2018 Acura RDX Complaint Log

UNINTENDED ACCELERATION WHILE BRAKING ON MORE THAN 1 OCCASSION

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.

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.

The torque converter is defective in my 2018 Acura RDX. I have received flashing warning lights on my dashboard in Red " Check Transmission." This warning light is due to Acura's defective torque converter. The torque converter affects the shifting of power during driving and cause hesitance or shuddering when attempting to accelerate.which causes my vehicle to sometimes to have a decrease in power . This affects my safety while driving my 2018 Acura RDX. Acura is aware of this defect and safety risk. Acura Client Relations informed me that Acura was mandated by the government to provide a Warranty Extension for the 2017-2018 Torque Converter. I received one of these notices and took my car for the repair. I left my car with the dealership for 6 days. The dealership decided that they will not repair my car because they have determined my car has a "branded title." I purchased my vehicle used from an Auto Body Shop. My vehicle was declared to be salvaged. My engine/transmission/torque converter is the original on my Acura RDX. and was never damaged or repaired. My RDX torque defect should be a safety recall because it affects my safety.

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

[XXX] on [XXX], traveling 70mph on busy highway, blind spot monitoring failed, gear display failed, and check transmission message flashed across display. Had to guide car safety off road and into parking lot. This was first time ever happened. Did not know what was going on or what was happening; safety features like blind spot monitoring (especially after becoming accustomed to) failing all of sudden could have caused a major accident by inadvertently cutting someone off, decrease in speed, etc. Turned vehicle off and all lights disappeared. Had car looked at by Honda Dealership next morning; notified it was a P0741 code and failed torque converter. These systems apparently always go down with this code. Told it was associated with known issue of SB23-029 after they consulted with a local Acura dealership. They were told Acura sees this all the time and a torque converter would repair issues I had. Stuck with almost $5k repair bill for a global issue because out of mileage extended warranty. Spoke with Honda representative Naomi (claim#[XXX]) advised of situation, was asked to provide a bunch of personal information not containing to claim over nearly two weeks, and then told I was denied assistance because system wouldn't take, I was not original owner, and out of mileage. This should not be a SB; THIS NEEDS TO BE A RECALL! I'm seeking legal representation and looking at options to recover losses from Honda negligence.

About About a year ago I received notification that The fuel pump impeller was improperly moulded and this could cause the car to shut down. This could cause accidents. Well, I have called Acura and Honda dealerships a multiple times and they give me the run around. Some say wait for mail stating that I should schedule an appointment. I never received such letter. Other dealers didn’t even look up my vin number and said that the one I was giving them was wrong. It is imperative that this gets repaired because I drive about 144 miles a day Monday to Friday and Honda is not helping.

The car jerks right at 20mph in traffic every time as long as you continue to drive. When you pull over, turn the car off, restart the car the problem stops. I’ve had this problem off and on for the last two years and it’s getting worse.

I have received the recall notice from American Honda Motor company regarding the recall number 23V-858 for my Acura RDX 2018 fuel pump recall. My car had symptoms described by the recall: could not start the engine as well as losing drive power. I didn't record the exact days the incident occurred but it was early in 2024. Acura told me the fuel pump replacements were available and sent to their dealers but it was not the case. I have contact local Acura dealers in San Diego and they said they have not received the Acura RDX fuel pumps from manufacture. I also contacted the Acura dealer in Tustin where I bought the vehicle. The service manager, Jennifer Flores, told me they have never received the Acura RDX fuel pumps replacements as promised from American Honda Motor. Please help me to ask American Honda Motor why they said fuel pumps are available but none of their dealers received it. I called the American Honda Motor and they said the fuel pumps are available but dealers said otherwise. What is going on with American Honda Motor? They are putting their customer lives in jeopardy. Please help me as well as other American fellows too.

I am unable to find a dealership that will perform the repair, please help. They all say they are short or parts and are only fixing vehicles experiencing issues. I lose power when accelerating all the time but this apparently is not enough.

It is progressively getting worse where my fuel injection is not working and when trying to accelerate and merge into traffic it bogs down and i almost get hit by the car behind me.

My 2018 RDX has started to jerk when I stop and then restart. I have noticed some hesitation and a bit of jerky driving but today it was very noticeable. I could barely go above 40 miles an hour after I started driving after a stop light and the car was very jerky. It seems to be either a fuel pump or transmission issue. I am going to check with the RDX dealership where I bought the car in 2018 but I wanted to report the issue. I also looked up the VIN on my car for a recall and the system said my car had not been recalled. Not sure why my 2018 RDX is different from other 2018 RDX models that were recalled.

The car hesitates to start and while driving jerks at around 20mph. This happened a few times in the last year. When taken to dealer, because they could not reproduce incident, said it can’t be diagnosed. I told them it jerks when accelerating at around 20mph and keeps doing it every time I have to stop at light and go again.

