2019 Chevrolet Colorado Driver assistance Problems

VIN: [XXX]. 2019 Chevy Colorado, ~115,000 mi. FAILED COMPONENT: Vacuum pump failed internally; debris damaged the exhaust camshaft. Pump is cam-driven with no shear pin, so seizure cuts brake assist AND sends metal debris into the engine. Truck/parts are at Chapman Chevrolet, Tempe AZ, available for inspection. SAFETY RISK: On XXX, brake pedal suddenly lost assist while my son merged onto XXX from [XXX]. Pedal effort/stopping distance increased with no warning - high risk of collision merging into highway traffic. CONFIRMED BY DEALER: Yes. Chapman Chevrolet confirmed vacuum pump failure and camshaft damage, consistent with GM TSB 21-NA-268 (drive-lug failure). OTHER INSPECTIONS: Dealer only so far; not yet by GM, police, or insurance. Available if needed. PRIOR SYMPTOMS: None. There were no warning lamps, messages, or other symptoms prior to the sudden brake assist failure on 7/1/26. This is a known failure mode on GM's cam-driven vacuum pump (TSB 21-NA-268; Special Coverage XXX covers 2014-2017 trucks/SUVs but not this 2019 Colorado despite same design). Requesting investigation into whether this is an unaddressed defect on 2018-2019+ Colorado/Canyon 2.5L trucks, and whether recall/extended coverage is warranted. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My radio is hooked up with my reverse camera, it has been malfunctioning for about a year now. When I place my truck in reverse and the reverse camera comes on it only displays it for 3 seconds than turns immediately off. This is causing a safety issue. I depend on this radio and camera to work properly. They dealer have to assume responsibility over this matter.i took my truck the dealership right 104 thousand miles, the dealership is charging me humongous amounts of cash to have the safety concern fixed.

We purchased a 2019 Chevrolet Colorado December 2022. Beginning in January 2023 to current month July 2023 the vehicle has been at the dealership 4 times for the same occurrence: SERVICE STABILITRAK and ENGINE POWER IS REDUCED A warning “ding” sounds (the same noise as seatbelt, door ajar, etc) simultaneously with the messages “SERVICE STABILITRAK” and “ENGINE POWER IS REDUCED” The vehicle immediately is jerking or lurching, the engine no longer runs smoothly and is misfiring. The engine power reduced does not allow safe acceleration, and the vehicle is unstable (as it moves it feels like driving over a thousand speed bumps over and over), the engine misfiring is heard from the exhaust and the vehicle is visibly vibrating, on acceleration the maximum speed is 20 mph. All 4 times this has happened while driving the vehicle on highways in traffic. We are left unable to get out of the way of moving traffic, unable to accelerate, change lanes or make turns safely. Three of the four times we had the vehicle towed to the dealership. The last time the vehicle did this fortunately I was near our local dealership and drove it less than a mile so the service people could “witness” what I had been trying to explain what’s been happening with this vehicle. This is a very serious issue! My husband is 75 and very ill. I have to drive him 100+ miles for treatments on a regular basis. We cannot continue to be put in danger because of this vehicle default. We need this problem fixed not only for ourselves but for the safety of others, including unsuspecting drivers and innocent passengers, young, elderly, disabled, some simply misunderstanding our vehicles “failures to perform” in traffic on the roads. A trusted vehicle is very important. A stabile vehicle with sufficient engine power is a must if we are going to put it on the roads. “SERVICE STABILITRAK” and “ENGINE POWER IS REDUCED” is not new. General Motors needs to take action to correct this problem and educate dealers.

* The touch screen went blank. After inspection by Dealer, it was discovered the radio failed causing this event to occur. * Without this component, the turn signals did not work properly, the seat belt warning did not sound, there was no access to rear camera, and rear cross traffic warnings and back-up camera did not work. In addition, access to On Star did not work for any emergency situations. * Dealer confirmed the radio caused this issue. * Only the Dealer inspected the vehicle. * There were no warning lamps, messages, or other symptoms of the problem prior to the event occurring. It happened after starting the vehicle one morning (April 25, 2023). Additionally, the light on the touch screen remained on when the motor was turned off, causing drain of the battery and leaving me stranded. I had to call emergency services to help me. I had to purchase a new battery because of this along with the purchase of a new radio component as well as pay for re-programming of the system. Total cost of this incident was $1,400.71. It should also be noted that the vehicle only has 65,000 miles on it.

The stabitrac system malfunctioned and went into low power mode while on the highway almost in an accident because of speed loss. The button to turn it off did nothing. Still unsure what caused this to malfunction but needs to be a way to override to maintain speed without power loss

Forward collision goes off on its own for no reason, my ac went out at 4000 miles and cemetery froze over, my rear third brake light leaked at 5 months old and ruint my headliner and they wouldn't fix it without me paying, and now I am experiencing the shudder from my transmission that appears to be a common issue with all the trucks chevy put out. I also feel as if they will find a way to not cover this as I am out of warranty

My rear-view camera does not work anymore and displays a blue screen. It is available for inspection. Happened after the weather turned colder. Vehicle has 38,000 miles and dealer won't cover it. Potential problem of running into someone behind me while backing up. No previous messages until the problem occurred. I understand that there are a lot of GM vehicles with this issue.
