When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS

I am reporting a severe vehicle safety violation involving a Westlake tire on a 2018 Toyota Yaris rented through Turo (Claim 1060794). The vehicle host rented out the vehicle with a pre-existing, structurally ruptured tire sidewall bulge on the front passenger wheel. The host took a pre-trip photo documenting the failing tire with a gauge but failed to ground the vehicle, choosing instead to temporarily inflate it with air to mask the low-pressure warning light. The tire structurally failed during operation, forcing a replacement. A formal safety investigation is requested into this safety failure for deploying a non-roadworthy, structurally compromised vehicle onto public roads. TIRE SIZE 185/60R16

TIRES:SIDEWALL

This is a safety issue that needs to be addressed. I informed the Manufacturer , Yokohama, as soon as the incident occurred and had to be replaced by a tire shop. These tires can explode if they hit anything, on the side, at less than 2mph (two miles per hour).

SERVICE BRAKES

I’m reporting a vehicle safety problem. My 2018 Toyota Yaris IA just had a mileage of 823 miles and was within the warranty time and had a brake system problem caused by the Toyota car quality problem. On August 22 (Sunday), 2021 about 1:00 pm I, with my wife, was going to drive my 2018 Toyota Yaris IA to my daughter’s house to see our five grandchildren as we did since April when we had covid 19 vaccine. When I started the car in my house parking lot, I was surprised to find several indicators of the brake system malfunction were on the car’s computer screen. Not only did the indicators still exist in the screen, I felt the car was shaking when I was driving about 30 feet. I immediately returned back to my house parking lot and found a new problem that the air conditioning didn’t work either. I decided not to drive this car. The next day, August 23 about 7:00 am, I drove to Oakton Sonoco Auto Service Center. There, Jim, the manager, found the same indicators of the brake system malfunction, he at once told me, “Your car just has 800 mileages and is under warranty. You should drive to the Toyota dealer immediately.” Then I drove to Ourisman Fairfax Toyota at about 7:25 am and told Mr. Carroll Hyman about the car problems. At about 4:00 pm he called me and said, “Mice bit and broke the wires to damage the wire system. Your car’s repairing can not have the warranty.” I asked, “Did you see the mice?” He answered, “Yes, the mice were in the wires close to the engine”. He didn’t mention whether the mice were alive or dead. If the mice were alive when he saw them, how could the mice be still there after about 18 hours including 20 minutes suffering heat, noise and vibration created by the working engine? If the mice were dead when he saw them, while I was driving several miles , the engine chatter and inertia of the moving body of the car already threw away dead mice into the road, how could he see them still there? His saying contradicts the facts.
