I do not know what system affects the problem my car is having it stalls in front of oncoming traffic on left turns it's done this to me 3 to 4 times and it scares me. It will start right back up and go but it'll still continuously throughout the day when I slow down or come to a red light. The speed control sensor went out and I replaced it and there seem to be middle or something on that. I've read different reports or seen on YouTube that people have reported the same problem with their cars it is definitely a safety issue had it not started up or had I panicked like I did the first time and almost not get it started but a car could crash into me because my car stalled in front of traffic the problem has not been reproduced for anybody and there has been no report to dealership insurance police anything like that. I have checked periodically to see if there is a recall on it and there hasn't been this is the first time I'm seeing where you can report something like this so I thought I would

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.

Takata recall: I purchased this vehicle Oct 9 2015 with 56K miles on it. From the day I purchased it up to today I have been hearing a humming/buzzing/whistling noise coming from the rear of the vehicle. I had it checked out by a repair shop and was told it was a faulty fuel pump with an estimated cost of $500. The noise can be heard only when the car is on and running and it can be heard inside and outside of the vehicle when stopped or moving. It can be heard from inside and outside the vehicle and has only got worse since the day I purchased it. I am a part time uber driver and I own a mobile cell phone repair business and I am in my running vehicle up to 15 hrs/day. I have researched this issue and there are many threds and blogs online with customers complaining of the same issue. I do not feel I should be responsible for this repair charges has the vehicle was making this noise soon after the purchase and I was not notified. This noise has started to affect me mentally as there is nothing I can do to drown it out. I is also starting to affect the performance of the vehicle. Please help. "takata recall" also, since the purchase of this vehicle I have noticed the ac does not blow cold air when sitting at an idle. I live in Arizona and temperatures can reach 120 degrees. As I mentioned I am in my vehicle up to 15 hrs/day and many of those hours are spent sitting idling while I repair my customers cell phones. When I am sitting in 120 degree heat with barely cool air blowing on me it makes it about 90 degrees in my vehicle which can cause health issues and worst case scenario death. I am at the verge of selling this vehicle, obtaining a lawyer, and filing a complaint or law suit, especially if my health is being affected. Please help.

While driving on the freeway my car suddenly lost all acceleration power. It ran 5K rpms to go 55 mph and the traction control light was on and the engine malfunction light was blinking. This has been an ongoing problem for a week and the dealership cannot figure out how to fix it. Sometimes the lights stay on and sometimes they go off even though I continue to have loss of acceleration and ridiculously high rpms to travel 35-55mph.

I get this loud annoying high pitched ringing sound coming from back wheels. The sound is so loud at times that pedestrians can hear it as I am driving down the street. It does this after I have been driving the car for 30 minutes or more. Once the ringing sound starts it will not stop no matter what speed I'm going or whether I am sitting in idol, park or in any gear. Chevrolet dealership repair department doesn't know what it is but said it may be the fuel pump. What concerns me is that the dealership repair department will not at least check the fuel pump which would eliminate this as the potential problem. It definitely is not a functional sound and it may be dangerous to continue to drive the car when it is making this sound.

Car has excessive gas consumption. It is presently getting only 24.9 miles to the gallon. Occasionally it will have a very strong sulfur odor coming from the exhaust pipe. I should be averaging about 34 miles per gallon with driving pattern which is a mix of city and highway mileage.
