2021 CHEVROLET TRAVERSE Electrical System Problems

Odometer Fraud. The contact purchased a 2021 Chevrolet Traverse. The contact discovered that there was a mileage discrepancy after the purchase. The vehicle was a private sale. At the time of purchase, the mileage was 49,000. It was later discovered, after checking the Carfax report, that the mileage was 75,000.

Mileage: 75,000

Received a "Service Battery Charging System" dash warning message driving down the highway. Made it home and changed the battery but the issue persists and I can't drive the car. Reading online many complaints/problems with alternator and electrical premature failures. Car is a little more than 4 years old and has only 23,600 miles. Getting the car to the Chevy dealer tomorrow to diagnose problem and fix. If car were to stall out at highway speeds it could be very dangerous. This problem should receive further investigation by NHTSA. Shouldn't have electrical failures on cars with 23,000 miles.

Radio went blank unable to access screen. Not sure reason. Upon start up couldn’t access any parts of radio. Couldn’t reset and issue still current as of today.

MY ALTERNATOR WENT OUT AT 40K MILES IT WAS REPLACED AND NOW WENT OUT AGAIN AT 75K. I HAVE GONE THRU 7 BATTERIES SINCE I BOUGHT THE CAR BRAND NEW. THE CAR DIED ON ME IN THE MIDDLE OF IN INTERSECTION AFTER GETTING THE NEW ALTERNATOR AND BATTERY REPLACED 3 WEEKS AGO. THIS IS A HUGE SAFETY ISSUE!!!!!

The contact owns a 2021 Chevrolet Traverse. The contact stated that while driving at 20 MPH, the vehicle inadvertently lost motive power and stalled. The contact lost power steering functionality and was unable to move over to the side of the road. No warning lights were illuminated. The vehicle was towed to an independent mechanic, and the alternator was replaced. The contact stated that it was the second time that the alternator was replaced. The contact stated that on a separate occasion, the vehicle failed to start. The vehicle was jump-started, and the vehicle was taken to an independent mechanic who replaced the battery. Most recently, the vehicle failed to start, and the contact was unable to open the doors. The vehicle was towed to an independent mechanic who replaced the battery again. The manufacturer was notified of the failure and offered assistance. The failure mileage was approximately 20,000.

Mileage: 20,000

On [XXX], Onstar did an Auto Unlock on my car. After the car was opened, the entire radio panel didn’t work. On June 13th, Bob Johnson replaced the Onstar telecommunications module. Only the radio worked with the screen black for a couple of minutes. Then it stopped working. They stated that they ordered the part, but every time I call, they haven’t.

Vehicle: 2021 Chevrolet Traverse Problem: Persistent “Shift to Park” message when vehicle is in Park I own a 2021 Chevy Traverse and have experienced repeated incidents where the dashboard displays “Shift to Park” even though the gear shifter is securely in the Park position. This prevents me from turning the vehicle off and has caused battery drain and confusion about whether the car is fully secured. This issue is clearly known by GM, as evidenced by a Technical Service Bulletin (TSB #19-NA-206 and others). It affects multiple model years and has prompted a class action lawsuit. Despite the widespread nature of this defect, GM has not issued a recall. I believe this issue presents a safety concern, particularly for drivers unaware that the car may not fully power down, and due to the potential for battery drain and immobilization. I urge NHTSA to investigate whether a recall is warranted

The vehicle does not recognize when the vehicle is shifted to park. It states “shift to park” when the vehicle is already shifted to park. When this happens and the push to start button is pressed to shut the vehicle off, the vehicle will not shut off which becomes a major issue as the car continues to run and the vehicle’s battery will die since the vehicle will not fully shut off. This is a safety hazard because the vehicle can end up with a dead battery when this happens. I’ve looked this issue up online and it is a common issue that Chevy has failed to address.

My car came up with an alert message when I started the vehicle, "Service Battery Charging System Vehicle May Stall". I assumed using my remote start had somehow drained my battery or that the cold weather (30 degrees) was affecting my battery. I began driving hoping the battery would charge once running. Another alert came up, "Battery Saver Active". The alerts repeated again. In less than 10 miles from where I first started, I made it to a Les Schwab where I asked them to check my battery. The guy ran out and said my battery had more juice not running. They told me to take it to service repair shop close by. I began driving to the nearest shop and my car jerked/stopped/died, the steering was locked up and I lost complete control of the vehicle but luckily I was not far out of the Les Schwab parking lot and was able to coast into another parking area. I had to have my car towed to the repair shop where they told me it would cost $1,600 to replace the alternator, I luckily have a Platinum Extended Warranty and it appears to be covered. I am so thankful that I was not on a highway at the time and that I took the alert seriously and responded immediately. My 14 year old was in the car with me and it really scared her that the car jerked and stopped. The amount of time I had from receiving the alert to a dead battery was very short. This should not happen and I'm so glad that I was driving versus an up and coming driver (turns 15 next week) that would not have known what to do. I've done my research and this issue has been mentioned in several chats regarding owners experiences for Traverses' around the 30,000 mile mark, my car is at 40,000 miles and was serviced at 30,000. I'm honestly not sure I can ever trust my vehicle after this experience. Others have said that they fixed the issue only to have it happen again.

The battery wasn't being charged which caused some problems. However, it was the alternator that was bad. Since the battery wasn't being charged and the alternator was failing, there were problems with steering and engine power which almost caused a collision at highway speeds.

3 times in 5 days, 2021Traverse completely shut off. 2 of those times were in a busy intersection. I couldn’t even turn my flashers on and had to manually unlock my door to get out. Fortunately the third time was in my driveway. I called AAA to tow it to dealer. This is a severe safety issue and hopefully will be covered under my warranty and the extended bumper to bumper warranty.

