The Aston Martin Vantage GT8, introduced as a lighter, race-inspired version of the Vantage in 2016, is revered for its raw driving experience and exclusivity, with only about 150 units produced. Equipped with a 4.7-liter V8, an aggressive aerodynamics package, and options for a manual or automatic transmission, the GT8 is an enticing choice for enthusiasts who prioritize performance and style. However, owning a car as rare and performance-focused as the Vantage GT8 does come with its own set of challenges, particularly in terms of common mechanical and maintenance issues.
In this article, we’ll dive into the most common problems encountered by Vantage GT8 owners, along with insights into buying considerations and expected ownership costs.
Common Problems with the 2016-Present Aston Martin Vantage GT8
1. Transmission Shifting Issues (Manual and Automatic)
The Vantage GT8 offers both manual and automatic transmission options, and each comes with its unique set of challenges. With the manual, drivers have reported issues such as:
Gearbox Notchiness: The manual transmission, while rewarding to drive, has been noted for feeling slightly "notchy" or rough when shifting, especially when cold. This issue often fades as the gearbox warms up but can still be a cause for concern for those seeking a smooth shift feel.
Automated Manual Transmission Problems: Owners of the automatic transmission (known as the Sportshift II) frequently report rough shifts, lagging responses, and sometimes unexpected jerks. The Sportshift is an automated manual and lacks the smoothness of a fully automatic transmission, which can make for an uncomfortable driving experience in urban or low-speed environments.
Resolution: For the manual, keeping the transmission fluid fresh can help reduce notchiness. However, in both cases, the only true remedy for significant issues with the Sportshift transmission is replacing worn internal components, a process that can be costly.
Repair Costs: Minor repairs or fluid changes generally cost $300-$600, while more intensive work on the Sportshift system can reach up to $5,000, depending on the severity and need for component replacements.
2. Clutch Wear and Replacement
The GT8’s performance orientation means that many owners drive it hard, which can lead to accelerated clutch wear. This issue is more pronounced in cars with the automated manual transmission, where the electronic clutch engagement system can be rough on the clutch over time. Symptoms of clutch wear include slipping gears, a burning smell, and increased difficulty shifting.
Resolution: Regularly inspecting the clutch system and replacing the clutch as soon as signs of wear are evident is recommended. Additionally, ensuring the clutch fluid is topped up and fresh can extend its life.
Repair Costs: Clutch replacement on the GT8 can cost between $3,000 and $6,000 due to the labor-intensive nature of the repair and the cost of high-performance parts.
3. Suspension and Bushings Wear
With the GT8’s stiff, track-tuned suspension setup, the suspension components can wear out more quickly, particularly if the car has been used on tracks or driven aggressively on poor roads. Symptoms of worn suspension parts include knocking sounds over bumps, a decrease in ride comfort, and uneven tire wear. Bushings, in particular, tend to degrade faster on this model due to the high performance load they endure.
Resolution: Regular suspension inspections and replacing worn bushings, control arms, and shock absorbers as needed. Aftermarket options can also provide improved durability.
Repair Costs: Suspension repairs, depending on what parts are needed, generally range from $800 for bushings alone to $4,000 for more comprehensive repairs, such as shock absorber replacements or control arm work.
4. Brake Rotor and Pad Wear
The GT8’s braking system is designed to handle high-speed stops, and while it’s effective, it also tends to wear out rotors and brake pads relatively quickly, especially if the car is driven aggressively. This can lead to reduced braking performance, squeaking sounds, and longer stopping distances if not addressed.
Resolution: Regularly inspect the brake pads and rotors for signs of wear, and replace them promptly to maintain optimal braking performance. For GT8s that see track use, upgrading to higher-performance or ceramic rotors may extend the lifespan of the braking system.
Repair Costs: Brake pads typically cost around $500 for a set, while rotor replacements can cost between $800 and $1,200. Full brake system replacement costs can reach $3,000 to $5,000, especially if performance-grade parts are used.
5. Cooling System Issues
The GT8’s V8 engine is high-strung, and the cooling system has to work hard to keep it operating at an optimal temperature, especially in hot climates or during track use. Over time, components like the radiator, coolant hoses, and water pump can wear out, leading to overheating issues. Signs of cooling system problems include rising engine temperatures, coolant leaks, and warning lights on the dashboard.
Resolution: Regular maintenance of the cooling system, including timely coolant flushes and inspections of hoses and the radiator, is essential to avoid overheating. Replacing worn or aging components preemptively can prevent significant engine damage.
Repair Costs: Radiator replacement costs range from $800 to $1,500, while other cooling components like hoses and the water pump can add an additional $300 to $1,000.
6. Exhaust System Corrosion
The GT8’s performance exhaust, while delivering an iconic sound, can be susceptible to corrosion, especially in regions with high humidity or exposure to salted roads. Corrosion in the exhaust system can lead to leaks, an increase in emissions, and loss of performance. In extreme cases, it may even cause failure in the exhaust components themselves.
Resolution: Regularly inspect the exhaust system for signs of corrosion or damage, particularly if the car is exposed to harsh environments. Some owners opt for aftermarket exhaust systems made from stainless steel or other corrosion-resistant materials to avoid this issue.
Repair Costs: Exhaust system repairs vary widely, with minor repairs costing around $300, while a full replacement can cost $2,000-$3,000, especially with performance parts.
What to Look For When Buying a 2016-Present Aston Martin Vantage GT8
When considering a used Vantage GT8, it’s crucial to obtain a detailed service history to ensure regular maintenance has been conducted, especially for high-performance components like the clutch, transmission, and cooling system. Look for signs of heavy track use, as this can accelerate wear on critical parts such as the suspension, brakes, and clutch. Ideally, try to obtain a pre-purchase inspection from an Aston Martin specialist to check for hidden issues.
Another important factor is to test both cold and warm shifts if the GT8 has the Sportshift transmission, as rough shifting is a common complaint with this system. Listen carefully for any suspension noises or braking squeaks, which may indicate worn parts.
How Expensive Is It to Own a 2016-Present Aston Martin Vantage GT8?
Owning a Vantage GT8 involves relatively high upkeep costs compared to many other luxury cars due to its performance-oriented nature and exclusivity. Here’s an estimate of ownership costs:
- Routine Maintenance: Oil changes, inspections, and fluid replacements cost approximately $500-$800 per visit.
- Annual Repair Budget: Due to the common issues outlined above, expect to set aside $2,000 to $4,000 annually for repairs.
- Insurance Costs: Insurance premiums for the GT8 can vary widely depending on location and driver profile, but generally range between $2,500 and $4,500 per year.
- Fuel Costs: The GT8’s V8 engine isn’t highly fuel-efficient, averaging around 15-18 mpg, meaning fuel costs will be a noticeable factor depending on usage.
Final Thoughts
The Aston Martin Vantage GT8 is an exceptional vehicle that provides an engaging, track-ready experience rare among luxury coupes. However, prospective owners should be prepared for the maintenance demands that come with a high-performance, limited-production car. By staying proactive with regular maintenance and addressing issues promptly, it’s possible to enjoy a rewarding ownership experience with the GT8. For those willing to invest in its upkeep, the GT8 remains a thrilling and head-turning model in the Aston Martin lineup.
