The check engine light came on and we brought it to the shop where they said the code is for the electronic brake system modulator. It is also causing the ABS to malfunction and be hypersensitive. There is a recall for the same make/model/year of vehicle, except the month before her car was manufactured. I believe this is a safety issue that needs to be looked into and that her car should also be a part of this recall. We purchased the car in mid November and the engine light showed up a couple weeks later. I contacted GM who said to contact this site to request further investigation for safety risks.
