SERVICE BRAKES, WHEELS, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
I was driving along the Jackie Robinson Parkway when, on a curve, the car braked on its own and crashed into a wall, resulting in the total destruction of the vehicle. My son had to be hospitalized. This car had braked on its own before—at speeds of 10 or 15 mph—but I didn’t think much of it at the time; however, this time we were traveling at 45 mph when the

The contact owns a 2018 Chevrolet Traverse. While driving at 5–8 MPH, the transmission slipped. After coming to a complete stop, the vehicle hesitated to accelerate for five seconds before jumping forward 3–5 feet. Several unknown warning lights briefly illuminated. Additionally, the vehicle failed to respond while in reverse(R). The contact expressed safety concerns for his child who occupied the vehicle. An independent mechanic was unable to diagnose the failure. The failure mileage was approximately 148,000.

First issue-cracked catalytic converter caused leaking carbon monoxide inside vehicle. When I was driving I could smell strong, nauseating fuel smell and would have to drive with windows open to try and get fresh air. Took it to local shop for repair which cost $2700. After repair did some research and found special coverage warranty for 2018 Traverse for this same issue, however chevy told me because I took it to a third party they would not reimburse. Second issue-when car would go into gas saving mode vehicle would shut off quickly then start back up and all alert lights would come on (ie. engine light, parking light, etc.), vehicle would also show typed alert on screen something about power steering would be modified and drive safely. Recently took it to chevy to have it looked at, 3 issue were wrong, one being the purge solenoid needing to be replace. Because of known issue before, did some research and also found a special warranty coverage for 2018 traverses for this issue as well. However, my VIN is not showing any of these recalls so now chevy says they will also not cover this.

For months we have had issues with the known issue of “Shift to Park” which is a huge potential safety risk to myself, my children, and all of my neighbors who are ever remotely close to the vehicle. No dealer can resolve the known issue for this year/make/model. It has slipped from park to drive once but thankfully I was still in the vehicle. Additionally, at barely 100,000, my transmission has failed suddenly. After having the vehicle suddenly buck when driving down the road— again risking the safety of myself and my children, as well as other drivers around me- the check engine light came on. After being inspected, the codes coming up are P0700, P2723, and some other transmission related codes indicating there is an internal issue with the transmission. I am told I will need to replace the entire transmission and it will cost well over $9,000. This vin should have been included in the prior transmission recall for this year/make/model due to the negligent risk of the vehicle slipping out of park and slipping gears while driving. Please help.

I am submitting this complaint regarding a complete transmission failure in my 2018 Chevrolet Traverse (VIN 1GNEVGKW7JJ279077). The vehicle's transmission stopped functioning altogether, resulting in a complete loss of propulsion. The vehicle can no longer be driven and requires repair/towing. A sudden loss of propulsion can create a serious safety hazard, particularly if the failure occurs while driving in traffic. My mechanic has informed me that they have experienced multiple transmission problems with 2018 Chevrolet Traverses and that issues involving this transmission are still being researched and addressed. I am concerned that my failure may be part of a larger, known problem involving GM's 9T65 9-speed automatic transmission. GM has previously issued technical service information concerning the 9T65 transmission and established a transmission replacement pilot program involving certain vehicles equipped with this transmission. GM also developed additional diagnostic and repair strategies based on transmissions returned through that program. These actions raise concerns regarding the reliability and premature failure of this transmission. I am concerned that a transmission capable of completely failing and causing loss of propulsion represents a potential safety defect that warrants investigation, regardless of whether the vehicle remains under the original factory warranty. I respectfully request that NHTSA investigate transmission failures involving 2018 Chevrolet Traverse vehicles equipped with the 9T65 transmission and determine whether there is a common defect or premature failure pattern. I ask NHTSA to review GM's technical service bulletins, warranty claims, field reports, customer complaints, and previous transmission replacement programs to determine whether additional corrective action or a safety recall is warranted.

ELECTRICAL SYSTEM, POWER TRAIN, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
the vehicle will not register that it is in park, when the engine is turned off a beeping noise reads shift to park - you have to start the engine and shut it off multiple times, or slam the shifter into place to get it register in park. this happens constantly and is starting to get old, and annoying. it is listed as a known problem on the forum group. when the notice to shift into Park is stuck on, the beeping will not stop... Also there is a shudder while driving no matter the speed. They did a transmission service and messed with torque converters but has not done anything. Also will be driving down the road with cruise control and the cruise control with randomly jerk and shut off for no reason. Has happened on the interstate.

