My auto started out with a Check Engine Light. I noticed the engine smelled of overheated radiator and coolant smell. Parts were replaced for fix (Hose)...but check engine light continued as well as the overheated coolant smell. The auto was placed for checking on machine for codes for check engine light, but none of codes made sense to Mechanic. Told to bring back for further testing/looks. Brought back several times. No idea what was wrong but last time I was told I needed to leave for extended testing and test driving as gears were not shifting in D struggled engine for me, no acceleration and RPMs raced at times. (Dangerous and unpredictable on highway and in town). Now I turned in for testing to Chev Mechanic, and now am facing a part that was replaced in control of electrical (over $500) and after they repaired that and tested I am told that I have a TOTAL TRANSMISSION REPAIR over $5200 - for a 2014 auto!!! It was in with dealership mechanics a total of 6-7 times. I was informed the electrical controls were confusing the engine reactions. Auto a dealers for $5200 + $500 repairs now 20230702 and problems seen & looked at since March for smell of overheating radiator, fix if hose (wonder if really needed), continued check engine light, refill of radiator fluid, codes checked and did not give correct evaluation. Eventually the transmission needs replaced out, at time that there is RPM revs, no acceleration while driving and gears heard to struggle in engine. Mileage now over 97000. Estimate on mileage, i do not have all documentation before me. Extended Powertrain warranty from dealership started at year 2015!!! Anything older not allowed, so I am told I have to pay the entire bill.

The vehicle has previously had the coolant reservoir and water outlet changed not very long ago. Not I am having the same issue with both of the parts again. Reservoir is cracked making coolant leak out and the water outlet is braking apart because it is plastic.

I bought this car used back in october 2017, I've had overheating problems, the dealership fixed twice under an extended warranty the third time I had to fix myself (they said my extended warranty expired). I noticed my key would get stuck in the ignition after putting the gear in park, I discovered the button on my gear shift is cracked and I have to pull it all the way put to remove the key. The latest adventure is I was driving on the highway in the fast lane at about 75 MPH when my car made a pop noise then slightly jerked then started to slow down. The check engine light came along with the traction light, I was able to safely get over to the shoulder I parked and cut the car off. After a few minutes I was able to start my car back up and get it to an auto store to find out why the check engine light was on. The codes that came back stated communication was lost with the TCM and the TCM internal temperature was too high. I was told the most likely solution is faulty wiring at the TCM. This is becoming a headache I'm still paying on this car and doing more repairing than scheduled maintenance

The warning chime that is supposed to sound is not working properly. There is a recall for this issue but the dealer said my vehicle is not included in the recall by the date it was made. The warning chime will not sound for certain warnings. My vehicle overheated and no warning sound was made. My vehicle tire went flat a while driving and no warning sound was made. If the turn signal is on the other warning sounds do not work I.e. Seatbelt warning chime. This is a major issue since I have had two warnings with no sound to alert me.

During last two months we had go to the dealer four time and three of these due to the engine noise and overheating. Last week smelled like fire and due to the gas inside the car we had to parking. When review the engine, there was not colant in it. The noise never stopped and some sensor were on during some days. This car is used for a pregnan woman and girls and are not safety for us for this reason we went to the dealer to see the posibility to change the car. So far, we waiting for the solution.
