Sold my 92 year old mom, who is sharp, still working, and still driving, a 2014 Cadillac with ~ 40K miles on it. Barely six months in it needed $1000 of repairs for brakes and cooling system. The touch screen stopped working also, this will cost another $1200. Two recalls issued so far on the car since she purchased also. Total lemon. HEY HERB! Fix this. Taking advantage of an old lady is not cool.

UPDATE May 30 2019...
My mother's car was in repair shop for two months. She just got it back. They gave her a loaner car, but it took forever to resolve all this. She paid for the new brakes and cooling repairs ($947), but did not want to also pay for the touch screen. First the dealership tried to negotiate my mom down to $600 for the touch screen repair ...she refused. Then they agreed to honor their brand integrity and repair the touch screen at no charge. Just when she was due to get the car back, they called to tell her they found yet another new and mysterious "brake problem" that, what a coincidence, would cost about $500 to repair. This was purportedly a "failure of vacuum system" which left brakes with no power. Funny, they had just repaired the brakes at full cost. Ultimately, after a lot of stressful back and forth, in which they refused to give her her car back unless she paid more, she agreed to pay another $188.77 for some new parts installed, but refused to pay any more labor. At that point the dealer relented and accepted this, and returned her car.This has consumed my family's time for several months. Other family members in NH and MA have been Herb Chambers customers but I am not sure they will return.
