The C4 Corvette may present with certain problems depending on the model year. This is mostly due to minor design flaws & lack of tuning, problems like faulty airbag warning lights, leaking fluids or head gasket problems may occur to your C4 Corvette. If you notice these types of problems, be sure to ask your C4 Corvette expert when they started occurring and how you can fix them yourself.

Most Common Problems With C4 Corvette

The C4 Corvette is one of the most sought-after cars on the market, and with that comes a fair amount of problems as well. Below we are mentioning a few of them, so that you can get a better idea of what you might be in for if you purchase this car-

Airbag Warning Lights 

The Corvette’s airbag light is supposed to turn on when there is a problem with the airbag sensor. This problem is usually caused by faulty wires or a worn-out airbag. The sensor is located under the driver’s seat, so you should check to see if the wires are worn or damaged.

Low Coolant Light

The low coolant light is supposed to turn on when the engine has a problem with the cooling system, which might be caused by either a leak in your radiator or thermostat. Most of these problems can be avoided if you check your car’s fluid levels regularly and have them serviced at least once per year.

The Engine Suddenly Stops

The engine might stop working due to a faulty ignition switch or connection. Most problems with the Corvette’s ignition can be fixed by having someone check and repair any loose connections in your car’s wiring system.

The Corvette engine may suddenly stop when the car runs low on gas too! This is a problem that can be solved by making sure your car always has a full tank of gas. Most people don’t realize how little gas their Corvette actually takes, so this is something else you should check regularly!

Head Gasket Leaks

The head gasket leaks are usually caused by a problem with the cylinder heads. The C4 Corvette engines from 1986 to 1991 has an aluminium head, which is thinner and more fragile than the C5’s all-steel head. The C4 engine from 1992 onward has a steel head, which is sturdier but will still leak oil if damaged or overheated.

Leaking Power Steering Fluid

The power steering fluid might drip onto the exhaust pipe, causing it to smoke when you turn your C4 Corvette. This is a very common problem and usually happens when the power steering pump leaks fluid while you turn your wheels, so it’s a good idea to have someone check this if you notice any smoke while driving.

“The C4 is the best looking Corvette made in my opinion. The C5 with its awkward angles that look like it would cut you if touched, and the C6 with its hideous grill really don’t compare to the C4’s classic look. I’ve had my C4 for almost 20 years and it really is one of the most reliable cars I have ever owned.”

“I recently bought a C4 Corvette from a dealership that was originally from Chicago, but just opened in Florida. The car has been great so far and feels pretty much like a C5 Corvette when driving. I love C4 Corvettes and their C4 Cores!”

“The C4 Corvette is definitely my favourite Corvette model, even though I also like C3 Corvettes. The C4 has the C3’s lines but with a C5 engine and C6 brakes. It looks great when modified too!”
