Fiat Chrysler Automobiles introduced the EcoDiesel option for the Jeep Gladiator in 2021. This excited diesel fans with the idea of a strong mid-size truck. But, about 60,000 units of the CP4 high-pressure fuel pump are under recall. This could mean trouble for Jeep Gladiator diesel owners.
The 3.0L EcoDiesel engine has 260 horsepower and 442 lb-ft of torque. That sounds great. But, it has 25 less horsepower than the standard 3.6L Pentastar V6 engine. This unique engine mix brings both excitement and complexity for truck owners.
Diesel Gladiator models are a mix of off-road skills and fuel efficiency. The EcoDiesel engine can go up to 80 miles more than the petrol version. This makes it great for long trips and adventures, despite Jeep Gladiator Diesel Problems.
Real-world performance can vary from what the makers say. The diesel version gets about 26 MPG on the highway, a bit less than the 29 MPG rating. Knowing this is key for those looking into the Jeep Gladiator Diesel Problems.
