2024 Chevrolet Traverse Electrical Problems

I am reporting a serious safety incident involving my 2024 Chevrolet Traverse RS AWD, with approximately 34,378 miles. On or about [XXX], while the vehicle was being driven near Sarasota Florida at approximately 25 mph, it suddenly lost propulsion and all electrical power. The instrument panel, displays and vehicle electrical systems went completely dark. The vehicle was completely dead and would not restart. Police subsequently jump-started it, but the vehicle’s systems did not initially operate normally. This vehicle previously experienced another complete electrical-power failure while parked overnight, and the dealership has a record of that incident. Following the in-motion shutdown, the dealership performed a complete software flash using USB and stated that a software problem may have caused a parasitic battery draw. I understand how a parasitic draw could discharge the battery while the vehicle is parked. However, I have not received an adequate explanation of why the vehicle lost all electrical power while the engine was running and the charging system should have been supplying power. I am requesting that General Motors open a formal product-safety case, review the dealership’s diagnostic and programming records, determine the complete cause of the in-motion shutdown, and provide written confirmation of the tests and repairs performed. Please provide me with the GM case number and escalate the matter for appropriate technical or field review.

Vehicle: 2024 Chevrolet Traverse Z71 Mileage at first incident: 25,821 My 2024 Chevrolet Traverse Z71 experienced multiple safety‑critical electrical and ADAS failures. The vehicle had a Reduced Acceleration / limp‑mode event, accompanied by a strong antifreeze odor inside and outside the vehicle. Dealer diagnostics on 06/29/2026 and 07/16/2026 confirmed several trouble codes affecting the engine, braking system, and collision‑avoidance systems. The following diagnostic trouble codes were recorded: P3705 – Engine Coolant Pump Control Circuit Low (engine cooling fault) C0609 – Park Brake Actuator / Switch Signal Fault (brake system logic fault)-Active 6.29.26 10:12:43AM U160A – Lost Communication With Serial Data Gateway Module (CAN‑bus gateway failure)-Active 6.29.26 10:12:43AM U197A – Lost Communication With Front Radar Sensor Module (forward collision warning / AEB disabled)-Active 6.29.26 10:12:43AM These faults caused loss of radar‑based safety features, including Forward Collision Warning, Automatic Emergency Braking, and Adaptive Cruise Control. The vehicle displayed warnings and temporarily disabled ADAS functions. The Reduced Acceleration event created a hazardous situation in traffic. The dealer attributed the incident to “low coolant,” but the diagnostic codes clearly show electrical and communication failures across multiple safety‑critical modules. The antifreeze odor continues, suggesting a possible coolant leak or unresolved cooling system issue. The vehicle has been inspected by GM technicians, and the codes were documented on both visits but they say car is fine. The safety systems affected include brakes, engine cooling, electrical CAN‑bus communication, and collision‑avoidance radar modules. I am requesting NHTSA to record this complaint and evaluate whether these failures represent a broader safety defect in the 2024 Chevrolet Traverse Z71.

This has happened two times. Driving down the road between 35-55mph. "Speed limited drive with care" no CEL. Took to dealer, advised with a CEL or no codes nothing they could do for it. Multiple nights I get home and the fan stays running after engine shutdown. Engine overheat within 10 min of drive time. OIL SMELLS LIKE FUEL. This time engine throttles back and nearly caused accident with not being able to merge.

I am filing this complaint regarding a persistent and unresolved defect with my 2024 Chevrolet Traverse, VIN: [XXX] . The first occurrence of this issue was in June 2025. Since then, the vehicle has repeatedly experienced a “Check Engine” warning, engine misfires (cylinder misfire), loss of power while driving, and severe engine shaking. These symptoms make the vehicle unsafe to operate. The vehicle has been taken to an authorized Chevrolet dealership approximately 20 times for the same ongoing issue. Despite multiple repair attempts, the problem has never been permanently resolved. In total, the vehicle has spent about three months out of service at the dealership. As of January 14, 2026, after the vehicle has been at the dealership for over two weeks, I was informed that the dealer is unable to repair the vehicle. They have escalated the case to the manufacturer, General Motors, because they cannot identify a permanent solution. The current mileage of the vehicle is approximately 41,700 miles. This ongoing defect makes the vehicle unreliable and unsafe for normal use. The repeated failures to repair suggest a potential manufacturing or design defect rather than an isolated incident. I respectfully request that the National Highway Traffic Safety Administration review this matter and determine whether an investigation or further action is warranted.

