2023 Chevrolet Tahoe driver assistance problems

Filed Aug 28, 2026 · Driver assistance, Engine · FL

A couple weeks ago, the truck suddenly started running rough and the front collision avoidance system failure message displayed. Immediately took it to the dealership. Computer read out showed #7 fuel injector failed. Repaired and was fine. Yesterday, 8/27/26, same thing happened again. Immediately went to the dealership. Now #4 fuel injector failed. Service manager just called and states that Chevrolet does not have that injector and on backorder with no date of expected delivery. No other Chevy dealer has #4 fuel injectors either. Tells me that there is an overwhelming demand for fuel injectors that indicates a defect. Meanwhile, the truck is out of service and GM is not addressing the issue to replace all the defective injectors.

The car has cut off three time while at stoplights. I can get it restarted but the dealership cannot duplicate it even though there are codes in the system. Also the automatic braking will randomly stop when it shouldn’t and it is a hard braking.

To the federal safety agency, I am reporting a serious safety defect in my 2023 Chevrolet Tahoe purchased from Criswell Chevrolet (Gaithersburg, MD). Defects include a documented brake system failure while driving and repeated electrical/shift faults preventing shifting out of Park. The issue is ongoing even after the dealer/manufacturer stated it was fixed. Key events: Feb 3, ~12:45 pm: While traveling ~35–39 mph on a five‑lane road, brakes failed. I slowed by coasting uphill and using maximum pedal force to ~5–7 mph before stopping. I have video of the incident and two other times this has happened with pictures as the car was in park. Three prior start-up incidents: All dash lights illuminated (including brake failure and Forward Collison System Unavailable); vehicle stuck in Park. First required towing; dealer could not replicate despite reported stored codes. Subsequent event stranded my family. I have notified Chevrolet and the dealer; their offer does not address safety or recurrence. Please record this complaint, assess broader risk, and advise on related recalls/investigations. If there is a path forward to ensure the safety of my family, please respond with that guidance. My phone number is [XXX] .

The following notifications showed up on my dashboard as my breaks failed me! I was going down a hill and hit the breaks and they would not work, I could NOT stop the car! - service break pads - forward collision system unavailable - break system failure - service traction control - service esc - check engine light on This is the SECOND time this has happened in 4 weeks. We just got it back from getting it “fixed” one month ago. One of the scariest experiences, losing breaks!

While Driving to my appointments via the freeway, all of a sudden the vehicle slowed down, I noticed most of the warning lights were on including the check engine light that was blinking. I Happened to be near a GMC dealership which previously did repair work on my vehicle and left it with their service center for a diagnostic inspection. A week later my service advisor contacted me with their Vehicle condition report that my vehicle had camshaft and internal engine group issues. He quoted repairs but recommended replacing the engine. Repair or engine replacement $21,296.51. Six months before this issue I had the same issue the warning lights and it resorted in replacing the brake control cylinder. Once repaired no issues/messages or symptoms with my vehicle until this current engine problem/replacement.

On 12/3/2025, I moved my car in the driveway at 11:15am EST without any issue. At 6pm EST, myself and 2 young daughters got into the car to head out an hour away. As I went to drive away, I stepped on the brake and the car did not immediately stop…the brakes failed and came to a rolling stop. At that moment all types of warning and lights lit up the dashboard. I placed the car in park exactly where it was in the driveway and left it. I also tried to select the Ebrake and it would not engage. I called the dealer first thing the next morning as that had been closed at the time it happened. I was told to bring it in and not to drive it so nobody in my car or else would be at risk. The car was towed at my expense to the dealer. When I got in touch with the dealer that afternoon to get a status. They advised the believe the BCM needed to be updated because it seem to not be communicating properly but wanted to keep it over night to retest it before they sent me home with it. Going to point out several things…thankfully I had not left my house, as I live on a mountain and should that have happened while descending it could have been catastrophic. No warning or anything that the brakes would fail! According to records it shows the did a recall update back in Feb 2025 regarding the BCM- however, how are we sure it truly was fixed or was defective. GM/Chevy needs to take accountability for this defect and safety hazard that could result in death. In reading forums, I am not the only one this has happened to

On multiple occasions my vehicle brakes with no warning. So much so I can hear the tires screech ever time. I brought to a dealership and they told me they can’t find the issue and no fault codes. This is understandable due to the fact that it doesn’t always happen. It’ll go so times a full day without happening. It mostly happens on the highway but happened today (24-July-2025) around 17:30. So needless to say this is a huge issue especially seeing I have three small children. Thank you so much for your time in this matter and I hope this finds you well.

First the front collision warning systems kept coming on and off. Then the engine died on the highway and I had to restart. I drove a little further and it died again and would not restart. I had it towed to the dealer and they are telling me the engine has seized and needs to be replaced. I have 40,000 mile and the car is 2 years old. It was very dangerous to have the car die twice while at speed on the highway.

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.
