Jeep Gladiator start-stop problems

Filed Dec 27, 2025 · Electrical, Engine · AZ

The camshaft went out, along with the rocker arms, cam phasers, there is a box on the passenger side wheel well that goes out and will not allow the truck to shift or go into park. There is now something wrong with the automatic start/stop as the light continues to be on in the dash. Things started to go out as soon as the warranty expired… The truck has 80kmi. We fix one problem only for more to pop up. We purchased the jeep brand new and everything since it has had one problem after another.

Hi - So my 2021 Jeep gladiator has 2 batteries. The battery that controls the auto start-stop system failed (while driving). I was at a light on a busy road and the auto stop/start kicked in at a light but because of the failed second battery with no warning, my Jeep died would not start backup and I was unable to even get it into neutral. So I was forced to sit in heavy traffic until the wrecker came. My complaint it why no warning and why did it go into auto stop mode when the battery was in a failed situation.

While driving in rush hour traffic, stop and go driving, a service shifter message started to intermittently appear, then the forward collision warning message started to frequently chime in and off, then I lost power steering, check engine light illuminated, other messages auto start stop service, service sway bar disconnect, transmission was stuck in 3rd gear then after a stop it would not shift out of 1st even switching to manual shift mode, was able to pull over to side of road. Turned off the vehicle, used my code reader to clear the codes, started the vehicle back on and everything was clear and vehicle drove as normal. Sure glad it didn’t happen at speed! I have read of other people having the same issue so I wanted it to add my concern as well.

Multiple issues occuring starting (documented) at 22,719 miles (09/27/2022) - stop/start and remote start had not been functioning properly - vehicle died. Required towing to dealer. Both batteries were dead. Upon leaving dealer they had not reconnected stop/start. Fast forward to 05/04/2024 and vehicle once again unchargeable to start. Took warrantied battery back to dealer and they wanted us to tow it there to check. We spent 350.91 to replace ourselves due to a lack of confidence with Jeep. Then on 05/20/2024 took it to a 4x4 center and discovered multiple issues with vehicle from manufacturing and dealer work. To start -- 1) the rear differential pinion seal is leaking 2) the power stearing box is aluminum and showed signs of flex and contact 3) dealer installed lift was incomplete leaving the front axle off center (visually observed about a 3" offset).

The ESS/Auto Start/Stop system is unavailable rendering the remote start for cold weather unavailable. This issue also effects the reliability of the battery and electrical supply as a whole potentially leading to unexpected engine stoppages and stranding due to a no start scenario. The issue is widespread and well documented among 2018-Current Jeep Rangler models as well as 2020-Current Jeep Gladiator models. Causes are reported by dealers ranging from premature failure of the start/stop auxiliary battery to TPM/distribution box failures. My vehicle has experienced this issue twice with the first occurrence shortly after purchase. With many of the effected vehicles reaching the end of their warranty period, the number of vehicles circulating on highways will increase creating a safety hazard. Further, the failure of this system may create an EPA compliance issue as the ESS/Auto Start/Stop system is required equipment to meet EPA fuel economy standards for the fleet.
