When applying the brakes or using the left turn signal, the interior lights in the first, second and third row flash. This is extremely dangerous while driving at night.

- Meridianville, AL, USA

Back interior lights flash on when driving, very dangerous at night. Does it when use breaks. Moving or stationary. All the time.

- Underwood, ND, USA

The interior dome lights flicker when applying the brakes and also when using the left turn signal. This happens whether the vehicle is stationary or in motion.

- Canton, GA, USA

If you press brake or use left turn signal overhead dome lights flash on and off. It occurs all the time.

- Poplarville, MS, USA

While driving the vehicle's driver seat will move forwards and backwards making it unable to reach pedals to stop safely, air bag light will flash erratically, loud ticking noise, miss-fire/vibration while idling. Been to the dealership twice to fix still not fixed, contacted GM about issues and to file a complaint. Now dealership refuses to work on Tahoe

- Clever, MO, USA

2015 Chevrolet Tahoe. Everytime the brake pedal was depressed, the interior lights in the vehicle would illuminate and flash causing blindness at night. This happens when stationary or in motion. Spoke to dealer who stated they never heard of issue. Provided them with a possible tsb #P11268 from alldata. This has occurred at least 50 times

- Saint James, NY, USA

The contact owns a 2015 Chevrolet Tahoe. While driving at various speeds, there was an unknown error code that illuminated on the instrument panel. The vehicle was taken to the dealer for diagnostic testing; however, the failure could not be duplicated. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 5,000.

- Waldorf, MD, USA

The interior lights over the rear passenger seats and the cargo area blink when the brake pedal is pressed. This also occurs when the left turn signal is applied. The brake control module was replaced once and the issue seemed to go away. It has now returned and the dealer is telling me that the lamps need to be upgraded.

- Lucedale, MS, USA

The contact owns a 2016 (na) Chevrolet Tahoe. While driving approximately 10 mph, the service front camera warning indicator illuminated and the instrument panel failed. The vehicle was taken to the dealer where it was not diagnosed or repaired. The manufacturer was notified of the failure. The VIN was unknown. The approximate failure mileage was 66.

Although the vehicle was sold with the capability for dingy towing using the optional transfer case as per the last 3 generations of Tahoe's, it became apparent a design issue was present the first time I put the case in neutral and turned off the car. I advised the GM dealer and a month later they changed the procedure calling for battery disconnection. This results in the loss of all information. The first time I dingy towed the car using GM procedures my only key fob unsynced with the vehicle when the battery was reconnected. This left me with the truck in neutral connected to my bus with no way to disconnect it. It is not possible to back up with the vehicle connected to the bus and there was no room to turn around. I was dead in the water in the middle of the road. I left the dead keyfob on the console and went to retrieve my phone to call the dealership service department and the vehicle locked itself with the key fob inside. Onstar tried 4 times to unlock the vehicle without success or recognition of the signal from onstar. GM sent emergency service 3 hours later and they had to break into the car to open it. In order to unhook the car I had to drag a 14' limb out of the woods and block up the back wheels and ease the bus back about 1" to take pressure off the towing system. I cleared the bus out of the road but the vehicle sat in the middle of the road for 3 hours until we unlocked it. This is dangerous and could have been deadly to a pet or baby locked in the car during the heat of the day. This is a GM design issue and they refuse to accept responsibility!

The car fails to lock or disable the extra key (key fob), making it susceptible to theft and joyriding, when 1) passive locking is on, 2) the extra key fob is in the car and 3) a door is opened and closed after the vehicle has previously passively locked. This has been reported to several Chevrolet dealerships, Chevrolet customer care and elevated to Chevrolet engineering in at least two cases. Not only does the owners manual state that passive locking works with only one rke transmitter (key fob) removed, it makes logical sense that it would be designed that way. For example, you take your wife out for dinner. She leaves her purse in the car, with the second key in it, you would still want the car to passively lock if you had that function on and you walked away from the car. Following are the details of what happens when passive locking is turned on and what the possible fatal consequences might be: 1) after the car has been driven, the passive locking system functions properly and locks the car with both key fobs removed or with one fob in the car. 2) with both fobs removed, someone with a key fob can approach the car and open and close the door any number of times and each time they walk away, the car will automatically (passively) lock. 3) if only one key fob is removed, someone with the external fob can approach and open the car but the car will not automatically lock when the doors are closed. Additionally, the key fob inside the car remains active and allows anyone to enter the car, because it is now unlocked, start and drive it away. 4) the unfortunate but possible fatal consequences of having the car unlocked and drivable is that it could be stolen and involved in a fatal accident. Possible scenarios of how this could happen are numerous. GM should acknowledge this serious malfunction, address it and fix it before someone is hurt or killed.

The contact owns a 2015 Chevrolet Tahoe. While driving approximately 15 mph, the vehicle stalled without warning. The vehicle was restarted. The dealer diagnosed that the ground connection needed to be replaced. The vehicle was repaired, but the failure recurred. The manufacturer was notified of the failure and stated that the VIN was not included in NHTSA campaign number: 14V614000 (electrical system). The failure mileage was 7,400.

