So, My 2007 chevy aveo was running fine...then the check engine light comes on and the hold light begins to flash. The car runs fine. However, when I stop and begin to accelerate, the car will kinda "jump" when it shifts to 2nd and 3rd gear (i have an automatic, by the way). Later the hold light stopped flashing and it changed gears perfectly, but the check engine light remained on. What's going on???

take to autozone and have them run a scan. they will give a print out of code and possible replacement parts. remember they do not repair cars they sell parts.

check your hose's for small pin leak's. also check your thermostat housing and gasket. might be leaking from housing. might need a tune up if running rough. does your check engine light come on when car is running.

wrong fuel?? or run outta oil. or spark plugs.

I have a 2009 Chevy Aveo. The hold light has come on two times since I have owned the vehicle. The first time at about 37,000 (just out of warranty)the vehicle started running very poorly. the check engine light came on as well as the hold light blinking. At first I thought it was a transmission problem, It was NOT. The problem with this gem of a car is that the spark plugs need to be replaced by 35,000 miles. The check engine light was due to the ignition coil pack being bad (cylinder 3) All four need to be replaced at once. After replacing the coil pack and plugs the check engine light went out and the hold light went out. This was an extremely easy repair. I walked my 13 year old daughter through the repair.


The second time the hold light went on was about a week ago. I now have about 52,000 miles. The light came on for no apparent reason. The only unusual thing that happened was that i accidentally spun the tires in the rain just before the light came on. The owners manual will tell you to bring it in asap because there could be serious problems. I couldn't believe i was having another major problem (there was no check engine light on this time) My guess was that the spinning of the tires could have had something to do with causing the hold light to go on and blink. What i did was disconnect the battery over night in an attempt to reset the light. It worked, i have not seen the light come back on in over a week. I drive about 50 miles a day on the highway as well as stop and go traffic. Ill call that a win.


These lights come on for a reason, if the light comes back on i will be planning on taking it in to a transmission specialist. I am not trying to say you should ignore your lights but sometimes a little effort before taking it into your mechanic can save you a bunch of money. I just wanted to share what i did with you all. Also you can have your check engine codes read my many auto part stores usually at no charge.


I would never buy another Aveo or recommend one to anyone. In my opinion they are poorly manufactured vehicles. I guess i should have guessed that any vehicle with a 3 year 36k mile warranty has such a short warranty for a reason! I hope i could help someone with my experience.

Many things can cause this problem...unfortunately the only proven way to remidy this situation is to have your car scanned by a reputable mechanic with a diagonstic machine $40-$80. This will tell what exactly is causing the check engine light to come on, in the long run its much cheaper replacing whats wrong than trying to replace things that arnt wrong.

Get a scanner on it to see what error the computer has found.

the word HOLD is up near the clock on a 2004 Chevy Aveo. "HOLD" lights up. I'm not sure about the 2005 Aveo.

There is a Communication problem between the Transmission Control Module (TCM) and the Engine control module. That is the bad news and is why it's shutting down the engine. 
The good news is i believe there is a TSB recall on the 2004 - 2007 chevy aveo for the P0700 problem so it should be covered under warranty. 
Believe the TSB# 05-06-01-030D
Good luck and hope this helps and hope it's not a bad ECM. Check the wire harness to the ECM and TCM, look for broken wire or the harness it self gone apart. 

it sounds like a faulty sending unit the only way to know for sure is to install a mechanical gauge and measure pressure. or just replace the sender. it is not wise to drive it and just assume it is nothing major. if it is a mechanical problem will cost a lot more if you lock the engine up
