Sonata I45 (YF - 2011+) :: Transmission Clunk When Downshift
2011 Sonata Limited ... I have just under 60k miles and did a tranny drain and refill at 24k and 55k. Just had the brake light switch replaced. For some reason when cruising with the car in overdrive, if I let off the gas to decelerate and ease into the gas again, I get a real hard down shift and shift. So every time I get on the gas again it is either kicking out of overdrive or downshifting and shifting back immediately. 99% of the time it is a hard thump. When I have the cruise set I do not notice this at all. It does it in ECO or out of ECO. This is new and I started noticing this after the brake switch replacement.

Car wouldn't start on Wednesday so wife had neighbor jump start the car and she took it to the auto store and had the original battery replaced. On Friday, while driving the car, the battery light came on so she took it to the auto store to have the battery checked. When they went out to check it the car wouldn't start, only click. The battery has a full charge and doesn't drop when the key is turned. I pulled the starter and had it checked...it's good. I've checked relays and fuses and am coming up with nothing.

I have noticed a significant (15 to 20%) drop-off in mpg in the last 6 months or so. My 2006 prius at 95,000 miles is just short of the warranty on the battery pack. I brought it into the dealership and they ran the routine computer diagnostics and said everything looks good. I fully expected them to tell me that the performance on the battery pack had fallen off, so I was a bit put out. The guy actually got a bit defensive with me when I asked him some further questions about what the criteria are for determining whether the battery back was performing as it is supposed to in order to get the maximum MPGs.
View 3 RepliesSonata NF (2006-10) :: Transmission Harsh Shifts When Cold
I bought a 2010 GLS 4cyl and within the first week started having shifting issues. Initially it was only when it was colder than 30 degrees outside and would only shift harshly between 1st and 2nd. Once I had driven a few miles and warmed the car up, everything was OK. It's still an intermittent issue, but now it will do it when outside morning temps are in the 50's and 60's.
I've read the TSB for 6cyl 09's and saw a post in the Santa Fe forum that sounded identical, so at least I'm not the first to experience this.
I took it back to the dealership knowing it probably would not shift badly when they test drove it because we had run out of cold mornings. I picked the car up after they reset adaptive learning and said there were no updates available for the computer. (And also being told I had bad gas in the car. Another story for another time...)
Until it starts doing it at fairly regular intervals, there isn't any use taking back to the dealership as it's very inconvenient for me to get there.
I checked the link that had TSB's and didn't see anything for the 2010's. Also, is there any place where I could check and see when software updates come out and what issues are addressed?
Sedan - Subaru :: Transmission Downshift - Car Rev Up And Clunk As It Gradually Slowed Down
I was driving up a fairly big hill in Connecticut using cruise control (65 mph). The transmission downshifted, and the car started to rev (speedometer and tachometer) and slow down. I then felt a clunk and the car started to go again. The car kept on doing the rev up and then clunk as it gradually slowed down. Putting the car in Park caused a grinding noise, and Park did not keep the car from rolling. What did I break?

Or just can I just replace and go. I'm having some issues with trans on my 06 gs430. It's having a downshift clunk/jerk when coming to a stop. I just purchased a used trans, but would like to see if it could be ecu related. I have seen other comments from other member that they replaced the trans, but still the issues were present. Some stated that there was some issues with the ecu holding the trans solenoid longer then the usual.

