2025 CHEVROLET TRAVERSE Electrical System Problems

The contact owns a 2025 Chevrolet Traverse. The contact stated that immediately after purchasing the vehicle, the vehicle experienced several electrical failures, including the On-Star module malfunctioning. The On-Star module was replaced twice. During the failures, the cruise control feature became inoperable, and the computer updates were not received. Additionally, the battery became drained several times, and the vehicle needed to be jump-started. The contact also indicated the shark fin antenna had ejected from the vehicle while driving. The vehicle also abruptly stopped while driving on several occasions, and while driving, there was an abnormal metallic scraping sound coming from the engine compartment. The radiator hose had failed, causing coolant to leak from the vehicle. The hose was replaced, and the vehicle was repaired. The manufacturer was notified of the failures. The failure mileage was 44,000.

Mileage: 44,000

Driving home - what looked like warning indicators on the dashboard, came on. Lost the ability to brake. Had to push the pedal all the way to the floor to get some braking to happen. A message came on the dashboard “Brake Assist failure. Press hard to brake. Speed Limited”. Once we were able to stop. We turned the car off. then turned it back on. We saw a message on the dashboard to “open the drivers door” and then “roll down the drivers window”. We did that and the car seemed to be normal again

Driving home coming up to a traffic light - I turned left onto Rd - After turning lost the brakes. Saw message on dashboard along with many others indicators as well. Saw the same message as the previous time ““Brake Assist failure. Press hard to brake. Speed Limited”.

All connected services do not work. The car cannot receive any updates to software/hardware posing potential safety issues. There was no warning. They all just stopped working. The vehicle was brought to the dealer in the beginning of October 2025 and I still do not have a fix or solution or potential timeline.

Beginning in May 2025, my 2025 Chevrolet Traverse began exhibiting a false “rear liftgate open” condition when the liftgate is fully closed. This defect triggers a continuous audible alarm that occurs before every drive and persists for the entire duration of the drive, stopping only when the vehicle is turned off. As a result of this defect, the rear windshield wiper and washer are disabled, eliminating rear visibility during rain and snow. The vehicle alarm system also cannot be armed, creating a security risk. The continuous alarm causes significant driver distraction, and the loss of rear visibility impairs safe operation of the vehicle, particularly in adverse weather. Minor children are frequent passengers, and the defect has occurred while they were in the vehicle. The vehicle has been presented to an authorized Chevrolet dealership on four separate occasions for the same issue. Multiple repair attempts, including diagnostics, software updates, component replacement, and latch assembly replacement, have failed to correct the defect. Because the alarm cannot be armed, the vehicle was left unsecured and was subsequently broken into, resulting in theft of personal property. General Motors has been notified and declined repurchase, directing me back to repeated diagnostics despite the unresolved safety-related defect. Problem Category: ☑ Electrical System ☑ Visibility / Wipers ☑ Warning Systems ☑ Vehicle Safet

A car approached my blind spot and the blind spot detection did not alert. I tried to change lanes assuming the system was functioning and nearly ran someone off the road. Shortly after this the “service blind spot detection light” came on. Following this failure the vehicle telematics went out rendering the paid on star safety system useless. Parts to remedy the issue on indefinite back order per GM on 12/8/25.

Brake assistance failure. Brakes failed! ESC SERVICE I was able to set it up for inspection Could of caused a accident hurting other people or hurting my family, I use this vehicle to transport my 2 babies Vehicle would not brake properly could have cause serious injuries For my vehicle not yet has not been inspected it was towed, from what I have heard from current Traverse owners they have experienced this same issue with even lower milage No warning lights no indications of failure just happend instant twice

Brake booster failure, master brake cylinder failure

Telematic control module failed. vehicle has 7k miles on it and brand new. Still under bumper to bumper warranty. Dealership diagnosed the emergency services /navigation system failure and ordered the part which is on significant backorder to due to nationwide shortage. No eta for repair. Problem occurred oct 25, 2025. This needs to be a recall. dealership not providing suitable and comparable loaner due to not having 3 row available. stating enterprise does not have one. put me on waiting list for suitable loaner. escalated to gm customer care, gm customer care supervisor, gm executive resolution, dealership supervisor with no immediate solution. Will be filing lemon law case.

