Acura - Mdx :: 2007 - Clunking When Go Over Sharp Bumps / Check Emissions Light Came On
Jan 12, 2014
Problem #1: So I've noticed a clunking when I go over sharp bumps or uneven road conditions (think roots under the pavement) at low speeds, such as in a parking lot. The noise is only under the front left tire well area, and the car drives smooth and great otherwise. Is it a bad joint? The closest dealership is over an hour away, so I want to make sure I'm driving there with a real reason. The MDX has about 130K, transmission is great, and new timing belt, so I'm scared it's some sort of axle/joint problem...
Problem #2: The check emissions light came on about two days ago. I have filled up since, but it hasn't gone away. There is not a smell from the exhaust, and there is no rattling. Gas mileage hasn't changed one bit either! What could it be?? The car has been restarted quite a few times, but the light comes on each time.

I have a new to me 07 MDX with 82k miles. Exactly at 1 mile over the 30day/1200 mile used car warranty the Check Engine Light illuminated along. The NAV screen showed an emissions code P0401. I really don't notice any symptoms in running at all. Anyway a few drives (on/off) and it turns off for four days. It happened again with same code. Again few drives it went off. It seems to happen when driving easy. It gets great MPG in mixed driving on average (20MPG) which is far better than its rating. Should I wait till it stays on steady before I address this?

I know lots of you say these stock Rancho's suck, but I'm wondering if it's just the ride that improves? I have some clunking under the truck when I go over "sharp" bumps that normally I would say is something loose or maybe a bad ball joint...except I have it in the rear as well. Is that a symptom of these stock ranchos? I don't mind the stiff ride, it's the noise that's bothering me.

The "emissions" light on the dash of my 2002 Acura RSX lights up when I run the heater in winter months. It only comes on when the heater is on. It is never on in the summer, and even when it is warmer outside and I have the heater on, it will turn off. The gas cap is not loose, and the car is otherwise in great condition. Is this something I need to worry about?

2004 Acura MDX, check engine light came on. Got code checked: P0741, supposed to be switch or torque converter. My mechanic won't do transmission work, so took to dealer. They drained fluid, no metal shavings. Now they want to replace transmission, said it has internal damage. It wasn't running badly, a little slippage here and there. Don't think it really needs replaced.

I have Acura 1996 3.2 and its a great car but about 2 months ago the Check engine light is on and when i try to accelerate on highway or just on high speed it wont go in the next gear at the moment but when I am gonna press the pedal harder suddenly it will accelerate in a second. Also when I am standing on the traffic light the dashboard starts shaking and its a feeling like a car is going to turn off. Its an automatic. And this happens more frequently when the tank is full.

Took my 2010 with 10,250 miles to the Dealer yesterday because there is an uncomfortable "tinny" rattle heard under the car when driven over sharp bumps and dips (rough road). Almost like a loose brake shield. At oil change I made mention of this and a missing fastener and nut clip was thought responsible. This time I had a test drive with the mechanic and we verified it was on both sides having done several passes on the same road hazard. After a period of trouble shooting in the shop, a decision was made on the front struts, but none in stock. Brought it back this morning for the replacements and was found not to be the problem.
This is one of those noises you can duplicate on the road, but not easily in the shop. Have had no accidents or run overs, and the car is in perfect condition otherwise. It is not the oil door.

I am experiencing issues with front shocks RS2 Coilovers. I have this knock occurring from both front shocks. If they're set the softest, they're the worst...knocking noises over all small sharp bumps or sharp dips in the road. If I set them to full stiff and you drive it immediately after the ride is stiffer, but smoother, almost no noise at all, only when driving over roads that throw weight from side to side quickly will create the knock, but very light. However after a while of driving it just starts to make noise again as if they're unwinding on there own. When I check their position, they're where I left them. It feels as if the shock pressure bleeds until I perform the same routine and it feels tight again for a short period.
Its starting to annoy me now, car has 6000km on it and 600 km on the coilovers.

What this clunk could be?? in my truck in signature, 2003 F350 CCLB 4x4, 4" lift. its only low speed, on very light bumps. really does it when the truck flexes, like turning into an elevated driveway or something. driving me absolutely insane the last few months. it sounds like its coming from right under my feet
-removed front shocks and drove
-removed front sway bar and drove
-front wheel bearings are new and tight
-front leaf spring, rear upper shackle bushings are new (thought that was problem..no)
-front leaf springs and bushings are new, although i suppose its possible to have a bad bushing already
-removed traction bars and drove
-removed front track bar and drove, but going to try this again.
-all cab mounts look ok
-took out cab mount under drivers foot, and cut down the metal piece a little...read about it on another thread on here. no change
-made sure my gooseneck ball couldn't rattle
-steering box is new...thought that was it
-steering shaft is solid
-transmission mount bushing and crossmember feel tight
-lubed front driveshaft slip joint and it doesn't have any u joint play
-rear shocks seem ok but haven't removed them yet
-fuel tank is solid
-rear driveshaft has new carrier bearing and u joints, all is tight
-exhaust is not hitting anything
-u bolts all tight, spring bolts are tight
As you can see, I've been through damn near everything. my only thoughts right now is a possible bad cab bushing, or bad leaf spring bushing...as it sounds like its right under my feet. and when you flex the truck, it makes all sort of popping and clunking noises. i had the truck on my buddies lift and we went under it for an hour yesterday looking around with no luck. only thing i found was a bad traction bar bushing but we removed them and it still does it..
Most noticeable at the end of the video...it sounds exactly like a bad sway bar bushing but that's not it...

