2020 Jeep Gladiator: sudden loss of power

Filed Nov 15, 2025 · Electrical, Fuel system · NC

The digital instrument cluster in my 2020 Jeep Gladiator has failed. The center display (LCD) went completely black, even though the backlight still glows faintly. This screen typically displays critical information such as vehicle speed, warnings, messages, and alerts. Without this display, I cannot monitor key safety information while driving. The analog gauges still function, but the central digital panel remains blank regardless of ignition mode (RUN or ON). After diagnosing the issue myself, I confirmed power was present at the fuse terminals. I inspected and replaced fuse F36, which was damaged and likely contributed to the display losing power or shorting. I also inspected related fuses F43 and F57 (BCM and IOD power supply), which were intact. This is not an isolated problem. Research shows that other Jeep Gladiator owners (especially 2020 models) are experiencing identical symptoms — black instrument displays, “Push Brake to Start” messages that stay on after shutdown, and modules not entering proper sleep mode. These issues align with the symptoms listed in TSB 08-002-21A, which relates to software and communication faults between the BCM and IPC. Jeep dealership confirmed the failure and quoted $700–$1,000 for full cluster replacement, stating there are no DTC codes and no reflash updates available, and that the cluster must be replaced outright. Jeep has not issued a recall, yet this is clearly a widespread failure affecting visibility and safety of vehicle operation. The problem poses a safety risk to myself and others. I cannot see alerts or diagnostic messages while driving. If this happened at night or during highway travel, it could increase accident risk. Jeep should issue a recall or warranty coverage extension for the instrument cluster failure in affected 2020 Gladiators.

I was never notified of Recall Y68 for my vehicle by Jeep or FCA, despite federal requirements that recall notices be sent by mail or electronic communication. I only became aware of the recall after my independent mechanic (Jay’s Auto Care, Kirkland WA) diagnosed a cylinder misfire and confirmed engine damage, and advised me to take the vehicle to Jeep. On June 26, 2025, I brought the vehicle to Rairdon’s Dodge Chrysler Jeep of Kirkland and reported the misfire, with documentation from my mechanic confirming engine damage. While the dealer performed the PCM update under Recall Y68, they refused to address the misfire and instructed me to wait until the check engine light returned before they would act further. On [XXX], when the fault reappeared, I returned immediately to the dealer. I was then told the repair would not be covered due to the time elapsed since my first visit. Jeep corporate was contacted (Case #[XXX]) but has failed to provide any resolution or even respond to my written request. As of August 2025, Jeep’s lack of recall notification, the dealer’s refusal to address a documented engine defect, and Jeep’s non-response have forced me to purchase and install a replacement engine at my own expense through my independent mechanic. Safety Concern: •The vehicle suffered continued drivability issues while waiting for Jeep’s required “re-trigger,” risking further engine damage. •Driving with a compromised engine presents safety hazards, including sudden stalling or loss of power. •Jeep’s failure to notify me of the recall and subsequent refusal to address the misfire left me with no safe or reasonable alternative. Requested Outcome: I am requesting the federal safety agency’s assistance in ensuring Jeep/FCA: 1.Properly documents whether notification for Recall Y68 was ever sent to me. 2.Provides reimbursement or goodwill coverage for the cost of the replacement engine and labor. 3.Reviews whether dealer handling of this recall complied with FCA/Fed recall INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (

I am filing a safety complaint regarding repeated and unresolved transmission issues with my Jeep. The vehicle has undergone two full transmission replacements after a $10,000 repair, yet critical symptoms persist, including transmission overheating (up to 240°F) and a loud whining noise while accelerating. These problems continue despite no warning lights or diagnostic codes, creating a false sense of safety. On August 4, 2025, the vehicle reached 240°F and produced loud mechanical noise while driving. This mirrors the same symptoms from before the original transmission repair and represents a clear safety hazard. These issues put me at risk of sudden transmission failure, loss of power, or loss of control while driving. The dealer has confirmed the overheating and replaced the transmission twice, but the problem remains. A brake hookup was also installed incorrectly, causing additional safety concerns that were only corrected after my insistence. Despite multiple service visits, Jeep refuses to: Provide a loaner vehicle Escalate to a corporate-level inspection Offer a buyback or reimbursement Jeep offered only an extended warranty with a deductible, which I declined as inappropriate given the unresolved repair. I have also submitted a formal legal demand to Jeep, which remains unanswered. The lack of diagnostic codes paired with dangerous symptoms and unresolved failures is deeply concerning. This issue should be investigated for a potential defect in the transmission system or software diagnostics. I request that the federal safety agency investigate this matter and that Stellantis/Jeep be held accountable for unsafe practices and poor post-repair support.

During normal driving, dash would display multiple warning lights. There would be traction control, ABS inactive, and transmission errors displayed on the screen. Twice, there was a loss of power steering while driving. All signs pointed to a CAN buss issue, but dealer could not/ would not find it. Doing research, I found that the CAN buss connector located behind the glove compartment was known in the Jeep community to fail and cause these symptoms. The only replacement is offered by Mopar/Stellantis. Multiple models and makes under Stellantis company use this same connector that has bad solder connections inside. It causes increased resistance inside the connector, and causes CAN buss communication errors, and setting any one of hundreds of possible DTC. In every occasion, there was a loss of stability control, ABS, and multiple occasions of vehicle being locked in Park. In two occasions, the electric assist power steering was disabled.

To Whom It May Concern, I am writing to formally report a serious mechanical issue involving my 2020 Jeep Gladiator (VIN: [XXX] rienced a complete and unexpected engine lock-up. The vehicle is now undrivable and presents both a functional and potential safety concern. Prior to this failure, there were no warning signs—no engine misfires, loss of power, burning smells, or dashboard warning lights. The incident occurred suddenly and without any preceding symptoms. I am aware of several issues affecting this model year, including: Recall 21V‑028 – Involving clutch overheating and potential fire risk in manual transmission vehicles TSB 18-024-21 – Pertaining to PCM software updates and camshaft replacement due to engine misfire (P0300) While I understand that technical service bulletins do not carry the same weight as recalls, the combination of TSB-related concerns and my complete engine failure raises questions about broader mechanical reliability and consumer safety. I have reached out to the dealership (Napleton’s River Oaks CDJR) to request evaluation and warranty support under the 5-year/60,000-mile powertrain coverage. However, I am also submitting this report to the federal safety agency for documentation and investigation purposes, in the event this issue reflects a larger pattern affecting other vehicles of the same make and model. I respectfully request that the federal safety agency review this case and consider whether further investigation is warranted, particularly if other consumers report similar issues. Please feel free to contact me if additional information or documentation is needed.

Driving down the highway at normal rate of speed, the engine light came on and then started blinking and I loss power in the engine. After about 10-15 seconds, the engine light went off and the engine regained power. A few minutes later, the same thing occurred. In the mornings when the engine was cold, the engine would sputter when idling and the check engine light would come on. The dealership mechanics found the problem to be the cam shaft lobe being scored causing piston #5 to misfire. The dealership told me that there are 12,000 backlogged requests for this part. In other words, there is a known defect in the cam shaft. The price of repair is over $4000. This needs to be a mandatory recall by the manufacturer!! 12,000 back logged requests for this part? Really? This is a safet issues because of the engine power loss while driving down the highway. My truck was in the shop at the dealership for 41 days. Ridiculous.
