismissed. This is well documented.

You also mentioned burned wires. Well... burning Jeeps are not that uncommon, isn't it?

As far as Chrysler no longer using TIPM, yeah... good for them. However, the way their dealers handle this kind of failure does not inspire any confidence in their capabilities, neither the newer stuff Chrysler came up with also does not have its "Easter eggs". The JL, for what I see is even more dependent on electronics. Considering how the JKs have issues the probabilities in the new line is likely orders of magnitude higher.

I understand Chrysler trying to improve the design and features. However, the minimum we expect is that they own it, mostly considering how much they charge for their cars.

I completely understand and accept the "it happens" part.
What I do not accept is the manufacturer not being able to fix neither having a clue on how to do it.
Let's not forget that Jeeps are very expensive. They are not in the low-end price points.

Dealer couldn’t fix Dad’s pickup. A shade tree mechanic did, though.

Nope. Most of the times it was as dry as it gets.

And while on trails I went through shallow creeks without issues.

It's always the same routine, even after they replaced the TIPM and the wipers' control. Wipers start by themselves and when I switch the wipers' knob on (remember it was off) the engine dies. Only starts again after I reboot.

One telltale I told the dealer but did not seem relevant to them. My Jeep's remote unlock works differently sometimes. It normally unlocks the driver's door on first push and then the others on the second. Sometimes it unlocks all at the first push. Also the headlights sometimes turning on when I unlock is not consistent. And it burns blinker bulbs like crazy. Have to replace them every two or three months. Tried LEDs but only get the fast blinking so went back to incandescent.

Hello! I hope you still use this app as I am having similar problems so wanted to know what ended up happening after the TIPM was replaced under warranty...did you continue to have problems or did you trade it in??

My wipers just stopped working even though I never had any problems with them...got a new motor and they still did not work so I was told my TIPM needed to be replaced. Prior to my wipers not working, I have random things happen. My batteries only last a few years and the last one died last month when it was less than a year old. Every time prior to my batteries dying, I have the same problems with my remote inconsistently locking or unlocking my doors...I have not noticed about the headlights, though?? I also go through blinker bulbs...the last one did not even last one year.

who told you your TIPM needed to be replaced?

Honestly the wiper switch at the wheel is probably more likely the problem then the TIPM. Did you check fuses already?
The remote sounds more like the batteries in the fobs, or sometimes the contacts get dirty and make intermittent connection.
Do you have access to a good scanner like a Snap-On or Autel? If you can get your hands on one the modules will probably tell you what is going on, and you can go into live data and see the switch status while you activate the wipers.

Yes, that was the first thing checked...they were fine so the dealership said it was probably the motor. It was late Friday afternoon when the wipers stopped working so they did not have time to work on it before the bomb cyclone hit the south so my dad also got a new motor which he grounded and plugged in which did not work, either. After the bomb cyclone, I took it back up to the dealership which is when they said it was the TIPM...the dealership originally told me that there have been times that the motor has been replaced then it ends up being the TIPM. The wiper module in the switch as well as the switch are the only wiper part we have not tested. Are you able to test it or do you have to replace them like the motor to see if that is the problem??

In regards to the second part of your post, I will share that information with the dealership as I am about to work on a summary of problems I have had that have fuses in the TIPM and I will post it here as it seems that if it is the TIPM and we do not figure out what caused it to be replaced it is going to need to be replace, again...ugh!!

Thank you for any information you or anybody is able to provide me...it is very much appreciated!!
 
Based on my research, it seems that if we do not figure out what caused the TIPM to need to be replaced then it will need to be replaced, again…most likely during the warranty period. It also seems that the causes are related to corrosion (which I did not see) or inconsistent power due to the battery (which appears in my replacement list below a lot so my guess it would be it as well as there is always corrosion built up on it that never is cleaned off until the battery is replaced then only the excess is cleaned off instead of all of it) or bad connection/wiring (so my replacement list below details all things that have needed to be replaced that have a fuse in the TIPM). I find it odd that both the blow motor and TIPM are both constantly on backorder so they may be the problem with my vehicle as well as many other vehicles??

Other potential causes of the wipers not working that I have come across are the motor (my dad bought a new one which he plugged in and grounded that did not work, but he did not install it nor test the old motor via external method), the wiper module and/or switch, and there is mention of the clock spring (which seems to be related to the airbags so I am confused by its mention). Can any of these things be tested or do they just have to be replaced to find out if they are the problem??

Thank you for any information…it is greatly appreciated!!
