BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING
1 Report4% of totalPreviewing the first 1 complaint summaries.
The Rear Cross Traffic Warning signal is installed behind rear head rest, which muffles the alert sound to barely audible, even when setting is on high. Vanandergriff Toyota dealership in Arlington, Tx., verified this information to me after bringing my car in four times for service because I was not being warned of persons and vehicles passing behind me. I've called Toyota's home office and told nothing can be done, as it was installed this way, although I am still asking they remove muffling material or change location of warning equipment. It is very dangerous, as persons and cars are not always visible due to parking location or blind spots. This should be a recall item. All other warning signals on front of car work properly. I was told by company representative to just use drive-through parking! Consumer contacted Toyota customer service and the dealership in Arlington, Tx. where it was purchased. Consumer was told nothing can be done to fix the problem.

TIRES
1 Report4% of totalPreviewing the first 1 complaint summaries.
Bridgestone Turanza EL440BW 235 45R18 94V is original equipment on my 2021 Toyota Avalon Hybrid. Mileage at the time of the incident was 11398. I saw what appeared to be splitting or separation of the lower depth of the tread. No loss of pressure. I brought it to the Toyota Dealer to check. They insisted I must have hit something and would not consider it a manufactures warranty. I replaced the tire out of safety concerns. I do not recall hitting or going over anything. I am attaching photos of the condition. I replaced the one tire with the same make and model but remain concerned that splitting of the tread could be dangerous. And still have 4 like tires on the car.
