Engine And Engine Cooling Problems of Chevrolet Traverse - part 1

After refueling we re-entered i495 northbound. While traveling in the fast lane of traffic my vehicle shut off. I lost all power, including the ability to use on-star. The vehicle refused to start for thirty minutes. This problem repeats within a mile of refueling. The vehicle has been taken to the dealer. The first time the said it was a sensor in the stable trak. This last time they claimed a bolt on the battery was loose. There was no pre-warning the car just stopped in rush-hour traffic on the busiest highway in America.

Limp mode. It doesn't have speed only goes about 10-20 mph, doesn't give any gas it'll stall act as if it wants to shut down. Transmission shift cable. Stalls want let me get gas or nothing slowing down in traffic, it just gives up. No. Yes. Others check engine light, stabilitrak/traction control system, abs sensor whenever the check engine light came early part of December.

My 2018 Traverse has had several issues the past few years such as the electrical components in the car turning on and off randomly, a shift to park message which has been fixed twice, and the most current problem is the transmission. I was out of town 160 miles away with my family of 6 and we were about to drive home when the engine started to sound forced while I was driving. It wouldn't go past 30 mph and I had to quickly and safely get off the road and look for a mechanic. Had we already gotten on the freeway my family would have been in much more danger. After driving cautiously to 2 mechanics they referred us to a transmission service location. We had to leave the car there for several hours and came to find out that the transmission needed to be replaced and it would cost anywhere between $4,000-$9,000 depending on if they try to fix our transmission or replace it with another transmission and the cost would depend on the warranty years. We ended up getting it towed home so that our local mechanic can take a look at it. We still haven't gotten it fixed because the repair cost is so high and we can't afford it. For being a 2018 and only having 65,000 miles we should not be having transmission issues. We also took it in to our local chevy service dealer who confirmed the transmission needs to be repaired or replaced and an accurate cost is unknown until they open it but the first estimate was $10,000. My vehicle is available for inspection upon request. I did see there was a recall for transmission issues for this make and model but it doesn't come up for my VIN. I really hope that Chevrolet can apply the recall to all VIN numbers affected because it is a very costly repair and has put my families safety at risk. It should not keep happening to others.

This has happened two times. Driving down the road between 35-55mph. "speed limited drive with care" no cel. Took to dealer, advised with a cel or no codes nothing they could do for it. Multiple nights I get home and the fan stays running after engine shutdown. Engine overheat within 10 min of drive time. Oil smells like fuel. This time engine throttles back and nearly caused accident with not being able to merge.

Broken exhaust pipe, there is a recall number for some 2019 Chevrolet Traverse manufacturer recall number: n212356540 for the same issue, good up to 150,000 miles.

The contact's son owns a 2020 Chevrolet Traverse. The contact stated that while driving at various speeds, the vehicle made an abnormal rattling sound, and the check engine warning light was illuminated. The vehicle was initially taken to an independent mechanic who could not perform the repair. The contact was referred to another independent mechanic, where it was diagnosed that a crack in the catalytic converter had caused a defect within the exhaust manifold. The contact was then informed that the failure was related to technical service bulletin number: pip5681c and was referred to the dealer for assistance. The contact had taken the vehicle to the dealer, where the contact was informed that the vehicle no longer qualified for the TSB repair due to the mileage. The manufacturer was notified of the failure and made the same assessment. The contact was then referred to the NHTSA hotline for assistance. The vehicle had yet to be repaired. The failure mileage was approximately 90,100.

My engine light came on. When I get gas the car will not just start there is a fuel leak code and a valve code. Getting looked at next week at the dealer.

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.

The vehicle just suddendenly shuts down when driven on the freeway, according to tillery Chevrolet GMC the engine cracked and needed to replaced for total of $17,291. 94.

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.
