#2688 of 3016 Re: high altitude looses power [kimco59] by Mr_Shiftright HOST Sep 22, 2008 (7:36 am)
Replying to: kimco59 (Sep 21, 2008 9:16 pm) Has anyone hooked up a gauge to the fuel rail and checked the fuel pressure. You could have a bad fuel pressure regulator. Will this problem happen on the level at high altitude or only uphill. If the latter, one might suspect a gas tank issue or fuel filter issue.
#2689 of 3016 thank you mr. shiftright by kimco59 Sep 22, 2008 (8:12 am)
thank you for responding. we truly are stumped. dealer not in helpful mood. a friend drove with his scanner hooked up when it happened outside of flagstaff he said it was running leaner and leaner til it totally lost fuel altogether then dumped alot of fuel after loosing power. happens going up hill in high altitudes. we live in nm going up and down hills no problems until clines corners, raton pass ,colorado springs, flagstaff all high altitudes and in same spot every time.

Replying to: caruso1 (Jul 12, 2005 8:04 am) My 2002 Hyundai Sonata was having the same problem (working fine until it randomly wouldn't start--all lights, AC, radio, and power windows would work fine but there would be no sound or movement under the hood at all... and then at random it would work fine again).   My mechanic thought it was the starter so I had it replaced. It was fine until a week later when it happened again. My mechanic was kind of confused and spent a day and a half looking over my car and trying to get it to mess up when it was with him. Finally, my car messed up with him there.   After digging around in my car for 5 hours, my mechanice found a loose ground wire to the starter relay and/or to the alarm system. Once he fixed that, it worked fine.   Maybe this is the solution to your problem too... Replies to this message: sunkleep (Sep 24, 2008 9:32 am)

Replying to: rwolking (Sep 23, 2008 2:50 pm) My wife's 2002 had the same problem (randomly not starting)... I narrowed the problem to the alarm/anti-theft system (never found the exact problem), but we resolved the issue by having a remote starter system installed (professionally) and have never had the problem since -- the remote starter system deactivates the alarm and hence solved the intermittent starting issues.

Replying to: jayess (Aug 21, 2008 2:54 pm) Kudos to my 'service guy' Bob at Cochran Hyundai Monroeville PA - eastern suburbs outside of Pittsburgh. After pondering the rear brake issue (8/21/08 post #2649), I decided that I needed to pursue this up the ladder - rear brakes at 18.6K miles being neither normal or acceptable and offered him the opportunity to advocate on my behalf before I started with HMA customer service. He called me back about two weeks later to say that Hyundai had decided to authorize it as a warranty repair despite the mileage and 18 months that we had the car and that a refund for my out of pocket - brakes and turned rotors - was forthcoming. Only needed one followup call a week later to remind them to put it in the mail. We received today a refund check, in full, for the brake job. We're satisfied
#2693 of 3016 Re: Hyundai Sonata update [fannibal] by gretchenlb Oct 20, 2008 (6:58 am)
Replying to: fannibal (Mar 28, 2008 1:23 pm) According to the dealership(I have the same car and problem), it's what they like to refer to it as a "characteristic" of the car. That explanation did nothing but infuriate me!! The service manager told me that it's typical in the 4 speeds. But guess what the 09 Sonata is...5 speed!!
#2694 of 3016 CAR MICE by tomw6 Oct 20, 2008 (12:31 pm)
Asked this question a few months ago. No one could or would answer. Please help if you can. Mice continually nest on top of the cabin air filter in my 06 Sonata. I've removed nests, poop, dead mice (oh, the smell) and even a dead litter of 5. About 9 different times. I suspect they've marked a "trail" into the cleaner. I would like to know where the air intake for the cabin air is so that I can put a metal screen or ... over it. Help, please. (I've phoned and/or visited 3 dealers. None of them can/will tell me - a bit surprising of itself. I've tried online with no luck. I set traps on the engine cowling at night and have caught several, but still they come. And you may know that cabin air filters, simple and small though they are, are not cheap. HELP, please. Replies to this message: pat (Oct 20, 2008 1:13 pm)

#2696 of 3016 Trans Flush & Timing Belt replacement by de1029 Oct 24, 2008 (7:06 am)
Car is 2000 Hyundai Sonata V-6. Currently at 110,000 miles and sensing possible trans slippage...car appears to be mimicking Engine Light...speed sensor behavior but less balky. Make sense? At 105,000 trans fluid should be addressed per maintenance manual. Is the trans flush NEEDED (overdue) and that is why I hear the hum/whine and sense the occasional slippage? At last maintenance - rear hub assembly, repair shop said I needed Trans Flush - Standard (approx. $90.00). When in Neutral or Park...I do not hear enging noise (aka...hum which appears to have gotten louder...tired of raising the radio volume!!) When in drive I hear the sound, hum, whine. Any ideas? Also, Since timing belt needs replacement REAL SOON (at 120,000 miles and I think I did the first replacement about 5000 mileas EARLY...so, it is DUE!)...should I do both at the same time...the timing belt is a lot of labor, so I understand, and expensive...so, do together...or...IS THERE SOMETHING ELSE MORE SERIOUSLY WRONG and I should start looking for a new car? As always...I rely on your wisdom and experience...to assist me in making my move.

Replying to: de1029 (Oct 24, 2008 7:06 am) Are there codes that were found? What were they?   Well sure a transmission service is a lot cheaper than a new transmission. I'd do that right away and see how the symptoms go. Also have the trans. codes read. It might only be some kind of shifting solenoid. If it's a stuck valve in the valve body then perhaps a service would help. You could also try some Sea Foam transmission additive. I think it's called Trans Tune. But you need the service, ,too.   Visiting Host Replies to this message: newowner10 (Oct 24, 2008 10:32 am) de1029 (Oct 24, 2008 10:53 am) de1029 (Oct 24, 2008 10:50 am) Mr_Shiftright (Oct 24, 2008 1:23 pm) de1029 (Oct 27, 2008 8:12 am)
