Seat belts, frontApr 8, 2021
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.
GM will notify owners, and dealers will replace the driver seat belt lap pretensioner, free of charge. The recall began on May 5, 2021. Owners may contact Chevrolet customer service at 1-800-222-1020, and GMC customer service at 1-800-462-8782. GM's number for this recall is N212330040.

Power train, Aug 25, 2023
The torque converters for the 2015 Chevy Tahoe’s or the 6L80 transmission are failing at a rate not seem on a newer vehicle. Chevy dealerships in my area are backed up for 2 to 3 weeks just to look at the possible problem. The failure appears to be due to poor design of the transmission torque converters. Safety is at risk due high failure rate that could occur at highway speeds and thus making the vehicle stop without brake lights and possible fail in the middle of the highway. At highway speeds this failure could cause serious damage and possible death. Due to the 2 to 3 weeks for the transmission to be looked at by Chevy, I chose to take my vehicle to a private repair shop. Prior taking my vehicle to the shop the shop knew based on the high failure rate that my transmission failure was based on the torque converter but the total damage was not known until the transmission was rebuilt. The transmission torque converter problem was reproduced and confirmed by an independent service center. The Transmission was inspected by AAAA transmission located in Fort Worth. The only warning I had of the failure of the transmission torque converter was accelerating to access the highway and the vehicle started to lose power and shutter due to the lack of acceleration. The luck for me was the highway was not crowded and I did not merge on the highway with the loss of power and possibly getting hit from behind by another vehicle. There were no warning signs of the failure the vehicle just started showing signs of the failure that day. The failure first appeared on June 30, 2023. Attached is the copy of the repair bill and pictures of the metal shavings due to the failure of the torque converter which destroyed the transmission pump. The shavings are steel and aluminum particles.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that while driving at a slow speed and while making a left turn into traffic, the power steering assist malfunctioned and the steering wheel became difficult to turn, causing the vehicle to erroneously drive into a busy intersection. The cause of the failure was not yet determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was 108,000.
Exterior lighting, Aug 5, 2023
I have not had a wreck but the fact that when you press the brake pedal the dome lights blink and when you turn on the left turn signal, the dome lights blink. If you hold down the brake like if you’re at a traffic light the dome lights blink continuously until you let off the brake. Now, during the day, that’s no big problem but at night it poses a serious safety risk. A bright light in your eyes while driving is blinding and a sudden bright light in the pitch black dark could lead to an accident. I called the dealer to ask about it and was told yeah, they knew about it and it would cost me like $550 to repair even though it was a defect that they readily acknowledge.
Electrical system, Service brakes, Aug 3, 2023
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.
Power train, Service brakes, Engine, Aug 2, 2023
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 recall related to brakes in 2019; only consisted of replacing computer chip and they knew that this was not the complete fix. They then issued an “unlimited warranty” on the brakes for people like me.

Transmission issue 2015 Tahoe: When accelerating when entering freeway to merge, or similar, vehicle sometimes experiences a sudden loss of power and lurch sensation -- almost feels like the truck was hit. Speed doesn't increase when needed in crash avoidance maneuver or when accelerating during general driving. Eventually transmission failed. Rebuilt. Has the same issue now.

Condition 1 Some customers may comment on the following condition: • Arattlingand/ortickingnoisethatmaybelouderinsidethevehiclethanoutside. ⇒ The noise may be picked up at the back of the left valve cover, and/or underneath the vehicle near middle of the driver’s door. ⇒ This noise will be noticeable at idle, most noticeable in the 700-900 RPM range. ⇒ The noise may also sound like a lifter tick. ⇒ This may also be called a fuel line buzz or ringing noise. • Whiletherattleisoccurring,theS-shapeportionofthefuelfeedline,rightinfrontof the tank, will be vibrating / rattling. Condition 2 Some customers may comment on a fuel leak. Diagnosis that the fuel leak is originating from the fuel feed line at the molded-in clip on top of tank. Cause The rattling, ticking noise may be caused by the check valve in the low pressure fuel feed jumper line at the engine not fully seating, allowing pressure pulses from the high pressure side back into the low pressure side of the fuel system. These pressure pulses could cause the S-shaped portion of the fuel feed line, in front of the tank, to vibrate and/or rattle If the S-shaped portion of the fuel line rattles over a period of time, the fore-aft motion in the line could result in wear. This wear could result in a fuel leak where the line is secured into the molded-in clip on the tank.

The car's transmission Failed out of no where! I have had the car 22 months and was purchased from the Chevrolet Dealer.

I own this 2015 Tahoe, it has 80,000 miles on it. While I was driving to work, the vehicle lost power as I was in the middle of major intersection. I was almost rear ended by another car. A few seconds later the car began going again. I had no service lights, no warning lights and no check engine light come on. It was running rough, lacking acceleration. I immediately brought it to my mechanic. They did they're testing and found Cylinder# 6 has collapsed. I was told that I will need a new engine at costs of over $8000.00. I have always maintained my vehicle and it's had regular oil changes every 4000 miles. In fact I'm still making car payments, and now I have to absorb this major cost of replacing an engine. When I looked on line to find some information of this Lifter problem, I found thousands of complaints of premature engine failures on these very expensive vehicles. I believe GM or Chevrolet needs to have a solution to this. How can they expect us consumers to afford this costly repair on such low mileage vehicles. Please look into this Manufacturers problem

The car started shuttering and a burning smell occurred. Car was stuck in 1st gear and had had to be turned off in the middle of the road and turned back on. Was able to bring it to a repair shop where they had to remove and repair the transmission before it was Driveable
