2020 Jeep Wrangler: sudden loss of power

Filed Oct 13, 2026 · Electrical · OH

It keeps having the dashboard light up. It is ridiculous, and it is a known issue with Jeep, especially my year, but they do nothing. It is dangerous because I lose power steering, and it says many things aren't working. Jeep needs to recall their electrical system so we don't have to pay more then the vehicle is worth to fix it, just because we're out of warrenty.

On 4/28/26, my 2020 Jeep Wrangler Sahara Unlimited suffered a catastrophic high-voltage system failure, causing the vehicle to completely shut off at highway speeds on a live road. Stuck on the highway for nearly 3 hours at around rush hour blocking one lane of traffic. The dealership (Ourisman Jeep) diagnosed a failed 48V Hybrid Power Pack Unit (Part #68381513AA) under STAR Order #9575**. This sudden loss of power on the highway is a severe safety defect, and the manufacturer is refusing to cover the $3,327.94 repair or the resulting 3-week rental vehicle loss of use."

Vehicle Information: 2020 Jeep Wrangler Rubicon Complaint: I am reporting a safety issue involving my 2020 Jeep Wrangler Rubicon related to both the transmission and instrument cluster. In 2025, the transmission failed unexpectedly. The failure affected the vehicle’s ability to operate normally and created a potential safety hazard while driving. The issue required repair and appears consistent with other reported transmission problems in similar vehicles, even though my specific VIN was not included in any recall. In 2026, the instrument cluster failed, mileage at time of failure 108073. This caused loss or malfunction of critical driver information, including speed and warning indicators. This is a serious safety concern because it limits the driver’s ability to monitor vehicle operation and respond to potential hazards. These failures occurred within a year of each other and involve critical vehicle systems. I am aware that similar issues (transmission and instrument cluster failures) have been reported and/or recalled in other 2020 Jeep Wrangler vehicles, but my VIN has not been included. Given that the same components have failed in my vehicle, I believe this indicates a broader defect that may extend beyond the currently identified recall population. Safety Risk: Both failures pose safety risks: •Transmission failure can lead to loss of power or control while driving •Instrument cluster failure prevents the driver from seeing speed, warnings, and other critical information Request: I request that this issue be investigated and that the recall scope be reviewed and potentially expanded to include additional affected vehicles like mine.

The engine started to misfire due to bad components. The check engine light did not come on to indicate there was an issue until it was too late and the damage was done not only to the engine but other components as well. This was extremely dangerous as the issues resulted in loss of power while driving with my young children in the car as i had just picked them up from school. The vehicle has been inspected by a mechanic who believes that at this point the engine may need to be replaced entirely. My vehicle just passed 100,000 miles so is no longer covered by warranty and now I am stuck with over an $11,000 bill to replace my engine because it was built poorly to begin with, hence the class action lawsuit against Jeep for this particular motor.

Unknown what started the issue. While driving it, service electronic control dash light went on. The vehicle started losing power. We were able to get to the highway shoulder. Other dash lights were going on as we were moving over. Immediately after putting it in park and turning the vehicle off, smoke started billowing out from the hood. The vehicle engine was on fire and it was completely destroyed. The only on-going issue we had with it was auto start/stop with both auxiliary and main battery having to be replaced twice over the course of 4 years. There was an active recall for fuel pump component and we were on a waiting list for parts from the dealer since Sept 2023 and we were still waiting.

The ABS module failed and caused an issue while in the middle of driving it. When the ABS module failed, I lost power steering and other critical functions. When I lost functionality, errors that I saw on the dash included: “service breaks, service ABS, service shifter” etc. Luckily it didn’t cause any accidents. The vehicle is currently at the dealer service department. It has been there for 3 1/2 months waiting on an ABS module that is on back order. The dealer just advised me today that it could be another 3 months. It’s already been on order for the last 2 months.

An internal defect in the 2014-2020 Jeep Wranglers with the 3.6L Pentastar V6 engine affects its rocker arms, lifters, and related valvetrain components, including the engine control module (ECM) software that controls the precise timing and function of the lifters. Specifically, the rollers of a Pentastar engine’s rocker arms prematurely wear down, become loose, and then drop, which shifts the rocker arm out of alignment. The rocker arms then come into contact with the cam, scraping both components and creating metal debris. This Pentastar V6 engine defect creates an audible ticking sound that stems from metal particles and debris from the failed rocker arms and other components, contaminating the engine oil and circulating throughout the engine. This defect also causes engine misfires, resulting in bucking and surging, decreased engine performance, hesitation, loss of power, premature wear on internal components, and eventually catastrophic engine failure. The check engine light came on in my 2020 Jeep Wrangler with 69,000 miles. After having it read by a dealer, it showed the P219A code, Bank 1 air/fuel imbalance. The dealership told me that if the Jeep was running fine, I did not have to worry about it, as it was likely an O2 sensor. The code was cleared, and the P219A code returned the following day. It was driven approximately 500 miles before noticing that it began idling roughly and had an engine tick, which the dealership confirmed to be a valvetrain issue. The rocker arms, lifters, valves, and camshaft components of the Pentastar V6 engine in my 2020 Jeep Wrangler with 70,000 miles have failed. Three Jeep dealerships in my area and MANY online forums stated that this is a common occurrence with this engine, which has escalated my concern about this problem.

Power steering failed and lost engine power. Very dangerous and potentially life threatening event. Unit would not start again for at least 15 minutes. This is the second time this has happened since the dealership was supposed to have fixed by changing out the battery. I reiterate THESE ARE VERY DANGEROUS EVENTS AND COULD CAUSE A FATAL TRAFFIC ACCIDENT.

Randomly the check engine light will appear and the dash will display multiple messages about service needed for traction control, stability control, auto start stop disabled, service cruise control etc. Then while driving you will lose power steering and this almost caused my daughter to wreck while trying to finish a turn. Additionally when the messages appear the vehicle will not have the ability to shift so you can not reverse and once it shut off in the middle of the highway blocking traffic and almost caused multiple accidents. The dealership has replaced the battery sensor and said it was fixed. I was told to replace the primary and secondary battery to ensure it was not a battery problem and I did, however the issue still remains. Looked online for others with this issue and there are many with the exact problem. The Jeep will report the transmission temperature and oil temperature incorrectly with the gauge maxed out even if it has sat overnight. Additionally it also says to service the transmission.
