How Jeep schedules service: Oil Change Indicator

Jeep vehicles use the Oil Change Indicator system to signal when oil is due. Wrangler and Gladiator owners who actually use 4WD off-road should treat the schedule below as Schedule A (severe) — water crossings, sand, and rock crawling demand differential and transfer case service at half the published intervals. Grand Cherokee and Cherokee follow the standard Mopar schedule.

POWER TRAIN:DRIVELINE:DRIVESHAFT

Campaign #19V636000 · Aug 29, 2019

Issue: Chrysler (FCA US LLC) is recalling certain 2020 Jeep Gladiator vehicles. The rear driveshafts may have been incorrectly assembled without grease in the monoblock joint.

Fix: FCA US will notify owners, and dealers will replace the driveshaft, free of charge. The recall began October 10, 2019. Owners may contact FCA US customer service at 1-800-853-1403. FCA US number for this recall is V95.
