When you turn off engine it tells you to shift to park when it is already in park. Then it continues to give you bells there is a problem. My nephews 2018 equinox has started doing the same thing. Since we just put $1400 in A/C and going back in for A/C we will probably park in since our income can not accommodate more repairs. It only has 53,000 miles on it very well taken care of.
Starting on June 1, 2023 (odometer 73,200), when I shift to park my vehicle & then attempt to turn off my vehicle, I receive a warning “ACTION REQUIRED Shift to Park.” I am unable to turn my vehicle off or lock it until I repeatedly jiggle the shifter for it to sense that my vehicle actually is parked.

Starting on June 1, 2023 (odometer 73,200), when I shift to park my vehicle & then attempt to turn off my vehicle, I receive a warning “ACTION REQUIRED Shift to Park.” I am unable to turn my vehicle off or lock it until I repeatedly jiggle the shifter for it to sense that my vehicle actually is parked. This is a know issue with multiple GM vehicles.
My car started making a rattling noise. It took over a month to finally determine it was coming from the exhaust system. When we inspected it to try to fix it, there is a crack and a hole at the exhaust bracket. This is what has caused it to loosen. After doing research on this, it appears this is a known issue and the warranty …

My car started making a rattling noise. It took over a month to finally determine it was coming from the exhaust system. When we inspected it to try to fix it, there is a crack and a hole at the exhaust bracket. This is what has caused it to loosen. After doing research on this, it appears this is a known issue and the warranty was extended for the 2019 but not the 2018 when it is the exact same issue for both. So my vehicle repair for a known issue is now not covered.

I have a 2018 Chevy traverse with less than 30,000 miles and I keep getting a “Shift to Park” message after my car is in park. It prevents me from turning off my car and locking it. Dealership told me it is a common issue. I will have to pay out of pocket in addition to, in order to diagnose, I have to have the issue happening while it is at the dealership. It randomly happens and I can’t go bk and forth to the dealership to fix it.

As a CPST, I am very concerned by the failure that I have witnessed on multiple occasions of the Snuglock mechanism of the Graco Turn2Me to secure the seat. The Snuglock mechanism is supposed to serve as a lockoff for the vehicle seatbelt, so that the seatbelt doesn't have to manually be locked. However, it seems that the Snuglo…

As a CPST, I am very concerned by the failure that I have witnessed on multiple occasions of the Snuglock mechanism of the Graco Turn2Me to secure the seat. The Snuglock mechanism is supposed to serve as a lockoff for the vehicle seatbelt, so that the seatbelt doesn't have to manually be locked. However, it seems that the Snuglock is failing to do so. I first noticed an issue back in October of 2022 when I went to put my rear facing 2yo into the seat and noticed that it was loose/"rocking". Upon taking hold of the seat, I could completely push the seat over, with very minimal force. I chalked it up to a squirming toddler whom was fighting his father to be bucked the previous day. However, since October, I have found that the seat repeatedly becomes loose over time. It is now to the point that I check the seat every single time we get into the car and there has been multiple times I have had to reinstall in the middle of store/restaurant parking lots. At this point, I am reinstalling weekly due to what I believe is a faulty Snuglock. When loose, you can visibly see the slack in the vehicle belt. It's my belief that, over time, the Snuglock is allow the vehicle seatbelt to "slip" causing this slack and, therefore, a very dangerous, unsecure install. As a CPST, I have helped a number of caregivers whom are experiencing the very same issue. I have 2 videos I would love to share: the first showing how loose the install becomes. The second showing the seat after I have reinstalled (testing in the same locations for reference.) Please reach out to me if you would like to view them.

This Traverse is the Redline Edition. Beginning in November 2022, the Right Passenger quarter LED tail Lamp stopped working. it operates the turn signal and stop light. It is unavailable since that time. It is now 6 months I have been operating this vehicle which is unsafe. It is the whole assembly and I cannot replace it with the regular taillamp due to the wiring harness. I was told from Chevrolet to go to the dealer and the dealer tells me that the part has been on National Backorder for months.
