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. …
Having issues with braking. Occasionally at high speeds, but more often during lower speeds. The brake pedal becomes very hard to depress and meanwhile the vehicle is still moving, not allowing you to stop. Happens also going in reverse. Had a collision, hit the rear end of another vehicle yesterday morning during rush hour, 3/18/2019. I was slowing down to 15 MPH, due to a red light, but brake pedal would not brake, becoming very stiff, making it impossible to brake, and stopped due to the collision. Luckily no one was hurt. Front body severe damage to my Tahoe. Police report has been filed. We bought this Tahoe in fall of 2017, and February 2017, took into the dealership due to the braking issues, nothing was found or done to the brake system. Tahoe is back at dealership as of today, and nothing has been found, according to Chevy techs
I pulled into my driveway... The engine speed started increasing and simultaneously the brake pedal sunk into the floor and braking abilitywas lost. This happened about 4 feet from my garage door and this caused my truck into the garage door. I have a driveway video of me on the phone and then the car being accelerated through the garage door.
The liftgate malfunction is both bizarre and dangerous. When opened it proceeds to drop about a foot quickly, enough to create serious head contact. It then proceeds to close without use of sensors, repeatedly pinning the operator against the back of the car. Only with strength and agility did my wife manage to slide out the side. We are thankful that the only damage was a bruise on her leg. It could have been much worse for an older, less agile person. It happens when vehicle is stationary, on or off. The dealer plans to replace the liftgate actuator, but it will be at our expense. Chevy has declined coverage because we are not the original owner, we did not buy it from a Chevy dealer and we did not purchase extended warranty coverage. There is no recall outstanding so they have no obligation to help us. …
I live in a fairly arid climate, where rain doesn't occur frequently. A couple of months ago, after my Tahoe had been sitting in the rain, I noticed water dripping from the inside door pillar when I opened the door. I just assumed it was water than came in from the outside when I opened the door. Then about nine days ago, while driving in the rain, water began dripping from the top center console area, in a steady stream. When I took it into the Chevrolet dealer they said that the seal on the hi-frequency antennae (shark fin antennae), over the driver's side was faulty, and that water was leaking in through it. Since there was not a recall for my VIN, and since rain was predicted to continue for several days, I had no choice but to pay $452.32 to have a new antennae installed. …
Tl* the contact owns a 2015 Chevrolet Tahoe. While the vehicle was stationary and while driving various speeds, the front driver's side seat belt severely cut into the contact's body. The seat belt became significantly worn to the point of a potential fracture with the seat belt webbing. Furthermore, the contact stated that the trimming on the front driver and passenger sides became detached from the vehicle's exterior. The trimming created a whistling noise and blew in the wind while driving various speeds. The contact rolled down the driver's window and had to hold the exterior trimming to the body of the vehicle to keep it from detaching from the vehicle completely and striking other motorists. Jupiter Chevrolet (11611 I-635, garland, texas 75041, [phone]) was made aware of the failure and took the vehicle in for service. The vehicle was not diagnosed or repaired. …
I was driving down the highway at about 70 MPH and my wife looked in the passenger side mirror and saw the applique on the passenger side door behind the window (where the b pillar is) was loose and flapping in the wind. I had some tape in the vehicle so I pulled to the side, taped it down, and continued driving. I took the vehicle into the Chevrolet dealer the next day and they said it is a common problem with the Tahoe. The dealer said the design of the applique attachment was poorly done and when they replace them they now use a stronger attachment. The dealer found 2 other appliques loose and recommended replacing them as well before they flew off while driving and possibly causing a safety issue to someone behind my Tahoe.
Tl* the contact owns a 2015 Chevrolet Tahoe. While driving approximately 55 MPH, the plastic molding around the frame of the passenger side door and tended to pull out approximately three inches off the frame, which caused a distraction for the driver. The contact stated that the molding on the driver's side door frame was replaced a year ago. The vehicle was taken to the dealer (k & j Chevrolet, carlyle, il, [phone]) where the molding was replaced on the passenger side door frame. The manufacturer was made aware of the failure and stated that there was no recall. The failure mileage was approximately 34,000. Updated 8/14/18
The exterior side panel that separate front and back of Tahoe threatens to fly off during driving. It's primarily on highway driving from 50+ miles per hour. It's as if wind is getting under them and its always a concern they are going to fly off. We often are stopping and hitting it back in place. If it come off it will be a $130-180 piece each side and cosmetically ugly for our vehicle and a danger to other motor vehicles as a flying object. Please recall this as we are hearing from dealerships it is a common part coming off of the tahoes. It is a common occurrence. It didn't happen just once.
