While driving on the highway I notice the rpm-??s were high and the vehicle wasn-??t going anywhere so I had to pull over from the middle lane to the side of the road I. Busy traffic gladly I mad it over safely without getting hit. After I pulled over the service engine light come on and the transmission temperature was high. After the vehicle cooled down and I was able to me the shifting was terrible it would jerk while shifting. So I called aamco transmission and they said I needed a transmission replacement. This is not the first Chevrolet Tahoe I have had that done this my 2010 Chevrolet Tahoe done the same thing and needed a transmission. The repair cost is at $5500.

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.

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

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. Appears this is part of GM class action lawsuit for transmissions and torque converter issues. Very disappointing.

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. 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

My 2015 Chevrolet Tahoe with 90,000 miles needs a new camshaft and all 16 lifters need to be replaced. There was no forewarning about this huge problem. Literally, one day I was out in my car, and the accelerator suddenly stopped working for a while. Then, all of a sudden there was a hard jerk, and it sped up on its own. When I finally found a safe spot to pull over I went to push on the brakes and the entire car just started shaking. My poor children were terrified as this could-??ve turned into a terrible accident for me and the other drivers around me. I immediately called my local mechanic and was told to bring it in immediately. On my way there the service indicator lamp came on. Upon inspection by my mechanic I was told I need a whole new engine. I have not had it repaired because I cannot afford to do so. I would be more than happy to allow someone to come and inspect it upon request. Apparently this is a huge problem with GM vehicles that GM is completely choosing to ignore.

I had noticed a slight smell of antifreeze/coolant occasionally when the vehicle had aroun42,000 miles. As a diesel engine technition I knew something was wrong.I found a slight leak in thr topleft corner of the radiator were the tubes go into the tank. Contacted GM and was told the radiator was not covered under the powertrain warranty. I would only have to add about a half a quart of coolant every service at 3,500 miles. Looking online I had seen bullitins on the 2014 chevy, gmc, and caddilac half ton trucks and suv's. Now at 77,000 miles its getting much worse and GM won't do anything about it. I have ordered a new Radiator and thermostat at an approximatley $300 dollars. I Know they have a bulletin PI1513A. But GM will not help. thank you.

- Shelocta, PA, USA

I was driving down the road at 65mph, when My transmission blew. I believe the correct term is that my torque converter went out. I basically came to a dead stop in traffic, endangering my life and my children's. My understanding is that this is a common issue with this type of transmission. Chevrolet should be ashamed of themselves for not recalling this item.

- Andrews, SC, USA

While accelerating from a green light the truck felt as if it shifted into neutral leaving me stranded in the middle of a 4 lane highway there was no indication or warning light or sign until after the incident. Only then did the check engine light come on. There was a slight vibration before the transmission failed at 85000 miles. The truck is in the shop having the transmission replaced. I lost total drive control in the middle of a busy highway the out come could have been very bad.

Engine service light came on May 7th during a trip which made the vehicle run sporadically and missing which then caused the traction control light to come on as well. When we took the vehicle to the dealership they said that a lifter had stuck and it had ruined the camshaft. Repairs would be $5800. We took the vehicle to another dealership and they gave us a better price and said that two other vehicles were in the shop in front of our vehicle for the same issue and some were newer 2019 or later vehicles and that this was a common problem because of defective parts. They said that the new parts were better and should work without the same problem. We do not have our vehicle back yet, I expect it back in a couple days because they had to order the parts. If this is a common problem, the dealerships know what is wrong and how to fix the problem, why is Chevrolet not letting owners know and take care of the problem before they fail and we end up with a large invoice. I had a 2007 Tahoe that had an oil consumption problem that everyone knew about and no one tried to get the problem fixed. This Tahoe was purchased to take on trips. The vehicle stays in a garage full time, only has 38700 miles on the engine and I have had nothing but problems since it was purchased. During one trip two spark plugs were dead, had to be replaced. One trip the battery was dead so I had to get a battery maintainer and keep on the engine battery. Trip to Florida the front window leaked and after that one stationary side window leaked. One trip the rear air conditioner did not work the first time it was used because it was not grounded. I have already decided to never buy another Chevrolet product in the future even though i have not used anything else since getting out of college in 1973. Enough is enough.
