Just installed this on our 2018 Malibu premium and it has worked. I saw some other videos out there that describe the problem being at the microswitch which I can believe given my past experience with similar switches on my Chevy truck. I don't know how reliable these things can be over the long term so it doesn't leave me with much confidence in their ability to last very long. As a precaution I bought 2 of the microswitches if this continues to be an issue. The microswitch is hard wired in with solder. Someone posted the part number for those microswitches (653-D2HW-BL221H) on another video. I did a Google search and found them quickly for sale on a few different websites for around $3. Thanks for posting the video it was very helpful.
Thank you so much!! I bought the part and following your instructions did the whole install in less than 20 minutes on a 2019 Malibu..... I replaced your tool to release the connector lock with an earring!! LOL - was curved at just the right angle!! I did not unplug the first two connectors was able to get to the wiring harness connector without doing that!! Great job on the video - problem is solved!!
GM absolutely should be fixing this! I just spent half an hour on the phone with GM Customer Care asking why there isn't a recall for my Camaro because my dealer wants nearly $500 to fix it. She tried to tell me there is no manufacturing error and they have no way of knowing if it was my driving that caused the issue. What BS! How could this many drivers across several different GM models being causing the same issue with their driving habits?!
By the way, the shifter handle has 2 plastic release tabs on the left and right to get the shifter handle off. Just pop them with a hook pick after you peel the faux leather boot all the way up and over the top of the handle knob. I saw some other vids of guys muscling it off, figured there must be an easier way.
I just recently had the same issue on my 2019 Chevrolet Malibu LT with the shift to park. I took it to a Chevrolet Dealership and I was fortunate to get an extended warranty when I first purchased it a few years ago. They replaced the shifter assembly (control) part number #13534328 and installed an in-line jumper (harness) part number #84733196 free of charge. No more issues. Extended warranty makes a huge difference as well. Without the extended warranty, it would have cost me around $574.00 in parts and labor. Great video!
Part is $12.75 and bulletin says .3 hours (18 minutes). They better not charge $574 for that! I'll definitely find out though because I don't want to pull apart the console.
I started getting the same issue last month (just as the warranty ended) and it's getting worse. I saw other videos with other workarounds (fiddling with the shifter) and bending the metal plate that's supposed to press the switch to make it more likely. I'm worried about this happening right before Christmas. On top of that, I got a message from Onstar about the battery being low. I just had it in last month and they didn't say anything about the battery going. I may have to do this myself.
Thanks for the video, I have this problem with my 2016 Malibu and I had seen different "Mickey Mouse" fixes as far as using a paper clip to short the harness, but this is the way to go!!
I finally went to change this in my dad's Malibu and he already had the bypass wire in there. So I just swamped it out with what I had anyway and the message came up but then it went away a few seconds later. If it's still happening I guess the next step is to change the entire piece right?
Follow up on jumper install. It did not fix the problem, i guess will be doing the next step which is to manipulate the little metal strip to push sensor in🤞
I’m going to guess this doesn’t apply to newer Malibus because they will already have the jumper or should have an extended harness. For those, the micro switch is to blame. Interesting to see in the TSB that this applies to the Volt too since my brother had that issue (wrecked it in 2022 tho’).
Does anyone know what’s actually happening here to fix this besides plugging in the jumper wire (the obvious) what’s really going on how’s the problem being fixed how does this wire trick the system??
Just installed said jumper, and now we wait for the results, but initially the shift to park still showed up. Unplugged battery for reset and now we wait
Just performed the repair on a 2016 Malibu Hybrid. Struggled with getting the connector off the wiring harness - but my wife fashioned a 'hook' of galvanized wire which she then used with her smaller hands to depress the connector retainer. Not my favorite design. Seems to be fixed! And only about $13 for the part.
Question on this fix...what is the harness doing, that fixes the problem? I have read the issue with the micro switch isn't the metal tab hitting the button, but that there is over voltage occuring killing the switches. Is this harness the voltage suppressor? I have read that you can change the micro switch with a new one but if you don't install "the voltage suppressor," it can do other damage.
