2023 CHEVROLET TAHOE Electrical System Problems

Since 15,394 miles vehicle has experience multiple system failures upon vehicle startup. 2/24, 2/25, 12/25, 1/26. In all of these 4 instances the brakes become spongy/hard, steering wheel locks, and I am not able to control vehicle. Dash lights up; "Brake system failure - 43mph top speed", "Fwd collision system unavailable", "Service traction control", "Service ESC", "Service steering column lock", "Service brake pad monitor". Dealership has replaced, Telematic control module, Electronic brake control module (EBCM), Serial data gateway module, Park assist module and most recently they replaced the battery and cleared the codes to "fix" the same intermittent but recurring condition. In 11/24 Recall N242447990 was performed, reprogramming of Brake system control module and Serial Data Gateway Module, the exact same issue happened before and after the recall.

I purchased a 2023 Chevy Tahoe in Oct 2025. Since then, I have been trying to figure out how to set up the myChevrolet app. The OnStar button doesn’t work so I called OnStar. After multiple calls, they told me that the account is linked to the previous owner and can’t be transferred because of a faulty telematics communications module. The faulty module is also causing the clock to run slow, which indicates battery drain is beginning. The OnStar module failure poses a huge safety and privacy risk. Safety concerns include battery failure that can cause me to be stranded and the fact that the previous owner has the ability to start my vehicle at any time, even while parked in my garage posing a risk to my family’s health/life with trapped carbon monoxide building up. Privacy concerns include the previous owners ability to track my vehicle, lock and unlock...

When I started my car at home, all of the dash warning lights came on, one after another. I put the car in reverse and started backing out of my driveway. I tried to stop but there were NO BRAKES! I slowly pulled back into my driveway and turned the car off. I had to take off work that day because I didn't dare to drive the car. The next day I started the car up and the check engine light was on. Luckily, I had brakes and I could go to work. Now, a day later, my engine light is not on. I made an appointment at the dealership. They can't get me in until mid February so I'm stuck with this problem, not knowing if the brakes are going to fail while driving. Oddly enough, when talking to a co-worker who has a 2023 Chevrolet Suburban, she recently...

As the owner of a 2023 Chevrolet Tahoe, I am currently experiencing persistent issues with the instrument cluster going dark and a severely malfunctioning GM 6.2L L87 engine. In November of the previous year, I encountered a sudden and alarming loss of engine power while traveling on a multilane highway at a speed of 70 mph. I successfully maneuvered the vehicle to a narrow shoulder, where I remained, accompanied by a Highway Patrol officer, for over three hours until a tow truck arrived. The GM certified dealership informed me that the engine was seized. The mechanics were unable to start or manually turn the engine. Upon removal of the engine’s oil pan, they found metal fragments in the oil. After having undergone an engine recall “fix” three months earlier, which included an inspection and oil service change to a more viscous 0W - 40, a new oil filter, and a...

Truck bucked twice in high-speed lane of the highway, gas pedal went soft and we luckily were able to coast the truck to the side of the highway without getting hit. The truck put itself in neutral when we lost the engine and the truck would not restart. It had to be towed, while me and my two kids stood on the side of a dangerous highway for 45 minutes in the snow. The truck has 52,000 miles, Engine was already replaced at 10,000 miles. It just passed the recall inspection and had the upgraded oil that was recommended.

The car was parked totally normal, went into a store, then came out to start it and when it was put in drive every light on the dash came on and gave a warning for “brake system failure top speed 43 mph” “service traction control” “service esc” “service steering column lock” “service brake pad monitor” “trailer brakes disabled service required”. Shut the vehicle off and restarted with same results. Brakes were inoperable and almost hit the car parked in front of me. Let the car shut down for a couple hours came back and started it and now everything acts normal except there is a Check engine light. Haven’t read the codes yet but am making an appointment at the dealer for warranty work.

The car presented steering lock column issues with repair lights on at 50 miles. Since then, they have repaired the system numerous times and replaced that system fully twice. They also replaced the manual start system and six other pieces of the car over 18 visits to two different Chevy dealerships. The car still reduces speed and stops acceleration, has electric issues in the windows, lights and gate etc.

The engine in my vehicle has experiences major failures in valve flap adjusters, multiple valve failures, valve cover issues, and over consumption of oil by over a quarter in a week and a half of average driving. My safety was put at risk because the engine failure resulted in traction control malfunctions while going 70 mph up hill on a major interstate. This led to extreme shaking which did not stop until slowing down to below 15 mph. Luckily I was a mile from an exit and was able to coast off the road quickly; it was decent enough weather, and I was less than 5 miles from my destination so I could creep between 15-30 mph to not exacerbate traction control alarms. That slow mph did back up traffic behind me. As far as I am aware the problem was likely reproduced by the dealership service tech, which led...

