NHTSA complaint #10509141, filed 2013-04, 100,000 miles“There is a grind/ roaring sound when I am going about 40 MPH. It definitely sounds like the transmission. I researched it on line and have determined that thousand of people like my self are experiencing the same issues, but honda has not recalled these cars. My question is does someone's transmission have to cause an accident and possibly a fatality before this issue is handled. Most people have had to have the torque converter replaced at their own expense, some after threatening lawsuits have received some assistance. What can we do?”

In the past month, I've had two occasions while in drive from a stop, when I stepped on the gas the car did not move; the engine just revved. The first time I put the car into park, shut off the car. I restarted and all was well. This next time I was going around a curve at about 10-15 MPH, when the car revving response to my pressing the gas pedal, but did not accelerate. As if it had shifted into neutral. …”
NHTSA complaint #10519366, filed 2013-06, 147,000 miles“I was told my radiator bladder exploded causing all fluids to mix, thus I now need a new radiator and a new transmission, cost of repair is $4600. My 04 MDX has 137k this should not happen, there are numerous cases of this same issue all over the internet Acura forums, why has there not been a recall on this issue, there is clearly an issue with the radiators. I need to have the radiator replaced, all fluids drained and then flushed 5-8 times to ensure all the contamination is gone, then new fluids put back in along with a replacement transmission. …”