The master cylinder and ABS braking system failed, rendering the vehicle inoperable and leaving my family stranded approximately 285 miles from home. This represents a serious safety defect, as the braking system malfunctioned while the vehicle was in operation. The dealership has confirmed the issue, and the vehicle has remained in their possession for over two weeks awaiting parts and repair. During the failure, multiple warning indicators illuminated, including the ABS, Service ESC, and brake system lights. Once the brake system engaged, I was unable to release it or drive the vehicle any further.

Service ESC & Brake Assist lights came on after only 4 months with the vehicle. The vehicle also abruptly slammed on the automatic brakes when backing into a parking spot with no obstacle present prior to the service lights indicating any issues. The vehicle was diagnosed with a failed brake master cylinder nearly two weeks ago, but the part is still on national backorder and will be stuck at the dealership for an undetermined amount of time with no loaners available. There are plenty other accounts of this same issue happening to other newly-bought '25 Traverses, and the N242482170 bulletin related to the '24 model hints at this being a recurring issue. This safety issue on a brand new vehicle without recognition/resolve is unacceptable.

I star failed and I could not use any of my lane assist. All features quit working that were to help me with other cars approaching failed. Radio quit work it working. Battery in car needed to be replaced and car needed to be jumped started. Curse control did not work. Had less than 2000 miles on car. Safety features in car quit working.

Dashboard started showing brake assist and esc needed service. Four lights lit up: brake, abs, traction, and collision

the whole dashboard lit up with break and park indicator lit up in red on dashboard. warning flashed about automatic break system failure and ESC warning

Several alerts came on, including ABS light, SERVICE ESC, SERVICE BRAKE ASSIST, ADAPTIVE CRUISE CONTROL UNAVAILABLE. Blind spot alert stopped working. Dealership reset everything but the issue came back within a few hours. They said it may have something to do with the brake system

Master cylinder went out with only 5400 miles

The contact owns a 2025 Chevrolet Traverse. The contact stated that while driving at approximately 45 MPH through a green light, another vehicle failed to yield at 50 MPH for a red light due to being impaired, causing a collision in which the contact’s vehicle was T-boned. No warning lights were illuminated before the crash. The front and side curtain air bags failed to deploy. The contact reported that no injuries were immediately sustained, and no medical attention was provided at the scene. However, the contact was later transported to a local emergency facility and diagnosed with a back injury. A police report was filed.. The vehicle was towed to an independent mechanic, where it was diagnosed that the air bags, service brakes, and battery of the vehicle had failed and needed to be replaced. The vehicle was not repaired. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure, and a case was opened. The failure mileage was approximately 13,000.

Mileage: 13,000

We purchased this 2025 Chevy Traverse on 6-13-2025. The dash goes dark/blank thus not allowing me to know the speed, amount of gas nor any information on the driving including driver assist measurements. I have taken the car in twice with no satisfaction. I received it back on Friday - 8/22/2025 and within 3 miles the screen was blank again. This makes the vehicle unsafe and dangerous.

