History of Jeep

Origins in WWII

The origins of Jeep can be traced back to WWII and the U.S. Army’s need for a light reconnaissance vehicle. In 1940, the Army issued a bid for a vehicle that was lightweight, could climb steep hills and maneuver through mud, sand and snow. American Bantam was the first company to submit a prototype that met the Army’s criteria. This prototype was later improved upon by Willys-Overland and Ford, leading to the standardized military model known as the Willys MB.

The Willys MB, with its distinctive flat grille and boxy shape, was rugged, durable and versatile. It was dubbed the “Jeep,” a nickname that stuck. After WWII, Willys trademarked the Jeep name and began producing civilian models based on the MB. The CJ (Civilian Jeep) series launched in 1945 and quickly gained popularity as an agile utility vehicle well-suited for farming and recreation.

Growth and Evolution

In the following decades, Jeep continued to grow and evolve with changing tastes and demands. Important models included:

  • Wagoneer (1963) – The first luxury 4×4, setting the stage for future family-oriented SUVs. Offered an automatic transmission and creature comforts.
  • Cherokee (1974) – The 2-door sporty SUV that helped usher in the compact SUV craze. Known for its off-road prowess.
  • Wrangler (1986) – Modern iteration of the CJ series, with a focus on off-road capability. Extremely customizable.
  • Grand Cherokee (1993) – Jeep’s entrant into the full-size SUV segment. Premium features with impressive off-road ability. Huge sales success.

Jeep has changed ownership several times over the decades, being bought and sold between larger automakers like AMC and Chrysler. It is currently owned by the Stellantis auto group. Through all the changes, Jeep has stayed true to its identity as the definitive manufacturer of rugged, no-nonsense 4×4 vehicles.

Higher trims may also have limited-slip or locking differentials to prevent wheel spin and keep you moving.

Off-Road Tech and Hardware

Jeeps are packed with hardware and tech to boost off-road performance:

  • Skid plates – Protect vital components like fuel tank from rocks and debris.
  • Suspension – Features like solid Dana axles, long suspension travel and Fox shocks improve articulation and handling over rough terrain.
  • Selec-Speed Control – Low-speed cruise control modulates throttle and braking for steadier rock crawling abilities.
  • Tow hooks – Front and rear tow hooks allow you to be hauled out if stuck. Highly useful during recoveries.
  • Hill Start/Descent – Brake assist features that provide control going up and down steep inclines.

Trail Rated Badge

Jeeps carrying the Trail Rated badge have passed tests in five key off-road areas: Traction, Ground Clearance, Maneuverability, Articulation and Water Fording. Trail Rated Jeeps like the Wrangler Rubicon and Cherokee Trailhawk excel off-road.

Jeep Brand Perception and Place in Culture

Beyond just being rugged SUVs, Jeep vehicles hold a unique place in American culture with symbolic meanings. The brand image carries perceptions related to freedom, authenticity and capability.

Symbol of Freedom and Patriotism

As the original WWII military vehicle, Jeep is entwined with ideas of duty and service. It’s a symbol of American patriotism and freedom. Driving a Jeep lets you feel a sense of independence and adventure. Open-air Jeep models connect you with the elements.


In an age of crossover look-alikes, Jeep has maintained distinct design cues for decades. The seven-slot grille and round headlights instantly identify a Jeep. This consistency gives the brand an aura of authenticity. Driving a Wrangler or Gladiator elicits a nostalgic, iconic feeling.

Outdoor/Adventure Lifestyle

Jeeps are closely aligned with an active, outdoor lifestyle. They enable accessing surfing spots, climbing rocky cliffs to camp, or cruising across the dunes. Jeep taps into ideals of enjoying natural beauty and exploration. Owners tend to identify as outdoor enthusiasts.

Buying Considerations for Different Jeep Models

When buying a Jeep, you’ll want to consider factors like capability needs, passenger space, fuel efficiency, and intended use. Here are key considerations for popular models:


  • How much off-roading and customization do you envision? The more extreme use, the higher spec (Rubicon) you may want.
  • Do you require 4-door practicality or prefer classic 2-door style?
  • Soft top or hard top? Determine how open you want the driving experience to be.
  • Analyze how your mod plans (tires, lift kit, etc) might impact on-road manners.


  • How much truck capability (towing/hauling) do you need? This guides choices like powertrain, axles, etc.
  • Determine whether the bed length and storage are sufficient for your cargo needs. Open bed or tonneau cover?
  • Assess lifestyle fit – does the adventure-oriented Gladiator align with how you plan to use it?

Grand Cherokee

  • Match capability and luxury features to your budget. The higher the trim, the more luxe and tech-focused.
  • Gauge whether you really need V8 power, or if a V6 provides enough performance.
  • For family duty, verify rear seat room meets needs, and the cargo space fits strollers, sports gear, etc.
  • If off-roading, consider augmenting 4×4 systems with options like locking diffs and skid plates.


  • The Cherokee spans wider on-road (Latitude) to off-road (Trailhawk) ability. Choose where you land on that spectrum.
  • 4-cylinder base engine delvers fuel economy; opt for the V6 for power. Choose drivetrain accordingly.
  • Check latest tech features against rivals to determine if Cherokee keeps pace on infotainment and driver assists.


