The Nissan Altima, introduced to the U.S. market in 1993, has long been a top contender in the midsize sedan segment. It quickly gained favor for its reliability, comfort, and affordability. Features like advanced safety systems and solid fuel efficiency made it a go-to choice for commuters and families. However, despite its popularity, some Altima model years fell short on quality, reliability, and satisfaction. Whether plagued by recurring mechanical issues or costly repairs, we delve into seven Nissan Altima years to avoid and explain why they’re best left off your shopping list.

2002 Nissan Altima: Rocky Third-Generation Start

The 2002 Altima was a game-changer in terms of design, offering more power and a roomier interior. Unfortunately, it was also plagued with critical engine issues. Many owners reported excessive oil consumption that often went unnoticed until the engine overheated or failed entirely. This was frequently attributed to poor piston ring design, which allowed oil to bypass the cylinders.

The National Highway Traffic Safety Administration (NHTSA) recorded numerous complaints about catastrophic engine damage, often requiring a costly full engine replacement. Adding to these woes were frequent reports of premature rust, particularly around the undercarriage and suspension components. This rust could lead to safety hazards, especially in regions with heavy road salt use. For these reasons, the 2002 Altima is best avoided by prospective buyers​.

2005 Nissan Altima: Catalytic Converter and Engine Failures

The 2005 Altima carried forward the design and mechanics of earlier years but was marred by severe reliability issues, primarily with the catalytic converter. Defective catalytic converters not only failed prematurely but also led to engine damage. This happened when the catalytic converter’s particles were sucked back into the engine, resulting in irreparable internal damage.

This issue often required both the catalytic converter and engine to be replaced, resulting in repair bills exceeding $5,000. Moreover, this defect typically manifested shortly after the warranty expired, leaving owners with limited options. The 2005 Altima also experienced frequent electrical issues, such as failing power windows and faulty instrument clusters, adding to owner frustrations​.

2013 Nissan Altima: Troubled CVT Debut

The 2013 Altima marked the start of its fifth generation and introduced significant updates, including Nissan’s now-infamous Continuously Variable Transmission (CVT). While the CVT was intended to improve fuel efficiency and smooth acceleration, it became a significant pain point for drivers. Common issues included delayed acceleration, overheating, and complete transmission failure. These failures often occurred between 60,000 and 80,000 miles, which is well before the expected lifespan of a transmission.

To address widespread complaints, Nissan extended the CVT warranty for the 2013 model. However, even with this measure, many owners found themselves dealing with repeated repairs and lingering doubts about the vehicle’s reliability. Beyond the transmission problems, 2013 Altimas were also criticized for poor build quality, including fragile interior materials prone to premature wear​. All told, it makes our list of Nissan Altima years to avoid.

2014 Nissan Altima: More of the Same CVT Woes

The 2014 Altima carried over many of the same issues as its predecessor, particularly regarding the CVT. Owners continued to report jerking and shuddering during acceleration, as well as complete transmission failures. Although the CVT’s extended warranty applied to this year as well, many drivers found the hassle of multiple dealership visits and ongoing repairs unbearable.

This model also faced electrical problems, such as malfunctioning power windows and unreliable sensors for key systems like airbags. These recurring issues further diminished driver satisfaction, making the 2014 Altima one of the least recommended years in the lineup​.

2016 Nissan Altima: Recalls and Recurring Issues

By 2016, Nissan had made efforts to address the CVT issues that plagued earlier models, but these efforts fell short. Complaints about transmission slipping and overheating continued, with some drivers noting that these problems made highway driving particularly stressful. The CVT’s tendency to enter “limp mode” during prolonged operation added another layer of frustration for owners.

Additionally, the 2016 Altima faced a significant recall for defective hood latches. This issue posed a serious safety risk, as hoods could unexpectedly open while the vehicle was in motion. While Nissan addressed this problem through free repairs, the combination of transmission and safety concerns tarnished the reputation of this model year​.

2018 Nissan Altima: Safety and Reliability Concerns

The 2018 Altima continued to struggle with long-standing CVT issues, though at a slightly lower frequency compared to earlier years. However, new problems emerged, including a recall for improperly installed rear door locks. According to NHTSA, the locks could fail to secure properly, leading to doors unintentionally opening while driving. This safety issue was particularly concerning for families with young children.

On the mechanical side, reports of excessive oil consumption began to resurface, evoking memories of the problematic 2002 model. Though these issues were not as widespread, they were severe enough to warrant caution. Combined with minor but annoying glitches in the infotainment system, the 2018 Altima left many drivers disappointed​. As such, it’s one of our Nissan Altima years to avoid.

2020 Nissan Altima: First-Year Problems

As one of the first years in the sixth generation, the 2020 Altima introduced exciting updates, including advanced driver-assistance systems and a turbocharged engine option. However, first-year production flaws became apparent as owners reported continued CVT issues, such as delayed acceleration and shuddering.

Additionally, new problems with the electronic systems emerged. Some drivers reported random resets of the infotainment system and unreliable operation of advanced safety features, including lane departure warnings and adaptive cruise control. While these issues may not seem as severe as transmission failures, they reflect a lack of refinement that buyers should consider​.
