Other Fuel System Problems of Chevrolet Traverse - part 1

Ive got this vehicle on 5/12/2025 and all of this need to be done catalytic converter replacement. During inspection found loud exhaust on startup. Upon further inspection found bank 1 catalytic converter cracked causing exhaust leak. Both exhaust front pipes damaged as well(broken mounting brackets between both pipes) . Recommend replacement of catalytic converter and both exhaust front pipesbrake system fluid exchange-performed pressurized fluid exchange of old brake fluid, removed moisture and air contamination from brake system. Installed new dot specific fluid to meet manufacture specificationsautomatic transmission service fluid exchangecf - cooling system service 6830/5881-01 includes flush cooling system, pressure test, check hoses, cap and check connection. Install cooling system corrosion control kit drain old transfer case fluid and replace with new fluid rear differential service this should have been done when the dealership got the vehicle, and it should be gm or berger responsibility. I am sure this was an issue to begin with.

On [xxx], my 2019 Chevrolet Traverse (VIN [xxx] ) experienced a complete transmission failure. The vehicle began to hesitate, jerk during acceleration, and then completely lost the ability to shift or drive. It had to be towed, and the dealership confirmed that the transmission must be replaced. This is extremely concerning because gm previously issued recall 20v668000 involving missing bolts in the start-stop accumulator of the transmission, which can cause fluid leaks and loss of propulsion—a potential safety hazard. Although my VIN does not show this recall as active, the symptoms and failure seem directly related to this known defect. I am requesting NHTSA investigate whether this recall should be expanded or reopened to include more affected vehicles. In addition to the transmission failure, I have had to replace the purge solenoid valve three times due to persistent check engine lights and fuel system issues, which suggests deeper reliability issues with emissions and vapor management. Lastly, there is now a hole in the exhaust pipe, which is affecting performance and may pose a safety or environmental concern due to potential carbon monoxide exposure. These multiple powertrain and emissions-related failures within the same vehicle raise serious concerns about the long-term safety, reliability, and manufacturing quality of the 2019 Chevrolet Traverse. I respectfully request that NHTSA investigate this model year and VIN range further. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Prematurely damaged exhaust system. Identical to special coverage adjustment n212356540 front exhaust pipe but my dealer and gm says that my VIN it’s not coveted.

This vehicle's canister purge valve solenoid has failed multiple times since we purchased it used in 2021. We've taken it to multiple Chevrolet dealerships for repair and the issue has not been fixed. The issue is once the part fails, the vehicle is unable to be filled with fuel completely or it sputters when trying to start and the engine turns off or it stalls right after placing into drive. This causes a safety concern. There are multiple articles all over the internet and social media about the purge valve solenoid specifically in 2018 Traverses with no recalls. This is disappointing!.

Check engine light code p0496 evap. Emissions system, high purge flow.

I believe my vehicle should be part of the recent gm recall for defective fuel pumps. I have been experiencing issues with my vehicle surging during acceleration, and stalling during idle. This has happened at stop lights and is a safety concern.

Owned brand new vehicle for 48 hours. Fuel injector failure on cylinder 4 at 120 miles on the dash. Check engine light was on. Vehicle is currently at dealership. Engine unreliable/unsafe. Dealer confirmed. Dealer stated up to 10 days waiting on parts. Unknown if further damage has been caused. Wife states vehicle had a rough idle. Diag code p0300, p050d.

Evaporation system is defective and the canister purge valve does not close completely resulting in environmental toxicities put into the air. A check engine light on and after 3 fixes the issue is still present.

I took my truck to the dealer back in 2022 for the specific reasons that the truck is being recalled now but my vehicle doesn’t qualify for the recalls. My vehicle has been having the same issues as the 2019 chevy Traverse recalls and I just saw that my truck is also leaking transmission oil which is linked to the 2019 recall but my truck doesn’t qualify. It started smelling like it was burning during the freeway drive today and when I got home, I noticed the oil leak I drive around 15 to 20 miles a day driving six children in my truck for safety and my truck is no longer safe to drive. I want to know why when I took my car in 2022 for the specific issues. They told me that it was pretty much all in my head that my truck was running fine and now I come to find out there are these recalls in effect, but my truck doesn’t qualify when the check engine light is on in my car for the specific reasons. I did contact the dealer where I took my truck in 2022 and they do have the paperwork to prove that I took my car and they told me someone would call me back to see what was going on. This was four days ago and nothing has happened and they also didn’t email me the paperwork like they told me they would.

