The Smart ForTwo from the 2007-2012 generation is known for its small footprint, impressive fuel efficiency, and ease of maneuverability, especially in urban settings. While this ultra-compact city car has a unique appeal, it does have some known issues and challenges that can affect its long-term reliability and performance. This article delves into the most common problems of the 2007-2012 Smart ForTwo, offers advice on what to look for when buying one, and outlines the overall cost of ownership.
Common Problems with the 2007-2012 Smart ForTwo
1. Transmission Jerking and Slow Shifts
One of the most frequently reported issues with the 2007-2012 Smart ForTwo is its automated manual transmission, which is known to be jerky and slow, particularly during gear changes. This unique transmission is neither a traditional automatic nor a manual but an automated system that performs the clutch action itself. Many drivers experience a noticeable “lurching” sensation during gear shifts, especially in lower gears or when accelerating slowly.
Symptoms and Solutions: Drivers may notice abrupt jerks, hesitations, or delays when shifting between first and second gear. Unfortunately, there’s no permanent fix for this quirk, as it’s largely a design limitation. However, learning to ease off the accelerator slightly when shifting can help smooth out the transitions. Regular software updates from a Smart dealership may also help improve the transmission’s responsiveness.
2. Premature Clutch Wear
Related to the transmission issues, clutch wear is common on the 2007-2012 ForTwo, especially in vehicles used primarily in stop-and-go traffic. Since the automated manual transmission controls the clutch electronically, clutch engagement can be more frequent and aggressive than in a traditional manual, leading to premature wear.
Symptoms and Solutions: Symptoms of clutch wear include difficulty accelerating, increased revving without corresponding power, or shuddering during gear changes. Unfortunately, clutch replacement can be costly, often exceeding $1,000 due to the labor-intensive nature of the repair. Prospective buyers should check if the clutch has been replaced in higher-mileage models.
3. Engine Oil Consumption and Leaks
Another common issue for the Smart ForTwo is oil consumption and oil leaks. Some engines in this generation tend to consume oil at higher-than-average rates, leading to frequent top-offs and potentially even engine damage if oil levels are not closely monitored. Additionally, leaks are common from areas like the valve cover gasket, which can deteriorate over time.
Symptoms and Solutions: If you notice blue smoke from the exhaust, an oily smell, or visible leaks underneath the car, it may indicate excessive oil consumption or a leak. Checking the oil level frequently is essential, as running low can lead to severe engine damage. Replacing the valve cover gasket may solve leaking issues, while staying vigilant about oil changes and monitoring levels can help manage consumption.
4. Battery and Electrical Problems
Electrical issues can crop up in the Smart ForTwo, particularly related to the battery and associated electrical components. Many drivers report frequent battery drain, even when the vehicle is parked. This is often attributed to the small battery size and power draw from accessories or aftermarket additions. Additionally, the alternator and starter motor can wear out more quickly than in larger vehicles.
Symptoms and Solutions: Common symptoms include difficulty starting, dimming lights, or frequent jump starts. Battery issues are more prevalent in cold climates, where the car may require a battery with a higher cold-cranking amperage. Using a battery tender can help prolong battery life, especially if the car is not driven regularly.
5. Exhaust System Corrosion
Due to the Smart ForTwo’s compact design, the exhaust system is exposed to road elements, which can lead to corrosion over time. This is especially common in areas with harsh winters where salt is used on the roads. Exhaust rust can lead to leaks or noise issues, as well as a reduction in fuel efficiency.
Symptoms and Solutions: Symptoms include rattling noises, reduced engine performance, or a louder exhaust sound. If you’re purchasing a Smart ForTwo in a colder climate, thoroughly inspect the exhaust system for rust and leaks. Replacing exhaust components can be expensive, so regular washing to remove salt in winter is recommended.
6. Suspension and Braking System Wear
While the Smart ForTwo is a lightweight vehicle, the suspension system is still subject to wear, particularly if the car has been driven extensively on rough roads or is used in urban environments with frequent stops and starts. Additionally, the small brake components can wear quickly, and the car’s stopping power may diminish if maintenance is not regularly performed.
Symptoms and Solutions: Symptoms of suspension wear include clunking noises over bumps, reduced stability, and uneven tire wear. For brakes, look out for squeaking, grinding, or decreased stopping power. Replacing suspension components like bushings and shock absorbers, as well as brake pads and rotors, may be necessary with high-mileage models.
7. Cooling System and Thermostat Issues
Cooling system issues, particularly related to the thermostat, are fairly common in the 2007-2012 Smart ForTwo. The thermostat may fail or get stuck, causing the engine to overheat or run at an incorrect temperature, which can lead to performance issues and potentially even engine damage.
Symptoms and Solutions: Symptoms of thermostat issues include fluctuating temperature gauge readings, overheating, or the engine running unusually cool. A faulty thermostat should be replaced as soon as possible, as it can lead to more serious overheating issues. Regular coolant checks and timely coolant flushes can help maintain the health of the cooling system.
Buying Tips: What to Look for in a 2007-2012 Smart ForTwo
Transmission and Clutch Check: Test-drive the car and pay close attention to how the transmission feels, especially during low-speed gear shifts. Any jerking or hesitation may indicate clutch wear or transmission software issues, which could lead to costly repairs.
Inspect for Oil Leaks: Check for visible oil leaks beneath the car or around the engine bay. Verify the service history to ensure regular oil changes, as low oil levels can lead to engine damage.
Electrical System Health: Test the battery and make sure the car starts easily. Look for signs of electrical issues, like flickering lights or dash warnings, and confirm the battery is in good condition.
Examine the Exhaust and Underbody: Look underneath the car for signs of rust, especially on the exhaust system. Corrosion in these areas is common, particularly if the car has been exposed to road salt.
Cooling System Check: Ask about any recent work on the thermostat or cooling system, as overheating is a known issue. Ensure that the coolant level is full and that the engine temperature remains stable during the test drive.
Cost of Ownership: Is the 2007-2012 Smart ForTwo Expensive to Own?
Fuel Efficiency
The Smart ForTwo is renowned for its fuel efficiency, with an average consumption of around 40-50 MPG, depending on driving conditions. For urban commuting, this car is highly economical on fuel, though longer trips may show less efficiency.
Maintenance and Repairs
Routine maintenance for the Smart ForTwo is generally affordable, covering basics like oil changes, air filters, and brake inspections. However, certain repairs, such as clutch replacement, exhaust work, or electrical repairs, can become expensive due to the compact design and specialized parts.
Insurance and Depreciation
Insurance costs for the Smart ForTwo are typically low, as it is a small, city-focused car with a low power output. Depreciation, however, can be significant, especially as the car ages, so it’s wise to buy a used model at a reasonable price rather than expecting high resale value.
Potential Extra Costs
Extra costs may arise from battery replacements, especially if the car isn’t driven regularly. Additionally, city-dwellers might consider upgrading to a more robust battery or investing in a battery tender to prolong battery life.
Conclusion
The 2007-2012 Smart ForTwo is a compact, efficient city car with a unique charm. However, it’s important to understand its limitations, from transmission quirks and clutch wear to common oil leaks and electrical issues. With regular maintenance and an understanding of its idiosyncrasies, the Smart ForTwo can serve as a reliable, economical vehicle for city driving.