I purchased a 2025 Chevy Traverse in April 2025. The car had under 1056 miles on it. I was in another state 325 miles away from home when lights came on in the car. The PARK brake came on, the ABS light came on and a few others. The alert said, Service ESC, and service Brake Assist. What component or system failed or malfunctioned, and is it available for inspection upon request? We did research online and there were 33 other complaints from people with similar complaints. They reported that it was a master cylinder part and the dealers don’t have the part in stock. It could take up to two weeks for the part. How was your safety or the safety of others put at risk? My safety and my husband’s safety were at risk because we had to drive the car home. Our lives were at risk if the brakes failed. We took it to Key Motors a Chevy dealership in S. Burlington, VT. He said they would have to diagnose it themselves and the part could take two weeks or more. We cut our vacation short and could not stay in VT that long. We are elderly and did not have enough medicine, not to mention the cost of hotels. The VT dealer said without the computer, the car defaults to the driver like a 1980’s car. We took our chances and drove it home. Has the problem been reproduced or confirmed by a dealer or independent service center? No, but many people online have complained of the same problem. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? We had it towed to our local dealership, Bob Johnson Chevrolet. They just sent us a bill for $214 for certified multi point vehicle inspection. I still don’t know what problem. Onstar diagnosed it as ABS braking and stability diagnostic code; an issue has been detected in the Antilock Braking System. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No other warnings or symptoms before messages appeared.

Parked the vehicle a Saturday evening went to get into it Sunday morning and the dash was lit up with abs light, service ESC, traction control, check engine light. Called the dealership I bought it from to tell them what was going on, brought it in on a Monday evening to be looked at Thursday. Was called to be informed the master cylinder went bad. Was told by the service manger part would be in to be fixed Wednesday. Wednesday came and gone with no call, finally got a call Thursday evening that the part did not arrive and NOW they have no ETA on the part.

My Traverse prompted me to do an update - I did- and all my cameras stopped working- took to dealership - they tried to do a Manuel update and locked up the whole system- and the USB’s stopped working - 4 weeks later waiting on new system and no answer in site for when parts will be in - contacted GM and they escalated issue - told to be patient - just made my 3rd payment - I want a new car not a traverse - want them to buy back their lemon - after reading all the issues shame on GM for ignoring all these complaints

The transmission system on my 2025 Chevrolet Traverse began showing signs of failure approximately 2–3 months after purchase. Symptoms include erratic shifting, gear hesitation, and sporadic power loss while driving. Although the issue was promptly reported to Chevrolet headquarters, I was unable to bring the vehicle to the dealer earlier due to the lack of available loaner vehicles. The car is now at the dealership and has been there for nearly three weeks without any updates or contact from the service team. The transmission is available for inspection, and documentation of the issue exists. The malfunction has created safety risks during normal driving, including delayed acceleration when merging into traffic and unexpected gear disengagement at speed. These conditions compromise vehicle control and increase the likelihood of a collision. Additionally, the vehicle produces a persistent squeaky noise from the accelerator pedal during operation, which could indicate underlying mechanical stress or a deeper linkage issue. The sound is both distracting and concerning, especially during highway driving or sudden acceleration attempts.

On June 10th I drove my vehicle to work downtown Cleveland (no issues). Got home around 1 pm and had to leave at 3:30 to get my daughter from school. As I got in my vehicle I started to go in reverse and received all of those notifications and my brakes went completely out and I had to slam it to the floor to stop it was so scary and I thank god I wasn’t on the road or with my children!! I called the dealership the next day and they finally had my vehicle towed on the 12th of June. Once my car was there “the error messages disappeared and it was fine”. I did not feel safe taking the car back so they kept it another day and had the technician driving it around, still nothing until he washed the vehicle then it happened. After doing a ton of my own research others have stated the 2025 traverse has the same issue and they had to get the master cylinder replaced so I mentioned this to them at the dealership. The lady called me back and said I was right. They put me through Hertz for a rental and I found out today they didn’t even order the part until the 20th. This is very frightening and should be a recall immediately! I can’t imagine if I was driving 70 mph and this happened I could’ve died or killed someone else!

Vehicle electronic rearview mirror continues to turn blue during operation and show an animation to flip back to normal mirror of mode. Dealership has looked at and stated known defect no current solution to fix concerns have been noted, but there is nothing to be done. Main touchscreen continues to glitch during operation, causing distracted driving dealership has looked at and stated concerns have been noted, but there is nothing to be done. It is a know defect.

Rear cross traffic alert system not working. No alerts when backing up and oncoming traffic
