Will the addition of a CouplerTec system to my vehicle void the manufacturer’s new vehicle warranty? Will it interfere with on-board electronics?

No. There is no reason why a CouplerTec system could ever void a manufacturer’s warranty. CouplerTec complies with the strict testing standards for Electromagnetic Compatibility (EMC) and will not interfere with your vehicle or any of its systems.
