Model-year records

What the 2016 record can and cannot say

Owners submitted 58 complaints for the 2016 Lexus RX 350 in this database. That count lands about 50 reports above the median complaint count in these records, without adjusting for sales or time on the road.

Unknown Or Other is the most common tag, attached to 19 reports, or 32.8% of this year's submitted complaints. Check that component's coverage terms; the share does not predict its chance of failure.

The largest applicable parts midpoint belongs to Engine replacement or major internal repair at $7,000. Coverage has value only if the administrator accepts both the component and the cause.

Engine & transmission control

Manufacturer documented2016, 2017, 2018, 2019

Bucking on early upshifts or low-speed surge

Lexus's ECM bulletin calls for reprogramming only after a technician reproduces one of two narrow driving patterns.

Lexus documented two related drivability conditions on some 2016 to 2019 RX 350 and RX 350L vehicles: brief back-and-forth bucking just after the first two upshifts, and a rocking surge below 46 mph while the transmission is in a higher gear with the torque converter fully locked. The bulletin specifies ECM reprogramming after a technician reproduces the exact condition and rules out other faults.

Symptoms to compare
  • A brief bucking sensation immediately after a 1 to 2 or 2 to 3 upshift
  • A repeated rocking or surge not directly tied to a shift
  • The surge occurs between 0 and 46 mph with the torque converter in full lock-up
  • The sensation dissipates rather than continuing as a constant vibration

Other ways owners describe it: Lexus jerks when shifting; RX 350 bucks at low speed; car rocks back and forth; rough first to second shift; surging under 50 mph; transmission feels like it is hunting; hesitation then lurch.

Which vehicles the source covers
  • 2016 to 2019 Lexus RX 350
  • Specified 2018 to 2019 RX 350L calibrations are included
  • Drivetrain, WMI and current calibration determine applicability

The bulletin does not set a mileage threshold. It stated Federal Emissions Warranty coverage of 96 months or 80,000 miles for the specified condition, subject to the vehicle's in-service date and eligibility.

Manufacturer position and diagnosis

Lexus directs technicians to reproduce the exact bucking or surge criteria, check for applicable calibration IDs and reprogram the ECM. The bulletin specifically says not to replace the ECM as part of this repair.

Confirm the drive pattern and update the ECM calibrationLexus diagnostic procedure · Road test and reprogramming

A Lexus technician uses vehicle data to reproduce the published condition, checks the current calibration and installs the applicable updated ECM software.

Limit: Do not replace transmission parts solely from the symptom wording. The bulletin applies only when its operating criteria and calibration checks match.

Record when the motion occursBasic observation · One normal trip

From the passenger seat or after the trip, note the road speed and whether the event follows a shift. Add the engine temperature and any warning light.

Limit: Do not attempt repeated acceleration tests in traffic or operate a phone while driving.

Exhaust

Manufacturer documented2016, 2017, 2018, 2019, 2020, 2021, 2022

Exhaust drone on takeoff or light acceleration

A low drone during takeoff is the sound described in Lexus's revised center-pipe bulletin, particularly under gentle acceleration.

Lexus documented a droning noise from the exhaust system on some 2016 to 2022 RX 350 vehicles during takeoff or light acceleration. The published procedure checks whether the vehicle already has the revised center pipe with an added bracket and damper, then replaces the older pipe when the exact condition is confirmed. An exhaust leak or loose heat shield needs separate diagnosis; engine faults can also sound similar.

Symptoms to compare
  • A low-frequency drone or boom is heard during takeoff
  • The sound appears under light rather than heavy acceleration
  • The noise seems to come from the exhaust or beneath the cabin
  • The bulletin condition is reduced by the revised center pipe and damper

Other ways owners describe it: deep humming when accelerating; exhaust resonance in cabin; RX 350 drones from a stop; booming noise under light throttle; low frequency vibration from exhaust; muffler hum at takeoff.

Which vehicles the source covers
  • 2016 to 2022 Lexus RX 350
  • The old versus revised center exhaust pipe is identified during inspection
  • The bulletin does not list the RX 350L or RX 450h for this procedure

The service bulletin uses model year and confirmation of the specific noise, not a mileage threshold. It stated Federal Long-Term Emission Warranty terms of 96 months or 80,000 miles, subject to eligibility.

Manufacturer position and diagnosis

Lexus instructs technicians to confirm the drone and identify whether the revised pipe is already installed. The older center exhaust pipe is then replaced with the countermeasure part.

Inspect for the revised center exhaust pipeProfessional exhaust repair · Workshop inspection and replacement

A Lexus or exhaust technician confirms the exact drone and checks for the bracket and damper that identify the revised pipe. If the old assembly is present and the bulletin applies, it is replaced with the countermeasure part.

Limit: Exhaust components become extremely hot, and the bulletin requires new gaskets plus measurement of the compression springs.

Compare the noise at light throttleBasic observation · One normal trip

During ordinary driving, have a passenger note whether the sound starts only from a stop or also at a steady speed, and whether it changes with engine speed. Record from inside the cabin without placing a device under the vehicle.

Limit: Do not touch or crawl beneath a hot or unsupported vehicle.

Confirm who pays before authorizing work

A recall remedy follows the campaign and VIN eligibility. A service bulletin provides diagnosis or repair instructions; it does not by itself promise payment. Manufacturer warranty extensions and support programs have their own conditions.

Keep a current problem separate from future coverage

These files do not supply a shop quote. Ask for a diagnosis and written estimate, then check recall remedies or existing coverage. A new vehicle service contract generally excludes pre-existing conditions.

Each file retains its original source review date. Historical remedy wording can change; check the current manufacturer notice and NHTSA VIN lookup for your vehicle. The separately dated NHTSA counts elsewhere on this page use a different dataset and scope.
