Annual or bi-annual vehicle inspections are a source of stress for many drivers, especially those with aging or high-mileage vehicles. These inspections, which can range from basic safety checks to complex emissions testing, are essential for ensuring that vehicles on the road are both environmentally compliant and mechanically sound.
For some, it’s a routine process that ends with a simple sticker on the windshield. For others, it becomes a frustrating (and expensive) ordeal involving multiple repair trips and retests. Whether you’re preparing for an upcoming inspection or considering a used car purchase, knowing which vehicles tend to pass with flying colors—and which tend to falter—can save you considerable time, money, and anxiety.
While every car’s ability to pass inspection depends heavily on maintenance history and how it’s been driven, certain models consistently outperform others when it comes to reliability, durability, and engineering design. Some vehicles seem tailor-made for inspection success: they have robust engines, simple but effective emissions systems, dependable electronics, and suspension setups that hold up well over time.
Others, however, present a litany of potential problems, from chronic check engine lights to worn-out suspension parts and aging emissions controls that no longer do their job. These vehicles might have once been top sellers or highly rated, but age, engineering flaws, or cost-cutting measures have now made them more of a liability than an asset when it comes to passing mandatory inspections.
This guide takes a deep dive into five cars that are highly likely to pass their next inspection—and five that are more likely to fail. The cars that shine during inspections tend to be well-engineered, consistent in performance, and easy to maintain. Their success isn’t necessarily tied to being luxurious or expensive, but rather to their reputation for dependability.
On the other hand, the vehicles that fail are usually those that are either too complex for their own good or those that suffer from poor build quality, rapid component wear, or overly sensitive diagnostic systems that trip false alarms and trigger unnecessary red flags.
It’s important to clarify: this article doesn’t aim to bash any particular brand or car owner. There are certainly well-maintained examples of the “bad” cars on this list that might pass inspections without issue, just as there are neglected “good” cars that could fail spectacularly.

5 Cars That Won’t Pass the Next Inspection
1. Volkswagen Passat (Older Models)
Older models of the Volkswagen Passat, especially those manufactured between the late 1990s and early 2010s, have a troubling track record when it comes to passing modern inspections. A significant reason for this is the complexity of their engine management systems, combined with the general aging of components.
Many Passats from this era used turbocharged engines, such as the 1.8T or the 2.0T, which are known to suffer from carbon buildup, vacuum leaks, and premature wear of timing components. These issues often manifest as check engine lights triggered by misfires or fuel mixture errors, both of which can result in immediate inspection failure.
Further complicating matters, these engines are notorious for oil leaks from gaskets and seals, which not only reduce reliability but also pose fire and environmental hazards that inspection stations take seriously.
Emissions systems are another critical area where the Passat tends to fall short. Volkswagen’s emissions control strategies in older models are known for being sensitive and fragile. Components like EGR valves, catalytic converters, and oxygen sensors often fail after 100,000 miles, and if they are not replaced with OEM-quality parts, emissions can skyrocket.
The notorious Dieselgate scandal, while not directly impacting gasoline versions of the Passat, has left a legacy of scrutiny on VW’s emission performance, leading to stricter testing and greater awareness from inspectors. Vehicles with partially disabled emissions systems—common when owners attempt DIY fixes—almost always fail emissions tests. And with VW parts and labor often being more expensive than average, many owners delay or ignore necessary repairs, making inspection failure even more likely.
Even beyond engine and emissions systems, the Passat struggles with electrical reliability. Older Passats often develop electrical gremlins in their window regulators, central locking systems, and dashboard electronics. Inspection stations check for working safety lights, airbag readiness, and functioning OBD ports, and any faults in these areas can lead to rejection.
Furthermore, suspension and steering components wear faster than expected, especially in climates with rough roads or winter salt exposure. Control arm bushings, CV joints, and tie rod ends can develop play or leaks, triggering failure under safety inspection protocols. In sum, unless meticulously maintained, older VW Passats are more likely to struggle under modern inspection standards than pass.
2. Jeep Grand Cherokee (Older Generations)
Older Jeep Grand Cherokees, particularly those produced between the mid-1990s and early 2010s, often struggle to pass inspections due to a combination of heavy-duty drivetrain wear, chronic suspension issues, and emissions problems. These SUVs were engineered with off-road capability in mind, which, while a benefit for utility, comes at a cost to long-term mechanical integrity.
Many owners use these vehicles in rugged environments or for towing, subjecting them to far more stress than the average family sedan. This wear and tear can cause extensive damage to drive shafts, differentials, and suspension components. By the time these vehicles are due for inspection, it’s not uncommon to find worn-out control arms, leaky ball joints, or damaged tie rods—all of which can easily cause failure during a safety evaluation.
