    I find that the mechanics are somewhat low on knowledge of tire pressure. I suspect that they do not compensate the pressure for the temperature of the tires and inflate them to the 35 lbs when they are hot from driving. When the tire is cooled down the pressure drops. I personally have a compressor at home and check the tires before driving for the day and only inflate them cold, to 35 PSI (although I find that the built-in tire monitor system seems to read somewhat low and different from front to back). I seem to remember that the on board system does not light the tire warning light on the dashboard until the pressure in any tire drops below 27 PSI.
  • My 2008 cadillac cts has been making a rattling noise since about 20,000 miles. I took it to the dealer several times and they could never find anything. It has become quite loud and I waited until it was so loud that they couldn't miss it. It would make a loud pinging noise best heard at about 15mph.
    Now the dealer said that the entire driveshaft is loose and needs to be replaced. I have 55,000 miles so it is still covered under warranty. Overall I am very unhappy with this car. I think it is a piece of junk just like every other gm car I have ever owned.
    So if anyone has had a similar problem and was told they couldn't find anything, think of the driveshaft.

    Also keep a few quarts of oil in the trunk. If the engine dumps its oil suddenly (known defect but GM's not admitting to it), make sure to fill it up before taking it in as they'll blame you for running it with no oil in it. You'll know if this happens when the thing throws a rod or spins the bottom-end bearings. (sounds like an old 1970s Mercedes diesel - can't miss it.)

    NOTE - the oil won't usually go out the exhaust or an the ground but get several quarts worth trapped in the cat and muffler.

    The reason is that the engine oil needs to be replaced at every 3K miles, even though it is synthetic. If the protective agents in the oil give out, the lubrication drops to nearly zero. Traditional oil dies in a more gradual manner and has somewhat of a buffer - it just turns into sludge. Synthetics don't and get thinner as they age. GM's "official" recommendation to its mechanics is to change it at 6K and ignore the oil life sensor/readout. I'd stick to 3 months to be safe, since a new engine is an unbelievable cost versus regular oil changes.

    I have a Cadillac CTS. Rear wheel drive. 35,000 miles and new tires 4 months ago. It is so bad in snow it's absurd and it is very dangerous. I caution anyone who lives where it snows not to buy this car unless you put chains on the wheels. Even an inch of snow and this car is inoperable and highly dangerous. This is a 30k car--in snow I am stuck all the time and 10,000 dollar cars go whizzing by.
    I will get rid of this car asap. I don't know if GM did any testing on this car in snow but they could not possible have done any

    What kind of tires were put on the car 4 months ago? If they were "performance" tires, they're set up for very good grip at moderate & higher temperatures and almost none at all when it gets cold. So-called "all season" tires work better in the winter, but nothing beats dedicated winter tires in the (wait for it) winter.

    This sounds to me like a tire issue, not a car issue.

    Plus which, if you're used to FWD or AWD cars, driving a RWD car in the snow is a skill you may not have acquired. Bear in mind that until 20-30 years ago all cars were RWD and people did quite well with them, at least those who knew how to drive them.
  • The Cadillac CTS only has about 5 inches of clearance from the ground to the front apron. Any item over 5 inches tall, such as a dead racoon or ice chunk in the road, will cause damage to the vehicle.

    The Cadillac CTS is a rear wheel drive car. These drive systems used to be popular because the front wheel drive system was not yet invented . These became "rare" with the invention and perfection of front wheel drive. Front wheel drive pulls the car and the engine weight on top of the drive system makes a front wheel drive car virtually on level as four wheel drive.

    In addition, the Cadillac CTS has very wide tires. These will float on top of the snow and not dig in as a narrow tire will. So the Cadillac CTS is a very poor choice of a vehicle in winter driving conditions.

    You will place your occupants and yourself in a greater danger situation if you purchase this vehicle and intend to drive in ice or snow conditions. Consider a front wheel drive vehicle with higher road clearance.
  • Isn't the navigation system on 2008 and later CTS hard disk drive based??? Why would you need an "update disk"???

    How else are you going to get the software onto the hard drive?

    The nav system is hard disk based, but the actual map data is updated yearly to keep up with current roads and add new information. This new and updated information is included on the update disk. In many areas, such as Austin Texas, New roads and developments are being added very quickly. If you want current information on your nav system you need to purchase and install the update disc.