Car recently started to jolt when accelerating. Noticed it firsthand on the highway while on stop and go traffic. It's been doing it more often now when driving around the city. As soon as you accelerate past 15mph, it starts to jolt. The check engine light is not on. I do see that other 2018 Chevy Traverse have a recall, but my car (when checking by VIN) is not included.

SERVICE BRAKES
On 08/15/26, I was at a traffic light waiting to make a left turn on a major roadway. Because the wait was on a hill, the park brake automatically engaged. When the traffic light turned green and as I attempted to accelerate, the electronic parking brake failed to release as it should and normally does. Since the vehicle would not move normally, I was unable to safely make my intended left turn so I had to continue straight in order to get out of the way of moving traffic. As I was driving to a parking lot of a business in the vicinity, my back tires were screeching and smoking as the park brake appeared to remain engaged. I was extremely concerned because I was in active traffic and could not operate the vehicle normally. I attempted to resolve the problem by turning the vehicle off, allowing it to sit for a few minutes and restarting it. After at least 20 tries, I could feel the pressure of the brakes release and I was finally able to move the vehicle normally. This was frightening and placed me and other motorists at risk. I was stopped at a major intersection on a hill when the vehicle failed to operate normally as traffic began moving. Had the parking brake remained engaged, I could have been stranded in moving traffic or potentially involved in a collision. I have experienced this parking-brake problem at least seven times, including this incident, since I have owned this vehicle since 2017. I have also experienced an abnormal condition involving the vehicle in which it would not allow me to shut off the engine when the park brake was engaged therefore wearing out the battery and I had to have it towed to the dealer. I am concerned that there may be an underlying electrical or electronic control-system defect. This greatly concerns me and it should be very alarming to the manufacturer. I have asked the dealer and called Chevrolet HQ to inquire about a recall or at least recoup some of the money I am constantly paying out of pocket.

Car wouldn’t move in Reverse, I’d give it gas and it would just rev. It would drive forward but very sluggish. Brought to 2 different mechanics and they both said I need to replace the transmission. Car has 97,500 miles on it. This is a known issue with these vehicles. The transmission ship had another traverse and a GMC Acadia in it for the same exact issue.

Vehicle shudders when driving between 18mph and 40mph. Brought into dealership, was told that the Torque Converter is coming apart, and that it would require an entire Transmission replacement. This vehicle has been immaculately maintained, and only has 34745 miles on it. There is no reason that a main component of a powertrain should fail at such a low milage. I was told that the Warranty only convers the part for 5 years regardless of the low milage. Was quoted $8500 (at a discount) for the repair required to make the vehicle road worthy. Just to be clear, this is a one owner, garage kept vehicle that averaged less than 5000 miles a year, with a flawless service record. This is 100% a manufacturing issue.

ELECTRICAL SYSTEM, UNKNOWN OR OTHER
2018 Chevy Traverse purchased from Carvana caused carbon monoxide exposure to my family in military housing. Vehicle locked itself while running in the garage (garage door open), and CO entered the home where my children were standing near the interior door. Fire dept forced entry into the vehicle and cleared the home. All family members required oxygen at the hospital; all 3 children had elevated COHb levels. Mechanic confirmed catalytic converter failure and exhaust defect. Full Description: On 6/7/26, our Traverse turned on and locked itself while running in our garage (door open) as we were preparing to leave. Exhaust was blowing toward the interior door of our military home, and CO entered the house. My children were inside near that door and became exposed. We could not unlock or shut off the vehicle. Fire dept forced entry, confirmed high CO levels, and cleared the home. At the hospital, all of us required oxygen; all 3 children had elevated COHb. A mechanic later confirmed catalytic converter failure, exhaust defect, P0171, and incomplete catalyst monitor—stating this can cause ongoing CO exposure. A Build Verification sheet found in the glove box (not disclosed at sale) showed pre‑existing issues: exhaust rattle, check engine light, and multiple mechanical reworks. Carvana refuses to assist. This vehicle is unsafe to drive or idle.