My question the same. What does the "by-pass harness" do? I bent the switch tab didn't help. Grainger has a switch. But if the harness is a so called by-pass. Why could i just by-pass the switch?
Yes, just clip the the metal sensor switch and soder the two wires together and put electrical tape around the end. It by passes the whole problem and is a free fix. Saw it on another youtube. It worked great for my 2018 Malibu hybrid. @@nathank4708
I was trying to bend the metal piece down like I saw in other videos and it ended up falling off completely. Would I need to replace the whole shifter now? Or will this bypass work without that metal piece there?
If this fix doesn't work for you and you cannot get your Volt to turn off, a new connector and wring harness are free as well the install at your nearest Chevy dealer (reference GM Service Bulletin 19-NA-206, dated February 2020). Let me stress that if you cannot get your car to turn off (Chevy Blazer, Malibu, Traverse, Volt, GMC Acadia), you 12 volt battery will run low and be killed if you don't get it to a dealer ASAP. The dealer will not give you a free battery ($200) plus battery test socked me for $234. So if you cannot get it to a dealer, disconnect the 12 volt battery in order to save it. If you get it to a dealer, disconnect the battery when you get there and alert the service department that you did so. GM will reimburse them for the installation of the harness and shifter, not the battery. That's on you. Just figure I'd give you a heads up.
Thank you so much for responding, I did call and my car does have some sort of warranty but they want me to take it for a diagnostic to the dealership and then they’ll see what they can help me with apparently,
@@carltonaustin1311 Carlton, I know I’m late to the party but does the new wiring harness somehow bypass the micro switch that everyone else talks about, fixing by bending the metal tab on the switch back?
It didn't really work for me. I installed it and worked ok for a few days then issue returned. I ended up replacing the micro switch. Left this installed and haven't had an issue since.
@@rmunoz360 so what do you recommend for me I am having this problem and can not start my car bending it doesn’t work and cuttin off the switch and connecting the wires don’t work
Another update: so I had to go to the little lever and bend it a little bit to push the button sensor, in addition i added a small hose on the shifter for assurance, and voila no more shift to park message.
According to the Technical Safety Bulletin the Cause is as follows: The cause of the condition may be that the park switch in the transmission control (shifter) assembly is not pulling the BCM signal low to electronically show that the vehicle is in the Park position.
The harness jumper fixes this condition. Please read the TSB at static.nhtsa.gov/odi/tsbs/2019/MC-10166630-9999.pdf to make sure you follow all the steps. I read it and it looks like GM wants you to clean the Park Switch electrical contacts before installing the jumper. Good luck.
@@danpruteanu9268 yeah I got that. Is it a bypass situation or does the jumper actually rectify the issue? If my issue is I have to keep bending that flimsy arm for the selector to push it up far enough for the button on the micro switch to be pushed will this benefit me?
@@marcusb6666 I adjusted the micro switch and had the same issue within a few days. I have not had the warning since I installed the jumper per the bulletin. Thanks.
@@carltonaustin1311 I ended up installing the harness as well last week and have been driving for a week without any warnings any more. Hope it stays like this. I will update my comments if anything changes. Good luck.

Thanks for doing this video and especially for including the P/N for the harness. Super easy fix and no more Shift to Park message!
Great way to beat the dealer repair ripoff when something breaks. Good video, easy to understand. Can't wait for the detailing videos.
For the 2018, the harness is not the issue. It's the actual switch in the shifter assembly. They need to design a better switch or design.
You can also replace the switch if you know how to solder. The part number for the exact switch is 653-D2HW-BL221H
Thank you for saving me a bunch of money.Im 59 and I always watch Utube videos to see if I can fix my cars symptoms 🙃
Thank you so much. Great help in fixing this problem that GM should be fixing since it is such a common problem and clearly a design flaw.
