Multiple parts in my engine have malfunctioned in the past year, the most recent being a tube bursting and getting coolant everywhere. Other problems have been with valves, temperature gauges and even the radiator. It-??s like something new breaks every month. I have had every issue fixed and usually I don-??t get a warning lamp until I-??m broken down on the side of the road.

My 2013 Chevy Sonic developed ticking sound shortly after I bought it at 60000 miles. The ticking got worse over time and then check engine light came on. I scanned the codes and multiple four codes were found. P0171, P0496, P1101, and P2270. After doing some research it seemed to be that most Cruze, Sonic, and trax vehicles all had the same issues. I took it to the dealer for diagnostics and was informed the vehicle needed a new intake manifold, purge valve, PCV hose, and valve cover. They called the dealership to see if there were any recalls and the only one was the valve cover but would have to pay for diagnostics to see if they would cover it or not. The breather diaphragm in the valve cover goes bad due to a fault intake manifold on these vehicle models. There is a little orange gasket in the manifold that goes bad and causes the diaphragm to go out resulting in having to replace the entire system. The intake manifold not only causes ghat issue but causes the car to get jumpy at stops and stalling out. Have almost had a few people rear end me due to this. The purge valve goes out as well and when at the fuel pump the car will hesitate to crank or run at very low idle shutting off multiple times before it starts up and then runs rough until a decent amount of fuel has ran through the engine. The car would not get enough fuel when at stops or on highways and would also just lose fuel and cut the engine off. Those components have since been replaced by myself and no more issues. Chevy will not recall the parts that are causing the issues and therefore there is a safety issue when out on the highways.

The fuel system is running weak, for a car with only 30000 miles, one owner and full maintenance, the engine light came and go all the time and everything was checking

The PCV pressure reg valve fails and causes damage to the engine. GM sent a letter to customers but only covers the work up to 120K miles. Mine failed at 125K miles and cost over $1000 to fix. GM is refusing to pay for the repairs.10/15/2020

I purchased my vehicle 3 years ago preowned from the dealer and within these 3 years I have already had a catalytic converter recall, the issue recently is my ac system in my car is out and as a did research on the specific year there's people who have already replaced the ac system up to 5 times for 2013 Sonics. This is a manufacturing issue that needs to be fixed on Chevrolet's behalf.

Leaking water pump

- Watertown, NY, USA

My car has leaked out its entire coolant twice now within a six month period. This time it has leaked fluid onto the computer causing further issues than after the first fix. The lack of a temperature gauge to prevent the car from overheating is a huge issue. I constantly make sure there is coolant before driving the vehicle and all in the same day it has emptied without my knowledge causing a check engine light and breakdown instantly. It has happened twice now with my toddler in the vehicle, this should be a recall because fortunately it has happened while on street roads, where I could immediately and safely move into a parking lot, and not the highway but this situation puts my child's health at risk and that I am not okay with.

I was driving to work and was coming up to an intersection I had to turn at. I pushed the break pedal, but it was really stiff and didn't do much. My car slid across the road into a wooden electric pole because it would not stop. My car is totaled and now I have to figure out some way to get a different vehicle.

Code P0171 and P0420. I have replaced everything in the car that these codes state. New thermostat, catalytic converter, both 02 sensors, exhaust hose. Fixes for a few days to a week and the same codes keep coming back. Now the button on my gear shift sticks keeping the gear shift from locking into place. This stops me from being able to turn my car completely off and removing key from ignition.

- Myerstown, PA, USA

The Sonic now runs very spotty, poor acceleration, and slow bumpy idle. Prior ball joint was replaced and the cv axil, entire engine replaced. Believe it or not, water pump replaced. These repairs, with receipts, constitute a lemon law breach. I should be entitled to a new car or compensated. Yes, the suspension issue did happen while I was driving, as well as the engine. Will upload documents soon.oh, one last thing, very difficult removing key from ignition, been going on 4 months.

When the car is first started and turned off, the horn goes off each time. If parked but still running, the horn goes off every 2-3 minutes. When locking the car, it doesn't make any noise indicating it has been locked. When phone is plugged in, the music doesn't always work properly. There is a piece to one of the hoses that broke and is now making car run lean. When idling (at a red light or stop sign) the engine shakes vigorously and is harder to get back speed. When car is running and the hood is open, there is a hissing sound.

Takata recall - the engine has been misfiring this has also happen to someone else I know who has had the same vehicle. This is very unsafe and they don't have it as a recall yet but all of the dealership are aware of it. The vehicle jerks when your driving or when its parked. This is not the alternator or anything else I had that replaced and nothing was wrong with it and the same issue is still occurring. It a bad part they put in the engine and it neeeds to be recalled. It is unfair and not safe for customers with this issue. The vehicle jerks and when is does it it feels like it hesitates to drive while in drive mode. This has been happening for a couple of months it has just gotten worse and I am truly scared.

I have found one new leak and one leak that has been there for at least a year. The new leak is the radiator. It is leaking at the top on the driver side right where the plastic and aluminum meet. The other leak is the plastic thermostat housing. Current miles: 69,500
