2023 Jeep Grand Wagoneer L

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 Grand Wagoneer L.

Transmission Automatic 8-spd

As the long-wheelbase variant of Jeep's full-size SUV, the 2023 Grand Wagoneer L pairs an 8-speed automatic transmission with EPA ratings of 14 mpg city, 19 mpg highway, and 16 mpg combined, figures that anchor any conversation about its efficiency. Within this model year, the vehicle has logged 44 owner complaints — with seats standing out as the most cited problem area — alongside seven recalls issued against it. For a researcher, that early volume of feedback positions the 2023 Grand Wagoneer L as a model still building its reliability profile rather than one with a settled track record to reference.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 60,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2023 Jeep Grand Wagoneer L top in one area — the seats, 3 of 44 reports (7%), well ahead of the next concern. None of this vehicle's 7 recall campaigns target the seats, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 2 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the seats pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
