What breaks most on the 2005 Chevrolet Corvette
- Headlights60 complaintsmostly at 65,000–104,000 miles (105,000–167,000 km)
- Engine stalling21 complaintsmostly at 14,000–61,000 miles (23,000–98,000 km)
Specific parts named in the 538 owner complaints filed with NHTSA for the 2005 Chevrolet Corvette (all dates). Miles = the odometer owners typed in (middle half); cost = the repair bills owners wrote in those same complaints, in U.S. dollars. Owners' reports, not confirmed defects.
When problems show up
Most problems on this year showed up between 3,000 and 12,000 miles (4,800–20,000 km) (the middle half of the 56 complaints, of all 64 filed so far, that listed a mileage).
- At 60K, 100K and 150K miles (97K, 161K and 241K km) Past the range where most problems showed up: it has likely had them or dodged them, so repair records matter most.
This is when owners who had a problem reported it, not the odds that one car will have it.
Questions to ask the seller
- Were recalls 14V251000 (electrical), 10V172000 (steering) and 09V491000 (body structure) done? It has 6 recalls in all. Ask for the dealer printout, or check the VIN.
- Any rust or damage underneath, or doors and hatches that don't close right?
- Do all the lights, screens and power features work? Has the battery, alternator or any wiring been replaced?
- Any oil burning, leaks or check-engine lights? Ask for oil-change records.
- Chevy sent dealers 713 repair notes for this car. Was this one done: “Erratic or inoperative oil pressure gauge”?

How serious. Out of all 64 owner complaints filed so far (every year since it was sold, not just the first 3), owners reported:
“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.
Share of this year's owner complaints filed with NHTSA, not the share of cars that break. One complaint can name more than one area.

When owners reported problems. From owner complaints to the government.
Most owners who filed a complaint with NHTSA had 3K to 12K miles (5K to 20K km) on the car (56 of all 64 complaints filed so far listed the miles). This shows when people who had a problem reported it, not the odds that your car will have it.
In owners' words
2005 Corvette top delaminated and separated from car. It could have injured a pedestrian or caused another car to crash.

Is the 2005 Chevrolet Corvette reliable?
No, it is one of the worst by government complaints. It drew about 3 times the average car's complaints filed with NHTSA in its first 3 years, per car sold (Lemon Index 285; 100 is average, lower is better). The Chevrolet Corvette year with the fewest complaints per car sold since 2010 is 2021.
What are the most common 2005 Chevrolet Corvette problems?
In owner complaints to the government, the parts named most are body structure (47%), electrical (17%) and engine (14%). That is the share of complaints, not the share of cars that break.
How many recalls does the 2005 Chevrolet Corvette have?
6 safety recalls (latest: electrical). Recall repairs are free at any dealer; check a specific car's VIN at nhtsa.gov/recalls.
What gas mileage does the 2005 Chevrolet Corvette get?
19 mpg combined, depending on the engine (EPA estimate).
At what mileage do 2005 Chevrolet Corvette problems show up?
Most problems on this year showed up between 3,000 and 12,000 miles (4,800–20,000 km) (the middle half of the 56 complaints, of all 64 filed so far, that listed a mileage). At 60K, 100K and 150K miles, a 2005 is past the range where most problems showed up: it has likely had them or dodged them, so repair records matter most. This is when owners who had a problem reported it, not a prediction for one car.
Does the 2005 Chevrolet Corvette have transmission problems?
Transmission and drivetrain issues aren't among its top 5 complaint areas.
How much does the 2005 Chevrolet Corvette cost in fuel a year?
About $3,950 a year, by the EPA's current estimate.

What Chevrolet Corvette year is better than the 2005?

The Lemon Index counts owner complaints filed with the U.S. government (NHTSA) in a car's first 3 years, per car sold, against the average car of the same model years (100 = average, lower is better). It measures complaints, not crash safety. A complaint is an owner's report, not a confirmed defect. How it works
