2018 Chevrolet Traverse

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.

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.

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.

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.

Shift to Park error occurs 90% of the time I put my car into park. The car turns off but none of the electrical does, like its in accessory mode. Dings when you try to leave the car and will not lock. Display reads 'Shift into Park'. I have to jiggle the shifter to get it to engage. Could be a couple jiggles or 5 mins of jiggling and restarting the car, shifting from drive to park over and over.. This has been "repaired" once under warranty. Now that it is out of warranty the manufacturer refuses to cover any of the expenses on this known issue with a bulletin per your website. I did not realize this was happening to so many. Should be a recall for sure! VERY FRUSTERATING.

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 contact owns a 2018 Chevrolet Traverse. The contact stated that while at a complete stop and attempting to come out of auto stop, the vehicle would not automatically restart. The contact stated that once the vehicle restarted the vehicle hesitated. The contact stated while the vehicle was stopped at a stop light the vehicle drifted backwards and stalled. The contact also stated while attempting to start the vehicle, the vehicle failed start. The contact stated that the vehicle made an abnormal sound as if the engine was about to stall. The contact was able to restart the vehicle after several attempts and had the vehicle jumpstarted. The contact then continued to drive, and once stopped again at a stop light the vehicle stalled and would not restart. The contact had the vehicle towed to a dealer who diagnosed and replaced the alternator. The contact stated following the alternator repair, the "Battery Charging System Service" message was displayed. The contact stated after clearing the message the "Battery Saver Mode" alert was displayed. The contact took the vehicle to the dealer and diagnosed it with a battery and an unknown sensor failure. The battery and the sensors were replaced; however, the failure persisted. The manufacturer was made aware of the failure and advised the contact to reach out to the States Attorney General and contact the NHTSA Hotline. The vehicle was not repaired. The failure mileage was approximately 149,000.

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
