Should You Buy the 2020 Kia Sedona?
Reliability for this model year is excellent, and it stands well above average among 2020 SUVs. It is also among the stronger of the four scored Sedona years. Independent repair-cost data puts yearly repairs at $495 across the model, against $647 for its class. The 2019 rates worse and the 2021 rates better.
Power loss is the serious worry. One owner described the van dropping to a crawl at highway speed, with the accelerator pedal blamed and the problem returning after a warranty replacement. Electrical reports describe the van braking on its own or shutting down at speed, once ending up stopped in a travel lane at night. Heavy oil use appears around 100,000 miles, and some owners say warranty coverage was denied. The power sliding doors can jam, beep, or slam shut or open on an incline. There is one recall, in the electrical system.
Ask for proof that the electrical recall was completed. Request oil top-off and engine service history on any van near 100,000 miles, and test every sliding door. The 2021 is worth a look if you want fewer complaints and no recalls.
Compared to the 2021 Kia Sedona, which scored 5 points higher. See also the 2019 Kia Sedona for an earlier comparison.

Used Buying Checklist
Key things to inspect or verify before purchasing a 2020 Kia Sedona.
Cycle both power sliding doors fully open and closed, including on a slope, and listen for jamming, clicking, or beeping.
Inspect the roof behind the sunroof and the liftgate edges for peeling, flaking, or bubbling pearl white paint.
Check the dipstick and ask for oil top-off records or oil consumption test results, especially near 100,000 miles.
Scan for stored codes, including O2 sensor faults, and smell for exhaust or fuel odor with the engine running.
Start the van after it has sat in hot weather and note whether it fails to start on the first try.
Drive at highway speed and watch for sudden power loss, unexpected braking, or warning lights.
Test the battery and confirm every key fob starts the van and keeps it running.
Run the VIN through a recall check and confirm all open recalls have been completed.
2020 Kia Sedona Common Problems by Component
19 owner complaints grouped by vehicle system.
STRUCTURE
4 complaintsMost reports here involve the power sliding doors. A door may keep trying to open after it is already fully open, then jam, click, and beep. Other doors fail to open when needed, or cannot hold their own weight on an incline and slam open or shut with full force. Pearl white paint also peels, flakes, and bubbles, with spots reported on the roof behind the sunroof and along the liftgate edge. One filing in this category also describes steering shake, tread separation, and bent wheels.
ENGINE
3 complaintsThe most serious pattern is sudden power loss at highway speed. The van drops to a crawl, the check engine light comes on, and it will not accelerate normally. On an interstate, that creates a real crash risk. In the report describing it, the accelerator pedal was blamed, and the problem returned after a warranty replacement. Other complaints describe a check engine light with an exhaust or gas smell, traced to an O2 sensor and the exhaust gasket at the header. Hard starting in hot weather is also reported, returning every summer.
ELECTRICAL SYSTEM
3 complaintsPower loss while driving is the main pattern. The van brakes on its own or shuts down at speed as the forward collision warning, check engine, or other warning lights come on, and it can end up stopped in a travel lane at night. One case was diagnosed as battery failure, and the fault returned during the dealer's test drive. Other complaints describe headlights and taillights going dark, a driver's window stuck down, and a check engine light. Stalling in traffic carries a clear risk of being rear-ended.
UNKNOWN OR OTHER (3 complaints)
UNKNOWN OR OTHER
3 complaintsThe engine can shut down on the highway when the key fob loses communication with the engine computer. The immobilizer then blocks a restart even though the fob is inside the cabin, so the van is stranded on the shoulder. Other filings in this category cover a dead battery and a stuck AC control knob after a high pressure fuel pump replacement at 67,500 miles, with the owner billed for the follow-up repair. Owners also complain that they were never notified about an open recall.
POWER TRAIN (2 complaints)
POWER TRAIN
2 complaintsHeavy oil consumption shows up around 100,000 miles. The engine runs quarts low between top-offs and can stall and sound rough, sometimes along with an O2 sensor code. Severe cases move toward engine replacement. Both reports describe warranty disputes. Coverage is denied because the van is past the 100,000-mile manufacturer warranty, or because the V6 is not on the list of affected GDI engines. Running low on oil leads to stalling, which is a loss-of-power risk in traffic.
FUEL/PROPULSION SYSTEM (1 complaints)
FUEL/PROPULSION SYSTEM
1 complaintI received a letter from Kia America, Inc. extending the warranty on the high pressure fuel pump on my 2020 Kia Sedona. They claim that the fuel control valve plunger may wear unevenly and over time become stuck in the open position. They state different things can happen including stalling. My research found that it can cause stalling at high speeds or in heavy traffic and it may cause a loss of control over the vehicle. ARE THEY TRYING TO AVOID A RECALL. I am [XXX] and this sounds real dangerous. Does a serious accident have to happen before a recall is ordered? i have attached a copy of the letter below.

1 complaintThe contact owns a 2020 Kia Sedona. The contact was notified by the local Police that the rear brake lights were not illuminating as needed. The vehicle was later taken to the local mechanic who was unable to determine the cause of the failure. Later while driving approximately 20 MPH and depressing the brake pedal, the brake pedal extended to the floorboard. The vehicle was immediately towed to the local dealer. The cause of the failure was not yet determined. The manufacturer was notified of the failure. The failure mileage was 41,000.