On several occasions while operating the vehicle during inclement weather the windshield wipers intermittently stopped working. Restarting the vehicle several times did not remedy the problem. Once the vehicle was parked for a while the wipers started working again. This vehicle has been to the dealership regarding this issue numerous times and sent back in service with a message from the technician, could not duplicate the complaint.

At a stoplight vehicle wanted to stall out Motor was shaking

The sounds from the radio works only 10% of the time, the radio sound also is what produces the turn signal blinking sound. Additionally there is a scratching noise coming from the speakers almost like a bad signal from the tuner. This is very distracting and a safety concern, especially when the turn signal does not audible make a sound. When I call Chevy they say it will be $300 to diagnose, and if you look online this is a known issue amongst newer model Chevy.

I filled my car up with gas and turned it on and it started shaking. Several warnings popped up on the dashboard screen including, Service ESC, Service traction control, And forward collision system unavailable. My cruise control was disabled I had to hold my foot at an angle to keep the speed at 45-50 mph, Causing it to take 10 hours for me to get home from Austin to Dallas. The check engine light was on the entire time and flashed for the last hour to hour and a half. I was unable to pull over at that time because it was dark And I was in the middle of nowhere by myself. The next day I turned my car on.The only thing on was the check engine light, Is , however , around 1 pm that day it Started doing the same thing. I drove it from My patient's...

While driving on the highway at high speed, my vehicle suddenly shut down and went into neutral. After a few minutes of trying to start it, it started and I was able to drive it home. The following day, on my way to the dealership for an inspection, while driving on a busy street, it shut down again. This time, it wouldn't restart, and I had to call the police and a tow truck to have it towed to the dealership. I was freaking out as I had my daughter inside the car with me. At that point, the vehicle had around 26,000 miles. The dealership inspected it and determined the engine was faulty and needed to be replaced. After the engine was replaced, the vehicle seemed fine, but recently, I've been experiencing problems again. The car struggles to start when it shuts off during stops, using the auto shut-off...

Repeated issues with the infotainment system had to be replaced 3 times to date. The motor blew at 49,000 miles 3 weeks ago. The replacement motor is on back order and it is very difficult to get a loaner vehicle, not to mention having to make a payment on the vehicle that I don’t have to use.

Traveling on the interstate late at night in the winter with my family, which includes small children, a clicking noise began but then went away. No diagnostic lamps came on, everything seemed fine, vehicle responded appropriately. Moments later, on a remote stretch of interstate, we lost power and the engine shut down. The vehicle would not turn back on. We were stranded in the dark on a freezing night.

After getting gas just outside of Pueblo Colorado on [XXX] I was entering [XXX] and luckily I was in the right lane when all of a sudden no power to the vehicle. I was able to make it by inches in the clear on the shoulder of the road. Being [XXX], I had trouble crawling over the console through the passenger side of the vehicle because I could not safely see the traffic on the interstate to exit the vehicle on the driver side. The state police could not come to assist us with any type of traffic control because of other accidents. The BNSF railroad has a mutual aid pack with them when needed in an emergency situation. They were able to come assist us with the red lights for traffic control, and the tow truck arrived and was able to flatbed the vehicle to a GM Chevy dealership....

While driving, without warning my brake system failed and vehicle did not stop when I applied my foot on the breaks. In addition to while driving up a steep incline the engine failed as I was actively applying my foot to the gas pedal causing vehicle to roll backwards. Most importantly i do not feel confident using this vehicle any further knowing that the brakes are Not operating as they should, risking my life and my children’s life is nonnegotiable. Someone help please.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that soon after purchasing the vehicle, the vehicle's lane assist feature would be active with no other vehicles in the contact vehicle's vicinity. The contact also stated that multiple other electrical defects would occur such as the backup camera activating while in drive(D), the instrument panel intermittently going blank, and various other defects. The vehicle was taken to the dealer on multiple occasions where they failed to duplicate the failure. The contact then stated that while driving at 80 MPH, the instrument panel went blank. The contact attempted to pull the vehicle over; however, an unknown turn-off of the vehicle warning message appeared on the instrument panel as a warning chime was also emitted from the vehicle. The contact then stated that the vehicle then came to an abrupt stop where the engine and brakes seized, while traveling at 34...

Onstar Telematics Module failure. Part is on backorder with no ETA. This module failure removes the navigation, Onstar services including safety notifications, clocks can stop working, Android auto/Apple Carplay services are not functional or intermittently working. My vehicle has stalled out at a red light. GM is refusing to cover the replacement saying it is out of the bumper to bumper to warranty but they have so many of these needing replaced they can't say when they will get the parts. Module has been confirmed dead by a mechanic at a private shop and by the dealership. GM states this is under the bumper to bumper to warranty even though it controls parts of the power train and should be covered under powertrain warranty as well.

