Under the Hood: Engine & Transmission 2018 Jeep Grand Cherokee Laredo Specs
The heart of any vehicle lies in its engine and transmission. For the 2018 Grand Cherokee Laredo, Jeep opted for a reliable and proven powertrain that balances power with everyday usability.
The Standard Powerhouse: 3.6L Pentastar V6
The vast majority of 2018 Laredo models came equipped with the venerable 3.6-liter Pentastar V6 engine. This engine has been a workhorse across the Chrysler, Dodge, and Jeep lineup for years, known for its smooth operation and decent power delivery.
- Horsepower: Expect around 295 horsepower at 6,400 RPM. This is more than enough grunt for highway cruising, merging onto busy freeways, and even some light towing.
- Torque: It delivers 260 lb-ft of torque at 4,800 RPM. This provides a good punch off the line and helps with hauling.
- Fuel Economy: EPA estimates typically range around 19 MPG city / 26 MPG highway / 21 MPG combined for RWD models, with 4×4 versions being slightly less efficient.
Keeping your Pentastar V6 in top shape involves regular oil changes (we recommend a quality synthetic 5W-20 oil, checking your owner’s manual for specific recommendations), air filter replacements, and spark plug checks around the 100,000-mile mark. Pay attention to any unusual noises or dashboard warning lights.
The Smooth Operator: 8-Speed Automatic Transmission
Mated to the Pentastar V6 is an equally impressive eight-speed automatic transmission. This transmission is a key factor in the Laredo’s smooth ride and respectable fuel economy.
- Benefits: The multiple gears allow the engine to stay in its optimal power band more often, improving both acceleration and efficiency. It also contributes to a quiet cabin experience on the highway.
- Maintenance Tips: While often advertised as “lifetime fill,” we at FatBoysOffroad strongly recommend considering a transmission fluid and filter service around 60,000 to 80,000 miles, especially if you do a lot of towing or off-roading. Use only the specified Mopar ATF+4 fluid (or equivalent) to avoid costly issues.
Drivetrain & Off-Road Capability: Understanding Your Laredo’s Stance
The Grand Cherokee name implies capability, and even the Laredo trim offers options that make it surprisingly competent when the pavement ends. Understanding these 2018 Jeep Grand Cherokee Laredo specs for its drivetrain is crucial for off-road enthusiasts.
Rear-Wheel Drive (RWD) vs. Quadra-Trac I 4×4
The 2018 Laredo was available in two main drivetrain configurations:
- Rear-Wheel Drive (RWD): This is the standard setup, offering excellent on-road handling and slightly better fuel economy. It’s perfectly adequate for most daily driving and light-duty conditions.
- Quadra-Trac I 4×4: This is where the Jeep spirit truly shines. Quadra-Trac I is a full-time, single-speed four-wheel-drive system. It automatically shifts torque between the front and rear axles as needed, without requiring any driver input. There’s no low-range gearing, but it’s fantastic for improved traction in snow, rain, light mud, or on gravel roads. This system provides significant benefits of 2018 Jeep Grand Cherokee Laredo specs for all-weather driving confidence.
For those looking for more serious off-road capability, you’d typically need to step up to higher trims like the Limited or Trailhawk for systems like Quadra-Trac II or Quadra-Drive II with low-range gearing and electronic limited-slip differentials.
Suspension & Ground Clearance: Ready for Adventure
Even in Laredo trim, the Grand Cherokee maintains a respectable stance for light off-roading.
- Ground Clearance: Most 2018 Laredo models come with approximately 8.6 inches of ground clearance. This is a good starting point for clearing obstacles on unpaved roads or moderate trails.
- Suspension: It features an independent front and multi-link rear suspension, providing a comfortable ride on the road while still allowing for decent articulation off-road.
If you plan on more aggressive off-roading, consider a mild lift kit (1.5-2 inches) and slightly larger, more aggressive all-terrain tires. This is a common modification that significantly enhances the off-road aspects of the 2018 Jeep Grand Cherokee Laredo specs guide for trail performance.
Dimensions, Capacity & Practicality: More Than Just Numbers
Beyond the engine and drivetrain, understanding the physical dimensions and capacities of your Laredo helps you gauge its practicality for your lifestyle.
Exterior & Interior Measurements
The Grand Cherokee is a mid-size SUV, offering a good balance of exterior maneuverability and interior space.

