Let me share my experience with a brand new Toyota Corolla Altis (G) Automatic. On taking the car out to drive in the streets of Bangalore the joy of driving a brand new car was cut short by the sound and feel of the car's chassis scraping on a speed bump. At that time there were just 4 passengers and the trunk had two normal suitcases (standard luggage). I thought that maybe I need to drive slower and tried the next few bumps. Despite that, the car kept hitting the bumps from time to time. After returning from my journey, I went to the dealer's workshop (Ravindu Toyota, Bangalore). The personnel were extremely courteous and offered to test drive on the nearby roads to verify if the suspension was indeed faulty. Unfortunately, under able driving of the Toyota folks, the car cleared all the bumps. We tried with 4 passengers and once again it cleared the bumps. I was told that I need to avoid pressing the brake after the front wheels glide over the bump. Otherwise, the car sits down a little and touches the bump. I agreed and decided to do that going forward.
Today, once again on the streets of Bangalore (different roads), with five people in the car (and no luggage), and driving as directed, the car once again scraped the muffler after crossing the bump.
My concerns are below:
Roads in India invariably have unscientific speed breakers (bumps). We definitely need vehicles to clear them.
Using an automatic, it is almost impossible to drive without pressing the brake before or after a bump. Because the car immediately starts to accelerate. And most of the time there is some obstruction or the other in front (vehicle etc) that requires us to brake.
I had never heard of Toyota Corolla having a 'ground scraping' issue - though it was more common heard for Honda Civic. Can Toyota consider adding some spacers to the suspension to let the car ride a little stiffer and prevent hitting the road?
