Should You Buy the 2020 Toyota Prius?
Good reliability, and a solid pick among used sedans. Owner complaints and recall records put this year well above the average 2020 sedan, and among the stronger of the nine scored Prius years. Independent repair-cost data estimates about $408 a year to keep it running, against $526 for its class. It also earned five stars in federal crash testing.
The complaints that matter are about control. Owners describe the car surging at low speed while leaving a parking lot or entering a garage, in some cases ending in a fence, pole, or curb. One driver reported the transmission dropping into neutral on the freeway. Dashboard and media screens can go dark while driving, which hides the defrost and climate controls. Tire sidewalls have also bulged or blown out, once at 3400 miles. One federal recall covers electronic stability control and service brakes.
Ask the seller for proof that the recall work was done, plus any tire replacement records. The 2019 rates about the same but has more complaints and recalls. The 2021 rates better and has no recalls.
Compared to the 2021 Toyota Prius, which scored 3 points higher. See also the 2019 Toyota Prius for an earlier comparison.

2020 Toyota Prius Recall Details
1 recall has been issued for the 2020 Toyota Prius. All recall repairs are performed free of charge at authorized dealerships.
ELECTRONIC STABILITY CONTROL (ESC), SERVICE BRAKES
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2019 Lexus LS500, LC500, ES300h, UX250h, LS500h, Toyota Prius, RAV4 HV, 2019-2020 Toyota Prius Prime, and 2020 Corolla HV vehicles.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 126, "Electronic Stability Control Systems."
Consequence
Deactivation of the vehicle stability control system or a loss of braking assist increases the risk of a crash.
Remedy
Toyota will notify owners, and dealers will inspect and, if necessary, replace the brake booster pump, free of charge. The recall began September 20, 2019. Toyota owners may contact Toyota customer service at 1-888-270-9371 and Lexus owners may contact Lexus customer service at 1-800-255-3987. Toyota's numbers for this recall are K1L/K0L.

Used Buying Checklist
Key things to inspect or verify before purchasing a 2020 Toyota Prius.
Ease into several parking spaces at walking speed and confirm the car never surges and the brakes hold.
Make firm stops from moderate speed and feel for pedal vibration or a sliding sensation.
Inspect every tire sidewall for bulges or ballooning, and note the tire brand.
Have a shop read stored engine, throttle, transmission, and hybrid system warning codes.
Watch the gauge display and touchscreen for blanking, and test heat, air conditioning, and defrost controls.
On the highway, confirm the transmission stays in drive and never drops to neutral by itself.
Look under the hood for chewed wiring or a damaged air filter.
Check the windshield near the camera for cracks and both outside mirror glasses for looseness.
2020 Toyota Prius Common Problems by Component
30 owner complaints grouped by vehicle system.
VISIBILITY/WIPER
5 complaintsSafety-relatedFrost forms on the inside of the windshield while the car is parked, and clearing it takes 20 minutes or more. One report adds that the wipers turn water and snow into ice. Other complaints describe a long crack spreading from under the camera area after defroster use at about 8000 miles, and outside mirror glass falling off while driving. In that case the dealer replaced the whole mirror. The one crash-related report involves an aftermarket dashboard cover that blocked a sensor and darkened the screen while reversing, ending in a low-speed bump.
ELECTRICAL SYSTEM
4 complaintsSafety-relatedSudden full-throttle acceleration at low speed is the most serious pattern here. Two reports describe the car surging while leaving a parking lot or entering a garage, then hitting a fence or a pole. One crash injured the driver and triggered a check-engine warning about engine, throttle, or transmission control. Separately, screens go dark. The instrument display stops showing speed, fuel, and odometer, and the media touchscreen blanks partly or fully while driving. That cuts off access to heat, air conditioning, and defrost controls.
TIRES
4 complaintsSidewalls blow out or balloon with little warning. This happens at highway speed on smooth pavement and at low speed right after a full stop. Failures come early: one at 3400 miles, another at 24k, where the dealer found bulging on all four tires. One report names the original-equipment Toyo NanoEnergy A41 in 195/65R15 size. Another involves replacement Goodyear Assurance MaxLife tires. None of these complaints reports a crash, but a blowout at highway speed carries a real risk of losing control.
POWER TRAIN (4 complaints)
POWER TRAIN
4 complaintsSafety-relatedThe car accelerates on its own while creeping into a parking spot. In one case it jumped a curb and hit two vehicles. Another report describes the transmission dropping from drive into neutral on the freeway with no driver input, leaving the car without power until it was shifted back. Rodents chewing through wiring and the air filter set off a check hybrid system warning and rough running, and the dealer bill came to $13066.81. One complaint covers transmission and suspension repairs after a tow.
SERVICE BRAKES (3 complaints)
SERVICE BRAKES
3 complaintsSafety-relatedThe brake pedal fails to stop the car. Two of the three complaints end in crashes, with two people injured. In one, the brakes did not respond on the highway in a car with 700 miles, and the car was totaled. In another, the car sped up instead of stopping while parking in a garage. A third report, at about 67,000 miles, describes a vibrating pedal and an on-ice feel at 40 mph with no warning light. Both crash reports describe brake failure and sudden acceleration happening together.
UNKNOWN OR OTHER (3 complaints)
UNKNOWN OR OTHER
3 complaintsSafety-relatedSudden surging while pulling slowly into a parking space dominates this category. Drivers say the car shot forward even after they moved to the brake. One of these surges ended in a crash into a concrete pole that injured the driver. Another owner reports two surges about a year apart. The first time, collision-avoidance braking stopped the car short of a fence. The third complaint mentions the original dealership tires but does not describe a failure.
VEHICLE SPEED CONTROL (3 complaints)
VEHICLE SPEED CONTROL
3 complaintsSafety-relatedSudden acceleration at parking-lot speeds, around 5 mph, is the only pattern, and all three complaints end in crashes. Drivers describe the car surging while turning or pulling into a space, with the brakes failing to slow it, wheels squealing, and no warning lights. Cars jumped curbs, went into bushes, sideswiped a parked car, and hit a wall. In every report that mentions a dealer, the car was not diagnosed or repaired. Reported mileages are 15,670 and about 54,300.
AIR BAGS (2 complaints)
AIR BAGS
2 complaintsSafety-relatedNo air bag deploys in either reported crash. In one, the car surges forward while parking at 14,000 miles and hits a building, severely damaging the front end. In the other, a driver who ran a red light strikes the car. The owner reports that the anti-collision sensors and the air bag both failed to respond, and two people were injured.
BACK OVER PREVENTION (1 complaints)

