2018 Chevrolet Traverse

Exhaust weld break similar to the 2019 Chevy traverse

The contact owns a 2018 Chevrolet Traverse. The contact stated that upon parking and attempting to turn off the vehicle, the message "Shift to Park" was displayed while the gear shifter was already in park(P). The contact stated that the vehicle responded after several attempts to shift to park(P). The dealer and the manufacturer were not contacted. The vehicle was not diagnosed or repaired. The failure mileage was approximately 81,000.

When car is shifted into park, it does not register that. It is in park. Therefore the car keeps beeping, and you cannot leave the car in this position. This is the second time that we have had to address this problem once in 2021 and now in 2026 I believe that General motors should fix this problem without the consumer being charged to have it corrected.

The vacuum pump had a catastrophic failure. This led to failure of assisted breaking, and caused brake pedal to go rock hard while driving on the roadway. Metal shards from the vacuum pump broke off, and has now entered the engine. Chevy knows this vacuum pump is flawed, but did not include my model of vehicle in the recall. Even though it uses the same part. I received a “brake assist” message on the dash about 15 seconds prior to the loss of brakes. I had my wife and two kids with me, and this jeopardized their safety. Further research on the matter states this is a known issue at GM, but for some reason my year and model were not included.

The exhaust system on my 2018 Chevrolet Traverse has failed due to cracking in the exhaust pipe and/or muffler assembly. This appears to be consistent with known issues in similar model years where exhaust pipe brackets separate and cause cracks or holes in the exhaust system. The failure has resulted in excessive exhaust noise and potential exhaust leakage. The dealership has confirmed the issue and recommended repairs costing several thousand dollars but stated my VIN is not included in the existing recall or special coverage. Yes, the vehicle and failed components are available for inspection upon request. The failure of the exhaust system creates a risk of exhaust gases, including carbon monoxide, entering the passenger cabin, which poses a serious health hazard. Additionally, a compromised exhaust system can affect vehicle performance and emissions, and in some cases may increase the risk of fire if hot exhaust gases escape in unintended areas. This issue is especially concerning because it has been identified in other model years of the same vehicle, yet my vehicle is not currently covered, despite experiencing the same failure. This creates an ongoing safety concern for myself, my passengers, and others on the road. The problem been reproduced and confirmed by a certified Chevy dealer.

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.

Shift to Park" Error.. even after turning the car back on.. slowly going through each gear and back down to park I'm still getting this error

My car has been acting odd and shaking a lot. Was told it could be transmission since i fixed everything else it could be

When putting the vehicle in park it doesn’t recognize it’s in park and keeps saying shift to park.

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.

Hello this particular vehicle often gives us a message stating that side detection is temporarily unavailable and the main issue is the transmission seems to have severe shufdering issues and sometimes gives a shift to park message ive read others having this same issue being recalled but my vin is not listed! The car is available upon request for any inspections necessary

Vehicle was driving fine in good condition and well maintenance. No warning at all and went to drive it home from a friends and it would not go in reverse at all. Towed to dealership and they said it’s a transmission issue. There is a recall on 2018 chevy traverse vehicles. My vehicle is not showing up but I do believe this could be the issue and should be considered a recall

The contact owns a 2018 Chevrolet Traverse. The contact stated that while driving at 25 MPH, there were exhaust fumes entering the cabin of the vehicle. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, and the mechanic was notified of a failure with the exhaust manifold. The local dealer was contacted and informed that there was no warranty coverage on the vehicle for the failure. The vehicle was diagnosed, and it was determined that the exhaust manifold weld needed to be re-welded. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The contact was referred to the NHTSA Hotline for assistance. The failure mileage was approximately 98,000.

I have had this car seat a little over a year and the chest buckle randomly stopped magnetizing. It will appear magnetized but will pop apart. This is absolutely unsafe and these seats need pulled from the consumers.

Noxious emissions fill passenger compartment while at idle, or when using remote start. Cannot drive with windows closed, or with recirculation on. Passengers feel, "sleepy". Bracket holding flex pipe fails at the same point in several different traverse vehicles. The 2018 model we have, is not covered by a recall, even though the 2019 of the same design and fail point, is. N222385510 GM is addressing this on only select models, even though the same issue is applicable to other models, and the same part numbers are the cause and or affected.

The shift to park started popping up randomly for a month now does it every time I try to turn my car off. I have to wiggle, push the button and more times than not I have to turn back on the car and move gears to see if that will help (which it doesn't). Super annoying

Park to shift keeps popping up on dash while driving. Vehicle will not recognise when in park at times to allow vehicle to be shut off properly. The stability track warning pops up on dash now as well. The check emits comes on with codes for all going back to transmission control module system and when replaced spark plugs we found that the PCV (cam cvr to turbo) tube was cracked all the way through where the hard plastic meets metal on the part and had to replace it. This is all after multiple failed parts that had to be replaced dealing with the ac unit and it’s lines. Today is the second time in two weeks that the vehicle has been in operational mode in the middle of a foward motion driving at the time. Luckily this time I was in a housing area and not a major street or on the loop 360 when it decided to stop driving while in motion in drive.

When the gear shift is in the park position, the system does not recognize it so the car doesn’t properly shut down; on occasion draining the battery. The shift to park problem has been present for 4 years. It has not drained the battery until this month.

The car has a "Shift to Park" error message. We noticed a recall for other 2018 Traverse vehicles and wonder why ours is not covered. Car will not shut down completely. Battery is drained. Dealer is requesting $767.43 to repair when other GMC/Chevy vehicles are identified in a recall.

After shifting from drive or other gear to park, vehicle will not register vehicle is in the "park" gear. Vehicle is in the "park" gear and will not move but is not turning off. "Shift to park" is displayed on the display. Vehicle will not shutdown the display system and keeps beeping. The issues worsens over time and continues to drain the battery. The vehicle is kept on.
