Buying Used: What to Know About the Jeep Gladiator and Tacoma Reliability

Used truck buyers often prioritize reliability above all else. The Jeep Gladiator and Toyota Tacoma both offer rugged midsize pickups with strong off-road credentials, but they differ significantly in long-term dependability. Whether you need a daily driver that can handle trails or a workhorse with low maintenance costs, understanding the reliability profile of each model will help you avoid costly surprises. This expanded guide compares used Gladiator and Tacoma reliability in detail, covering common issues, ownership costs, and expert recommendations.

Jeep Gladiator Reliability: What Owners and Experts Say

Introduced for the 2020 model year, the Jeep Gladiator blends Wrangler-inspired off-road capability with a five-foot truck bed. While it delivers unique features like a removable top and doors, its reliability track record is mixed.

Overall Reliability Ratings

The Gladiator receives average to below-average reliability scores from major automotive research organizations. J.D. Power gives the 2021 Gladiator a reliability rating of 77 out of 100, which is below the midsize truck segment average. Consumer Reports has also placed the Gladiator near the bottom of its predicted reliability rankings for pickup trucks, citing multiple trouble spots.

  • Common issues reported by owners include electrical glitches (infotainment freezing, backup camera failures), transmission shuddering (especially in early 2020 models), and steering wander.
  • Recalls have affected certain model years. For example, the 2020–2022 Gladiators were recalled for engine control software that could cause stalling, and some 2020–2021 models had a loose driveshaft bolt.
  • Diesel engine variants (EcoDiesel) introduced in 2021 have experienced fewer complaints so far, but long-term data is still limited.

Model Year Considerations for Used Buyers

If you’re shopping for a used Gladiator, avoid the earliest 2020 models if possible. The 2021 and 2022 model years saw minor updates that addressed some initial quality issues, though the steering and transmission concerns remain more frequent than on comparable trucks. Aim for a 2022 or newer Gladiator with a clean service history to minimize risk.

According to automotive data from CarComplaints.com, the most severe complaints involve the transmission at low miles, with some owners reporting replacement costs above $4,000. Electrical issues, while less expensive to fix, are also prevalent.

Toyota Tacoma Reliability: The Gold Standard?

The Toyota Tacoma has a legendary reputation for longevity. With proper maintenance, many Tacomas easily surpass 200,000 miles and hold strong resale value. This reliability is a major reason the Tacoma consistently outsells its competitors.

Overall Reliability Ratings

The Tacoma routinely earns top marks. J.D. Power rates the 2021 Tacoma 85 out of 100 for quality and reliability, placing it in the “Great” category. Consumer Reports has given the Tacoma a predicted reliability score of 4 out of 5 or higher for most recent model years. The brand’s decades-long track record in the midsize segment provides confidence for used buyers.

  • Known issues on Tacoma models include premature rear differential seal leaks (especially on 2016–2019 models), third brake light water leaks, and a “harsh” transmission shift that many owners learn to live with. These are generally less serious than Gladiator faults.
  • Recalls have been limited and minor, such as a 2019 recall for rear suspension bolts that could loosen, and a 2020–2022 recall for missing manual transmission park rod.
  • The 3.5-liter V6 and 2.7-liter four-cylinder engines are considered very robust, with few internal issues reported across high-mileage examples.

Model Year Considerations for Used Buyers

Any Tacoma from 2016 onward (the third generation) is a strong choice, but there are minor differences. The 2016–2019 models have the most reported transmission hesitation and differential seal complaints. The 2020 refresh brought revised suspension tuning and added Toyota Safety Sense features. For budget-conscious shoppers, a well-maintained 2015 or earlier second-generation Tacoma remains an excellent value, though interiors are dated.

Reliability data from Consumer Reports shows that the Tacoma's reliability has been consistently above average across all model years since 2010, with very few patterns of major engine or transmission failure.

