“I purchased my car about a year a half ago and it has been giving me non stop engine and leak issues. I have a 2015 chevy Sonic turbo and so far I have taken it to the mechanic 8 times to fix coolant leaks, fix my fuel thermostat as well as replace a head gasket after having it blow.”

“June 2015 the dealer switched cars when we refused the options at the closing of the deal to a base/standard car. A week or so after purchasing the car a tire popped as we drove down the street. It is very loud in the morning. A high pitched squeaking sound. Next we have been smelling gas,oil/fluid leaking from the car. The driveway is stained from it. The thermostat has been changed 3 times. It has been jerking,stalking, sputtering. The antifreeze reservoir has boiled over several times. It smells like something electrical is burning. The air conditioner doesn't cool well. …”

“My cars coolant is leaking and the source is unknown. My car has overheated twice and my mechanic has been unable to find what needs to be repaired. The coolant has need to to be filled twice within a 6 month period. Now my car is having other issues with the catalyst system that lead me to believe the coolant leak might be affecting these other parts. My catalytic converter was already replaced and the same code has popped up 4 months later.”
