Brand new 2020 Jeep Gladiator models are failing to start. Some models are dying at dealerships, and some Jeep Gladiator models are dying about six to ten days after being purchased. However, there is a solution to this problem.
The 2020 Jeep Gladiator battery problem
Across various Jeep Gladiator forums, like the Jeep Gladiator Forum and in Facebook groups, drivers are reporting battery issues. One driver was supposed to pick up their Jeep Gladiator Overland from the dealership but got a call saying the battery died.
The dealership said they were replacing the battery, but that failed to restore confidence. Another driver noticed that their 2020 Jeep Gladiator wouldn’t start after being parked for eight to ten days and was getting a second set of new batteries. Does this mean this issue wasn’t fixed the first time?
Some dealerships claimed that leaving the dome light on could cause the battery to die, but not everyone with this problem parked their Gladiators and left it on. So what can you do if your batteries die?
How to fix the 2020 Gladiator battery problem
Some fans suggest that Jeep needs to issue a recall for the dead batteries. They seem to think that Fiat Crylser Auto may have manufactured dead batteries for the Jeep Gladiator. The problems do seem to occur with the main battery and the auxiliary battery.
And on that note, yes, the Gladiator has two batteries. It has a dual-battery system. According to Jeep Equipment, One battery is used to crank the truck. This is known as the primary battery. The second battery is the auxiliary battery and is used to power accessories.
As the engine runs, power is split equally between each battery to charge them both. Also, having two batteries helps prevent the chances of ending up with a dead battery, and you get a backup source of power.
The cause of the battery problems in the 2020 Jeep Gladiator is unknown. Some people speculate that Jeep manufactured dead batteries. Once they get new ones, most people no longer have this issue.
However, others suggest that the batteries have connection issues. Loose wires may cause the batteries to drain. Once the connections are replaced, there shouldn’t be any more issues. Also, some drivers blame the auxiliary battery for draining the primary battery.
Is the battery issue covered under warranty?
While the 2020 Jeep Gladiator problem is annoying, it’s not too severe. Replacing the batteries and their connections should solve the problem. It’s not complicated or too expensive to fix, but it does take up some of your time.
On a positive note, battery issues are covered under warranty. The Jeep Gladiator basic warranty provides coverage for up to three years or the first 36,000 miles. The powertrain warranty covers the truck for the first five years or 100,000 miles.
As long as the warranty hasn’t been voided, this issue should be covered at no cost to you. Call a Jeep dealership in advance to schedule a maintenance appointment. You don’t have to return to the same dealership where you purchased your Gladiator. A local dealership will be fine.
