5 V6 Engines That Do Not Last
1. Chrysler 2.7L V6
While Chrysler has produced some strong engines, the 2.7L V6 has often disappointed many of its owners. Found in vehicles such as the Dodge Intrepid, Chrysler Sebring, and Dodge Stratus, this engine developed a reputation for serious problems that show up much earlier than expected. For many drivers, this engine did not last as long as others in its class.
The biggest issue with the Chrysler 2.7L V6 is the tendency for oil sludge buildup. Poor oil circulation and design flaws in the cooling system often caused the oil to break down, leaving thick deposits inside the engine.
When sludge collects, it blocks oil passages, starves components of lubrication, and eventually leads to complete engine failure. Many owners reported losing their engines before hitting 100,000 miles, which is far below what most people expect from a V6.
Another problem linked to this engine was the water pump placement inside the block. When the water pump failed, coolant often leaked into the oil system, making the sludge problem worse. Repair costs were usually very high, and in some cases, owners chose to replace the entire engine rather than attempt repeated fixes.
Mechanics often describe the 2.7L V6 as difficult to service compared to other engines, which increases labor costs. Combined with the frequency of major failures, many drivers lost confidence in Chrysler vehicles equipped with this engine.
Although some owners who performed very strict oil change schedules managed to extend the life of the 2.7L V6, it still never reached the reliability levels of competing engines. Its record remains one of disappointment, as many people spent more money than expected to keep it running.
2. Volkswagen 3.6L VR6

One issue that shows up repeatedly is timing chain tensioner failure. When the tensioners wear out, the chains can slip, leading to misfires or complete engine damage if not repaired quickly. This is a common complaint among mechanics who have worked on Jaguar models from this period.
Oil leaks are another frequent problem. Valve cover gaskets and other seals tend to wear out early, leading to oil loss and potential engine damage if ignored. While leaks are common in older engines, the AJ-V6 often developed them sooner than expected.
Another complaint comes from the high cost of parts and labor. Since Jaguar vehicles are not as common in the United States as Japanese or American brands, sourcing parts takes more time and money. Many independent repair shops are not familiar with the engine, so owners often rely on specialized mechanics who charge higher rates.
While some drivers enjoyed the performance and smooth ride the AJ-V6 provided, those who planned to keep their vehicles for many years often grew frustrated with repair frequency and costs. The combination of timing chain concerns, leaks, and high maintenance expenses makes this engine one that struggles with longevity compared to other V6 options.
4. Hyundai 3.3L V6 (Lambda)
Hyundai has improved its engines in recent years, but the early versions of the 3.3L Lambda V6 did not always inspire confidence. This engine was used in models such as the Hyundai Sonata, Santa Fe, and Kia Sorento. While some owners enjoyed trouble-free service, others experienced issues that raised questions about its long-term dependability.
One area of concern was bearing wear, which sometimes led to knocking noises and eventual engine failure. In some cases, recalls and warranty extensions were issued to cover these problems. Owners who were unlucky enough to experience bearing failure outside warranty periods often faced costly repairs or complete replacements.
Oil consumption problems were also reported. While not as widespread as in some other engines, enough cases occurred to make drivers cautious. Keeping oil levels topped up became necessary for those who wanted to avoid damage.
Another challenge was the availability of parts in earlier years. Independent mechanics sometimes struggled to find affordable replacements, leading to higher costs. Although Hyundai has made improvements and later versions of the Lambda V6 are better, the early 3.3L units developed a reputation for being unpredictable.
For drivers who performed strict maintenance and paid close attention to oil changes, the engine sometimes lasted well past 150,000 miles. However, it did not consistently match the durability of Japanese V6 engines like those from Toyota or Honda. The uneven record of the early Lambda V6 makes it less trusted among people who want a car engine that will reliably last for many years.