There is acceleration hesitation every time when I'm driving. The car seems to "catch" as it's accelerating and is very "jerky". The issue has gotten worse over time. I take my care to Acura for a second time next week to see if I can get it officially diagnosed; however, I've already been told there are no parts available and I'll just be "put on a list". This recall was announced in Dec 2023 and it's now Sept 2024 so I don't understand how this delay is acceptable. The additional details that I need to provide below only allow me to enter one date. I started noticing the issue last year and as I said it's gotten progressively worse. I last drove yesterday so used that date but it's been going on for about a year.

On Thursday 27/7/2024 5:00PM-6:00PM, Acura RDX abruptly started to slow down. When I press the accelerator, the car will not accelerate. Finally, my car came to an complete stop. Then I turned on Hazard sign and changed the gear on P from D. After that I started car. The car started normally and then I drove to my destination. I also experienced the similar issue in May, 2024.

I had minor accident on [XXX] in my 2018 Acura RDX. The front crash sensor was damaged, so the car cannot be returned to me without a new one because the air bags and other safety equipment will not deploy in front crash. The repair shop ordered the part (no. 77930-TX4-A11) from Acura on 5/28, along with other parts needed. Acura's delivery date for this part has changed from 6/24, to 7/2, to 7/11, and 7/18. However, my Acura dealer indicates they've had this part on order since April, and Acura has provided no estimated delivery date. I filed a claim directly with Acura a week ago (case no. XXXX), demanding that they provide me with a comparable vehicle until they can provide this part, and no one has even returned my calls. American Honda is in violation of federal law, which requires companies that sell automobiles in the US to provide parts for them for 10 years from the date of manufacture, and to compensate consumers for failure to do so.

Im writing to let you know that Acura is saying that this replacement part is not available until Fall 2024! This seems to be quite a long time to wait for a part that if not replaced poses a severe safety issue.

On [XXX] while traveling around 70 mph on [XXX] approximately 30 miles south of Florence, SC, I heard vehicle glass explode. The loud pop nearly caused my wife, driving at the time, to veer violently to the left lane. I requested her to pull over slowly so I could determine what happened. I looked around the entire vehicle and finally found the sunroof glass had imploded. There were no vehicles around us at the time of the implosion and we didn't see or hear any objects hit the vehicle (i.e. rock). Also, I looked over the entire vehicle to see if a rock impact or something had hit the car, but couldn't find any evidence of an impact by an object. This is a severe defect and should be considered for safety recall. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Received a recall notice in December 2023 about the fuel Acura Fuel Pump Motor Recall. Since then I have received several notices from Acura but the parts are not available when I contact the dealership to schedule service. They claim the parts have not been made available to the dealerships. However the OEM part is available for purchase from several parts suppliers. This is not acceptable.

Unintended acceleration, hesitation, and transmission issues. When accelerating from first gear to second gear, hesitates and then suddenly lurching forward.

My car lurches when I put it into gear, drive or reverse. When a red light turns green and I put my foot on the accelerator the car will lurch forward. I was in my garage when I started my car and my foot was firmly on the brake as I shifted into reverse with my foot on the brake the car violently lurched backwards.

Vehicle began hesitating when starting, but not all of the time. One day after refueling it would not start. Lights on the dashboard flashed and flickered and the keyless start button made a clicking sound, but the vehicle would not start. Vehicle was towed to the nearest mechanic. The next morning the mechanic started the vehicle and found nothing wrong. Mechanic kept the vehicle for a couple days and the problem reoccurred. Vehicle will not start. Computer diagnostics shows the 2018 Acura RDX Control Unit part number 38320-TX4-A31 is faulty. This part is backordered and likely will not be available in the near future. The intermittent starting failure poses a safety risk and could leave a driver stranded.

Not sure where to direct this, so please redirect if this is the wrong inbox.  I recently went into a local service appointment to have our passenger seat belt buckle replaced at Acura Concord.  We had noticed that the belt was not seating securely in the buckle, and could be removed with minimal-to-moderate effort (would guess 15-30 lbs of force) - certainly not safe in a collision.  It started to stick intermittently, and slowly got worse over time until it got to a point that it was clearly unsafe. We were concerned and I proactively paid to have it replaced.  The service technicians suspected that something might have entered the belt and was preventing the mechanism of working correctly.  However, upon replacing the buckle, the service technician reported that the belt buckle had no foreign objects inside it, and appears to have been mechanically failing. This was alarming, and I quickly searched online to find the current seatbelt recall.  However, my vehicle is not a part of that, but maybe should be given the technician's findings.  The technician's report can be found through Acura of Concord, and has a reference number of RO#203423 / Tag# 172B. I asked the technician for the faulty belt and currently have it in my possession (pictures of it sticking are attached, this is the first and only time I've touched it since the appointment).   Please let us know, we'd like to make sure these vehicles are as safe as they can be for all purchasers.  Appreciate your time and attention here.
