2018 Chevrolet Traverse complaints

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.

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 w

I am experiencing and "Shift to Park" notification on my dashboard when my vehicle is in park. This causes my vehicle to stay in accessory mode where ally electrical stays on when I am attempting to turn the vehicle off. Due to the inability of fully turning the car off, my car battery can potential drain out. I have experienced the issue for up to 30 minutes before the notification clears. This is an intermittent issue and comes and goes every few months. When I take it in for service, I'm told the issue can not be recreated and I am stuck with no resolution.

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

The Chevy suffers from the "Shift to Park" issue due to a faulty park switch in the shifter assembly, which is an electrical issue. Apparently GM does not cover this repair but it is dangerous as the car does not shut off even when engine is off and the gear is in park.

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

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.

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.

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.

Transmission issues since 85k miles, park to shift sensor error since owned, rear ideoendent suspension bolts were stripped needed alignment. Car has not performed since ownership.

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.

Shift to park sensor refusing to acknowledge that car is in park and will not allow car shut off

My vehicle has had the issue of putting the car in park and it says it is not it park, have to wiggle the gear shift around for it to recognize that the car is fully in park. Now the transmission will not go in to reverse. The R on the dashboard is blinking. Yes, it is available for inspection.

Shift to park errors over multiple years, shutter when accelerating. Now pressure control solenoid code vehicle will not go in reverse or shift out of first gear. Transmission needs replacement. This is my family vehicle, i have 3 small children and it has turned off at stop lights etc. My families safety has been jeopardized many times driving this vehicle, especially the last time in particular. The vehicle stopped engaging in reverse and then in first would accelarate by itself on the way home from my 8 year olds baseball game.

I am unable to shift the car into park in order to turn off the engine. I constantly reverse and drive again to try again and again until it stays in park or the sensor realizes it is in park and turn off the engine.

I am getting a shift to park error code on dashboard. The shifter gear is in park but the vehicle will not turn off. I have called the dealer several times and they are told the problem but eventually they hang up on me. There seems to be a class action suit out for the issue but no recall. I would like to see recall because this is a serious safety issue. One if the vehicle does not completely turn off and you are not aware of the issue then your battery can run out. If you are in a urban/remote area which I am no dealerships for about 50 miles away can be a serious problem being stranded on the I 15 freeway. When you put the vehicle in park sometimes it pops out of gear too. There were no previous warnings prior to the shift to park dash indicator. I am not a rich person. My vehicle just has over 72,000 miles. This should be covered by a recall. Please help.

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

Light is telling me Shift To Park, this is third time it has happened, first time 2022, second time 2023 or 2024 and now 2025

Exhaust weld broken (several times) same as “special coverage adjustment n212356540 front exhaust pipe”. This is a well known problem but gm refuses to fix 2018s which has the same exact problem and components. Chevy “fixed” it once and the weld broke a month later. This problem has been happening on and off for years and I am finally writing to you so that the word gets out. Gm is taking advantage of people

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.

The contact owns a 2018 Chevrolet Traverse. The contact stated that while in park, there was an alarm beeping. The message “Shift to Park” was displayed. Additionally, the TPMS warning light was illuminated. The vehicle was taken to an independent mechanic who was unable to duplicate the failure. The local dealer was not contacted. The vehicle was diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 121,000.

Vibrations/shaking when driving. Took vehicle to a mechanic and the entire transmission needs to be replaced. I researched online and this is a common issue for the 2018 model. There where several transmission related recalls but my vehicle was not included in any of the recalls.

For the past few months now my 2018 Chevy Traverse has had a weird shimmy when changing lower gears. Got it looked at and they said one of the 9 clutches are going out and needs to be replaced for a total of $6664.63. After doing my own research, this is a common problem with the 2018 Chevy Traverse after reading all the complaints on Social Media and a few Chevy enthusiasts websites. I’ve called the dealership and they refuse to help out at all with the pricing or do anything without a recall issued. If I’d had to calculate the amount of cars effected that already had work done and cars that haven’t had work done yet due to the insane cost, I’d say at least 30-40% of these vehicles have these issues right now that people know about or have already had fixed. The transmission place I sent our vehicle to said he does work on all these Chevys constantly with the same issue. I tried to call corporate and they gave me this site to go ahead and log a safety concern about this problem because it truly is a safety concern. The constant shim and rough feel when switching between lower gears makes it difficult when needing to pull out into traffic unless your lucky enough to get no traffic in your lane. I’ve also noted the start stop problem when it starts back up at a red light it sometimes has issues shifting in between 2nd, 3rd, & 4th gear like it doesn’t want to do it in that order. Feels more like it wants to skip 2nd and 3rd gear which may be fine but it definitely has a shimmy/

The contact owns a 2018 Chevrolet Traverse. The contact stated that while operating the vehicle, the check engine warning light remained illuminated, and the vehicle hesitated while accelerating. Additionally, the vehicle failed to immediately restart after refueling. The vehicle was taken to the local dealer, who diagnosed and determined that the purge valve was faulty and needed to be replaced. The vehicle was not yet repaired. The contact stated that the purge valve was replaced on two previous occasions. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 55,000.

