2019 Chevrolet Blazer Electrical System Problems

2019 Chevy Blazer. Car would not turn off the electrical components when parked. Put car in park and walked away and there is a warning note that says, "Shift to Park." But the car was in park. Called Chevy and they know about the issue on the 2019-2023 vehicles. They sent me the Technical Service Bulletin. Back in 2020, the car had the shifting harness and button replaced and we just had to have it replaced again because it is a consistent issue with the vehicle. Except this time, the dealer charged us $668.40 to fix it! It is a known issue by the company and THEY sent me the service bulletin to get it fixed. It should have been covered by Chevy, or, at least a recall should be instituted. The power to the car wouldn't shut off. We were able to jump the car to get it started again.

My car lost power twice in the middle of heavy traffic we could have gotten killed .i was told it was a battery I bought a battery it happened again .The car goes totally black and it locks you in the vehicle you can’t get out I had to call for help scared to death

I am currently receiving a shift to park message displayed while my vehicle has been put in park and after I turn the vehicle off. While the message is displayed, the doors will not lock and a bell will not stop dinging, notifying me of the error. I have to start the vehicle, shift into gear, shift into park, and turn off several times before the error disappears. I have an appointment to have the dealer look at it this week.

The well known Shift to Park issue where the park sensor is off and my vehicle won’t shut off without being able to register it’s in park. Auto garage quoted $600+ to replace the entire shift assembly. There’s a service bulletin out for this issue and the specific 2019 blazer but no recall

coolant temp gauge stuck on cold, AC quits blowing cold air, reads the thermostat code when check engine light comes on. Was told my car needs a new thermostat and a coolant temp sensor. This has proven to be a common issue among Blazers. there is no rhyme or reason when this happens and will fix itself after a while, but then happens again.

35,000 miles and P0128 code that does not resolve after expensive repairs of coolant Temperature sensor and thermostat multiple times.

P0128 error, power steering reduced warning, cooling fans on, no a/c and temp gauge stuck on cold

I bought a 2019 Chevy Blazer in February 2023 . The vehicle has issues when I fill it with gas. As soon as I gas up to full it starts jerking immediately afterwards. It makes loud popping sounds. The engine dies completely. It starts to tremble and will not go. When I try to turn in back on , the starter works very hard before it will turn back on. It does turn back on eventually but I have to pull over to the side and accelerate the engine until it finally stays on. I drives that way turning off at lights and stops. After about 10-15 minutes of this , it finally stays on long enough to drive another 20 minutes or so to get home. After it rests for a few hours, it goes like normal. This is a big safety concern for me since these episodes happen every week when I fill up my car with gas. I have almost been hit from behind during these episodes and it is very scary and such a hassle to have to deal with this every week. I have already had several Chevy dealers and mechanics work on this problem and it continues to act up like this. I have all the paperwork for the work that has been done. $15, 000 have already been spent on this problem and the problem still continues. Please help me. I like chevy vehicles and have always bought chevy but this is the second chevy vehicle that has given me problems when I gas up. Please look into this problem.

When I shift the car into park and turn it off I get a message that it isn’t in park though it is as displayed on the console. To clear the message I have to move the shifter back and forward several times. I’ve had it in the shop twice already but the problem continues to return. This should be a recall!!

When the vehicle is in park and you try to turn it off with the start/stop button an on dash error code of ‘Shift to Park’ appears even though the vehicle is clearly in park. You are not able to turn the vehicle off. This currently is forcing me to restart the engine, put my car in reverse, shift back in drive, try re-parking and turning it off again, repeating the process until it eventually turns off. I do not know if my car is truly in gear or not. I’m afraid that it might cause a dangerous situation. GM has already identified this recall for other VINs of 2019 Chevy Blazers I believe it should be extended to additional VINs.

I recently stopped at a local store and put the car in park. A message appeared on the dash Shift to Park. I was not able to turn the car off and I had to move the gear shift back and forth until the message went off. I couldn't lock the car correctly by moving away from it. I used the key fob to eventually lock the the car. My concern is that if my wife is driving, she may not be able to lock or move the vehicle. This seems very unsafe. Should this be brought to the attention of the local Chevrolet dealer?

Shift into Park warning when turning vehicle off even though vehicle is in park.

With great frequency when I put my 2019 Chevrolet Blazer into park position I receive the error message to "Put vehicle into park" when it is in fact in the Park position after done driving. I've tried putting the car into drive again or reverse then back into park position or trying to turn the car off then back on and this does not clear the message. I am unable to turn the vehicle off completely until the message has cleared. The vehicle remains in Auxiliary mode until the message has cleared which takes several attempts. This is a huge inconvenience!! My local Chevrolet service center has checked my VIN information and there are no active, repaired or expired recalls for my vehicle. This has been a long time issue with this type of vehicle according to the Blazer forum. PLEASE ISSUE RECALL FOR THIS ISSUE ASAP!

