2021 Chevrolet Colorado problems

“The brake booster vacuum pump broke and caused my brakes to stop working properly while driving on the highway. There were zero warnings from the vehicle I went to press on my brake and it was stuck i luckily was able to push it down enough to safely stop”

“Both rear calipers have become frozen or stuck, causing the brakes to seize and not work correctly. This happened around 53,000 miles. There was a burning rubber smell as well as the tire/brake temp was 5 times the normal. This created a severe driving hazard.”

“The rear differential is sounding very loud, like grinding roaring sound @ 72,000. This truck doesn't pull any loads or anything heavy.all service are on time. How can this young milage truck major part go bad just so. It's dangerous driving on the street. It can cause death if it blows up or freeze. GM has a global service about their miss labeled rear differential. They now acting like they now hearing about this when many people is complaining about this faulted differential.”

“Brake vacum pump experienced a catastrophic failure. I was unable to step on the break because the break pedal was hard. I ran thru a red light. I was told the brake vacume pump shattered & pieces of metal went into my engine”

“I am reporting a serious safety defect involving my 2021 Chevrolet vehicle. While driving, multiple warnings appeared including “Service Power Steering,” “Steering Assist is Reduced,” “Service ESC,” and “Service Battery Charging System.” The vehicle then lost steering assist, braking performance became unreliable, and it created a serious risk of crash. The vehicle later shut down completely and has remained inoperable. The failure appears electrical and affected multiple critical systems at once, suggesting a cascading system malfunction. Since the incident, the vehicle has not restarted or operated normally. I have replaced the battery, alternator, starter, ignition switch, brake vacuum pump, ECM, spark plugs, fuses, and relays, but the issue persists. The vehicle still shows charging system faults and severe battery drain, indicating an unresolved underlying electrical defect. I have found numerous reports from other 2021 Chevrolet owners describing nearly identical failures, including sudden loss of power steering assist, ESC warnings, charging system failures, battery drain, and complete vehicle shutdowns. This suggests a possible widespread defect…”
