I purchased this vehicle used in December 2014, the very first night driving it home, the engine would nit start. I immediately called the dealer, took the car back and watched as they ran a diagnostic. Nothing was wrong with it. I did some research and it seems to be a normal issue with the make and model. Then I noticed the faulty gas guage, reading low fuel then all of a sudden I have gas. Again, contacted the dealer, took it back and yet again, diagnostic ran with clear readings. I looked up thaylt issue and of course, complaints about the same issue were common. Finally, on April 9th I was on my way home and was involved in an accident. It was a front impact accident which totaled the vehicle. The air bags failed to deploy. The windshield was completely shattered, glass flew everywhere. After the front impact, the vehicle rolled over then landed on on the passengers side. …

I bought my car from a used car lot. I had it about 3-4 months and out of the blue it overheated very quickly, the warning light was on, some type of loud buzzer was going off so I pulled over and let it cool off, it took about 45 minutes but it started back up. I checked all the fluids and coolant levels and everything was ok. This continued to happen for about 3 weeks, quickly overheat, lights, alarms pulled over, checked fluids over and over. After about 3 weeks it would quickly overheat and then shut off on its own and several times it happened so fast I barely got off the road.i took it to a mechanic that drove it around a little until it overheated which at this point only took about 3 minutes to happen. …
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.
