5 /5 Brian Roth: Awesome service you can count on! Before a 2,300-mile cross-country trip, QualTech replaced the engine in our high-mileage 2012 Honda minivan. The drive went flawlessly. After arriving, the car lost power and a local Honda dealer found fouled plugs—again tied to worn piston rings, a known issue. QualTech fully backed their work, coordinated with the dealer, and made sure I wasn’t charged. I’ve trusted them with multiple vehicles and will continue to rely on their honest, top-notch service."
