When owners complained
A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

TIRES
November 2023 we purchased 4 new Continental PURECONTACT LS 245/45/R19 from Discount Tire in Evansville Indiana. We’ve driven almost 17,000 miles on the tires. Noticed 2 tires are splitting on the sidewall near the tread. The one I’m reporting is dangerously split (resembles a re-tread tire).

Stopping without notice can cause an accident and any of the issues can cause safety issues. What I sent them. I am writing to express my concerns regarding a series of issues with my 2017 BMW 740i and to request your assistance in resolving these matters. I have been working with my local BMW dealership to address several problems, but I believe there may be underlying issues that require further attention. I would appreciate it if you could review my case and consider the points outlined below. Background: Recently, my vehicle was brought in for service to replace the spark plugs and address a few concerns, including the replacement of the fuel tank cover. During this visit, it was discovered that the pressure control valve was faulty and needed replacement. I was not previously informed of any issues with the pressure valve, and I have learned that BMW has issued an extended warranty on this part due to known faults. My understanding is that a faulty pressure valve can cause erratic fuel pressure, leading to premature spark plug failure. Given that my car has only been driven about 8,000 miles annually and is used weekly, not sitting idle for long periods, the spark plugs should still have life left. However, they may have worn prematurely due to the pressure valve issue. Concerns: Pressure Control Valve and Spark Plug Failure: It is highly unusual for three spark plugs to fail simultaneously, as spark plugs generally wear out gradually over time. In most cases, one spark plug would fail before the others if there were a gradual wear issue. The simultaneous failure of three spark plugs suggests a potential underlying issue, such as a problem with the ignition system, electrical issues, or a direct result of a faulty pressure control valve. I request that BMW cover the replacement cost of the spark plugs under the extended warranty for the pressure valve, considering the potential causation between these issues. Hard Jerk When
