2020 Chevrolet Traverse complaints

Hole in the flex pipe which seems to happen with them all as there have been recalls on years 2018,2019, and 2021.

The exhaust broke, sounded like I was a race car driver. Muffle making loud noise while parking and driving

Faulty exhaust issues

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 ANS

After routine oil change in January 2023, rattling noise under car was noticed. Returned to dealer who stated front mounting bracket had cracked. Was informed by technician to take vehicle to muffler shop nearby to have bracket welded due to them not "doing" weld jobs there. Had both bracket and crack in front pipe repaired in June 2023 mileage 68,660. February 2024 Noise returned and steadily grew louder. On March 3, 2024 while turning onto neighborhood road, loud bang was heard then car sounded like it was roaring and was barely moving when pressing gas. Made it to driveway and at ignition cut off, gurgling fluid sound was heard. Towed to Hardy Chevrolet on Tuesday 03/05. Mileage 82,059 Still waiting on full diagnostics but front pipe has completely detached at right passenger cat. Bolts stripped out? I will not be able to pass State mandated emissions testing until repaired. This problem was recalled for the 2018, 2019 and 2021 vehicles, but for some reason not 2020 for the exact issue. The dealership wants to charge for a known safety issue. 2021 - GM Special Coverage (N222385510) 2019 - GM Front Exhaust (N212356540)

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.

In a collision where there was front end damage, no airbag deployed

While driving at low and highway speeds, I began hearing a rattle under the vehicle, along with a loud exhaust noise. I looked at the undercarriage of the vehicle and observed a broken bracket on the exhaust pipe causing a hole in the exhaust pipe. I searched and found this was a common issue with this make and model of vehicle.

The front mounting bracket has separated from the front exhaust pipe. Because of this the exhaust pipe has developed a hole around the bracket, leading to a leak and increased exhaust noise. My check engine light is on constantly and will not be able to pass State mandated emissions testing until repaired. This problem was recalled for the 2018, 2019 and 2021 vehicles, but for some reason not 2020 for the exact issue. The problem has been diagnosed today 2/12/24 by my dealership but they want to charge for a known safety issue. 2021 - GM Special Coverage (N222385510) 2019 - GM Front Exhaust (N212356540)

The transmission failed in the middle of me driving the check engine light popped on and started jerking and accelerating and slowing down in the middle of traffic. It is available for inspection. Stopping randomly and jerking as soon as the light popped on. I am about to be out of thousands of dollars for a 40000.00 car that I'm still paying on always kept maintenance up and just had an 180.00 inspection at dealership prior to this no mention of a transmission failure prior. Everything came back good so this is frustrating several other 2020 traverses have been recalled due to transmission I am not sure how mine isn't included for same year. It conveniently happened right when it wad out of warranty.

The transmission went out, when going out it causes the vehicle to jerk while at a high speed of 60mph and then after the jerking it stops in the highest gear almost causing a wreck and this all suddenly happens on an interstate.

Due to a death in the family, we were traveling back from a funeral. We were miles away from another freeway change when a deer came from the ditch and darted in front of my vehicle. With no time to react, I braced for impact. Going at a high rate of speed, I was bracing for airbags. At the time of collision all the safety features engaged. The seatbelts locked in place, hazard lights turned on, and my vehicle was slowing, but my airbags did not deploy. They did however release a white powder substance. I was safely able to get my vehicle off to the side of the road and evaluate the situation. My husband was moaning and grunting in the passenger seat. My three children are scared, frightened and worried. As we were attempting to unbuckle and exit the vehicle to assess the damage, we were unable to free ourselves. As the seatbelts locked, and had no wiggle room to disengage the latch. We had to move the seats back, to allow room to unbuckle. With the impact we received and the size of the deer struck. The insurance has deemed the vehicle a total loss. After many questions, and multiple attempts to get answers. All I have is the airbags should have deployed, with the evidence through the car with the white powder at airbag locations. As I thank to not be as injured as we could have been. Having my whole family walk away with minor bruises and many aches. My heart is broken, I am shattered and unable to process the incident. Having put so much faith in a vehicle to protect mysel

My vehicle along with many other make a stuttering feeling when accelerating at low rate of speed. This can lead to a bad transmission and causing the vehicle to cut off making a hazard.

