This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
Cabin boom noise reported from the first day of ownership whenever driving the vehicle under 50mph. Noise is a low bass frequency below 30hz that reverberates throughout entire vehicle, causing severe ear pain, headaches, nausea, and disorientation. The only way to tolerate driving this vehicle is to wear airplane pressure earplugs, which poses a safety concern for not being able to hear surroundings while driving. The cabin boom seems to be coming from the suspension. Dealership foreman and corporate field tech looked at vehicle and denied any problem, stating this was -??normal for this new vehicle-?? and refused to investigate or try any diagnostics. The cabin boom sound is recorded on video, and is such a low frequency you must use noise canceling headphones to hear it on video (confirmed by professional audio engineer). This sound/pressure can be heard and felt by other people in the car, unless they already have low frequency hearing loss. This problem creates physical illness and is a huge safety concern for this brand new model Grand Highlander. Dozens of people are reporting the same problem on Toyota forums as well for their new Grand Highlanders.
Reverberation noise, also commonly referred to by other owners as -??boom or acoustic boom.-?? The entire cabin vibrates as if a shock wave is being sent through it. Mostly occurred when hitting small to large bumps under 45 mph and also happens often while breaking (even on flat and smooth pavement). On highway over 50mph there is a constant pressure within the cabin that significantly effects the ears and makes me nauseous and gives me a dazed-like feeling. Every person that has been in my vehicle has asked me what was wrong with it. A Toyota service tech told me they didn-??t find anything wrong with it, but I still can-??t drive it for more than 20 minutes without feeling sick. Please help.
I have a brand new Grand Highlander Limited with a Panoramic roof, and since the day I took it home, I have noticed a deep bass sound and ear pressure/cabin pressure when driving below 40mph on residential roads. It is very low-frequency and causes headaches, ear pain, and ringing after driving the car. I have taken it to 2 separate dealerships for diagnostic, and they agree they hear the sound and feel the cabin pressure but state it is the vehicle's design. However, most owners aren't experiencing the same issue, so it's not a feature but more of a flaw in some of them.
When turn left or right i hear a rotating poping noise only goes away when you go straight. I have hread others complaining about the issue. To my understanding and knowledge the axles are bad. This can cause premature failure in other suspension parts and tire wear.
Very loud Popping/clicking noises when turning/accelerating from a stop. Only had 2,162 miles on the vehicle when this happened. While driving, it also felt like my front driver side wheel was wobbling-very unsafe. Called Toyota roadside assistance and had car towed to dealership. Lead service technician was able to reproduce the popping and clicking noise. Dealership opened a case with Toyota, and had engineers come look. 10 days later, they called to tell me that they have to replace CV axle. Car was in the shop 18 days total. This problem shouldn-??t be happening to a brand new car with 2,000 miles on it. There are MULTIPLE reports of this same thing happening to MULTIPLE Grand Highlander owners-on a -??Grand Highlander Owners-?? Facebook page. Some have had to have both cv axles replaced.
