2018 Jeep Wrangler Electrical System Problems

The contact owns a 2018 Jeep Wrangler. The contact stated that while driving at an undisclosed speed or while starting the vehicle, the instrument panel was inoperable. The contact stated that the instrument panel failed to illuminate and remained blank. The vehicle was taken to an independent mechanic, where it was diagnosed with instrument cluster failure. The contact was informed that the instrument cluster needed to be replaced. The vehicle was not repaired. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 130,000.

Numerous lights flash on dash-engine fan turns on high speed, coolant temp stops reading, check engine light comes on, unable to accelerate. Pull over but will not turn off. From what I’m reading it’s the CAN bus module and from what I’m finding on this site Jeep has many electrical failures but can’t fix it? Jeep should do what’s right and stand behind its product.

The electronic part of the dash stopped working. This has been an issue on many jeeps of this year with no recall to get it repaired

CAN Bus is failing and giving me issues! Power steering stops working, auto stop start fails, I was taking off at an intersection and my vehicle lite up like a Christmas tree and would not shift out of first gear causing me to pull off the road at a dangerous spot.

The contact owns a 2018 Jeep Wrangler. The contact stated that while her son was driving approximately 70-75 MPH, the vehicle stalled. The check engine and traction control warning lights were illuminated. Upon research, the contact associated the failure with NHTSA Campaign Number: 18V524000 (Electrical System). The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 138,000.

The contact owns a 2018 Jeep Wrangler. The contact stated that while driving approximately 55 - 65 MPH, the instrument panel suddenly failed to illuminate, then completely went black. While attempting to fix the failure, an image of the type of vehicle was displayed, and the instrument panel illuminated intermittently. Over time, the instrument panel only illuminated with a blue light but failed to display the temperature, mileage, and other necessary safety information. The contact became aware of NHTSA Campaign Number: 24V652000 (Electrical System); however, the VIN was not included. The dealer was contacted and confirmed that the VIN was not included. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was unknown.

Unknown, but when I attempted to accelerate onto a highway, and the engine threw the check engine light along with the electric throttle light and the traction control system. The battery was still show 14.3volts, the oil pressure was in range and the temperature of the engine was normal. The vehicle wouldn't go faster than about 20-25mph with out shifting hard and or the RPMs rev high to shift. The mechanic said both batteries are shot and the electric mapping system maybe faulty.

The contact owns a 2018 Jeep Wrangler. The contact stated that while driving approximately 55 MPH, the instrument cluster went black. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The contact researched online and related the failure to NHTSA Campaign Number: 24V652000 (Electrical System); however, the VIN was not included. The failure mileage was approximately 123,000.

The fuel pump relay that is embedded within the Totally Integrated Power Module (TIPM) failed on my 2018 Jeep Wrangler JK Unlimited after only 47391 miles, causing intermittent engine stalls and problems starting. When taken to the Sisbarro Deming, NM CDJR dealership for repair, there were no replacement TIPMs in the stock system available to fix my vehicle, despite my vehicle being only 7 years old. This suggests an abnormally high rate of failure if the manufacturer is unable to maintain an adequate stock to support their vehicles. Given this has been an issue with Jeeps of previous model years (1), it is evident the problem has not been addressed yet.

The part that failed on my 2018 Jeep Wrangler JL with 2.0L I4 Turbo or 3.6L V6 eTorque engine is the BPCM: Part Name: Battery Pack Control Module (BPCM) Part Number: 05057870 or 68381513AA My dealer advised the the battery was "bloated" and at risk of catching fire & exploding. Under further review, the very SAME part was recalled for 2020-2024 Jeep Wrangler plug-in hybrid electric vehicles. [XXX] Mopar advised that my 2018 Jeep Wrangler Unlimited Sahara with eTorque has a BPCM which is part of the 48V mild hybrid system, which is not installed in all Wranglers — only those with the eTorque system. I believe this setup in my Jeep is the SAME setup as in the 2020-2024 Jeep models which had the recall. There is much evidence of this same issue with the eTorque setup online to reference. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

We found cracks in the battery from swelling. We know for certain that the BPCM needs to be replaced. This issue is the same one the NRTA did a recall on for 2020+ Jeep Wrangler models. I had the issue fixed (was un-driveable) and it cost me over $4000. Looking for detail on why 2018 models weren’t considered in the latest recall.

I lost power steering while driving due to bad can bus connector cause by poor solder joints.

ABS module has failed and has shut off the cruse control system. The O.E. module is on national back order with no idea of it availability. The unit is still in the vehicle. Non-A.B.S. brakes work. How ever the traction control system is shut off as well as the cruse control system posing a greater risk to all. Search on several internet sites confirms that this issue has been noted to the manufacture with no resolution. Owners are left to find their own part and none are available.

