2018 Chevrolet Traverse Electrical System Problems

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.

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.

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

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.

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.

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

Odometer Fraud. The contact purchased a 2018 Chevrolet Traverse. The contact stated that while attempting to register the vehicle, it was discovered that there was a mileage discrepancy. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 35,532 and at the time of registration, it was discovered that the mileage was 36,986.

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.

The contact owns a 2018 Chevrolet Traverse. The contact stated that while the vehicle was parked and shifted to park(P), the shift to park sensor failed to function as intended. The contact stated that the vehicle was parked; however, the shift to park(P) warning light was illuminated. The vehicle was taken to the dealer where it was determined that the shift to park sensor needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and a case was filed. The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 116,479.

I own a 2018 Chevy Traverse and have been experiencing an issue with the stabilizer trak. When my vehicle goes in idle, occasionally I am getting an alert to check the stabilizer trak. I have reached out to several mechanics and they have all stated that this is a common problem with the 2018 and 2019 chevy traverse. This is a safety issue with this vehicle and I’m wondering how there is no recall for it with it being a common issue found. This issue caused issues with controlling our vehicles, will Chevrolet take action.

Had my traverse for two years, second owner. When I received the car, it had to immediately go into the shop as they couldn’t figure out why all sorts of dash lights where coming on. My car was at the dealership for three weeks and ultimately they replaced the chip, stating that was the issue. Two months down the road, I get the shift to park error message starting. Fast forward to 4 months ago when the stability error message starts to intermittently come on and off. 30 days ago I got the first of the service charging system message and the battery saver mode. My car shut itself down while I was doing 55 miles per hour on a back country road. Every lthing locked up and I had to force a turn to get out of traffic. It was determined my battery was good but alternator was bad. Checked fuses just to be safe all were good. Replaced the alternator with a new one. As of today, I am not able to drive my vehicle because of this same issue. This time I went ahead and replaced the battery and nothing has changed. They are saying it’s my alternator AGAIN. How is this possible that all of us 2018 traverse drivers are experiencing the exact same malfunctions in order and now we have to repeatedly replace the alternator? There is no way 1000s more of traverse owners are all buying “bad” alternators. Something is going on with this and these vehicles are not safe to drive. I can’t even trade mine in because my credit is shot. I pay way too much for this car to not be able to reliably and safely transport my kids to and from school.

When putting my car in park and shutting off. My traverse says warning shift to park when I am clearly in park. I cannot lock my doors and horn beeps. It continues to ding with warning!

The contact owns a 2018 Chevrolet Traverse. The contact stated that the driver’s side taillight was blown due to water entering the taillight assembly. While driving approximately 40-45 MPH, the battery failure warning light illuminated. The contact stated that the following day while driving approximately 40-45 MPH, the vehicle lost motive power. The battery warning light remained illuminated along with the check engine warning light. The vehicle was towed to the residence. The vehicle was not taken to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 45,700.

This concerns a defective transmission control (shifter) assembly. The defective shifter assemblies prevent the vehicles from detecting when the driver places the car in “Park.” As a result, the vehicle goes into accessory mode and one cannot shut off or lock the vehicle, the instrument cluster displays a “Shift to Park” message even though the gear shifter is already in “Park,” and the battery drains. Because one cannot reliably turn off their vehicles when reaching their destination, the Defect substantially impairs the vehicles’ ability to provide safe and reliable transportation. Shifter assemblies are not expected replacement or maintenance parts and absent a defect should not require replacement. Nonetheless, GM had knowledge of the defect and GM fails to repair the GM known Defect. Chevrolet service department has confirmed the defect.

when driving my vehicle with the air condition on after about 25 minutes, the audio system completely goes out. no sound from the stereo, the backup camera alert, the blind spot alert, the "clicking" sound from the blinkers, all chimes, everything. The mechanic looked at the car and stated that this is a result of the condensation from the HVAC system entering the Active Noise Cancellation (ANC) module through the module vents. He stated this should have been a recall as it is an extreme safety hazard as it prevents any audio alerts of the blind spot or backup camera warning systems. He states the ANC module should be replaced and a secondary shield should be installed to prevent this in the future. The sound eventually comes back once the condensation dries up but once the Air condition comes back on again shortly all the sounds go out again.

The emergency park brake engaged automatically, and the battery had to be disconnect to reset it. When the vehicle is shifted to park, the dash display says shift to park even though the vehicle has been shifted to park. Have to start and turn off engine, the shift lever back and forth for vehicle display message has been cleared. This has happened more than once

Shift to park. Car won’t turn off and me and kids are stuck in car. 2nd vehicle this has happened to. This is very dangerous as my car is stuck on.

My quarter panel taillight has stopped working due to moisture in the light (no visible breakage on light). This part is on continuous backorder with no ETA of coming back in stock. Dealer has ordered part but will not give a loaner car. GM acknowledged backorder but will not give rental reimbursement. I have three children I am to put in this car that does not have a left turn signal or brake light. I feel unsafe driving this car as I may be rear ended but everyone I talk to says they can't do anything. What am I to do.

So since 8/02/23 when the vehicle had 54,000 miles it began to give electrical problems. I bought the car 01/16/23 it had only 26,000 miles. The service battery charging system light and battery saver mode went on and also the reduced steering light which began to shut the car down I immediately pulled over. Took it to gm dealer they tested battery was dead then charged it checked alternator it failed so they replaced alternator. 7 days later 8/10/23 the car is still running rough idle. Had savi code p0496 evap flow during non purge replaced purge solenoid. The car still the engine slightly was not 100 percent fixed I told them every time it wasn't good. 02/12/24 I took back to dealer engine running rough and every time I put gas it was hesitant the transmission I am assuming check engine light was on code p0496 the gm dealer diagnosised and replaced canister purge solenoid.so 2/28/24 battery saver mode light came on andservice battery charging vehicle stalled out checked alternator failed replaced alternator. 6/25/24 took to another gm dealer and the diagnosised it check engine light was on and told them my car wasn't starting well after I filled my gas and rough engine. Told me to come back 7/03/24 to do evap canister check engine light was on they found evap leak from from evap canister charged me 508 dollars. So I took vehicle from dealer towards hone filled up gas car would not start problem was not fixed called dealer immediately manager said get here before they close I did and manager left but on service guy got the master mechanic to look at it he said it's purge valve the next day they were closed due to 4th of July so was told to take back on 7/5/24 to replace purge solenoid. The gas issue was fixed but now the transmission is worse when I accelerate it stutters bad I been telling both dealers was told they can't look at vehicle unless check engine light was on so 3 faulty purge valves 2 alternators replaced and car stutters worse shift to park light.
