Buyer analysis
KIA Optima or Toyota Camry: which should you buy?
The Toyota Camry has significantly fewer complaints per year (214 vs. 607) and fewer recalls (31 vs. 41), indicating a generally more reliable ownership experience. While both have serious issues, the Camry's lower frequency of problems suggests it may be a safer bet for a used car buyer.
Key differences
- The Kia Optima has nearly three times the annual complaint rate of the Camry, with engine failures being the most prevalent issue.
- The Camry's complaints are more evenly distributed, but include serious safety concerns like sudden acceleration and brake failure.
- The Optima has more recalls (41 vs. 31), including ones for forward collision avoidance and fuel system issues.
- The Camry's transmission problems are notable, but the Optima's engine oil loss and power loss are more frequent and severe.
- Check for any signs of engine oil loss or leaks, and review maintenance records for oil consumption issues.
- Look for any pending or unresolved recalls, especially those related to the engine or fuel system.
- Test the brakes thoroughly, especially on inclines, and listen for any unusual transmission noises during a test drive.
- Check if the vehicle has any open recalls, particularly for airbags or seats, and ensure they have been addressed.
Before you buy
- Obtain a vehicle history report and check for any reported accidents or previous engine/transmission work.
- Have a trusted mechanic perform a pre-purchase inspection, focusing on the engine, transmission, and brakes.
- Verify that all recalls have been completed by checking the VIN on the NHTSA website.
- Take the car for an extended test drive, including highway and stop-and-go traffic, to feel for any hesitation or unusual noises.
- Ask for maintenance records to ensure regular oil changes and other services were performed.
