General Motors, LLC (GM) is recalling certain 2014-2016 Chevrolet Silverado 1500, 2015-2016 Chevrolet Tahoe, and 2014-2015 GMC Sierra 1500 vehicles that may have received an incorrect replacement tensioner cable assembly as part of a previous recall remedy or a subsequent repair. The flexible steel cable connecting the driver's seat belt to the outboard side of the seat may be repeatedly bent over the seat side shield as the driver enters and exits the vehicle causing the cable to fatigue and separate.
A broken pretensioner cable reduces the effectiveness of the driver's seat belt, increasing the risk of injury.

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.

Starting on August 13, 2022, my 2015 Chevrolet Tahoe exhibited a harder than normal start condition prior to a drive of approximately 80 miles home from visiting a relative. The car drove normally on that trip. After that return home I parked the subject vehicle in the garage and emptied it of my belongings. I noticed a fairly strong gasoline smell and inquired with my wife if perhaps she had re-fueled our other vehicle and experienced any over fill. Shed said no, so I left the garage open to see if it would air out of the fuel smell. It did through the course of the afternoon so I closed the garage that evening. The next morning (August 14, 2022) we had an event to get to in the morning and were planning to take the subject vehicle. The vehicle again had a hard start issue and within 10 seconds of starting I could smell fuel while inside the vehicle with the windows up. I immediately stopped the ignition and looking under the subject vehicle. I saw gas flowing down the side of the fuel tank from above and dripping on the floor at a rapids rate of 2-3 drops per second. This continued for about 5-10 minutes gradually slowing down since the the ignition had been shut off and as the fuel pressure in the system was reduced. By the end there was a puddle of fuel about 1 ft in diameter on my garage floor under the vehicle. From that point and after any strong gasoline vapor smell had subsided, I decided the vehicle needed to be moved from the garage and parked on the street. I parked it on the street and decided I would take it to Marty Feldman Chevrolet immediately early in the morning of August 15, 2022, while roads were less busy. There was no warning light or indication prior to the leak. In some quick research, I found several concerns related to fuel line abrasion and fuel pump leaks/failures. Marty Feldman Chevrolet diagnosis/repair costs are documented in this complaint. Components are available for inspection.

Steering, Aug 16, 2022
Six days ago my 2015 Chevy Tahoe had a sudden loss of power steering assist while driving down the road after having to come to a sudden stop. The sudden loss and stop required me to jar to the R side of the road. Later in the evening while driving home from work, suddenly my power steering began to work again - causing the steering wheel to have a lot of "play" in the turning of the wheel. This sudden loss and sudden return of power steering has increased since the first incident and happens more often than not. Every time the loss or return happen to the steering, I feel like I lose control of the vehicle to an extent depending on the speed of the vehicle. I am a single mom with two little children who are constantly with me in our vehicle which concerns me for all of our safety. I have done my due diligence on contacting the local Chevy dealership, GM and even the better business bureau due to not being able to get to the bottom of this and continuously being told there's no recall connected to my VIN. There was a recall previously for the Power Steering Assist Motor Kit in 2015 Chevy Tahoes. According to GM which I contacted today, my vehicle was a part of this recall and the assist motor kid was "fixed" which is why there are no current recalls on my VIN. We were told there was a 12 thousand mile warranty that was placed on this new Assist motor kit however, the same issue is now happening again. In the initial recall, chevy was told that dealers are to replace power steering assist motor kit due to increased risk of crash. Dealers are to service all vehicles subject to the recall at no charge to customers, regardless of mileage, age of vehicle or ownership from this time forward. The fact that I am having the same issue with the assist motor after its already been "replaced" is quite concerning for me, my children and quite frankly other bystanders or other drivers with the increased risk of an MVA. I had an auto body shop diagnose the issue with the same resu

When the vehicle idles for long periods of time in Park or Drive (standing traffic or sub-5mph traffic) the brakes provide no stopping power. Upong shifting into N, and speeding up idle over 2000 rpm for at least 20 seconds, the "braking/stopping power" goes back to normal. Not being a mechanic, but car familiar, it's as if the solenoid at long idles does not provide adequate assist power to effectively stop the vehicle. This has caused problems in long traffic lines on 95 south of DC heading to Richmond when traffic begins moving and suddenly slows there is no braking power unless shifting into idle and rev. It also commonly occurs in snowy traffic when things are moving slow. It also occurs in summer idle situations in parking lots if the car is left running and then attempting to pull away there is no braking power. Frontal collisions are a risk, and generally low speed runs ins. Ive had this checked by Chevy dealer/service shops twice and they claim it is not reproducable. There are no warning lights and all recalls have been serviced. This issue occurs at numerous times since owning the vehicle.

Fuel supply line coming out of gas tank is leaking. Looked up on internet and found this to be a very common occurrence, with several pictures of Tahoe's sitting on the side of the road on fire. This is such a common issue on 2015 models that GM should recall and fix. We can't wait for a recall, I know that takes a lot of time. The Tahoe is my wife's ability to get to work and home, as she is the breadwinner in our family, I am on SSDI for total disability. We need someone or some organization to step up and assist us in getting this problem fixed and since it is a design flaw resulting in a serious safety issue, GM should be held responsible for the repair. Local mechanic found the problem after wife smelled strong odor of gasoline in garage where vehicle is parked, which happens to be directly below our bedroom, thus if a fire started in garage, with my health and mobility problems, we might not be able to escape. This is a serious problem, common with this model and I'm sure you've heard about it several times, please help us.
