All sound warnings are very low and impossible to hear them especially with the music on. The volume is very low and will not override the music volume. The warning volume is very low and driver canât increase the volume. Especially the blind spot warning on the right side, if you miss it, itâs an accident sure to happen. Acura can change this with a simple software update but they keep ignore my requests. Hopefully you, the consumer advocate, can convince them to do the software update. Letâs make it safer for all and save some lives.
Other mileage not reported 1.1 yr in service
Driving on the highway and suddenly the moonroof imploded. Luckily no other cars nearby and did not go through an underpass when this occurred. No signs of any impact to cause this from remaining glass. Waiting for Acura dealership to assess damage but told me the part was backordered due to this happening with multiple vehicles.
Engine mileage not reported 9 mo in service
I was driving in the rain, accelerated to pass a vehicle and the engine lost power. The check engine light came on and the car went into "limp" mode. The car would barely go 40 mph on a highway and the speed seemed to be continuing to decrease. Luckily I was able to pull over and shut the car off. Restarted, the problem appeared to go away. This is a very dangerous situation and I have read other people reporting similar incidents.
