| Engine And Engine Cooling problems |
The component that failed is the coolant bypass valve, which is part of the engine cooling system. The vehicle is available for inspection upon request. The issue was first indicated by an "engine maintenance required" warning message that appeared on the dashboard. No prior symptoms were noticeable before the warning appeared. The warning came on suddenly during normal driving conditions. This failure poses a potential safety risk because the coolant bypass valve regulates engine temperature. If it malfunctions, it may lead to improper engine cooling, overheating, reduced engine performance, or sudden breakdown while driving. This could increase the risk of being stranded in traffic or experiencing a hazardous situation on the road. The problem has been diagnosed and confirmed by an authorized Toyota dealership, which identified the coolant bypass valve as failed and in need of replacement. The dealership provided a repair estimate of $775 prior to taxes and fees. The manager shared that it would be around $890+ after it is all calculated. The vehicle has not been involved in any accident related to this issue, but the malfunction was verified through dealer inspection. No police or insurance reports were filed, as this was a mechanical failure. Based on personal research, this appears to be a widespread issue affecting similar Toyota vehicles, including other Corollas and rav4 models, where the same component has failed under similar conditions. In some cases, repairs have been covered by the manufacturer, indicating awareness of the issue. There are many groups on facebook and reddit where customers with the same make and model 2022 Toyota Corolla se have had the same issue after 3 years of having the vehicle. In summary, while driving under normal conditions, the warning message appeared without prior indication. The dealership later confirmed that the coolant bypass valve had failed and required replacement.
Dear national highway traffic safety administration, I am submitting this email to formally report a potential vehicle safety defect involving my 2022 Toyota Corolla. Vehicle information: - make/model: 2022 Toyota Corolla - in-service date: 08/18/2022 my vehicle sustained significant wiring damage caused by rodents. Toyota has denied warranty and financial assistance, characterizing the issue as an “outside influence. ” however, according to what I read online, modern vehicles —including Toyota models—use soy-based or bio-based wiring insulation, which is widely documented to attract rodents. The damage affected critical electrical wiring, creating potential safety hazards including loss of vehicle function and increased fire risk. This is not merely cosmetic damage but impacts essential vehicle systems. The foreseeability of rodent attraction due to wiring materials raises concerns of a design-related safety defect and failure to adequately warn consumers. Toyota has stated there are no recalls or customer support programs addressing this issue, despite recurring reports from vehicle owners nationwide. I respectfully request that NHTSA review this matter as a potential safety defect and consider whether further investigation is warranted. Thank you for your attention to this safety concern. Sincerely,.

I bought my car Toyota Corolla coss has three months with 3,700 miles on it. And has had two times problems. The first time, on February 28 2023 at 8 a. M. , I was at a traffic light stop my car about 15 seconds later when I heard a warning beep. The message read "low steering power," low battery, and then steering lock. I tried to turn off the engine button, but there was no response. I pressed it three times, put the handle stop on the park, and then started it again. My car was parked in the middle of the road, causing a traffic jam behind me, and I couldn't get out because it was dangerous. The second time in March 10. 2023 3pm. After the stop at the light and anything like first time. . . It was rainy both times. I'm worried it's dangerous on the highway. It was raining and I had my wipers on and my stop and start system on. I haven't reported it to Toyota dealership. Both of them are in the middle of the road. I'm not sure if there are any defects in this car. Thank you!.
There has been several instances where I’m trying to cross a divided highway and the accelerator doesn’t respond. I’ve had three near death experiences. There’s been other times where it will just shut off and restart without a warning. It’s been in my driveway thankfully. When I pull out in front of someone, it doesn’t respond either. I have had the pedal all the way down to the floor and it wouldn’t go for about 5-6 seconds.
The car had shut down on the street while driving twice.
This vehicle stalls intermittently when it comes to a full stop. This problem still exists and last occurred on June 27, 2022. The vehicle has an intermittent issue (unpredictable with months, or minutes in between). Weather and road conditions have varied. Location has varied as well. Dates of occurrence are February 13, 2022; March 12, 2022 (occurred twice within a 20-minute time span); and June 27. The vehicle stalls when it comes to a full stop (on all four occasions, this has occurred at a red light). The check engine light and the power steering light come on, as well as a message on the dashboard, stating, "engine stopped. Steering power low," "engine stopped. Press break firmly to restart," and "press break firmly to restart engine. ----- to start. " during this time, a continuous *beep* is coming from the car. Shifting to neutral, manual, drive, or reverse does not resolve the issue. Shifting to park makes the beeping sound go away, and I have to power on the car. On all four occasions, this happens seconds before or while the light turned green on high-speed and residential multi-lane routes. I have video evidence of this issue, but that is not an allowed file format.