I am experiencing a recurring battery/charging system detection warning with my vehicle that has not been resolved despite multiple service visits. The warning continues to reappear after the vehicle is returned to me, indicating the issue has not been properly diagnosed or repaired. My vehicle has been in the shop approximately 5 times for this same issue. Each time, I am told the problem is resolved or that they cannot replicate the issue, yet the warning returns shortly afterward. To date, no permanent fix has been provided, and the underlying problem has not been remedied. I have made repeated attempts to work with GM and the dealership, but meaningful assistance or escalation has not occurred. This ongoing electrical issue raises concerns about the reliability and safety of the vehicle, as well as GM’s failure to correct a known, documented problem. I am requesting appropriate escalation and resolution, including further diagnostic intervention by a regional service manager or field engineer, or consideration of alternative remedies if the issue cannot be permanently repaired.

On July 31st, while backing up on a clear road in rain the brakes locked suddenly. The brakes applied & a message saying Emergency Parking brake engaged. Must be manually released. This happened twice in a 30 second period before there was enough room for me to pull forward out of the spot. I called the dealership on August 1st to see if this was a known issue and they said no. Brought the car in on August 2nd. They scanned for errors & found a message Lost Communication with Parking Assist Control Module with 9 other error message. They said this was not a known problem and to them it appeared to fix itself but would let me know if there was any way to fix. Car has just been in for regular multi point inspection on July 24th. On August 20th went to get in the car but none of the key fobs would open it. Called two dealerships but neither could come up with answer. Chevy Roadside was called & came to get into the car and ended up jumping it. At that time the battery was tested and it appeared fine. It was recommended to run it for a half hour. I ended up driving it for an hour with no extras on. On August 25th the next day I went to drive it the battery of this 1 year old car was dead. Called the two dealerships to see what could be done & was told to bring it in. Called Chevy Roadside Assistance who dispatched someone to open the car and jump the battery. This person found the battery was not holding a charge & said nothing when I said I was driving it to the dealership. Got 3 houses away & a message that the Brakes have failed. Press hard to brake popped up. In addition the steering locked up. I missed hitting a lady with a kid in a stroller by 6 ft but managed to get it to the curve & with 3 pushes into park. It was towed to the dealership. When it arrived at the dealership the brakes locked up so it would not back up off the flatbed. It had to be forced off. Dealer blames poor battery but can't explain July 31st or why battery readouts say okay.

Bought 2024 Traverse end of June 2024 from show room at Flow Cheverolet in Salem, NC. In Sept 2024, took it in for glitchy screen/radio black and colorful lines displayed, squeeky brakes, and dashboard rattling when hitting 60+ miles. Chevy fixed the screen but said they could not do anything about brakes or the rattling of the dashboard. March 2025- brakes still squeeked and brake failure message came on, took in they had to order and replace brake sensore. I informed them that when backing up the automatic brakes come on stopping the car when no vehicles are coming would take 3 to 4 tries to back out from driveway but this problem was not addressed. July 2025- check engine came on, was told cylinders 2 injection pulse offset exceeded minimum learning limit suppositely just needed some STP August 2025- check engine came on again took in to Cheverlote they said they needed to order and replace Fuel injection pump because it was faulty, but that day recieved a text from the car saying battery was dieing while at Cheverolet service department. Car has been at the service department for over a week and they still can't figure out why its not holding charge. Battery has been replace twice while at their shop. Most important issue the millage is stating it has 25,400miles but we know for sure we have not traveled or driven but maybe half that millage in the pass year and chevy's mechanic is stating there is no way for them to confirm that. Too many issues for a car bought brand new only a year ago and because of the faulty odameter we only have about 10,000 miles left of warranty.

I was taking my daughter to school; we were about 5 minutes from our home. I came up to a red light and stopped no problem, it turned green and as I proceeded through the intersection to the next red light to make my left-hand turn to get on the freeway, my rearview mirror camara flickered and that was my first indication that something was wrong. After that the ac started turning on and off and my dash lights all started lighting up. Fortunately, I was only going about 15-20 mph, so I was able to get the car to stop without incident. I had a few seconds to decide what to do, I determined that making a U-turn when the light turned green was the safest option, that's when I realized I had no power steering. I was able to safely get the car back to my driveway and called a tow truck. The car is now at JK Chevrolet Nederland, Tx and now waiting to hear diagnostic.

