What actually goes wrong
The problems owners report
The most-complained-about systems on each vehicle — what fails, and what owners say in their own words.

Owners report unintended acceleration leading to crashes, such as a 2025 RX 350 suddenly accelerating into a brick wall. Others say the rear seat belt reminder fails to alert, even though the manual says it should. These are safety-critical because they can lead to injuries or make it harder to secure passengers.
Many complaints describe a parasitic 12-volt battery drain that leaves the vehicle dead after sitting, sometimes within weeks of purchase. One owner reported the battery dying at 120 miles. This can strand you and require repeated jump-starts or dealer visits.
Some owners report a check engine light with a 'Drive-Start Control Malfunction' and a fault code for a stuck turbocharger wastegate actuator. This can cause power loss and may need expensive repairs. It's a concern for long-term reliability.
Complaints include sudden power loss when using the seat cooler and unintended acceleration in a drive-thru. These unpredictable events can be frightening and hard to diagnose, making the car feel unreliable.
“The contact owns a 2025 Lexus RX 350. The contact stated that while driving into a parking space, the vehicle suddenly experienced unintended acceleration and drove forward at a high rate of speed before crashing into the brick wall of an office building. Dur…”
“The car does not alert when a seat belt is not worn in the back seats. This feature is mentioned in the owner's manual, but the car fails to alert when a rear passenger does not buckle their seat belt. I have raised the complaint twice and proved to lexus ser…”

Owners report all warning lights coming on at once, followed by loss of air conditioning and power brakes. Another says the car locked his wife inside and would not start. These failures can leave you stranded or unable to control the vehicle.
A common complaint is a fuel door that won't open due to misalignment, even after dealer repairs. This is a daily annoyance that can prevent refueling and points to fit-and-finish issues.
One owner expressed deep disappointment with brake service on a 2021 NX 300, suggesting brake problems that may not be resolved. Brake issues are safety-critical and should be checked carefully.
Complaints include side mirrors that don't adjust enough for shorter drivers and air conditioning condensers easily damaged by small pebbles. These affect comfort and visibility, and repairs can be costly.
“While driving our Lexus on 8/13/2023 on the interstate under normal driving conditions ALL of our warning lights came on one after another. We also lost air conditioning and power brakes it seemed. We immediately exited and pulled over. Opened the hood and th…”

Buyer analysis
Lexus RX or Lexus NX: which should you buy?
The Lexus NX has fewer issues per year (30.5 vs. 63.5 complaints) and fewer total complaints, but both have zero deaths reported. The RX's higher complaint rate is driven by air bag and electrical problems, while the NX's issues are more often electrical and structural. In practice, the NX may require fewer dealer visits, but both have notable safety-related complaints.
Key differences
- The RX has more than double the annual complaints (63.5 vs. 30.5) and more than double the total complaints (635 vs. 305).
- Air bag complaints are the top issue for the RX (260), often involving unintended acceleration, while the NX's top issue is electrical (97), with warning lights and power loss.
- The RX has 73 crash-related complaints and 67 injuries; the NX has 38 crash-related and 30 injuries.
- Both share recalls for fuel pump and back-over prevention, but the RX also has steering knuckle and instrument cluster recalls, while the NX has steering column and display function recalls.
- Check for unintended acceleration symptoms: test drive at low speeds and in parking situations, and ask if any software updates or recalls address this.
- Inspect the 12-volt battery health and ask about parasitic drain history; a weak battery or repeated jump-starts could signal a recurring issue.
- Test all electrical functions, including warning lights, power brakes, and door locks; look for signs of battery or alternator problems.
- Open and close the fuel door multiple times to ensure it aligns and latches properly, as misalignment is a common complaint.
Before you buy
- Obtain a full vehicle history report and check for open recalls on both models, especially fuel pump and back-over prevention.
- Have a mechanic inspect the 12-volt battery and charging system on both, as electrical drain is reported on both.
- During a test drive, specifically test low-speed acceleration and braking to check for unintended acceleration or brake issues.
- For the RX, ask about turbocharger wastegate actuator repairs if the check engine light is on or has been on.
- For the NX, verify that all warning lights illuminate and then go out, and that the fuel door opens smoothly.