1. Wire harness with coil wires is the problem. It was fixed by a local shop and the vehicle can be inspected if needed. 2. The car throws a code for a faulty thermostat/coolant temp sensor. This will not allow the car get to oporating temp and could cause engine damage or not perform properly causing risk of an accident. Also this will reduce the driver assist features such as lane assist and adaptive cruise/braking. 3. Yes. 4. A local shop inspected the thermostat and coolant temp sensor and they oporated as they should. 5. The engine light comes on for the reasons mentioned above. It also has a "driver assist reduced" message. It appeared randomly while driving and stayed on for multiple days. Vehicle had a code for a bad thermostat/coolant temp sensor and "driver assist reduced" message. The cause is NOT the temp sensor or thermostat and is actually a wiring harness that two wires need to be separated from the bunch. The frequency from one wire interferes with the coolant temp sensor wires. I am on several forums for chevy blazers and there are TONS of posts about this issue with the 3.6 V6. Most people will go in and have these expensice parts replaced. It is not acceptable to have people get charged for a $800+ job when the part is not faulty.

When placing the vehicle in the park position and attempting to shut the vehicle off with the push button my DIC flashes a message stating to 'shift vehicle into park'. I have to move the shifter from park to another gear several times in order to keep this from appearing and allowing me to turn my vehicle off. I can take up to 5-6 times before I can get the vehicle to allow me to turn it off. I'm not really sure if it is or isn't in park even when I do this at that point. I have had this happen on multiple occasions over multiple months.

My 2019 Blazer won't shut off the electrical system because of a "shift to park" error. This causes a drain to the battery and could leave me stranded. The problem is simple electrical switch that is not making the connection to tell the car to shut off. This is a well documented problem with chevy vehicles in the late 2010s and includes multiple models. I have not had the problem verified by a Chevrolet dealer. I've reviewed multipe youtube videos that has had 10s of thousands of views which demonstrates the problem is very wide spread. Why is this not being recalled?

I placed the shifter into the park position & a warning came on the dash stating the car is not in park as I turned off the ignition. The warning on the dash as well as an audible warning. I had to use the key fob to lock the doors. I took the car to the dealership for repairs.

When parking gear is in park but when turning car off car is saying gear is not in park.Turning car back on gear says in park but when turning back off still says shift to park and then you have to willing gear to see what’s going on. If gear is saying in park but actually not in park it can damage to car & people unknowingly

While using my vehicle, twice in one day, my vehicle failed to recognize that it was in park. My 2019 Chevrolet Blazer essentially malfunctioned, and was unable to recognize that it was in park, which left me unable to leave the car to go into my office building. The car was in fact in park, but did not recognize this fact. I tried exiting the vehicle and closing the door, but the car still would not turn off. I was left to essentially babysit my car, while attempting to work the gear shifter back and forth between drive, reverse, and park, until it eventually finally accepted that it was set to park, and allowed me to fully power the car down. If I am unable to have the car recognize that it is in park, I am unable to leave it, as it can be started and driven without the FOB due to the potential safety hazard of the vehicle thinking it is not properly shifted into park. The battery will also be drained, effectively leaving me with an inoperable vehicle. In the image I attached, please view the bottom right corner of the dashboard which indicates "P" for park, while the vehicle still states that I am not shifted into park. I have a video of this incident, and it appears many consumers with select models of Chevrolet and GMC cars also have this issue. I find it appalling that many have already discovered this issue, yet no recall has been placed to fix this widely known issue (even by GM according to their bulleting regarding this).

I have a 2019 Chevy Blazer RS with 12,350 miles on it. As you can tell I use it locally. A month ago I pulled into my garage, put the car into park, shut the car off & a warning came across the dash saying "Shift to Park". I started the car back up, put the car in neutral then park & shut it off. The message was gone so I blamed it on something I must have done. Two weeks later the same thing happened. I did the same routine and it fixed itself. This time I started taking notice. Last week it did it again. Today was the worse. I was at the grocery store and it took 3-5 minutes to fix it. I already have an appointment at the dealership on 3/20/24 for an oil change, tire rotation & 12-point check up. I'll be bringing this malfunction to their attention. I'll also be bringing a credit card with me because I have a feeling after doing some investigation that I might be getting [XXX] in the pocket book. I see some places say it takes an hour and costs a couple hundred & others are charging $500 & keeping the car over night. I also see GM has known about this since 2016 with the Malibu and Volt. How sad a recall hasn't been ordered for this issue. I've read it could be a $9 wire harness that can be bought at GM Parts Direct. So GM doing nothing over a possible $9 part? That's a sin! The constant chiming wears the battery down not to mention being the only person in the car who knows nothing about mechanics is a scary position to be put in. I saw 3 class action law suits have been filed so isn't it time for the Federal Government to step in and do something about this? It's absolutely absurd to allow this to continue now going on 9 years. I can't buy a winning lottery ticket, but boy if there's a faulty product out there I'll buy that. What are the chances of me, after fighting to finally getting an SUV for decades, I finally get the only Chevy in 2019 to end up with a problem GM won't acknowledge.