Upon purchase of a new 2015 Tahoe I observed the possibility of a problem with the forward collision alert system (fca). I reported this to the service manager at Chevrolet. On 9 April 2015 the service manager, assistant service manager, master technician, and I took the vehicle for a test drive. While driving the vehicle at moderate highway speeds I demonstrated the various phases and operation of vehicle detection. The fca has plenty of sensitivity and detects vehicles in excess of the specified distance in the owner's manual which is not an issue. At a moderate closing rate between vehicles the instrument cluster icon changes from green to amber-orange which appears nominal. However, the red alarm heads-up windshield display, rapid high-pitched beeps and red icon are never activated until a closing distance about ~3 feet before a collision. There is virtually zero reaction time for a driver to brake the vehicle at less than one car length before going to red. In addition, the system is supposed to disengage the adaptive cruise control (acc). Considering time, rate, and distance this is ineffective as the mass and kinetic energy also needs to fully disengage before a potential collision. Because of the danger of creating a traffic incident the vehicle was not tested to the level of a full collision. I was informed by the service manager that there are no service bulletins, adjustments, or software patches that may correct this deficiency by the dealer. GM stated that the system works as designed and delivered. The GM forward collision alarm (fca) delivered product appears to have a design deficiency and is an operational safety hazard waiting to happen. If the fca does not function properly then why introduce it to a consumer regardless of GM owner manual warnings about trusting alert systems.

January 15, 2015 not even two weeks after purchasing my vehicle I got in it after work and noticed I couldn't manage the climate controllers (heating/air conditioning/speed/air flow) nothing in the front or back. I immediately called the dealership and sent in a picture. All the knobs and controllers for just the climate were dark, no lighting as if the vehicle was off. I drove it home and since it was so cold out it was thought maybe it just needed to warm up more. I drove 45 minutes home and the climate controllers never turned on again until the next morning. Took it to the dealership because I was also having other issues and they stated they couldn't find anything wrong. Everything has been fine with the climate controllers from that point on until this weekend. On March 21, 2015 I drove to pick up breakfast, everything was fine. An hour later after we piled in the vehicle and were driving I went to kick the air on as it was getting warm and noticed the controllers were not responding again. I pulled over into a parking lot and recorded my actions so the dealership can't say they need to "see it." I turned the vehicle off, tried turning the lights on and off, remote starting, everything but disconnecting the battery. Nothing. The rest of the day while we bounced from store to store with had no air. March 22nd, it was back on as normal. Today March 23rd after work it was not operational again. Something needs to be done, the last post I had on this site was when I had a 2014 GMC acadia and my son over heated from a very similar situation. This is beyond ridiculous that I have yet another GM made vehicle and there is a major issue with a brand new vehicle. GM needs to be held responsible, not having heat or air conditioning in a family vehicle is extremely dangerous for anyone who depends on travel with that vehicle.

- Fayetteville, NC, USA

I bought the car in May 2014. I took it to the dealer in August 2014 per GM recall number 14126 on August 22, 2014. The recall was to reprogram the instrument cluster, even though I had not experienced any problems with the cluster. After the recall work was done, though, the screen on the dash panel operated in a different and dangerous manner. Prior to the recall, I kept the screen on the digital speedometer, for obvious reasons. Prior to the recall, when I would place or receive a call using the bluetooth connection, the screen would switch to a phone screen, but when the call ended, the screen immediately returned to the prior screen, showing the speedometer. Ever since that recall reprogramming, however, at the end of the call, the screen stay blank except for the word "phone", so I have to play around with all of the setting options (buttons on the steering wheel) until I find the digital speedometer again. This is a distraction to my driving, and is a clear error in the reprogramming by GM (of what possible use can a blank phone screen be?). after I complained to the dealer, the dealer gave me a copy of GM bulletin#pit5285 on this very issue, dated May 6, 2014 (before I bought the car, and clearly not implemented on the car), saying that this is a "normal operating characteristic" of the car. That is a blatant falsehood, because I drove it for 3 months before the reprogramming, and "normal" was an immediate return to the prior screen, which in my case was the digital speedometer. I have tried appeals through GM, and they refuse to address this issue further. GM has created a dangerous distraction, and is ignoring the problem. It is an easy one to fix; all they have to do is to reverse their blunder from the earlier recall.

The new 2015 Tahoe have a push button ignition. I pushed off the ignition with the car in drive (forgot to put in park), exited the vehicle and realized the car was rolling down the hill. I quickly jumped in and applied the brakes to stop the car. I was surprised that even though the car is in drive when the car's ignition is turned off, the transmission disengages and the car is in neutral! this is a big hazard. There should either be a fail safe and not allow the car to turn off in drive or automatically place the car in park when the ignition switch is pressed. (this is what happens on a recent model Mercedes.)