One of the major red flags during inspection is engine-related trouble codes and high emissions output. Jeep’s older powertrains, such as the 4.0L inline-six or the 5.7L HEMI V8, are robust but not particularly fuel-efficient or clean-burning by modern standards.
These engines often develop exhaust leaks, inefficient combustion, or clogged catalytic converters over time. The oxygen sensors and EGR valves in older Grand Cherokees tend to wear out without throwing clear diagnostic codes until it’s too late, causing a spike in NOx or CO emissions during testing. Add to that the notorious unreliability of the check engine light in some models (which can be stuck on even after repairs), and it’s easy to see why these vehicles often get flagged in emissions testing stations.
In addition to mechanical issues, electronics and body control systems in the Grand Cherokee have historically been a source of frustration. Owners frequently report problems with dashboard illumination, ABS sensor failures, and malfunctioning brake lights—all of which are tested during inspection. The older Uconnect system in some trims is also prone to glitches, affecting not only the user experience but system alerts and vehicle monitoring as well.
Rust in the undercarriage, especially around the suspension mounting points and brake lines, is another recurring issue in northern climates, and inspectors are trained to fail vehicles with even small compromises to structural integrity. Overall, unless these Jeeps are pampered and preemptively maintained, they face an uphill battle when it’s time for inspection.
3. Ford Focus (First Generation)
The first-generation Ford Focus, released between 1998 and 2007 in various global markets, quickly gained popularity as an affordable, compact vehicle. However, as these vehicles age, their track record for passing inspections deteriorates sharply. One of the most consistent problems is related to the suspension system.
Early Focus models are particularly susceptible to wear in front struts, control arm bushings, and sway bar links. Over time, these parts degrade and produce clunks, squeaks, or loose steering feel—issues that inspection centers take seriously under safety testing. In colder regions, rust becomes an additional concern, especially in the suspension mounts and subframes, both of which are critical to a vehicle’s safety integrity and a common failure point during inspections.
Under the hood, the early Ford Focus engines are not without their share of inspection problems. These cars came with basic engine management systems that are now outdated by modern standards. The vehicle’s EGR systems, throttle bodies, and ignition coils often develop faults that lead to increased emissions and rough idling.
As the miles add up, oxygen sensors begin to fail, and catalytic converters can become clogged, especially in models that were not maintained with regular oil changes and air filter replacements. Combined with early-stage oil leaks from the valve cover or oil pan gasket, these issues can create a cocktail of emission failures during inspection, and fixing them can cost more than the vehicle is worth.
On the electronics front, the Focus is not much better. Owners often deal with malfunctioning dashboard lights, intermittent ABS warnings, and faulty lighting circuits. These electrical faults, while sometimes minor in daily driving, become major red flags during a vehicle inspection.
The onboard diagnostics systems in the first-gen Focus are also prone to communication errors with modern OBD-II readers, making it difficult for inspectors to verify emissions data even if the engine appears to be running smoothly.
With such a high potential for safety and emissions faults, combined with the low residual value of the vehicle, many Focus owners find that repairs to pass inspection are simply not economically feasible, leading to the vehicle being scrapped or sold for parts instead.
4. Dodge Charger (Older Models)
The Dodge Charger, especially models produced between 2006 and 2012, is a bold, powerful car with strong street presence, but it often falters when faced with modern inspection standards. The V6 and V8 engines, while delivering impressive performance, are susceptible to a range of problems that manifest during emissions and safety tests.
For instance, the 5.7L HEMI engine has a history of lifter failure, camshaft wear, and MDS (multi-displacement system) problems that trigger check engine lights and reduce engine efficiency. Emission control components like catalytic converters and EGR valves are also known to fail prematurely, especially on Chargers that have been driven aggressively. All these issues contribute to high hydrocarbon or NOx readings, which are an automatic inspection failure in many states.
The braking and suspension systems on older Chargers are another concern. These are heavy vehicles, and as such, their brake rotors, pads, and calipers are under constant strain. Premature rotor warping and uneven pad wear are common, and if not addressed, they affect stopping distances and pedal feel—two major points on any safety inspection.
Similarly, the rear-wheel-drive setup puts extra stress on control arms and bushings, leading to clunking sounds or excessive wheel play. These signs of wear are easy for an inspector to detect and will usually result in a fail unless thoroughly repaired. Even then, poor quality aftermarket parts or incorrect installations can trigger another round of failures.
Older Chargers also experience problems with electrical reliability. The TIPM (Totally Integrated Power Module), which controls many of the car’s functions, is notoriously failure-prone and can cause issues ranging from non-functioning headlights and windows to unpredictable stalling.
