Engine And Engine Cooling Problems of Chevrolet Traverse - part 1

My car is leaking coolant. There is no warning light or anything. Had to be towed to the dealership. Dealership confirms the truck is not driveable and needs an upper radiator hose which is on backorder until January. There aren't any loaner vehicles according to the dealership.

Coolant radiator failure at 15,000 miles no available fix from Chevrolet.

Engine light came on . Warning low coolant turn car off engine over heating. Fan still running after turning off. Happen several times. Serveral days. Took in in to dealership because still under warranty. No longer car available despite under warranty. Also breaks alerted low break pad life in around July 2025 and took it in the dealer and said it was a update not completed.

Engine overheating light comes on, car leaking fluid. Possible radiator or radiator hose. Unsafe to drive breaks are squeaky and bad.

Completely disgusted with chevy Traverse. Upper radiator hose busted and radiator leaks at seem, squeaky brakes since day one purchased then sensor on brakes went bad causing it to say brakes are less than they actually are says 18% and it’s actually 88% caused the engine light to come on ppl can’t afford a payment and be at the dealer all the time and without transportation. It’s my only vehicle and I need it fixed but everyone says part is back ordered or something this is a shitty vehicle chevy needs to pay to replace brakes sensor hoses and radiators even if it’s past factory warranty these vehicles cost to much not to last past 36,000. Ridiculous there needs to be a recall this is becoming a very well known problem chevy should have to cover to fix it and make it right and provide a vehicle while it’s in the shop. Very upset with chevy and it’s quality and this needs to be recalled ASAP.

Squeaky breaks coolant leak engine heating warning check enginelight comes on after each gas visit car sounded super load when engine is running due to constant coolant leaks car doesn’t feel safe to drive with 4 young kids!.

Bought vehicle on 11/28/25. By 11/30/25, brakes squealing and large puddle of coolant in driveway. Took back to dealer on 12/1/25, told special radiator hose that is on backorder all over country. Unknown eta.

This vehicle is unsafe for two reasons. First, it slams you on brakes and puts you in park at random times. Middle of road, parking lots, etc. This puts you at higher risk of someone hitting you. The second thing is when pressing the gas when taking off after a stop, the rpm’s jump up and the engine revs up, but the car is barely going. Not safe when crossing intersections along with many other times. Both of these puts mine and my families safety at risk along with others on the road. No warning signs, lights, etc. Car is in shop for second time. First time on November 28, second time on December the 11. Still no answer on a fix. Just that they think they may know the cause. The dealer has gotten the car to reproduce these issues.

Radiator leaking fluid from top right of radiator. Hose is dry where it connects to radiator, but coolant is leaking down the right side of the radiator, starting at the top.

The contact owns a 2026 Chevrolet Traverse. The contact stated that while driving at 35 mph, the check engine warning light illuminated. The vehicle was taken to the residence. The contact stated that while making a right turn into the dealer to have the vehicle diagnosed, the brake warning light illuminated. The vehicle was diagnosed, and determined that the brake master cylinder needed to be replaced. The vehicle was not repaired because parts were on back order. The manufacturer was notified of the failure. The failure mileage was 500.

The upper hose is leaking and vehicle is losing coolant.

Ome customers may complain of a rattle or exhaust noise, a cel/mil on, or repeat concerns of lean codes or converter failures. The cause for these concerns could be a broken or poor weld with lack of penetration on the bank 2 exhaust. Issue is exact same as listed in bulletin pip5681a.

To date, I have brought the vehicle to the service department four times, primarily due to the check engine light and other critical malfunctions. Below is a summary of the incidents: first visit (approx July 2024): the vehicle suddenly lost acceleration while I was in traffic, leaving me stranded in the roadway. This posed a serious safety risk. The vehicle remained in the shop for 28 days. Second visit (September 29, 2024): multiple warning lights illuminated, and several diagnostic codes were detected. Third visit (do not recall the issue): will find work orders if needed most recent visit (December 3, 2025): a coolant leak caused the temperature gauge to spike, resulting in the air conditioning shutting off due to overheating. The next day the check engine light came on. I had no warning prior to the guage spiking. In addition to these major issues, the following concerns remain unresolved: brakes continue to squeal. The dealership advised this is normal and that front brakes wear faster. Reverse sensor activates randomly, causing the brakes to engage abruptly. Also the front crash sensor triggers without any obstruction ahead. The dealership recommended disabling this safety feature. These recurring problems raise serious safety concerns and significantly impact the reliability of the vehicle. The advice to disable safety features is unacceptable and does not address the underlying issues.

Purchased the car in August 2025 and have had into service 3 years for the same issues. When driving the car, the rpm will get "stuck" between 5-6 when only driving 20-30 mph. Once I slow down/brake, it will jump into a park effect, but still be in drive. The car has been inspected by chevy 3 times, but they can't get any fault code on the vehicle, so they can't "fix" the issue. This puts myself and my small children at risk because if it jumps into the park effect, while still in drive, I can not move and someone could rear-end me. I do have video evidence.

Flex pipe issue.

My vehicle began to leak heavily from the front drivers side- under carriage. No warning lamps, on star notifications came on but the vehicle was loosing a lot of coolant which could result in the engine overheating. I took it to the dealership and they diagnosed that I needed a lower radiator hose- this needed to be replaced. The part that is needed is on back order until end of December.

