Lexus IS250 Maintenance Update
It finally happened—around 85,000 miles, my 2007 Lexus IS250 displayed the dreaded Check Engine Light and VSC indicators. I had just changed the oil at the dealer a few weeks prior and replaced the rear axle and front bushings, so it was frustrating to see my dashboard light up like a Christmas tree right after.
Diagnosis
I returned to the dealer, where they determined the issues were a dead O2 sensor and a leaking valve cover gasket. They believe that oil dripping from the gasket fell onto the O2 sensor, leading to its failure.
Repair Costs
The total bill for the repairs came to about $1,300:
- O2 Sensor Replacement: $600
- Valve Cover Gasket Replacement: $700
Additional Maintenance
In addition to resolving the Check Engine light, I also had some other maintenance and repairs done. The total cost for the month reached $4,050, which breaks down as follows:
- Oil Change: $250
- Rear Axle Replacement: $1,700
- Front Bushings Replacement: $800
