If you are the owner of a 2017 to 2021 Chevrolet Corvette and you have taken your vehicle to a Chevrolet dealership multiple times for warranty repairs, please call or email us to see if we can assist you with a lemon law case. It is always better to speak with a lemon law attorney before you contact the automobile manufacturer on your own as lemon law attorneys can almost always negotiate a better deal for you than you can obtain on your own.
Seventh Generation Corvettes came equipped from Chevrolet with a 455HP/460LB 6.2 liter LT-2 engine, and an 8 speed GM 8L90 automatic transmission with paddle shift. Starting in 2020, GM released the C8 which comes standard with a 490HP/470LB 6.2 Liter LT-2 Engine and an 8 speed Tremec TR-9080 DCT (Dual Clutch Transmission). These high performance engines and transmissions may fail, even under normal driving conditions, potentially impacting the long term value of your car. With enough engine repairs under the factory warranty, your car may qualify for California’s Lemon Law assistance.
Common Corvette Engine Problems
Clunking or grinding sound
Some engine issues can be detected early on by identifying either a clunking, or grinding sound. Ordinarily a grinding noise can be attributed to a part with bearings that are worn out. These parts include water pumps, power steering pumps, alternators, and A/C compressors. Chevrolet Corvettes have been known to consume these parts during the warranty period. Do not wait for the problem to get worse. Bring your car to the dealership immediately for warranty repairs.
A ticking sound similar to the sound opening and closing a ball-point pen may be heard under the hood, either at idle or under acceleration. Usually, this is a symptom of low engine oil, or low engine oil pressure, but may also be, worn or broken valve springs, worn wrist pins, or an exhaust leak. Do not wait for the problem to get worse. Bring your car to the dealership immediately for warranty repairs.
Low Oil Light:
The ticking sound described above may be accompanied by a low oil light. A low oil light at idle may mean that either the oil pressure is low, or there is not enough oil in the engine reservoir. Either way, bring your car in to the dealership, and make sure the dealer not only adds additional oil, but performs an engine oil consumption test. This test will require you bring the car back in 1000 miles and oil consumption levels can be calculated.
Engine Misfire / Rough Idle:
There are several reasons why your engine may have a rough idle, or accelerate roughly. Your Corvette’s Lt-2 engine has coil packs that occasionally fail. This can lead to engine misfires, causing a rough idle, poor acceleration, and poor fuel economy. Rough idles and misfires may be accompanied by a Check Engine Light. Other causes of a rough idle or misfire could be a failed fuel pump, fuel leak, or clogged fuel line. Do not wait for the problem to get worse. Bring your car to the dealership immediately for warranty repairs.
Fluid Dripping Underneath the Car:
Be sure to check the garage floor, or parking space for fluid leaks. Corvettes have been known to leak engine oil, engine coolant, transmission fluid, and even gasoline on occasion. If your car is leaking fluids, bring the car to the dealership immediately.
Common Corvette Transmission Problems
Engine Revs but car not moving:
Your Corvette may have problems that prevent the transmission from engaging. When you press the gas, the car may rev but it does not immediately go into gear. This can be a result of a defective torque converter, low transmission fluid, or internal transmission failure. Do not wait for the problem to get worse. Bring your car to the dealership immediately for warranty repairs.
Transmission struggles to find a gear:
Your Corvette may have problems selecting or staying in gear. This could also be due to a transmission fluid leak, loss of communications to the TCM or computer. In some instances, this hard shifting may be accompanied by a burning smell and a humming noise coming from the transmission housing. This may be evidence of worn bearings, low transmission fluid quality, or worn internal gears. Please, bring the car to the dealership immediately for repairs, and save all correspondence with the dealer.
Other Problems That Could Make the C7/C8 Corvette a Lemon
- Loss of Power
- Check Engine Light
- Excessive Vibrations
- Compressor Failures
- No Start
- Leaky Convertible or Removable top
- Adjustable Suspension System Failures
- Cooling System Leaks
- Excessive Brake Wear or Warped Rotors
Repairs Taking over 30 days:
Repairs taking longer than 1 week were relatively rare before 2020. Since the outbreak of COVID-19, our clients are experiencing much longer repair times in the dealership, and less appointment availability for repairs and maintenance at the dealership. Much of this can be attributed to GM’s inability to secure microprocessor chips and other parts in their supply chain. There are very few complete engines or transmissions in GM’s parts inventory. For this reason, GM is refusing to replace complete engines or transmissions, even when recommended by dealership personnel. Instead, GM is opting to replace one bank of an engine at a time, or certain components of an engine or transmission, and then instructing the dealer to test drive the vehicle, run diagnostic tests, and return to the customer. In many cases these engines are failing again within the next few days.

Some of our clients have had multiple complaints open with GM over an intermittent problem. Intermittent problems are much harder for the dealer to diagnose, and repair. It is not uncommon for the dealership to not attempt to troubleshoot intermittent problems or may try to explain away your concerns by blaming the issue on your driving style or poor quality gasoline in the tank. In these instances, we recommend you ask the shop foreman to go on a ‘test drive’ with you so that you can point out the issue when it arises. You may also ask the dealership to temporarily install a ‘flight data recorder’ to record intermittent computer trouble codes that may not be in your computer’s cache by the time the car is returned to the dealership.

Lemon Law Case Checklist
- Remember to bring your car to the dealership as soon as a problem is detected, and to ask that the car not be returned until the problem has been repaired.
- When picking up the car from the dealership, make sure to verify that the repair invoice accurately reflects the actual dates, times, and work performed.
- Save all repair invoices. If you think you may be missing a repair invoice, ask for duplicates from the cashier, while at the dealership.
- The strength of a lemon law case is determined both by how many times your car was brought to the dealership for each issue, and how long the car has spent in the dealership. Do not let the dealership try and convince you that a serious problem is ‘normal’ and that there is no reason to bring the car back for further repairs if the problem persists.
- You do not have to bring your car back to the same dealership where it was purchased. If you feel you are not getting good service, or that your home dealership is not taking your concerns seriously, please take the car to another dealership. Many times a new dealership will try and win your loyalty by being extra helpful.
- Please do not leave your repair invoices or purchase contract in the car. If all of your paperwork is stored in a file in you home or office, we can evaluate the case even while the car is in the dealership.
