general problems of the 2015 Chevrolet Tahoe - part 1

The contact owns a 2015 Chevrolet Tahoe. The contact stated that on several occasions while driving at various speeds, the transmission shifted hard occasionally, and the vehicle jerked abnormally. Additionally, on one occasion while shifted in reverse(r) the vehicle drove forward. The gear shifter was shifted to park(p) and then reverse, and the vehicle reversed as intended. The contact inspected the transmission fluid, and the transmission fluid level was low. The vehicle was taken to an independent mechanic where it was diagnosed that the torque converter had failed, and the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 157,000.

The transmission out of no where started to hard shift from 2nd to 3rd gear then making noises. Spoke with a mechanic who specializes in transmission he had 2 other Tahoes same year same problem that are in front of mine to work on.

While driving multiple times the vehicle has completely lost power or almost died in the middle of the roadway. It has been taken to the dealership multiple times and they are reporting transmission and catalytic converter issues, however these issues were present at 20,000 miles and taken back to the dealership to be fixed. This is now a reoccurrence of issue and the dealership refused to warranty or fix the reoccurring issue. Loss of power while driving and random acceleration have occurred and almost caused accidents on multiple occasions.

Transmission delays in shifts. Whine coming from transmission as well. New torque converter and thermal bypass installed with new transmission fluid and filter. Truck was diagnosed and it’s okay in Chevrolets computers. This is a scary and unsafe way of feeling scared if transmission will fail.

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. 00.

The contact owns a 2015 Chevrolet Tahoe. The contact stated while driving 30-45 mph, the check engine warning light illuminated. Additionally, the contact stated that while driving at an undisclosed speed at night, the vehicle shut off inadvertently. The contact was able to veer to the side of the road. The contact stated that he opened the hood and moved the battery cables around, and the vehicle was able to restart. The contact stated that the vehicle would temporarily lose electrical power while driving. The vehicle was taken to an independent mechanic, where the contact was advised to add a fuel additive in the vehicle. The contact followed the recommendation and the check engine warning light was no longer illuminated; however, the failure later recurred. The vehicle was taken back to the independent mechanic, where it was diagnosed that the transmission had failed and needed to be replaced. The vehicle was not repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 149,000.

Went to start my vehicle 10min prior to me taking off. Five min into my drive I felt my Tahoe start to lose power stop shifting. Once I was able to pull over to a safe location put the car into park and put the car back into drive and the car will not move.

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 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.

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.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that upon making a turn at slow speeds, the vehicle inadvertently shut off. The contact stated that an unknown warning light flickered on the instrument panel. The contact also stated that the vehicle restarted soon after failure. The contact attempted the notify the dealer of the failure but was informed to call back. The manufacturer was made aware of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 100,000.

While driving at any speed the transmission felt like it was shifting gears into neutral on its own and the transmission has since failed. The vehicle is available for inspection. The vehicle dropped drastically in speed in a higher speed zone which could have caused an accident. The problem has been confirmed at the dealer with an inspection. The vehicle has been inspected by the dealership. There were no warning lights until the failure occurred and there were symptoms 2 weeks before the failure.

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.

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.

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.

The truck vibrates violently when truck I accelerate and feel like I'm losing control of the truck. The transmission is said to have issues with the hydraulic system.

Anda manejando cuando empezó a salir mucho humo por el tablero y la troca ya no respodia no podia ya aselerar y el volante se puso duro me sali DE la carretera marqué al sitio DE emergencia por ayuda pero la Tahoe se quemo muy rápido.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that while starting and driving the vehicle there was an abnormal winding noise detected. The vehicle was taken to the local dealer where it was diagnosed a transmission replacement was needed. The vehicle was repaired. After retrieving the vehicle from the dealer, the contact stated she was driving and the brake pedal was hard and failed to respond to avoid crashing. The contact drove into the curb. The contact called the dealer and informed them of the additional failure and the winding noise persisted. There were no warning lights illuminated. The vehicle was towed to her residents. The vehicle was towed to the local dealer again where it was diagnosed that the vacuum pump failed. The vehicle was repaired. The contact stated that while driving, the vehicle was jerking. The failure mileage was approximately 70,000. The manufacturer was not contacted. The contact stated that the failure was related to NHTSA campaign number: 19v645000 ( service brakes, hydraulic).

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.

