2015 CHEVROLET TAHOE Complaints

Loss of braking effort. Also described as a hard pedal, requiring increased effort to slow the vehicle.

On several occasions at various speeds, both driving straight and turning, my 2015 Chevy Tahoe has turned off. During higher speeds the SUV will turn back on, instantly, by itself but during lower speeds and turning the car has to be manual turned back on by switching into neutral, pressing the break, and pushing the start button. The most recent time this has happened, it was dark outside and I was turning. I lost everything including my head and tail lights so it was hard for oncoming traffic to see me. I also almost hit someone coming in the other lane because I was unable to fully turn due to the loss of power steering. After this happens, I get many warning/action required messages across the dashboard but no check engine light or code have come up. I will be taking it to the dealer but since it does not happen every time the care is driven, I can only hope they can experience what happens.

"Service Trailer Brake System" warning illuminates on dash repeatedly while truck is running. This warning is extremely distracting to the driver, as it does not cease. It indicates an issue with the trailer brake system, which makes it unsafe to tow anything.

Fuel line at tip of gas tank is leaking. I see dozens of complaints online for others who say gas line to close to chassis, plastic and rubbing and causing a leak. I see some caused fires?

The 2015 Tahoe LZ is experiencing harsh ride due to the failure of the factory Air Ride system. This may have been a good idea, but it will not stand up under normal road conditions. There is no recall for this problem. Shocks leak or are bound up (frozen in place) causing bumps to be transmitted to the vehicle body. I have changed tires and the problem is still there. I have driven GM vehicles all my life (70+years) and this is the most trouble I have ever experienced with suspension components of all the GM vehicles I've owned, starting with a 1955 vehicle. A local dealer priced the repair at around $5000.00. I drove a 1983 Suburban for over 300,000 miles and never had any suspension problems, (except for normal brake wear). There seems to be a lot of owners of this vintage vehicle that have experienced this problem. Whether this is a computer problem or poor workmanship, General Motors needs to REPAIR their self-inflected problem. I worked as a line mechanic for a GM dealership in the early 80's. We never had this kind of problems before computers started to be installed on vehicles.

1.) The wire harness between the body control modules are failing. 2.) When I tow my boat I could loose braking at any time. Display of " service trailer brake system" overrides all other displays on console. Repetitive chiming noise is very distracting and irritating. 3.) Yes, I took it back in soon after i purchased it (a lot of money) and the Chevy rep said it probably was something to do with loose wires concerning the towing. I showed them a picture of the the warning display that I took immediately. They supposedly plugged in a diagnostic reader and said that since the code was no longer showing that they were unable to determine what precisely the issue was, but it was safe to drive. 4.) Component was not inspected by anyone. I was told that if it came on and I was in the area; to bring it in so that they can see the display. 5.) Yes there was a warning message that showed up multiple times. 1 or 2 weeks after being purchased on 3/11/22. I feel that the Chevy reps know of the issue ( bad wiring harness between 2 of the body control modules) and acted as if the had no clue of the picture of the warning display that I showed them and they were able to tell me it was safe to drive even though they said they didn't know what the issue was. ???? I like Chevy vehicles; it would be nice to see Chevy stand behind their product. This is the 2nd Tahoe that I've owned, standing behind your work keeps and promotes customers.

My magna ride suspension has completely gone out. The front and rear are sagging with no suspension travel at all. According to Google, every Chevrolet and GMC with this suspension has the same issue. Cost $3000 to repair.
