  • 130,000 miles


I have owned my 2008 Saab 9-3 for about a year now and I have had an ongoing rough running issue that seems to be getting worse. When I start my car up in the morning it runs very rough and recently the check engine light has been turing on and off with cylinder misfire codes. I have done some research and had this problem diagnosed, several times, as having bad intake valves. After doing more research on this problem, I have come to find this is a rather common issue with this specific year make and model. This is concerning because I have had this repair quoted at over $2000. I am very familiar with manufacturer recalls and have been told by multiple dealerships to submit a complaint in order for this problem to be covered under a manufacturer recall due to faulty parts.

The contact owns a 2008 Saab 9-3. the contact stated that the vehicle overheated and stalled several times. The vehicle was taken to the dealer where the extension tank was replaced three times. The inner hose detached internally and the dealer provided no solution. The manufacturer was notified of the failure and provided no remedy. The contact was uncertain if the part was replaced a fourth time and if the failure would recur. The failure mileage was not available.

I have what I've searched is the "cold start problem". when starting the engine in cold weather, it takes it a try or two to start, but upon ignition, it sputters for a minute or two and once it warms, it runs perfectly fine. From reading reviews online, it sounds like many others have had this and it is the result of the valves going bad, meaning I need a whole new rebuild done. Car only has 127K miles on it and is in mint condition. Per the number of cases I've read online about this, it sounds like the '07-'08 models were the one's that were defective in my case. Bought the car recently from a friend who thought it was just a fuel pump issue needing to be replaced, which I'd pay the few hundred dollars for that, no problem. But now looking at close to $3,000 to have fixed??

I was driving at 55 miles per hour on the lodge freeway in metro detroit, I was in the left lane and there is no emergency lane on the left, and my engine turned off on itself (scary!). as we are aware, brakes pretty much stop working when the engine is off and I was driving with 55 mph with many vehicles around me. I managed to pull over to the right without getting hit. When I stopped, I tried to start the car, it would start for 5 seconds and it will stall and I had about 10 gallons of gasoline in the tank. I had to get the vehicles towed to my house. Next day I started reading the blogs online to figure out how it is possible for the engine to stall like that without any warnings, especially one is going at highway speed. It turned same thing happened to a lot of Saab owners as well - engine stalled without any warnings when they were driving. I hooked up the vehicles to a diagnostic computer and it showed that the crankshaft sensor stopped working. If there are other Saab owners with the same problems, we should do something to prevent any injuries - happy to discuss it with anybody.

The stock intake valves are bad, noticed problem at 75,000 miles and bought the car at 74,000. This is a very common problem for this year including engine failure. Over a 3,000$ fix.

Car was manufactured with a bad set of intake valves which is noted on many Saab owner threads. Valves break down in cold weather around 50K miles. Car starts and bottoms out sometimes and has rough idle until warmed. Accelerating while engine is cold can cause safety issue. Quoted repairs run $2000-3000.

Defective intake valves. Repair center specializing in Saab performed cold compression test on cylinders and found that 2 of 4 had low compression. Informed me that they have found 90% of the Saab they test from 2007-08 have this problem from cheap valves used specified by GM.

Intake valve issue - car will not start on a cold day and, sometimes at a stop sign /light, will stall - had to two mechanics depict the issue and it is the intake valve issue - many Saab's have reported this issue and nothing was done by GM - I called GM and they said that they are not responsible - this issue has been reported several times and there are several threads as well.

The contact owns a 2008 Saab 9-3. while starting the vehicle, it idled roughly. Additionally, the vehicle would sometimes take a long time to start. The vehicle was not diagnosed nor repaired. The manufacturer was not made aware of the failures. The failure mileage was 90,000.

I didn't have a problem with the car in southern California, but I moved to New York at about 75K miles - and I noticed a problem right away. Rough idling started, and would even turn on, then right back off. The problem was not an issue again during the summer months, so I was able to drive it to 83K miles. Now that it is winter time, even though it is garaged it will not start if it is under 45 degrees. I had it checked out with a certified Saab mechanic and he confirmed by way of compression test that it is indeed the dreaded intake valve problem. The estimate for repair is $2,230!

Hard/rough start especially in cold temperatures. Mechanic said #4 cylinder is misfiring. Confirmed to be low compression due to prematurely worn intake valves. #1 cylinder/intake valve is not far behind #4. became a serious problem when engine stalls when sitting in traffic. Also vehicle engine has stalled/shut off while driving at low speeds, for example, in parking lots, redlights, 4 way stops.

79,000 miles began with sluggish cold starts until warmed than began to run O.K until stopped turning over. Another owner of GM screwing the public with crappy valves installed in these engines. When will there be enough complaints to create a recall. Ordering parts from East coast Saab parts store and looking for reasonable and knowledgeable California based mechanic. Expecting to pay approximately $2K. Will update this complaint when job complete. Another GM disappointment in car ownership!

