Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

2001 Acura MDX Owner Comments

problem #5

MDX Touring 3.5L Vtec

  • Automatic transmission

Same issues as others. Replaced Spark Plugs, 2 Coils, The EGR valve. Honda thought it might need to clean out intake, but checked and said it was fine and the EGR was to blame. Replaced that and the car is unstable. Multiple misfiring and impossible to drive. I cleaned out the intake anyway myself and it made no difference.

MDX 3.5L V6

  • Automatic transmission
  • 80,000 miles

About 3 yrs ago the check engine light came on. Brought it to Acura dealer as we have always done. They recommended we replace sparks plugs, which we did. They also recommended that we replace coils if the light came back on after that. Check engine light came back on intermittently a few months There were no noticeable problems but we had the coils replaced per Acura recommendation. Light continued coming on intermittently. Still no noticeable problems with the engine. We recently brought it back to Acura for service and expressed frustration about them being unable to find the cause and the $$ we wasted along the way.

This time they advised that found the problem - CONTAMINATED GAS. Acura service mgr had a sample of the contaminated fuel for me when I went back the next day. It was the color of orange Gatorade. I thought this was strange being that the vehicle is garaged and that we buy gas from the same few locations near our home. So, declined their offer to clean out the tank and fuel system for a cost of~$800. When I got home, I siphoned gas from the tank to find it was clean. Brought my sample back to Acura service the next day. They indicated that contamination could have come from somewhere other than the tank which is IMPOSSIBLE. BS on top of BS.

There's more but we're disgusted with this rather obvious attempt to rip us off. We'll be taking our story to Acura corp. Stay tuned...

MDX

  • Automatic transmission
  • 44,000 miles

I have a 2001 Acura MDX with VERY low miles. The car is showroom condition. A few months ago the engine light came on. I was told that it was the fuel injection system...so I had it fixed...then two weeks later the light came back on...I was told I needed the valves adjusted...so I had it done...two weeks later...same thing...battery...had it done...coil...had it done. Now the light came on again. Acura seems to have NO idea what is causing this and I'm tired of throwing money at the situation. Hopefully someone out there has had a similar situation and knows a solution!

MDX 3.5L SOHC V6 24v

  • Automatic transmission

The check engine light came on, went to Autozone for the FREE OBD2 check. Diagnosis was P0300 (Random Multiple Misfires), P0301 (Misfires Cylinder 1), P0302 (Cylinder 2), P0304, P0305, P0306. You get the gist. So far replaced spark plugs from OEM, to OEM plugs. Reset ECU, still coming up with the same codes.
