America loves pickup trucks, which is why the US's best-selling vehicle year-on-year, every year, is the Ford F-Series. But not everyone can afford to buy a new pickup truck, which is why used truck sales are a big part of the American used car market. But buying a secondhand truck isn't like buying a normal car; most people buying a secondhand truck are likely going to use it as a workhorse, or at the very least, for its off-road or towing abilities. Reliability thus plays a pretty big factor in making the decision of which truck to buy. We recently crunched the numbers on America's most reliable trucks over the last decade, but if you're shopping in the midsize segment, one truck is more reliable than the rest.Technically, it's the 2024 to 2026 Ford Ranger, but as it's still basically a new truck and hasn't been available for long enough to paint a clear picture, which is why we're discounting it from eligibility for this feature. Instead, we've looked at any truck sold in the last 10 years that has been on sale long enough to have a proven reliability record, with at least three years being the lowest we could go. Looking at J.D. Power Quality and Reliability ratings, recalls, and complaints filed with the NHTSA, we have a winner. The most reliable midsize pickup truck of the last 10 years is the 2019 Nissan Frontier. Why The 2019 Frontier Is The Most Reliable Midsize Pickup Of The Last Decade NissanReliability can't be determined by a single factor. A multitude of elements must be considered, like being proven in real-world scenarios, considering the thoughts of owners, and tracking how many problems a truck had. Using these metrics, the 2019 Nissan Frontier comes out on top. 2019 Nissan Frontier Reliability By The Numbers J.D. Power Quality and Reliability score: 87Number of recalls: 1Number of NHTSA complaints per 1,000 units sold: 0.23J.D. Power's overall score for the 2019 Frontier is a relatively paltry 78/100, but that average was brought down by a poor driving experience (63/100) and average resale value (75/100). For Quality and Reliability, 87/100 is exceptional. Part of this stems from the fact that the 2019 Frontier was the last model year before major changes were made to the truck. By the time this model year rolled around, the second-gen Frontier had been on sale for 15 years in its current generation, with a facelift handed to the truck for its 2009 model year. With 15 years under its belt, Nissan had all but ironed out the kinks, which is why there was just a single recall for 2019, part of a broader recall across the entire Nissan lineup for faulty backup cameras.There were also remarkably few complaints leveled against this model year Frontier, with a total of 17 complaints filed with the NHTSA, equating to 0.23 complaints per thousand vehicles sold - 72,369 were sold in 2019. The Last Model Year Before A New Powertrain Came Along NissanWhile rivals may have driven better, been more technologically up to date, and been capable of towing heavier loads than the 2019 Frontier, the Nissan truck had a few things on its side. For one, the engines at the heart of the Frontier were tried and trusted. Both the 2.5-liter QR25DE four-cylinder and the 4.0-liter VQ40 engine had been in use right from the very beginning, proving themselves reliable over 15 years of service. Combined with a chassis that remained largely unchanged in those 15 years, the Frontier was as robust as they came, with multiple Frontiers reaching a million miles reliably with only standard maintenance.Typically, the later in a generation's life cycle you go, the more reliable a car or truck is, but the Frontier bucked this trend by a single year. That's because, for the 2020 model year, while the Frontier may still have been in its second generation, it inherited a new 3.8-liter V6 engine and nine-speed automatic transmission that would go on to power the next generation of the truck. We've discussed before why it's a bad idea to buy cars with new engines in their first model year, and that philosophy is largely applicable here. It wasn't so much the engine that proved problematic, but the new transmission resulted in two recalls, both for the same issue that could see the Frontier (and the Nissan Titan of the same years - 2020-2022) roll away due to a faulty transmission parking pawl. Here's How Much America's Most Reliable Midsize Pickup Costs Today When new, prices ranged from $19,290 for the cheapest S-trim King Cab 4x2 to $37,150 for the range-topping SL Crew Cab 4x4 with the automatic transmission and the shorter wheelbase.Depreciation has been kind to the Frontier, with average prices ranging from $15,346 - $21,782 for the King Cab models and $19,840 - $24,63. Naturally, that depends on trim, condition, mileage, and even which state you're in, but considering the second-gen Frontier's propensity for reaching a million miles with little to no problems, even a higher-mileage model-year 2019 Frontier is not something to worry about. Other Reliable Midsize Pickups To Consider We understand that sometimes, brand bias and family allegiance mean you might want to defy the statistics and buy something else. Sometimes it comes down to familiarity with the brand, or having someone in the family with mechanical experience with a particular brand or truck. Whatever your reasons for not wanting a 2019 Nissan Frontier, that's OK. But if you're not a Nissan or Frontier fan but still want a reliable midsize pickup truck, here are the next most reliable models: 2021 Ford Ranger FordJ.D. Power Quality and Reliability score: 87Number of recalls: 4Number of NHTSA complaints per 1,000 units sold: 0.56With an identical Quality and Reliability rating to the Frontier from J.D. Power, the Ranger is a reliable contender, despite being relatively young at just three years old. But its reliability was proven before it even arrived in the US, with this generation being tested elsewhere in the world for years before the USDM version was launched. Where it loses out to the Frontier is in the number of complaints per thousand trucks sold, with more than double the complaints for this model year. 2015 Toyota Tacoma ToyotaJ.D. Power Quality and Reliability score: 85Number of recalls: 4Number of NHTSA complaints per 1,000 units sold: 0.49Many of you might have thought the Tacoma would be the most reliable midsize pickup truck around. After all, it's an institution and America's favorite midsize truck as far as the sales figures go. But after selling 179,562 units in 2015, it picked up more complaints per thousand trucks and scored slightly less on JD. Power's Quality and Reliability rankings. This is one truck you can trust to serve you well for the long haul.
