1. What component or system failed or malfunctioned, and is it available for inspection upon request? The "coolant bypass hose/joint" (Part #: 16356-31051) located at the rear of the engine, connecting the two heads, failed. This part is made of plastic and is known to be a weak point in the 3.5L V6 (2GR-FKS) engine. The failed component is still in the vehicle and can be inspected upon request. 2. How was your safety or the safety of others put at risk? A coolant leak from this component can lead to engine overheating, which could cause sudden engine failure while driving, increasing the risk of an accident. Since the leak is not easily visible under the hood, a driver may not notice the issue until significant overheating occurs, potentially leaving them stranded in unsafe conditions. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the issue was confirmed by the dealership after an inspection. They identified the coolant bypass hose/joint as the source of the leak. Many users on the forum TacomaWorld have also experienced the same issue with their vehicles. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was inspected by the dealership, but it has not been inspected by Toyota directly, the police, or an insurance representative. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps or dashboard messages indicating a problem. The only symptom was a small puddle of coolant on the ground a week after purchasing the vehicle. Upon further inspection, a trail of coolant was observed running down onto the passenger side of the transmission bell housing. Would've costed me 1,000 dollars if didn't have warranty.

When stopping vehicle (for instance, at a stop light), vehicle would stop normally when pressing the brakes, but after a few seconds, the vehicle would start forward again. The brake pedal would give way and press down further, stopping briefly before starting forward again - so I had to use the emergency brake or else vehicle would move into oncoming traffic. I consulted a mechanic, and it was diagnosed as a bad brake master cylinder. This vehicle has only 51,000 miles on it, being a 2021 model. The brake pads themselves were checked and they are fine. I replaced the master cylinder and it fixed the issue, but I wouldn't expect this unsafe condition to already be happening to this vehicle, especially this early in life. Toyota must have defective brake master cylinders.

This vehicle stalled while driving. It would totally shut off. Once at 75 mph no warning just shut off. Had a cylinder misfire according to dealership. On 2 other occasions it shut off while driving. On those occasions I was backing up out of a driveway and driving slow on a drive. So very slow speeds. On those 2 occasions it had engine stall codes according to dealership. I filed a lemon law claim and because it didn’t stall in the 58 miles the tech drove it Tamara Clear from gulf states determined there’s no evidence it stalls despite the local Toyota dealership having stall codes in their notes. Tamara clear also didn’t comply with Arkansas lemon law and respond within 40 days. She took longer because she’s overwhelmed with cases according to her. Each time the vehicle totally shut off while driving it had master warning lights, charging system lights, oil fluid temp lights, all of it. I took pics but Toyota didn’t care about that either Potentially fatal. And they expected me to drive around with a 6 year old in it

Toyota addressed this issue with the frame paint peeling off long ago but they have not launched a customer support program to solve the problem yet. When we reached their Brand Engagement center line (1-888-270-9371) and they do not provide a hard or estimated date to launch the repair program. The vehicle was already inspected by Round Rock Tx Toyota service (PDF page) certifying the issue is a manufacturer responsibility. Please take care of this situation promptly.
