The possible causes of this intermittent loss of power include a faulty oxygen sensor, weak fuel pump and/or clogged filter, vacuum leaks, ignition system malfunctions, bad valve timing if the timing belt or chain is worn or skipped, blocked exhaust...
Hello there, The Chevy Aveo most certainly does come with a 4 speed automatic transmission. The 5th gear you may be feeling is the overdrive function of the 4th gear. 18 mpg seems quite low for this size of vehicle...
In the interest of your safety, I would avoid driving your car. According to Chevrolet, the motor in that particular car is an interference engine. This means that, if the timing is off, the valves can make contact with the...
Hi there. Check the fuel pressure regulator (https://www.yourmechanic.com/services/fuel-pressure-regulator-replacement) and make sure that its working and plugged in. Put a fuel pressure tester on the fuel rail and make sure that there is good fuel pressure of 45 to 65 psi....
EPA ratings for this vehicle are stated in units of miles and gallons. The city driving rating for the vehicle is 22 MPG (miles per gallon). The highway driving rating is 32 MPG. Your experience is reported as 15 MPG...
Hello. The key issue is probably due to a worn ignition cylinder. Replacing the cylinder (https://www.yourmechanic.com/services/ignition-lock-cylinder-replacement) should do the trick. These vehicles are also known for having the key completely stuck in the ignition due to a failure in the...
Hello. We will be happy to assist you. A vehicle overheating could cause harm to engine components such as sensors, fuses, spark plug wires, pistons and gaskets. The vehicle most likely overheated due to a faulty water pump and thermostat...
The airbag light indicates a malfunction in the system. The system is always monitored for faults. It could be the airbag itself, wiring, or the impact sensors. The system will need scanned to see what trouble code is set. If...
What you are describing sounds like a bad or worn out ball joint. A ball joint is designed to pivot through multiple planes. Of course, because the ball joint constantly pivots at different angles, it tends to wear out more...
If you are operating in a cold climate, GM Technical Service Bulletin 08-06-04-004 might be relevant to your problem. To implement the repair outlined in the Bulletin, or if not applicable find the root cause of the misoperation, the relevant...
Hey there. I would first recommend checking the transmission fluid (https://www.yourmechanic.com/services/transmission-fluid-service) to be sure it has the proper amount of fluid in it. Low transmission fluid can definitely cause slipping (https://www.yourmechanic.com/article/is-it-safe-to-drive-with-a-slipping-transmission). Also, check to be sure there are no Check...
The Aveo's computer needs to "see" the brake light switch input, in order to switch out of park. With the key on and engine off, the brake lights need to be checked to see if they are coming on when...
The key is binding possibly because the ignition is binding or the shift interlock has a problem. The vehicle will need diagnosed for ignition switch, linkage or the shift interlock problem. I recommend you have a mechanic, like ones from...
It sounds like you may have a dirty or failing idle air control valve. The idle air control valve (https://www.yourmechanic.com/services/idle-control-valve-replacement) monitors the air intake as it is mixed with fuel prior to being injected into the engine at low speeds...
Hi, thanks for writing in. If your slave cylinder is leaking in this vehicle, I would not recommend driving it at all. It is very likely that within just a few applications of the clutch, you could lose all of...
The first and easiest thing to check would be the fuse. If that's ok, check to see if the switch on the brake pedal itself hasn't fallen off. If that doesn't solve your problem, I recommend having a mechanic, such...
What you are describing is a series of electrical failures but whether there is a common cause (such as a main fuse) will not be knowable until a diagnostic is performed. That diagnostic would consist, in part, of basic circuit...
Cold weather is hard on batteries and it sounds like yours is dead. There is enough power to light the dashboard until you try to draw power to the starter, Then everything goes dead, the starter solenoid drops back, the...
A faulty temperature gauge should be ruled out (direct temperature measurement would accomplish that) but, based on the "sequence" you are describing it does sound like real overheating. Other causes of overheating, not included in your list, are trapped air,...