ELECTRONIC STABILITY CONTROL (ESC)
1 complaintPROXIMITY SENSORS GENERATED AN ALERT THAT PARKING ASSISTANCE SENSORS NEEDED CLEANING DURING MODERATE RAIN CLEANING THE SENSORS DID NOT RESOLVE THE ISSUE. STOPPED AT DEALER TO HAVE IT CHECKED AND WAS ADVISED THAT THE SENSOR DO THAT IN INCLEMENT WEATHER AND I WOULD NEED TO LEARN TO LIVE WITH IT. IF IT WAS JUST THE PARKING SENSORS IT WOULD NOT BE AS SIGNIFICANT BUT I DID DETERMINE THE FRONT ACCIDENT ASSISTANCE DID NOT FUNCTION AS IT SHOULD HAVE - AS I APPROACHED A VEHICLE IN FRONT OF ME WITH CRUISE CONTROL THE SPEED REDUCTION THAT WAS SUPPOSED TO OCCUR DID NOT HAPPEN. HAD I NOT BEEN CHECKING TO SEE WHAT WOULD HAPPEN IF THE PROXIMITY SENSORS WERE MALFUNCTIONING IT COULD HAVE RESULTED IN AN ACCIDENT. I DID NOT ATTEMPT ANY OTHER ACTIONS WHICH RELY ON PROXIMITY SENSORS TO FUNCTION AS I DID NOT WANT TO CAUSE OR BE INVOLVED IN AN ACCIDENT. I WAS DRIVING AT THE TIME AND I EXPECT THAT ALTHOUGH THE ALERT SPECIFICALLY MENTIONED PARKING SENSORS, THE FACT THAT THE CAR DID NOT SLOW AS TOYOTA HAS INDICATED IT SHOULD LEADS BE TO BELIEVE THAT ANY AND ALL "DRIVER ASSISTANCE TECHNOLOGIES" MAY FAIL WHEN THAT ALERT OCCURS RESULTING IN POTENTIAL ACCIDENTS AND INJURIES THE VSC OFF INDICATOR WAS FLASHING AT THE TIME. *TR
