For many Americans, reliability is just as important as performance or style when choosing a car. Few things can ruin the ownership experience like an engine overhaul, a costly, time-consuming repair that often signals the end of a car’s useful life.
Fortunately, some vehicles have proven themselves remarkably resilient, running for hundreds of thousands of miles without the need for major internal work.
The following list highlights ten cars that rarely need engine overhauls. While some are household names, others may surprise you.
All have earned their reputations by consistently delivering dependable performance and long-term value to U.S. drivers.
1. Chevrolet Impala (3.6L V6 Models)
The Chevy Impala has long been a favorite among American drivers for its spacious cabin and comfortable ride. What often gets overlooked is the reliability of its 3.6-liter V6 engine.
Many Impalas from the 2010s are still running strong with over 200,000 miles on the odometer, making them a hidden gem for buyers seeking affordable longevity in a full-size sedan.
The Chevrolet Impala 10 LT 3.6 V6, produced between 2017 and 2020, is a full-size sedan that combines power, comfort, and modern engineering. Equipped with a 3.6-liter V6 engine, this model uses GM’s High Feature LFX 3600 Direct Injection (SIDI) technology.
With a displacement of 3564 cc (217.5 cu-in), the naturally aspirated V6 produces 309 PS (305 horsepower or 227 kW) at 6800 rpm and delivers a maximum torque of 358 Nm (264 lb-ft) at 5200 rpm.
Its bore and stroke measurements are 94.0 mm by 85.6 mm, and it features a compression ratio of 11.5:1. The setup includes 24 valves, an aluminum block and head, and a transverse engine alignment, driving the front wheels through a six-speed automatic transmission.

2. Nissan Altima (2.5L I4)
The Nissan Altima’s 2.5-liter four-cylinder engine has been one of the most durable in its class. While the Altima is often overshadowed by rivals like the Camry or Accord, owners have found that the four-cylinder powerplant can handle years of commuting without serious issues.
Properly maintained, it’s not uncommon to see Altimas reaching 250,000 miles with no major engine repairs.
The 2.5-liter QR25DE engine is essentially an enlarged version of the QR20DE, with a few important differences. Instead of sharing the same crankshaft as its smaller sibling, the QR25DE features a redesigned crankshaft paired with a longer 100 mm stroke, compared to the QR20DE’s 80.3 mm.
To accommodate this, Nissan shortened the connecting rods, which allowed displacement to grow to 2.5 liters while retaining the original 89 mm cylinder bore. This increase delivered more torque, but it also placed greater stress on the cylinders, piston rings, and connecting rods.
As a result, the QR25DE is more prone to issues such as high oil consumption and came with a shorter factory warranty compared to the 2.0-liter version.
In 2007, Nissan made a number of updates to improve durability and performance. These changes included a redesigned intake manifold, new pistons, stronger connecting rods, and a repositioned balancing system located closer to the center of the block.
The engine also received new camshafts for improved efficiency and refinement. Despite these improvements, the QR25DE continued to use the same lightweight aluminum block construction as before.
From a technical standpoint, the QR25DE is an inline-four, dual-overhead-cam (DOHC) engine with four valves per cylinder. It features an aluminum block and head, electronic fuel injection, and runs on gasoline. With a bore of 89 mm and stroke of 100 mm, the displacement totals 2,488 cc.
Compression ratios vary between 9.5 and 10.5 depending on the application. Output ranges from 152 to 182 horsepower at 6,000 rpm, with torque figures between 173 and 180 lb-ft at 4,000 rpm.
The firing order is 1-3-4-2, and the engine requires approximately 5.1 liters of oil, with recommended viscosities of 0W-20 or 5W-30. Oil change intervals are typically around 10,000 miles, though exact specifications may vary by model and market.
The QR25DE has powered a wide range of Nissan vehicles over the years, including the Teana, X-Trail, Murano, Rogue, Bassara, Serena, Sentra, Presage, Altima, and Frontier, as well as the sportier Sentra SE-R.
It even appeared in the Suzuki Equator, a rebadged midsize pickup. Its widespread use underscores its versatility, though owners should remain mindful of its known weaknesses and keep up with regular maintenance to ensure reliability.
3. Buick LeSabre (3800 Series II V6)
A throwback to GM’s golden era of dependable powertrains, the Buick LeSabre’s 3800 Series II engine is legendary for its toughness.
Produced until the mid-2000s, this engine is still praised by mechanics for being nearly bulletproof. Many LeSabres continue to serve as daily drivers in the U.S., often surpassing 300,000 miles with their original engines intact.
When conversations arise about what powers American-made automobiles, they almost always circle back to V8 engines. These large, powerful motors have long been symbols of strength and performance, dominating the golden era of American muscle cars in the 1960s and early 1970s.
Yet, while the V8 may capture most of the spotlight, there are other American-built engines worthy of admiration. V6 engines, though often overlooked, have played a vital role in delivering balance, dependability, and efficiency, and one of the most respected examples is Buick and General Motors’ 3800 Series II V6.
This engine, officially designated the L36, debuted for the 1995 model year as the successor to the Series I L27. However, the 3800 lineage stretches much further back, with roots dating to the early 1960s.
By the time the Series II arrived, the engine had already built a strong reputation for reliability and fuel efficiency. Its performance in real-world driving often earned it recognition as one of the industry’s best, with frequent appearances on lists of the top ten engines of its time.
The 3800 Series II V6 was not designed to compete with high-output performance engines, as its 205 horsepower output was modest compared to larger counterparts. Instead, it excelled at being a dependable, practical engine that met the needs of everyday drivers.
This blend of durability, efficiency, and adequate power made it an attractive option for a wide range of buyers, and as a result, General Motors adopted it broadly, installing the L36 in vehicles across several of its brands.
