2017 Lexus Rx

DAMPER SERVO SUB-ASSEMBLY, AIR CONDITIONER RADIATOR, NO. 2 Part Number: 8710608120 Which also called the bend door actuator failed on my 2017 RX450h at 80,000 mile.The part or door opens to mix hot air form the heating core and cold air to supply heat to the interior of the vehicle. When the bend door actuator part failed you have no heat and to replace it you have to he the dash removed (poor engineer design) and face bills for service over 6,000 dollars. This part failed appears to be prevalent with this manufacturer. Other manufacturers such as Mercedes benz, Porsche, and Honda etc. do not appear to suffer from this part failure problem at the same mileage. This appears to be a lemon part form this Manufacturer.

I just picked My Car up from Bakersfield Motor Ciry Lexus . My engine was replaced with a engine at this location with 65k . I have now notice my car jerk during acceleration from a stop position or uphill possibly from the transmission . I respectfully requesting a claim be opened on this issue as I didn't have the issue until engine replacement. I am also requesting a courtesy evaluation and stress test on the transmission at my home dealership Newport Beach Lexus. Ever since engine replacement the car has been bucking during acceleration 0 to 45.

It was found during inspection of front break calipers that rubber dust boots on 3 out of 4 pistons (2 pistons per caliper) were torn apart. Chunks of cut out rubber boots were found inside the pistons. The car never had break work done since the time it was manufactured. The brake pads on both front wheels are still factory original. The only way for dust boots to get damaged is to have improper installation during car assembly process where rubber boot is not tacked fully inside caliper. The issue would result in premature wear of piston seals dust boot supposed to protect. Wearing off seals would result in leak of break fluid and potential sudden loss of break functionality. The workmanship issue is likely to be impacting other vehicles assembled on the same factory floor by the same employee.

When checking the emergency SOS function in my car I found that it did not work. I called Lexus support and was told that the following safety systems would no longer be operative: Lexus Enform Safety Connect including Automatic Collision Notification; Enhanced Roadside Assistance; Emergency Assistance Button and Stolen Vehicle Locator; Lexus Enform Remote including Remote Engine Start/Stop, Door Lock/Unlock, Vehicle Finder, Guest Driver Monitor, Vehicle Status and Alerts, Key Fob Remote Start, and Integration with Alexa® and The Google Assistant; Lexus Enform Destination Assist including 24-hour live response center agent; Lexus Enform Service Connect including Vehicle Health Report, Vehicle Alerts, and Maintenance Alerts; These include safety systems that I rely on, especially when driving on interstate highways, and were included when I purchased my car. I had no warning that the services would cease to function in October of this year. Lexus states that these systems will no longer function because telecommunications providers will no longer support 3G service. This is certainly a safety issue for me and for other drivers and I believe that Lexus should be required to modify the hardware/software in these vehicles to function in a 4G/5G environment. Lexus representatives state that Lexus has no plans to correct these safety issues. I am requesting that NHTSA review this matter as a highway safety issue.

On 5/8/2020, Northtown Lexus replaced or repaired the vacuum pump. Northtown Lexus required the vehicle to be returned for repair twice, following the initial repair on 5/8/2020. After three attempts, the vehicle's vacuum pump (per a factory recall) is not functioning properly. Northtown Lexus refuses to further diagnosis this defective vacuum pump and continued to decline any and all requests for repair. The vehicle operates abnormally ever since this factory recall was originally addressed by Northtown Lexus on 5/8/2020.

Sunroof Glass Failure Report: I was traveling on the interstate at the speed limit and there was a loud bang, which after I pulled over, discovered that the sunroof had "exploded". There was no sign of anything hitting it and the weather was typical for the Texas Gulf Coast in a July morning. Luckily, the underneath cover for the sunroof was closed, because several pounds of glass fragments were released in the sunroof failure and would have been all over the passenger compartment of the Lexus. This is a major safety issue, especially if a child is fastened in a car seat with this problem directly overhead. This issue has been reported by numerous other Lexus owners and seems to occur often enough that it should be a concern for the manufacturer, but I am not aware that they have taken any action on this. A photo of the failed sunroof is included.
