2015 Chevrolet Tahoe complaints

The service break trailer system warning keeps going off when I’m not towing anything. It’s to the point that in a 10 Minute drive it goes off about 10 times. I’ve been to numerous machanics and none of them are able to determine what is causing this issue

Power steering assist, ABS and skid control failed all at once during travel. Also emergency brake light lit up along with these other warnings. Hard to steer. The vehicle has not yet been inspected. Scheduling that now. All dash warning lights lit up along with warning messages just as the failures occurred. Upon restarting the vehicle the failures reset to normal operation. NOTE: The vehicle had been running and idling in very hot temps ~101

I purchased this vehicle a few weeks ago. I was told by the Salesman that everything worked in the car. I test drove it and the lane departure warning was working so I assumed the forward collision would be working. In real life driving, I have nearly run in to numerous cars as the forward collision does not work. In one instance, someone slammed on their breaks, my collision didn't alert me, thankfully I saw it, but I had to swerve off the road to keep from hitting them. In addition, the cooling seats work, but the heated seats do not work on either side of the front seats. Lastly, I have discovered that my Navigation system does not work. I can't get it to change to my current location and the GPS is X'd out. This is what I have so far, but sadly, I feel more things are going to happen with this vehicle. I am working with the dealership on the forward collision and heated seats, but don't know if I will get anywhere with them. They have said they will not fix the Navigation system, which is affected by the CAL (calibration) error message on my screen.

The pressure fuel line on top of the gas tank started leaking while driving and caused large puddles of gas under the car. Parked vehicle and unable to drive it due to gas leaking near exhaust.

While driving down the road at random occasions the “service trailer brake system” warning will alert us by dinging multiple time. This continues to happen more and more frequently. It will ding and alert us over and over again. The longest it has occurred was for about an hour straight. I took a couple videos/videos of this happening. After doing some research online every article I found stated that it is a wiring harness issue. It was recommended that we report this to NHTSA. I should add that we are not and have not every pulled a trailer.

The contact owns a 2015 Chevrolet Tahoe. The contact stated while attempting to park the vehicle, the brake pedal was difficult to depress and failed to respond. To avoid crashing into the vehicle parked in front of her she crashed into the curb. There were no injuries. There were no warning lights illuminated. The vehicle was towed to the dealer and diagnosed that the vacuum pump needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 7,770.

On several occasions the following warnings will pop up. Service Stabilitrack, Tighen Gas cap, Service trailer brake system, Automatic collision prep unvailable, and the check engine light will come on. Then the dashboard lights will flicker on/off, the montior will turn black, the doors will unlock and lock. It has happened when I am going 70 MPH down the freeway. And on several occassions the car engine will turn off/stall as i am either pulling into an intersection, parking spot or coming to a stop. I will take it to the shop and have the check engine code scanned/turned off and it will be fine for a week and then start again

Fuel line leak above the gas tank causing fuel to spray under the rig. Big fire hazard

Fuel is leaking from gas tank area. Major fire hazard. I am told this is due to a faulty fuel line securing issue which allows the fuel line to rub cuasing a leak and major fire hazard.

Technical Service Bulletin 17-NA-304 1..6 should be a recall if it involves a fuel leak. My vehicle has experienced this issue, and fuel is actively leaking (right next to the exhaust). With 2 small kids in the car everyday, and Chevy (and the NHTSA) knowing this since September, 2017, how is this not something that a consumer is notified about, and fixed by the manufacturer immediately? I would appreciate if someone could contact me to talk me through this not being a recall.

Trailer brake system chime goes off constantly. Chevy refuses to fix the defective wire harness. It is distracting and I have no idea if my trailer brakes would properly function if i were to tow. We ranch, but have avoided using my vehicle for this reason. This has happened continuously since 2019.

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.

Airbag picture showed on dash. After several dealership appointments, the code B0014 04 was found. Driver seat airbag deployment exhibits high resistance due to faulty electrical jumper wire connections and may not deploy upon impact.

The contact owns a 2015 Chevrolet Tahoe. The contact stated while driving on the highway at an undisclosed speed, the trailer braking system warning light illuminated. The contact stated that the failure recurred several times. The vehicle was not taken to be diagnosed or repaired. Neither the manufacturer nor the dealer had been notified of the failure. The failure mileage was 123,917.

The contact owns a 2015 Chevrolet Tahoe. The contact stated while driving approximately 65 MPH, the vehicle lost motive power. The contact stated that he depressed the accelerator pedal however, the vehicle failed to respond. The contact stated that the check engine warning light was illuminated. The contact pulled safely off the highway and had the vehicle towed to an independent mechanic. The vehicle was diagnosed and it was determined that the transmission control module and several other power train components needed to be replaced. The independent mechanic related the failure to NHTSA Campaign Number: 14V374000 (Power Train). The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 119,300.

Brake pedal becomes very difficult to press and has nearly caused an accident on numerous occasions. Recall has been issued for other year models of Tahoes as well, but not 2015 yet.

