On sat., July 2, 2016 I noticed a loud noise coming from the engine area. Being a holiday weekend, I had to wait to take it to the dealership on tues., July 5, 2016. I ended up taking it to a reputable mechanic that day after a runaround at the dealership and filing a complaint against them. The mechanic did not know how I made it to his shop. The timing chain was completely loose and tensioner had broke off inside as well as a couple of bolts. Looking at the oil nozzler it was blocked which could be causing...

lack of oil going to the tensioner/chain. I have read posts that this was an issue on certain saturn cars as well as timing chain. I purchased my car new in june 2003 and have maintained it very well, barely driving 5,000 mi./Yr. Keeping the oil changed when required. I am not certain if the car was in motion at the time this occurred or if it happened at start up. I was able to drive it to the mechanic, however, he did not see how I could have made it there due to the condition of the parts. I was driving on the fwy. At 65 mph and made it there safely.

This is the third time in one year that my timing chain has slipped on my 2003 saturn ion. I have read that the oil port is not large enough to handle oiling the chain. I have already paid out of pocket nearly 2000 dollars and it is still in the shop. It has messed up other parts of the engine every time it has done this. So I have to have other parts replaced also that are result of this. It runs fine then suddenly and without warning I can go to start the car and it starts having a spasm and then shutters and...

will not start. I am so afraid to keep having the timing chain fixed on this since I have read that it is really a fault in the engineering of the engine to start with. Please help. I need a number to call to see if there is a recall or will gm fix this problem that is surely their fault and not the fault of the owner of the car. It is a good running car and I did enjoy driving it but I can't keep getting the timing chain fixed if fixing the timing chain is not the problem really but is something else that is causing the timing chain to fail.

Timing chain broke, after having cleared a tune up only a couple weeks ago. No other problems with the car, and from doing some research I see that this was a problem with 2003 ions but gm had no recall information for me, on my profile page on their website. I am now without a car and no way to afford a new one, and the only thing I'm thankful for, is that I wasn't on the highway or anything when it happened, and it occurred when I tried to start my car. *Tr

Ask a mechanic spring 2014, we had the recall on the ignition fixed on my 2003 saturn. On september 9th my son drove the saturn to detroit mi. About half way there on i-94, at rush hour, the saturn lost power and began stopping. He was going about 70 miles/hour and didn't have extra keys on the key ring. Luckily, he is strong, smart and quick thinking. He was able to wrestle the steering column toward an exit, while depressing the clutch and restarting the car. Thankfully it started! If I had been driving...

the car, I don't think I could have done those things. We called the dealership that fixed the car and after numerous calls, they said they were not authorized to tow the car and fix it. Now several weeks later and in response to letters sent to gm executives, they tell us the same thing. I am telling them their fix is not a fix! I don't want others injured or dead. Why is this entitled 'ask a mechanic'? We were told many years ago by a mechanic at the saturn dealer not to hang extra keys on our ring. This dealer has been gone for many years. Maybe someone needs to ask a current mechanic if this is the right fix for gm vehicles. *Tr

car will not surrender the ignition key for in hour. Already had new key made at chapman chevrolet which makes starting somewhat easier, before, it would take, often times, 10min or more just to get the key to turn. Please help chapman chevrolet get the parts they need or stop ignoring my request for the honoring of the recall work I requested of them. Im afraid this will not hold up much longer as is. *Tr

When I bought my car it wouldn't start, the dealer said it was because it sat for a long time. This problemhas been constantly been an issue since in extreme weather. I was told during one shop inspection it was electrical and they have seen a lot of this but don't know what causes it. With this case it has shut my radio on and off and a big issue that I have is when I am stopped with my foot on my brake the engine will rev up and jerk forward. This happens in the city when I'm driving at slower speeds. I've had to...

run off the road to avoid hitting people, the only thing that saves me from hitting anyone at lights or signs is my safety gap between me and a front car. I've been late for work, ruined vacations, been stranded with an infant in 100 degree weather, and wasted a lot of money trying to find the problems. I bought it new and have heard every excuse for the problems...You guys have finally stepped in on one of the problems we have been having now gm needs to answer the rest. I'm not the only one with these problems. If you do a search online you can pull up 100s of issues exactly the same. I have all my receipts when I took it onto saturn dealers. Now I have doors that don't seal but I'm sure this is because it's old or other excuses. I had to buy another car because my kids aren't safe in it. I can't even have a clean conscious trading it in so I still am stuck with it. I have complained about this issue before but no one listens. *Tr

On multiple occasions this vehicle has accelerated without pushing the gas pedal, with no cruise control option, it's unsolved by multiple mechanics. Sometimes the brake works while it's happening, sometimes it doesn't, the most recent time I pulled into a parking lot where I had to hold the brake down to shut the car off, I could smell the transmission, I turned vehicle off, turned it back on and it went to over 5 rpm still, turned back off, sat and waited, it was 2am so I couldn't call anyone. After 10 minutes it...

finally went back to normal. That was the most severe, it's had slightly similar issues at least 4 times. First mechanic said it was a cruise control issue, then I told him I was leaving since the vehicle doesn't have cruise control at all. Don't want him working on it. 2Nd one ran computer check, no issue found. Hopefully gm recalls this before it kills someone. This car has had many issues me and my father could fix, ignition switch, wiper blade transmission, coolant light but this one isn't easy. *Tr

Acceleration & cruise controlEngine & cooling

On multiple occasions over the last 2-3yrs, the car was turned on and the engine revved up to 3,500rpm without pressing on the gas pedal. If I put the car in drive while this was happening, the car would accelerate on its own (up to 25mph). I've had multiple auto shops inspect and try to diagnose the problem but none can tell me what the problem is. *Tr

On 4 separate occasions (different dates, most recent were 1-26-2014 & 2-19-2014) engine revved and car accelerated by itself without gas pedal depressed. Most serious occurrence, car accelerated, brakes had no effect (pushed to the floor), ran red light, went off road, slammed transmission into park to stop. Shut off car, then started it again, and it ran normal. Took car to mechanic. No computer codes. Nothing mechanical was found to be wrong. This is an extremely serious safety issue due to the inevitability of a collision with something or someone. *Tr

Wife and children riding down road when car turns itself off and looses all power. She was luckily enough to merge across 2 lanes at a coast with no brakes or power steering to bring the car to a stop. Then it took up to 30 min of sitting on the side of very busy i-16 till the security light stopped flashing and she could continue her way home with my 2 and 8 year old kids in the car. Now all the car will do is flash that passlock light after I have replaced the ignition switch,starter,battery,alternator and many fuses also following the relearn procedure each time. *Tr