In the past 3 years I have received 2 check engine lights giving a code of P0420, meaning the catalyst system efficiency is below threshold. Chevy replaced my catalytic converter in April of 2022… now a year and a half later they need to replace parts again. A catalytic converter is an important exhaust and emission component that is designed to burn up the toxic exhaust gases that come from the engine… carbon monoxide and hydrocarbons to be exact. I just found out today after taking it in for a second time that the first replacement of the catalytic converter was a defect on the manufacturers part. Every time I go in I have to pay the diagnostic cost and I feel as though I was sold a defective car. Catalytic converters are supposed to last the cars lifetime in some cases.

I own a 2020 Chevrolet Traverse. At the time of the incident, I was driving at 55 mph and heard a very loud and unusual sound. The vehicle then began to uncontrollably shake so I pulled over to the right shoulder. A truck driver pulled over with me as he thought it was something in his truck that had malfunctioned due to the intensity of the sound that it produced. At the rear right wheel of my vehicle, the metal rim was broken vertically causing the rim to separate into two parts. The tire is completely intact. Thank god, the outermost part of the rim that holds the nuts did not break and stayed completely whole and solid letting me pull off to the right shoulder. To put it into perspective, the wheel was left in three different parts. The first part was the tire. The second part was the cylindrical shaped metal rim that stayed inside the tire. The third part, being the outermost part of the metal rim, can be envisioned as a simple cap. There were not any warning lights that became illuminated on my dash. My vehicle has not been previously repaired or diagnosed by any independent mechanic or dealer. The wheel, tire, and rim are the original fabricated parts that came with my vehicle.

The contact owns a 2020 Chevrolet Traverse. The contact stated while driving 55 MPH, the contact heard an abnormal sound. The vehicle then started shaking uncontrollably.

The vehicle had not been diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 55,000.

Good morning, I have an issue with my 2020 Traverse that GM refuses to fix. I am getting warning lights from leaking exhaust. This is to due to weld defects. GM knows of the issue, they did recalls on the 2018, 2019, 2021 models but won't fix my 2020 even though it is the same issue. GM has a safety bulletin PIP5681 and PIP5681A for this issue. N222385510 is the number for the 2021 recall. The dealership has told me that this absolutely should be recalled but GM will not allow them to repair the 2020 under the same recall number. Thanks for your help!

I was told that my muffler needed to be replaced and not covered under warranty this vehicle is not even 3 years old yet and I need a new muffler my car sounds LOUD and the check engine light is now on.

When I place the car in reverse, the rear view image does not show on the display screen. This is a recurring issue when it’s approximately 75-85 degrees out. I did some research and found information on where you have done a recall of the 2020 Acadia for the exact same issue, requiring a replacement of the coaxial cable. I wanted to let you know the same issue is happening in the 2020 Traverse.

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!

The exhaust broke under 2020 traverse with 41365 miles allowing fumes to come up through the floor into cabin. You have a repair notice # N212356540 for this problem on 2019 traverse and # N222385510 on the 2021 traverse ...dealer says my 2020 is not covered. Please let me know why.

The exhaust pipe and muffler developed a hole in both exhaust components at less than 32k miles. This is a known design issue for the model as a previous model year had a special coverage adjustment on 03/2022 [XXX] . It is apparent this is a design flaw that wasn't fixed for the 2020 model year. GM has only offered 50% of repair costs. I am requesting the NHTSA to open review of exhaust failure for the 2020 model year of Chevrolet Traverse, GMC Acadia, and Cadillac XT6 that are equipped with the 3.6 liter V6 engine.

Vehicle all of a sudden started sound loud when accelerating on a trip home. Vehicle is 58K miles. Upon investigation, the vehicle was loud when starting as well. Mechanic determined front pipe under driver side had rusted and broken. Was told there is no recall, not covered under purchased extended warranty - $600 to repair. This should not happen on a vehicle this age. There are similar complaints about the same issue for the 2020 model.

Since Oct 2022, my backup camera has been intermittently working (it doesn’t work most of the time). I have taken it to the dealership and they replaced the coaxial cable in February 2023 but the problem keeps persisting. I have taken it to the dealership a total of 4 separate incidents and the problem has been reproduced and confirmed by the service tech each time. This last time, I was informed there was three codes showing up so they were not sure what the problem was. I was told that even though the service representative saw that the camera wasn’t working when the technician came it was working so they couldn’t do anything. I was told to bring the vehicle back when it did it again. It has constantly not been working properly since I brought it home. When the camera doesn’t work a a red triangle and a circle with a line through it displays on the screen. I feel as this is putting my safety as well as others safety at risk every time it doesn’t function properly. The inability to use my back up camera reduces my ability to see behind the vehicle. This increases the risk of a crash, injury or property damage when the vehicle is backing up. I have not been involved in any incidents but there have been a few near misses.

