The picture
Is the KIA Optima or Chevrolet Silverado more reliable?
A plain-English read on what the NHTSA record says about living with each vehicle.
KIA Optima
The Kia Optima is a mid-size sedan that has averaged about 609 complaints per year over the past decade, with engine problems dominating the reports. Owners frequently describe sudden oil loss, engine knocking, and power loss, often despite regular maintenance. There are also notable complaints about electrical glitches and steering issues, and the model has 41 recalls covering items like forward collision avoidance and hybrid propulsion. Overall, the data suggests that living with an Optima requires vigilance about oil levels and engine health.
Chevrolet Silverado
The Chevrolet Silverado is a full-size pickup that has generated about 823 complaints per year, with engine and power train issues being the most common. Owners report severe problems such as engines shutting off while driving, transmission failures, and braking loss, sometimes on very new trucks. With 101 recalls, including fuel pump and forward collision warning defects, the Silverado's reliability picture is complicated by a high volume of both complaints and safety actions. Buyers should be aware that many reported failures occur at low mileage.

- 05SERVICE BRAKES455
Owners report sudden and excessive oil consumption with no visible leaks, leading to engine damage and stalling. One complaint describes a 2020 Optima that ran out of oil despite regular changes, causing power loss. This matters because engine failure can be costly and dangerous.
Complaints include oil level warnings and electrical glitches that may be linked to engine management. A 2020 owner reported losing oil excessively while also dealing with electrical issues. These problems can lead to unexpected breakdowns and expensive diagnostics.
With 720 complaints, steering issues are a top concern. Owners describe difficulty steering or unusual noises, which can affect control. This is critical for safety and often requires immediate repair.
There are 455 brake-related complaints, including premature wear or failure. Owners report reduced braking performance, which increases stopping distances. Brake problems are a major safety risk and should be inspected before purchase.
“Out of town July 12th 2025 my 2020 Kia Optima engine started having problems. I tried to get to my hotel but it was obvious I was not going to make it. I pulled into the nearest station and was told my car had no oil. There were no signs of leaking oil and no…”
“I have kept up on regular oil changes and maintenance on my Kia which I bought new 5 years ago. My issues started when my car's orange check engine light came on, I experienced loss of power such as difficulty accelerating even at low speeds, especially up hi…”

Owners report engines shutting off while driving, often with messages like 'Return to Neutral' and 'Press Start.' A 2026 Silverado with the 6.2L motor had a severe engine issue shortly after purchase. These failures can leave drivers stranded and are dangerous.
Transmission problems are common, including sudden shifting into neutral and loss of power. One owner reported a 2026 Silverado with less than 300 miles going into neutral on a hill. This can cause loss of control and is a major reliability concern.
Complaints include sudden loss of braking and engine shutdowns linked to electrical faults. A 2026 owner described the brake pedal remaining firm but braking effectiveness dropping. Electrical gremlins can disable critical safety systems.
Owners report severe loss of braking, sometimes with a firm pedal but no stopping power. One complaint involved a Silverado that would not stop normally at a stop sign. Brake failure is an immediate safety hazard and should be addressed before driving.
“I purchased the 2026 Chevrolet Silverado with a 6.2L motor "new" from the dealer with 5700 miles on XXX. Roughly a month and 2500 miles later, my family and I were in the vehicle, 750 miles from home, returning from a vacation to [XXX] from the [XXX]/[XXX] ar…”

Buyer analysis
KIA Optima or Chevrolet Silverado: which should you buy?
The Kia Optima has fewer complaints per year (about 609) compared to the Chevrolet Silverado (about 823), suggesting the Optima may have a lower overall rate of reported issues. However, both vehicles have serious engine and safety-related complaints, so the difference in volume does not necessarily mean one is problem-free. In practice, the Optima's issues seem more concentrated in engine oil consumption, while the Silverado's span engine, transmission, and brakes.
Key differences
- The Kia Optima has about 609 complaints per year versus about 823 for the Chevrolet Silverado, indicating a higher reported issue rate for the Silverado.
- Engine problems are the top complaint for both, but Optima owners often report oil consumption and power loss, while Silverado owners report engine shutdowns and stalling.
- The Silverado has more power train complaints (2,347) than the Optima has in any single category, with reports of transmissions suddenly going into neutral.
- Brake-related complaints are higher for the Silverado (1,222) than for the Optima (455), with Silverado owners describing severe loss of braking.
- Check the engine oil level and look for signs of excessive consumption or sludge, as many owners report sudden oil loss without leaks.
- Test the steering for any unusual noises or difficulty, and ask for records of any steering-related repairs.
- During a test drive, pay attention to any hesitation, stalling, or messages like 'Return to Neutral' that could indicate engine or transmission issues.
- Test the brakes thoroughly for firmness and stopping power, as some owners report sudden loss of braking effectiveness.
Before you buy
- Obtain a vehicle history report and confirm that all open recalls have been remedied by a dealer.
- Have a trusted mechanic perform a pre-purchase inspection, including a compression test and oil analysis for the Optima, and a transmission and brake check for the Silverado.
- Ask the seller for maintenance records, especially oil change receipts for the Optima and any engine or transmission repairs for the Silverado.
- Search the NHTSA database for complaints specific to the model year you are considering to see if common issues apply.
- During the test drive, listen for unusual engine noises, check for smooth shifting, and test the brakes at low speed in a safe area.