When I put my car in park and turn the vehicle off I get a warning that says shift to park. This has happened before and I have had it fixed a couple years ago. This problem has been ongoing for a couple months. It is not covered under warranty. I have to either start the car again and take the car out of park and then place it in park and then turn the car off, or push up on the gear shift to get the car to recognize that it is in park.

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

Electrical codes saying power steering failure which could cause loss of control of vehicle catalytic converter failure - leading to oxygen sensor failure and burnt spark plugs. engine sputters. If you look online its non-stop reports of this same year having the same issues of catalytic converter failures. health concern, emissions concern, safety concern. GM needs to recall and replace these

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.

My 2018 Chevy traverse has a shift to park warning that continues to come on. It makes the vehicle not lock or park and you have to wait till it goes off. Sometimes it takes restarting the car and turning it off again before it will turn off. this seems to be a known problem when you look it up that 2018-2019 traverse are experiencing this. This should be a national recall for those years specifically.

The vehicle was struggling to pick up the gears and stalled in the road. After having it checked at the Chevy dealer stated it was the Transmission that needed to be replaced. The vehicle is unable to reverse due the the transmission issue. Unable to drive. There is no active recall for this issue which is concerning, considering I've read multiple drivers have the same issue with the 2018 Chevy traverse.

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.

The contact owns a 2018 Chevrolet Traverse. The contact stated that the "Shift to Park" message was displayed. The message was displayed after shifting into park(P). The vehicle was taken to a dealer to be diagnosed; however, the dealer was unable to determine the cause of the failure. However, the dealer informed the contact that the issue was a known issue, requiring that the wiring harness and shifter needed to be replaced. There was no diagnostic code was detected on the OnStar App. The failure occurred intermittently, but during the most recent failure, the vehicle continued to roll after being shifted into park(P). The contact quickly shifted into reverse and engaged the parking brake, and the vehicle lost power without being turned off. The vehicle became inoperable and could not be unlocked. The vehicle was towed to the dealer for additional examination. The manufacturer was not informed about the failure. The failure mileage was unknown.

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.

Each time I drive the vehicle, the transmission has a shudder to where it almost stops pulling. To me, this could cause an accident due to it failing when in heavy traffic. These transmission issues on these vehicles need to be recalled and corrected before someone gets hurt or possibly killed.

The contact owns a 2018 Chevrolet Traverse. The contact stated that while driving at 30 MPH, the battery warning light and power steering assist warning light illuminated. The steering wheel seized, and the vehicle stalled and failed to restart. The vehicle was towed to the dealer, where it was diagnosed with battery failure. The vehicle was repaired.

Exhaust raddling

I’ve had this vehicle for about a year or less the car ran fine with minor problems that come with having a vehicle. Up until last week the car never showed any signs of a failing transmission, it went from running fine to shuttering and suddenly I wasn’t able to reverse. The check engine light never came on, I’ve did all my routine checks and more with the dealership I bought it from and was never told anything when the vehicle was brought in for inspections.

Vehicle displays Shift to Park message and audible tone after arriving at destination and attempting to turn off vehicle. Shifter indicates the vehicle is in Park and the transmission gears display on main screen also indicates the vehicle is in Park; however the warning message and audible continue to occur. Numerous attempts to move shifter through the different positions P-D1 are required to get the warning message to clear and the audible tone to stop. It has rapidly gotten worse in a matter of two weeks and I’m concerned that it will continue to get worse until I am no longer able to clear it leading to a dead battery, as well as other potential powertrain problems. A recent class action settlement unfortunately does not provide any relief to me for this known safety issue which already has a large number of NHTSA complaints filed pertaining to this powertrain issue. Given the number of complaints filed, I would urge NHTSA to force GM to issue a recall for this safety issue.