    I have owned my 2008 cadillac for 5 mths and I have taken it to the dealer 5 times all Electical problems replaced driver window motor, amplipher, some brake bracket (IDK), passenger side window won't defrost, door lock would not release, and just picked it up today for the rear defroster. I love this car just not committed to having a relationship with Cadillacs service department. It sucks that I lost my hard earned down payment.
    :(

    What do you mean by 'I lost my hard earned down payment" ?
  • dmathews3dmathews3 Posts: 1,739
    Maybe he didn't make his payments and the repo guys got it.
  • Obviously you were not reading the other posts. Little knowledge can be dangerous and can confuse a lot of people. Please do not misinform. First of all not all CTS's are rear wheel drives. It comes in AWD. Second the clearance you mentioned is the skirt made of thin soft rubber and a racoon will not damage it as it will bend springs back no problem. CTS is a high performance vehicle and comes with wide tires when bought but the tires are not meant for snow. If you read the other comments above, Winter tires are recommended and if you can afford a cadi you should be able to afford more safety for winter like snow tires.
    Like what other people said dont blame the car. Be a better driver or put on proper gears. You dont go out on winter wearing a summer shirt. You can if you want but its not recomended.

    I bought my 2008 CTS DI used in 2009. I have been to the dealership 4 times in the last couple months for different issues.
    1. Sunroof leak
    2. Had to come back b/c Sunroof was making loud noise after their fix
    3. Exhaust was rattling loudly
    4. All 4 rims peeled

    Now my steering wheel is shaking once I hit 50mph. I just got new tires and I had them balance them and then after I got a new tire after hitting road debris I had them balanced again and I still have the issue.

    The car is paid off so I really don't want to have to trade it in. I love the car and the way it drives, but having this kind of relationship with a dealer when the car is only 4 years old is not my idea of fun.

    Does anyone have the same issue? If so PLEASE share your experiences. Do you think it's wise of me to trade it in now? I just hit 50,000 miles on it so the warranty is up.

    Hi Mariah,

    Sorry it's taken me so long to respond. I had the problem a few months into owning the car.

    I took it to Moore Cadillac in Chantilly, VA for wind noise in the sunroof and the speakers. The service advisor told me that I didn't tell him the right noise to look for, needless to say I am never going back to Moore Cadillac. They had my car for 2 days and never fixed a thing. I also had to pay taxes for 2 days on a rental car. Completely ridiculous. Lindsay Cadillac in Alexandria, VA are excellent and have helped me with other issues. I gave up on the speaker issue though. I heard it again this morning. It's when some songs on the radio have more bass than others the speakers rattle.

    Hello pony00,

    It's great to hear you've found a place where you can be taken care of! I'm sorry that the speaker issue wasn't able to be fully remedied for you, though.

    If we can ever be of assistance, please email us at socialmedia@gm.com

    All the best,
    Sarah

    All OEM speakers do that at a specific frequency, which is why people who have their stereos loud all the time are probably going to want to install a subwoofer to keep the regular speakers from ratting themselves lose from their mounts over time.

    Fixing it is usually as simple as taking off the cover or getting into the trunk, putting a lock washer on the bolts/screws holding it in place, and adding a drop of low-strength (not permanent type) loc-tite.

    As for the wind noise, all sunroofs eventually do that as the gaskets distort and age from the repeated cycling between hot and cold during the day. Also, the tracks and mounts on these extra-large panoramic sunroofs can sag and distort a bit with age, just like, say, your doors will from wear and tear. The "fix" is usually a small amount of black gasket sealer at the right location - usually it takes just a thin painted-on layer not much thicker than a 3x5 card in a couple of inch area. It might take you a long time to figure out the exact location, though. Sometimes you get lucky and can feel a hole or gap with a piece of paper or similar. Sometimes you have to just get a bit lucky.

    did they do a road force balance....beleive that is what its called...on a Hunter balancing machine........that would be a proper balance...using more expensive...but better overall....
  • pony00pony00 Posts: 10
    Hi pao,

    Someone else told me that they might not have done a proper balance of the tires. I think I'm going to take it to a tire place so they can do it the right way like you said.

    Thanks for your post!