The vehicle start stop feature is malfunctioning (I have a video) . When stopping or coming to a stop after driving through the city, at random times sometimes back to back when being stopped it goes down to 1 rpm then the auto stop feature kicks on and when it's time to depress the break to move again it malfunctions then sounds like a circular saw slicing through metal. At times you have put car in park hit engine ignition button to make it stop then wait a few seconds then start it back up. There's also a smell of strong fuel vapors coming in through the vents including defrost. Navigation stopped working ( turn by turn ) feature, also sounds as if the front end is knocking around going over speed bumps, the front right wheel has an odd rub sound that increases when accelerating. The gas also with a full tank depletes nearly within a day, and ait being a v6 should not guzzle $50 in fuel of 87 grade petrol. This thing is a rolling safety hazard. I have a wife and 6 children I transport daily. If something happens and we are injured I will sue your entire company general motors.

1. Driver side exhaust flex pipe braket 2. Exhaust leak 3. Yes. It has been replicated and diagnosed. 4. No engine light. There was a rattling and increased exhaust noise. A hole in the exhaust pipe at the bracket location was found. 5. This condition seems to be a common problem with this year and make which I am now having to pay $600 to repair.

Torque converter is bad. Codes will not come up when test ran. Mechanics mis diagnose the issue until it’s too late. Mechanic now doesn’t think it’s worth it to replace- wants whole new transmission.

Failed catalytic converter. I have had this part repaired multiple times and there is still a leaking issue. I have receipts from both auto repair shops and the dealership showing that this is an ongoing issue.

Purchased the 2020 Traverse on [xxx] from basswood in ft. Payne alabama. Under the guise of the salesman I was assured that the vehicle was in great shape, with no issues at all, and a very clean carfax. Well I'm new to purchasing a car via financing with a CO-signer in which he was assured the vehicle was in great shape. Well unbeknownst to us my household the car was nothing of the sort. Within a few days the start/stop malfunctioned to the point it would not restart 98% of the time without sounding like a demo saw, it's a dangerous problem and there's times we smelled fuel once we were able to restart the vehicle. The front right wheel assembly looks as if it were on fire and if that's brake dust and it has a grinding whomp whomp sound when in motion,that's really not good no wonder it's hard to stop at times. The front end sounds like drums when going over bumps, speed bumps, road imperfections etc. . On morning start-up there's an absurd amount of exhaust coming into the cabin area, the codes [p3055 and p3056] are registered from the computer of vehicle. Now the smell of fuel is blowing through all vents whenever the defrost is running or all vents are used front and rear, with the truck in motion. It was so bad today that my entire family had to pull over to a gas station and get fresh air our eyes were burning and my [xxx] son nose started to bleed. , so that's two parents and 6 children scrambling for safety. This is our only reliable vehicle other than an old 99 suburban that is hardly even road worthy anymore. I spoke with several people that have purchased vehicles and all agreed that the salesman and mostly the sales managers knew that the vehicle came from an auction and was never serviced nor inspected at the basswood dealership, which equates to them actively concealing major effects and problems with the vehicle in question. Just to make a one time commission on a fraudulent deal! they didn't provide any inspection papers to me! information redacted pursuant to the freedom of information act (foia.

I have had to replace my evaporative emissions purge valve 3 times on this my 2019 chevy Traverse. I have had it for a year and a half.

I took my vehicle to the shop for noise while driving. It was diagnosed as a cracked flex pipe. Upon research, the 2019 and 2021 models had recalls for the same issue, but not 2020. I did find a bulletin from gm including all models of Traverse stating the cause could be a faulty weld. My vehicle looks the exact same as the bulletin. This is a safety issue as a hole in the exhaust can cause exhaust to backflow into the cabin. I'm very lucky and thankful me and my kids have not yet been medically affected.

The transmission keeps stalling when the auto engine turn off comes on and I try to hit the gas. The transmission end cap had to be replaced. Then the shift to break kept going off when I was in park.

After buying 2022 Chevrolet Traverse premier started to notice a hissing noise. When I got somone to look at it I was informed that the weld on the bracket had broke. Since then due to vibration my exhaust manifold has cracked and I was quoted almost $2500 to repair it. I have noticed that I'm not the only one online but it's dealing with this issue that there are several people that have the exact same issue.

Dashboard notification indicating tighten gas cap, and then check engine light comes on. Took vehicle to get scanned and code says evap leak, took to mechanic all issues were fixed including replaced gas cap as suggested by many chevy Traverse owners who have the same issue. 30 days later now same issue is coming up. Researched online and it seems that many other owners have experienced this and fix is only temporary.

