The picture
Is the Hyundai Ioniq 5 or Chevrolet Silverado more reliable?
A plain-English read on what the NHTSA record says about living with each vehicle.
Hyundai Ioniq 5
The Hyundai Ioniq 5 is an electric crossover that owners report can suddenly lose propulsion while driving, often with warnings like 'Stop vehicle and check power supply.' Many complaints center on the Integrated Charging Control Unit (ICCU) failing, which can leave the car inoperable and requiring a tow. There are also reports of 12V battery failures that cause the car to stop completely, sometimes without working hazard lights. While the Ioniq 5 has fewer complaints per year than the Silverado, these electrical issues are serious and can happen without warning.
Chevrolet Silverado
The Chevrolet Silverado is a full-size pickup with a high number of complaints, especially about the engine and powertrain. Owners report sudden loss of power, stalling, and transmission issues, sometimes at low mileage. There are also concerning reports of brake failure and electrical problems that can affect steering and braking. With over 500 complaints per year on average, the Silverado shows a pattern of reliability issues that could be costly and inconvenient for owners.

Owners report sudden propulsion failure and complete loss of power while driving, often linked to the Integrated Charging Control Unit (ICCU) failing. This can leave the car inoperable and require a tow, and in some cases, the 12V battery fails, causing the car to stop with no warning lights.
The vehicle can lose all power while in motion, with warnings like 'Stop vehicle and check power supply.' Some owners experienced stuttering and loss of power after fast DC charging, especially in hot weather, which can be dangerous on highways.
The drivetrain can have issues that cause a stuttering movement when accelerating, and in some cases, the car becomes inoperable. This is often related to the ICCU or other electrical components, not the traditional engine.
“On June 13, 2026, my 2024 Hyundai Ioniq 5 experienced a sudden and dangerous propulsion failure while in active motion. The vehicle had approximately 9,447 miles on it and was at 58% battery charge at the time of the incident. The vehicle was leased in Januar…”

Owners report severe engine problems, including sudden loss of power and stalling, sometimes with the 6.2L motor. Diesel models have had repeated Diesel Particulate Filter (DPF) soot accumulation events, requiring dealer service multiple times.
Transmission issues are common, such as the vehicle suddenly going into neutral while driving, which can be dangerous. There are also reports of loss of motive power, which can happen at highway speeds.
Electrical failures can cause a sudden loss of braking and steering, as well as loud pinging sounds from the engine. These issues can lead to a complete loss of vehicle control, making it a serious safety concern.
Owners report sudden, severe loss of braking effectiveness, even though the brake pedal feels firm. This can happen without warning, increasing the risk of a crash.
“I purchased the 2026 Chevrolet Silverado with a 6.2L motor "new" from the dealer with 5700 miles on XXX. Roughly a month and 2500 miles later, my family and I were in the vehicle, 750 miles from home, returning from a vacation to [XXX] from the [XXX]/[XXX] ar…”

- The Silverado has more recalls (100 vs 21) and more crash-related complaints (117 vs 26), suggesting a higher safety risk.
- Check for any history of ICCU replacement or 'Stop vehicle and check power supply' warnings, as this is a common failure.
- Inspect the 12V battery condition and ensure it has been replaced if needed, since failures can cause sudden stops.
- Look for signs of engine stalling or transmission issues, such as slipping or sudden neutral, and ask for service records.
- Test the brakes thoroughly, as some owners report sudden loss of braking effectiveness.
Before you buy
