Power train
87 reports2 crashes
“The contact owns a 2005 Acura MDX. The contact stated that while driving at an undisclosed speed, the vehicle jerked and failed to accelerate as intended while depressing the accelerator pedal. The VSA (Vehicle Stability Assist) warning light was illuminated. The contact pulled over to the side of the road and turned off the vehicle. The vehicle was able to restart after several attempts; however, the failure recurred after driving a short distance. The vehicle was taken to an independent mechanic, where it was diagnosed that the OG sensor and the PMP sensor needed to be replaced. The vehicle was not repaired. The contact stated that the failure had progressively worsened, and the 4WD warning light was constantly illuminated. Additionally, the contact stated that while driving at an undisclosed speed and approaching a traffic light recently, the vehicle unintendedly downshifted and nearly stalled. The vehicle was taken to an independent mechanic to be repaired for the most recent failure. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.”

“I PURCHASED THIS VEHICLE FROM A PRIVATE AUCTION IN HESPERIA, CA AROUND AUGUST OF 2020 AND I AM CURRENTLY THE REGISTERED OWNER AS OF TODAY. ABOUT A MONTH INTO THE PURCHASE I NOTICE THE CAR JERK AND BRAKE UNUSUALLY WHILE IN MOTION. I DIDN'T KNOW WHAT EXACTLY HAPPENED AT THE TIME SO I IGNORED IT FOR THE MOMENT. THEN ABOUT ANOTHER MONTH AFTER THAT INCIDENT MY WIFE, KIDS AND I WERE TRAVELING ABOUT 70 MPH ON THE 15FWY HEADED SOUTH AND THIS TIME IT HAPPENED ONCE AGAIN AND MORE AGGRESSIVELY DUE TO IS TRAVELING AT A MUCH GREATER SPEED AND DID JERK A LOT HARDER ALMOST MAKING MY WIFE LOSE CONTROL. LUCKILY SHE WAS ALERT AND PULLED OVER TO THE SHOULDER RIGHT AWAY AND THAT'S WHEN WE NOTICED A NEW LIGHT ON THE I DASH HAD ILLUMINATED. WE SEE THE ACRONYM (VSA) ILLUMINATE AND I HAD NEVER SEEN THIS PARTICULAR LIGHT BEFORE SO I THEN START TO RESEARCH IT. I FIND OUT IT'S PART OF AN ANTI LOCK FEATURE AND IT'S SUFFICE WHEN DEALING WITH CURVY ROADS AND HELPS WITH TRACTION WHICH GIVES SMOOTHER TURNS WHILE DRIVING AND GIVES BETTER CONTROL OF THE VEHICLE. I ALSO READ IT'S BEST TO KEEP THIS FEATURE OFF WHILE COMMUTING IN YOUR REGULAR EVERYDAY TRANSIT. SO AS MONTHS GO BY IT HAPPENED TO ME…”
