Chevrolet launched C7 Corvette in 2014, which continued until 2019. Some of its variants have many problems. It is a sports car with a 6.2L V8 and horsepower of 455 hp.
What C7 Corvette Years to Avoid? According to our research, many drivers avoid the 2015 and 2016 C7 Corvette because they have transmission problems, engine defects, reduced tire stability, malfunctioning modules, rough driving at top speed, electrical faults, and malfunctioning exhaust.
The sports car has different variants with appealing properties. I avoid its few models because they have significant engine defects.
Which C7 Corvette years to avoid?
Chevrolet C7 Corvette has various models with different internal defects. However, its few models are worst with different mechanical and electrical issues.
You can avoid its 2015 variants because it has significant transmission failures. Reduced gear efficiency affects the vehicle speed, and you cannot increase acceleration according to your convenience.
The car transmission fails and triggers other mechanical faults inside this model. Also, the malfunctioning gearbox affects the acceleration and driving stability.
In such circumstances, the car undergoes several vibrations when you increase the speed. You cannot stabilize it at higher acceleration because vibrations reduce driving stability and comfort.
2015 model undergoes excessive shaking at top speeds, which causes several mechanical defects inside the car. Overheating of the engine and other components are significant faults of this model.
You cannot select it because it undergoes high-temperature conditions, which reduce the stability of different electrical components.
The car computer malfunctions, and the internal data resets without a sign. The faulty transmission reduces the gear shifting and results in rough driving which is dangerous for drivers and travelers.
You should not buy the 2016 C7 Corvette because its engine has different defects. The transmission malfunctions without showing a significant symptom.
The engine fails and cannot provide the horsepower for ignition and other functions. The engine loses the lubrication fluids, which increases the friction level.
As a result, the engine produces loud grinding noises, which reduces the driving focus. The temperature increases from the standard level, which damages the engine and pistons.
You cannot select its 2016 model because its transmission has reduced stability. Furthermore, gear shifting is challenging because the transmission fluid leaks and increases internal friction. 2016 models have electrical faults and the exhaust system malfunctions.
It increases the emissions, and the fuel level decreases fast. The fuel system loses its efficiency suddenly and reduces the fuel economy.
Its 2017 model has a few problems of components damages, transmission defects, and rough driving. However, its cooling system malfunctions and the interior has less advanced amenities.
Why would you avoid C7 Corvette?
I avoid its 2015 and 2016 models because they have several defects.
Reduced transmission efficiency
A few models of the C7 Corvette have transmission slippage faults. The gearbox loses efficiency, and you cannot shift the gears properly.
Furthermore, the gearbox is not reliable in these models. It does not perform at a standard efficiency level.
Also, it is not durable and undergoes excessive slippage, which affects speed. These models have malfunctioning clutch speeds.
The clutch slips and increases the number of vibrations. Moreover, car stalling increases which affects the driving conditions.
You cannot stabilize the vehicle and its wheels on the road when the clutch undergoes slippage. The malfunctioning clutch and transmission affect the acceleration system.
It reduces the efficiency of the brake system, and you cannot stabilize the car at high speeds, which is dangerous. Sudden damage to mechanical parts leads to various crashes.
Engine defects
C7 Corvette has a few models with significant engine defects. Therefore, you cannot select these models because their engine failures affect their performance.
Malfunctioning head gaskets lead to fluid leaks and broken seals. In such circumstances, the engine malfunctions and cannot deliver sufficient power.
The engine cylinder malfunctions and reduces the efficiency of the variable valve timing chain.
Leakage increases, which enhances internal engine friction and reduces the performance of crankshaft, camshaft, and pistons.
Also, the engine requires more repair and maintenance, which increases the service cost. Their repair can cost is high according to the defect and engine condition.
A malfunctioning engine is dangerous because it can reduce car performance. Its sudden failure can affect the brake system and steering wheel performance.
Reduced tires stability
The defective tires and their reduced stability are one of the most significant defects of C7 Corvette models. Also, the tires lose their pressure and flats.
Their standard inflation range is 35 PSI (pounds per square inch). The tire pressure reduces from this range which decreases its stability and efficiency.
In such circumstances, the wheels lose their performance and undergo cracks. It affects the overall mileage, and frame momentum reduces on stable roads.
Unusual crashes and collisions increase when the wheels lose their standard pressure. The reduced pressure is a significant defect that affects vehicle momentum and leads to accidents.
Malfunctioning module
C7 Corvette is a computer-regulated sports car with efficient performance at high speed. However, this computer is a specific module that regulates the efficiency of vehicle components.
But, the module malfunctions due to internal circuit failure and loose connectors. In such circumstances, the module cannot protect the internal stored information.
The data reset, and the vehicle loses the standard information for its performance. It is dangerous and leads to severe accidental conditions.
The engine loses its torque and stability when the module malfunctions. Therefore, you cannot select its 2015 and 2016 models because they have module-related defects.
Rough driving at top speed
C7 Corvette is a sports car that requires maximum stability at high speeds. However, it is few models do not remain stable at high-speed levels.
In such circumstances, the driving becomes rough, and you cannot control the steering wheel. The mechanical defects reduce the tire momentum, and the frame loses its balance on smooth surfaces.
Rough driving is dangerous because sports cars require more momentum according to their frame. It is difficult, and you cannot handle the car at different accelerations.
Electrical defects
A few models of the C7 Corvette have several electrical defects. Their battery malfunctions due to broken terminals.
The current flow changes, which reduces the performance of connected wires and other connectors. The loose cables reduce the power flow to different parts.
The wire loses its efficiency when the circuit undergoes failures. The poor and loose connection decreases the current flow and stability.
Sometimes, the high voltage flows through the circuit, which decreases the efficiency of connected components. The battery malfunctions and cannot provide standard power for the optimized engine and vehicle efficiency.
Malfunctioning exhaust
A few of its models have malfunctioning exhaust systems, which increases emissions. It directly affects the fuel level inside the car.
The vehicle mileage of the vehicle varies when the exhaust system malfunctions because it increases the emissions rate. The catalytic converters lose their efficiency and require replacement.
In addition, the catalytic converter exposes to the external environment, and air pollutants affect their efficiency. Also, the exhaust manifold malfunctions and undergoes various cracks.
The higher emissions reduce the car’s fuel economy, and you cannot increase its speed according to convenience.
When does C7 Corvette have more problems?
It is a reliable and high-performance sports car. But, consumers complain about its 2015 and 2016 models because they have transmission failures and module defects.
However, the standard lifespan of this car is about 155000 to 220000 miles. The Chevrolet C7 Corvette has significant internal failures after 120000 miles.
It undergoes engine heating, excessive vibrations, and reduced momentum problems. Also, the defects increase when the mileage improves from the standard level.
Sometimes, a few models undergo failures at around 110000 miles due to low maintenance and high-speed driving. The driving style, road conditions, and component stability determine its life expectancy without significant failures.
