I was in stop and go traffic; when the car in front of me stopped suddenly, I tried to brake. I was far enough back that I should have been able to stop in plenty of time. My brake pedal froze and would not depress (brake pump failure). There were no warning light prior. The car has less than 28,000 miles and relatively new tires.

Was approaching an intersection with a stoplight that was red. Another car stopped at light. Applied brakes, but car slowed down only slightly, no matter how hard the brake pedal was applied. It was like braking on black ice, even though the cars wheels were still going around. Rear ended the car at the light. Suspect that computer was telling the car to try to charge the battery using the forward motion of the car instead of stopping the car. All air bags deployed. Injuries were limited to bruises, abrasions, and general body soreness. Vehicle currently in possession of Allstate Ins. Have requested that brake system be inspected, and computer info be downloaded. Car was totaled. No injuries in other vehicle. No previous problems, no warning lamps or messages prior to accident. Car had been well maintained, including all recalls, and received routine maintenance (oil change, tire rotation) about three months before the incident. Problem has not been reproduced, nor is it likely to be since the vehicle is undrivable.

Leasing 2019 Chevy Volt from dgdg Chevy: End of September -- major safety issue (brakes): End of September 2019, the vehicle had limited brake power (check engine light on and traction control disabled). When braking, the car makes very loud (system noise) and skids while braking. After nearly crashing the car couple of times in the highway (due to very poor braking), car was turned into Chevy dgdg and problem was confirmed. Car was returned back second week of October and initial issues went away. First week of December 2019 -- more brake problems / risk to drivers brake issue had returned (limited brake power; skids while braking, makes loud beeping noise, check engine light on/traction control off). I bought it back to the same dealership, after nearly rear ending few cars due to the malfunction of the brake. Issue was confirmed and was in the shop for over 70days+. car was returned after replacing the brake system. First week of February 2020, same issue occurred after less than week of receiving my car back (took more than 70days in the shop). Same issue, brakes are not functioning properly, almost rear ended someone again, as a result of it. Shop is taking a look at it again. I'm writing this report in hopes of gaining attention of this major safety issue which is putting my life, and others at risk, working with Chevy. I have the fear that this problem can occur again, based on previous attempts, and no real resolution.