Coolant/radiator hose leaking - noticed leak on driveway , no messages or warnings , leak is being reported on numerous chevy Traverse vehicles, needs a recall before it becomes a safety concern.

Known issue with the front timing cover leaking. Confirmed by dealer and local repair shop that it is an issue they see on these engines all the time and is a manufacturing problem.

Timing cover / valve covers. . . Had to drop the engine. . . 5k for 100,000 miles. Other 2019 Traverse have had issues for recall but not my VIN. If some VIN numbers have been recalled, then all VIN numbers with the same issue should be covered.

Upper radiator hose leak with 20k miles. Coolant reservoir was completely emptied. Hose needed to be replaced on top of a parts not in stock. No warnings to overheating or coolant leak. Also brakes squeal since day of purchase.

My 2024 Traverse was delivered with defective third-row seat headrests that do not return to their normal upright position after being folded, compromising passenger head and neck protection in a collision. On October 28, 2025, the vehicle developed a coolant leak confirmed by the dealer, but repairs have been delayed due to a national parts backorder, creating a risk of engine overheating or sudden breakdown while driving. Additionally, the front brakes began squeaking excessively about one year into my ownership, and the brake pad wear sensor shows only 18% life remaining at 18,454 miles, which raises concerns about reduced braking efficiency and increased stopping distance. All issues have been reported to an authorized dealer and remain unresolved except for the third-row headrests. These conditions pose significant safety risks to occupants and other road users.

Weld on exhaust was faulty the bracket malfunction. The exhaust system has leak and rattle with exhaust noises, causing the converter fail.

After only having the vehicle for one year, we found a big puddle underneath our vehicle. Not knowing what this liquid was and just thinking that it was the air conditioning. We continue to drive it while driving at one afternoon. The car told me to stop immediately as my engine had overheat overheated. We are now stuck in a rental until further notice due to the upper radiator hose needing replaced. It concerns me that a vehicle so new is out of order for so long that if it were to have any more issues, I would out of a vehicle again.

Our Traverse spontaneously caught fire.

Transmission went out does not move at all with only 49,000 miles on the car the car always had sifting problems. Brought the car brand new off the lot. One owner. Before the transmission went out when I will stop at the red lights or stop signs the car would just take off for no reason. With my foot still on the brakes or the car would just stall when I am driving it right in the middle of traffic. GMC needs to held accountable before some one gets killed. ??????.

The car has 45,000 and started burning oil. The car is in brand new condition and well under mileage for an issue of such to be occurring. Took to car dealership where purchased and was told $8,500 fix!.

My car has twice been fixed with this shift to park message and now it is in the shop once again to be fixed!! and this has also had the torque converter fixed twice now. And it is still doing the same issues. This needs to be something that chevy is replacing. I am a single mother and can’t afford all these problems and yet I keep having to make a car payment and get these things fixed.

Transmission is slipping while driving.

The contact called on behalf of a customer who owns a 2018 Chevrolet Traverse. The contact stated that while the vehicle was parked, the customer noticed a huge oil leak on the ground where the vehicle had been parked. No warning lights were illuminated. The vehicle was taken to the independent mechanic where it was diagnosed with a failed low pressure oil sensor. The contact stated that the low-pressure sensor had separated. The customer was informed that the low-pressure oil sensor needed to be replaced. The vehicle was being repaired. The contact stated that it was the second similar vehicle that was recently repaired for the same failure with low mileage on the vehicles. The manufacturer was not made aware of the failure. The failure mileage was approximately 63,000.

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.

Maf sensor went bad on my 18 to Traverse. I was told not to change the sensor that it was the manifold. Two days later I'm being told that my transmission is bad. I am in process now if getting it rebuilt. Needless to say I'm out a lot of money.

I purchased a 2018 chevy Traverse with 6 miles on it. I keep my vehicle in mint condition and maintenance as needed and required. Recently in the past few months my car has been bucking when shifting gear engages in an automatic transmission. I took to dealership, and they stated it was the torque converter, and my vehicle has exactly 20,270 miles only. Not even passed the 36,000 marks but over 36 months. I bought an extended warranty thru dealership which now sending someone to dealership to verify that this is infact a torque problem which were found 2017 and 2019 but not 2018 is hard to believe. They will be keeping it for 7 days and already had a recall for 2017 and 2019 so are they stating it only occurred in those years, and they fix the 2017 but then it skipped 2018 and jumped to 2019. Why have I not received any recalls since I buy most of the GMC vehicles and lived in the same home for 35 years. Its awfully strange that I never receive any recalls when I owned silverado truck, savana high top van with special needs lift, pontiac torrent, chevy Traverse. The warning lane change or the blindspot warning shut off too. Was told to wash the window on the front and on the camera back and did not clear the sensors. Was told to check transmission fluid and it was fine and I do oil changes since my dad taught us every 2500 -3000 depending on driving and if only little mileage check it anyway monthly with the dip stick. Like I stated I keep my car in mint condition and safety is number one issue in family due to the special needs son riding in it.

Broken catalytic converter at joint with exhaust pipe. Manufacturer defect with the exhaust piping.

Exhaust pipe bracket that is welded to both exhaust pipes broke off allowing firewall side catalytic converter pipe to crack near the head of the engine.

Exhaust started to rattle, now it is a loud clangy exhaust. Clearly a part has separated or there are holes in it. Dealership told me my car has a repair out for that for years 2019, 2021, 2022 and 2023 but not my year, 2020.
