2024 Chevrolet Tahoe

Engine failure. Tahoe lost all power on the interstate going 70mph. Was able to get it to the side of the road and restart it. Engine started knocking and became undriveable.

I own a 2024 Chevrolet Tahoe RST and have experienced recurring electronic/electrical problems despite multiple dealership visits. The vehicle repeatedly displays “Open Then Close” window messages for the passenger or driver window even though the windows function normally. While driving, the infotainment screen has repeatedly gone black, causing the audio/music and audible turn-signal indicator/chime to stop working. On one occasion while stopped at a red light with the vehicle running, the infotainment screen and entire instrument cluster went blank and rebooted. The Chevrolet logo remained displayed during the restart, and the audio and turn-signal chime stopped working. The dealership has been unable to duplicate the issue but has performed software updates. The problems continue. Most recently, the vehicle displayed “Service Transmission Now — Unable to Shift Soon.” The warning disappeared. The dealership then stated the 12-volt battery was low and needed replacement before accurate diagnostics could be performed. I replaced the battery, and afterward the check-engine light came on. A complete diagnostic has not yet been performed because my appointment was rescheduled. I am concerned these recurring electrical/electronic issues, transmission warning, and check-engine light may indicate an underlying safety-related defect. I am requesting that GM formally document and investigate these concerns.

Tahoe was purchased new in November 2024. Vehicle currently has around 37,000 miles and has been regularly serviced by GM dealers. On Sept. 9, 2026, was driving in moderate rain and wipers just stopped working. After stopping at a nearby gas station for about 5 minutes or so, the wipers again began working. I am currently having intermittent wiper failure. Sometimes they are really slow even on the “high” setting. Something is wrong with them and fuse was checked and is good. This creates a very dangerous situation that could cause serious injury or death if the wipers (on a new 80,000 vehicle) suddenly stop while driving in rain. This is a serious danger to public safety and GM needs to issue a recall for a fix. Research online indicates GM is aware of the issue under TSB PIE0774, but is not offering resolution to vehicle owners. As well, online research shows a class action lawsuit is pending. The NHTSA needs to take prompt action and direct GM to correct the matter for public safety.

I experienced the issue being investigated with Investigation: EA26005 I lost engine power while driving my 2024 Chevy Tahoe. GM is now conducting a full engine replacement with another L87 engine.

Upon getting into vehicle , a pooling of fluid was in the all weather mats.. with a visible leak line from top of mat to the pooling area on driver side. It did not dry as water would and it was a slightly oily feeelign and left an oily residue. Several day later after the vehicle sat over the weekend, more pooling was noticed with same leak line at top of mat to area where pooled. Upon further investigation and with picture documentation a dead on line for line leak from the brake down pedal shaft onto the all weather mat . and once at the mechanics it was confirmed to be a leak of the master cylinder. Many recalls have been done on other models as well. My warning light or module also has not alerted to the loss of brake fluid.

Brake System Failure 62 MPH Top Speed Service ESC Service Brake Trailer System These warnings appeared on 04/30 and my brakes became extremely hard to use to stop my vehicle. I had my two young children in the car, I was able to go up hill and shift it into park after driving 15 minutes basically with no brakes. It was towed to Hendrick Chevrolet, where they replaced the master cylinder. On May 5th I was driving the car and the service brake assist light came on with the message. I then had it towed to Hendrick where it stayed until July 28th. The dealership stated that it was an external leak in the master cylinder. Now for the 3rd time the brakes are making a squealing noise and the service brake assist light is on again. I do not feel safe in this vehicle.

Engine locked up from crankshaft bearing failure, mega fuse blown My wife and I were driving 70mph on a highway when I lost the throttle and other power. I pulled over to the side the best I could but barely over the white line. It was a dangerous situation for us & tow trucks, the engine was locked up & the flat bed truck couldn't tow vehicle. The 2nd truck was a reaper style truck which was dangerous to setup on the side of highway. The dealership diagnosed and replaced engine to their guidelines. I requested the oil cooling lines & housing be replaced as well to avoid metal debris to enter new engine to avoid recurring engine failure. At first both requests were denied, then another dealer represntive said the oil lines would be replaced but the housing would not be. I even offered to pay for that replacement which was denied. I invested a lot into the vehicle, I was assured the original recall and engine oil change would be sufficient. I also purchased to dealer premium care package to really take care of my vehicle investment.Engine failure was around 29,000 miles. The engine failure happened on a Sunday morning, I didn't receive any loaner car or rental car until Thursday affecting my work transportation. Once the dealer rented me a car, I asked if I needed anything to pick up the car, dealer rep said no. Once at rental car place, I needed a credit card and ID, I was charged $250 for the time I had the rental car. The rental car was not close or comparable to my vehicle, which I still had to make payments while it was broken at the dealership. I really worry about my safety, reliability and travel going forward with this vehicle. I also am very concerned about the vehicle losing value due to known issues. There was no warning signs until the failure, I believe the dash message said 'please press start' or 'press start'. Overall this has been a tough and stressful situation with my expensive vehicle investment. Vehicle unavailable- 7/26-8/17

While driving, my Chevrolet Tahoe suddenly developed a severe, rhythmic bottom-end engine knock, indicating a catastrophic internal mechanical failure. I immediately took the vehicle to an authorized Chevrolet dealership on May 29, 2026, for emergency diagnosis.The dealership technicians officially diagnosed the issue as a severe lower-end engine failure. They deemed the engine unrepairable and determined that a complete long-block engine replacement is required.As of today, July 6, 2026, the vehicle has been sitting at the dealership for over 5 weeks and has yet to be fixed. The prolonged delay and sudden mechanical failure present a severe safety hazard, leaving me without a vehicle due to known GM manufacturing defects currently under NHTSA investigation. This report is being filed to document the failure of the 6.2L engine lower end, the necessity of a full long-block replacement, and the ongoing repair delay.
