Has anyone heard of the 1.6 L Aveo engines (2006) going bad around 100,000 miles?

[Steverino]

I have had a few people tell me that the Aveo engines (1.6L) tend to die/go around 100,000 miles and was wondering if you fellow owners have been going over this mileage without major problems? My 2006 Sedan has just over 80,000 miles now and would think about trading in for a Sonic if this seems to be true. I take good care of mine with regular up keep. I run Mobil 1 oil and change every 7,500 miles, changed the timing belt at 60,000 as they recommend, run Bosch Plat. +4 spark plugs and repair things as needed.

I imagine it has to do with the timing belt breaking before 100k when they don't change it before the 60k mark.. Or the fact that many dealerships are replacing the timing belts and not the tensioners or waters pumps at the same time. Or the fact that plastic parts need services about that same time (on every car) and can cause over heating. ETC.

NONE of those suggests the engine is flawed in design, just owners are flawed in maintenance..

Ditto. Keep up with the maintenance and you'll be fine.

Rabbit - which plastic parts need to be replaced?

Mine passed 100k a few months ago and now has 112k. Seems like it's just finally broken in. Runs like 12k miles.

OMG - NOT Mobil 1 - you will destroy your engine !!!!!

Which just goes to show that anyone can say just about anything related to cars - true, false - who knows? That said, in the case of our Aveos, this one is likely based on the ugly past history of the 2004, where timing belts were exploding every 15 seconds (at least I think that's what someone said). I didn't get around to changing the belt on my '05 until 93K, and at that mileage it looked new like right out of the box (yes, even bending it backwards). The WP and tensioner looked great also, and I have a feeling they all could have run many more trouble-free miles. But I'm not about to suggest that anyone should ignore the recommended change intervals.
I think that by doing the recommended stuff, especially the good oil changes, you could easily get 200K or more, if you want to keep the car that long. One of the plastic parts is the thermostat which will stress crack over time. Just replaced mine (metal now) a few weeks ago at 115K. Happy motoring for many more miles in your Aveo!

Mostly the coolant parts, the heat cool cycle, and the coolants "abrasive" nature tend to wear them from the inside out.

with age, they will crumble in you hands even though they look new. VW, mercedes, toyota etc have this problem as well. so it is not aveo specific.

100,000 hmmm? I am sitting at 171,000+ now in a 04 manual hatchback, but did have to rebuild due to timing belt at 65,000. I have not had another major issue with the motor since. Regular maintenance, 8.5mm plug wires, and various gasket replacements. Still does not leak any oil from anywhere, and does not run hot. Just replaced the body bushings in the rear, strut mounts in the front and swapped to coilovers. Next up is a replacement koyo radiator, since rocks have really done a number to the original throughout its life. The craziest part though, is that I originally rebuilt the whole car down to the roof skin after it was totalled at 3 months old.

Good to hear they have been going the distance. I would imagine the metal thermostat housing is an aftermarket part. Who makes it and where did you get it?

Well, there's a lot of people who think you just put gas in it and drive it...they never crack the hood open and inspect or service the engine...I think they should be happy for the 100,000 miles they DID get and even if they were driving the most well crafted car in the world it would eventually break down...an Aveo is no different. Just pop the hood open and be aware of what`s going on there that may need attention.
