What owners report most
Tires
“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”

The vehicle stalled and stopped independently. The contact veered to the side of the road. The contact was unable to restart the vehicle after several attempts. The vehicle was towed to the dealer where unknown repairs where completed. However, the failure reoccurred while driving. Additionally, the contact stated that the vehicle failed to start after several attempts. The contact jumpstarted the vehicle and the vehicle restarted as needed. The check engine warning light was illuminated. The vehicle was taken to a local Pep Boys where it was diagnosed that the failure was associated to the engine control module.
