While driving at low speeds, I am experiencing difficulty with braking. The brake becomes very hard to press down and it takes me longer to stop. I researched this and came across a recall for a vacuum pump issue. I believe this is exactly what is wrong with my vehicle. However, when I input my VIN into the recall website, it says my vehicle is not included in the recall. How can I get this issue covered without having to pay out of pocket (we were quoted over $700). I fear that I may cause an accident if I am unable to stop.

When trying to brake the Tahoe seems to not want to stop. The Tahoe comes to a rolling stop or like it is in sand trying to stop. It eventually stops but not when you want it to. Happens more at low speeds then high speeds.. no lights have indicated a problem. And doesn’t do it all the time but you as a driver can’t trust the brakes! I have had my mechanic look at it he can’t find a problem because when he drives it the Tahoe won’t do it for him. Hasn’t been in an accident yet

On Wednesday, 11/15/23, I was sitting in my vehicle while it was parked and running for several minutes. After a few minutes, the alert chime went off and the message "Service Trailer Brake System" was displayed on the dash notifications. This alert persisted for several minutes. Since this initial incident, the same alert has displayed 3 or 4 more times, but while driving. It repeats persistently, causing a major distraction, blocking my speedometer, and disabling bluetooth features. I nearly wrecked because of the distraction and have not been able to tow my trailer because of the risk of of the trailer brakes not working. I have an appointment scheduled with my mechanic on 11/28/23 to get this repaired, but have recently learned of several incidents of this same alert from other GM vehicle owners. This seems to be a defective wire harness and needs to be recalled as it is unsafe and renders the vehicle useless for many intended purposes.

While driving the breaks failed to work. Then when I started pumping the brakes again it took longer than normal to respond and I had to press really hard. I was only going a few miles per hour in a parking lot. Now 5 days later it's happening all the time. It's also making a click noise when I press the pedal.

While driving I periodically receive a notification on the dash to "Service Trailer Brake System". The message just randomly comes up with an abrupt warning noise which is a distraction and startles you until it goes away. I don't tow anything with the vehicle. The notification happens about once a month when driving and eventually goes away after a few minutes. I do mostly interstate driving and when the warning comes up, it startles you and you feel the need to pull over immediately. The notification noise is loud and a distraction. I will be taking it to a Chevrolet dealership. I have an appointment late August. This has been going on periodically for months.

Incident

In approximately December of 2015, we purchased a 2015 Chevy Tahoe LT from CARR Chevrolet. We chose GM for the reputation, under the belief if we took care of our vehicle and had it maintained by the dealer, it would last 12-15 years. This was NOT our experience.Three years after we purchased the vehicle, the engine died. We were assured this was an anomaly and GM replaced at "no cost", as it was a "manufacturing error". CARR service convinced me it was “great”, as now my vehicle would last even longer. I did not question and blindly trusted those I viewed as trained, skilled professionals. Fast forward to present time, my vehicle is 7 years old (90,000 mi) and never missed a single service. Out of the blue, the transmission dies. I was initially told this is “normal" and “happens” to a tune of $8400 plus maintenance and other wear and tear for a total of $10,000+. This did not sit well with me and I questioned the validity. I requested that CARR give me a quote to buy back the car and they initially refused to give decent price. I contacted GM to complain. After many more days, I was contacted and offered that GM and CARR would carry 70% of the cost of the transmission. I agreed with intent to sell/trade on my own. After many weeks, I picked up my Tahoe and paid $3,400 and headed back to Lake Oswego. As I entered downtown Lake Oswego on a slight hill, coming to a 4 way stop, my brakes completely failed…. I barely missed careening into the back of a car, as they naturally moved forward. I contacted CARR service supervisor, sobbing and shaking after the events and he immediately arranged for a tow. I then contacted the investigator. After many days, the GM investigator response, “it’s fixed free of charge”. I was told it was “known” that these cars “could” have a problem with the brakes, which is why there was an unlimited warranty should it occur. I expressed that I had zero trust in GM, CARR or the vehicle and expected to be compensated. The contact stated her understanding was that the GM re
