2018 ACURA RDX — Problems, Recalls & Safety Data

UNINTENDED ACCELERATION WHILE BRAKING ON MORE THAN 1 OCCASSION

I am submitting this complaint regarding a serious transmission defect on my 2018 Acura RDX that materially worsened after an Acura-authorized warranty repair addressing a known torque converter defect. Acura issued a warranty extension / service campaign for the torque converter on certain 2017–2018 RDX vehicles. Prior to this repair, my vehicle did not exhibit any severe jerking, slipping, or unsafe shifting behavior. After the Acura dealer replaced the torque converter under this program, the vehicle immediately began experiencing violent and unpredictable jerking during gear changes, worsening over time. These behaviors create an unsafe driving condition, particularly in stop-and-go traffic, intersections, and merging situations. I returned the vehicle to the dealer multiple times after the repair. As the problem worsened, I provided video documentation clearly showing the abnormal transmission behavior. After further evaluation, the dealer acknowledged the issue and determined that the transmission requires replacement. Acura Corporate declined coverage, stating the vehicle was no longer under standard warranty, despite: -The issue beginning immediately after Acura’s warranty repair -The torque converter being an integral component of the transmission system -The vehicle being in a worse and unsafe condition after Acura’s work I am requesting that NHTSA: -Review whether Acura’s torque converter warranty extension repair fails to adequately address associated transmission damage -Determine whether Acura vehicles repaired under this program are being returned to consumers in an unsafe operating condition -Assess whether Acura is improperly denying responsibility for post-repair transmission failures directly related to related to the covered defect

The vehicle has developed a serious transmission defect involving harsh shifting, delayed engagement, and repeated slipping into neutral while driving. Since picking the vehicle up from Key Acura after an inspection, the condition has worsened significantly. The “Check Engine” light, the flashing “D” indicator, and the transmission warning light are now consistently illuminated. Prior to the dealer visit, these warning lights were intermittent; they are now on at all times. The vehicle can unexpectedly lose propulsion or fail to accelerate, which creates a safety risk during normal driving, especially when merging, crossing intersections, or turning. The symptoms are consistent with the known torque converter and transmission issues documented in Acura Service Bulletin 23‑029, which applies to 2017–2018 RDX models. The dealer inspected the vehicle but did not perform repairs, and the drivability and safety concerns have become more severe since the visit. Acura/Honda Client Relations has been contacted and a case is open, but no resolution has been provided. This defect poses a significant safety concern due to the sudden loss of power while the vehicle is in motion.

I have been experiencing unintended acceleration when I press on my brakes. Fortunately, there hasn't been any accidents yet but it's a very dangerous situation.

My car's original security alarm goes off randomly without any reason. When parked and locked in a parking lot next to a street, the alarm goes off intermittently. After unlocking using FOB, the alarm will turn off and then goes off again in a few minutes. This will go on for hours at a time until it stops for a few days and then reoccurs again! Very stressful and frustrating. The mechanic says it's caused by faulty Body Control Module and will cost over $1,000 to fix. I see that many people are having the same issue and have to pay over $1,000 to repair. This faulty reequipment should be recalled so owners can recoup their damage.
