On 10/12/24, I received an error code that my charging system needed serviced. I was about an hour from my house when I saw the error. I immediately turned on the voltage display and it said the voltage was 11.8. As I was driving home I had an additional error message that said entering battery saver mode. Luckily, I made it home before I was left stranded on the side of the road in the middle of the night. With only 57,323 miles on my car, I had NO idea it would be the alternator. I took my car to Auto Zone to have the battery tested and they said it was fine. I had my mechanic check on Monday 10/14/24, and it turns out the alternator was indeed bad. S
2020 Chevrolet Traverse electrical complaints
Page 2 of 2: complaints 11 to 28 of 28, newest first, as owners wrote them.
My rear exhaust manifold cracked, was told there should have been have been a recall on them bc they are defective. GM is covering 2019 and 2021 Models, but not 2020 models. I had to replace my alternator at the Chevrolet dealership 6 months ago. In the last month, have had the shift to park message come up on my car and that has something to do with the transmission.
When putting my Traverse in park, the car will intermittently say "shift to park", causing me to have to put it back ion reverse, put it back in park and hope it works. The car will not shut off if it says it's in park, causing you to be stuck in there. Also could cause it to not start if the vehicle thinks it's not in park. To note as well, there is already a recall out for 2018-2019 chevy traverse models, along with others. This needs to be extended to newer models as well.
The car has started to show a "Shift to Park" message on the dashboard when turning off the car. The car won't shut off until you give it a couple minutes and try again. This seems to be a consistent error with chevrolet models with a few years older and newer getting the recall.
Car battery drained after it sat unattended for 3 days. A jump-start started the car normally and it functioned normally until turned off. Once turned off, the hazard lights would randomly turn off/on, the door locks would randomly lock/unlock, and the parking lights would randomly come on. Replacing the primary battery had no effect. Outcome: Due to seemingly poor design, a drain pipe passes over the BCM (Body Control Module) and drips water directly into it. The mechanic indicated that this is a known issue to Chevrolet, but I do not see any information in the federal safety agency about it. Hefty replacement part/labor cost.
Sunday night 4/7/24, I was on my way to the emergency department with my 5 month old baby to be seen. 30min into my drive i came to a stop light when my truck completely shut off (BLACKOUT) No Power, NO LIGHTS not even my hazard would turn on, my car wouldn't go into park or allow me to press on my breaks it was like they were glued stuck. all my doors locked and I couldn't get them to open, not even manually because of the nobs that go all the way in. I couldn't put the car into park or anything just got locked in my car and I couldn't even hit the OnStar because everything was off! I started to see cars coming from a distance so i started to panic because they were going to rear end us really bad, so i broke the driver window and went to warn drivers to please stop by putting myself at risk to get hit by a car because i didn't know what else to do, i had a 5month old baby in the back seat that would have died if I didn't pull her out and we got hit. I started to scream for help because it was dark and we were stuck. two cars came inches from rear ending us, which caused an accident between the two vehicles. thankfully a police officer was passing by and got behind my traverse to stop traffic. but if it wasn't for the cop i don't know what the outcome would have been. THIS IS A HUGE SAFETY ISSUE. IF THE CAR WAS ON FIRE WE WOULD HAVE BURNED. THIS NEEDS TO BE RECALLED ASAP. Why would they design a car where you cannot get out. and why did it shut off like this. ???? I NEED ANSWERS PLEASE. I'M TERRIFIED TO DRIVE MY CAR AND THIS WAS A $38,000 VEHICAL THIS IS NOT OK!!!!
Alternator failed within 3 years and only after 45,000 miles. GM refuses to take any liability even though several other people experiencing same defect and part rated for over twice that length of period.
When the vehicle is shifted into "Park" the information system reports an error code "shift into park" and prevents the vehicle from being turned off. On the opposite side of the spectrum, there are times when the vehicle fails to start with error code displayed "shift into park" even though the vehicle is infact in park. The error code is sometimes resolved when the shifter levers forward facing button is actuated multiple times. This false error code is a grave safety concern as it build complacency within the operators. This could potentially lead to an operator ignoring a true "shit into park" error code as a false one and exiting the vehicle while it is actually in gear or neutral and cause death or injury to an innocent bystander or the operator! Please investigate this error as it has apparently existed and been well documented in the Chevrolet Traverse since at least 2018. Yet Chevrolet still fails to acknowledge or resolve it!
On 02/24/2023 in the middle of a storm our Headlights suddenly going out for a few hours while driving the car when the knob is on AUTO. Had to turn them on manually. Then the next day we turned the car on they worked just fine. A couple hours later they went out again. Today 02/26/2023 they’re working again. This is a safety issue.
There is an electrical short that keeps shutting down the stereo. I bought my car new Dec 2020. In the summer of 2022 I was driving my car and the stereo and dashboard suddenly shut off. I pulled over and it came back on after a few seconds. I was told by Chevrolet first that the stereo was faulty and then that there was an electrical problem affecting the stereo. On Dec 24, 2022 I was driving my car and again the stereo suddenly shut off and started power cycling, turning off and turning on several times. I took it in to be inspected on Dec 26, 2022 and was told that there was an electrical issue affecting the stereo and they would have to get approval from the warranty company to have it replaced again. It was finally replaced yesterday 02/17/2023. Now I’m wondering if there’s an electrical problem what’s going to be affected next or how long til it causes problems again. I don’t feel safe driving my children in the car if it’s having an electrical problem.