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.

The steering locks up while turning. Also grinds most of the time. The steering shaft retainer in the column fails and allows the shaft bolt to rub on the lower end of the column. Has tsb PIT5312-B. But gm will not cover this. This is a huge safety concern.

Design flaw when fuel line rubs against the tank or frame and causes a hole in the line, resulting in fuel spraying everywhere.

Second Inquiry on this problem, a detailed description was sent previously and no response was ever received. 2015 Chevy Tahoe in short, interior LED lights flash when ever the brake is applied. Interior LED lights flash when left turn signal is activated. Dealer stated that a Service Bulletin was created for this issue as an obvious safety issue at night. Electrical tape over the second seat LED's Dealer wanted at the time $180.00 to remedy the problem. (Documented) Dealer on next recall visit, Customer Service stated that they were unaware of such an issue, and also that this was the first that he had heard of it. Internet is well aware of the electrical issue.

I'm having problems with my brake system. When I'm backing up it will slide like it don't want to stop fully. If I'm at a light and press the brakes frequently it don't want to stop and feels like it slides before coming to a complete stop. On hills it feels like it's harder to keep the SUV stopped without rolling.

Condenser went out mechanic stated there's alot of complains about same issue with the same year make and model of my truck

I purchased a Certified pre-owned Chevy Tahoe, in 2017, for the past year to as of 2/18/2022, the Service Trailer Brake has been chiming. It isn’t continuous majority of the time, but I know it isn’t right and often alarms me when it does chime. I do not tow trailers behind my vehicle at all. I drive to work and home, take kids to school and sporting events. .I would like to know if this has or when will this be recalled? Obviously something is setting it off??

WHILE OUT DRIVNG OTHER VEHICLES WAVED ME DOWN TO INFORM ME VEHICLE WAS LEAKING MASSAVE AMOUNTS OF FUEL. I PULLED OVER TO SEE FUEL LEAKING UNDER VEHICLE. THE SMELL WAS STRONG AND IT WAS POURING OUT AT A DECENT RATE.

“Trailer Break System” warning keeps popping and makes it very difficult to drive safely!

I have had my vehicle repaired and reprogrammed in May 2020 for the recall of increased brake effort and then in august of 2021 the brake booster repaired. It is Jan 2022 and I’m still having difficulty with my brakes almost rear ending or backing into vehicles when parking. This is unsafe. This is a known issue and needs to be resolved. It has been taking me so much effort to stop or it feels as the brakes are slipping not catching.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that the trailer hitch warning light was illuminated with an audible tone. The vehicle was taken to the local dealer however, the mechanic was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not notified. The approximate failure mileage was 73,988.

The trailer brake system alert is going off twice in a row every 45 seconds to one minute. The chiming is highly distracting while driving and seems to be a wiring issue.

After a 7 hour road trip and returning to local stop and go travel in our hometown, the brakes started vibrating and the brake pedal then went hard. It took a severe downward foot thrust to get the vehicle to stop and even then still continued to roll forward a few feet. The brakes remained hard thereafter and not safe to drive- unable to brake at that point. Luckily we were not in traffic at that time or still on our road trip otherwise I am sure there would have been a serious wreck or fatality. Dealership supposedly took care of the recall repair for the vacuum pump previously but apparently their action was not sufficient. What am I supposed to do about it now? Thank you.

Trailer brake service message constantly dinging and you can’t dismiss the message. Dealership replaced a fuse and thought they fixed it and by the next day the message was back and dinging non stop. It is so distracting it’s almost unsafe to drive. Can’t see my speed or anything on my dash because the message will not go away and the dinging noise is unbearable.

Dome lights keep flickering. Not specific to any light. All of them flash sporadically. Looks like a camera flash at night. It is beyond distracting at night and the dealership could not find what is causing it to happen. It is making driving at night dangerous because it is distracting because it can sometimes flash non stop like a strobe light.

Brake assist problems. When stopping/slow braking while being in heavy traffic, or drive thru, the brakes will vibrate and will not come to a complete stop without it rolling, almost into another vehicle. The brake petal will be stiff and the vehicle will continue to roll. This happens a lot, but seems to only happen during stop/start, bumper to bumper situations.

I bought the tahoe from a buy here pay here Its a salvage car from the action The guy who sold it to me said he would fix and never did I took it in to a shop because i almost recked and the transmission i think messed up because of the brakes and steering There is also another car he sold that my friend bought for me to fix because the guy sold it with out airbags

There is a trailer brake warning that comes up, sometimes 10 times in a single mile of driving on the freeway. It beeps very loud and I cannot hear anything else. It is distracting to drive and I am unable to shut it off, I can only dismiss. I am now not sure if I can tow with my Tahoe because I fear there is something wrong with the trailer brake system. It is loud enough that if something else was wrong, I may not be able to hear it happening with the warning sound going off so often. I don't know exactly what is going on but my best guess is that it is either with the wiring, as this happens when I am not towing, or there is a sensor of some sort that is faulty. In any case, I don't think it is safe to tow because of potential hazards of the trailer brakes not working, or even worse, the trailer brakes locking up and me causing an accident.

