2025 Toyota Grand Highlander

On 11/02/2025 with the cruise at 55mph all glass closed. Heater on with no vehicles around, the sunroof exploded. It pushed up from the inside. With less than 9k miles on the vehicle. It took my dealer 8 days to look at it then Toyota denied the warranty. Then Quoted me over $2,100 to replace. This vehicle isn't safe to drive as told to me from the dealer.

There is a coolant leak in the hybrid radiator caused by a puncture. When taken to the dealer, they said a rock must have punctured it. The dealer currently has the part. Me, my husband, and 2 children were driving on I-5 when the car stopped accelerating and a "hybrid malfucntion" code and "engine malfunction" code started flashing. Prior to this, there were no warnings. I was thankfully able to full over safely, but we were stuck on the side of I-5 for at least an hour waiting for a tow. I am reading online that this is an issue with the car and seems to be a design flaw. The gaps in the grill are too large, and there is no mesh or anything else behind the grill to protect the front end of the car.

Sun roof shattered unprovoked in 2 month old vehicle while driving slowly in parking lot. We didn't know what happened at first but then opened interior lining and the shattered glass fell into the cabin; nobody was hurt. when we took this to dealership, we were told this wasn't under warrantee and we had to get it fixed independently. I filed a complaint with Toyota Care but they denied covering cost to fix the shattered sun roof. We did not have the shattered sun roof inspected by anybody else but it has been fixed by glass shop.

I am told my 2025 Grand Highlander has a hole in the AC Condenser from "road debris" according to a Toyota dealership leading to no air conditioning. I've never taken the car off-roading. A simple google search shows that others are having this issue and are buying extra netting to protect it from happening again. I'm told I need to pay $1,800 to have this fixed when I haven't even had the car for a year. This seems like a design flaw that needs to be addressed.

I have experienced intermittent transmission issues. Specifically, the car often fails to shift gracefully from first gear, resulting in rough or hard shifts that are jarring and unsafe, particularly during acceleration or in stop-and-go traffic. On multiple occasions, the vehicle has refused to shift correctly, requiring me to pull over, turn the car completely off, and restart it to restore proper shifting functionality. This issue is not only inconvenient but also poses a significant safety risk, especially when merging into traffic or navigating busy roads. For a vehicle marketed as a reliable and family-friendly SUV, these transmission problems are unacceptable. The transmission issues have significantly undermined my confidence in the vehicle’s safety and reliability, particularly as I rely on it for family transportation. The need to pull over and restart the car to address shifting problems is not only inconvenient but also dangerous in certain driving conditions. Furthermore, the reports of similar issues among other owners indicate that these problems may persist without proper intervention from Toyota.

Apparently, a rock flew into the front grill striking the radiator (which is located directly behind the grill) and put a hole in it. This caused fluid to leak and fortunately during a routine maintenance check (my first service) on 8/15/25, it was discovered. The car was deemed not safe to drive until repairs were made. I submitted it to my insurance company and they inspected it and verified the issue. The radiator was replaced by Toyota at the dealership where I purchased the vehicle. They said they heard of a few cases, but I went online and discovered several vehicles that had this happen. Apparently the grill on the new highlanders is the issue - it has wide openings and the radiator is directly behind it. I am purchasing a bra and some mesh to place behind the grill in order to prevent another incident. No warning lights or indicators came on and the dealership said it would've eventually when it got hot enough. Fortunately, most of my driving was local after the incident occurred so the vehicle didn't have time to overheat. I am thankful it was discovered before I was stranded.

I have taken the vehicle to Hillside Toyota on 05/05/25 and 07/21/25 where they inspected the vehicle but could not identify the source of the leak” or “attempted a repair, but the issue persists.
