New Car Assessment Program
The 2020TOYOTACOROLLA carries 376 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 35 crashes, 2 fires, 43 injuries, and 1 fatality. For crash performance, NHTSA's New Car Assessment Program gave this cohort an overall 5/5 rating, with 5/5 front crash, 5/5 side crash, and 4/5 rollover scores derived from standardized barrier and dynamic tests.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2020 COROLLA is engine with 104 filings, followed by unknown or other (75) and power train (32). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 3 active recall campaigns, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 3 investigation files overlapping the 2020 COROLLA. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

The windshield wiper switch assembly (column stalk/switch) malfunctions intermittently, sending unintended signals that activate the wipers despite the stalk being firmly in the OFF position. The component is still installed in the vehicle and is available for inspection upon request. Suspected part numbers include 84652-06400 or similar variants. How was your safety or the safety of others put at risk? Sudden, unexpected wiper activation (typically 1-2 wipes, occasionally more) while driving creates a serious distraction and safety hazard. It can startle the driver, cause momentary loss of vehicle control or focus (especially at highway speeds or in traffic), and briefly obstruct vision. This risk is heightened during rain, when wipers are needed but behave erratically, or during acceleration/turns where vibration triggers itâpotentially leading to accidents. Has the problem been reproduced or confirmed by a dealer or independent service center? No, the Toyota dealership has not re
On the morning of January 7, 2026, while I was on my way to work, I experienced a dangerous incident involving my vehicle. As I arrived at the first stop on the street, I suddenly heard a loud explosion. Immediately afterward, pieces of glass began falling onto my windshield. I pulled over and exited the vehicle to assess the situation. Upon inspection, I discovered that the sunroof of my car had completely shattered. Glass was scattered across the roof, windshield, and interior of the vehicle. Prior to the explosion, there were no visible signs of damage to the sunroof. The incident occurred without warning and posed a serious safety risk. I am submitting this complaint to formally document what happened and to request that the matter be investigated and addressed appropriately.
Clutch slave cylinder started leaking leading to a sticking clutch pedal, making it difficult to engage the transmission with the engine, and a lower brake/clutch fluid level which could have caused braking issues if the fluid got too low.

Engine coolant bypass valve
Clutch Slave Cylinder at 51,000 miles failed causing vehicle clutch to not return and loss of fluid. Brake fluid and clutch fluid are used in the same reservoir and could cause issues causing vehicle to not be able to stop. Vehicle has been inspected by shop and has been replicated. The part exploded and leaks fluid inside of transmission housing. This also causes the clutch to fail as-well. Vehicle has always been serviced and maintained and this is a common issue with all vehicles that have 6 speed manual transmission with varying mileage. It is not a matter of if, itâs when and due to this being something that happens with generally no warning signs can be dangerous. There needs to be an updated part that can handle the design Toyota chose for this transmission.
FAULTY HYDRAULICS IN THE TRANSMISSION SYSTEM. FAULTY SLAVE CYLINDER LEAKING FLUID AND POTENTIALLY CAUSING VEHICLE TO BECOME "STUCK" IN GEAR WHILE DRIVING OR UNABLE TO SHIFT INTO GEAR WHILE PARKED. NOT AN UNCOMMON ISSUE WITH THESE MODELS.
Beginning on April 18, 2025, my 2020 Toyota Corolla LE began experiencing repeated failures involving multiple safety systems while driving. Without warning, several lights illuminate at the same time, including: Brake System Malfunction, Pre-Collision System, Parking Brake System, Vehicle Stability Control, Check Engine, and Secondary Collision Brake System. These warnings appear suddenly during normal driving, then sometimes disappear, then return again unpredictably. These failures disable several integrated safety systems and create a serious safety risk due to changes in braking performance, loss of stability control, and disabled collision-avoidance functions. Diagnostic scans from both the dealership and an independent mechanic repeatedly show: P1578 â Brake System Malfunction P265B â Rocker Arm Actuator Position Sensor Circuit Range/Performance (Bank 1) Both codes reappear even after being cleared. The vehicle was with Loving Toyota Lufkin, TX multiple times over seve

This is in regards to toyota CSP 24TE04 and the Engine Bypass System. This was also included in a class action lawsuit that got dropped. Engine Bypass System is faulty and shows check engine requiring replacing of Bypass Valve and or wiring. According to 24TE04 it has been affecting over 2 million cars, but not all are being fairly covered. They need to include all models with this system that were produced during this time. Thank you

I was driving normally to work and the vehicle stalled without warning and became difficult to steer. The dashboard displayed âengine stopped, steering power lowâ. The vehicle was stalled in the middle of the roadway and could not be restarted for 10 minutes. This was a very dangerous way to stop and then not be able to restart. People had to get out of their vehicles and help me push it out of the roadway. After 10 minutes the vehicle started and drove normally without any issues. The battery and alternator tested good. The mechanic can not find anything wrong. I am scared to drive the vehicle now and have an accident due to this incident.

The contact owns a 2020 Toyota Corolla. The contact stated that after the vehicle was started, the contact started driving, and a voice message was heard coming from the speaker on the driverâs side door, stating that the communication module had failed. The vehicle was taken to the dealer, where it was diagnosed, and determined that the Data Communication Module needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was informed of the failure. The failure mileage was approximately 38,000.
Mileage: 38,000
At 97,000 miles, the slave cylinder in my vehicle blew. My clutch pedal had stuck to the floor, and my brakes became harder and harder to press down because the clutch takes from the brake fluid reservoir. Brake fluid began to leak from the transmission, and it had to be towed in. If I hadn't come to a stop, I could have gotten in a horrible accident.
I was driving on the freeway on my way to the house my car start to make some noises and I was loosing power I pulled up on the shoulder and turn off the car because the check engine came on turn off the car again but was struggling to go into first gear
