2024 Grand Wagoneer Engine Options
The 2024 Grand Wagoneer offers the Hurricane 3.0-liter twin-turbo inline-6 with up to 510 horsepower in high-output form, as well as V8 options. Both engine types have six or more cylinders with different cylinder 6 locations and diagnostic considerations.
Engine-Specific Diagnosis
On the Hurricane inline-6, cylinder 6 is the rearmost cylinder closest to the firewall. Turbo system issues can contribute to misfires. On V8 options, cylinder 6 is on the passenger bank with MDS cylinder deactivation considerations on HEMI engines.
Common Causes
Ignition coil failure and spark plug issues are common across engine types. Hurricane engines add turbo-related concerns. HEMI V8s add MDS system complexity.
