Owners report 12-volt battery failures that can make the car undrivable even when voltage appears normal, and ICCU fuse issues where a recall update was performed but the fuse was not replaced. These faults can strand you without warning.
Complaints include shift-by-wire failures where the vehicle won't shift out of Drive or Park, and sudden deceleration with a 'Check Electrical System' warning. Such issues affect basic drivability and safety.
The charge door may fail to open, preventing charging and potentially leaving you stranded if you're far from home. This is a key concern for an electric vehicle.
Some owners report unintended acceleration or cruise control problems, though fewer complaints exist in this area. It's worth checking for any open recalls related to speed control.
“Recall 272 - ICCU Ioniq 6 : ICCU fuse and update were required. Dealership ONLY did update. Did not replace fuse. Vehicle was "updated" for Recall 272 on 2/19/2025. Jenkins Hyundai Service Mgr, Savannah, confirmed on 5/18/2026 that this information is correct…”
“I own a 2024 Hyundai Ioniq 6 that experienced a complete 12V battery failure at under 500 miles of use, despite showing normal voltage levels (12.5V off, 13.25V while attempting a jump). The vehicle was undrivable and could not start, even though the main bat…”

Owners report engine shutdowns while driving, sometimes with messages like 'Return to Neutral' or 'Press Start', and diesel particulate filter soot accumulation requiring dealer service. These can cause sudden loss of power and dangerous situations.
Complaints include sudden shifting into neutral while driving, even at low speeds, and transmission issues that can leave the vehicle unable to move. This affects control and safety.
Reports include severe loss of braking assistance and engine shut-offs while driving, often accompanied by warning messages. These electrical glitches can disable critical safety features.
Owners describe sudden loss of normal braking with a firm pedal but reduced stopping power, and instances where the truck shuts off completely during braking. This is a major safety concern.
“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…”

Buyer analysis
Hyundai Ioniq 6 or Chevrolet Silverado: which should you buy?
The Hyundai Ioniq 6 has far fewer complaints per year (about 32 vs. 823 for the Silverado) and fewer recalls (13 vs. 101). In practice, this means you're less likely to encounter frequent or severe problems with the Ioniq 6, though its electrical issues can still be serious. The Silverado's much higher complaint rate suggests a greater chance of experiencing engine, transmission, or brake problems.
Key differences
- The Ioniq 6 averages about 32 complaints per year, while the Silverado averages about 823, a roughly 25-fold difference.
- Ioniq 6 complaints center on electrical and power train issues like 12V battery failures and shift-by-wire problems; Silverado complaints more often involve engine shutdowns, transmission failures, and brake loss.
- The Silverado has 101 recalls and 233 crash-related complaints, compared to 13 recalls and 4 crash-related complaints for the Ioniq 6.
- Both have serious safety-related complaints, but the Silverado's higher volume and severity (including 3 deaths) indicate a greater overall risk profile.
- Check for any open recalls related to the ICCU and 12-volt battery, and confirm that both the software update and fuse replacement were performed if applicable.
- Test the shift-by-wire system thoroughly, ensuring it engages Park and Drive smoothly, and listen for any warnings about parking brake malfunctions.
- Look for signs of engine issues such as rough idling, stalling, or dashboard warnings like 'Return to Neutral' or 'Press Start'.
- Test the brakes carefully for any loss of assist or unusual pedal feel, and check for recalls related to fuel pump and brake systems.
Before you buy
- Obtain a full vehicle history report and confirm all recall repairs have been completed, especially for the Ioniq 6's ICCU and the Silverado's fuel pump and brake recalls.
- Have a certified mechanic inspect the electrical system and battery health on the Ioniq 6, and the engine, transmission, and brakes on the Silverado.
- During a test drive, pay attention to any warning lights, unusual noises, or hesitation in acceleration or braking.
- Ask the seller for maintenance records and check if the vehicle has been regularly serviced according to the manufacturer's schedule.
- Verify the number of previous owners and whether the vehicle has been in any accidents, as this can affect reliability.
