Multiple lights appear turn on and off indicated on dashboard, VGA, check engine light, and tire pressure system. I run a diagnostics and it says my Evap System had a code telling me to replace gas cap. I went to the auto parts store and purchased a new gas cap that is specifically for my vehicle. I turn the vehicle back on and code is still on. So I get the code erased with my diagnostic reader and the sensor turns off. But give it a few weeks and that light turns back with same code telling me to replace gas cap. I went back to return my gas cap at AutoZone. Then ordered an OEM gas cap for my vehicle and erased code and then code came back less than a month later. It can’t be two brand new parts, one was a universal part but specific to my vehicle. And second part was OEM specifically for my vehicle and from Acura/Honda parts department. So I don’t know what to do because repair said its a dumb code and just reset if I already replaced once. And don’t worry about the code indicator because the Evap system appears to be working. So it’s either an electrical issue or a glitch. I’m not comfortable with those options

Electrical system: ignition: switch
- What is wrong
- Honda is recalling certain model year 2003 and 2004 Pilot and Odyssey and 2003 through 2006 Acura MDX passenger vehicles manufactured from November 26, 2001, through August 30, 2006. The interlock lever of the ignition switch may deform, which can allow the interlock function of a vehicle with an automatic transmission to be defeated.
- Risk
- Removal of the ignition key when the gear selector of a vehicle with an automatic transmission has not been shifted to the park position can allow the vehicle to roll away, increasing the risk of a crash.
- Remedy
- Honda will notify owners and instruct them to take their vehicle to a Honda or Acura dealer. The dealer will install an updated shift interlock lever and, if necessary, replace any necessary part of the ignition switch, free of charge. The recall began on February 22, 2013. Owners may contact Honda at 1‑800‑999‑1009.

What 2004 Acura MDX owners say
Most recent owner complaints, unedited.
Takata recall my airbags were replaced twice already through recall repair and the airbag sensor came back on last week, moment it came on I was in motion and the steering wheel I was not able to control the steering. This resulted in me side-swiping and object, hitting the curb and flattening my tire. There is also another recall on my vehicle
The airbag light warning continues to come on and stay on. Sometimes is goes off, but comes back on later. This was reported to the dealer in charge of airbag recall and the only solution offered was paying a hefty fee to diagnose the issue without guarantee. This was reported in 2014 and has been an ongoing problem before this and currently, 2019.
Hose connection failure between radiator and transmission cooler causing radiator fluid to mix with tranny fluid with no dash indicator of problem.. In motion lost power and would not move from 1st gear. Broke down completely in need of transmission work and new coolant system due to hose connect failure.
Electrical short
The seat warmer was on, and became o hot that it burned a hole through the padding and the leather, about 2 1/2 inches by 1 inch. Fuse is removed, but now have no seat warmer on the driver side, and I am intimidated to have a passenger use the seat warmer on the passenger side. Photo attached.
Transmission failed today 123k. Called customer service what a joke. Emissions light on and air bags are faulty. What a lemon. Nevet buy acura. On a city street car just down shifted and stopped. Needless to say it was 20 degree's outside. Acura doesnt see thus as a safety hazard? Confused and mad really mad. I cant believe they are still getting away with this. I've had my fill with foreign junk. I froze walking home think I have frost bite on my fingers.
