2017 GMC Acadia

I get a "service side detection" on my DIC. It used to work occasionally, now it no longer works. The sensors lights do come on when the "service side detection" shows up. Sometimes this alerts comes and goes and sometimes it stays until I push a button, in which it just reappears later. Through research I found this document sent out from GM: https://static.nhtsa.gov/odi/tsbs/2019/MC-10160088-9999.pdf GLOBAL SAFETY FIELD INVESTIGATIONS DCS5011 URGENT - DISTRIBUTE IMMEDIATELY Subject: N172097060 - Special Coverage Side Blind Zone Alert Module Water Intrusion General Motors is releasing Special Coverage N172097060 today. The total number of U.S. vehicles involved is approximately 131,652. Please see the attached bulletin for details. Condition: Some 2013-2016 model year Chevrolet Cruze, 2014-2015 Chevrolet Impala and 2013-2017 GMC Acadia vehicles, may have a condition where the Side Blind Zone Alert (SBZA) modules may fail or malfunction due to water intrusion. The driver may experience a side blind zone alert message displayed on the driver instrument cluster (DIC). If this message is ignored, the condition could result in the corruption of LS GMLAN that may result in the loss of some driver interface functions such as cluster, infotainment / displays, chime, and passenger presence detection (passenger airbag could be suppressed, w/airbag TT, DIC message). MAJOR SAFETY CONCERN!! Special Coverage Adjustment: This special coverage covers the condition described above for a period of 6 years or 80,000 miles (130,000 km) whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership. CORRECTION: Dealers are to repair the vehicle by ordering and installing the appropriate service kit. The service kit will contain all of the components required to complete the repair. The repairs will be made at no charge to the customer. PROBLEM: MY CAR HAS A BRANDED TITLE SO THEY WILL NOT FIX IT. IF IT IS A RECALL, THEY HAVE TO.

The "shift into park" when car is in park. U have to click the gear shifter several times for ut to turn off. Sometimes even having to put the car back into gear putting it back into park and the error will come up again. By clicking the gear shifter will shut it off. Sometimes this could take 2 minutes playing around with it sometimes 10 minutes sometimes it doesn't do it at all. I finally replaced the entire gear shifter mechanism by taking the center council apart. Labor price was unreal. Part price wasn't bad.

I put the car in park and the push button start would not let me turn off my car. I sat in the parking lot almost 30 min, putting my car in park, then drive, then park for my car to recognize its actually in park to turn off. I started getting this error on the start and stop at lights... it never turned off during the start and stop but fearing my life or my families life.... I took it to my local GMC dealership and the manager from the Service department said this is a common issue with this model, he has repaired HUNDREDS of them. His words. This is a safety issue.... I am shocked this has not been recalled. The lack of urgency to get this fixed is very concerning. It costs my $708.92 to fix this issue. I 100% think i am owed this money due to something that should 100% be recalled. I found an open class action lawsuit that was confirmed by the dealership to be the exact same issue I had. https://topclassactions.com/lawsuit-settlements/consumer-products/auto-news/gmc-class-action-alleges-acadia-shift-to-park-defect/

1. COULD NOT PUT CAR INTO PARK OR TURN OFF. CAUSED BATTERY TO BE DEAD AS IT WOULD NOT TURN OFF WHEN PUT INTO PARK. 2. STEERING WHEEL LOCKED AND JERKED REPEATEDLY. COULD NOT TURN INTO PARKING SPOT. THE STEERING WHEEL HAD A MIND OF ITS OWN AND COULD NOT STOP THE JERK. IT IS DANGEROUS AND SCARY ! 3. AT NIGHT, THE HEADLIGHTS DO NOT LIGHT THE ROAD. IT IS AS THOUGH THERE ARE NO LIGHTS AT ALL. IT IS DANGEROUS TO NOT SEE THE ROAD AT NIGHT BECAUSE HEADLIGHTS DO NOT GIVE APPROPRIATE LIGHTING.