I tried starting my car today and it didn't want to go. I took out the air intake sensor blew at it and plugged it back in and started it, but it didn't sound the same, the muffler wasn't making as much noise as usual and just sounded like the engine wasn't working the same. After that it started normal and i've been driving for about a week, and today it didn't want to start again so i took out the censor did the same but still didn't start so i put down the clutch revved it a couple times and like magic it worked.
I think i need to change the censor but i'm not sure and i don't want to spend money if i don't have to.
Bmw - 530 :: Battery Drain For No Apparent Reason
I own a 2003 BMW 5301 with the sports ,premium and 'M' package. Of late the battery drains for no apparent reason. This happened a few times 2 months ago and I had the battery and alternator replaced. This has again started happening. The car starts promptly in the morning but refuses to start in the evening when I am ready to leave work. It has to be jump started. This does not happen everyday and the BMW service folks have not been able to figure this out.
View 2 RepliesPassat (B5) :: Car Stuck Suddenly With No Apparent Reason
The other day, in sub zero weather I left my radio and lights on as I ran into the store to grab washer fluid. The engine was turned off, but I did leave the radio on for my buddy.... I was in the store for a max of 5 mins. I get back into the car, go to turn it back on...... and nothing.... ZERO juice.... now I've had the radio on before for a much longer period of time without the engine running and have had no problem.
We ended up jumping the car and it started up with no problem. I let it idle for a bit but then all of the light on my dash came on..... I reved the engine a bit and they all went away.
A few days pass and the car starts up with no problem. Then I get stuck sitting in underground parking, so I turn the car off while I wait for the cars to exit the garage... again listening to music with the car off... go to start and nooooo juice! Being that the car is manual I was able to get it rolling and then popped the clutch..
224,000kms and counting.... all OEM
Elantra XD (2001-06) :: Car Keeps Dying With No Apparent Reason
My aunt came to me the other day about her car not starting and I found that the battery was shot and would not accept a jump start so i replaced that and then yesterday it died again with the new battery so naturally, I replaced the alternator. After swapping the alternator I jumped the car ran it for about 20 mins and told her to follow me to grab some food. When she proceeded to back out the car died again!!!
So I tightened the belt on the alternator a little more, jumped it and let it run a little bit. This time I went through all the basic electronics lights blinkers brakes ect except ac and radio. then i back out and pull back in the parking spot and I was thinking pow it's fixed.
So I turn on the A/C and i notice the sound of the RPMs go down which doesn't concern me too much but when I looked at the RPM gauge it was erratic but the engine wasn't fluctuating with it. So I turned the ac off checked the A/C fuses they were fine. Tried turning the A/C on one more time and this time, RPM gauge stops reading all together and the A/C light was flickering very quickly.
I'm not good with the electronic side of the car but I am leaning towards a very bad grounding issue or short. I have no multi-meter so I haven't read any voltages but I am going to see if I can borrow one from my cousin.
Ram / SRT10 :: Oil Pressure Jumps From 40 To 0 For No Apparent Reason
I Have A 2001 Ram 1500 With The 318 5.2 Engine , Oil Pressure Jumps From 40 To 0 For No Apparent Reason, And Then Lifters Began To Tick. Turn Off Truck And Recrank Oil Pressure Returns To 40 Lbs, Rev Up Engine To 2000 Rpm Or Better And Pressure Goes To 0 Instantly. I Have Replaced Sending Unit, Replaced Oil Pump And Pickup, Changed Oil And Filter Using Dodge Filter, Removed Valve Covers And Intake Cleaned Out All Sludge, Tried 3 Different weights Of Oil, Cleaned Oil Passages, Inspected Oil pump Drive Shaft, Pulled Rear Main Cap And Inspected Bearing , Looked Good, Changed Oil And Filter 3 Times , Engine Is Very Clean. Engine Never Has Low Oil Pressure Either 0 Or 40 Lbs Never 10 Or 20. I Have Heard Others Describe This But Never Heard The Answer . Truck Has 70,000 Miles ,runs And Sounds Perfect When Oil Pressure Is At40. It Can Idle At 40 Lbs Hot, Which Leads Me To Believe Bearing Clearances Are Fine.

I've noticed on a few occasions (maybe 3 or 4 times total) on my 2005 V8 (about 2.5 months old and 2000 miles) that the brakes seem go into "ABS mode" for no apparent reason. No rain and no snow etc. As I depress the brake normally or even lightly it takes over and reacts like I slammed on the brakes. Then everything returns to normal.
View 5 RepliesDurango :: 2002 With 4.7 - Losing Oil Pressure For No Apparent Reason
my '02 Durango is losing oil pressure for no apparent reason. A little background here. The truck has 143,XXX miles on it, I just had the top end apart for the l/s head gasket. Everything went well, and the truck was running fine for about 3 days. Then, for no apparent reason, the oil pressure dropped off. But the weird part is, is it's not staying at zero pressure. It's actually fluctuating. Now before anyone chimes in with a bad oil sensor, you can hear the lifters start to make noise till the pressure comes back up again. Up until the head gasket, the truck had been trouble free for the past 8 years. We bought it with 55,XXX in 2005, and I've always held to 3 mo./3,000 mile oil changes, and bi-annual cooling flushes, as we go EVERYWHERE with this thing.
View 2 RepliesPrius (Gen 3) :: Check Engine Light Came On - No Apparent Reason
A month ago my check engine light came on so, after checking to ensure the gas cap was screwed on correctly, I did what the manual recommended and took my car directly to the dealership. After paying a diagnostics fee and losing my car for an entire day while they ran tests and contacted Toyota, my dealership told me they couldn't find a problem and just reset the indicator.
Within a few days the light came on again but before I had a chance to take it back to the dealership it went off. Now some 3 weeks later it is on again and I'm wondering what to do.
Alero :: 2004 Lost Power Without Apparent Reason
I have a 2004 Alero that I just bought used about a week ago. Everything has been running fine until 2 days ago..it would not start. I waited a few minutes then it started right up. Today as I am coming up the highway everything dies...ALL power to the car is gone and I coasted into a parking lot. Approximately 15 minutes my husband gets into it and it starts. The code reading machine at O'reilly says I have an evap leak but that it would not cause the car to immediately stall like that.
View 3 RepliesPassat (B5) :: Warning Messages Keeps Coming For No Apparent Reason
My wife drives a 2000 passat wagon that's had wacky electrical problems since birth...most common are warning messages for no (apparent) reason -- check engine, brakes, oil, etc...
This morning the car wouldn't start...got it going with a jump and drove it a while to recharge, but when I turned it off, the radio stayed on, as did a fan under the hood and probably other stuff I didn't notice ... I assume this is what caused the battery to die in the first place... I've disconnected it for now but can't keep doing that forever ...
I've seen a lot of Passat electrical problems, I'm guessing alternator, but don't know much about cars.
