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.
BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
Campaign #26V326000 · May 21, 2026
Issue: Chrysler (FCA US, LLC) is recalling certain 2026 Jeep Grand Wagoneer and Jeep Grand Wagoneer L vehicles. The front camera wiring harness may not be connected properly, which can cause the rearview camera image not to display. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."
Risk: A rearview image that does not display reduces the driver's view behind the vehicle, increasing the risk of a crash.
Fix: Dealers will inspect and reconnect the wiring harness, as necessary, free of charge. Owner notification letters were mailed June 9, 2026. Owners may contact Chrysler customer service at 800-853-1403. Chrysler's number for this recall is 47D. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov on May 28, 2026.
