The braking system malfunctioned. Son was driving it, brake light came on, brakes started sinking randomly. Vehicle is very slow to get vehicle to stop and had to hit brake pedal hard to even get vehicle to slow down. Opened the hood to verify if there was brake fluid, it was low. Put brake fluid in and tested brakes, a pinhole was spraying brake fluid. Took to get a diagnostic of the vehicle. In addition to the pinhole leak, diagnostics showed that where the brake lines attach there is a leak at two of the components/areas, and told the vehicle would need new brake lines. We did not repair it at the place that performed the diagnostic. We are towing it to a Hyundai Dealership for inspection this week 3/21/2024. We have spoken to Corporate and were given a case number. No other inspections have taken place. Brake warning light came on last week. Malfunctioning brakes are a safety risk for everyone.

Driving 60mph on I-5 in May 2021. Dry roads, no wind. Vehicle suddenly surged (as if we ran over a speed bump at 60mph) despite there being no debris nor damage on the road surface. The surge felt like the ABS system triggered a single pulse, and then car completely turned off: no engine power, no radio power, no cabin lightning power, no dash lighting nor warning lights. Toggling the ignition to accessory didn't help. I had steering authority and brake authority. With no engine power, I pulled over to the side of the road. I inspected the exterior of the vehicle and there was no damage. I entered the vehicle and I was able to restart the vehicle normally. I drove it to a dealership and described the problem, they didn't know what it could be and were 30 days out on booking appointments, so I gave up.