Additionally, the OBD-II system can be temperamental, giving inconsistent codes or failing to communicate properly with inspection systems. As these issues often go unresolved due to high repair costs, owners of aging Chargers find themselves faced with the prospect of pouring money into a vehicle that may still not meet inspection standards. Unless proactively maintained, these vehicles are a frequent source of inspection-related headaches.
5. Nissan Altima (Early 2000s Models)
The Nissan Altima models from the early 2000s—particularly those built between 2002 and 2006—have several critical flaws that make them poor candidates for passing modern inspections. One of the most significant issues is engine reliability. These Altimas often suffer from premature catalytic converter failure, excessive oil consumption, and failed oxygen sensors, all of which contribute to high emissions readings.
The 2.5L four-cylinder engine in particular is known to burn oil at an alarming rate after just 100,000 miles, which leads to smoky exhaust, fouled spark plugs, and clogged converters. Emission tests often detect elevated levels of hydrocarbons and carbon monoxide, automatically disqualifying the vehicle unless major repairs are done.
In terms of structural and mechanical integrity, early 2000s Altimas suffer from a variety of problems that are easily flagged during inspection. The suspension systems tend to wear quickly, particularly in the strut mounts and control arms, which develop play or begin to rust out.
This is especially prevalent in regions that use road salt in winter. Brake systems also show premature wear, with rotors warping and pads wearing unevenly—both of which affect braking performance and are critical components of the inspection process. Further compounding this is a tendency for early Altimas to develop steering issues, including loose tie rods or leaking power steering systems, any of which will show up during the physical safety check.
Additionally, early Altimas are plagued by electrical and diagnostic issues that further complicate their ability to pass inspection. Dash lights often fail, check engine lights remain on despite repairs, and body control modules become unreliable.
These problems can prevent even a relatively well-maintained Altima from passing an inspection simply because inspectors can’t trust the systems to give accurate diagnostics. In some cases, owners report that even after spending considerable money on repairs, the vehicle fails again due to new, unrelated issues cropping up. The result is a vehicle that, while inexpensive to buy, can be a financial liability when it comes time for mandatory inspections.

At the end of the day, a vehicle’s ability to pass inspection is about far more than its brand name or how good it looks in your driveway. It’s a reflection of sound engineering, quality manufacturing, and—perhaps most critically—how well the car has aged over time.
Cars that pass inspections consistently tend to share a common set of characteristics: reliable engines that burn cleanly, resilient suspension and braking components, and electronic systems that communicate clearly and accurately. They don’t just survive wear and tear; they’re designed to withstand it. When you drive a car that fits this mold, the inspection process becomes just another routine part of ownership, not a dreaded visit to the mechanic.
The vehicles that fail inspections, meanwhile, often suffer from a troubling blend of aging parts, neglected maintenance, and inherent design flaws. Whether it’s chronic electrical issues, worn suspension components, or outdated emissions systems, these weaknesses come to light when a trained inspector gives your car a hard look.
It’s not necessarily the driver’s fault—many of these problems are baked into the vehicle’s DNA. Still, it falls on the owner to manage the wear and try to stay ahead of the curve. Unfortunately, with certain vehicles, even the most attentive care may not be enough to consistently pass inspection once the miles start adding up.
That said, there’s a critical takeaway from all this: owning a vehicle that’s more likely to pass inspection doesn’t just mean fewer headaches—it often means lower ownership costs overall. Repairs for worn-out bushings, faulty sensors, and emissions-related components add up quickly.
Inspections act as a barometer of future reliability; if your car fails now, it’s likely giving you a preview of what’s ahead. Conversely, vehicles that pass with ease are often the ones that keep running strong with minimal intervention. They’re not only safer and cleaner, but they also provide peace of mind.
This doesn’t mean you need to rush out and trade in your vehicle if it made the “won’t pass” list. Many of those models can still provide good service with proactive maintenance, quality parts, and a reliable mechanic. The difference is, you’ll need to stay vigilant, plan for inspections, and be prepared for surprises.
If you’re buying a used vehicle, however, the insights from this list should weigh heavily into your decision. The cost of a slightly more expensive, but more inspection-friendly car, often pays off in reduced stress and long-term expenses.
Ultimately, vehicle inspections are a reminder that cars are more than just tools for transportation—they’re machines that demand care, attention, and a little foresight. Whether you’re a cautious planner or a last-minute problem-solver, knowing which cars tend to pass or fail can shape your entire ownership experience.
Choose wisely, maintain diligently, and you can make inspection day just another easy checkmark on your calendar, rather than a financial gamble.
