Hard Pedal....Jeep Won't Start

[Jeep142]

Howdy All,

I have a 2019 JLU Sport S...less than 3,000 miles. This morning the brake pedal was hard - almost no give - and the Jeep wouldn't start. The dash lights up and all the electronics work fine. Seems to be getting plenty of power...just won't start. I found a thread with a similar issue and tried a few suggestions....pushing brake pedal REALLY hard, FOB near start button....nothing working. Any other suggestions? Otherwise, I'll have it towed to the dealership in the a.m. Thanks.

Did u try pushing the start button with the keyfob itself?

You can try remote start or you really have to push on the pedal. It’s not reading enough force on the brake to allow it to start

My wife's JLU has a stiff pedal sometimes after sitting overnight. Cycle through Accessory, Run, then back to off. Step harder on the pedal, and try to start. You won't break it.

I had this just a week ago. Had to push harder on brake pedal to get it sensed and started up.

Thanks for the help all. It finally started. Don't really know why, but it did. Think I'll still get it checked out tomorrow at the dealership. Have a great day!!!!!

I also originally posted this over 2 years ago with my JL. The trick is to push the brake pedal harder and you'll be good to go.

Thanks to all for the input. Shortly after the stiff brake pedal issue the climate controls went out and the ESS stopped working. Took it to the dealership and they replaced the main battery. All seems to be working fine...no more electrical issues. Shout out to Tri-Cities Dodge! Now, for some nice weather, the top down, and a Jeep that STARTS!!!!

The charging system and bad batteries of ESS equipped vehicles are starting to be the Achilles Heel of the JL. Weird things that are seemingly unrelated can happen when one of the batteries go bad. There are threads about charging, bad batteries, bad ESS batteries causing all kinds of lights to go off or other problems unrelated to the cause. Hopefully FCA comes up with a fix for this.

They won't. But others have, dual battery systems, replace that moped toy aux battery with a full sized Odyssey that could run a tank. Disable the ESS garbage. Unfortunately, not everyone needs a full size dual battery system for their usage, but I no longer stress about that stupid little battery leaving me stranded in the middle of nowhere.
