When buying a car, most people focus on appearance, comfort, fuel economy, or even entertainment features, but the real heart of any automobile lies in its engine. The engine is the part that decides how long the car can serve, how much money will be spent on repairs, and whether the vehicle will remain reliable after years of use.
A stylish body or comfortable interior may bring joy for a short while, but if the engine cannot keep running with strength and consistency, the car becomes more of a burden than a blessing.
Many drivers have discovered that choosing a vehicle with the wrong engine quickly leads to constant workshop visits, mounting bills, and eventually frustration. While some affordable engines have proven themselves dependable to the point where the vehicle itself falls apart before the engine stops running.
Durability in engines is not about luxury price tags. Some of the longest-lasting engines are found in simple, modestly priced cars. Manufacturers that pay attention to design quality, strong materials, and simple engineering often end up producing engines that resist wear for hundreds of thousands of miles.
At the same time, there are engines that look impressive on paper, with higher power ratings or advanced technology, but in reality, they suffer frequent breakdowns, expensive repairs, or major failures long before the body of the car is finished.
5 Affordable Engines That Will Outlast the Car

Engines That Will Not Outlast The Car
1. Chrysler 2.7L V6
The Chrysler 2.7L V6 engine, used in vehicles like the Chrysler Sebring, Dodge Intrepid, and some Dodge Chargers, quickly gained a reputation for being one of the most troublesome engines of its era.
Many owners discovered that this engine struggled to remain reliable, and in many cases, it failed long before the vehicle itself showed serious age. The issues were so widespread that they damaged Chrysler’s image for years. One of the major problems with the 2.7L V6 is its oiling system. The passages within the engine are narrow, and when sludge builds up, oil flow becomes restricted.
Without enough lubrication, the engine experiences accelerated wear and internal damage. In severe cases, engines completely fail before reaching 100,000 miles, which is far below the expectation for a modern power unit.
Another recurring issue is timing chain failure. While timing chains are usually more durable than belts, in the 2.7L V6 they often suffer from tensioner problems and poor oil supply. Once the chain fails, the engine can face catastrophic damage, often requiring a full replacement. This makes the cost of ownership far higher than most buyers anticipated when choosing an affordable Chrysler or Dodge model.
Repair costs are another burden. The engine is tightly packed, which makes it difficult to access components. Mechanics often need extra time to service it, raising labor bills. Replacement parts are also costly compared to other V6 engines in the same class. For many owners, it made more sense to replace the entire car rather than rebuild the engine.
While Chrysler attempted improvements over the years, the 2.7L V6 remains widely regarded as an engine to avoid. It offered reasonable power on paper, but its lack of reliability overshadowed any performance benefits. Many vehicles with this engine ended up in junkyards much earlier than expected, showing how an engine can fail to live up to the promise of durability.
2. Volkswagen 1.8T (Early Versions)
Volkswagen’s early 1.8T turbocharged engine was introduced with excitement because it combined efficiency, performance, and modern design. It was used in cars like the Volkswagen Passat, Jetta, and Audi A4. While it seemed like a technological achievement at the time, it soon developed a reputation for being far less durable than many expected.
One of the main weaknesses of this engine was oil sludge buildup. Much like Chrysler’s 2.7L, the 1.8T had narrow oil passages that made it sensitive to missed oil changes. If drivers used the wrong oil or skipped even one service, sludge could form quickly, blocking oil flow and damaging internal components. In many cases, engines failed before reaching 120,000 miles, which left owners facing high repair bills.
The turbocharger itself was another source of trouble. Turbos operate under extreme heat and pressure, and when combined with poor oil circulation, failures became common. Replacing or repairing a turbocharger is expensive, often costing more than the value of an older car. For budget-conscious owners, this made keeping the vehicle far less appealing.
Coil pack failures and sensor problems were also frequent, leading to rough running, poor performance, and frequent check engine lights. While these issues did not always destroy the engine, they contributed to the reputation of unreliability and constant workshop visits.
Even though later versions of the 1.8T improved in durability, the early ones left a lasting impression as engines that did not outlast their vehicles. Many owners discovered that while the body and interior of their Volkswagens remained stylish, the engine was the weak point that brought the car’s life to an early close.
For buyers searching for long-term dependability, the early Volkswagen 1.8T serves as a cautionary tale. Advanced design and good performance mean little if the engine cannot survive the test of time.
