2020 TOYOTA COROLLA Complaints

Electrical issue on vehicle says that vehicles safety features are unavailable and all the light indications on the dash are lit up. It was taken to the dealership several times but the issue still hasn’t been resolved.

The contact owns a 2020 Toyota Corolla. The contact stated while the vehicle was parked, the gear shifter was shifted to drive and then reverse, but the vehicle failed to respond as needed. No warning light was illuminated. The vehicle was towed to the dealer and a diagnostic test was performed. The vehicle was diagnosed with a locked cylinder. The dealer stated that there was recall for the failure however, the vehicle had exceeded the mileage limitation. The vehicle was repaired. The contact referenced NHTSA Campaign Number: 19V544000 (Electronic Stability Control, Service Brakes) as a possible solution to the failure however, the VIN was not included in the recall. The manufacturer was not made aware of the failure. The approximate failure mileage was 90,249.

There is a thing that’s happening to a lot of Corollas and I think RAV4 and some cram it’s called engine maintenance required and a lot of mechanics don’t know what that means so you have to take it to the dealership to get it fixed and it’s like a $900 fix and it’s been happening to a lot of vehicles around 35,000 miles. It’s called the coolant bypass valve. There is hundreds of YouTube videos about it and people complaining about it on forums.

The coolant bypass valve in some Toyota models has been malfunctioning recently and has become a common issue. Dealer confirmed that this was the issue per attached diagnostic report/invoice copy. Costs were >$800 to repair the issue for a <$100 part and 30 minutes of labor. The "Engine Maintenance Required" warning was visible in the display. Unsure as to the short or long-term effects of this malfunctioning part, but as it's related to the cooling system of the vehicle, it may trigger other more serious issues.

Around 40k miles I received an Engine Maintenance Required warning. After some research Engine Maintenance and Engine Service Required are two very different indicators. I received and P2681 code meaning the electrical coolant bypass valve had failed unfortunately one can’t tell if it’s stuck shut or open this could lead to one’s care over heating and or damaging one’s engine. After some research I’ve come to find out most 2020-2024 corollas have been having this issue tends to happen about 30-50k miles

Precollision System Malfunctioning and Hybrid System Malfunctioning warning signs on dashboard won’t allow the car to move or driven at all. I read reviews where people with the same warning signs on dashboard got their car stalled in the middle of the road. My vehicle only has 81,000 miles on it and Toyota dealership warranty states it’ll cover the vehicle up to 150,000 miles EV hybrid but now they are stating the car is not under warranty

My car, a 2020 Toyota Corolla Hybrid, impacted an abandoned motorcycle on the dark road at full speed; however, none of the airbags deployed.

In the past week at 30,700 miles, my 2020 Toyota Corolla "Engine Maintenance light; see dealer" service light appeared on the dash. Through talking with a Toyota dealer, they are aware of this issue with Corollas, Camrys, and Rav4's. It is an engine coolant bypass valve, and appears to be faulty in many vehicles according to youtube videos, google, and Toyota service. Perhaps this needs to be a recall? Also, the dealer wants almost $800 to repair even though many people do it on youtube in under an hour. Parts are less than $200, and 1.5 hours of labor do not add up to $800.

Driving approximately 20 mph- hear a beep- get instructions to go to neutral- check engine light / power steering lights are on- pulled off the side of the road- put in park, turned off and waited a minute and it started normally.
