Silverado :: Instrument Cluster And Radio Lights Flickering / Surging
I have a 99 silverado, 5.3l Z71. This morning got in my truck, it started up fine, I then noticed instrument cluster and radio lights were flickering/surging but voltage was at 14v. Put it in reverse and the voltage dopped to about 12/13v like it was about to die gave it gas and it shot back up to normal. So I'm driving and everything electrical goes out and comes back on. Battery flashes, security light flashes, abs brakes come on and off, gauges fluctuate. And noticed it was doing it every 4 seconds. Radio doesnt stay on after i turn the truck off either as it normally does. Doesn't do any of that while sitting idle only while driving and my truck never actually stops running which doesn't make me think alternator is going bad.

I got the aftermarket lights through Yefeng, with quad HIDS. So after a while, Cluster lights, Vanity mirror lights, tail lights, cabin roof lights all started to flicker or strobe faintly. Very noticeable either when lights are on or off, drive or park.
Car has less than 12k miles.
I've been driving it like that with no problems. Except one morning before I left to work, car wouldn't start. (Happened randomly) Battery is good, alternator is good. Could something be pulling power from the alternator? I have no clue.
Volvo - S40 :: 2007 - Hard To Start When Cold / Headlights And Interior Lights Flickering
I've had my '07 Volvo S40 2.4i for almost a year. It has a little over 60K miles on it and is serviced regularly. Within the last 3 months, I've noticed some weird things happening occasionally:
-Trouble starting when cold (I understand this is pretty common with a lot of cars.)
-Headlights & interior lights flickering
-Going over "bumps" in road causing dash display lights to illuminate for a second, radio to shut off, and loud system "BEEP" comes through the speakers (this has happened 3 times total, all on the same day.)
-AC stops cooling periodically I've had the system scanned for the AC issue and it seems that there was a "Pump pressure" message that cleared itself at one point and am guessing the same thing has happened the next few times it's done this.
I also asked that the battery be checked to see if it needed to be replaced soon. The mechanic said the battery was fine and thinks it's something wrong with the entire electrical system.
Sonata I45 (YF - 2011+) :: Flickering Headlights And Interior Lights Occasionally
I recently purchased a 2011 Sonata GLS and I love it. However, I'm having a slight electrical issue.
While driving at night with the headlights on occasionally they'll dim and flicker and often cut off completely while driving or parked. The interior and dash lights will also switch off with the headlights, however the radio will still continue to play. The lights only stay off for a second and then come back on. Sometimes I can make them flicker and go off by turning on my blinker or switching between high and low beams.
I'm trying to figure out if it's a problem with the alternator, the battery, or the fuses and if this is a known issue.
Sonata NF (2006-10) :: Engine Clatter Loudly When Starting
My 2007 V6 Sonata Has a very loud clatter when I start it. It will last anywhere from 2-5 seconds then it usually goes away. It almost sounds like a baseball card hitting the spokes of a bicycle. It's within warranty and last time I took it to the dealer they first claimed they couldn't hear it. Then they changed their story and said that it was the belts warming up, and they said this is a perfectly normal sound for Hyundais to make. My fiance's family has owned 3 Hyundais and they have never had such noise come from any of there vehicles. Both of my other cars never sound like this.

Is there a replaceable bulb for the check engine light? Mines stop coming on when starting the car. I think that's why I failed the emissions test. I didn't check with the attendant in the office to get an explanation.

