2015 Chevrolet Tahoe Problems

The contact owns a 2015 Chevrolet Tahoe. The contact stated that the brake pedal would harden upon depression of the brake pedal as the "Service Brake System" warning light would appear on the instrument panel. As the failure persisted, the vehicle was taken to an independent mechanic the entire brake system was replaced. The vehicle was taken to other independent mechanic who informed him that the brake vacuum assist pump needed to be replaced. The mechanic informed the contact of NHTSA Campaign Number: 19V645000 (Service Brakes, Hydraulic) and referred the contact to the dealer for assistance. The dealer was made aware of the failure and the contact was informed that the recall was closed and was no longer covered. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was approximately 150,000.

The park assist enabled flashed and when I brake it studders or I have to slam on my brakes because my car won’t stop. I see this is a recall on other tahoes but not mine!

The contact owned a 2015 Chevrolet Tahoe and stated that while driving, the vehicle's doors locked and unlocked randomly, the cabin lights flickered, and the doors failed to unlock properly during entry attempts, while the radio randomly selected its own options and the touchscreen occasionally stopped working despite the alternator and battery being replaced. Furthermore, the vehicle suddenly and randomly lost motive power and shut off on main roads, highways, and at stop signs, which caused the dashboard to flash on and off and the power steering to fail completely. When attempting to turn off the vehicle by twisting the key, it refused to shut down initially and triggered a large engine bay fan to kick on, though replacing the temperature gauges eventually resolved this specific shutdown issue. The vehicle has been taken to multiple dealers and independent mechanics, but was failed to be diagnosed. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 250,000.

While driving, the vehicle experienced a total loss of power steering, accompanied by a 'Power Steering: Drive with Care' dashboard alert. The steering wheel became extremely heavy and difficult to maneuver. Simultaneously, the ABS and brake warning lights illuminated. Although I managed to bring the vehicle to a safe stop, a subsequent repair attempt failed to resolve the issue. The vehicle remains undriveable as the intermittent failure persists, creating a severe safety hazard.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the steering power seized. The contact had to use force to pull to the side of the road. The power steering eventually worked, and the contact was able to drive to the residence. The contact took the vehicle for an oil change, and the employee informed the contact about a recall issued by the manufacturer. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The mechanic believed the rack and pinion had failed. The contact stated that the problem is intermittent. As of yet, the problem had occurred eight to ten times. The manufacturer was not notified of the failure. The failure mileage was 155,300.

The failure is believed to have originated in the fuel delivery system, specifically the check valve in the low-pressure fuel feed jumper line at the engine. This valve failed to seat properly, allowing high-pressure pulses to travel back into the low-pressure side of the system. This malfunction caused the S-shaped portion of the fuel feed line near the tank to vibrate excessively against its mounting clip. This constant friction wore through the line, resulting in an active fuel leak. All damaged components remain on the vehicle and are available for inspection upon request. The safety of the driver, passengers, and the public is at immediate risk due to a severe fire hazard. Because the leak is located near the fuel tank and undercarriage, gasoline is being released where it could be ignited by road sparks, static electricity, or exhaust heat. A fuel leak of this nature threatens a catastrophic fire that could result in vehicle loss or personal injury. The problem has been confirmed via a physical inspection that matches the symptoms documented in a GM Service Bulletin (Recall - High Pressure Fuel Pump Leakage). While the vehicle has not yet been subjected to a formal tear-down by a dealer due to the danger of driving it with a leak, the visual evidence at the exact location specified in manufacturer documentation confirms the failure. To date, the vehicle has not been inspected by the manufacturer, police, or insurance representatives. Prior to the leak, the primary symptoms were an audible rattling and ticking noise from the engine bay and underside, characteristic of the pressure pulses described in the TSB. There were no warning lamps or dashboard messages, as the mechanical wear on the exterior of the fuel line occurred outside the scope of the vehicle’s onboard diagnostic sensors.

