Owners report brake pedal going to the floor, especially in the morning, and wheel cylinders blowing out, causing total brake loss. This is a critical safety concern because it can happen without warning while driving.
Complaints mirror brake issues: wheel cylinder failures and loss of braking. A buyer should treat any brake fluid leak or soft pedal as a major red flag.
Owners describe transmission slipping, the car dying while driving, and difficulty shifting out of park. These problems can leave you stranded and lead to expensive repairs.
Reports include engine block leaks requiring full engine replacement, repeated stalling, and electrical system failures. These are costly and can make the car unreliable for daily use.
“IN AUGUST OF 2006 I HAD TAKEN MY CAR IN FOR BRAKES. COMING TO FIND OUT MY BRAKES WERE BAD, I NEEDED NEW ROTORS AND MY WHEEL CYLINDERS BLEW OUT. CAUSING ME TO LOSE MY BRAKES ONE DAY ON MY WAY TO WORK. HAD THE VEHICLE TOWED IN TO HAVE IT FIXED. CALLED THE DEALE…”
“WHEN STARTING THE CAR MOSTLY IN THE MORNING, THE BRAKE FAILED. THE BRAKE PEDAL WENT ALL THE WAY TO THE FLOOR. THE PEDAL WAS ALL THE WAY TO THE FLOOR (LEVEL WITH THE CLUTCH) BEFORE THE CAR CAME TO A COMPLETE STOP. *NM”

Owners of newer Silverados report engine shutdowns while driving, diesel particulate filter soot accumulation, and messages like 'Return to Neutral' or 'Press Start'. These can cause sudden loss of power and dangerous situations.
Complaints include the vehicle suddenly going into neutral while driving slowly, and transmission issues after low mileage. This can leave you unable to accelerate or move the truck.
Owners report sudden loss of normal braking, engine shutoff while driving, and screens going blank. Electrical glitches can affect critical systems like brakes and steering.
Some owners describe a firm brake pedal but reduced braking effect, and the truck shutting off during low-speed maneuvers. Brake problems in a heavy truck are especially dangerous.
“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…”
“My 2026 Chevrolet Silverado 3500 with the 6.6L Duramax diesel has experienced three separate P2463 Diesel Particulate Filter excessive soot accumulation events at approximately 4,300, 5,500, and 10,280 miles. Each event required a Chevrolet dealer to perform…”

Buyer analysis
KIA Sephia or Chevrolet Silverado: which should you buy?
The KIA Sephia has far fewer total complaints but a much higher rate per year (about 228 vs. 823 per year for the Silverado, though the Silverado's data covers ten years). In practice, the Sephia's complaints cluster around severe brake and engine failures, while the Silverado's are spread across more systems but at a lower annual rate. Neither is trouble-free, but the Sephia's shorter data window and high yearly rate suggest a higher risk of major breakdowns.
Key differences
- The Sephia has 455 complaints over 2 years (about 228 per year), while the Silverado has 8,227 over 10 years (about 823 per year), but the Sephia's rate is higher relative to its short window.
- Sephia owners most often report brake and hydraulic failures, including wheel cylinder blowouts and pedal-to-the-floor events; Silverado owners report engine shutdowns, transmission slipping into neutral, and electrical glitches.
- The Sephia has 1 recall and 1 death reported; the Silverado has 101 recalls and 3 deaths, but over a much longer period and larger fleet.
- Sephia complaints include engine block leaks requiring full engine replacement; Silverado complaints include diesel particulate filter soot accumulation and 'Return to Neutral' messages.
- Check for brake fluid leaks around wheel cylinders and any soft or sinking brake pedal; owners report sudden total brake loss.
- Listen for engine knocking or stalling, and check for transmission slipping or difficulty shifting out of park; these are common complaints.
- Test drive at low speeds and in parking lots to see if the truck unexpectedly shifts into neutral or shuts off; owners report this happening.
- Check for dashboard messages like 'Return to Neutral' or 'Press Start', and ask about any diesel particulate filter service history on diesel models.
Before you buy
- Obtain a full vehicle history report and look for repeated brake, engine, or transmission repairs.
- Have a mechanic inspect the brake system, including wheel cylinders and lines, especially on the Sephia.
- For the Silverado, scan for stored error codes and test all electrical functions, including screens and driver aids.
- Ask for proof of recall completion, especially for the Sephia's seat belt buckle recall and the Silverado's many recalls.
- Take a long test drive that includes highway, city, and parking lot maneuvers to check for stalling, shifting issues, and brake performance.