Head-to-Head Comparison: Gladiator vs. Tacoma Reliability

When evaluating used options, it helps to compare both trucks across several reliability-related dimensions.

Maintenance and Repair Costs

Repair costs matter over the long term. The Gladiator shares many components with the Wrangler, which can make parts more expensive than typical Toyota parts. For example, a replacement radiator for a Gladiator can cost $500–$700, while a Tacoma radiator often runs $200–$350. Labor rates are similar, but frequency of repairs tends to be higher on the Gladiator. Extended warranty coverage for the Gladiator is advisable; many buyers purchase a Mopar Vehicle Protection plan. The Tacoma’s lower repair incidence means owners often skip extended warranties without regret.

Resale Value and Depreciation

Resale value reflects long-term reliability perceptions. The Tacoma retains about 70% of its value after three years, one of the best in any vehicle segment. The Gladiator retains about 62%—still decent but notably lower. For a used buyer, this means a three-year-old Tacoma will cost more upfront but will also be easier to sell later. The Gladiator’s higher depreciation can work in the buyer’s favor: you can find gently used examples at a steeper discount.

Off-Road Capability vs. Daily Dependability

If your primary use is off-roading, the Gladiator’s solid front axle and Wrangler-derived suspension offer better articulation and ground clearance. However, that same design introduces more potential failure points (track bars, steering stabilizers) that can wear faster than the Tacoma’s independent front suspension. The Tacoma’s TRD Off-Road and TRD Pro trims still tackle serious trails with excellent reliability. For a truck that must start every day and handle rough terrain, the Tacoma is the safer bet.

Buying Tips: How to Evaluate a Used Gladiator or Tacoma

Regardless of which model you prefer, following these steps will reduce the chance of buying a problematic used truck.

Check Vehicle History Reports

Obtain a CARFAX or AutoCheck report to verify mileage, accident history, and maintenance records. For the Gladiator, look for consistent oil changes and any transmission or steering repairs. For the Tacoma, check for rear differential seal replacements and documented service intervals.

Pre-Purchase Inspection by a Specialist

Have an independent mechanic perform a thorough inspection. On a Gladiator, they should examine the steering box for excessive play, test all electrical functions, and check transmission fluid condition. On a Tacoma, they should inspect the rear differential for leaks, verify the third brake light seal, and test the transmission shift quality at low speeds.

Review Recalls and Technical Service Bulletins (TSBs)

Search the National Highway Traffic Safety Administration (NHTSA) database for open recalls on specific VINs. Also look up manufacturer TSBs — for example, Jeep released TSB 08-126-20 for steering wander on 2020 Gladiators. Toyota issued TSB 0060-17 for transmission harshness on 2016–2017 Tacomas. Knowing these can help you negotiate repairs or factor them into the price.

Consider Extended Warranty Strategies

If you choose a Gladiator, an extended warranty from a reputable provider (like Mopar or a third-party with good reviews) can offset potential repair costs. For the Tacoma, an extended warranty is less critical but may still offer peace of mind, especially for high-mileage units. Compare exclusions, deductibles, and transferability before buying.

Conclusion: Which Used Truck Fits Your Priorities?

The Toyota Tacoma is the clear winner for overall reliability, lower maintenance costs, and strong resale value. It’s the logical choice for buyers who need a dependable daily driver that will keep running for years with minimal fuss. The Jeep Gladiator, while more charismatic and arguably more capable off-road out of the box, comes with higher reliability risk and more frequent repairs. However, for those who value open-air driving, towing capability (the Gladiator can tow up to 7,700 pounds, surpassing the Tacoma’s 6,800-pound max), and unique styling, the Gladiator remains an appealing option when purchased with a warranty and thorough pre-purchase diligence.

Ultimately, your decision should align with your tolerance for potential downtime and repair bills. If peace of mind is paramount, find a used Tacoma with a documented history. If adventure is your top priority, a gently used Gladiator with a service plan can still deliver many enjoyable miles.