My car randomly illuminates every light on the dashboard and my speedometer will say zero mph and I lose all power steering and have to put my car into neutral and roll to a stop because my brakes won’t work either. Then I cannot turn off the ignition or accessory. Check engine light is on and my car starts but there are no brakes or power steering. Thankful my kids were not in the car!

On August 6, 2025, while driving at approximately 65 mph on the highway, the vehicle experienced a sudden and total loss of motive power. The engine warning lights illuminated, and the vehicle would not accelerate, forcing an emergency maneuver across multiple lanes of traffic to reach the shoulder. This failure occurred just one day after a warranty repair for the same issue, and followed a previous 199-day repair for a known camshaft defect. This sudden power loss in highway traffic created an extreme and unreasonable risk of a high-speed collision and serious injury.

After filing my first concern with the vehicle and attempting to rack my brain with answers to why a 2018 is falling apart at the seams, I can only come up with either fraud, or the vehicle has been modified in major ways and glued together only to fall apart every bump I go over. After some reading I’m questioning 49 CFR part 565 form that was turned in after I purchased the vehicle means that I possibly have a replica, “remanufactured”, or altered vehicle. I’m not sure of the legality of selling a vehicle built from whatever vehicles I have, I do know that parts are not all the same years upon scanning modules I got some strange replacement identifiers that I will send. I also question if it really passed emissions being that my short term fuel trim sensor passed the catalytic converter on both sides stays over 99% consistently, also one of the “inspection” reports was done 2 minutes apart and the paper states that the vehicle passed at 5:08 then failed at 5:10 pm the same day. Not many vehicles tend to try again after passing and 2 minutes apart. I would have never bought a vehicle that not only has random foreign parts but a 2015 vehicle is also showing up under module information. I’ll never have recall information, and it seems that every system in the vehicle meant to warn or save me and my family when driving is compromised completely, yet somehow someone was allowed to pretend that I was buying a 2018 jeep Sahara unlimited with no record on carfax that what I am paying over 50 grand for with tax doesn’t just get bad gas and jump half the road when I hit a bump “because it’s a Jeep”. I should have been made aware that I was buying something scrapped, and that the odometer could be from any of them. I would like to receive a report of the form filed months after I purchased the vehicle and my entire jeep changed description and was no longer being monitored for safety. The IPC, BCM, TCM, and ECU aren’t properly communicating, and panels are all shifting.

The contact owns a 2018 Jeep Wrangler. The contact stated that the LD screen and instrument cluster were inoperable. The contact was unable to view critical safety information like the speedometer, warning lights, and the fuel gauge information. The contact related the failure to NHTSA Campaign Number: 24V652000 (Electrical System). The vehicle was taken to the local dealer, where the system was reset. The vehicle was not repaired due to parts being on back order. The contact called the manufacturer and the parts company and sent an email to the CEO. The failure mileage was approximately 60,000.

All of our warning lights would come on at once we would lose steering power then it would go dark. We’d have to pull over shut it off then we’d have to wait at least 30 minutes before we could get it back in gear to drive it anywhere. This has happened more than three times. We now have it in a dealership and want to know, I think there was a recall on it in September but we did not get a letter so we want to know how to file the paperwork to get this fixed very disappointed with this we just put 2500 into it for new camshaft and now this is going to cost us around 600. I don’t have the receipts right now to download but I can upload them when I get the copies. Just wondering what help we can get it was very scary when all the power shuts down we were very lucky not to be in an accident

Instrument cluster panel needs replacing as odometer reading is 9999999 when turning the car on. Showing as a known issue in this make/model vehicle yet this VIN is not included for some unknown reason. Would like this included for reimbursement.

I have experienced an Instrument Panel Cluster (IPC) display failure, and the vehicle is available for inspection upon request. This failure poses a direct safety risk to myself, my passengers, and others on the road. The display initially flickered and flashed, which created a driving distraction, and now it has gone completely blank. Without the IPC, I cannot monitor the speedometer, fuel level, warning lamps, or other vital vehicle information. I believe this condition violates Federal Motor Vehicle Safety Standard (FMVSS) No. 101 regarding the accessibility and visibility of required controls and displays, thereby increasing the risk of a crash. The issue has been inspected by an independent service center, which confirmed the failure and encouraged me to contact the manufacturer about a potential recall. There were no warning lamps, error codes, or messages prior to the failure. The first symptoms appeared a couple of months ago when the display began flickering intermittently. Since then, the problem has worsened to the point where the display now rarely turns on at all.
