And because CarShield has a high mileage limit, you can rest assured that your car will be protected for years to come.
Onust Warranty is a vehicle service contract provider headquartered in Scottsdale, Arizona. Founded in 2023, they focus on extended coverage options for drivers seeking protection after their factory warranty expires. Their plans are available for many newer and used vehicles and feature benefits such as roadside assistance, rental car reimbursement, and nationwide repair facility access. One of their most notable features is unlimited mileage coverage, allowing eligible vehicles to remain covered without a mileage cap while the contract is active. They also offer exclusionary coverage options, which generally provide broader protection by covering most vehicle components except those specifically excluded in the agreement. Some plans are available with a $0 deductible, helping reduce out-of-pocket costs when covered repairs are approved. Onust Warranty holds an A+ rating and accreditation from the Better Business Bureau. Customer feedback is currently limited, with only a small number of reviews available across major platforms such as Trustpilot, Yelp, and the BBB. The available reviews generally praise customer service, claims support, and coverage value, though the low review volume makes it difficult to assess overall customer sentiment. Readers interested in long-term vehicle protection may want to explore the details of their coverage, costs, benefits, and contract terms more closely.
