The ABS wheel speed sensor wire harness has a failure issue. This leads to the ABS system activating without a warning light turning on and can increase the stopping distance when not necessary. The transmission may seem to clunk when accelerating from a stop as the computer doesn't read the correct speed sent from the hub assembly to the computer. Previously, I had a hub assembly replaced and the problems still existed. After replacing the wires the problems have not resurfaced.

Dash gauges, warning lights, & alarms, bells flash on & off and vehicle suddenly runs rough. Dash codes of all sorts blink on & off. New battery and new altenator installed, problem still exists. This happened first when driving on hiway. After vehicle pulled off road and engine turned off. The dash code then read battery issue. We tried to drive again but now vehicle operated roughly and there was no more daylight. We had vehicle towed 100 miles. Then paid for new battery problem did not change so we had a new altenator installed after having a diagnostic test advising the need for a new altenator. I am quite upset becaus ei feel that there is fraud on part of sears autorepair. Diagnostic said altenator was the problem. I paid over $450 for that service and another $150 for the battery.

I purchased this car on June 23 and the next day it wouldn't start took it back to the dealership and they replaced the battery and the alternator said it was fixed but several hours later the car wouldnt start again took it back the next day and they said it was the air conditioner running while the car was off draining the battery so they took the fuse out and said they would fix it the next day but when I called to take my car to them I got no answer from them. Three days later the car overheated and I got it completely checked by a different mechanic to see why my car is running hot and he gave me a list of problems every head gasket is blown out and the motor is gone. He said that there was a recall a few years back on these types of Buick cars for the coolant and the wrong coolant was placed in the car and it messed up all head gaskets I immediately called the dealership but again no response I called the bank because I still have a 30 day tag and only had the car for two weeks but again no response I called Buick and spoke with someone to ask about the coolant recall and he said he would call me back in a hour and again no response. I asked for a carfax report and the dealership said they didn't have one but gave the couple behind me a carfax for their car the brakes and rotors are completely gone I cannot stop with my brakes I just have to coast so I want hit anyone this car will stall out on me without any warning. There has been no action taken from the bank or the dealership on how we can fix this problem they have all been ignoring and not responding to my calls texts or anything.
