2020 Toyota Prius Common Problems by Component
30 owner complaints grouped by vehicle system.
VISIBILITY/WIPER
5 complaintsSafety-relatedOwners of the 2020 Toyota Prius report issues with windshield and mirror visibility. Several complaints describe the development of frost on the inside of the windshield, requiring 20 minutes or more to defrost, which occurs in various locations and under different weather conditions. Another owner notes a spiderweb crack appearing on the windshield, potentially related to temperature changes. A distinct issue involves the right side mirror glass detaching while driving, posing a safety risk to other motorists. One complaint involves a crash due to a dashboard cover obstructing a sensor, leading to a darkened display screen, although no injuries were reported. These issues typically occur in vehicles with mileage ranging from 8,000 to 12,000 miles.
ELECTRICAL SYSTEM
4 complaintsSafety-relatedOwners of the 2020 Toyota Prius report issues primarily related to unintended acceleration and display malfunctions. Two complaints describe incidents where the vehicle unexpectedly accelerated, with one resulting in a crash and an injury. These incidents occurred at low speeds, and one owner notes the problem followed routine maintenance. Additionally, owners report problems with the vehicle's display systems, including the multi-information display failing and the media-control unit intermittently going blank, affecting the use of climate controls.

VEHICLE SPEED CONTROL
3 complaintsSafety-relatedOwners of the 2020 Toyota Prius report incidents involving unexpected acceleration, particularly at low speeds around 5 mph, often while making turns or parking. Complaints frequently mention that the vehicle accelerates suddenly without warning, leading to crashes such as jumping curbs, sideswiping other vehicles, or hitting walls. In these cases, the brake pedal is reportedly unresponsive, and no warning lights are illuminated. The mileage at which these incidents occur varies, with reports at approximately 15,670 and 54,300 miles. These incidents sometimes result in crashes, highlighting a potential safety concern for prospective buyers.
AIR BAGS (2 complaints)
AIR BAGS
2 complaintsSafety-relatedOwners of the 2020 Toyota Prius report issues with airbag deployment during crashes. In one incident, the airbags failed to deploy when the vehicle was struck at high speed after another driver ran a red light, resulting in two injuries. Another owner describes unintended acceleration while parking, leading to a collision with a building; again, the airbags did not deploy despite significant front-end damage. Both complaints involve crashes, with one occurring at approximately 14,000 miles. These reports suggest potential safety implications related to airbag performance in crash situations.

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.

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

How We Calculate Reliability Scores
Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.
Key Ranking Factors
Complaint Severity
NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.
Repair Costs
Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.
Recall Impact
Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.
Issue Diversity
Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.
Scores are grouped into four tiers:
- 80–100: Excellent— Top-tier reliability, minimal issues
- 60–79: Good— Reliable with some minor concerns
- 40–59: Mixed— Notable issues, research before buying
- 0–39: Risky— Significant problems, proceed with caution
Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