Months ago I was driving, my 2020 traverse I hit the brakes and I heard a weird grinding noise & my car started wobbling, I figured I needed my brakes pads changed, I took it to Waldorf Chevy they looked at the brakes and told me everything was good I didn’t need pads and everything was ok, they said sometimes the pads get dust on them causing them to squeak, and wobble, i had the front pads replace at a local shop they also looked at the back brakes and said the back pads were good, sometime later I was heading to work I stopped at a gas station and the car wouldn’t start. On the Chevy app it said my antilock brake system and stability control needs serviced which was weird it gave no warning I had it diagnosed the mechanic said the engine seized I towed it to another shop they said the same thing I towed it to Chevy they insisted it was the battery I told them it was the engine, they later said the engine seized but not before charging me $500 for a diagnostic, $371 battery plate. I got oil changes regularly and often did preventive maintenance.

March 30, 2022 I was driving on a highway with no other vehicles nearby and I heard a sudden loud pop. At first I thought is was a tire but no pressure changes on the screen. Few minutes later I heard a plinking noise and realized it was above my head and my sunroof had shattered. Luckily my visor was pulled across so I didn't have glass raining on my head while driving. Brought it into my dealership who sent me to a auto body glass division. The glass was on back order for 10 days and repaired on 4/12/22. I paid my $500 deductible through my car insurance. My vehicle has a front sunroof and a back moonroof that does not open. On May 15, 2023 I was driving on a country road and again there was a sudden pop. Again thought it was a tire but there was a gravel truck about 5 cars ahead of me but my sister was in the front passenger seat and did not see a rock or gravel. Rear moonroof had 2 small cracks on top but luckily again my visor was closed. We had a 30 min ride home so we tried to wrap plastic wrap around and over it but the wind got underneath so the hardware store told us to duct tape it and it worked well for about a week until the roof completely caved in on May 24 th. I called my dealership and the claim was filed for replacement with same glass company but now the part is on back order until mid July!!! I paid $300 for my car insurance and my dealership is keeping it and I traded it in for a new 2023 Chevy Traverse which I paid $19,000 for and hoping the glass will n

I was operating my vehicle at 70 MPH on the freeway, when I took my foot off the accelerater pedal to exit I could feel a pop under my feet and the engine started to make a lot more noise. I lost engine power and had to coast/idle to the nearest gas station. I went under the car and discovered a hole in my exhaust where there used to be a bracket to mount the exhaust pipes to yhe undercarriage. I went on a chevy Traverse Forum to discover this is a common problem. I believe it is unsafe to operate the vehicle with an exhaust leak that also creates loss of engine power and eventually leads to engine damage.

Took vehicle in for yearly inspection. Vehicle had 39950 miles on it. Vehicle would not pass inspection because of rear suspension adjustment link which could lead to accident. This problem is well known to service techs who inform owners this is a recurring issue at 40000 miles.

The driver's seat belt would not "buckle up" or latch into the buckle. This issue started a couple of months ago but it just seemed to be stiffer than the other belts. Then suddenly it started to release while driving. Then we were not able to get it to work at all. The dealership was able to get the vehicle in immediately and replaced the seat belt assembly. My safety and the safety of any of my family driving this vehicle was a risk of a malfunctioning seat belt. I don't know if it would have held if I were to get into an accident and I'm concerned about the passenger seat as well. Other than it being a little difficult to buckle up there were no other warning signs. The dealership replaced the part on 5/15/23.

Brought the vehicle in to dealer for oil change, and tire rotation. Dealer found that the rear toe links on the Traverse were corroded. It only has 36970 miles and is not covered under warranty which expired 36,000. This is a recall on numerous GM vehicles and GM should cover and issue recall on the traverse as well.

Cajun Red Paint Color has defect. Paint began showing white specks where paint is chipping off after only having vehicle for 3 months. Continues to get worse, mostly on hood of Traverse but also on sides.

P0420 warning light came on car exhaust has whole in it

I was in a collision at 60 mph and flipped through the air without hitting the roof and landed on my wheels. I had a car doing 80 lost control as he was passing me sideways and into my lane. The front on the car was completely unrecognizable z no side impact or sudden stop.

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.

Front exhaust pipe breaks at bracket due to poor design and ineffective welding causing exhaust leak, exhaust rattle, multiple trouble codes. Technical service bulletin PIP5681 and Special Coverage Adjustment N212356540 already exist for known problem.
