2019 Toyota RAV4 electrical system problems

“As soon as my vehicle hit 100K mileages and there's "AWD System malfunction" sign showed up on dash. Got it done replaced it cost roughly more than $500. After 2 days later another problem shows up on dash this time it was "engine maintenance required" show on dash again. Heard people had the same issue to whoever own 2019 RAV4 and they all had the same for those 2 issues. Toyota company should pay attention for these kind of problems or like some of of recall.”

“Display of RAV4 Hybrid is malfunctioning as it randomly turns on and off at frequent intervals, the screen turns on an off in a similar manner, the display controls are not operative even if displayed. This occurred right after the Dealer (355 Toyota of Rockville, [XXX] ) conducted a recall procedure on a wire harness. Immediately after these repairs, it was noticed that the display started to malfunction. It has never malfunctioned before. I went back to the Dealership and the manager said that the display problem was unrelated to the recall maintenance. So I am reporting it here.”

“A coolant leak from the flow shut‑off valve caused the engine maintenance warning light to remain on for an extended period. This issue is covered under Toyota Customer Support Program 24TE04. The warning light is a safety concern because it indicates an active engine‑related malfunction and can mask other warnings. The defect was first diagnosed by a Toyota dealership at approximately 97,000 miles, well within the CSP coverage window. The dealership stated the vehicle “did not meet criteria” and refused to perform the repair, even though the symptoms matched those described in the CSP. The issue continued until a second Toyota dealership later confirmed the same defect and replaced the coolant bypass valve. Because the vehicle had since exceeded 100,000 miles, Toyota refused to cover the repair under the CSP, despite the defect being documented earlier within the coverage period. Multiple attempts to resolve the issue with Toyota corporate have resulted in no returned calls or meaningful response. The defect caused prolonged operation with an illuminated engine warning light, which presents a safety risk and indicates a failure to properly address a known…”

“Braking while pulling into a parking space. Instead of slowing down the car accelerated and went over the curb. Maintained pressure on the break but it did not slow the car. Instead the car kept accelerating down an embankment, across an empty street and towards a telephone pole. Turning the steering wheel to the left to avoid the telephone pole the car further descended into a ditch. The car had to be towed and is now deemed to be totaled. The brake- pads had been inspected during a routine maintenance check the day before this accident occurred and they were good. No other vehicle was involved. My personal injury was an abrasion and bruise where my seat belt did it's job. My muscles are sore. The side airbags did deploy after the car stopped. The floor mats were locked in place.”

“Safety Defect: Data Communication Module (DCM) Failure Affecting Hands-Free Microphone and Safety Connect / SOS Emergency System Vehicle: 2019 Toyota RAV4 Hybrid LE The DCM (which controls both the CarPlay/Bluetooth hands-free microphone and the Safety Connect SOS emergency button) suddenly failed without any warning or accident. Symptoms: - No one can hear me during CarPlay or Bluetooth calls (microphone inoperative). - Safety Connect / SOS light became intermittent or inoperative (directly impacts emergency calling, crash notification, and roadside assistance). This is a known recurring issue documented in Toyota TSBs T-SB-0112-20 and T-SB-0089-21. Toyota of Hackensack diagnosed it and quoted $1,300 for DCM replacement/update while charging me $200 for diagnosis. They did not disclose during the multipoint inspection that this is a documented safety-related DCM fault. I performed the manufacturer-recommended 12V battery disconnect reset (standard TSB procedure), which fully restored the microphone and returned the SOS light to solid green. However, this is only a temporary fix for a known defect. This failure compromises hands-free calling while driving and…”

“The contact owns a 2019 Toyota Rav4. The contact stated that while seated in the vehicle, while the vehicle was parked, there was an abnormally strong plastic burning odor inside the vehicle.

The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not notified of the failure. The failure mileage was approximately 129,000.”