When my car is shift into Park and I tried to turn it off it’s giving me a “Shift to Park” message and the car continue to idle when it is turned off. I changed gears to try and take it off Park and then put back into Park and the same message occurs and it would not turn off car. After multiple attempts it finally turned it off. This has become more and more frequent. I cannot leave the car if it is not properly in park, still running with the warning bell beeping.

The transmission is slipping which caused the converter to go out in the transmission.

Frequent symptom is an "Action Required: Shift to Park" message on the dashboard. Which is preventing my vehicle from shutting down properly, and causing the battery to drain, and hinder my car's ability to start in addition to getting trapped in the vehicle because the vehicles fail to shift to the ‘Park’ position preventing me from being able to exit the vehicle. This is a known issue affecting various GM models which one being my 2018 traverse by GM but not willing to make official recall of the issue. There is a class action settlement due to this issue that was not privileged to me as an owner of a used vehicle included in this notice and have.

When car is parked and tried to turn off it’s giving me a “shift to park” and it won’t turn off the car. I changed gears to try and take it off park and then put back in park and same message and it would not turn off car. After multiple attempts it finally turned it off.

My 2018 Chevrolet Traverse, has unresolved safety defects that endanger occupants and other road users. These include transmission failure with loss of acceleration, “Shift‑to‑Park” malfunctions preventing engine shut‑off, inoperative blind‑spot/cross‑traffic sensors, faulty tire pressure monitoring, and an active oil leak from the timing gasket cover. These issues occur unpredictably during normal driving and parking, creating an immediate risk of collision, roll‑away, or engine fire. All of these issued happened within a very short time frame. June 2025 and I took my car into Crews Chevy, they want over $15,000 to repair. All of these items I have mentioned have numerous class action lawsuits (that they have won) for the year of my vehicle. I have spoken with GM (and have a case number) however, they are unwilling to repair, at no cost to me. I have an [XXX] daughter and work 7 days a week. I have been with out a car since [XXX] due to these issues. I do have the estimate for the repairs if needed. I do not have an actual repair invoice, as I wasn't able to afford the over $15,000 repairs. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2018 Chevrolet Traverse. The contact stated that while attempting to park the vehicle, the gear shift selector was shifted to park(P), and the message "Shift to Park" was displayed, and the contact was unable to turn off the vehicle. The contact stated that after shifting to park several times, the failure self-corrected. The contact stated that the failure was intermittent. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure, but no assistance was offered. The contact indicated that the vehicle had previously been repaired for the same failure. No further information was available. The failure mileage was 84,000.

The vehicle has a design flaw which causes a bracket which connects the 2 pipes which connect to the catalytic converter to fail. Once the bracket has failed, the rear catalytic converter is allowed to vibrate more than designed, adding extra stress to the catalytic converter. Over time, this additional stress causes the catalytic converter to fail, releasing harmful gases directly from the engine exhaust manifold with carbon monoxide and other harmful gases into the air and into the passenger compartment of the vehicle. This is a know issue that GM has recalled on the 2019 (recall N212356540) and 2021 (recall N222385510) model year Traverse. Other years may have also been recalled that I am not aware of. For some reason, GM has neglected to take ownership of this issue on the 2018 Traverse which shares the same design as both the 2019 and 2021 model years. I have gone to the dealership and contact Chevrolet's customer service multiple times and they refuse to reimburse me for the cost of the necessary repairs. I have already purchased the broken and necessary, ancillary components and repaired the vehicle myself because I did not want to pay the dealership over $2000 in labor which they quoted me.

The contact owns a 2018 Chevrolet Traverse. The contact stated while driving at various speeds, there was a rattling and squeaking sound coming from underneath the vehicle. The vehicle was taken to the local mechanic, who informed the contact that the exhaust manifold bracket had failed and needed to be replaced along with a section of the exhaust system. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure and informed that the vehicle was not covered under the manufacturer's extended coverage related to the failure. The failure mileage was 55,000.

Been receiving a "shift to park" warning message since last year. It seems to be a known issue, however nothing has been done about it. I've had trouble from time to time getting the car to recognize the Park position I've put the shifter in and occasionally have sat in my car with it on for minutes attempting what I can think of to have to car finally recognize that I shifted into Park. I had called a Chevy dealership near me who advised because my car is outside warranty it would not be a covered repair. I'm concerned as I have 2 young children and this is our family vehicle. I cannot leave a car running while I have my children inside or with them inside and me outside trying to turn the car off.

My transmission failed and had to be replaced for 10,000. The car is a 2018 so this was totally unexpected
