GM dealership misdiagnosed the transmission as needing replacement, and quote a $4500 repair price. After getting 3 alternative expert opinions, the problem was the throttle body; repaired for $420. Now the formerly recalled generator alternator has failed. Car will not restart when stopped, while driving. GM has told me they will not replace the formerly recalled part under warranty, or but not if for misdiagnosing the transmission and the part failing when garnering 2nd opinions. GM also told me that it is not the dealership's job to alert a customer of a recall. If that is their process for recalls, I am afraid for the lives of others. I am also afraid that they possibly don't even understand how to diagnose a vehicle problem in the first place. They confirmed the part now in question was functioning properly at their dealership, but recommended a new transmission due to high miles on the vehicle. This is a genuine GM dealership. I'd like the GM/alternator, control module, and other associate parts investigated for voltage failures related to throttle body failure. It is my understanding that if GM is replacing transmissions, when not needed, and the other parts eventually fully fail, consumers are at extreme risk. My 19 year old daughter was stuck at a complete stop, for nearly 30 seconds several times, on a 70 mph freeway, when traffic came to a halt, then restarted; reaching full speed and having to veer and slam on brakes to avoid her car; in the center lane. Please investigate. [xxx]. I will also be filing a complaint with the secretary of state of Michigan for vehicle repair shop regulation. Dealerships who are reading codes, and not verifying the codes, should be shut down for good. [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

I have a Buick power add on system that is 50 state carb legal called the stage one kit offered by GM the kit consists of an air intake and a software calibration. Among all the issues I have been having with the car their final solution was to install the oem calibration and fuel tables but leave the the stage one kit installed. I believe this makes my car non-50 state emissions compliant. Part number for stage kit is 12653664. The isntallation manual specifically mentions not driving without the calibration update from the dealer. I have no way of putting it back in.

On 3-7-15, upon leaving mcdonald's on 14 mile rd., in royal oak, mi. I approached the end of the driveway, stopped, waiting for traffic to clear. Starting to turn out of the driveway, I went to accelerate, the car did start to go, but suddenly, with no warning, the car would not accelerate. This occurred while I was now on the main road, with cars approaching, no acceleration. I glided into the driveway right next door, hardly made it safely. I tested the car in drive and reverse, and the car responded. I drove to the dealership, right lane, flashers on. They tested the car by computer coding "running lean". they determined this was the problem. I was called and told a loose cable and screw to the battery caused the problem. I asked and was told "running lean" had nothing to do with it. They said it coded previously "running lean". I never had warnings, or had no gas to the accelerator before. I have complained of a hesitancy when I go to accelerate from a stop. Test driving the car, nobody agreed with me, at somerset Buick or at sellers Buick. Told to me by somerset Buick, a problem has to occur 3 times before warning the driver. I said that could be "too late", and they could have a fatality on their hands. Imagine making a left turn in an intersection, starting to accelerate, and suddenly no gas to drive the car, in the middle of an intersection with cars coming" I pondered: The "3 time occurrence" before a warning? what reason not to warn a driver? how could there not be a warning to let a driver know that there is a cable and a screw loose causing no gas to the accelerator? I am haunted by what happened to all those people driving the GM cars that had the problems with the ignition. Will history repeat itself" I really believe this needs to be a recall situation to save lives.