The check engine light on my 1997 Integra (LS, 119K miles) has come on for the second time. Including background below.
Incident #1: Carin mid-June, the car sputtered or shook a bit when starting and the check engine light came on.The car had been sitting in the garage only about a day. Codes were P0303 (Cyl 3), 0304 (Cyl 4), P1399 (multiple misfire), P1300 (random Cyl misfiring). The p0303 code set at 1600 rpm & at 75F degrees. Misfire code set during warm-up. The shop performed block test (came negative). Compression tests show 1, 2, 4 at 200 psi & 3 at 190 psi. The shop replaced spark plugs & inspected plug wires & connectors as well. Valve clearance adjustments also were done. The shop cleared the engine light code.
Incident #2: Last week (early Aug), the car again sputtered & shook when trying to start (had been sitting in the garage for about 2.5 days). Showed signs of low or dead battery but started after cranking a few times. The check engine light came on again. Codes (checked at home using the jump method) indicate Cyl 1 & 3 misfire.
Will be taking to the shop for the diagnosis again but wondering if it is battery or ignition related; shop doesn't suspect the battery, however, I do sense that the battery 'feels' weak esp. when starting. New battery put in May. What could be going on?

I have the 2012 Touareg with adaptive head and LED accent lights. I have observed that when the road has sharp bumps and you are going slow enough to observe your light pattern on the ground, the lights, the LEDs I believe, appear to be "Jiggling". I realize there must be a more technical term for it but I would think from the oncoming traffic the appearance would be reminiscent of the old motorcycle light heads that were never very tight and would appear to bounce or "Jiggle" up and down as they approached. The dealership says they all do it and it is because the LEDS are mounted in plastic and the plastic is vibrating.

I've had a clinking sound at the front of my car when driving over sharp bumps like seams or cracks ever since about 6k miles. I only notice it with the windows down. I used to think that it was the coils on my Nuespeed sport springs hitting each other, but after I got coilovers and the noise didn't change I was sure that it wasn't the springs. When talking to my mechanic on the phone he suggested that I see if the problem goes away if I apply the brakes when driving over something that causes the noise, and sure enough the noise isn't there when braking.

When I'm driving over sharp bumps I hear what sounds like a small chain jingling around. I took off the hubcaps and jacked up the car to see if anything loose. I grabbed the exhaust pipe and shook it, but it didn't make any noise. I couldn't see anything that would cause it. The front right strut's rubber cover is off so could the strut make that noise?
I just read a few posts with similar problems, but one was a compression sound and another was a knock, and another was a metallic hick up. Mine is literally like a loose high pitch chain noise and change rattling in your pocket. No uniformity to the sound. But it also only happens over quick small bumps not large ones like speed bumps.

For the last few weeks, when I make a turn (particularly a sharp turn in either direction) I get a "clunking" noise that sounds like it is coming from the front end somewhere. I can also feel it - almost like a gear slipping and engaging again. I am not in 4WD mode when this is happening. It NEVER happens unless I am turning a corner. If I drive straight, it's fine. 1999 Explorer XLT (4 door, 4wd model)....

09 stx 2wd 4.6L- I have a 2.5'' leveling kit and 33'' bfg a/t tires. The problem is when I make sharp turns, or turn and go over small bumps. Whats happening is something seems to catching or rubbing it kind of jerks towards the opposite of where I am turning and causes the traction control to slow my truck (sucks on tight off-ramps/ u-turns). this happens at pretty much any speed although it gets worse as speed increases. At first I thought it was the steering stoppers but don't have any wear on them, tires do not rub anywhere. My dealer and a local off road shop cant figure it out...

Alright I've got an 09 camry le on 18's, I recently just put the tein s tech springs on and since day one it clunks when I hit bumps. I did the install myself (not bad, just time consuming), so no taking it back to someone. I've taken the wheels off and made sure the bolts are all tight and the top mount too. Everything is snug. Still clunks. Is this just something that is normal with aftermarket springs on stock suspension?
