Owners report panoramic roof frame popping and creaking noises, and some say the car can be started and driven without a key inside. These issues affect comfort and security, and may be costly to diagnose.
Rear hatch windows have spontaneously shattered while parked, and windshield wipers have suddenly seized in heavy rain. Both can impair visibility and create safety risks.
Complaints include engine problems during highway driving, sometimes in wet conditions. Such failures can lead to loss of power and dangerous situations.
Multiple owners report vehicle thefts, often with evidence of forced entry at the driver-door key cylinder. This points to a vulnerability that buyers should address with anti-theft measures.

Owners report air bag deployment without impact, causing crashes and injuries, and unreleasable vehicles due to parts shortages for recalls. This is a critical safety concern.
Master cylinder brake recalls have left owners unable to get repairs because parts are unavailable. Driving with a known brake defect is risky.
Complaints include alarms going off at night, dashboard lights flickering, and cars not starting, as well as suspected unauthorized remote access. These issues can strand owners and raise security worries.
Fuel pump recalls appear multiple times, which can cause engine stalling. Owners may face delays waiting for remedy parts.
“I am submitting this complaint regarding a 2021 Acura ILX (VIN: [XXX] ) that has been unreleasable for an extended period due to manufacturer inability to supply a required safety component. The vehicle was involved in an accident on July 6, 2025 and delivere…”

Buyer analysis
Acura RDX or Acura ILX: which should you buy?
The Acura ILX has far fewer complaints per year (about 27 vs. 115 for the RDX), but it has more recalls (36 vs. 22) and a higher share of safety-critical air bag and brake issues. In practice, the RDX may have more frequent annoyances, while the ILX has fewer complaints but potentially more serious recall-related downtime.
Key differences
- The RDX has about four times as many complaints per year as the ILX, but the ILX has more recalls (36 vs. 22).
- RDX issues often involve panoramic roof noises, shattering rear windows, and theft vulnerability, while ILX problems center on air bag deployments and brake master cylinder recalls.
- The ILX has 14 injuries and 0 deaths reported; the RDX has 23 injuries and 1 death, though these numbers don't account for exposure.
- Both suffer from parts shortages for recall repairs, but the ILX's air bag and brake recalls are more directly safety-critical.
- Listen for popping or creaking from the panoramic roof over bumps, and check for any signs of rear window stress or prior shattering.
- Test the keyless start system to ensure the car cannot be started without a key fob inside, and inspect the driver-door key cylinder for forced entry damage.
- Ask for proof that the air bag and brake master cylinder recalls have been completed; parts may still be unavailable.
- Check for electrical gremlins like alarm going off randomly, flickering dashboard lights, or difficulty starting.
Before you buy
- Run the VIN on NHTSA's recall site to see if any open recalls exist, especially for air bags, brakes, or fuel pumps.
- For the RDX, test the panoramic roof, rear window, wipers, and keyless start; for the ILX, test the brakes and electrical system.
- Ask the seller for maintenance records and any recall repair paperwork.
- Have a mechanic inspect the specific components mentioned in complaints, such as the roof frame, brake master cylinder, or air bag sensors.
- Consider an anti-theft device for the RDX if you live in an area with high vehicle theft.