Vehicle cranked longer than usual, noticed slight smell of fuel. After arriving home noticed fuel smell was very strong and a puddle of raw fuel under vehicle. Fuel line appears to have rubbed/vibrated against the frame of the vehicle causing the line to rupture. Date of incident 12-26-2025. No MIL or warning messages were present. The vehicle has not been inspected by anyone other than myself for this incident. I feel this issue could have resulted in serious injury or death of my entire family and possibly others on the road. The vehicle has not been modified in anyway and is in OEM configuration. We will have to have the vehicle repaired but will document as best we can. I would like to add that after a quick internet search I found this to be a common issue so I was amazed there was no recall on our Tahoe. Thank you.

Either the transmission or torque converter went out, one or both completely failed.

My transmission just randomly went out. I had my car evaluated in December of 2025 and nothing was reported on the transmission at all and as Jan 2026 my transmission went out.

I have a 2015 Chevy Tahoe LTZ I bought used 10/12/2024 with 100,000 miles on it. I purchased it from a family member that took great care of it. Always garaged and kept up with all the maintenance's regularly. In March of 2025, we noticed how uncomfortable and terribly bumpy it was riding. I looked it up and discovered that many people with this "Magnetic Ride Control" installed on many other vehicles had to replace them. I thought for sure this would have a recall. And to my disappointment, it was not a recall. I had to pay over $3000 dollars to repair this, which I don't have. Can you please look into this and make the manufacture or someone accountable for such a terrible design. Thank you bumpy it was riding.

All driver assist functions failing

The 2015 Chevrolet Tahoe seems to be known for thermostat failure. My thermostat gauge while driving would drop from 210 to 160 and stay pinned on 160 and the fans would turn on. I was told by an auto body shop that it seemed to be electric issues. I also had a wire under the car catch fire and the auto body shop said that is why my standing lights would not work in the rear but my brake lights would work. It’s very dangerous that the electrical failure caused a fire to start under the car. Then, I ran into another issue just this week where the vehicle has a cracked AC condenser and is slowly losing coolant. It’s a manufacturing issue because all of them seem to crack and we’re not made with a proper seal. Another electrical issue I have is when I turn the wheel all the way to the left or right, even when the key is in and engine is on, the engine will shut off. The car completely shuts off and then I have to turn the key to the off position and then it will turn right back on. The steering wheel is also losing power steering and gets very tight when I have to make a turn. The fuses for my radio are blown and when you put new ones in, it blows immediately and doesn’t turn on. I have MANY issues with this vehicle and it’s obviously a manufacturer issue. This is not ok for a vehicle to all around have such horrible electrical issues. I have had issues driving over a pothole and I lose my radio screen or my whole dash screen and then the dealer and auto body shops say the electrical work is too in depth for them.

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.

Had to have motor replaced due to faulty lifters which in turn damaged the motor. No, I didn’t check with dealers, independent service centers. However, it was inspected by an independent individual who handles these type of issues on Tahoes, Suburbans, etc. Lifter issues happened in November of 2025. My vehicle is still in the shop at this writing having a new motor installed. I have never been notified of any recall for this type of issue for my particular vehicle which seems to be a common issue. Also had issues with sensors and a/c.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that while driving 65 MPH, the vehicle hesitated and the temperature gauge failed to function as needed, with an abnormally loud sound coming from the cooling fans. The check engine warning light illuminated, and a message about the battery was displayed, and a warning light about the battery was illuminated. The vehicle was taken to an independent mechanic, who diagnosed that the thermostat housing had failed and the wiring to the fan had failed. The vehicle was repaired. Several days later, the contact stated that on a separate occasion, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The check engine warning light was illuminated. The vehicle was taken back to the independent mechanic, where it was diagnosed and determined that the catalytic converter had failed. The vehicle was repaired; however, the same day the vehicle was picked up from the independent mechanic, the check engine warning light illuminated. The vehicle was taken back to the independent mechanic, who diagnosed that the timing chain had failed. The vehicle remained at the dealer unrepaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 165,880.

