What owners report

All wearing seatbelts. 1 serious and 3 minor injuries. Car completely totalled. No drugs or alcohol involved.
For some time now I have felt my brakes do not perform up to par. Recently, in stop and go traffic, I was unable to stop on time when a vehicle in front of me slammed on their brakes. I bumped the other driver in the rear of their car and now it is costing me a surcharge on my insurance.
Tl* the contact owns 2003 acura rsx. The contact stated that the vehicle spontaneously accelerated without warning. The only way the contact could stop the failure was by shifting into park and braking. The vehicle was taken to the dealer where the contact was awaiting diagnosis of the failure.
When trying to shift into 2nd gear it grinds and pops out. It is so bad that now it will not allow you to put it in 2nd at all. Synchros are bad...common problem with rsx. Acura should be forced to fix this issue since it is so common in these vehicles.
The vehicle then stalled without warning and shortly after, he was able to restart the vehicle. Once the vehicle was restarted, the vehicle abnormally accelerated and increased in engine rpms of 9,000. He was able to put the vehicle into neutral and maneuver off the highway.
Srs light on my 2003 acura rsx, car only has 80,000 miles. Dealer (st louis acura) says that it is not covered under the nhtsa # because it is a different part. Although this part (srs unit) works with the opds they say it is not covered.
2003 acura rsx. Accelerates for no reason, without pushing on the throttle pedal. This usually occurs after the vehicle has first started, and about 30-60 seconds after starting. This is an on-going problem for the past 10 months.
She stated that the airbag srs light remains illuminated at all times. The srs light was inspected and reset however, the problem continued to occur. The contact also stated that the opds unit needed to be replaced. The failure mileage was 65,000 and the current mileage was 80,000.