Recently I've noticed that when I try to accelerate or take off from stop it does not pick up speed as use to. My engine rpms rise but speed is getting less and less. I've also noticed my transmission temperature is staying between 190-200 degrees which gm has already had recalls over pertaining to this style transmission having issues due to high heat. Vehicle has always had maintenance kept up with and never abused. Have taken to local shop since warranty ran out several times for inspection of transmission well my complaints in regards and have fluid done. Recently I've noticed fluid is needing to be replaced more frequently due to losing viscosity from overheating and being burnt, has the familiar and similar smell of toast being burnt. This is a 2016 Tahoe ltz w just over 200k, yes in some ways a lot but considering the cost of vehicle new/age/synthetic fluids and everything it seems to me the transmission should last longer especially considering it's been maintained. These new vehicles are outrageous and the transmissions are very expensive as well, considering these same transmissions have had recalls from gm I'm a little aggravated and frustrated on how some can and can't. I'm familiar and aware they say it's per manufacturing plant and particular models but confused as to how if the transmission that has had recalls for overheating doesn't comply to all the transmissions that are same type, I think it's bogus n a way not to be responsible for accepting failures n having to replace all parts so gm says it only happened here n with these parts. I guarantee you if someone would take a look at gm shipping and papers they would see it. If a 2016 4l60e had problems it's more than likely all of them in that year had all same parts so therefore all acceptable to failure, its not like transmission maker chose different parts to send to different plants or this get that no thats just b. S. So there not responsible for all of them so they pick plant with most failures.

At 123,000 miles the torque converter failed and caused a cascading failure through the transmission leaving me stranded in traffic. Vehicle towed to phoenix transmission in weatherford. 5k later I have a new upgraded transmission with a warranty. Owner says they get about one a month in with the same issue.

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.

I received a combination of three error messages on the same day and they show every time I start the vehicle. “stabilitrak” service needed, “steering assist is reduced, drive with care” action required message, and “rear parking assist symbols unavailable” error message when in reverse. Causes hard/lurch changes in gears. Affects the control of the vehicle and the ability to drive in a straight line.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that while driving from a complete stop and while driving at various speeds, the vehicle made an abnormal whining sound. There was no warning light illuminated. The vehicle was taken to the local dealer, where the transmission was replaced. The contact stated that after retrieving the vehicle from the dealer while driving 10-15 mph, the brake pedal was depressed but was significantly firm and failed to respond. The contact drove into a curb and struck a parking sign pole. The air bags did not deploy. The contact stated that the failure exacerbated pre-existing injuries. The dealer was contacted and advised the contact to restart the vehicle and depress the brake pedal to verify whether the brake pedal was operable. The contact followed the dealer's instructions, and the brake pedal responded as needed; however, the vehicle was towed to the residence because the contact was concerned about driving the vehicle. The vehicle was then towed to the dealer, where it was diagnosed and determined that the vacuum pump needed to be replaced. The dealer replaced the vacuum pump; however, the failure recurred while driving. The check engine warning light was illuminated. The vehicle was taken back to the dealer, where it was diagnosed and determined that the lifters had failed. The vehicle was not repaired. The vehicle was taken to a second dealer, midway Chevrolet plainwell auto dealer (381 12th st, plainwell, mi 49080), where it was diagnosed that the fuel pump wires, the transfer case oil and seal, the engine oil coolant hose, the valve cover gasket, and other unknown parts needed to be replaced. Additionally, the dealer determined that the ball joints needed to be replaced, and an alignment needed to be performed. The dealer also determined that the air ride compressor was noisy. The vehicle was not repaired. The vehicle was then taken to a third dealer, heritage Chevrolet, inc. (350 w dickman rd, battle creek, mi 49037), where it was diagnosed with an oil leak.

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. 00. 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.

Front and rear shocks had to be completely replaced. 2 weeks later the transmission completely went out and have to be replaced. This vehicle has only 80,000 miles. ## #vpic# 1 - check digit (9th position) does not calculate properly #vpic#.

I purchased a used 2015 Chevrolet Tahoe with about 140000 miles. After driving the vehicle for about a month I began to experience problems with the radio. It had an issue playing clearly. Then the display screen started jumping and moving through different commands on its own. Just recently, two months after owning the vehicle, it has started to cut off completely while I am driving it. The first time it occurred is when I was about to make a left turn. The second time it occurred, I was backing into my drive way. This time it cut off completely three times in a row. I think I purchased a bad car and now I'm stuck with it until I can get enough money to sell it or trade it for another vehicle.