The contact owns a 2015 Chevrolet Tahoe. The contact stated that while driving approximately 60 MPH, the braking system's failure message was displayed. The contact stated that the vehicle had stopped independently. The vehicle was turned off and restarted and continued driving, but stated that the warning light was illuminated while driving downhill. The contact had taken the vehicle to a dealer, who diagnosed the vehicle and determined that the Electronic Brake Control Module (EBCM) had failed and needed to be replaced. The vehicle was repaired. The contact researched online and related the failure to NHTSA Campaign Number: 19V761000 (Service Brakes, Hydraulic, Service Brakes, Electronic Stability Control (ESC). The contact was advised by the dealer that the recall repair had been completed in June 2020. The manufacturer was not informed of the failure. The failure mileage was 134,916.

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

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.

Driving down highway 86 AZ going south on mile marker 89 there was loose gravel/rock as it hit my windshield it cracked it.

The contact owns a Britax Safety Seat, Model Type: Emblem, Model Number: E1A698A002299, Manufactured Date: 12-26-18. The contact stated that the height adjustment bar had fractured and failed to securely maintain the intended position. The failure had occurred inside the vehicle. The manufacturer was not contacted. The car seat was not replaced.

The passenger seat belt won’t click in sometimes or it will click in and get unclicked on it own. After multiple tries it clicks in most times

I purchased this car previously owned. As I’ve had to drive it everyday. I notice the tires/wheels when turning left or right, when parking …the wheels tend to lock then I must put in muscle to turn and return to a straight position. This has gotten worse to the point I almost ended up on a curb last week. Someone needs to check this vehicle because something is wrong. I keep impuestos with the maintenance but this locking of tires/wheels and then the constant shudder afterwards is dangerous. I’m appalled there is no recall or at the very least a free diagnostic or inspection at a dealer. I already told my family to sue if I die or get hurt in this Tahoe. Totally unacceptable

SEAT MOVES WHEN TURNING CORNERS 90 DEGREES. SEEMS VERY UNSAFE. TOOK VEHICLE TO DEALERSHIP AND WAS 'FIXED', 30 DAYS LATER DRIVER SIDE SEAT MOVES AGAIN!

SUNROOF SHATTERED WITHOUT WARNING OR ANY APPARENT IMPACT FROM OUTSIDE SOURCE. DRIVING ON CLEAR HIGHWAY, 55 MPH

CONTACTS ON REAR WINDOW DEFOGGER/DEFROSTER SEPARATED. FIRST ON LEFT REAR (2017)THEN LATER ON LEFT REAR (2018).

I am having power steering issues. I reached out to Chevrolet and they said in their system the recall was performed in 2019 prior to me purchasing the vehicle in 2021. I should not have to pay for an issue that was recalled. I’m unaware of what was done prior to my purchase of the vehicle in 2021

Vehicle was struck from behind at nearly 75 mph, no air bags went off.

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

VEHICLE BARELY 3 YEARS OLD AND THE AC COMPRESSOR IS BROKEN. BLOWING HOT AIR. CONTACTED GM AND WAS INITIALLY TOLD THERE WAS NO RECALL ON THE AC SYSTEM. AFTER RESEARCHING ONLINE AND DISCOVERING THE CLASS ACTION LAWSUITS AND THE ASTONISHING NUMBER OF COMPLAINTS FOR 2015-2017 CHEVROLET TAHOE'S, WE CALLED BACK AND WERE TOLD OUR VIN WAS NOT COVERED. I FIND IT VERY COINCIDENTAL THAT THE SAME MAKE AND MODEL AS OUR VEHICLE AND SAME YEAR HAVE A DEFECTIVE AC SYSTEM WITH THE SAME DEFECT AS OURS, BUT OURS JUST HAPPENS TO BE NOT INCLUDED. THIS IS MY 3RD AND LAST CHEVROLET TAHOE. *JS

THERE IS A DRONE OR BUFFERING SOUND WHILE DRIVING BETWEEN 40-55 MPH. REGARDLESS OF THE ROAD QUALITY. THIS IS ON A 2015 CHEVY TAHOE LTZ THE DEALER LOOKED AT IT AND SAID IT WAS A TIRE OUT OF BALANCE, BUT IT STILL MAKES THE SAME SOUND. *TR