  • As an entry model, the Compass comes well-equipped but has fewer options. Determine if you can live without add-ons.
  • Test storage space and cabin room to make sure it can accommodate passengers and gear for daily use.
  • Stick with FWD for maximum economy, or upgrade to 4×4 for inclement weather capability if needed.
  • Understand it trails pricier Jeep models in off-road performance. Manage expectations accordingly.

Tips for Outfitting and Modifying Jeeps

One of the joys of Jeep ownership is customizing your rig through modifications and gear. Here are some tips:

Lift Kits

Adding a lift kit helps increase ground clearance for larger tires and serious off-roading. But don’t overdo lift height – 1.5 to 3 inches is often ideal for capability versus on-road handling.

Wheels and Tires

Opt for rugged all-terrain or mud-terrain tires for traction off-road. Match tire size carefully to intended use. Consider upgrading to heavier-duty alloy or steel wheels for stability.

Armor and Protection

Beef up vulnerable areas like bumpers, differential covers, control arms and transfer case with aftermarket armor. Rock rails and skid plates add vital protection from trail obstacles.


Better lighting improves visibility on dark trails. Install auxiliary LED light bars and cube lights to illuminate the path ahead. Go for LED headlights and fog lights for clearer vision.

Winches and Recovery Gear

A sturdy winch lets you self-recover when stuck off-road. Combine with tree straps, shackles, hitches and a tow strap for extraction capabilities. Other key gear: gloves, tow hooks, jack.

Electrical System

Upgrade wiring, fuses, alternators and batteries to handle additional electrical load from mods like lights, winches and onboard gear. A dual battery setup prevents getting stranded out on the trails.

Storage and Cargo

Add protective cargo mats and liners to haul dirty gear. Install roof racks for extra cargo capacity outside the cabin. Pickup models benefit from bed covers and organizers to secure cargo during off-road driving.

Common Problems and Reliability Issues on Jeeps

While Jeeps are built rugged, they are not immune to problems. Being aware of common issues can help you evaluate used models and avoid headaches.

Leaking/Cracked Soft Tops

Laminated soft tops can leak at the seams or windows over time. Zippers also fail. Avoid too much sun exposure and use protectants to prolong top life. Factory tops tend to hold up better than aftermarket. Hard tops reduce leaks.

Overheating Issues

The Wrangler/Gladiator’s iconic grille design isn’t ideal for airflow. Upgraded radiators, fans, and hood vents can help manage engine heat. Keep the A/C condenser clean. Watch engine temps when wheeling on hot days.

Transmission Problems

Jeep’s automatics are not known for longevity, especially when subject to hard off-road use. Harsh downshifts, slipping and leaks are common by 100K+ miles. Proper maintenance and driving style helps prolong transmission life.

Rust Prone Body Panels

Poor drainage around windshields, rear frames, fender flares and rocker panels causes Jeep body rust over time. Touch up paint chips quickly to avoid future rust. Wash undersides regularly. Aftermarket protection products can limit rust issues.

Poor Gas Mileage

Aerodynamics and 4×4 drivetrains contribute to mediocre fuel economy, especially in the Wrangler and Gladiator. Real-world economy is often 2-3 mpg below estimates. You must accept compromise here. Light off-roading helps curb thirst.

Electrical Gremlins

Faulty window controls, radio glitches and wonky sensors point to flaky electrical components in some Wranglers. Check for TSBs on issues and inspect wiring harness, connectors and grounds for problems. The complex onboard electronics can prove finicky and troublesome.

Difficult Soft Top Operation

Over time, sagging fabric and plastic window distortion makes folding the soft top more difficult. Joints become less flexible as well in older tops. Maintain proper tension and lubricate zippers to avoid excessive force when opening/closing.

Steering Wander

The solid front axle on Wranglers and Gladiators – while great for articulation off-road – contributes to steering wander and looseness on-road. Upgraded stabilizer bars and steering dampers can tighten up feel. Proper alignment also crucial.

Clutch Wear

The clutch inevitably wears out faster with off-road use, given the heavy loads and high heat it endures. Learn to use low gears to limit slippage and ride the clutch lightly during technical sections. Expect more frequent clutch replacements if you off-road extensively.

Door Hinge/Latch Issues

The removable doors on Wranglers can sag over time, causing alignment and latch problems. Hinge bushings and pins wear down, requiring replacement. Lube hinge points and check latch adjustment regularly to avoid issues.

Oil Leaks

Frequent water submersion when off-roading exposes seals to contamination. Watch for leaks near gaskets, o-rings and block/head mating surfaces if you play in mud and streams. The 3.6L engine may leak near the rear main seal as well.

Wheel Bearing Failure

Premature wheel bearing failure plagues some Jeep models after 30K to 40K miles. This causes rumbling/grinding from the wheel hub. Most common on Grand Cherokees but an issue on Wranglers as well. Factory bearings seem prone to early wear.

Paint Fading

Due to thin paint or lack of UV clearcoat, some Jeep models suffer from quick paint fade and oxidation. This gives the paint a dull, chalky appearance that worsens yearly. More prevalent with lighter paint colors. Waxes and sealants help prolong a good shine.

Poor MPG from Lift Kits

Adding a suspension lift kit throws off the factory ride height and alignment, reducing aerodynamic efficiency. Taller tires also hurt fuel economy. A 2-3 inch lift cuts mpg by 1-2 combined. Not a deal breaker, but lift kits do sacrifice some efficiency.
