Tl* the contact owns a 2015 chevrolet colorado. While driving unknown speeds, the brake pedal was stiff and failed to respond. Additionally, while the ignition switch was in the on position, the vehicle failed to start and the check engine warning indicator illuminated. The vehicle was taken to an independent mechanic who stated that the vacuum booster and electrical system needed to be repaired. The contact called the local dealer (first choice auto, 2966 s cobb dr se, smyrna, ga 30080, (770) 444-0058) and was referred to another local dealer. The vehicle was not diagnosed or repaired. The manufacturer was contacted and provided case number: 8-4597870930. The failure mileage was 102,000.
Alert comes on and power steering fails. Very dangerous. This happened at 70mph in rush our traffic. Stearing is then unresponsive - no power assist. Onstar system describes it as "an issue with the stabilitrak stability control system in your 2015 chevrolet colorado crew cab has been detected." alert goes away after turning the car on off. But you cannot do this on a highway at 70mph. Fault comes again at random times/speeds etc.
Dealing informed us that there was oil contamination in the brake booster. This was reported to gm 1‑800‑222‑1020. In 5 months time we have had this vehicle in for service on the same item. It wasn't until this last time that ron tonkin in portland, oregon called gm and found that bulletin 11-00-89-005 directly discusses the matter. Because this deals with the brakes on the vehicle, this concerns the safety of the individuals.

Truck has 11k miles. When breaking at low speeds, I get a lot of break squeal. This happens driving forward or in reverse. Also, when driving the truck has a hard time shifting and makes a rattling/pinging noise when it is trying to find the correct gear. This happens sporadically when driving slow, fast, uphill, and mostly occurs during acceleration. The shifting issue happens on the freeway as well as city streets.
When driving around 5 to 8 MPH while approaching a turn. Vehicle ran into vehicle in front of me. Pedal went to the floor and when trying to move the vehicle to the side of the road noticed the brake pedal was locked to the floor. Gm engineer diagnosed as power brake booster and bracket. Repairing vehicle at their cost including body damage.