When leaving work last night, a warning appeared saying 'Service Charging System Vehicle May Stall' and shortly after another showed "Battery Saver Active" so I went to my local auto parts store and had the battery replaced for $300. The gentleman also ran a test on the alternator and it came back with a failure on the voltage regulator but all others were good. I drove home hoping drive cycles would clear it out. I drove to work this morning getting the same errors and voltage not going above 12.0, dipping all the way to 11.5. So now, I have to replace the alternator, praying it does not shut off on the highway and I get hit and killed. I have seen numerus incidents online of the exact same issue. I bought this car brand new (my 1st ever) in 2021, I only have 25,000 miles on it, she is garage kept and very well taken care of, this should not be happening on a practically new car. Please do something before more get injured or even killed.

I bought my 2021 Chevy Traverse brand new. Now it has about 44,000 miles on it and is just under 2 months of purchase date. I noticed that my battery light turned on yesterday while I was driving. Within seconds my vehicle stalled out and I was just coasting along in traffic, unable to restart my car. I was able to coast to the side of the freeway and jump my car. After doing so it started again so I proceeded to drive away. After about 4 more minutes my vehicle shut off again as I was driving in traffic. I was unable to get the car started again and was just a sitting duck in heavy traffic. I had the vehicle towed and a new battery was put in. My vehicle starts but the new battery is already loosing voltage. After a diagnostic test was done by the mechanics at the auto shop it looks like the alternator needs to be replaced. This is not only unheard of that such a new vehicle would already need a brand new alternator, but it was also a huge safety risk with how it all happened so quickly with VERY minimal warning and the vehicle completely shut off while I was driving in heavy traffic. So many people could have been harmed due to this malfunction.

Warning on dash to check charging system. Driving on highway, all lights on dash started lighting up and going crazy and then everything on dash completely shut off while I was driving. Car eventually stalled. Car has less than 40k miles and only 3 years old. Brought it to dealership and they said it needs new alternator and battery.

Battery charger notice came on and on way to go have it checked the car stalled in the middle of a busy road and i had problems turning the steering wheel few seconds later the engine stopped running completely.

On [XXX] my 2021 Traverse with 46K miles, purchased new from Atlantic Chevrolet, Bay Shore, NY, broke down on the road, dead battery, and alternator. I could not successfully jump the car to get it running. I had no use of steering, nor could I shift the vehicle into neutral to move to the roadside. Prior to towing the vehicle, based on my car insurance, Atlantic Chevy was outside of my towing area and would have cost me $500.00 out-of-pocket to tow. I called customer service and a female employee told me that the battery issue would not be covered. I had the car towed to my local mechanic, upon inspection they determined that the alternator failed, and needed to be replaced. I called Atlantic Chevy again and explained the issue to the same representative, she told me that that would not be covered based on my expired warranty. To be sure, I proceeded to call GM corporate. I spent an hour on the phone with a representative who ultimately told me that it would not be covered. I had no option but to have the repair done by my local mechanic. They purchased the alternator from Atlantic Chevy to ensure that they were installing certified parts for which I paid out of pocket. It goes without saying, that an alternator should not fail with such low mileage and after researching, I have found that there are identical complaints for the same year, make and model car. I contacted GM corporate to file a formal complaint, and ask for compensation. I dealt with a very competent person who exhausted all of the options within her corporate structure, but to no avail, GM refused to take responsibility, and would provide no resolution.

The alternator is placed right under the fill cap for engine oil. So if and when an auto repair shop or owner spills oil out of a funnel or anything else this oil will leak and the first spot it drips onto is the alternator. With all the other plastic under the hood there should be some kind of shield bracket or sloped plastic to get in the way of all the other maintenance under the hood. So precede with caution and avoid the unnecessary cost of an alternator change.

The contact owns a 2021 Chevrolet Traverse. The contact stated that while operating the vehicle on several occasions, the vehicle shut off and the steering wheel became difficult to turn. Additionally, the interior and exterior lights became inoperable. The vehicle was taken to the local dealer who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The contact was concerned that the failure was caused by the vehicle being hacked by a local terrorist network. The failure mileage was unknown.

Display Instrument Center on the instrument cluster goes out for a couple of drive cycles and comes back on. I took it in to the dealer at the end of March and had the vehicle updated. There's a history with this issue with the Traverses and the Cadillac XT6. I don't know if it's a glitch when these parts were produced for GM or not but it needs to be investigated

I have a 2021 Chevy Traverse LT. The stereo touch screen keeps completely freezing. We've brought it to the dealer who told us it was working fine. Its frozen twice. Once we had to pull the fuse out to reset it for it to work. Vehicle has a rattle at startup and suspension squeaks. Captain seats almost seem loose, they rattle at times. The brakes are horrible, they squeak all the time. Pads are not worn, but it appears from my mechanical knowledge that the pads are slightly oversized to the rotor or not set on straight and they're rubbing the unmachined part of the rotor which could contribute to the brake issue. Dealers have claimed before its just ceramic rub, however; I have done tons of brake jobs and ALWAYS use ceramics. NEVER had a problem with that. Vehicles need a MAJOR recall for all these systems as they can all be a major safety concern. Brakes not set on right or pads to big can cause the pads to break off causing loss of braking power and an accident. Seats not tightened properly can cause death or serious injury to passengers in an accident. Failing suspension can cause loss of control of the vehicle and an accident, freezing touch screen can cause an accident if the driver is using the Nav system and it stops.