The fuel gauge in my vehicle is not functioning correctly. It is showing that my fuel level is very low/empty even with a full tank of gas. I took it to the repair shop and the it had the codes p0452 for the fuel tank pressure sensor circuit and p0463 for the fuel level sensor. The repair shop replaced the fuel pump module which did not fix the problem. They suggested it appears to have an ecm issue. This exact problem is a recall on the 2014 chevy Traverse however my vehicle is not included in this recall.

My 2020 Traverse has the exact same issue as the 2019, and 2022 models, both of which have active recalls. I contacted chevy and their response to me was that there was no recall on my model.

Check engine light keeps coming on for a small evap leak. When putting car in park and turning car off, warning message comes up saying shift to park so I have to wiggle the shifter until the message goes away. Tailgate some times does not close when pushing the tailgate button. Remote start does not always work.

The contact owns a 2023 Chevrolet Traverse. The contact stated that while starting the vehicle, a strong unknown sound was noticed coming from the pipes in the front area. No warning lights were illuminated. The vehicle was taken to an independent mechanic who inspected the vehicle and advised to take it to the dealer. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 30,000.

Vehicle has had multiple recalls one recall to do with fuel pump was supposed to be fixed but came back and new recall still no remedy and it can cause death. The vehicle is very unsafe.

Faulty exhaust issues.

The exhaust pipe, gaskets and muffler. Yes, at times we do smell the exhaust inside the vehicle and a loud sound coming from the engine when the vehicle is in motion and on standby. Yes they were notified and are still waiting for parts to have it repaired. They advised to continue driving my car and refused to provide a rental to use during the downtime due to my ‘issue’ not covered by my warranty or extended warranty because my vehicle is over 36k miles. No warnings were on in the vehicle to notify me, I just noticed a weird sound as my car would start up when the vehicle is started and never stopped.

It has a leak and having electrical issues. Everything else unknown.

Transmission shudder.

The vehicle is equipped with auto stop technology that the driver can’t disable. While driving, the system is designed to initiate auto stop when vehicle comes to a stop. When my foot lifts off the brake to proceed, the engine kicks back in and vehicle moves forward. Two weeks ago at a stop, the engine did not kick back in. I had to put the car in park at the light and after several attempts to push the ignition button, the engine finally kicked back on. The vehicle had the same issue later that day so I scheduled with the dealer for 4 days out. No warning lights came on. My onstar app did not produce any error notice. Meanwhile, I saw a video to override auto stop, put vehicle in low gear 6. That’s what I did to get through to appointment. By day 3 (dealer is day 4), I returned to vehicle after an hour meeting and it didn’t start at all. The check engine light turned on, not the battery light. Had vehicle towed to dealer who said the only alert was a bad battery. (battery is 16 mo with 36 mo warranty & alternator 5 mo old). I replaced the battery. Picked up vehicle from dealer and 5 miles away at a stop, vehicle shut off. I put vehicle in park, pushed ignition button and engine turned back on. I thought it was a fluke. 6 days later the vehicle turned off at stops on four separate occasions. Each time the battery was fully charged. On one last instance at an intersection stop, the vehicle shut off, would not restart when I pushed the ignition button, brake pedal became stiff, and dash lights and radio were completely off, as if the battery died. I let the vehicle sit at the intersection for 30 seconds before trying the ignition button, and it finally fired up. To get home, I put it in neutral at each stop to keep it from going into auto stop. This issue is not generating an “error” on the computer so dealer techs have no idea what to do. When I bypass auto stop by shifting to neutral at stops or driving in l6, there is no issue whatsoever with the vehicle.

I had 2 mile hr front side inpack in a parking lot whitch pushed me into anther parked car . Then at that point my car went into at a high rate of speed . I had both feet on the break no help . I proceeded to hit other cars after the 3rd and 4rd car it finally quit . This was at a small airport thank got no one was coming out of the airport . I did everything I could to stop this car . It just kept picking up speed .

Pm409 code purge vavle . I replaced the purge vavle and gas cap the engine check light is still on . Their is a recall on the purge vavle emissions system.

Catalytic converter failed, 3rd time in 2 years. Vehicle began losing power while on interstate. Issue has been confirmed by dealership inspection. Issue has been claimed by many other owners of this make and model but no recalls issued or warranty coverage for known issue. Check engine light came on just as issue began while driving with my family.
