2017 Toyota RAV4 problems

UNKNOWN OR OTHER

The sunroof/moonroof glass on my 2017 Toyota RAV4 XLE suddenly shattered while I was driving on the highway. I heard a very loud explosion-like sound, and the sunroof glass broke unexpectedly. I did not observe any object, rock, or road debris striking the sunroof before it shattered. The remaining damaged sunroof and vehicle are currently available for inspection upon request. This incident put my safety and the safety of others at risk because the sunroof shattered unexpectedly while I was traveling on the highway. The sudden loud sound startled me while I was driving, and broken glass was left across the sunroof area and continued to break and fall from the damaged glass. I was concerned that additional pieces could come loose while the vehicle was being driven. The problem has not yet been reproduced or confirmed by a Toyota dealership or independent repair facility. The sunroof has not yet been professionally repaired. At this time, the vehicle and sunroof have not been inspected by Toyota or a Toyota dealership regarding the cause of the failure. I have photographs and/or video documenting the condition of the sunroof after the incident. There were no warning lights, dashboard messages, or other warning symptoms before the sunroof shattered. The failure happened suddenly and without warning while I was driving on the highway.

AIR BAGS

This vehicle has twice had the same issue where the sunroof drain lines become clogged or dislocated and the water fills the liner in the front driver and passenger seats resulting in flooding in the compartment and mold damage throughout the interior. the mole spore are transmitted throughout the interior. The water damaged the airbags and the electrical harness in the dash of the car resulting in the dashboard electrical system shutting off and restarting spontaneously while driving. The leaks were repairs and the interior replaces in october 2023 and the same incident has recurred in august 2026. The claims adjuster recommends that the entire wiring harness, airbags, and carpets, seats and liners be replaced for health and safety of passengers.

STRUCTURE:BODY:HATCHBACK/LIFTGATE

The liftgate on my 2017 Toyota RAV4 has been having issues for a couple of months. Makes a horrific noise when opening and closing. On several occasions it won't even open but about 5 inches then stops. The driver's side door won't lock/unlock with the smart key fob. I have to manually lock it and then use the "key" in the fob to unlock it. It is very hard to turn the key and I am always afraid it is going to break off in the lock. I feel this is dangerous for me that the time it takes to do this, something could happen to me. I have checked a couple of places for repair of the lock and it can run between $600 and $800 per lock.

My 2017 Toyota RAV4 suddenly caught fire while it was parked in front of my home. The vehicle was turned off and had been parked for several minutes. Without any warning, flames started in the battery area and rapidly spread, resulting in a total loss of the vehicle. The Wylie, Texas Fire Department responded and extinguished the fire. Component or System Involved: Exact cause UNKNOWN. Fire appears to have originated from the engine compartment. The remains of the vehicle are available for inspection upon request by NHTSA, Toyota, or investigators. Safety Risk: This was a severe and unexpected fire with no warning and posed a serious risk to my family, neighbors, and surrounding property. The fire could have spread to my home and other vehicles nearby. It created a dangerous situation for anyone in the area. Reproduction / Confirmation: The problem cannot be reproduced because the vehicle is a total loss. No prior mechanical issues or symptoms suggested this could happen. Inspection Status: The vehicle has been inspected by the Wylie Fire Department, and my insurance company has opened a case and is investigating. Toyota USA has also opened a case (# [INSERT CASE NUMBER]) and is expected to review the incident. No final cause has been determined yet.

VEHICLE SPEED CONTROL

While driving the vehicle on an uphill stretch of highway with cruise control set at approximately 65 mph, the vehicle suddenly slowed down without warning. A distinct clunk was heard at the same moment. The cruise control system attempted to restore speed, and the engine became noticeably louder, but the vehicle struggled to return to the set speed. The driver tapped the brake to disengage cruise control and manually pressed the accelerator to resume normal speed. The trip was completed without additional events. After parking, the check engine light illuminated and the cruise control system became disabled on all subsequent drives. No warning indicators were present at the time of the initial failure, and there were no vehicles ahead that would have triggered the collision-avoidance system. Two days later, the vehicle became an intermittent no-start and eventually failed to start entirely. The vehicle was towed to a dealership for inspection. Technicians confirmed an electrical malfunction and reported that the multiplex ECU was likely experiencing an internal short. A parasitic draw test showed an abnormally high current draw of approximately 113 mA, which disappeared when the dome-light fuse and later the multiplex ECU were disconnected. The failure is intermittent and appears to involve an internal electrical short within the multiplex ECU. The sudden loss of cruise control function, abrupt deceleration, and subsequent intermittent electrical behavior created a safety risk, as the electrical malfunction occurred without warning while the vehicle was in motion. The issue was confirmed by a dealership service department.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

My 2017 Toyota RAV4 XLE is experiencing unsafe behavior with the Adaptive Cruise Control (ACC). When driving around modest or slight turns, the ACC frequently loses tracking of the vehicle ahead and suddenly accelerates, then harshly brakes once it reacquires the vehicle. This creates a jerking motion and significantly reduces my confidence in the system. On one occasion while traveling approximately 45 miles per hour on a slight curve, the ACC began rapidly accelerating toward the vehicle in front of me as if no vehicle was there, forcing me to perform an emergency manual takeover and disengage the ACC to avoid a potential rear end collision. This issue is repeatable and appears to be related to how the ACC detects vehicles ahead while cornering. I am requesting that this behavior be investigated as a potential safety defect.

The rear lift hatch on my 2017 Toyota RAV4 is not working properly. It can be raised without a problem most of the time but not lowered without a lot of effort and time. It might go down several inches and stop before going back up again causing me to have to start the process all over again. It definitely could present a danger if someone tried to force it up or down or if they got a body part under it while it was doing its weird motions. Plus it would not be safe to drive it unless it lowered all the way and latched. I did take it in to my Toyota mechanic who acknowledged the problem and said the only remedy was to replace parts at a cost of somewhere between $1200 and $1300. Since the issue with my rear lift hatch started a year ago, I have read numerous complaints from other persons who are having the same issue. My mechanic confirms that he has had a number of vehicles brought to him with the same or similar issue. I strongly feel that there should be a recall. I have been a loyal Toyota owner for many years and over the years have steered numerous persons toward purchasing a Toyota. My Rav4 is available for inspection if that is necessary.

SERVICE BRAKES

The brake system on my 2017 Toyota RAV4 LE has repeatedly failed to provide normal stopping power, even after the replacement of pads and rotors in July 2025. This poses a serious safety hazard and may indicate a defect in the braking system.

POWER TRAIN

While driving on or around 6/5/25, an active recall on my vehicle caused damage to my battery connections causing my vehicle to completely shut off while driving on an highway exit ramp. I almost lost complete control of the vehicle. Thankfully, the vehicle turned back on and I was able to get the vehicle to safety. I had to get the car towed and repaired. The repair was directly related to the damage from an active recall issue being open without remedy for over 3 years on my vehicle. When I asked Toyota for reimbursement of under $200 they refused. This is a safety issue beyond the recall and I am concerned this is going to happen to someone else and there are going to be deaths. Toyota needs to stand by their recall too and may the financial aspect correct with me. Other members of the public need to be aware of the issues beyond their recall that can affect their cars and that Toyota is requiring them to be responsible for the damage that was caused while waiting on a remedy to the recall.
