The contact owns a 2019 Chevrolet Blazer. The contact stated that whenever it rained, water would leak into the vehicle from the gasket around the sunroof.

The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 40,000.

The TBS sensor or switch that tells the vehicle when it has been put in park is malfunctioning. It is not allowing me to park the vehicle correctly and forcing me to start and stop the car multiple times before registering that it is in park. Also, while driving it causes the doors to lock or unlock due to sensing the vehicle is in park or not. To my knowledge this is a widespread issue with GM from 2013-2020. The vehicle has less than 70,000 miles and should not be creating a safety concern for my wife or baby. This needs to be looked into and fixed via a recall. The consumer should not have to pay for the cheap part GM used and should not be failing within 3 years of purchasing the vehicle.
Eco stop/ start died three times since I bought car. I am unable to turn off this option and the accident feature starts to break when I’m not near another car. Any Electrical issues cause the car not to start.
Shift to Park message on display displayed when shifted into Park and the ignition has been turned off.
When slowing down (at the end of a street for example) foot is on the brake but the car will jerk and engine revs as if it is trying to still accelerate forward without moving the gas pedal. The rpms increase. No warning lights, vehicle has been inspected. No issue found by dealership.
When placing the vehicle in park and turning off the vehicle there is a message on the dashboard saying ‘shift to park’ and the vehicle will not shut off, and you cannot lock the vehicle due to the error message.
“Shift to park” message comes up on the dashboard when the vehicle is already in park

The affected tires were cured for too long during production.

Remedy: GM will notify owners, and dealers will inspect the tires, replacing them as necessary, free of charge. The recall began March 22, 2021.
