10 Cool Cars From The Early 2000s That Are Notoriously Unreliable

Amid the revolutionary advancements of the early 2000s, some automakers built stunning cars with one major caveat; poor reliability.

The automotive nostalgia of the 1990s is a potent force in the skyrocketing prices for used cars from that decade. As a result, more enthusiasts are shifting demand to the landmark cars from the early 2000s that ushered in the 21st century. Besides styling, the vastly innovative 2000s witnessed revolutionary advancements such as the dual-clutch transmission, advanced turbocharging, tire pressure monitor, GPS navigation, radar-based cruise control, and rearview cameras.

However, while some automakers gambled and made giant leaps forward into the new millennium, others were slow to change their approach. These shifts came with colossal automotive failures with bad engines, clunky transmissions, and awful build quality. If you're not wary of the reliability shortcomings of these seemingly cool cars, you might shoot yourself in the foot.

Nissan built the third-generation Altima on the FF-L platform, a unique chassis designated for the North American market without an equivalent model in Japan. Produced from 2002 through 2006, the third-generation Nissan Altima was the first to offer a 3.5-liter V6 in addition to the standard 2.5-liter four-cylinder engine.

Unfortunately for Nissan, the 2002 and 2003 Altima models suffer from prematurely rusting floorboards, leading to numerous complaints and a class-action lawsuit. Furthermore, the first two years of the third-generation Altima are prone to catalytic converter failure, excessive oil consumption, fuel pump issues, and exhaust system complications.

The iconic Cadillac DeVille earned its stripes as one of the longest-running nameplates in General Motors' history, spanning an impressive eight generations since 1958. Unfortunately, the last generation DeVille was an injustice to the model's long-standing legacy as a pioneer of styling and luxury.

The 2001 iteration is notably one of the most unreliable model years for the Cadillac DeVille, recording 51 complaints involving the powertrain, interior accessories, windshields, electrical, and cooling systems. The DeVille's problematic powertrain is prone to oil leaks, crankshaft position sensor failure, engine overheating, misfire from ignition coil failure, and excessive engine oil consumption.

Chrysler produced the mid-size Sebring in sedan, coupe, and convertibles body styles. Regardless of configuration, the Sebring appealed to the majority with its incredible design language, but significant problems with the 2.7-liter engine made it a bitter-sweet proposition.

From 2001 to 2005, the Sebring had chronic problems with oil leaks that created engine sludge and caused complete engine failure. Unfortunately, this frustrating problem accumulates over time, eventually leading to expensive repairs.

The stylish Solstice was one of Pontiac's swan songs, a rushed production model that ultimately failed to live up to its good looks. Engine options included a 177-hp 2.4-liter Ecotec LE5 inline-four and a 260-hp 2.0-liter turbocharged inline-four fitted in the GXP version.

Unfortunately, an ignition switch defect makes the Solstice an unreliable car prone to all sorts of hazardous situations. Besides complete airbag deactivation and sudden loss of power, the Pontiac Solstice has a one-piece cast iron header in the engine bay prone to rust and cracking, leading to annoying sounds and exhaust fume leaks.

Chevrolet has had several misses over the years, but very few models missed the mark and barely made an impact the same way the Cobalt did. The shockingly average Cobalt was available with a 145-hp 2.2-liter four-cylinder, while the SS performance model boasted a 203-hp 2.0-liter engine that Chevrolet later upgraded to 260 hp.

Due to the alarming number of complaints and recalls issued between 2005 and 2008, it's unsurprising that the Chevrolet Cobalt bears tags such as 'avoid like the plague' and 'beware of the clunker.' The most significant issues are the hazardous ignition switch and electrical power steering system failure, sometimes causing stiff steering that won't turn in any direction. Other reliability concerns include keys getting stuck in ignitions and roof structure issues.

The re-launched Charger got some flak from purists for abandoning the two-door muscle configuration that defined the iconic Dodge Chargers of the late 1960s. Although the rear-drive LX platform failed to pay homage to the Charger's origins, the beefy V8 engine configurations and wide range of personalization options reeled in some loyal enthusiasts.

Nonetheless, the resurrection was not without hiccups, with several problems reported between 2006 and 2008. In what is arguably the worst period for the Dodge Charger in terms of reliability, common issues include premature engine failure, faulty airbags, premature wear and tear on the suspension system, sticky gear shifts, electrical problems with the ignition, alternator failure, and brake issues.

The Touareg was one of the first in its segment, marginally embraced by enthusiasts for its impressive styling, remarkable capability, and stellar performance. However, the first-generation Volkswagen Touareg received the most complaints, with the 2005 and 2007 model year cited as the absolute worst.

Owners experience problems with engine rattles, engine misfires, oil leaks, faulty drivetrains, turbo complications, and premature brake pad wear. Furthermore, the Touareg has an abysmal rating regarding the average repair price for these common issues.

The Explorer is one of Ford's longest-running models, revered as one of the first modern SUVs to hit the market. The third-generation Explorer famously ditched the two-door configuration used in previous model years, adopted a rear-wheel drive platform, and incorporated an independent rear suspension.

However, early models of this generation of the Explorer also received the highest number of complaints since the model's debut, primarily thanks to the notoriously unreliable 5R55 automatic transmission series. Other glaring concerns involve body and paint problems, loose interior accessories, and engine rattles due to worn timing chain cassettes.

Unknown to some, the sensational design, refinement, and elegance of the Alfa Romeo 156 saved the brand from the brink of oblivion. The lusty engine options may have elevated the Alfa Romeo 156 appeal to more than just a pretty face, but the model is not without its fair share of problems.

The high-performance engines are prone to turbo and timing belt problems, while the sheer weight of the powertrain catalyzes front axle and suspension failure. Over time, Alfa Romeo 156 owners also reported difficulties with faulty radiators, thermostat failure, and loose airbag connectors.

The X-Type broke several barriers for Jaguar. It was the brand's first AWD production car and, in essence, its first FWD, not to mention it challenged the BMW 3 Series hegemony in the luxury sedan segment. However, critics despised the X-Type's cheapish Ford Mondeo underpinnings, a blemish in the noble and imperial Jag status.

Mixed reviews aside, early X-Type model years between 2001 and 2002 have serious build quality issues, from the interior to the drivetrain and down to the wheel hubs. If that doesn't put you off, the outrageous maintenance expenses for the Jaguar X-Type are a bottomless pit toward financial ruin.
