Good Afternoon All,
I have read probably all of the threads here pertaining to BCM issues, and I believe that is what I am facing. There is a ton of really good information here and I have learned a lot. I figured I would throw out a post. I am now dealing with the service department at the dealership and maybe I'm the crazy one. Here is the situation.
2019 1500 with a 5.7. 120K miles or so. Located in SE Georgia.
I had a side window retinted on Tuesday and they also tinted my windshield. When I picked up my truck the headlights and taillights were like strobe lights. I also had a couple warning lights, my taillgate showed ajar, the front and rear parking sensors were alarming and the turn signals didn't work. I asked the guy at the tint shop. He said they had the doors open in the shop and thought maybe the battery was low. He suggested I let it run for a while and it would fix the issue. I drove it home, unplugged the battery and let it sit for an hour or so. During this time, I googled the issue and that led me to here and a lot of threads about BCM issues after tinting the windshield. I called the tint shop. He said they were aware that could be an issue, but they used minimal water and a soak rope and have not had an issue before. I reconnected the battery after about an hour and the issue remained. I wiggled the wires to the BCM and found that made more issues occur, so I stopped, disconnected the battery and put a box fan on the driver side floor board to try to dry it out overnight. The next morning I reconnected the battery and the problem was still there. Now the fuel light was flashing and the ABS light was on.
Wednesday morning I had it towed to the dealership. I told them the above story and they said they would check it out. I hadn't heard from them by Thursday afternoon, so I called the service department. They said they were pretty sure the issue was the battery and suggested I replace it to the tune of $460. I am already into them for a $240 diagnostic fee, so I figure $200 more for a battery is what it is. I reiterate that I don't think it is the battery and I want them to look at the ECM.
That brings us to Friday (today). I get a text from the service advisor telling me the battery did not fix the issue. They tell me the flashing headlights are because there is a sun sensor in the windshield and the tint is throwing the sensor off. I tell them that was my first thought, but my truck has the headlight sensor on the dash, the automatic high beams are behind the windshield in the mirror housing. I also tell them I covered the sensor with a towel thinking it would trick it into thinking it was dark out and turning on my headlights, but my lights continued to flash. Service Advisor tells me my truck needs a fuel sensor ($575) but that will be 1-5 days out. I point out all of the other issues (ABS sensor, Doors ajar, parking sensors) and such and ask if their plan is to just replace all of the sensors or could they please check the module that controls all of those sensors. She said she would have the tech check out the BCM and get back to me Monday.
Long story short, am I crazy to think it is the BCM? Also, are all dealerships like this, just throw parts at the problem and people just pay thousands of dollars on repairs? I am almost to the point where I will pay this dealer for their time and get my truck to an unaffiliated dealer about an hour from me.
Thanks in advance, I welcome the thoughts from the knowledge here.
Erik
