What actually goes wrong
The problems owners report
The most-complained-about systems on each vehicle — what fails, and what owners say in their own words.

- 03ELECTRICAL SYSTEM723
- 04STEERING720
- 05SERVICE BRAKES455
Owners report sudden oil loss with no visible leak, followed by engine knocking or failure, even when oil changes are kept up. This matters because a used Optima can strand you without warning if oil consumption is not checked regularly.
Complaints include excessive oil consumption tied to electrical warnings and ongoing oil-level issues that require frequent top-offs. Buyers should expect to monitor oil level and warning lights closely.
With 720 steering complaints, owners describe steering difficulty or unusual feedback that can affect control. A pre-purchase inspection should specifically test steering feel and listen for noises.
There are 455 brake complaints, often about premature wear or reduced braking performance. This is a safety-critical area, so a mechanic should check pad and rotor condition before buying.
“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…”

- 05ENGINE880
Owners report the truck entering limp mode, getting stuck in 5th gear, and lead frame failures that can cause sudden loss of power. These issues can happen daily and may lead to near-collisions, so a transmission scan and test drive are essential.
Complaints include lead frame problems and output speed sensor failures that trigger limp mode and error codes like P0722. Electrical gremlins can leave you stranded, so check for stored codes and recall completion.
With 1,224 lighting complaints, owners report issues that can affect visibility and safety. Inspect all lights, including brake and reverse lamps, for proper function.
There are 880 engine complaints, often related to drivability and power loss. A used F-150 should have a compression test and a scan for engine-related fault codes.
“This lead frame issue is never ending. Well over a decade without a proper remedy. I’m very familiar with it. but this one nearly ended my life. After the near collision I called my mechanic and bought a new ford lead frame from a dealership. It’s doing fine…”

Buyer analysis
KIA Optima or FORD F 150: which should you buy?
The Kia Optima has far fewer complaints per year (about 609) than the Ford F-150 (about 1,162), so on paper the Optima sees less frequent owner-reported trouble. In practice, the Optima's issues cluster around engine oil loss, while the F-150's center on transmission limp mode and lead frame failures that can be more immediately dangerous.
Key differences
- The Ford F-150 averages about 1,162 complaints per year versus about 609 for the Kia Optima, so the Optima sees roughly half the annual complaint rate.
- Optima owners most often report engine oil loss and power loss, while F-150 owners report transmission limp mode, stuck gears, and lead frame failures.
- The F-150 has 151 recalls and 297 injuries reported, compared with 41 recalls and 191 injuries for the Optima.
- Both vehicles have electrical complaints, but the F-150's electrical issues are tied to drivetrain limp mode, whereas the Optima's often relate to oil consumption warnings.
- Check the oil level and look for any sign of excessive consumption or sludge; owners report sudden oil loss with no visible leak.
- Scan for stored engine and transmission codes, and test drive for hard shifting or power loss, especially after any emissions software update.
- Test drive at highway speed and watch for limp mode, stuck gears, or delayed engagement; lead frame and output speed sensor failures are common.
- Inspect the rear window defroster and all exterior lights, as owners report shorts that can shatter the back window and lighting failures.
Before you buy
- Ask for proof that all open recalls have been performed on the specific vehicle you are considering.
- Have a mechanic check oil level and look for signs of excessive consumption or leaks on the Kia Optima.
- On the Ford F-150, request a transmission scan and a test drive that includes highway speeds to check for limp mode.
- Verify the rear window defroster and all exterior lights work on the F-150, and check for any signs of electrical shorts.
- Obtain a vehicle history report and compare the complaint patterns to the model year you are buying.