2015 Tahoe with 120000, transmission is shuttering and slipping unbelievable. Pretty much everytime it shifts it doesn't know what it wants to do. This is completely unexceptable.

Since purchasing my vehicle in 2016 I have had multiple issues. I have always noticed a drip of oil in my garage that wasn't consistent and when telling my dealership about it they stated they would look into it and found nothing. I was driving down the road and the side door black fascia flew off, the dealership replaced 3 stating it was still under the 34k warranty. I had requested they replace/secure the 4th and was told it was fine and didn't need replacing. I returned for an oil change about 6 months later and reported the one that was not replaced is now loose and was told by the dealership I was out of my warranty period and would be charged an hour labor as well as parts, costing roughly $120. 00. I then had my ac go out in summer of 2019 and had that replaced supposedly a recall. When I took my car to the dealership for an oil change in fall 2019 I mentioned my car was not stopping properly while braking and they informed me there was a current recall that would fix the issue and that was performed. I was still noticing the braking issues. In Nov. 2019 I started to experience misfiring with the transmission and not shifting correctly. I made an appointment with the dealership and on the way to the dealership it worsened and I had to get it towed. I was informed I would not get a loaner car as all of theirs were out to people with parts required without an eta from gm. I was called 4 days later as I had not heard back and was told my car needed a replacement transmission as well as a new vacuum pump as this had failed and is the reason for the hard braking. The transmission was replaced and I was told to pick up my vehicle because the vacuum pump is on back-order without an eta and "I still have my abs that will assist with stopping".

My truck was in 2 wheel drive(wd) and automatically engaged itself into 4wd on its own. , I immediately received a notice on my dash consul, 4wd service alert on my 2015 chevy Tahoe ltz. I was on the highway doing the speed limit 70 mph when my truck automatically engaged itself into 4 wheel high almost causing me to loose control on my vehicle. If I were on snow or wet roads I surely would have lost control of my vehicle at a high rate of speed. I immediately took it to brodheadsville chevy for repairs on 26, December 2019. The dealership put my truck on the computer and determined that it had a code c0398 for range position correction. The repair for this was a new calibration (basically update the current software) to the new version which was (version 9. 2). (see attached dealership paperwork which details the repair. ) I feel this software glitch is by no way my fault nor my responsibility to pay for this software failure. There was not any part found faulty or replaced. Computers were not damaged nor harmed in any manner to create this issue. This was a software glitch or error. The dealership had no explanation as to why or how this happened. I as a user of Chevrolet's product have no control of how chevy codes there software to make sure that it performs correctly. If there is a coding defect in there software there is absolutely no way that I can repair it with out going to the dealership and having them fix it. I would like to see a recall on this unsafe issue potentially causing lose of life.

My 2015 Tahoe began hesitating when I pressed the gas pedal leading me to believe I had purchased some bad gasoline. This continued for two weeks without any warning lights coming on. I decided to take the vehicle to be checked by an automotive place and as I was driving a warning light finally came on. They hooked it to computer and referred me to a transmission specialist located three miles away. The car broke down in a construction zone on the way to the transmission shop. My 2015 Tahoe only had 107,000 miles on it and the transmission had to be replaced. The transmission shop stated that they had seen about four other Tahoes of the same year that had to have transmissions replaced. It ended up costing me $3300. 00 to replace the transmission. I think had a warning light been activated two weeks before I may could have taken it to the shop earlier and had it repaired instead of replaced. This seems to me way too soon to have to replace a transmission in an automobile.

Transmission completely went out at 104,000 miles, requiring new transmission. Entire air conditioning system had to be replaced today the brakes stopped working suddenly- waiting for diagnosis. Vehicle had to be towed. Almost in three different accidents trying to get somwhere and get stopped. Catylatic convertor needs to be replaced and currently has three codes related to it showing. This vehicle has been problem after problem since day one.

Brakes randomly started not working. A lot of resistance, unable to stop, unable to push brake to floor. Finally got somewhere and parked after avoiding three accidents, vehicle had to be towed. Brake booster is bad. This seems to be a common problem with the 2015 Tahoe. Why hasn't this been a recall????.

Power steering went out while driving and gm won't replace under other power steering recalls had to pay 3k to fix, also steering assist out as well and won't fix unless paid for.

Vacuum pump failed on freeway at low speed. Chevrolet has acknowledged there is a problem but only offers replacement for under 70,000 miles. I am at 80,000 miles and had to pay $800 on my vacation trip.
