Unsafe to drive!!!!

[Lou's Vert]

Soooooo...I'm a new camaro owner. Bought a 2011 camaro convertible about 6 weeks ago. My dream car! I thought??? After two weeks of pure bliss.. It starts!!

1. Start car.. Didn't want to turn over. Then a loud pop. Then service stabili trak light comes on.
2. Driving to work same morning reduce engine power! And service engine light. Before we can get it to dealer we stop by autozone to read code. Can't remember code # but it said bad ECM. Before we could get it to dealer light went off. They couldn't help us with no codes!
3. A week later I crank car to go to work. Display telling me crazy stuff. Roll driver window down then up. Then roll passenger window down then up. Then rear window down then up. So I did it and all seemed ok. 20 minutes later I get to work pull in parking lot all lights on dash again and service stabili trak and car goes dead! Won't crank! Call wrecker have towed to dealer. They said all the codes were saying low voltage. They said we need new battery. So $300 later and we think we're good to go.
4. A day later we take a weekend trip. Car acts fine on the 200 mile drive. We valet park the car and think all is good. Next day valet brings car to us. Immediate we notice the A/C not working. Drive on down the road and it starts again. Light all over the dash and service stabili trak. Barely make it to restaurant car seem to be idling rough and about to die. We stop the car. Shut it off. Open the door. Close the door and windows are acting crazy. Trying to roll it self up but can't. As convertibles do drop and raise windows when doors open and close. Crank the car.. Seems to be ok for now. Try to find dealer open on Sat. With no luck. Decide we are going to cut our trip short and try to get home on a Sat. Maybe better luck to get a wrecker on a Sat.
4. Same day trying to home. Didn't make it far maybe 15 miles. And here we go again.
1- lights start flashing all over dash.
2- door locks on car going crazy!
3- car down shifts on it own..sends RPMs close to red lines and LOCKS UP BACK BRAKES GOING 65 ON THE INTERSTATE!!!!!!! If someone had been behind us. We could have been really hurt!!!! We were not in a safe place to stop so we try to go a little further thinking maybe we could get it to a dealer. Wrong!! Just a little further. And all lights flashing car still going crazy. Time to call a wrecker. 1 hour on the side of the road. A ride in the wrecker to the nearest dealer. 200 miles from home. Can't find a rental car. Have to take a taxi to a hotel. Stay the night. At that time we get in touch Chevrolet concierge and they work out details of rental for the next and pay for our hotel stay. Well at least we had that even if we were stranded!!!!!
5. Car at dealership 200 miles away for a week. Never messes up. No codes of course so nothing they can do. So we have to get it. Which means we have an 8 hour day trying to get the car home!! I was not happy about driving an unsafe car!! We felt sure it was going to happen again!!! My husband drove it. I followed him not to close in case it decided to go crazy again. A very stressful ride to say the least.
6. Same day driving home made it about 3 hours and here we go again!!
1. Starts with door locks going crazy!!
2. Slowing down because it going to happen.. Car down shifts again on its own RPMs going high again but car seems to be in neutral again and is slowing losing power. On a two lane road. Flashers on looking for a spot to get off the road. Car finally dies on its own. Takes a bit to get it to crank again. Finally we try to go on..we about 45 min. from home. Car seems to be doing ok. But seems to have reduced power. And now the A/C is not working again!!!
3. Made it to AutoZone as no dealers are open.
Error codes...1. P2105 TAC control module.
2. P025A fuel pump control / faulty ECM or FPCM
3. P069E FPCM
4. Just made it to dealer with car. Flashing all light and service stabili trak on.

Soooo I know this is a long post and I know I'm new to here but to say the least I'm quite upset!! My car is back at the dealer for the third time in two weeks and I haven't had the car but 6 weeks!! And of course the dealer won't be able to look at it until Mon. So back to one car!!! So frustrating!!! Love the car when it's working but who wants a car that is scary to drive!! Not me!

Any advice from anyone? I'm so sad! Who wants a cool car to drive if your just wondering when your going to be stranded next. I'll give updates. As soon as the dealer looks at it. Let's hope the service engine light is still on! Thanks everyone who takes the time to read.

Sounds like wiring at or near the ECM.

Some others on this forum have had these types of issues and it's been hell to find a tech at the dealer that was good enough to track down the problem.

wiring or a bad module
if the cars tells you to roll down and up the windows that is usually because the battery was disconnected or the BCM was disconnected, so unless you did something like that then your BCM is losing communication with the PCM/ECM.

CANBUS cars always get crazy problems when a single module starts losing communication, it messes with all the others

My first thought is that this car was in a flood or had some other water problem.

Thanks for the response. Sounds like it could be the BCM after reading what it controls.

Since we are new owners to the car we don't know all the history on it. It did have a clean Car Fax but being a convertible it is possible that the interior could have gotten wet. Which might also go with the other response about the BCM.

The dealership that told you that they couldn't pull the codes since the lights where off was wrong. As long as someone doesn't go in and clear them they should be stored in the computer. I had a check engine light comes on and scanned it myself, but drove for about 50 miles. Turned it off and came back later and started it and the light was off. I could still pull the code which was for the throttle body that I had put on. It never came back on. Hope it gets fixed.

Carfax is a joke don't rely on it.

If they can't fix it do a lemon law and buy a new one from a trusted dealer.

Even if the symptoms are for the BCM any module could be to blame... just less likely

Thanks for the info. It's just hard to believe anyone. The dealer said unless the check engine lights are on there are no codes. Go figure! This time we made sure we got print outs of the codes! So even if the lights not on Monday when they check it something has to be done! Very unsafe to drive!!!

Very true! Something has to be done! Their going to have to do something. Start with the obvious and if that doesn't help go to the next thing. Hope they can fix it! Hate to have to get rid of the car!

Yes we agree! Don't know if we can lemon law it since it's not new. At least it was a certified car and we're not having to pay out of pocket for all of it. So far we have lost a bit though. The battery, our time, $ to drive 8 hours to try to get it home and still no car! Very upset!

You haven't mentioned the dealer you bought the car from. If it was me, I'd drive up to their front door, park and toss the keys to the salesman who sold it to me.
