Yet the Chevy Aveo continues to exist, despite being even worse Daewoo garbage. That and the many Cobalts. Many vehicles, not just Saturn, used the 2.2L Ecotec with its infamous timing chain tensioner issues pretty much destroying them much like Mopar with its infamous 2.7L V6 used in the equally extinct 'cloud cars' such as the Stratus and Breeze, and some others like the Sebring and Avenger.
The original tensioner failed a month after I got the car in 2016, and jumped a tooth then, causing a CEL and a no-idle situation. Had to feather the throttle to keep it going or start it. All the OBDII gave me was 'P0300, random misfire detected'
The tensioner was recalled on 2004 IONs, but my 2005 had the same lousy part but didn't benefit as it was a 2005, not a 2004. They revised this thing three times and they're all failing. Timing chains, not belts, should last the life of the car. Not the case with this piece of junk. I was surprised how little torque was needed to remove the camshafts. If this were my 5.2L V8 in my old Fifth Avenue, you'd need an impact to break them loose. On this flimsy pile of junk, I did it with a 1/4 ratchet. No effort at all. I've needed more effort to break the crank bearings loose on an EZGO EH29C engine.
Quite frankly, I'm amazed the car made it to 107,635 miles (well, the digital odometer is stuck there since like 5 years ago! It just shows that and no longer counts up.)
But I still see a ton of IONs and other variants like the Aura and even the Sky (based on the same platform as the Pontiac Solstice). They're not uncommon in Kentucky.
I'm gonna just rebuild the top end to learn and know it can be done. Then I'm gonna hope to find my dream Malaise car and sell this one to someone once it's running again. What is the weird thing is I just changed the oil and filter and it was running perfectly fine, no noises or rattles, so I went to pay my utility bill, still running good. Went to get gas as it was nearing empty, and soon as I started it after that, it started making what I call 'wasps buzzing angrily in their nests' from the right side of the car. I knew it wasn't wasps, assuming (correctly) it might be timing chain rattle based on previous experience, so I drove home to get my phone (was going to work, didn't want to be caught somewhere broken down without some means to call for help) and I parked it idling in my driveway to get into the house for my phone, but soon as I got through the door, the car just stopped. Trying to restart it and it sounded hellish with noises and no compression (just spun freely making bike chain noises). Removed the valve cover and the exhaust camshaft was 45 degrees in the wrong direction and two cam phasers were just rolling around free (one broke in two) and the exhaust valve of cylinder 1 was higher than the rest.
