2024 Jeep Grand Cherokee L electrical problems

Filed Nov 3, 2026 · Electrical · TX

On November 3, 2026, our 2024 Jeep Grand Cherokee would not start. This is the second time this has happened. The main battery was dead and the vehicle only clicked. It would not accept a jump start, which left us stranded. Other owners report the same auxiliary battery and electrical failures on recent Jeep models, including a Wrangler that throws an auxiliary battery warning every year that goes away on its own weeks later. Jeep quoted that owner $750 to replace the auxiliary battery. A vehicle that won't start or take a jump without warning is a safety risk, especially in remote areas or bad weather. I'm asking the federal safety agency to look into the auxiliary battery and electrical system on these vehicles.

Upon starting my vehicle, my dashboard began flashing errors. All the indicator lights were lighted up (power steering, engine, collision detection, traction). The mileage began blinking on and off. Both of the light indicators on my side windows (for blindspot detection) were continuously illuminated even though I was parked and no vehicles were next to me. The error messages that were flashing on my dashboard were: Service Electronic Stability Control, Service Power Steering, Active Lane Management Limited, and Blind Spot Alert Unavailable. I have pictures of all of this. Additionally, when I put the vehicle into reverse, another error message displayed but I didn't get a picture of this message. When I drove the vehicle down the road (less than half a mile), it sounded louder as if I was revving the engine but I was not. I pulled off to the side, turned my vehicle off and then back on again, but the same error messages and lights continued to happen. I am being told by the dealership that I am responsible for this electrical issue because my vehicle is out was warranty. This is a leased vehicle and there is 43k miles on my vehicle. I have kept up with all maintenance and shouldn't be responsible for the cost of fixing this issue because it's leased and not my fault. The manufacturer should be responsible for fixing issues with their vehicles.

Dead Battery. The Telematics Bix Module (TBM) is failing to properly shut off when the car is parked. Therefore it induces a parasitic drain on the battery. We have had the battery replaced by the dealer. This problem is known to affect 2022-2025 models.

Significant electrical issues. Screens randomly turn off and flicker which prevents driver from being able to see vehicle status including speed. Vehicle also has built in charge pad which over heats and concerned could lead to wires melting and fire. Vehicle has spent multiple weeks at dealership for electrical issues but no solution has thus far been found. Viddeo shows flickering but shut off happens randomly and have not been able to catch on video. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Active Lane Management disengages itself upon start up. Sometimes says needs servicing - message disappears upon car restarting. Car states key fob is not in vehicle when it is. Car has turned on, not shifted into gear, and then not been able to be turned off. Steering input from the system is sudden and does not consistently match actual road conditions Radio screen flashes/goes black/freezes Emergency Assisted Braking system activates without a clear obstacle present Braking events are abrupt and unexpected during normal driving Both systems operate intermittently and without a consistent pattern, making the behavior unreliable Dealership has been unsuccessful in reproducing any of these problems despite picture proof provided. Has happened on multiple occasions - beginning in September 2025. Jeep/Stellantis unwilling to resolve. Safety Risk: The unexpected steering corrections and sudden braking create a risk of loss of vehicle control and increase the likelihood of a rear-end collision or other traffic incident. These safety systems are not functioning as intended and instead introduce unpredictable and potentially dangerous vehicle behavior.

Seems to be electrical / speaker related (forums state its the noise canceling system) This is a safety issue as around 20% of the time at cold start the car emits an extremely loud booming base sound that lasts 20-30 seconds. Despite only happening at startup anything that can impair a drivers senses is extremely dangerous as it impacts the driver and anything with noise happening around them. The problem has not been able to be reproduced by a dealer and they also wont incorporate the TSB unless it can be. Link below to reddit thread and a youtube video of the well known issue. [XXX] [XXX] Also, there is a link to a TSB, which you have issued, but this needs to be escalated to a recall asap.

I purchased my Jeep in 8/2024. Since purchasing this Jeep it has had an intermittent burning smell. I was told by the dealership I got it at that it’s normal for burning smells on new cars. Well 13,700 miles later it’s still doing it and a couple of times I have seen smoke coming from the hood area up closer to the windshield area. I took my Jeep to another dealership on 11/29/2025. They drove it and smelled the burning but said they have checked everything and can not figure out where it’s coming from. They had me pick it up on 12/24/2025 and told me to bring it back if it did it again. On 12/26/2025 I returned the Jeep to the service department due to smelling the burning 3 times during the 3 days I had it. The service department still has my vehicle as of 1/12/2026 with no updates. I have contacted Stellantis and they have not done anything. The date to the question of when this happened, I put in the last time it did it. The first time I do not recall exactly but I did contact the dealership in Feb 2025 to inform them my car smelled like it was going to catch on fire sitting at a stop light.

The contact owns a 2024 Jeep Grand Cherokee L. The contact stated that while driving at an undisclosed speed, there was an abnormal hissing and tapping sound coming from the engine compartment, with the check engine warning light illuminated. The vehicle was towed to a dealer, where it was diagnosed and determined that the wiring harness had failed due to rodent damage. The dealer informed the contact that the wiring insulation was soy-based and had been chewed on by rodents. The dealer stated that rodent urine and blood were found near the damaged wiring, and the area was not cleaned. The vehicle was not repaired. The contact was advised by the dealer to place mothballs under the vehicle to deter rodents. The dealer also confirmed that no protective covering or preventative measure would be installed to prevent a future failure. The contact expressed concern that the failure made the vehicle unsafe and stated that the contact was afraid to ride in the vehicle due to the issue. The manufacturer was made aware of the failure and referred the contact back to the dealer for further assistance. The approximate failure mileage was 3,332.
