AIR BAGS

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2011-2019 Corolla, 2011-2013 Matrix, 2012-2018 Avalon, and 2013-2018 Avalon Hybrid vehicles. During certain crashes, the air bag electronic control unit (ECU) may malfunction, possibly disabling the deployment of the air bags and/or seat belt pretensioners.

Consequence

In the event of a crash, air bags and/or seat belt pretensioners that do not deploy as intended may increase the risk of injury.

Remedy

Toyota will notify owners, and dealers will inspect the ECU and install a noise filter between the air bag control module and its wire harness, as necessary, free of charge. Owners were notified of the safety risk beginning March 2, 2020. A second letter notifying owners of the remedy repair will be mailed between March 16, 2020 and June 27, 2020.

Hello, My name is [XXX]. I bought my car from Longo Toyota in El Monte about 15 months ago. The car was certified preowned and had a Carfax report with no accident reported history. That is exactly why I bought the car, because this was going to be my family car. So I bought it and have been driving around my daughter, who just turned one for over a year. I also work as a Behavioral Therapist and drive around kids with autism in my car on a daily basis. It wasn’t until I decided to trade in my car that it was discovered that the Avalon car has frame damage, which was discovered by third-party. A car condition expert came to check out the car and discovered the frame damage by using a true frame meter and a paint meter. Now Longo Toyota in El Monte has gave me the go around and hasn't even checked for frame damage. Longo Toyota is asking me how much would I want for my car and asking me about my car's value. There is clear fraud going on, and the fact that this is the largest car dealership in the country makes me wonder how many more people are driving around in cars that have frame damage as well. Best regards, [XXX] “INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

FORWARD COLLISION AVOIDANCE

THE PRE-COLLISION BRAKING SYSTEM DOES NOT APPEAR TO WORK. SEVERAL TIMES WHEN CARS IN FRONT OF US HAVE SLAMMED ON THEIR BRAKES, THE PRE-COLLISION BRAKING SYSTEM DOES NOT RESPOND. WE OWN A 2016 PRIUS WITH THE SAME FEATURE AND IT ALWAYS RESPONDS ' FLASHING A WARNING AND APPLYING THE BRAKES. WE COMPLAINED TO THE DEALERSHIP MULTIPLE TIMES, AND THEY SAID THE SYSTEM IN OUR CAR PERFORMS A CHECK EVERY TIME WE TURN ON THE CAR AND SINCE IT DOES NOT INDICATE A FAULT, TO THEIR KNOWLEDGE THE SYSTEM IS WORKING FINE. THEY SAID THERE ARE NO OTHER TESTS FOR THEM TO PERFORM. I'VE ADJUSTED THE SYSTEM TO THE MOST SENSITIVE MODE (ACTIVE WHEN VEHICLE IN FRONT OF US IS FURTHER AWAY), BUT THIS HAS HAD NO EFFECT. ALSO, THE ADAPTIVE CRUISE CONTROL WHICH USES THE SAME RADAR SYSTEM AS THE PRE-COLLISION BRAKING WORKS FINE. THERE DEFINITELY IS SOMETHING WRONG WITH THE PRE-COLLISION BRAKING, AND I AM CONCERNED THAT THIS SAFETY FEATURE WILL NOT SAVE US FROM A COLLISION. THE ONLY WAY SOMEONE WOULD BE AWARE THAT THE SYSTEM ISN'T WORKING IS TO EXPERIENCE A NEAR COLLISION. I BELIEVE THE PRE-COLLISION BRAKING SYSTEM COULD BE TESTED WITHOUT DAMAGING OUR CAR BY PLACING A LARGE STATIONARY INFLATABLE OBJECT IN FRONT OF OUR MOVING CAR. I WOULD BE GLAD TO PROVIDE OUR CAR FOR YOU TO PERFORM SUCH A TEST OR ANOTHER TEST THAT YOU MAY HAVE DEVELOPED. THIS MAY BE A PROBLEM WITH MANY OTHER TOYOTA AVALONS AND OTHER CARS.

MY AUTO HIGH BEAMS DAILY FAIL TO WORK CORRECTLY DURING NIGHT TIME DRIVING, THE LOW BEAM WOULD BE ON, THE TURN SIGNAL CONTROL LEVER WILL BE PUSHED ALL THE WAY FORWARD. THE GREEN LIGHT ON THE DASH PANEL IS SHOWING A HEADLIGHT WITH A WORD "AUTO" WOULD ILLUMINATE AND THE HIGH BEAMS WOULD CYCLE ON & OFF AS THEY SHOULD WITH THE AUTO HIGH BEAM SYSTEM. THEN THE GREEN "AUTO" LIGHT WOULD MYSTERIOUSLY GO OFF AND THE HIGH BEAMS WOULD NOT TURN ON ANYMORE EVEN UNDER THE RIGHT CONDITIONS - THIS WOULD LAST FROM THIRTY SECONDS TO ABOUT FIVE MINUTES..THEN THE AUTO HIGH BEAM SYSTEM MYSTERIOUSLY COMES BACK ON AND ALL WORKING CORRECTLY AGAIN. THIS IS ONLY ON NIGHT TIME DRIVING WHEN THE AUTO HIGH BEAM SYSTEM IS TURNED ON WITH THE GREEN AUTO INDICATOR. THIS IS WHEN THE VEHICLE IS IN MOTION AND MOSTLY ON DARKER / RURAL ROADS WHERE HIGH BEAMS ARE DESIRED. THIS PROBLEM IS WITH THOUSANDS OF TOYOTAS..AND LEXUS ES ALL MODELS AND THE LAST FIVE MODEL YEARS. DEALERS TURN A BLIND EYE TO IT... ALTHOUGH IT IS OFTEN A VERY INTERMITTENT PROBLEM. TOYOTA DEALERS WILL NOT ACKNOWLEDGE IT... LOOK IN ALL THE TOYOTA ONLINE AUTOMOTIVE FORUMS... IT'S OUT THERE...THIS HAPPENS EVERY AND ANY EVENING WE DRIVE THE CAR AT NIGHT. VERY ANNOYING FOR SURE.

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

1

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.

2

Repair Costs

Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.

3

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.

4

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.

Get notified when new recalls or reliability data is added for the Toyota Avalon.

No spam. Only data updates for this model.
