2025 Jeep Grand Wagoneer Problems: 5 Known Issues

How to Fix

First, establish the consumption rate with a documented oil consumption test at the dealer (typically a 1,000-mile monitored period). If consumption exceeds 1 qt per 2,000 miles, Stellantis may authorize piston ring replacement under warranty. Use only Pennzoil Ultra Platinum 0W-30 (factory fill specification). Check the PCV valve for proper operation — a stuck-open PCV increases oil consumption significantly. Monitor oil level weekly using the dipstick (do not rely solely on the electronic oil level monitor, which has a delayed response).

Owner tips & cautions

• WarningDo NOT ignore the oil consumption issue or just keep topping off. Document every oil addition with dated receipts showing the oil brand, quantity, and mileage. This documentation is critical for a warranty piston ring replacement claim. Stellantis requires proof of the consumption rate before authorizing the repair.

How to Fix

First, perform a soft reset: press and hold the Uconnect power/volume knob for 10-20 seconds until the screen goes black and reboots. If the issue persists, visit the dealer for the latest Uconnect 5 software update (check for TSB 08-135-22 REV. C or later). Ensure the 12V battery is in good condition — low voltage causes Uconnect instability. Some owners have required a full head unit replacement under warranty. Disable unnecessary background apps and features like SiriusXM 360L if stability issues continue.

Owner tips & cautions

• TipBefore going to the dealer, try a hard reset: disconnect the negative battery terminal for 30 minutes, then reconnect. This fully resets the Uconnect 5 system and clears corrupted cache data. About 50% of screen freeze issues are resolved by this simple reset.

How to Fix

Ensure all four camera lenses are clean — dirt, ice, or water droplets cause stitching errors and distortion. Perform a Uconnect soft reset (hold power knob 10-20 seconds) to reinitialize the camera system. Check for and install any available OTA updates (Settings > Software Update). If specific cameras consistently show a black image, the individual camera module may need replacement (front: 68488165AA, rear: 68488166AA). Side mirror cameras require mirror cap removal for access. Dealer calibration of the surround view system is required after any camera replacement.

Owner tips & cautions

• TipBefore going to the dealer for camera issues, try cleaning all four camera lenses with a microfiber cloth and glass cleaner. The front and side cameras are especially prone to salt spray and road grime that causes the stitching algorithm to produce bad composites. 30% of camera complaints are just dirty lenses.

How to Fix

Dealer software updates address some sensor calibration issues. A failed compressor must be replaced. Ensure the air lines are not kinked or leaking — a small leak forces the compressor to overwork. The system should be leveled and calibrated after any suspension work.

Owner tips & cautions

• TipAvoid constantly cycling between ride heights — each adjustment cycle wears the compressor. Set it and leave it for normal driving.

How to Fix

Clear all four sunroof drain tubes using flexible weed trimmer line or compressed air (do NOT use a wire, which can puncture the tubes). Access drain tube exit points at the front fenders and rear quarter panels. If tubes are kinked, the headliner must be partially dropped to reroute them with gentle curves. Apply silicone sealant to the drain tube connections at the sunroof cassette if they show signs of cracking. Dealer warranty repair should cover this — reference TSB 23-001-22 for panoramic roof water management.

Owner tips & cautions

• TipPreventive maintenance: pour a small amount of water into each corner of the sunroof channel (with the glass open) every 6 months and verify it drains freely at the fender/quarter panel exits. Catching a clogged drain early prevents $2,000+ in water damage repairs to the headliner and electronics.
