Cadillac - Escalade :: 2009 - Shudder Going Uphill?
I own a 2009 Cadillac Escalade (no I don't write rap tunes) and for the past 5 years it has been an excellent vehicle to drive. It still is, but under certain conditions I am experiencing a shudder which lowers the confidence that I usually have in my vehicle. Specifically, when I am climbing a hill and the transmission is in a higher gear, say 4th and the RPMs are relatively low, say 1800, I feel a shudder as the car goes up the hill. When I let my foot off the gas the shudder stops. If I manually shift into a lower gear and raise the RPMs, the engine responds with power galore and I climb the hill without any effort and without any shudder (most of the time). The engine is smooth and is not sputtering when this shudder happens. I do not hear any unusual sounds under the car when this happens.
I took it to the GM dealer and they did all they could (analyzed the car for codes, monitored fuel flow rates, searched for GM bulletins, etc) but their response was "we experienced the shudder but cannot find the issue - bring it back when it gets worse". I read that BG44K will do a good job of cleaning the fuel system in the engine so I tried that but nothing changed. I have about 50K miles on the car and did my 50K maintenance just before a cross-country trip; on the way back from this long trip is when this issue started. The 50K maintenance included changing the transmission fluid and cleaning the filter (not replacing it), changing the differential oil, the transfer case oil, engine oil and filter, inspecting the vehicle, etc. I will continue to drive the vehicle and will bring it back to the dealer if it gets worse, but I'm wondering what I'm supposed to do if it never does and I continually experience this shudder. Or what happens if it gets worse all of a sudden and I'm unable to drive the car up a hill at all?

Do I have to pull out the complete switch assembly, or could it be some thing else?
View 4 RepliesJaguar - Xj6 :: Misfiring Cylinder 5 / Car Started Shaking With CEL Came On
I used fuel injector cleaner in two different gas tanks; the car started shaking and the check engine light came on. The mechanic changed a sensor but the car was doing the same; I was told that it will take 4 full gas tanks to clean the gas lines. I went to autozone and they told me that the car had a misfire on cylinder 5 and multiple misfire as well. I do not trust the mechanic any more since I had to take the car back to them several times and still is not fixed. They also did a full tune up and the check engine light still on and flashes when I am going about 55 mph.
View 3 RepliesBrakes - Gasoline - Steering - Chevrolet - Cobalt :: 2007 - Car Started Drifting Backward
My wife was about to pull off of our hill (facing uphill) to go to work. She said she stopped, held on the brake, and looked back and forth. She then went to press the gas and the pedal wouldn't respond (no rev either) but the engine WAS on. The car started drifting backward and she said that both the steering and the brakes were very difficult to control (power and brake assist had disappeared). She was able to guide it back into the driveway and get it parked. She said that when she got it parked, she turned it off and started it up again. She tried the gas and it worked and she tried the steering and brakes and both worked. She stayed home today while we try to figure out what's going on with it for fear that it will happen again.
I initially thought some sort of power loss but she said that the radio stayed on. There were no dash warning lights or sounds indicated to her and she said that there were no unusual sounds from the car during this whole thing.
Ford - Bronco - Transmissions :: Shifting Drive Selector Is Off By One
The drive selector on my 2000 Ford Explorer Automatic 4.0L will not allow selection of low gear. The selections are shifted to the right so the last one, low gear will not select. When in park, P, it shows R. When in drive, D, it shows as 2 and when in 2 it shows as 1. Then it will not allow to shift in to 1.The settings are off by 1 knotch. what's up with that? It runs fine but cant get to low.
View 5 RepliesMercedes-benz - Clk-class :: Hydraulic Lines Broke Again
I have a '05 Mercedes CLK320 convertible that I purchased 3 years ago with about 29,000 miles on it. Two years ago the hydraulic lines in the top blew and I spent about $3,000 to have it repaired. Today, the lines blew again. What I'm trying to find out is: - Is this common in this car? Or in any convertible?- Did I just get a lemon?- If this isn't a common problem, should the dealer that repaired the hydraulics 2 years ago fix them again for free?
It only has 70,000 miles on it now and I was under the impression that I could drive a Mercedes for a couple hundred thousand miles without a too much mechanical problem. But if this is going to be an ongoing issue, I'm going to get rid of the car, even though I absolutely love it. It's ruby red, of course!
Bmw - Transmissions :: 1998 - Clunks When Shift Into The Next Gear
I have a 1998 bmw 528i (e39) with 200k on it. It runs and drives like a dream except for one little thing.... when shifting into the next gear at around 25mph, if I let off the gas just before it shifts it clunks as it shifts into the next gear. However, if I accelerate through the gear change it is smooth as can be and has no problems through the gears.
Secondly and I believe unrelated, I am also looking for the location of a transmission temperature sensor... I have heard they tend to fail and can cause issues with shifting until the car is up to running temp. I experienced an issues with it once not wanting to shift out of 1st gear until it warmed but that was before a filter and fluid change. Since that, I haven't any issues, but I want to be prepared just in case with one on hand ready to go in.
Mazda - Engines - Noises - Mpv :: Car Started Whining Like A Jet Engine At Highway Speeds
A few months ago my car started whining at highway speeds. The noise has increased in pitch and volume, and is not dependent on engine speed--in fact, if I turn the engine off and coast, the whine persists, lowering in pitch (and getting quieter) when the car slows down. Recently the car has also started vibrating when I turn slightly to the right, as when I change lanes on the highway or bank right on a long turn (sharp right turns from a full stop don't elicit any noise). Do I have a problem with my alignment? I notice my tire wear looks a bit uneven.
View 4 RepliesFord - Mustang :: 1968 - Starter Noise When Disengaging
I have a 1968 Mustang with a straight 6. From all the research that I could do, the engine appears to be correct for the car.
I replaced the starter with one from AutoZone - DuraLast. The starter engages fine - no noise and the car starts fine. The noise comes when the starter disengages. The noise only last a few seconds. Sometimes it is very loud other times it is very brief.
I did a compare of the old starter to the new starter and noticed that the gear in the old starter sites further back in the starter housing then the new starter. Not sure if that is the issue. I have tried to do some searches to get some views of the starter but no luck.
Coolant - Radiators :: 1996 Honda Accord - Smoking From Under The Hood
My '96 Honda Accord started smoking from under the hood as I pulled into my garage today. Upon closer inspection it seems like it was steam, not smoke, and it came from a crack in what I assume was some portion of my coolant line. The crack is in a solid, plastic tube that runs right along the fore-most part of the car, right along where the latch to unlock the hood. There is an escape valve that warns not to open it while the engine is hot because of the coolant that will be under pressure, hence the supposition that it is leaking heated coolant.
Obviously this needs to be fixed. So I have a few questions.What could have caused the crack?Is there a way to repair the crack without replacing the part?How serious if this / How far can I get away with driving?
