Used car w/36,000 miles and/or 1 yr wrnty. Under a yr, but outside of mileage, check eng light starts coming on to the day, from Feb 28, 2017 to May 28, 2017. From Feb 28 to Mar 27 to April 27 have had to do oil change. Check eng light would no longer be on after oil change. Then car started making excessively loud noise at 77,000 miles so loud no one could hear me while on my blue tooth. Chevy dealer & a shop ran a diagnostic but no error codes in April & May. Shop tells me tires are cupping, I need new tires that were pretty much new at used car dealer. Chevy dealer tells me no error codes on diagnostic plus I need wheel hub bearings, tire shop tells me the tires need replacing, does a thorough inspect while car is on lift, says problem is struts in front need replacing immediately & shocks need replacing soon on back then says wheel hub bearings are fine, it's the hub bracket that is loose & making rattling noise along with bad tire noise. This is at 80,000 miles. Got tires, no money to do other work. Small local shop near home confirms big O is correct, tires are cupped & it's due to bad front shocks. Highly unusual for 80,000 miles May 3 dealer looks at reason for deceleration which started end of April, slowing to almost a crawl on freeway while accelerator is pressed all the way down to floor, dealer says they drove car, can't find problem. Couldn't be, mileage on car same when picked up as when dropped off. May 28, 2017 check engine light is on, car started knocking, got to work 70 miles from home, noticed on a full tank of gas, car was using fuel at rapid pace sitting on idle in parking lot. Started with 214 miles to drive on full tank of gas, indicator shows 104 miles left off 70 mile trip then dropped to 96 while sitting idle for a less than a minute in parking lot! mother tells me turn off engine. Said check to see if fuel is dripping under car. It is not.