Vehicle has shut down twice while turning. When action happens the stability controls are turned off, parking assistance is turned off. All lights on dash flash. With this vehicle having electronic steering, I have no control of this vehicle when it shuts down while driving. Dealer could not reproduce actions to diagnose, but informed me to return if it was to happen again.

While pulling forward in a drive thru, slowing to stop, the brake pedal started vibrating and became very hard to press. Came within inches of hitting the vehicle in front of me. I drove to an empty parking area afterwards and was able to reproduce the problem several times. This only seems to happen at low speeds. The brake assist warning light comes on each time this occurs. The vehicle has not yet been inspected by manufacturer or mechanic. I'm filing this complaint because this is a major safety issue. This is not an isolated problem to my vehicle as I have seen that many others have filed the same complaint with the 2015 Tahoe.

Trailer brake system warning light keeps coming on, over 64 times in less then a 2 hour period, and I"m not even towing or using the trailer brake. It's very annoying, loud and can cause a crash as you immediately look down to see why the beeps are coming for

Trailer brake system error keeps showing. And not towing anything or using trailer brakes. Incredibly annoying

Service light saying: “Service Trailer Breaking System” It’s happening randomly and driving me nuts.

At low speeds, mainly backing up, the brake pedal goes soft and the vehicle will not stop. As you push harder, the pedal becomes stiff and you feel the ABS activate. I have read online that this is a common problem with the 2015-2016 GM models. Apparently the vacuum pump is the root cause however many have stated if oil is found, the Vacuum Line between the booster and the pump 3. Brake Booster 4. Master Cylinder 5. Vacuum Pump Belt should be changed as well.

I purchased a certified pre- owned 2015 Chevy Tahoe LTZ on November 2, 2021, after one day of driving the Trailer brake system chime came on without any towing. the trailer brakes stopped functioning. the warning message would not stop chiming this was distracting me from driving. this is potential danger situation to me and to other drivers on the road.

Truck doesn't want to brake have to put both feet on pedal. Almost hit a car in the drop off line this morning at school. When braking it skips a beat and I have to press hard to try to stop it. It scared me because there's no warning lights, it just happened out of nowhere and was afraid to have an accident home very scary. No it has not been inspected by anyone yet. Yes its available for inspection anytime as I wont be driving till I figure out the problem to avoid a serious accident.

While in reverse, at a slow speed, my vehicle still rolls while pressing the brake. I almost hit my daughter’s dance studio. It’s happened many times now and after checking, there is a recall on the software but not the part to fix this. Apparently the software doesn’t fix it because my vehicle software has been updated. I can’t help but think I could’ve backed into a child at her dance studio. Very dangerous for my family and others. Also it’s frustrating to not feel safe driving.

On 10-9-2021 was driving slowly 5-10 MPH in a parking lot and pressed brake and the brake pedal was very hard to press down. Had to really press it hard to stop the 2015 Tahoe LTZ. Had the Tahoe towed to Firestone and they said it was the vacuum pump. Wanted to make sure there was not a recall on the vacuum pump.

2015 Tahoe with a very stiff ride. ASE certified mechanic who uses OEM parts says front struts and rear shocks are frozen and have to be replaced. Cost is $3600 and he says all parts are on backorder as this is a common failure. The ride is so firm that the car leaves the ground when riding over bumpy roads.

I was driving at 55 mph when the entire car shuddered and very loud babgihg and knocking occurred. Immediately the car slowed way down and lost power. Luckily I was able to sagely move it out of the lane before getting rear ended but that was only because I was in the right lane. The check engine light came on and started blinking and the traction control failure and safety radar system failure light came on. The vehicle was towed to a Chevy dealer and found out the lifters had failed and these damaged the crankshaft. The truck has 91000 miles. After researching there seems to be a very large problem with these engines failing due to the AFM system that chevy uses

The contact owns a 2015 Chevrolet Tahoe. The contact stated while driving at undisclosed speeds, the contact noticed that while activating the turn signals, the lights were blinking continuously with an unknown warning light illuminated. The contact parked the vehicle noticed a lot of moisture and condensation in the lower half of the driver’s and passenger’s side headlights and turn signals. The contact took the vehicle to an independent mechanic who inspected the vehicle and attempted to replace the bulbs for the front turn signals lamps however, the failure reoccurred. The contact took the vehicle back to the independent mechanic to be diagnosed. The contact was informed that the headlight assemblies needed to be replaced. Additionally, there was rust in the plug for the turn signals due to condensation. The vehicle was repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 54,000. Consumer stated light bulbs have been replaced 3 times in 1.5 years.

The trailer brake warning repeatedly alerts - even when not towing a vehicle or in use. This is distracting and has been for some time.

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.

Problem with air Condenser leaking from poorly manufactured part.
