Major Problem with 2011 L99
I have a 2011 L99 SS. Lately I have had several incidents where I am at cruising speed (anywhere between 30 mph and 55 mph) where all of the sudden my car will down shift to 1st or 2nd gear and my door locks unlock and lock again. I took it to the dealer and they could not replicate the issue and have never heard of such a thing.
Has anyone experienced this problem? I sure would like to know what's going on!!! |

Here's what Lou wrote as his problem. "Tech said that error codes still indicated low voltage. Error codes made him check voltage readings on the TRANS. control module and the ECM. The voltage readings ranged from 11-14 voltes. He said this wasn't normal. Starting with fuse block under the hood. With the car running he started checking fuses, modules and wires. While doing so the car went dead. This led him to find the nut was loose that was holding the power wire feeding the main fuse block. Hard to believe that was all it was making the car go so crazy!! So with all that said we hope that it's really fixed. All error codes cleared and readings are normal. Even though we were out $300 for the battery we didn't need we really hope it truly is fixed!!! Going almost 3 weeks without a car is a horrible inconvience!!! " |

Thanks for the suggestions. We'll start looking for loose wiring.