Incident 1 - Dashboard Electrical Failure Date: June 11, 2025 Mileage: approx. 10,000 Problem: Multiple dashboard error lights activated simultaneously, including false "dead battery" warnings despite the vehicle starting normally. The vehicle could not be shifted into gear and could not be shut off through normal ignition procedures, requiring manual battery disconnection to resolve. Incident 2 - Power Steering System Failure Date: June 12-13, 2025 Problem: Complete power steering failure. Temporary resolution achieved by battery disconnection and reconnection, indicating systemic electrical issues. Incident 3 - CAN Bus Communication System Failure Date: July 6 and 9, 2025 Problem: Check engine light with diagnostic code U0073, indicating Controller Area Network (CAN) bus communication failure - a critical vehicle system malfunction. On July 11, 2025 my wife had the oil changed and the mechanic assured her, “It’s just a glitch ma'am, like a computer. Just restart the car 2 or 3 times.” Incident 4 - Recurring Power Steering Failure Date: July 12, 2025 Problem: “Service ESC and Power Steering”. Power steering system failed again, demonstrating that previous "fixes" were ineffective and the underlying defect persists.

Purchased vehicle brand new. Six months and 10,000 miles later vehicle giving codes that say key missing / check for key. Then another that says key not found put key in center console left cupholder. When the key not found error or key missing error comes on the vehicle will not start. Thankfully this issue happened when I was local as this could strand the occupants in potentially dangerous situations (heat/cold weather, remote locations, ect.). This also prevents the vehicle from shifting into neutral for towing purposes, therefore forces the tow company to "drag" the vehicle onto the flatbed and "shake" the vehicle off the flatbed as the wheels are locked. This happened on and off, sometimes once a day and sometimes can not start car at all that day. The vehicle has been at the dealership for TWO MONTHS now as they have not be able to fix the issue. The dealership has been able to reproduce the problem and has confirmed it is a problem. GM has been contacted about the issue as well. This is the exact same issue as NHTSA ID Number: 11645578

Bought it back in July. Had it taken back that first month for the 3rd row headrest issue. Then the check engine light kept coming on, 1st time they said it was a cylinder misfire code, they rest it and said try getting gas from a different station.. light came on 3 more times, but by the time we took it in, they “can’t replicate the issues”. Then the tire sensors went out, took it in and they had to order a new sensor. Then this past weekend we lost total power steering while driving 40+mph. Then it happened again the next day, but this time we lost complete control, entire car shut down, screens off, no breaks, no power steering, no nothing. We let it coast to a stop then put it in park. Took it to the dealership the following morning. They read a bunch of codes. Said they’d call with an update later that day. Now it’s been 3 days, and they can’t replicate the issues and are at a loss as to why it happened or how to fix it to prevent it from happening again. Said it might be something to do with central computer system.

Vehicle keeps giving codes not even a month after purchased that say key missing check for key. Then another that says key not found put key in center console left cupholder. This has happened multiple times already and the dealership supposedly said the first time it was a programming issue and needed to be reprogramed. They did that and the vehicle did the same thing. Errors for low battery service battery pop up. Along with service keyless start system. When the key not found error or key missing error comes on the vehicle does not start. I have been stranded when this happens because it does not recognize the key therefore the truck wont start at all and has to be towed. The codes usually pop up first then the vehicle does not start. I took it in because I started getting the codes again and again after the vehicle was releasd to me it again did the same. Happened a 3rd time and after several attempts of starting the truck after getting stranded again the 4th time it happened was at the actual dealership when i prayed it would start to get me there. The service write disconnected the batter to clear the codes so he can start it to move the vehicle because it was in his way. Now im being asked by the dealership that the engineers want to know what I am plugging into the vehicle to make it interfere w the vehicle not starting. I filed a claim w gm to have the vehicle swapped out but the dealership has not returned their emails. There was damage like if someone backed into me that thr dealership said knocked off sensors and was causing it to go out of whack. I paid to have everythjng repaired which was told would resolve the issue and a few days after repaired happened again. I was told it was failing all tests. But because the bay the vehicle was on was needed they reset the codes again and now the engineer cannot get the truck to fail.

When turning using signal upon straightening back out the lane change signal activates for the opposite direction I actually turned. Seems to happen on sharper turns than wide turns. I believe this is a safety issue and it looks to others that I may be switching lanes or turning again.