I was driving down the street and my car started to randomly jerk. When I pushed the gas the car got slower. Once in a safe place I pulled over and sat there for a few minutes. When I accelerated again the car had a sound like the car was speeding up, but there was no speed. It drifted. So I crossed the traffic light and pulled over again. I turned the car off. I waited for about 5 minutes, turned the car on and that's when the engine light came on. I had to drive slower to make it home. Once I made it home I put the car in Reverse and noticed that my back up camera was not working as well. I am so frustrated.
This vehicle has completely lost power and stalled on the freeway twice. The first time, I was with my wife and children when it happened on the highway. The vehicle stalled in the far right lane of traffic and it wouldn't restart. We had to risk our lives and push the vehicle off the freeway and onto the shoulder while other vehicles raced by. We are fortunate that we did not die or become seriously injured. The second time the vehicle stalled on the highway, my wife was crossing the highway and the vehicle once again lost all power and shut-off. She is fortunate that she was not killed in a T-bone collision. The first time, there was a dash warning stating to SERVICE ESC. The second time, there was no warning lights or dash illumination of a problem beforehand. The vehicle has been taken to the Chevrolet dealership twice. They ran a diagnostic and stated the starter was pulling too many amps which caused the vehicles fuse block to blow, resulting in total failure of all vehicle components. Total repair cost for first repair was approximately 1,000 dollars. We are awaiting the service advisors diagnostic for this second incident. The first repair is covered under a 2 year unlimited mile warranty so hopefully when they replace the starter and fuse block this time, they will also find the root cause of the problem. I feel as if our lives and well-being are in jeopardy since the first incident and we no longer feel safe driving this vehicle which has stalled twice during highway conditions. I am confident that we will no longer be GM consumers due to these life risking incidents.
The contact owns a 2020 Chevrolet Traverse. The contact stated while driving approximately 45 MPH, the check engine warning light illuminated. The parking brake symbol also displayed on the instrument panel. Additionally, the instrument panel then went blank. The contact drove the vehicle to his residence and parked the vehicle. The contact then noticed that after turning the vehicle off, the radio remained on and the contact was unable to manually turn off the radio. The contact attempted to start the vehicle the following day and the battery was drained. The contact had the vehicle jump-started and drove the vehicle to a dealer who attempted to diagnose the vehicle however, all the data had been erased. The vehicle was not repaired. The manufacturer had not been informed of the failure. The failure mileage was 29,700.
All 4 doors do not lock or unlock, keyfob only works to open liftgate.
The surround vision system not working. It was occasionally, now it does not work at all. We only get a dark screen with a red hazard triangle. It started the day we bought the car and the dealer claims they have another car like mine ahead of me with the same problem. Since the last week of december they have claimed that gm does not have a fix for this issue. I made a complaint with my chevrolet customer service case # 9-6485705057, but I don't get any answers from them either. I am not sure if this system is tied into the adaptive braking/cruse, but I have yet to have the vehicle take action in that regard. In checking that out. I got way closer than I felt comfortable with, I keep waiting for the car to react to the closing distance but it never did. I backed it off myself. I was well within two car lengths of the vehicle ahead (55 MPH) and closing in at about 3 or 4 MPH. If you have to be closer than that for it to activate then I will not be using it. I have been dealing with this dealership for several years, and have purchased 3 automobiles from them. They have performed the regular service and warranty work on all of them with no problems at all. For them to have an issue fixing it is not typical of the service I have received from them in the past. So, when they tell me gm does not know how to fix the issue. I have to believe them up to a point. With the small windows in the back of this vehicle. Visibility is extremely limited, and it is a safety issue. If they can't keep the basic surround vision system working. How are they going to maintain autonomous vehicles to a level that protects all involved?

The manufacturer was made aware of the failure and provided a case number. The failure mileage was approximately 1,100.
Have broken down and been towed 4 times now. Come to stop on road- auto-engine shut off engages- car dies can not restart. Fuse blows-- first occasion was told bad fuse- replaced, next occurrence same fuse blows- was told faulty starter drawing too much power and blowing fuse upon restart- starter replaced was told that will fix problem. Next occurrence- car would not start from parked position- was told whoever replaced starter ( buzz chew checy- southampton ny) did not bolt down starter- loose connections-- was told problem fixed. Last occurence same as first 2- car stopped in traffic- auto shut off engages- does not start /car dies. Unfortunately 2 of these breakdowns were on highways during rush hour-- with your kids in car. Last occasion almost rear ended on multiple occasions as nighttime, stuck in middle lane on major turnpike.... 10 yr old will not get back in car- has fear of god. Was told by chevy buzz chew in southampton, nessenger chevy 112 problem was fixed. Do not want to endanger my family anymore.
Rear camera stopped working aide senors stopped working. After several months of trying to fix this they finally might have this on the recall list for some cable kit, which they did not totally put on mine becuase due to covid they are backed up on manufacturing, I do not rely on back up camera but it is nice to double check.have had it in 4 different time to be fixed also raide continue to have problems. Been replaced 3 times.