I recently bought a 2006 sonata with the 2.4 & automatic. It has 56k miles but is out of warranty (CDN). A lot of times at 50 mph it has a very noticeable surge where the car is not sure what gear it wants to be in (feels like torque converter locking & unlocking). At 60 mph plus it's fine & the tranny shifts smoothly. The fluid is nice & red with no burning smell.
View 6 RepliesSonata NF (2006-10) :: Headlights / Interior Lighting Flickering
Past week I have noticed a flicker on all lighting (head/taillights, interior lights) on my '06 Sonata (4cyl). Seems to be an intermittent problem, as one time in three there is no flicker, and everything seems to be fine.
Yesterday, when pulling into my driveway, I momentarily lost all lighting/radio/fan for what seemed to me a full second and a half before everything "came back on".
I've checked fuses, battery cables (batty is new, 6mos)... Is this alternator related? What else should I be looking at? My Sonata has been bulletproof. No mechanical issues whatsoever....
Sonata NF (2006-10) :: V6 Idling Erratically (revving And Slowing) After Starting A Cold Engine
My 09 Sonata LTD V6 was sometimes idling erratically (revving and slowing) after starting a cold engine. It never happened in the previous 3 winters I have owned it. I took it to the dealer for service and they said an ECM update was just released, described on the invoice as "TSB 10FL002 FOR COLD START ROUGH IDLE".
View 2 RepliesSonata NF (2006-10) :: Hard Downshift When Engine Was Cold And Under 30 Mph
My car also had the hard downshift when engine was cold and under 30mph. I seen where Sbr 711 had posted the TSB 10-AT-007-1
I printed this and took to the local dealer & also showed where it was mentioned as a recall.. The advisor looked up on his computer and showed no recalls for the 09 sonata?
I went ahead and scheduled the reprogram update and was told the technician can pull up more info on recalls than the advisor can? Any way they did the reprogram today and $89. later still no recall? How do I prove that in fact this is a recall & get refunded?
Sonata NF (2006-10) :: Transmission Letters On The Dash Rapidly Flickering
Randomly for the past couple of weeks, my 2009 2.4 automatic has the transmission letters on the dash rapidly flickering... ex.: driving in D, the display flickers D-P-D-P or D-N-D-N etc very fast. It's not happening in Tiptronic mode and the car is driving very well with excellent mileage.
From what i can see, this happens when the car is in motion only. My thought is a bad contact at a sensor somewhere that loses contact on and off with bumps in the road, but not when stopped? The car has only 50,000km.
It is still under extended warranty, therefore a 50$ deductible for any repair under warranty... whatever issue i had with this car was always intermittent so the dealer won't fix anything if they cannot see the issue and have the nasty habit of charging me like a half hour for trying to diagnose without success. Guess what happens every time I drop off at the dealer? issue not present of course.
Sonata NF (2006-10) :: Surging While Driving Under Light Throttle
My recently acquired '07 SE V6 has a little quirk when I drive it in the morning. Until it warms up completely, it seems to have a little surge while driving under light throttle. Tach doesn't jumo, and there is no CEL. Tranny was just flushed and serviced also. Once the car is at normal operating temp, all is well. I've searched the archives, and there are some suggestions about having a bad TPS, but my rpm fluctuations aren't that bad, and like I said, don't make the tach move. It also will sometimes hesitate just a hair when taking off for the first time after starting.

I have 2010 Sonata with 4 cylinder engine and 50,000 miles. For a while now, my car has a real hard downshift at around 20mph. When i put the car in shiftronics mode and do not downshift manually, at the 20mph hard downshift the car is shifting from 4th to 3rd. A while back i had the TSB for hard downshift and also did a tranny fluid flush. Neither has seemed to solve the problem.
Also, the car has a annoying electrical hum/whine that is coming from the engine bay. When i shift car into neutral the hum/whine goes away. Also sometimes when shifting into lower gears the hum/whine will go away for a short period of time.
Sonata NF (2006-10) :: Battery Light Flickering For Just A Fraction Of Second At Irregular Intervals
2009 3.3 GLS ... Yesterday my wife told me that the battery light in her Sonata was flickering for just a fraction of a second at a time at irregular intervals. Nothing else was an issue so we didn't think much of it, started fine, no other lights.
She just called me to tell me that on her way into work it started very hard, all the lights on the dash were flashing, the engine was stumbling and wanting to quit, and the radio is no longer working.
It will be several hours until I can get to it to check it out, but my first thought is to check the grounds. I haven't worked on this vehicle in the past so exactly where to look first or any other issues I should look for...
Lexus GS 2006-11 :: Seatbelt And Airbag Lights Keep Flickering On And Off
Just recently bought the car a month ago. This car has been giving me a lot of headaches. First my radio unit wouldn't work properly. Just started my car today and my gauges are flickering. Seatbelt and airbag keep flickering on and off. AC says 32.0 temp and wont let me adjust it. Passenger windows don't work. Driver window goes up and down but isn't automatic anymore. I have to hold it both ways.

When coming to a stop in my 2007 Hyundai Sonata GLS with a 2.4 4 cyl engine all of a sudden you get something that acts like the car is jerking or surging or rough idling or something. Hard to tell exactly which but if I put it in neutral and rev the engine a little it smooths out. Only happens when coming to a stop. What caused it?
