I wish it would throw something different, but so far just that. I leave it in my car so when it does show a light I can see what it is. Right now to read the codes I have my SCT X3 programmer from my Camaro. I have not had a scan tool when the engine light has been blinking, as I don't have access. It will probably stay off until next Thursday or Friday when I have to be doing major city stop and go driving. For example the code came back on Thursday night and went back off Saturday night. If I am not idling long I can go a long time not seeing a code, its just if I am remote starting in the morning, stuck in traffic, just extended period of time idling. Lately I have been driving the car more so the codes have been more frequent. Then just this month the idle has been getting very slightly worse and the car has been throwing the codes more. The car had a little idle hesitation throughout that time but didn't throw a code for about 3 months. Figured possibly bad gas, so got new gas, did an oil change, and cleared the code. The next day I checked the code it was a P0300. Went out to the car one night to go somewhere and it popped the engine light. The code started happening 3-4 months ago. Most of the mileage is during winter months because in the summer I drive my 2010 Camaro, but the Saturn is still driven daily. Its my daily driver, but as I said its not traveling long distances. The car will be 6 years in july, so its averaging a little more than 6k a year. In terms of time the car is actually on and operating is high, its just the distances aren't far. The mileage is low because its probably city driving 4 days a week and highway 3 days. I drive it everyday back and forth to work. It seems all the early 07 auras are having tranny problems due to this wave plate.Ĭar never sits unused. I hope they fixed it right for my long journey home. I am still waiting for the car, supposed to be done tomorrow, and then drive it back north. They had to do an overhaul and order parts to fix this issue. We were fortunate to catch this on the power train warranty. After research I have found this is a common issue with the drive train. They ended up taking the tranny apart and found that the wave plate snapped and the fragments made a mess and destroyed parts. They took it out with two techs for a good ride and came back reporting they felt the slipping. We brought it back and insisted something was wrong and they further investigate. We left the dealership and it started slipping bad and hesitating. They then said initially it was a misfire or bad gas, and we didn't have any codes either. We were literally two hours from closing time to get the car in to still be under the 5yr/100k warranty. So we called GM and they referred us to a local dealer. We ended up digging through her paper work and found her purchase date which was five years to the date she bought it. The service traction control light went off a few times, too. Having this happen 1500 miles from home is not a comforting feeling. Once here towards the end of the week the hesitation turned into slipping gears and clunking. Then we just drove it to Florida from New England and it drove well on the way down. We had it tuned up, replaced plugs, all fluids, coil packs, and it was still running a little rough and shuddering. My girlfriends 07 Aura XR 93k was hesitating and getting the traction control message on and off for a while.