Common Challenges & DIY Troubleshooting for Your 2018 Grand Cherokee Laredo
No vehicle is perfect, and the 2018 Grand Cherokee Laredo has its share of quirks. Knowing the common problems with 2018 Jeep Grand Cherokee Laredo specs can save you time and money.
Engine & Transmission Niggles
- Pentastar Oil Cooler Leaks: This is a well-documented issue on earlier Pentastar engines, and while improved, it can still appear on 2018 models. Look for oil pooling in the valley of the engine or dripping underneath. It’s a tricky DIY fix, often requiring manifold removal. If you see signs, consider a professional.
- Transmission Shifting Quirks: The 8-speed automatic is generally smooth, but some owners report occasional harsh shifts, especially at lower speeds or when cold. Often, a software update from the dealer can resolve this. If it persists, check your transmission fluid level and condition.
Electrical & Infotainment Glitches
- Battery Drain: Some owners report mysterious battery drains. Always check for parasitic draws by disconnecting the battery and measuring amperage. Ensure all accessories, including interior lights and USB chargers, are off. A dying battery or faulty module could be the culprit.
- Uconnect Issues: The Uconnect infotainment system can sometimes freeze, lag, or experience connectivity issues. Often, a simple “soft reset” (holding down the volume and tune buttons simultaneously for 10-15 seconds) can fix it. Ensure your software is up to date.
Suspension & Steering Wear
- Front Suspension Bushings: Over time, front lower control arm bushings and sway bar links can wear out, leading to clunks, rattles, or loose steering. Inspect these components by jacking up the front end and looking for cracks or excessive play. Replacing sway bar links is a straightforward DIY task with basic hand tools.
- Tie Rod Ends: Worn outer tie rod ends can cause sloppy steering and uneven tire wear. Grab the wheel at 3 and 9 o’clock and try to wiggle it horizontally. Any play indicates wear. This is a job you can do yourself, but requires an alignment afterward.
Knowing how to 2018 Jeep Grand Cherokee Laredo specs problems early means less downtime and cheaper repairs.
Essential Maintenance & Care Guide for Your Laredo
Proactive maintenance is the key to longevity and reliability. Here’s a practical 2018 Jeep Grand Cherokee Laredo specs care guide to keep your ride in top shape.
Fluid Checks & Changes
Fluids are the lifeblood of your vehicle. Regularly checking and changing them is non-negotiable.
- Engine Oil: Follow your owner’s manual or the vehicle’s oil life monitoring system. For most, this is every 5,000-10,000 miles. Always use the correct viscosity and API-rated oil (e.g., 5W-20 synthetic).
- Transmission Fluid: While often “sealed,” we recommend checking the level and condition around 60,000 miles and considering a drain/fill. It’s not a simple dipstick check, often requiring specific procedures. Consult your manual or a professional.
- Differential Fluid: If you have 4×4, your front and rear differentials need fluid changes, typically every 30,000-60,000 miles, especially if you off-road or tow. Use the specified gear oil (e.g., 75W-90).
- Coolant: Check the coolant level in the reservoir regularly. Flush and fill every 5 years or 100,000 miles with OAT (Organic Acid Technology) coolant, as specified by Mopar.
- Brake Fluid: Over time, brake fluid absorbs moisture, reducing its effectiveness. Consider flushing every 2-3 years.
Tire & Brake Inspections
Your tires and brakes are critical for safety.
- Tire Pressure & Rotation: Check tire pressure weekly and rotate tires every 5,000-7,500 miles to ensure even wear and maximize lifespan. Proper pressure is essential for handling and fuel economy.
- Brake Pads & Rotors: Inspect your brake pads for wear every oil change. Look for at least 3mm of pad material. Check rotors for deep grooves or warping. Don’t let your pads wear down to the metal – it’s dangerous and can damage rotors.
Pro Tips for Longevity
- Listen to Your Jeep: Pay attention to new noises, vibrations, or smells. They are often early warnings of developing issues.
- Regular Inspections: Beyond fluid checks, visually inspect belts, hoses, and suspension components every few months. Look for cracks, leaks, or loose parts.
- Address Small Issues Early: A squeaky belt is cheaper to replace than a seized accessory. A small oil leak is easier to fix than a catastrophic engine failure.
- Know When to Call a Pro: While we encourage DIY, some jobs require specialized tools, diagnostic equipment, or expertise. Don’t hesitate to consult a qualified mechanic for complex issues or safety-critical repairs like brake line work or airbag system diagnostics.
These 2018 Jeep Grand Cherokee Laredo specs tips will empower you to keep your vehicle reliable and ready for any journey.