I am writing to express my deep frustration with a recent issue I have encountered with my brand new 2023 Chevrolet Tahoe (VIN: [XXX] ). Following the expiration of my complimentary OnStar subscription, I discovered that all voice-activated and Bluetooth functions are inoperable unless I purchase a separate wireless plan at $25 / month which I cannot afford. This is a stark contrast to my previous six Chevrolets, all of which allowed hands-free phone calls and navigation functionalities via Bluetooth without requiring an additional subscription. I have contacted two Chevrolet dealerships, spoken with numerous employees, and reached out to OnStar, spending a total of nearly two hours on the phone attempting to resolve this issue. Unfortunately, no solution has been found. My primary concern is safety. Manually operating my phone while driving is unacceptable, and in some states illegal, putting myself and others at risk. Additionally, the lack of hands-free...

Bought new and there was a brake pad sensor message immediately that we took it to the dealer several times for and nothing was done other than clearing the code and giving it back. Was in accident 1/24 and it was found that there was a frayed/damaged wire in the break module and break pad sensor that I feel could have led to the accident

I've had my 2023 Tahoe for 15 months, purchased Dec. 2023 Issue #1. Dash message on start up " Restraint System Needs Service". I noticed small lights overhead (buttons for tail gate, sun roof, reading lamps) were off. I pressed some of them, and dash message went away, and lights came on. Everything worked fine. I've narrowed it down to the passenger side reading light. When dash warning comes on, I press reading light, and whalla! all works fine. This has happened about 6 times over the last year. Issue #2. After driving many hours (9 hr drive, then a 2hr drive, then 4hr hr drive on different days/nights) in rain with wipers in auto mode, using defrost on and off as needed. Suddenly, wipers stop working as well as headlights in auto mode! Scary. Pulled over and waited with engine off. Restarted and still nothing. I was able to...

While driving this rental vehicle in traffic it shutdown and came to an abrupt halt. All lights on the dash were flashing, emergency hazard lights would not turn on. Attempted to restart vehicle with no result. After 2 minutes vehicle dash lights went off and hazard lights were able to be turned on. Vehicle then restarted. While pulling vehicle off the road, brakes were not responsive.

This is a brand new vehicle with a known problem to GM yet they keep selling them and admit they cannot fix it. The audio system, including the blinker sound, is warning systems and hands free phone capabilities do not work properly, if at all. This is a distraction while driving - especially when it comes to phone use. It is deceptive and putting public safety at risk, not to mention costing consumers thousands of dollars. Their built in safety system (onstar) cannot be accessed due to lack of audio rendering it useless in a crash/emergency which is a selling point they tout. I do have video of this occurring. Dealership says they cannot repair and that consumers are just stuck with expensive vehicles they cannot rely on.

The contact owns a 2023 Chevrolet Tahoe. The contact stated that while driving at an unknown speed, the "service safety restraint system", warning message appeared on the instrument panel. The vehicle was taken to a dealer where a diagnostic was performed; the diagnostic showed that there was a defect in the overhead module which rendered her airbag ineffective. The contact was informed that the part to repair the vehicle was on backorder and was given a time estimate of six weeks after the diagnostic was performed. The contact recently called the dealer and was informed that part was still unavailable and that there was no longer an ETA on the part. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was 15,000.

The contact owns a 2023 Chevrolet Tahoe. The contact stated while driving various speeds, the vehicle would shake with the check engine and several other unknown warning lights illuminated. Upon restarting the vehicle, the vehicle failed to move out of park(P) with the warning lights remaining illuminated. The contact called the dealer, and the vehicle was towed to the dealer where it remained. The manufacturer was notified of the failure and provided the contact a case number. The vehicle was not repaired. The failure mileage was approximately 8,000.

Intermittent loss of sound on all electrical aspects of vehicle. Can not hear music, phone calls, blinker, seat belt signal, crash detection sound. None will work. Even after turning off and turning back on issue remains unless vehicle is off for 15-30 minutes then it will reboot !

Less than four weeks after having purchased a new 2023 Chevrolet Tahoe LT the backup and 360-degree surround vision camera system completely failed. The cameras would intermittently flicker or would lose connection all together preventing the driver from being able to reverse having the benefit of the camera vision. The rearview camera screen turns black with a red triangle containing an exclamation point alongside a "no camera" circle symbol. The Chevrolet dealer has inspected the vehicle and has confirmed the camera computer is defective and cannot be fixed - a replacement module with recalibration of the cameras is necessary. The vehicle cannot be driven safely, and thus has been with the dealer now for 18 days, with no time table from either the dealer or from General Motors as to replacement of the failed component. The vehicle had been driven less than 700 miles before this failure occurred.
