This isn't normal take it back. Pedal should stay firm. Like you said you probably need a new master cylinder.
My mother's 2017 Trax failed to go into drive or reverse after she backed out of an incline. She could move the gear shift but the vehicle would not go into forward or backward, this lasted for about 30 minutes. She recalled that about 2 weeks prior, the vehicle hesitated to go forward while in Drive at a stop light. The dealership and Chevy Customer Care attribute the incident to a failure on my mother's part to press on the brake pedal while backing down the incline. I do not believe that she did not have her foot on the brake. Just wondering if anyone has experienced this and has a more definitive answer as I do not know if my mother is safe driving the vehicle.Post about any issues/problems you have experience with your chevy trax in this thread.
Most GM vehicles are designed to slightly pull right. Just in case someone falls asleep at the wheel, the car will slowly drift right into the ditch.Yes, My 2016 trax pulls to the right. When I took it back to the dealer they said it is normal, but my mechanic says the problem stems from the front wheel drive torque.