GM put out notice in April 2019 stating side blind zone alert message due to water intrusion May cause issue with driver interface functions. Do not take your vehicle to dealership unless you believe there is a problem. Reimbursement by 4/30/2020 6 years 80,000 miles. Vehicle stopped working while parked in driveway. No start, no cranking, warning lights for security lock out, side crash detection, tire monitoring service and airbags displayed. Dome light for front door did not work while second row lights did work. Lift gate would not open. When stating issues to dealer prior to service were told they had not heard of anything that would stop a cars engine from functioning. Dealership repair stated this was due to rear blind side detection module and that the module shorted out cause all other circuits to go to ground, yet no fuses were blown. Starter fuse and relays were good. I asked dealer if this could have caused my car to stop while driving and they answered yes. Have corroded module and wire loom referee to as kit. Was told no way to circumvent system other than replacement.

Shift to park error code along with several other error codes including no remote detected that have continually and intermittentantly appeared since my car was at 16 K miles. My car has been in the shop over 10 times and these problems continue to return. my car won't shut off correctly, and this drains the battery. On 2 different occasions I was locked inside my car, unable to start it. Both of those times the outside temperature was over 100 degrees, and I almost had to break my window to exit and survive. I frantically pushed several buttons, trying to start the car, and luckily something tripped so I could open my car. The dealership replaced my battery twice before 31 K miles. They have replaced 2 different fobs when the car didn't recognize them. The dealership has replaced the transmission control assembly, the body control module, the fuel injector, the immobolizer control module, the brake control module, and my car has currently been in the shop for over 3 weeks as they may also need to replace the instrument control module and HVAC module due to those error codes. My car is at 46 K miles and has been in the shop 3 different times since 39 K (less than 10 K miles) all for similar problems. Thankfully I bought the extended warranty that will expire in 2 years. Something is draining the battery and GMC cannot or will not address the problem. There are similar documented cases: https://lemonlawexperts.com/gm-shift-to-park-recall-update/#:~:text=According%20to%20NHTSA%2C%20GM%20has,several%20model%20year%20Acadia%20vehicles. and https://gmauthority.com/blog/2020/05/gmc-acadia-shift-to-park-class-action-lawsuit-filed-in-texas/ Please help to make GMC resolve this complicated problem! I now keep a tool in my car to break a window if I ever get locked in. I also keep my AAA membership active as I have had to get my car jumped several times. I do have videos of the problem, but cannot send a MP4 file.

P0128 Apparently what happens when the temp sensor on the T-Stat housing goes bad it sends a signal to the ECM that the engine is overheating, causes the temp gauge to peg to "C", shuts down A/C Compressor Clutch engagement to not exacerbate the Overheat condition and super speeds the cooling fans. Of course it's a false flag warning and the engine isn't actually running hot. At the same time a signal to the ECM also tells the Power Steering Rack that it's Super Cold out and the lube in the steering system may freeze up causing loss of steering assist. NHTSA 17-NA-158 - MAY 2017 Needed to have Thermostat and Temperature sensor replaced. Was quoted by two dealers $1400-$1700. Very deceiving for GM to have SEVERAL "tech bulletins" advising their techs how to properly diagnose this common "error"... but it's not a recall so they won't foot the bill for what is clearly a defect. Car has only 59,400 / 2017 GMC Acadia All Terrain

My vehicle has serious issues that from my research seem to be a common problem/manufacturer defect experienced by other owners of this model. I believe the defect/issue is an electrical problem. While driving, the vehicle will often have problems using it's automatic transmission. It ranges from "rough" shifting (where the car jerks while shifting gears) to situation where the vehicle fails to shift gears completely leading to the RPMs shooting up. The cars power steering and traction control system also simultaneously fail. This leads to a dangerous situation when on highways etc This issue simultaneously causes all of the warning lights on the dashboard to light up while displaying the following messages on screen "Service stabilitrak" & "steering assist reduced -drive with care" & "service brake assist" & "service parking brake". The gauges also stop responding/reflecting accurate info when this happens. I have a video of what this all looks like. This has been on ongoing intermittent problem pretty much for the entire life of the vehicle. GMC informed me that they had never heard of this when I inquired about it a dealership but searching online makes it incredibly clear that this is an extremely widespread issue that they are aware of. I have also attached a file that has a list of all error codes detected by me for this vehicle.
