Brake Drum Wheel Cylinder Problems of GMC Canyon

*component system failure- master brake cylinder *safety put at risk - as brake system failure means the brakes were not working as they should. *problem has been confirmed by GMC and the dealership as a known issue in new vehicles. *there was no warning or alerts prior to the day 8/23/25. On that day was the first warning lights I seen. *part on backorder for the forseeable future. Given the mileage and being brand new and not having the part possibly for more than 30 days I feel as if I should be given another vehicle as I think it would fall under the lemon law? 2025 GMC Canyon at4 miles-2,417.

Already submitted complaint but needed to edit mileage. *original complaint number-11683406. Component system failure-master brake cylinder. *safety-put at risk as after going to the dealership on 8/23/25 service advisor let me leave with vehicle and said it was probaly safe to drive and probably an electrical glitch. There was no warning/alerts prior to 8/23/25. Taking the service advisors advice I drove it that weekend not realizing my brakes could fail anytime. Took back to dealership on Monday 8/25/25. GMC certified mechanic confirmed it was the brake system cylinder. Part is on backorder for the forseeable future. Given the mileage and being brand newand not having the part possibly for more than 30 days, I feel as if I should be given another vehicle as I had paid off the one I am speaking of 2 weeks ago. Also, I think this would fall under the lemon law if the part goes beyond 30 days from being delivered to dealership and truck being fixed. Miles on truck when first occured was 2371, when left at dealership on 8/25/25, mileage was at 2417. Have pictures confirming mileage and alerts. Called dealership on 8/27/25 asking for a workorder as I was not given one. Stating everything that has been talked about with my vehicle with the service advisor and mechanic. I was told from someone who called me this morning after first submitting my first submission that I need that workorder if things progress further.

Hit 3 deer in high speed collision. My air bags didn't function. Then research online showed I have tikata airbags. Then I noticed my brakes if wet or have ice on rotors, when braking, I get terrible squeaking noise and front end will shimmy or vibrate. Rear brakes too. And my power steering started making noise, like a rubbing sound a few months after I bought truck, though no fluid loss or stiffness in steering. I know these air bags are dangerous, metal parts have killed a few people. Why wasn't I notified by automaker about what airbags were installed in my truck!? I need fixed. I do a lot of mountain driving. I would like them to work properly. And these strange noises really bug me. I can't be breaking down deep into mountain roads when I work or travel. Much highway traveling too. The cruise control has never worked, since two weeks after buying truck. If coming up to hills when set, then as you drive up & down more hills, it will self excellerate! not slow down on declines. Very scary a couple of times. Very dangerous! engine would jump into passing gear. I have the 5 cylinder 3. 5 motor. Automatic, sle extended cab 4x4. Should I go back to dealer to get fixed?.