  • 84,000 miles
The engine lost total compression due to what the mechanic said was a well-documented case of intake valve failure, happened in northern California. The engine cut out while I was in traffic on the freeway, the car stopped, and the car was grazed from behind. Not much of a problem due to damage, just a quick re-paint of the back bumper, and paid out of pocket. The engine was gone. The Saab specialist told me that so many 9-3's, especially on the East coast, have experienced total intake valve failure like mine. I contacted Saab and they essentially said to go screw myself. Saab and a subsequent call to GM claimed they had "never heard of the issue" which my mechanic specialist said was a "bold lie" because there's an online history of this that I found, and they denied me any help in getting it fixed. Since the car was worth more than the $2,900 cost I had to pay to have the engine rebuilt, with the same faulty valves that will cause someone else trouble later as I traded in my car, I decided to repair it, and then get $1,200 more out of it once I traded in my car. You need to investigate this. It is not fair to owners who are out of pocket. There was a safety concern with my incident. If the car behind me had not been aware once the freeway started moving again, I could have been hurt. Saab and GM deny this, yet search google---"intake valve problems Saab 9-3" and you'll see for yourself. Make GM pay for this. People have lost a ton of money on depreciation alone, and now the engines fail, almost all of them, according to the shop who fixed my car and to what I've read online. Please issue a recall. Saab and GM were both especially arrogant to me. They should pay for this problem, and reimburse me what I was out even though I sold my car. I have the receipts if you need them. Thank you for listening! please email only.

I have the same issue that others have talked about. GM put cheap valves in engine--they have now failed for a number of us. Cold starting, rough idle, smell of gas, ultimately will not start. Expensive repair on car without much mileage 60K repair is 2500-3000 GM should fix these for free or reduced cost.

I first noticed a difference in how my car worked about a year and a half ago. I purchased it certified pre-owed from a certified Saab dealer at the time. When I first noticed the "cold-starts" I thought it was just normal wear and tear and maybe needed an oil change. I always use premium gasoline and get the vehicle serviced regularly by the dealer. When I took it to the dealer in the beginning of 2014, the technician said he's familiar with the problem that I was having. He says the issue is with the compression valve. He told me that I was "unlucky" that I purchased this car because Saab manufactured 2007-2009 9-3 model engines where the valves were made of weaker metals that when surrounding metals. As the edges of the valves impact the engine walls, their original convex designed became concave, thus causing a loss in pressure and combustion. (I'm not an engine savvy guy, so please excuse my lact of terminology). So, he quoted me about $3,000 for a valve replacement. That's rediculousness! how can GM produce a vehicle whose valves will deteriorate after normal wear and tear? this has led to not only cold starts but also decreased responsiveness on the highway. Sometimes when driving, I would apply the accelerator and my car shakes for a few seconds. When giving a ride to others they look at me like, "that's not supposed to happen." My car hasn't stalled or shut off while driving, but I'm guessing if I don't get this fixed soon it may happen. There is a safety issue that I'm sure GM is aware of; accordingly, there needs to be a recall to get this issue resolved.

9-3 4-cyl

  • 710,000 miles
At about 70,000 miles the car began to start rough on cold mornings this continued on until this year 2014-2015 it would barely start on all on a cold morning, after less then a minute of running it would be smooth with no apparent lose of power. All plugs and plug ignition coils we replaced with no effect. Finally I did a web search and found out a number of 9-3 Saab's 2006-2008 had bad metal in some of valves causing them to wear paper thin.once the engine was warm the metal expanded giving normal compression. A compression check on mine came back cycl 1,3,4 50lbs cycl 2 200lbs. This starting problem was first noticed at 70,000 I got the motor fixed at 92,000 miles. Of course the fix was a valve job and a cost to me of $2088.02. I feel Saab (GM) should share a large portion of this cost. This problem was very well documented on all the Saab forums. I hope anyone reading this and has the same problem please file a complaint this is not right.

My 2008 Saab 93 2.0T has intake valve failures. In the morning it idles rough until it warms up; this has been verified by a Saab specialist. My engine is not molded or altered in anyway other than the consumables over time (belts and such). A quick check for 2008 Saab valve problem leads to forums chalk full of other owners with the same issue. GM should foot the bill for this $2500+ rebuild of the engine that they poorly manufactured in the first place.

On the 2007-2011 Saab 9-39-3 there is a common issue with the intake valve seals going bad causing a rough idle and/or misfire on cold starts. Mine exhibits this behavior but is not still under warranty. This is not just wear and tear it is a bad part or bad design that is basically designed to fail. To fix this it costs $1500+ and GM should be responsible for a flaw in the vehicle regardless of the 5 year/100,000 mile warranty.
