Lexus RX years to avoid — most common problems

The Lexus RX is associated with exceptional style, excellent practicality, and a generously luxurious interior. It is an attractive vehicle, not just aesthetically but performance-wise too.

Despite the reputation the RX has achieved for itself, not all models deliver as promised. Some of its models replace satisfaction with stress. This article expounds on those Lexus RX years to avoid and why.

Most common Lexus RX problems

Every vehicle has its fair share of problems, and the Lexus RX is no exception. You must know these likely problems before you purchase the car to understand what you are most likely up against. Using this knowledge to construct a maintenance plan perfect for the vehicle will save you money and stress.

Here are the most common problems you should expect from a Lexus RX.

Wandering steering wheel

If your steering wheel wanders, you would have difficulty moving the car in a straight line. You would have to adjust the steering, which can be stressful continually. Worn steering gears, excessive caster, and loose or worn steering linkages are some reasons your steering may wander. Because of this, it’s no wonder that a regular Lexus RX driver may wonder – why does my steering wheel shake at high speed?

Drivers of the 2015 RX 350 complained the most about this issue. Some of the most common causes of the problem on the RX 350 were suspension problems, uneven tire pressure or mismatched tires, steering gear binding, and excessive wheel toe-out.

Oil leakage

Drivers of the 2007 to 2015 RX 350 suffered the most from this issue. They reported that the engine leaked oil while they were driving.

The problem must be identified and resolved as soon as possible. The leakage can cause overheating, which in turn damages other components of the engine. Because replacing a faulty oil line costs less than $100, it is essential that you deal with it right away or as soon as possible.

Defective rain sensors

The Lexus RX 350 features a sensor that recognizes when a downpour begins. It also senses how much rain falls and regulates the wiper’s speed to follow the obtained data.

If you have a 2017 RX 350 redesign, your chances of getting this problem are higher than drivers of other models. The major complaint these 2017 RX 350 drivers have is that the sensors have decreased efficiency at night. There have also been reports of the wiper malfunctioning even when the dial is at maximum sensibility.

Faulty infotainment system

The faults plaguing the infotainment system of the RX 350 are fortunately not severe enough to require extensive repairs. Some drivers, especially those owning 2007, 2010, and 2014 RX 350s, complained of failing Bluetooth features, navigation display, and radio.

Simply checking for and getting the latest software upgrades were enough to rectify this issue.

VVT problems

The variable valve timing (VVT) system reduces the air-fuel mixture entering the engine, reducing emissions. The system inadvertently enhances the vehicle’s power, increasing its maximum speed and improving handling and drivability.

VVT problems have particularly plagued 2007 to 2008 and 2012 models causing them to have their check engine lights, AWD, and traction control warning lights illuminated. Moreover, if the camshaft timing oil control valve is faulty, the affected vehicles would store P0014 and P0012 error codes until they are cleared manually and the oil control valve replaced.

Transmission failure

Some drivers of the RX 350 have reported transmission issues that cause their RX 350 to hesitate before moving and eventually lose power some days after. The 2013 model was most notorious for having this problem.

Bad bearings, faulty control modules, and contaminated or low transmission fluids are the primary reasons the RX350 develops transmission failure.

AC failure

Some AC units of the RX 350 have been reported to blow hot air instead of cold air. The cause of the issue is attributed to a defective AC amplifier. Drivers of the 2007 to 2013 RX 350s were most affected by this issue. If the A/C blows hot air, it’s a big deal for driving convenience, especially during summer time.

Engine failure

Some RX 350s have been known to break down without warning despite their drivers’ care. The 2009 model was most notorious for keeping drivers stranded because of this issue. Improper lubrication, oil leaks, overheating, and detonation are the common reasons why this occurs on the RX 350.

Rattling front doors

It may seem minor, but this problem is a considerable safety hazard. Drivers complained of the front door of the RX 350 rattling while they were speeding on the freeway. In severe cases, the doors came loose, making it a danger to the driver, passenger, and other motorists who may be unfortunate enough to be within reach.

The cause of the issue has been tied chiefly to worn-out window regulators, misaligned doors, loose windows, and loose nuts and bolts. It is best if you get a professional to correctly identify where the issue is coming from and rectify it before you keep using the vehicle.

Illuminated SRS

The function of the supplementary restraint system (SRS) on a vehicle is to deploy and protect its occupants when a crash happens. The deployed object could be an airbag or something that works like it.

Many 2007 to 2010 and 2013 to 2014 RX 350 models continually had the warning light on for days. When diagnostic tests were run on the vehicle, most returned error codes B0111 and B01166 which suggest a wet airbag module, faulty sensors, damaged airbag clock springs, or a depleted airbag backup battery.

Letting your mechanic handle these repairs is best, as working on the SRS system can get pretty dangerous with one wrong move.

Which Lexus RX years to avoid?

All the RX350 models are prone to having problems, but some have too much of it that you are better off avoiding them. Below are the Lexus RX years you should avoid if you want your money’s worth.

Second-generation RX (2007-2008 model years)

The 2007 model had the most problems. Drivers complained tirelessly about the issues that continually sprung up from the model to the point where others looking for an RX 350 learned to avoid the vehicle altogether.

Aside from the common problems with other RX 350s, like oil leaks, the 2007 model also had water pump leaks and rack and pinion leaks. These two leaks cost up to $4,000 to repair. For the safety and security of your pocket, you should avoid this model too.

The 2008 RX 350 is reliable but features the most common problems you can expect from a Lexus RX. You can expect cracked dashboards, power steering system leaks, and ignition coil failures with the 2008 model, making it inconvenient as these issues often materialize at odd times.

Third-generation RX (2010 model year)

Though the number of complaints for the 2010 model year is not like that of 2007, owning this car is still an inconvenience. It had massive oil leak problems and loss of oil pressure. The AC amplifier was also prone to failing quite early, leaving you with a faulty air conditioner.

Furthermore, you would have to upgrade the heater, radio, and GPS software frequently. Practically all the common problems the RX350 could suffer were present in the 2010 model.

Fourth-generation RX (2016-2017 model years)

The main problem that makes the 2016 RX 350 model undesirable is its acceleration issue. Drivers have complained about its speed and acceleration even when the brake pedal is depressed.

The model was also notorious for its stalling engine. The structural integrity was also another cause for concern, as many drivers reported the sunroof exploding unexpectedly. The model is a dangerous problem and a potential cause of crashes and accidents.

The 2017 model inherited the engine stalling and sunroof explosion problems from the 2016 model but had some additions that made the 2016 model look better.

There are some electrical problems and a fault in the AC drain plug design that promoted damage to the carpeting and padding. It also had brake and transmission issues.
