Is this legit? I just got a letter saying theres a recall on my 2018 Jeep Renegade Trailhawk about a problem about oil consumption. The letter says they need to:
Reprogram powertrain module

Anyone else got that letter? Im gonna call my closest dealer after the holydays probably..

I got my recall notice 2 weeks ago. I drive a 2018 Renegade Trailhawk with the 2.4. It's an oil drinker, really sad. I bought mine new. Really like all the features of the Trailhawk but the 2.4L engine is a POS. I got the recall done and don't know yet of it will help the oil consumption issue till after I drive it a bit, but WOW it made a major difference in how this thing runs. Prior to the recall it had a dead spot below 2k RPM that was like "gee did the engine shut off???". It was a slow moving POS below 2K RPM, zero torque. After the recall it gained noticeable torque, it shifts better. It flat out runs betters and is really a different driving car now. I always expected the poor performance to improve after break in, and the dealer I got it from was very little help to me. I went to different dealer for this recall and glad I did. Get the recall. I hope it helps the oil issue but doubtful. I could see how reprogramming the computer can change performance, but oil consumption. ???? The dealer claims the computer was not operating the valves properly and it was burning the oil due to this. I asked about changing the plugs, assuming they've taken an oil bath due to this but they were not willing to do the plugs. That's ok, I'll swap them myself at 30K niles. It's at 23K now.

Hoping I get papers in the mail too. Mine may not be using enough oil to qualify for the work though.... I only go through a quart between oil changes. Still more than any newer vehicle should be going through.

I should mention I did not get anything in the mail. The only notice I got was through the smartphone Jeep app.

I received the same notice from the Mopar app earlier this month. I posted the screenshot on here at that time. I have a 2018 Renegade TH that consumes around 1qt per 1000 miles. I also received a communication from the dealer informing me of the recall. It's definitely legit - but I haven't had the work done yet so can't speak to the results. Good Luck!!! If this fixes the problem, I'll be really happy because I like my Jeep a lot - just don't enjoy worrying what damage might be happening even though I check oil often and add when necessary.

I am sceptical. Why if you have had a recall have you not simply called your Dealership to confirm:

  • Is the message true
  • Made an appointment?
If that were me I would be grabbing the bull by the horn and trying to get this fixed ASAP instead of piddling around on forums trying to convince people of a letter.

Then I would be on this forum with full glory and bragging rights to tell you what I did, how I did it and what the wonderful results are. :p:D

Well... I'm not seeing the recall help. I'm happy Jeep did the recall as it did make my Renegade perform better, but the oil consumption is not improved. I'm at a point where I'd be happy to join in on a class action event against Jeep. The car should not use oil in this fashion under any excuse Jeep or the dealership throws out there. See attached for what my oil level was at the completion of the recall and what it looks like check 282 miles later. :-(

Kaitlin, Thank you for any assistance offered. The car was purchased from Baxter Auto in Bellevue, Nebraska, but I have it serviced at the Baxter Auto in Papillion Nebraska due to the poor treatment I received from their Bellevue location. My VIN is ZAC–CJBCB8JP–H12481 the window sticker is attached. I've drove Jeep for almost 20 years now, but my Renegade has destroyed all faith I had in Jeep and certainly any trust I've had in our local dealerships. I attempted to trade it in and Baxter, or Jeep, did nothin to say "sorry, let's make this right". The car's 2.4L engine is a failure in design. I'm disappointed with it, Jeep, and the local dealer. I was actually so upset I registered baxterautosucks.com and planned on posting all my pictures, receipts from buying oil for each months top up, and intended to share with the world my story of this car and the support behind it, but then took a breath and said "why... I have better things to do". :) Sorry, if all that sounds harsh but even my past Wrangler with over 100,000 miles did not burn oil as this car does, I've spent more in oil keeping this topped off each month than I have with any other car I have ever owner. It's really sad. I you can help, that would be great.

Does anyone know what the actual defect is with these engines? I've read things about ring gaps being incorrectly aligned during assembly, and general problems with ring seal on the cylinder wall, but it's all speculation.

Defect or poor design? I agree it's all speculation until such times Jeep publicly announce its a fault.

There appear to be more satisfied owners of the Trailhawk in comparison to unhappy owners. Strangely enough, the satisfied owners don't appear to complain they are happy and that imbalance merely allows the unhappy owners case to be highlit and focused.

Let me show you another few analogies and you may see what I mean:

  • Coronovirus and mask wearing. Currently you spot the minorityof people not wearing a mask as opposed to the many that do.
  • Guns (USA excluded). Spot someone walking down the street with a gun and it's time to run. Only the minority walk down the street armed.
  • Jeep lovers are happy campers. Only a few are unhappy and always complain.
I am sure you could all copy and paste the 3 examples above and add a 4th and 5th reason etc and then we make it a sticky post :p

Personally I havent experienced that problem. Its been 2 years since I bought my TH and I have not had to add oil ever. I read about that problem and kept a close eye on the oil level. So Im a little apprehensive about letting someone mess with that...

Obviously it is a subset of the total produced, small enough that FCA can get away with trying to sweep it uner the rug. Equally clear is that they produced a pretty large number of Tigersharks that have ridiculously high oil consumption - this could be a design or manufacturing defect, or even a break-in/operation problem. Hence my question.

There are some that don't have the issue, but this is FAR beyond just a Jeep issue. This is directly from their service bulletin:

This goes back 7 years! 7 YEARS. They don't want to issue a recall because the cost would be astronomical.

Their attempt to fix it with a firmware change is interesting, as there are only few things that could affect oil consumption.

They could change when the throttle plate is closed, but this would only help if it a valve stem seal problem. A MultiAir engine will not have a low pressure inside the valve guide to pull in oil past a bad seal UNLESS the throttle plate is closed. Any other time there is (almost) atmospheric pressure right up until the intake valve, the only pressure drop would be through the air filter.

They could reprogram shift points of the automatic to reduce the amount of time running at high load and cylinder pressure. This would only help for poor ring seal & blowby. The effect of this would be to run the engine to higher rpm in lower gears, which would make it feel snappier - pretty much as described.
