Owners report the manual transmission shift linkage or cable snapping, leaving the car stuck in gear or unable to shift. This can happen suddenly while driving, creating a dangerous situation if it occurs in traffic.
Complaints include a violent vibration and noise from the front end at low speeds, which may indicate internal engine or accessory drive issues. This can be alarming and may require costly diagnosis.
Owners describe strong vibration and noise in the front end during low-speed turns, such as in parking lots. This suggests worn suspension components that affect steering feel and ride comfort.
One owner reported a complete loss of power brakes at 45 mph, requiring a much longer stopping distance. This is a serious safety concern if it occurs without warning.
“I WAS DRIVING ON A MAJOR 8-LANE HIGHWAY. I SHIFTED UNEVENTFULLY THROUGH THE GEARS, UNTIL I ATTEMPTED TO SHIFT FROM 5TH TO 6TH. AT THIS POINT, I DISCOVERED THAT THE SHIFT LEVER OFFERED NO RESISTANCE AND HAD NO EFFECT: THE SHIFT LINKAGE HAD FAILED CATASTROPHICA…”

Owners report engine shutdowns while driving, sometimes with a 'Return to Neutral' message, as well as diesel particulate filter soot accumulation requiring dealer service. These issues can leave the truck stranded or create hazardous situations.
Complaints include the transmission suddenly shifting into neutral while driving slowly, such as in a parking garage, causing a loss of power. This can be dangerous if it happens in traffic.
Owners describe sudden loss of braking effectiveness and engine shut-offs with multiple warning messages. These electrical faults can disable critical systems without warning.
Reports include a severe loss of normal braking shortly after starting a trip, with a firm pedal but reduced stopping power. This is a major safety risk, especially at low speeds or in traffic.
“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
Porsche Boxster or Chevrolet Silverado: which should you buy?
The Porsche Boxster has far fewer complaints per year (2.6) compared to the Chevrolet Silverado (about 823). In practice, this means a Boxster owner is much less likely to experience a reported problem, but when issues do occur, they can still be serious, such as a failed shift linkage or brake loss. The Silverado's much higher complaint rate, including more crashes and injuries, suggests a higher likelihood of encountering significant reliability and safety problems.
Key differences
- The Boxster averages 2.6 complaints per year, while the Silverado averages about 823 per year, a massive difference in reported problem frequency.
- Boxster owners most often report manual transmission shift linkage failures, whereas Silverado owners report engine shutdowns and transmission slipping into neutral.
- The Silverado has 233 crash-related complaints, 160 injuries, and 3 deaths; the Boxster has 1 crash-related complaint and no injuries or deaths.
- Both vehicles have brake-related complaints, but the Silverado's include sudden loss of braking effectiveness, while the Boxster's include a loss of power brakes.
- During a test drive, shift through all gears, especially from 5th to 6th, and listen for any looseness or resistance changes that could indicate a failing shift cable or linkage.
- At low speeds in a parking lot, turn the steering wheel fully and listen for vibrations or noises from the front suspension, which owners report as a common issue.
- Test the brakes at low speed in a safe area; if the pedal feels firm but the truck does not stop normally, it could indicate the reported braking loss issue.
- During a test drive, pay attention to any sudden engine shutdowns or warning messages like 'Return to Neutral' or 'Press Start,' which owners have reported.
Before you buy
- Obtain a full vehicle history report and check for any open recalls, especially for the Boxster's seat belts, sunroof, axle, and electrical system, and the Silverado's fuel pump and forward collision alert.
- Have a mechanic inspect the Boxster's manual transmission shift linkage and cables, as well as the front suspension components for wear.
- For the Silverado, have a mechanic check for stored engine and transmission fault codes, and test the braking system thoroughly.
- Search NHTSA complaints for the specific model year you are considering to see if the reported issues are common for that year.
- Take a long test drive that includes highway speeds, stop-and-go traffic, and parking lot maneuvers to replicate the conditions where owners report problems.