3. Mazda Rotary Engine (13B)
Mazda is celebrated for keeping the rotary engine alive when other manufacturers abandoned it, and the 13B rotary became famous in cars like the RX-7 and RX-8. While it offered a unique driving experience and exciting performance, the rotary engine is rarely remembered for longevity. Many owners discovered that it required constant attention and still wore out much faster than a typical piston engine.
The rotary design itself brings challenges. Instead of pistons moving up and down, the rotary uses a triangular rotor spinning inside a chamber. While this allows for high-revving performance and smooth power delivery, it also leads to sealing problems.
The engine relies on apex seals to maintain compression, and these seals wear down quickly, especially if the car is driven aggressively. Once they fail, the engine loses power and often requires a complete rebuild.
Fuel economy and oil consumption are other weaknesses. Rotary engines naturally burn some oil by design, which means owners must constantly check and top up levels.
For those not familiar with this requirement, engines can easily run low on oil and suffer serious damage. Even with careful maintenance, many 13B engines need rebuilding after 100,000 miles or less, which is far below the lifespan of most piston engines.
Heat management is another challenge. The 13B generates a lot of heat, and when cooling systems are not in perfect condition, overheating can occur. This further reduces the engine’s lifespan and makes it more expensive to maintain.
While enthusiasts love the rotary engine for its sound, responsiveness, and uniqueness, it is far from an example of durability. Many RX-7 and RX-8 models have perfectly good bodies and interiors, but the engine fails long before the car itself is ready for retirement. For buyers who value reliability and long service life, the 13B is more of a passion project than a dependable daily driver.
4. BMW N20 Turbocharged Four-Cylinder
The BMW N20 engine was introduced in the early 2010s as a replacement for naturally aspirated six-cylinder engines. It was used in models such as the 328i and X3, and it promised strong performance with better fuel economy.
While it delivered on speed and efficiency, it failed to provide the kind of durability expected from a premium automaker. One of the biggest problems with the N20 was timing chain failure. The engine’s chain was located at the back, making it difficult to service and more prone to issues.
Many owners experienced complete timing chain breakage, which often destroyed the engine. In some cases, this happened at mileages as low as 70,000 to 90,000, leaving customers with repair costs that rivaled the value of the car.
Oil leaks and cooling system problems were also common. The N20 relies on turbocharging, which puts extra stress on internal parts and generates high heat. When combined with weak seals and gaskets, oil leakage becomes frequent. Cooling system failures further shorten the life of the engine, especially if owners do not catch the issue quickly.
Another concern is high repair costs. BMW engines are already expensive to maintain, but the N20’s problems made ownership particularly painful. Many vehicles with this engine ended up being scrapped earlier than expected, not because the car itself was worn out, but because the engine replacement cost was too high for most owners to justify.
While the N20 provides exciting acceleration and efficiency, it is not built for long-term dependability. Drivers expecting their BMWs to last for decades discovered that this engine was more of a liability than an asset. It shows how advanced technology does not always equal long service life.

5. Fiat MultiAir Turbo Engines
Fiat’s MultiAir turbocharged engines were introduced with much excitement, especially in cars like the Fiat 500 and Fiat 500L. They were marketed as modern, efficient, and powerful for their size. While the technology behind MultiAir was innovative, the engines quickly developed a reputation for being unreliable and short-lived compared to competitors.
The MultiAir system uses electro-hydraulic controls for the intake valves, which allow precise airflow management and improved fuel economy. While impressive on paper, this system introduced complications that led to frequent failures.
When the MultiAir unit fails, the car experiences rough running, reduced performance, and expensive repair bills. Replacing the unit often costs more than what many owners are willing to spend on a budget car. Another issue is turbocharger reliability.
Much like Volkswagen’s early 1.8T, the small turbo in the MultiAir engine suffers from high stress and oil-related problems. Failure of the turbocharger leaves the car underpowered, forcing owners into costly repairs. Combined with frequent electrical and sensor problems, these engines quickly lost their reputation for being dependable.
Durability is also disappointing. Many owners report serious failures before reaching 100,000 miles, which is unacceptable for a modern engine. Even with proper servicing, the MultiAir system’s complication and fragile design make it difficult to keep the engine running smoothly for long periods.
While Fiat aimed to bring modern innovation to affordable cars, the MultiAir engines ended up being a weak point. Many Fiat 500s still look stylish and fun on the outside, but their engines give out early, forcing owners to either spend heavily on repairs or give up on the car entirely.
For those looking for an affordable vehicle that will last, Fiat’s MultiAir engines are best avoided. They promise technology and efficiency but fail to deliver durability.
